Abstract
The utility model discloses an LED tube lamp, and belongs to the field of energy-saving LED lamps. According to the technical scheme, the LED tube lamp comprises an LED drive power source, an aluminum outer shell and a reflection cup. The outer shell is internally provided with a lamp panel provided with a through hole. The LED tube lamp further comprises an LED substrate and a paster type LED lamp body. The front face of the LED substrate fixes the paster type LED lamp body, the back face of the LED substrate and the lamp panel are closely fixed, and the back face of the LED substrate is provided with a heat conduction layer. Due to the fact that the back face of the LED substrate is provided with the heat conduction layer, the heat conduction layer makes contact with the lamp panel in the outer shell, the heat dissipation performance of the tube lamp is improved, the work temperature of the LED tube lamp is smaller than 60 DEG C, and in addition, due to the improvement of the heat dissipation performance, the power of an original LED tube lamp with the power ranging from 40 W to 50 W can reach to 60-70 W under the same appearance size. The tube lamp is produced with the technology.
Description
Technical field
