Problems solved by technology

[0004] figure 2 What is shown is the second power supply structure of the existing LED lamp tube, in which the driver for driving the LED lamp bead 13 is combined with the PCB lamp board 12. This kind of LED lamp tube usually does not use the aluminum shell 10 for heat dissipation. Compared with the aforementioned first power supply structure, the use of the aluminum housing 10 with the supporting surface 101 can reduce the manufacturing cost of the LED lamp tube, but the poor heat dissipation capability will affect the service life of the LED lamp tube

Abstract

The invention provides an LED lamp tube. The LED lamp tube comprises a light-transmitting lamp tube, an LED driver and an LED lamp panel; plugs are fixedly installed at the two ends of the light-transmitting lamp tube, the LED driver is installed in the plugs and electrically connected with contact pins of the plugs; the LED lamp panel comprises a base material, at least one LED lamp bead and a conductive circuit, wherein the LED lamp beads are fixed to the first surface of the base material and electrically connected with the LED driver through the conductive circuit. The LED driver is used for converting an external power supply into electric power used for driving the LED lamp beads to emit light, and the second surface of the base material is provided with a heat conduction metal and is connected with a metal wire on the first surface, so that heat of the LED lamp beads can be directly transmitted to the heat conduction metal on the second surface of the base material through the metal wire on the first surface; the second surface of the base material and the heat conduction metal on the second surface are coated with heat conduction and dissipation glue, and the LED lamp panelis pasted and fixed to the surface of the inner side of the light-transmitting lamp tube through the heat conduction and dissipation glue.

Description

technical field [0001] The invention relates to an LED lighting device, in particular to an LED lamp tube. Background technique [0002] Light-emitting diode lighting technology refers to the technology that uses light-emitting diode (LED) as the lighting source. In recent years, due to the substantial progress of light-emitting diode manufacturing technology, especially high-power, high-brightness white light-emitting diodes have been successfully developed. Completed, based on the ideal of green energy and environmental protection, LED tubes (LED tubes) using light-emitting diodes as light-emitting components have begun to appear on the market, and may replace traditional fluorescent tubes (fluorescent tubes) in the future. [0003] figure 1 It is a cross-sectional view of the structure of an LED light tube sold in the existing market, basically including: a semicircular aluminum shell 10, a PC light-transmitting cover 11 and a PCB light board 12; the front configuration ...
