Problems solved by technology

[0005] Before filing this application, the inventor has studied the luminous efficiency and luminous angle of the existing LED bulb lamps and tested them, and found that the luminescence caused by the diffusion device or light mixing device of the existing LED bulb lamps The angles are limited by the material composition or structure of the light mixing cover or similar light-transmitting elements, and it is impossible to exceed the maximum 220° emitting angle and achieve uniform scattering of light, so it is necessary to add two more between the LED light source and the light mixing cover. Sub-optical design has achieved the purpose of increasing the beam angle
However, increasing the secondary optical design will inevitably increase the light loss, thereby reducing the light extraction efficiency of the LED bulb lamp
