AI Technical Summary

Problems solved by technology

As the thickness increases, its thermal conductivity will drop significantly, which cannot solve the contradiction between thermal conductivity and insulation well.

Even if the thinner ceramic-based insulating sheet 304 can meet the high-voltage resistance requirements, because the thermal conductivity of the ceramic-based insulating sheet 304 in the horizontal direction is very poor, it is necessary to use a metal-based heat dissipation component 305 with an area substantially equal to that of the ceramic-based insulating sheet 304 , resulting in the whole structure becoming very bulky, not only adding weight but also wasting material

[0009] The above-mentioned widely used structures of various LED bulbs cannot solve the contradiction between heat conduction and insulation, cannot solve the contradiction between heat conduction, insulation and lamp body weight, and cannot solve the contradiction between heat conduction and high temperature resistance, high voltage resistance, antistatic, anti-ultraviolet The contradiction between light irradiation cannot solve the contradiction between the heat conduction and heat dissipation components and the contact area of ​​the lamp board
