Problems solved by technology

In the above two methods, the heat conduction path from the LED chip to the radiator is too large, resulting in a large thermal resistance, and the heat of the LED chip cannot be effectively dissipated in a timely manner.
[0003] The LED bulb lamp with the above structure has a large thermal resistance between the light source component and the heat sink component, so that the heat generated by the LED light source component cannot be dissipated in time, resulting in a high junction temperature of the LED chip. The higher the temperature of the chip, the faster the decay of the LED chip, so the life of the entire LED bulb is shorter

Description

technical field [0001] The invention belongs to the technical field of lighting devices, and in particular relates to a light source and radiator integrated lamp and a manufacturing method thereof. Background technique [0002] Current lamps, such as LED bulb lamps, are mostly composed of a lamp cap assembly, a power supply assembly, a radiator assembly, a light source assembly, a lampshade, and the like. Most of the existing LED bulbs use SMD light sources or light source modules; if SMD light sources are used, the thermal resistance between the LED chip and the radiator is determined by the thermal resistance of the light source components, the thermal resistance generated by the solder paste, and the light source substrate. The thermal resistance generated by the thermal resistance, the thermal resistance generated by the heat-conducting material, etc.; if the light source module is used, the thermal resistance between the LED chip and the heat sink is composed of the the...
