Problems solved by technology

Due to the current low electro-optical conversion efficiency of LEDs, a large amount of heat is generated. If the heat is not removed in time, it will aggravate the light decay of the light source and affect the service life of LEDs.
[0003] At present, most of the thermal conductive adhesives are used to solve the heat dissipation problem of LED lamps, but the materials used have technical problems such as poor temperature resistance and aging resistance, low adhesion to the substrate, poor heat dissipation effect and inconvenient operation, which are difficult to meet people's expectations. Requirements for heat dissipation of LED lamps

Description

technical field [0001] The invention relates to the technical field of LED lighting coatings, in particular to a preparation method of an environmentally friendly flame-retardant LED heat dissipation coating. Background technique [0002] LED (Light Emitting Diode) has been rapidly developed due to its high luminous efficiency and low power consumption. LED lighting technology has the advantages of high light efficiency, energy saving and environmental protection, and long service life. It has been widely used in indoor lighting, traffic lighting, display, decoration and other fields. Due to the current low electro-optic conversion efficiency of LEDs, a large amount of heat is generated. If the heat is not removed in time, it will aggravate the light decay of the light source and affect the service life of LEDs. [0003] At present, most of the thermal conductive adhesives are used to solve the heat dissipation problem of LED lamps, but the materials used have technical pro...
