Problems solved by technology

Generally, high-power LED equipment used for lighting only has two states of lighting and extinguishing. As long as it is turned on, it will work at the rated maximum power and will not change its illuminance with changes in the external environment, which causes a waste of energy.

At the same time, the input power is proportional to the temperature of the LED. Continuous work at the rated maximum power will inevitably cause the LED lighting equipment to be in a high temperature working state for a long time.

[0005] Therefore, during the implementation of the present invention, the inventors have discovered the following problems in the current prior art: the existing high-power LED lighting equipment cannot change the working state with the change of the external environment, resulting in a waste of energy; The rated maximum power will inevitably cause LED lighting equipment to work at high temperature for a long time, which will seriously affect the service life of the equipment
