Abstract
The instant disclosure relates to a light bulb, which includes a base, a conducting cap arranged on one end of the base, a heat-dissipating member disposed on the opposite end of the base, and a lamp cover. The heat-dissipating member has a wedged structure, and a plurality of inclined surfaces are formed adjacently thereon. A plurality of LEDs is disposed on the inclined surfaces, and the lamp cover is arranged over the wedged structure and the LEDs. The instant disclosure uses the LEDs to replace tungsten filament as the light sources, and arranging the LEDs on the wedged structure of the heat-dissipating member. Thereby, the light bulb can have higher heat-dissipating rate.
