How is the LED street lamp manufacturing

LED technology is a kind of very popular science and technology in recent years, its application in various fields, such as every building in the city lighting engineering, household household lighting projects, including road lighting it in one direction. The continuous development of LED lighting technology, brought new look for urban and rural road lighting. Below to introduce LED street lamp for everyone is how to make it.

solar lighting

the principle of the solar energy is a clean energy, it hits ranked on the solar cell array, can be converted into current through the diode, the electric current is transferred to the rechargeable battery and bulb of the flash device. During the day, the sun light is rich, can convert enough power for the light bulb flash device. When night came, solar stop transformation, electrical energy stored in the battery began lighting work can make the light bulb.

ordinary a light-emitting diode ( 领导) What's in the

it is controlled by the integrated circuit LM3909, and the integrated circuit is to be repeated on, repeat off diode is contained in all the circuit you need. A light emitting diode scintillation timing capacitor is 220 & mu; F capacitance.

there's a more simple flash device, the diode ( 领导) Consists of type CQX21 flashing light emitting diode, light emitting diode placed inside all the components, it needed to flash and CQX21 instead of the integrated circuit LM3909, capacitors, and ordinary light-emitting diodes (leds).

all in all, with the sun's rays, nickel cadmium battery, light emitting diode ( 领导) These three conditions, can make the LED street lamp manufacturing. If out of circuit nickel cadmium battery, so the LED street light only in the sun or a light to illuminate the battery only when working. In a sense, if you just want to by ordinary batteries, then remove the nickel cadmium battery at the same time and diode. But since so abundant solar energy resources, why give up such a high cost performance LED street light?
