Abstract
The utility model discloses an LED lamp tube comprising a drive circuit, an LED light source module and lamp bases. The LED light source module comprises an arc-shaped reflection piece, a round glass lamp cover, an LED copper substrate and an LED lamp. The outer diameter of the round glass lamp cover is 32cm, and the inner diameter of the round glass lamp cover is 30cm. The LED lamp tube is ingenious and reasonable in structural design. A constant-current stabilizing output unit in the drive circuit is arranged on one lamp base, and a rectification filtering unit in the drive circuit is arranged on the other lamp base, so that the over-temperature problem is effectively solved and normal use of the LED lamp tube is guaranteed. Besides, the lamp bases are provided with heat dissipating holes which accelerate air circulation and can rapidly dissipate heat generated by the LED light source module and the drive circuit. Therefore, the heat dissipation problem of a high-power LED is thoroughly solved. The speed of luminous decay is slowed down and the service life is prolonged. Besides, the LED lamp tube is simple in structure, easy to use, capable of meeting the standards of low carbon and energy conservation of China on the basis of reduction of production cost, and is beneficial for wide popularization and application.
