Abstract

The invention discloses a light emitting diode (LED) fluorescent tube which comprises a power supply, a PC outer cover, a PCB, a radiator and plugs with long slopes. The inner wall of the PC cover is provided with an expansion component, and the outer wall of the PC cover is sleeved with a glass pipe. The radiator comprises a PCB mounting face and a light receiving face. Cooling teeth are mounted on the back of the PCB mounting face. The outer surface of the radiator is provided with lower fins. The surfaces of the plugs are provided with air convection holes symmetrically distributed up and down. The thickness of the fins is no larger than 10 mm. According to the LED fluorescent tube, dust cannot be accumulated on the surface of the radiator, effective air convection is formed, the service life of the product is long, and the production efficiency is high.

Description

technical field [0001] The invention relates to a fluorescent lamp tube, in particular to an LED fluorescent lamp tube. Background technique [0002] LED (Light-Emitting-Diode in Chinese means light-emitting diode) is a semiconductor that can convert electrical energy into light energy. It changes the principle of incandescent lamp tungsten filament luminescence and energy-saving lamp tri-based toner luminescence, and uses electric field luminescence. According to the analysis, the characteristics of LED are very obvious, such as low power consumption, high directivity, long life and adjustable light, small size and high color rendering. The spectrum of LED is almost all concentrated in the visible light band, and its luminous efficiency can exceed 150lm / W (2010). Compared with other traditional light sources, it has become inevitable for LEDs to be used as lighting products. At present, the LED lamp tubes on the market are generally round transparent or translucent PC cov...
