Description

Technical Field

[0001] This utility model relates to the field of lighting, specifically an LED lighting fixture with high heat dissipation performance. Background Technology

[0002] LED lighting fixtures are widely used in various lighting fields due to their advantages such as energy saving, environmental friendliness, and long lifespan. However, LEDs generate heat during operation. If this heat cannot be dissipated in time, the LED chip temperature will rise, affecting its luminous efficiency and lifespan. Therefore, heat dissipation performance is one of the key issues in the design of LED lighting fixtures.
