Problems solved by technology

[0002] The light source used in the traditional new LED lamp tube is usually a point light source, which has the defects of dazzling light and insufficient brightness, and the heat dissipation effect of this kind of lamp tube is poor, and the heat emitted by the LED light source cannot be dissipated in time, which seriously affects The service life of the new LED lamp tube also restricts the increase of the power of the lamp tube with this structure. Moreover, the constant current drive power supply of the traditional new LED lamp tube is external, which occupies a certain installation space of the lamp tube, which is not convenient for the lamp tube assembly

Abstract

The invention discloses an LED lighting tube which comprises a light source, a lamp head and an LED driving constant-current power source. The light source is an LED lighting panel which is attached to a sectional sheet support, and a radiating part and a power source box are mounted on the sectional sheet support; the LED driving constant-current power source is arranged in the power source box, a diffuser cover is mounted on the sectional sheet support, and the radiating part and the power source box are fixed on the sectional sheet support by the lamp head. The LED lighting tube can send out rays with soft diffusion as a traditional T8 fluorescent lamp, overcomes the glare lighting defect of an LED point light source, effectively solves the LED radiation problem, is beneficial to the improvement of the power and the service life of the lighting tube, favorably improves the light decline and the light efficiency of an LED, solves the problem that the T8 lighting tube is hard to internally arrange a power source, reduces a mounting space of the lighting tube, is convenient to mount the lighting tube and enables the LED T8 lighting tube to directly replace the traditional T8 fluorescent lamp.

Description

technical field [0001] The invention relates to an LED lamp tube, in particular to a T8 type LED lamp tube. Background technique [0002] The light source used in the traditional new LED lamp tube is usually a point light source, which has the defects of dazzling light and insufficient brightness, and the heat dissipation effect of this kind of lamp tube is poor, and the heat emitted by the LED light source cannot be dissipated in time, which seriously affects The service life of the new LED lamp tube also restricts the increase of the power of the lamp tube with this structure. Moreover, the constant current drive power supply of the traditional new LED lamp tube is external, which occupies a certain installation space of the lamp tube, which is not convenient for the lamp tube assembly. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides an LED lamp tube with high brightness, high power, good heat dis...
