Problems solved by technology
The disadvantages of this assembly are as follows: ①If the thermal paste is applied unevenly during the assembly process, the silicone thermal pad is uneven, or the aluminum-based circuit board is deformed, etc., the heat will not be exported in time and the service life of the fluorescent tube will be affected; ②Because the thermal conductivity of each object is different and when the two objects are in contact, there will be a gap between the contact surfaces, which affects the rapid conduction of heat
The above-mentioned conditions will occur between the LED lamp and the circuit board, and between the circuit board and the lamp housing, which will affect the service life of the fluorescent tube.

Description
technical field [0001] The invention relates to a fluorescent lamp tube, in particular to an integrated LED fluorescent lamp tube. Background technique [0002] At present, the general printed circuit board circuit design uses FR4 (glass fiber epoxy substrate) as the base material, and the circuit board is separated from the bottom case of the fluorescent tube. During the assembly process, the circuit board and the bottom case must be Apply thermal paste or add thermal silicone pads to quickly conduct heat to the lamp housing. The disadvantages of this assembly are as follows: ①If the thermal paste is applied unevenly during the assembly process, the silicone thermal pad is uneven, or the aluminum-based circuit board is deformed, etc., the heat will not be exported in time and the service life of the fluorescent tube will be affected; ②Because the thermal conductivity of each object is different and when two objects are in contact, there will be a gap between the contact su...
