Abstract

An LED bulb easy to maintain comprises a lamp holder (2), a radiator (4) and a lamp shade (6); the lamp holder (2) is connected with the top of the radiator (4); the lamp shade (6) is connected with the bottom of the radiator (4); a PCB (8) is disposed below the radiator (4); and the PCB (8) is provided with a plurality of LED wafers, with uniform intervals, for emitting light. The PCB is prevented from being fixed by screws, so that maintenance is relatively convenient.

Description

technical field [0001] The invention relates to a light bulb, in particular to an easily maintained LED light bulb. 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. As we all know, the disassembly and assembly of the existing LED light bulbs is troublesome, and the specific PCB board must be fixed on the heat sink with screws. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an easily maintained LED light bulb. [0004] In order to solve the above technical problems, the present invention provides an LED light bulb that is easy to maintain, including a lamp base, a radiator and a lampshade, the lamp holder is connected to the top of the radia...
