[0002] The projection lamp toy can transmit light and shadow to the wall or ceiling after the lights in the room are turned off, creating a dreamlike and wonderful space atmosphere. It can project various different scenes and is deeply loved by children. The Chinese utility model patent with the authorization announcement number CN221281390U discloses a high-definition projection device, which includes a base and a lamp board fixed to the base. The lamp board includes a substrate and an LED chip installed on the substrate. The LED chip is electrically connected to the substrate. The projection film cover is arranged above the lamp board, and the light emitted by the LED chip passes through the projection film. Although the structural design of the high-definition projection device can effectively realize the projection of clear patterns on the ceiling or wall, its lamp board is directly externally placed above the rotating seat, and the electrical components of the lamp board are exposed to the outside, which easily causes the electrical components of the lamp board to directly contact the human body, thereby causing safety accidents. To this end, we propose a new type of projection lamp base and projection lamp. Utility Model Content
