AI Technical Summary
The lighting intensity of traditional semiconductor lighting modules is fixed, resulting in the lighting brightness that cannot be controlled. When the traffic flow is high at night, the brightness is insufficient and it is inconvenient for pedestrians. However, when the traffic flow is too high, the brightness is likely to cause light pollution.
A semiconductor LED lighting module with light -adjustable light strength is designed. It uses the light sensitivity sensor and the driver motor to adjust the angle of the shading plate through the telescope of the wire rope to adjust the light strength.
The adjustment of the lighting of the light at different times at night is achieved, and light pollution is avoided. At the same time, the heat dissipation efficiency of the LED lamp head is improved through the air drawing machine and the heat dissipation structure.

They are an effective way to achieve energy conservation and emission reduction.
[0003] The light intensity of traditional semiconductor lighting modules is fixed, and the lighting brightness cannot be adjusted. This results in the street lamps with insufficient lighting brightness and range in areas with heavy traffic at night, which is inconvenient for pedestrians.

[0011] Compared with the prior art, the beneficial effects achieved by the utility model are:
[0012] The utility model provides a semiconductor LED lighting module with adjustable light intensity. When the light sensor senses that the brightness intensity of the outside world is large or small, the data detected by the light sensor is transmitted to the controller for analysis, and then the controller starts the driving motor, which drives the winding shaft to rotate, and drives the movable plate to rise or fall through the extension or relaxation of the wire rope, so that the roller set at the top of the movable plate rolls in the slide groove, thereby changing the angle of the sunshade, so that the sunshade can block the light and weaken the light intensity, thereby realizing the adjustment of the lighting brightness at different time periods at night, and it is not easy to cause light pollution;
