Problems solved by technology

[0002] Existing LED light bulbs are mainly composed of lamp caps, lamp holders, drivers, radiators, LED light source components, and light transmission covers. One is to use reflective devices for light distribution, and all heat is only dissipated through single-ended radiators. The disadvantage is that the heat dissipation area is small, the power cannot be increased, the total output luminous flux of LED bulbs is low, and the light loss of reflected light distribution is large, and the overall system efficiency is low.
Another kind of LED light bulb integrates the LED light source on a stem and places it in a closed bulb. The heat dissipation efficiency is extremely low, the LED power cannot be increased, and the overall light output of the LED is low, which is difficult to meet customer requirements.

Embodiment Construction

[0016] Such as figure 1 , figure 2 As shown, an LED light bulb is composed of a lamp cap 1, a lamp holder 2, a driver 3, a radiator 4, an LED light source assembly 5, a reflector 6, a translucent cover 7, and the like. The upper part of the radiator 4 has a plurality of multifaceted radiators, and the multifaceted radiator is a V-shaped radiator, the V-shaped mouth is towards the bulb outer edge direction, and the V-shaped bottom is towards the bulb axis direction. The lower half of the radiator 4 is provided with a hollow cooling cavity. The LED light source assembly 5 is a plurality of independent LED light source assemblies, which are respectively fixed on multiple multi-faceted radiators of the radiator 4, and the number of LED light source assemblies is equal to the number of multi-faceted radiators. In this embodiment, four LED light source assemblies 5 are respectively installed and fixed on four multi-faceted radiators of the radiator 4 . The heat generated by the ...
