Abstract

The invention discloses an LED light bulb, which comprises an LED, a base and a lampshade on the base, a reflector is arranged inside the lampshade, a layer of heat dissipation shell is arranged on the inner side of the reflector, and the bottom of the heat dissipation shell is fixedly connected with the base. There is an opening on the top to form a heat dissipation channel; there are at least two LEDs, which are fixed to the bottom of the heat dissipation shell through a heat dissipation plate, and the LEDs are evenly distributed circumferentially between the lampshade and the reflector; the lower side wall of the base is provided with There is at least one vent, and the vent communicates with the heat dissipation channel. The invention has excellent heat dissipation effect and greatly improves the service life of the bulb.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a light bulb with a light emitting diode (LED) as a light source. Background technique [0002] At present, the light sources used in indoor lighting fixtures such as desk lamps are basically incandescent bulbs or fluorescent tubes. However, the electric-to-optical conversion efficiency of incandescent light bulbs or fluorescent tubes is relatively low, and their heat generation is large and their service life is short. [0003] As an emerging semiconductor light-emitting device, LED has the advantages of small size, low heat generation, low power consumption, and long life. Therefore, some lamps using LED as light source have appeared on the market. Most of the existing LED lamps are composed of a lampshade directly sheathed on the periphery of the LED base, which not only affects the light output efficiency of the LED, but also has poor heat dissipation effect, which greatly affects the s...
