Problems solved by technology

However, in long-term use, it is found that because the lampshade of the bulb is usually made of plastic material, it is easy to deform after being heated, so that a small gap will be formed at the junction of the lampshade and the radiator, so that dust will enter the lampshade through the above-mentioned fine gap. So that it will affect the lighting effect of LED bulbs

Abstract

The invention discloses an LED lamp bulb high in sealing performance. The LED lamp bulb high in sealing performance comprises a lamp holder (2), a radiator (4) and a lampshade (6). The lamp holder (2) is connected with the top of the radiator (4). The lampshade (6) is connected with the bottom of the radiator (4). A round PCB (8) is arranged on the bottom wall of the radiator (4). A plurality of LED wafers (9) are arranged on the PCB at equal intervals. The LED lamp bulb is characterized in that the lampshade (6) and the radiator (4) are in threaded fit connection, and a circle of elastic rubber ring (10) is arranged on the joint of the lampshade (6) and the radiator (4). The LED lamp bulb has good sealing performance.

Description

technical field [0001] The invention relates to a light bulb, in particular to an LED light bulb with better sealing performance. Background technique [0002] At present, as a home lighting fixture used to replace tungsten lamps and fluorescent lamps, LED lamps have the advantages of low energy consumption, high light efficiency, no mercury, no radiation pollution, and renewable materials. Today, it is becoming more and more popular with consumers. However, in long-term use, it is found that because the lampshade of the bulb is usually made of plastic material, it is easy to deform after being heated, so that a small gap will be formed at the junction of the lampshade and the radiator, so that dust will enter the lampshade through the above-mentioned fine gap. So that it will affect the lighting effect of LED bulbs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an LED light bulb with better sealing performan...
