Description

technical field

[0001] The invention relates to a lighting fixture, in particular to an LED lamp with an adjustable irradiation angle. Background technique

[0002] LED (Lighting Emitting Diode) is a light-emitting diode, which is a semiconductor fixed light-emitting device. It uses a solid semiconductor chip as a light-emitting material, and releases energy through the recombination of carriers in the semiconductor. The energy is emitted in the form of photons, thereby emitting light. , LED lighting fixtures use LEDs as light sources. In the context of the current global energy shortage, energy-saving LEDs have attracted people's attention.

[0003] As people's requirements for green lighting are getting higher and higher, LED lighting with many advantages such as low energy consumption, high luminous efficiency, and long service life has gradually replaced traditional fluorescent tubes and halogen lamps, and has begun to be widely used. At present, the existing lighting ...
