Jingdian Group Said It Would Strengthen Cooperation with Weitian Technology in Mini Led

In recent years, led factory crystal power has continued to add code and layout new undertakings such as mini led and VCSEL.

Yesterday, Jingdian announced that its subsidiary's bright spot investment participated in the subscription of 10000 private ordinary shares of Weitian technology. In the future, the shareholding proportion of Jingdian group in Weitian technology will increase to 52.5%, and the two sides will also strengthen cooperation in mini led.

In May last year, Jingdian announced that the group's operation strategy had changed and was divided into three companies according to business conditions, namely Jingdian, Jingdian semiconductor and Jingdian technology. This is the first time that Jingdian has proposed a spin off plan since its establishment 21 years ago.

Among them, crystal operates quaternion led, blue LED, VCSEL, long wavelength LED and laser (far infrared above 1000nm) and other product lines. Long wavelength products will focus on biomedical applications, such as measuring blood glucose or blood oxygen.

Crystal semiconductor is mainly engaged in OEM business, covering the whole process from epitaxial to grain, providing 4-inch or 6-inch OEM services. 850nm and 940nm are the main products, and the OEM products include VCSEL, electronic components (GaN / Si), etc.

Crystal technology focuses on the operation of module and component manufacturing processes, including CSP led, mini led and micro led, sensors, solar cells, etc. for some LEDs that cannot adopt traditional packaging technology, new manufacturing processes are adopted. For example, customized products such as mini led and micro led.

It is reported that the participation of Jingdian in the private capital increase of Weitian technology is mainly based on the production expansion demand of Weitian technology. It is expected that this will help Jingdian strengthen the supply of mini led in the future. The participation in the subscription has raised the shareholding proportion of Jingdian group in Weitian technology to about 52.5%, and the shareholding proportion has been more than half.

At the beginning of entering the field of mini led, Jingdian directly provided customers with mini LED chips, but some system factory customers need Mini LED module solutions to deal with design problems such as packaging and PCB. Aware of the customer's demand for mini LED modules, Jingdian decided to cut out the module business and set up Yuanfeng new technology, a 100% owned subsidiary, at the beginning of this year.

Yuanfeng new technology is responsible for supply chain integration, R & D and design, and small-scale proofing and trial production. The mass production is entrusted to the partner Weitian technology. Weitian used to purchase LED chips from Jingdian and produce them for a long time, mainly for high-power packaging and module products. Later, when it launched private placement for production expansion, Jingdian also used Jingdian Bright spot investment and Yuanfeng new technology increased their holdings and jumped to the largest shareholder.

What Solute Will Be Replaced by Liquid Electrolyte in Commercial Lithium Ion Battery?
What Solute Will Be Replaced by Liquid Electrolyte in Commercial Lithium Ion Battery?
Replacing the liquid electrolyte in commercial lithium-ion battery with solid electrolyte and combining with lithium metal negative electrode to form an all solid-state lithium-ion battery system is expected to fundamentally solve the safety problem of lithium-ion battery system and greatly improve the energy density. Lithium ion solid electrolyte materials should have room temperature conductivity comparable to liquid electrolyte, good chemical and electrochemical stability and mechanical properties, and have excellent contact and compatibility with electrode materials. Traditionally, it is believed that the smaller anionic charge in the crystal is often considered to be conducive to the rapid transmission of lithium ions, that is, negative monovalent anions are more conducive to cation diffusion than negative divalent anions.Zhu Hong's research team from Shanghai Jiaotong University studied the effects of anion charge and lattice volume on lithium ion occupation stability and lithium ion migration by constructing anion sublattice model and combining density functional theory calculation. It was found that only by comprehensively regulating the coordination number of anion charge and lithium ion can the activation energy barrier of lithium ion migration be effectively reduced. More anionic charge and larger lattice volume will improve the relative stability of lithium anion tetrahedron, making lithium ions more inclined to occupy tetrahedral sites. For the migration of lithium ions from a tetrahedral center through an octahedral transition state to an adjacent tetrahedral center, that is, the Tet OCT tet path, the less the negative charge of anions, the lower the migration activation barrier of lithium ions. For the migration of lithium ions from an octahedral center through a tetrahedral transition state to an adjacent octahedral center, that is, the OCT tet OCT path, the more negative anionic charges, the lower the migration activation barrier of lithium ions. Based on this discovery, the research team proposed a new design guideline for developing and optimizing superionic conductors using anion sublattice model, that is, by adjusting non lithium elements in the same crystal structure to obtain appropriate electronegativity differences between anionic elements and non lithium cationic elements, so as to realize low lithium ion migration activation barrier. It provides some theoretical guidance for efficient high-throughput calculation, screening of new lithium-ion superconductors and optimization of existing lithium-ion superconductors.This paper was recently published in npj computational materials 6:47 (2020).Anion charge and lattice volume dependent lithium ion migration in compounds with fcc anion sublatticesZhenming Xu, Xin Chen, Ronghan Chen, Xin Li & Hong ZhuProper design principles are essential for the efficient development of superionic conductors. However, the existing design principles are mainly proposed from the perspective of crystal structures. In this work, the face-centered cubic (fcc) anion sublattices were creatively constructed to study the effects of anion charge and lattice volume on the stability of lithium ion occupation and lithium ion migration by the density functional theory calculations. Both the large negative anion charges and large lattice volumes would increase the relative stabilities of lithium-anion tetrahedr on, making lithium ions prefer to occupy the tetrahedral sites. For a tetrahedral lithium ion migration to its adjacent tetrahedral site through an octahedral transition state, the smaller the negative anion charge is, the lower the lithium ion migration barrier will be. While for an octahedral lithium ion migration to its adjacent octahedral site through a tetrahedral transition state, the more negative anion charge is, the lower the lithium ion migration barrier will be. New design principles for developing and optimizing superionic conductors with the fcc anion sublattice were proposed. Low lithium ion migration barriers would be achieved by adjusting the non-lithium elements within the same crystal structure to obtain the desired electronegativity difference between the anion element and the non-lithium cation element.

From the Perspective of Bridge Lighting System, the Use of LED Technology Has Become a Trend
From the Perspective of Bridge Lighting System, the Use of LED Technology Has Become a Trend
In recent years, with the rapid development of LED industry, the role of LED in urban lighting engineering is becoming more and more obvious. With excellent lighting and energy-saving effects, LED is widely used in public places such as roads and landscape lighting. Nowadays, more and more bridges use LED lighting systems. Some "most" large projects even use LED application products and intelligent control systems in an all-round way, which shows that the use of LED technology has become a trend.   The following small series will introduce the specific situation of LED lighting in the four bridges.Bazhong's longest river crossing bridge Dongmen Bridge opened to traffic LED lights to create beautiful sceneryBazhong Dongmen bridge was launched on January 30, 2015. It is understood that this bridge, known as the most fashionable bridge in Bazhong, connects Zhongba huangjiagou and Zhongyang trunk road in the East, yongjingwan and Nanba Street Garden in the old urban area in the west, and connects the Second Ring Road, with a total length of 762 meters. This figure also broke the previous records of 352m of Huifeng bridge and 431.683m of maliuwan bridge, becoming the longest bridge in Bazhong at present.According to the designer, the main tower of the bridge adopts LED high-power projection lamp structure, and the stay cable adopts LED point light source. Whenever night falls, these LED lighting sources begin to show a variety of effects such as night sky and star flash, and can change colors with spring, summer, autumn and winter. The pier and arch bridge are lit by LED wall washing lamp and LED projection lamp in layers to show the penetration, three-dimensional and hierarchical feeling of the bridge body through the light, and the light shows the reflection effect in the water. Therefore, whether day or night, the bridge is a beautiful scenery on the Ba River.The most intelligent bridge in the United States is equipped with Philips intelligent lighting systemThe most intelligent bridge in the United States - the new tappanzee bridge in New York, also known as the "New York bridge", will be opened at the end of 2016, equipped with flexible and low-power fashionable LED lighting system, 3.1 miles long, across the Hudson River.The intelligent lighting system of New York bridge is composed of two Philips intelligent LED series, including 2700 color kinetics led escrow and more than 500 white road view LED lighting tubes. The software behind the intelligent LED system of the New York bridge is completely based on cloud services. Through Philips's active site and city touch control pages, you can set and control the operation mode and pattern of the bridge led lighting system.Top LED technology of the world's longest sea crossing bridge "Hong Kong Zhuhai Macao Bridge"The world's longest sea crossing bridge "Hong Kong Zhuhai Macao Bridge" is expected to be completed in August this year. The main works of artificial island and subsea tunnel are expected to be completed in the first half of 2017, and can be commissioned and opened to traffic by the end of 2017.It is understood that all LED street lights, LED tunnel lights, led variable information boards, LED landscape lights and corresponding intelligent control systems of the bridge have confirmed and adopted Shanghai Sansi products after repeated demonstration, testing and comparison.The Hong Kong Zhuhai Macao bridge crosses the Pearl River Estuary and Lingdingyang sea area, which also means that all LED products and systems on the bridge need to withstand the harsh environment such as severe marine salt fog attack, vibration, large temperature difference, typhoon and thunderstorm on the basis of ensuring energy conservation, efficiency, safety and comfort.Shanghai Sansi said that the LED street lamps of Hong Kong Zhuhai Macao Bridge adopt ceramic radiator and honeycomb convection heat dissipation technology. The technology was selected into the 2015 national key energy-saving and low-carbon technology promotion catalogue. There are no non-ferrous metals. Independent pixels disperse heat dissipation, and the heat loss is more complete. It can adapt to the multi vibration and multi salt fog environment of the sea crossing bridge at the same time, with pressure resistance and corrosion resistance, so that the service life and reliability have been qualitatively improved.The LED tunnel light adopts reflective LED technology, which can not see the light, and the light is uniform, soft and not dazzling. The technology comes from the LED tunnel lighting standardization demonstration project of Shanghai Construction and Communications Commission - Shanghai Dalian Road Tunnel Lighting reconstruction project.The LED variable information board used in the Hong Kong Zhuhai Macao Bridge project this time also adopts a number of new technologies and materials against salt fog, vibration, ultraviolet and high and low temperature to fully ensure the operation of traffic information release and traffic guidance functions while ensuring the original technical advantages.Philips dynamic LED lighting is adopted for the largest cable-stayed bridge in AfricaThe largest cable-stayed bridge in Africa, the cable-stayed bridge in the briglig valley of the kingdom of Morocco, was officially completed and opened to traffic at 15:00 local time on July 7 (23:00 Beijing time on July 7). The cable-stayed bridge adopts dynamic LED lighting of Philips Lighting. The colors of LED lamps used vary up to 16 million.Briglig cable-stayed bridge has a total length of 952m and a total deck width of 30.4m. The main bridge adopts (183 376 183) m composite beam cable-stayed bridge, and the main tower adopts four limb separated space curve concrete structure; The main beam adopts the side main beam structure, the concrete side main beams are connected through steel beams, the precast concrete bridge deck is installed on the steel beams, and the expanded foundation is adopted for the main tower pier. The approach bridge is a 5-span 40m precast T-beam structure. The main tower design of the bridge is unique and the main beam design is simple. Among the similar cable-stayed bridges in the world, the flexibility and span are the first in the world.The highlight of the bridge design is the two main towers. The main tower adopts a beautiful diamond structure shape, which extends upward from the bottom and gradually opens in an arc. It is gradually divided into four branches in the middle and integrated at the top of the tower. Its design has typical Arab architectural characteristics and the moral of "victory gate" and "ideal gate".The cable-stayed bridge has become a new landmark in Rabat and a landmark in Morocco. Muhammad VI bridge adopts unique architectural design and Philips color dynamics technology to create a beautiful perspective effect. The LED lighting system is expected to save 75% energy consumption than the traditional lighting system.There is no doubt that led technology is developing rapidly and will replace the traditional light source as the main lighting means sooner or later. LED has played a great role in adding light and color to the urban lighting project. For bridge landscape lighting, reasonable and correct selection of lighting mode is not only a good unity of economy and practicability, but also an important content to realize "green lighting".

Very very rarely, maybe one in a million devices will have a faulty battery. So it's not a big issue.1. Why does the battery of a phone drain when kept switched off?Cell phones constantly use power to "Call Home" to the nearest cell tower to say where they are. They do not do this when they are OFF.We live in a rural area with minimal cell reception, and the need for the cell phone to go to full power (when it's ON) for this internal communication, drains the battery. (It's just sitting there in ON - we are not talking, or calling, or receiving a call). So, we keep the phone OFF when it's at home (preserving the battery charge); and only turn it ON when we are in town (with it's lots of cell towers). The battery power consumed in populated areas, when it's ON but dark may be minimal - but in rural areas, it sucks the battery dry to be left ON - even if there's a dark screen2. What happens if I keep my non-removable battery phone unused for 6 months?THIS ANSWER IS GIVEN AFTER PRACTICAL EXPERIENCE ONLYNothing happens to your device or your battery at all, as i did not use my past phone the LENOVO ZUK Z1 after 1 year or above,when i restarted it was working perfectly and the battery performance was still the same even after 1 whole year and i was very happy about it so this was the only proof to say that nothing happens to your device even you keep it unused for yearsWhat happens if I keep my non-removable battery phone unused for 6 months?3. Do counterfeit wireless chargers affect the phoneu2019s battery or the phone generally?I suppose a fake charger won't charge the battery and therefore do NOT affect the battery.By fake I assume you mean a charger that is not really a charger (i.e. a dummy) as opposed to being a non-phone branded generic charger. Do counterfeit wireless chargers affect the phone's battery or the phone generally?Do fake wireless chargers affect the phone's battery or the phone generally?4. Can I charge a battery and a phone at the same time? [closed]I've looked at several battery manufacturers comments and they generally say NOT to do this. If you think about this - if you are charging at 1 amp and at the same time pushing out 1 amp to a downstream device, how can the battery ever charge at all? That also does not consider the inefficiencies of the design. Generally the efficiency is supposed to be something like 35% so only 35% of the battery's charge could go downstream and I am not sure of what the charge efficiency is.5. I use my iPhone most of the time while charging to text and play iMessage games. Does it damage my battery or the phone? I checked my battery health and it's fine.Thanks for the A2A.As Chris Summers said, if your phone heats up to the point it is uncomfortable to hold, it's time to put it down and let it charge up. Otherwise, you are not harming your battery.Your iPhone is very good at managing its own battery so except for the heating up issue, you want to keep it plugged in as much as possible to minimize the number of charging cycles it uses. This will increase the battery's productive life overall6. Does helping a boyfriend buy a new car battery and phone mean i'm helpful or a pushover?I do not think you are a pushover. If the baby is his you are locked for life anyway. You need to go to monster/indeed/careerbuilder wewbsites and type in entry level account executive. There are tons of jobs for newbies and it's a great start to any career, plus they always in most circumstances offer salary. Good luck.7. Can I charge my Moto G5 Plus with a charger of 2.8A without damaging the battery or the phone?The short answer is no, it won't damage the phone as long as the charger is of the proper type (USB) and voltage 5ish volts.The current listed on the charger is the maximum current/power that it is designed to supply, the phone or device being charged will only take the amount that it needs/can use to run itself and charge the battery.As a bonus the phone might charge a little faster if the old charger didn't put out at least as much current/power that the phone or device being charged could use. If a charger is smaller than what is needed, then it will take longer to charge, if the charger cannot supply enough power to run the phone or device alone, then the battery won't charge or may even discharge even though it's plugged in...I hope you found this info to be useful/helpful.Can I charge my Moto G5 Plus with a charger of 2.8A without damaging the battery or the phone?.
Can Boiling Water Purify It? What's a Good Water Medium Sized Water Filter?
Can Boiling Water Purify It? What's a Good Water Medium Sized Water Filter?
Boiling kills most microorganisms. It may or may not help with the taste. They SHOULD test your water without charge to you. Once the water is tested, the provider might correct the problem or tell you what you have to do to correct it yourself. It depends on where the problem is. In the meantime, try running your drinking water through a carbon filter, like the Brita.1. How do you make an emergency water filter and purifier?Much like Charlie's gravity filter in a bottle, this filter is essentially the same, only using a cone of tree bark in place of the bottle, and using extra filtration layers instead of a coffee filter or bit of cloth:Using a shirt, or bag with a hole in the bottom, or whatever bits of material you can spare, you can set up a tripod filter as shown below: Images: Pinterest, of all places...These filters appear to only be effective at cleaning the water of dirt and debris, boiling the water is still recommended for purifying the water and killing anything that might make it through your filter, though any poisons should be mostly absorbed by the charcoal.What remains to be discovered is what could potentially be used in either of these systems to purify the water as much as possible without boiling. The following are layers you can include in your filter, and what they accomplish:2. black stuff in brita water filter?If you read the instructions, you would know that you have to rinse the filter a lot before using it. The black stuff is just carbon, it wo not kill you3. What happens if you run milk through a pur or brita water filter?You get a dirty Brita filter that needs replacing4. What's better, Brita Faucet-Mount Water Filter or the Pitcher Water Filter or do thy work the same?lol, i had both. double filtered my water. The faucet one, it was HUGE. but it did work well. The pitcher I just had to toss because the kids forgot to refill it. It ended up kinda smelly. Go with the faucet.5. M17A2 gas mask does water filter?Ok dude here is the deal. I was in the Marine Corps for 6 years in the Infantry. The Gas mask has a carbon filter which does not filter the water. Like the other guy said there is a drinking tube that is folded up in where the one way valves are that let the air out and not let air in. What he did not tell you is that the drinking tube only hooks up to a Standard issued canteen. there is a cover or supposed to be a cover on the very top of the canteen which covers a hole and plastic that hooks up to the drinking tube. You hook it up and then turn the canteen over and gravity pushes the water into the tube and you drink it. I have done this so many times in the gas chamber with tear gas pellets. I was in charge of my Battalion getting Gassed. Oh and by the way just hope you never run into something other than tear gas with those masks because most of the chemicals weapons that would be used, well the carbon in the filters will melt and not work as little as 20min to 2 hours. Now that is good because it gives you a chance to get out of the "Kill Zone" but most of the weapons do not just come down and drop gas they explode and then release the gas, chemical, or nerve agent. Hope that helps6. Is there an expiry date for Brita water filter?I had mine for 2 years--- I would exchange it every two years or 1.5 years (:7. I want to set up a water filter for my kitchen sink.?First off I've been doing water treatment for 13 years. if your water is 33 grains hard a filter will barely help. The most you will hope to accomplish is having better tasting water with a carbon filter. You really need to start with a water softener. I would recommend Kinetico brand units the best by far. Your ice is bad because of the minerals being trapped in the ice. The minerals will not be caught by an in line filter. Its like expecting the color of Kool-aid to go away by pouring it through a T-Shirt. The hardness will need to be removed by a chemical reaction with what is inside the softener. (do not be frightened its not actually chemical its called ion exchange) If you are concerned about the water i would add a R.O. system (reverse osmosis) Use this for all your cooking and drinking. It is great water. Again 13 years If you still just want a filter I would go with one you mount under your sink and can change it by unscrewing a standardized canister. Do not get one that uses a specialized proprietary filter, unless they are really special they normally just do that to get your money. Some however do more than just filter. Good luck and do your homework.
Precautions for Installation of Liquid Vortex Flowmeter
Precautions for Installation of Liquid Vortex Flowmeter
The installation of liquid vortex flowmeter shall consider the positioning of flowmeter, liquid flow direction, length of upstream and downstream visual sections, piping diameter, environmental impact (temperature, electromagnetic radiation, corrosion), vibration, valve installation, pipeline support and other factors. Generally, the flow diameter and piping diameter shall be consistent and concentric. The length of upstream straight pipe section usually depends on the form of upstream resistance parts (pipe shrinkage, expansion, elbow and valve). Generally, the length of upstream straight pipe section shall be 20d and downstream 5D (where D is the pipe diameter). When the upstream resistance part is a valve or stop valve, the length of the upstream straight pipe section must be no less than 40d. The installation site of flowmeter shall avoid high temperature, corrosion, electromagnetic radiation and vibration source. When the vibration is strong, support shall also be considered to reduce the impact of amplitude. When the liquid vortex flowmeter is used for control loop measurement, it is recommended to install the flowmeter downstream of the regulating valve.Generally, in order to avoid vibration or some unpredictable reasons, a throttle ring, expansion section or storage tank are installed upstream of the flowmeter to partially absorb the vibration and impact of the fluid, which is particularly important in the control circuit. If the vibration in a certain direction is predicted, the liquid vortex flowmeter shall not be installed where the vortex lift direction is consistent with the vibration direction.When the liquid vortex flowmeter is installed in the horizontal pipeline, the ultrasonic probe shall be in the middle of both sides of the horizontal pipeline (i.e. the vortex generator is in the vertical position up and down). In this way, bubbles are easy to gather above the pipe, and large foreign matters flow along the bottom of the pipe, which will hinder the ultrasonic passing through. If installed in the above way, the above phenomena are effectively avoided and bring benefits to the measurement.
