[0002] As the global energy crisis and environmental pollution become increasingly serious, people have put forward higher requirements for the energy-saving and environmental protection performance of lighting fixtures. LED lamps have become an ideal choice to replace traditional lighting fixtures with their high efficiency, energy saving and environmental protection.

[0003] When the high-power LED light-emitting unit of an existing LED lamp holder is working, a lot of heat will be generated inside it. If the heat dissipation performance is not efficient enough, the heat will accumulate inside the LED light-emitting unit, causing the overall temperature of the lamp holder to rise. Excessively high operating temperature will cause the LED light-emitting efficiency to decrease, affecting the lighting effect, and will also accelerate the aging process of the LED light-emitting unit and shorten its service life. In addition, the irradiation angle of the existing LED light-emitting unit is fixed and cannot be flexibly adjusted according to actual needs, which will limit the flexibility and applicability of the LED light-emitting unit in different application scenarios.
