Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an LED lamp with excellent heat dissipation performance. Background technique [0002] LED (Light Emitting Diode, Light Emitting Diode) is a solid-state semiconductor device that can convert electrical energy into visible light. LED has the characteristics of energy saving, environmental protection, long life, small size, etc., and can be widely used in various indications, displays, decorations, backlights, general lighting and urban night scenes and other fields. LED lamps have high requirements for heat dissipation. 70% of LED lamp failures are caused by untimely heat dissipation, and 90% of the heat generated by LEDs is diffused outward through conduction. At present, the key to the life of LED lamps is the quality of the light source and the heat dissipation effect of the whole lamp. It is urgent to develop high-performance heat dissipation materials. [0003] In terms o...
