Description

Technical Field

[0002] The LED candle lamp bulb belongs to a kind of LED bulb. The LED bulbs in the current market usually include a lamp head, on which a lampshade is assembled. A light source is arranged inside the lampshade, and the lower end of the lampshade is connected to a lamp socket. The driving power supply is installed inside the lamp head, and the light source is a cylindrical structure formed by enclosing two or more sub-light sources. For such an LED bulb with this structure, although the lampshade is integrally detachable, however, since the lamp socket is directly fixedly connected to the lamp head by welding, the light source is also directly fixed on the lamp socket by welding, and the driving power supply is even directly fixed on the light source by welding. When the light source or the driving power supply of the lamp is damaged for various reasons, the light source or the driving power supply cannot be directly replaced, and only the whole bulb can be replaced, which greatly increases the maintenance cost.
