Since the LED light source and the lamp cap are mounted on both ends of the heat sink, the heat sink usually has a certain length, otherwise the heat dissipation requirement of the LED operation will not be achieved. Limited by the LED running heat requirements, the current LED bulb body is usually longer than the ordinary bulb, and can not be the same as the existing ordinary bulb. The LED bulb with a long lamp body is not only limited in scope of use. When installed on an existing lamp, the light bulb exposed outside the lampshade illuminates the human eye, causing discomfort and being screwed on the lamp holder. The LED bulb driver is exposed and appears to be uncoordinated and unattractive. Summary of the invention
