Description

technical field [0001] The invention relates to a high-efficiency and energy-saving LED lamp holder, which has low heat loss and high light efficiency. Especially a kind of lighting equipment that can intelligently adjust and control the road light illumination according to the traffic flow, traffic density and illuminance on the road. In the case of few people in the middle of the night, it can reduce the light illuminance and reduce the energy consumption of street lamps. At this time, if the road surface When there are pedestrians, vehicles or other moving objects, the lights can automatically restore full brightness or change to an artificially set illuminance. The lamp head of the LED street lamp has the functions of anti-theft and anti-destruction, and has the function of automatic switch on and off alternately day and night, and the switch lamp time can also be set through the network. Background technique [0002] So far, humans have inven...

Problems solved by technology

Another example is the sodium lamp widely used in street lamps in our country. It must be equipped with a rectifier to start, which consumes a large amount of non-ferrous metals. The collection, refining and use of non-ferrous metals will seriously pollute the environment. Moreover, the current high-pressure sodium lamps still have obvious electromagnetic pollution and noise pollution during use.

[0013] To sum up, most of the street lamp holders currently used in my country have many problems such as large power consumption, easy damage, short life, electromagnetic interference, noise, heat radiation, environmental pollution, etc.

Moreover, many street lamps keep a constant brightness since they are turned on, and cannot adjust and change the illumination according to environmental requirements, which consumes a lot of energy and is not conducive to environmental protection.

Even if some street lamps are equipped with a control system, they can only mechanically control and adjust the brightness in different periods. During the low-light period, the brightness of the lights cannot be adjusted in time according to the needs of the flow of people and traffic on the road, which causes inconvenience to people's lives.
