Abstract

The invention discloses an LED bulb which comprises a cap, a cap plastic part, a glass core, an envelope, a plurality of LED filaments and a socket. The cap plastic part is connected with the cap, the glass core is connected with the cap plastic part, the envelope is connected with the glass core tightly, the LED filaments are disposed in the envelope, the socket is connected with the upper end of the glass core, and the LED filaments are inserted to the socket. The socket comprises a socket base plate with a plurality of connection holes and also comprises a plurality of sub sockets matched with the connection holes, and the LED filaments are inserted to the sub sockets. The included angles between the LED filaments and the plane of the socket base plate are smaller than 90 degrees. Since the LED filaments are fixed in an inserted manner, various defects in welding process in the prior art are overcome, and quick and reliable assembling can be achieved. Since the included angles between the LED filaments and the plane of the socket base plate are smaller than 90 degrees, the light distribution effect of lamps is improved.

Description

technical field [0001] The present invention relates to the technical field of LED (Light Emitting Diode, light emitting diode) lamps, and more specifically relates to an LED light bulb. Background technique [0002] LED light sources are gradually replacing light sources such as incandescent lamps and fluorescent lamps with the characteristics of long life, no pollution, and high luminous efficiency. Therefore, light bulbs using LEDs as light sources have appeared. LED light bulbs in the prior art generally include a lamp cap, a lampshade and an LED light source fixed in the lampshade. The LED light source includes several LED filaments, and the several LED filaments are fixed by welding and positioning. Fixing the LED filament by welding has many defects, such as the LED filament is relatively thin, the welding pad is small, and welding is difficult, thereby reducing production efficiency. The high temperature generated during the soldering process can also adversely aff...
