There Are so Many Well-known Brands of Solar Street Lamps, How Should We Choose Manufacturers

Nowadays, solar street lamps have gradually penetrated into everyone's daily life, from both sides of municipal roads to ecological parks, from rural roads to the corners of streets and alleys. Solar street lamp is a key component of infrastructure construction in large cities and villages.

Solar street lamp manufacturers give prices to customers, and price fluctuations must be effective. However, at this stage, the vicious price competition of such prices is that some solar street lamp manufacturers give up product quality as the cost. The street lamp commodities at the base price are shoddy and apply fake and shoddy components. Therefore, problems will continue to occur in the whole process of commodity application, which will give customers a headache. Therefore, it is very important to select a good solar street lamp brand. Well-known solar street lamp manufacturers will give stronger product quality and service items. Today, our group has two large and medium-sized centralized manufacturing industrial bases. Today's achievements are not only the result of technological innovation and extraordinary quality, but also the result of our common boat, dream and efforts.

It's a long journey, but we still have a dream for a horse and don't lose our youth. Intelligence is an improvement of intelligence, which reflects a desire for intelligent commodity system, information management, high quality and high efficiency. We will forge ahead on the road of solar street lamps and become a well-known brand of solar street lamps selected by customers with peace of mind and sincerity.

Multi Channel Laser Anti-theft Alarm Circuit
The figure shows the circuit of multi-channel laser anti-theft alarm. VT1, vt2, RL1, RP1, R1, K and vd6 constitute an optical control switch. During the day, the photoresistor RL1 is in a low resistance state under light, VT1 is saturated on, vt2 is off, relay K is not energized, normally open contact J is off, and the alarm circuit does not work; At night, RL1 changes to high resistance state, VT1 is cut off, vt2 is saturated and turned on, K is powered on to make j pull in, the circuit supplies power to the whole machine, the red LED is on, the regulated voltage is 6V, and supplies power to the subsequent circuit after voltage reduction by vd7, vd8 and vd9. Laser rods JB1, RL2, VT3, RP2, R3 and R4 form a laser transmitting and receiving network. When the alarm is in the waiting state, the laser rod emits red laser and irradiates it on the photoresist RL2. RL2 is in a low resistance state, and the base potential of VT3 is very low, which provides trigger current for thyristor vs, vs is turned on, IC2 is powered on, and the horn gives an alarm sound. The alarm can be equipped with up to 10 laser transmitting and receiving networks at the same time. The circuit structure is exactly the same, and C3 is an anti-interference capacitor. An is a reset switch. When the power grid is cut off or the gangster cuts off the power supply, the battery immediately supplies power to the whole machine, ensuring the reliability of the alarm device.Component selection: IC1 is voltage stabilizing integrated circuit 7806, and aluminum heat sink shall be added during use. IC2 is KD-9561 four sound chip, and the circuit is connected to the second sound selection terminal sel2 (fire truck alarm sound). The laser source is a red laser rod with voltage of 4.5V and power
