Description

The present invention relates to a lamp tube, and more particularly to an LED lamp tube used to replace a fluorescent lamp.

As shown in FIG. 1, the conventional LED lamp tube has structural members, such as the glass tube body 1a and the LED lamp assembly 2a. The LED lamp set 2a includes a circuit board 20a horizontally disposed in the tube body 10a, and a plurality of LED lamps 21a, that is, light-emitting diodes are provided on the surface facing the circuit board 20a. A circuit control unit 22a is provided on the upward surface, and is used to convert current and voltage suitable for use of the light emitting diode. In addition, a conductive end cap 10a is attached to each of the two end locations of the tube body 1a and electrically connected to the circuit board 20a, thereby forming an LED lamp tube composed of a plurality of light emitting diodes. Can be replaced.

However, in this type of LED lamp, the circuit control unit 22a is arranged at one side of the circuit board 20a due to the design structure of the electronic member arrangement, that is, concentrated on one end of the lamp tube 1a. The other electronic member is not disposed at the other end. In this way, although it is advantageous for the electronic members to be aligned, in the LED lamp tube, in actual use, the amount of heat is concentrated on the same side of the circuit board 20a, and the LED lamps on the side and the vicinity thereof are concentrated. The LED lamp 21a in this part has a serious defect that shortens its service life because the heat sink effect is deteriorated, the LED lamp 21a is damaged early, and the entire LED lamp tube needs to be replaced. The LED lamp 21a that has not reached the end of its life is wasted.
