Abstract
The present disclosure relates to an indirect lighting fixture and includes a light source assembly, a reflector structure component, a bottom structure component and an appearance structure component. The direct light from the light source assembly irradiates symmetrically on the inner surface of the reflector structure component and is reflected and diffusely reflected, and then emitted from the light outlet of the bottom structure component. The direct light of the light source assembly is designed to be invisible. This innovation transforms the hotspot direct light of the light source assembly into more soft light of the surface light source, and the high-efficiency reflector structure component allows indirect lighting fixtures to achieve high light efficiency simultaneously.
