Abstract: A lamp base includes a lamp body, a ring frame and a circumferential projection component. The lamp body includes an illuminating component, a ring frame and a circumferential projection component. The ring frame surrounds the lamp body. Such that the lamp body is seated within the ring frame. The ring frame also rotates relative to the lamp body along a rotational axis of the lamp base. The circumferential projection component has an inner circular through hole to allow the lamp body to pass through. The circumferential projection component detachably and rotatably engages with the ring frame. The lamp body rotates relative to at least one of the ring frame and the circumferential projection component along the rotational axis, so as to adjust an illumination angle of the illuminating component.

Abstract: A LED downlight apparatus includes a light source plate, a heat sink, a reflective cup and a driver container. The reflective cup reflects light of the light source plate and the heat sink is arranged between the driver container and the light source plate.
