Lithium battery solar street light has entered our life, we usually see the solar street light at night, how many hours later or at dawn when the active closure. This is the lithium battery solar street lamp controller in control, its control chip is embedded inside the street lamp, intelligent control street lamp on and off chip, commensurate with all the lithium battery solar street lamp brain. So, what is the regulation method and composition structure of lithium battery solar street lamp controller? The company's technicians answer for you:
I. Three regulation methods:
1, time control: it is important to use the time program to control the lamp on and off. This method was used more often in the early days, but less often at the beginning. The important reason is that different seasons in the same area will produce changes, and it is not convenient to choose time control.
2, light control: it is important to sense the strength of the external light through the panel, when the light reaches the set darkness, it will take the initiative to power the LED light source, when the external light reaches the set brightness, it burns the solar lamp. As for the brightness value, it can be manually changed. Most solar street lamps used this method.
3, light control + time control: it is important to sense the strength of the external light through the panel. When the light reaches the set darkness, it will take the initiative to energize the LED light source, and then control the solar street lamp by setting the time to turn off the light
Two, what parts of the controller:
1. Hardware: the combination of individual circuit boards and chips. LED street lamp it is a kind of efficient solid state light source based on semiconductor PN junction formed with weak electric energy can emit light, in a certain forward bias voltage and injection current, injected into the hole in the P region and injected into the N region of electrons in the diffusion to the active region after radiation compound and emit photons, the electric energy directly into light energy. It is a solid cold light source, with environmental protection, no pollution, less power consumption, high light efficiency, long life and other characteristics, therefore, LED street lighting will become the best choice for energy-saving transformation.
2, software: different solar lamp design details of different control software. Solar street lamp LED lamp head wire lithium control battery white cap separated, wiring attention to use electrical tape wrap.
The above is the control method and composition structure of the lithium battery solar street lamp introduced by solar lighting. It can be seen that our lithium battery solar street lamp is usually intelligent. The solar street lamp chip is a very important part, which often affects the luminous duration and the convenience of using. The wiring on the back of the solar panel is reverse buckle design, which can be gently pried open with a screwdriver. The wiring of the solar panel (red cap is connected to the positive pole line, black cap is connected to the negative pole line) corresponding to the positive and negative pole line separated from the black cap of the lithium integrated battery, and the wiring should be wrapped with electrical tape.
