At present, the most popular ceiling lamp on the market is LED ceiling lamp, which is often used in various places such as homes, offices, and cultural relics.

[0003] RGBW light source is a type of LED light source. Specifically, RGBW refers to an LED light source that contains four colors: red (R), green (G), blue (B) and white (W).

[0004] The light sources in ceiling lamps currently on the market will age and become damaged due to use, so the light sources often need to be replaced. When replacing, the operator needs to use tools to unscrew the bolts of the lampshade and then replace the light source. Before replacing the light source, the operator needs to place the lampshade, either on a ladder or by climbing back and forth to place the lampshade on the ground. When the lampshade is placed on the ladder, the operator may touch the lampshade when replacing the light source, and there is a risk of the lampshade falling. When the operator replaces the light source, it is generally fixed with screws. However, it is inconvenient for the operator to operate on the ladder, and there is a possibility of the screws falling. All of these have caused the operator to take a longer time to replace the light source, and the longer the replacement time, the greater the chance of an accidental fall.
