Problems solved by technology

[0004] The above-mentioned conventional diode light sources all have the following disadvantages: the external electro-optical conversion efficiency of the light-emitting diode is 30-40%, the white light luminous efficiency is 120-170lm / W, and the light efficiency is low
However, the packaging structure of this light-emitting diode light source emits light from one side and has side-lighting dead angles, which cannot meet the needs of four-sided light-emitting lighting fixtures without dead angles, and the phosphors and light-emitting diodes are not completely sealed in the substrate, which is unsafe. Hidden danger
