Light source circuit of white light diode solar pole light

Abstract

This invention relates to a white light diode solar street lamp lamp-house circuit, which is composed of the voltage-stabilization circuit, the driving circuit, the white diode pipe and the constant-current control circuit, the character is that the voltage-stabilization connects with the direct voltage Vcc and terra GND that out put from the intelligent switching device, the output of the voltage-stabilization connects with the driving circuit, the power auto control circuit connects with the driving circuit directly, and the output of the driving circuit connects with the constant-current control circuit, the positive pole of the white light diode connects with the direct voltage Vcc, and the negative pole of the white diode connects with the constant-current control circuit.

Description

Technical field: [0001] The invention relates to a road lighting device, in particular to a semiconductor white light diode solar street light source circuit. Background technique: [0002] At present, solar street lamps with single power supply and rare earth energy-saving light sources are available. Although solar energy-saving rare earth light sources have the advantages of lower energy consumption and longer life than incandescent light sources, compared with the new light source white light diode (LED), there is still energy consumption. High and short life defects. In addition, the use of solar energy storage is energy-saving and environmentally friendly, but it is greatly affected by the weather, and designers have to increase the area of ​​solar panels to make up for it. As a result, not only the cost increases, but also the brightness of the lamp caused by insufficient electricity storage is not really solved. The problem of instability or even "not turning on the...

[0002] At present, solar street lamps with single power supply and rare earth energy-saving light sources are available. Although solar energy-saving rare earth light sources have the advantages of lower energy consumption and longer life than incandescent light sources, compared with the new light source white light diode (LED), there is still energy consumption. Defects of high and short life

In addition, the use of solar energy storage is energy-saving and environmentally friendly, but it is greatly affected by the weather, and the designer has to increase the area of ​​the solar panel to make up for it. As a result, not only the cost increases, but also the brightness of the lamp caused by insufficient electricity storage is not really solved. The problem of instability or even "no lights" is not conducive to popularization and use
