Abstract
The LED lighting device includes a tubular housing, a light emitting unit, and a reflector. The tubular housing has an accommodating space. The light emitting unit is disposed in the accommodating space and has a plurality of light emitting diodes. The reflector is disposed in the accommodating space and has a wing-shaped reflecting portion. The reflecting portion faces the light emitting unit for reflecting the light source emitted from the light emitting diodes to the lateral directions of the tubular housing. As a result, the light source can be converted to a specific direction. Compare to the fluorescent lamps, the present invention has higher illumination efficiency and a longer operating life. The volume of the lamps and the cost are saved.
