LED bulb lamp

Abstract

The invention discloses an LED bulb lamp which comprises an LED bulb lamp panel and a light processing structure. The LED bulb lamp panel is provided with at least one LED light source, and the light processing structure is arranged on the side, where the LED light sources are located, of the LED bulb lamp panel and is provided with a reflecting face used for changing the direction of light generated by the LED light sources. In this way, uniform transition of the luminance of the LED bulb lamp can be achieved, and the luminance can be distributed by more than 180 degrees; besides, production automation can be easily achieved; users can be prevented from being hurt; as the users can be prevented by through holes from making contact with internal electrified bodies under the condition that a lamp shell is broken, the electric shock risk is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of lighting devices, in particular to an LED bulb lamp. Background technique [0002] LED light sources have the advantages of long service life, small size, and environmental protection. However, due to the LED packaging bracket, the single light-emitting surface of the LED is relatively narrow. Generally, multiple or integrated COB light sources are integrated on the substrate, and the substrate also needs to block the light. The general LED bulb lamp needs to install the substrate with light source on the structure, resulting in the narrow light-emitting surface of the whole LED bulb lamp, presenting a half-circle light-emitting state, and the light distribution is less than 180 degrees. [0003] In order to have a light distribution similar to that of an incandescent lamp, the light distribution needs to be greater than 180 degrees. However, the existing general LED bulb lamps use COB integrated light...

AI Technical Summary

Problems solved by technology

However, the existing general LED bulb lamps use COB integrated light sources plus light distribution lens processing methods. Another method is to arrange the SMD light source substrates in a ring shape, so that the light sources emit light toward the surroundings. Although the light distribution obtained in this way can reach The requirement of greater than 180 degrees, but the arc of the light shape is not smooth, and the local jitter is large, which will make the illuminance may appear in a state of uneven transition between bright and dark

[0004] Due to the advantages of high light transmittance and high-grade texture of glass, there are many lamp housings made of glass in the market, but glass lamp housings are easy to break and cause injuries. The live parts such as board lines are exposed, which is easy to cause electric shock and cause safety problems.
