The shortcomings are summarized as follows:

一、现有技术中的LED灯泡之颈部没有对电路板作很好地保护,使得LED灯泡的导通不稳定,缺乏可靠性,甚至会导致短路、漏电等现象的出现,存在着较大的安全隐患。1. The neck of the LED bulb in the prior art does not protect the circuit board well, which makes the conduction of the LED bulb unstable, lacks reliability, and even causes short circuit, leakage, etc., and there is a large Security risks.

二、现有技术中的电路板大多采用焊接的方式与灯盘电连接,该种连接方式不便于零部件的组装、维护和更换,更不利于提高生产效率和经济效益,所以不利于市场的推广。2. Most of the circuit boards in the prior art are electrically connected to the lamp panel by means of soldering.
