Abstract:
This invention discloses a LED light with omnidirectional light distribution comprising a light-emitting bulb and a lamp holder connecting with the light-emitting bulb. The lamp holder is set with a power driver, and external thread is set outside the lamp holder. The light-emitting bulb comprises a shell, a stem set inside the shell and a light-emitting component. One end of the stem is connected with the said power driver, and the other end of the stem is connected with the light-emitting component. The said stem is set with the wire. The angle between bar-type LED filaments is adjusted by changing the set height of support pillar and the sectional area of magnetic connecting piece, and the distribution curve fluxes of bar-type LED filaments are adjusted to obtain the LED lights with different distribution curve fluxes and make them meet different use requirements. The electrode of bar-type LED filament is connected with the wire by spot welding. The magnetic connecting piece adsorbs the die bond substrate through magnetic force to reduce the frequency of spot welding during production of LED lights with omnidirectional light distribution and greatly improve productivity and yield rate of LED lights.
