  • Patent number: 11927338
    Abstract: A lighting apparatus includes a main housing, a light module, a ventilating fan and a fixing frame. The main housing has a fan bracket and a light bracket. The light module is disposed to the light bracket for emitting a light outwardly to an illuminated space. The ventilating fan is attached to the fan bracket. The ventilating fan has an air passage exposed to the illuminated area for air to flow passing the air passage driven by the ventilating fan. The fixing frame holds the main housing and is used for fixing to one of multiple types of installation platforms. The main housing is detachable from the fixing frame. The fixing frame has two telescopic levers arranged in parallel for changing a spanning diameter to fit different installation platforms. The main housing is attached on the fixing bracket.

  • Patent number: 11892673
    Abstract: A dimming assembly includes a first prism having a first surface and a second surface opposite to each other, and a second prism disposed on a side where the second surface of the first prism is located. The first surface includes first dimming portions, each of which includes two first side surfaces. Edges of the two first side surfaces away from the second surface intersect at a first intersection line. A surface of the second prism proximate to the second surface includes second dimming portions, each of which includes two second side surfaces. Edges of the two second side surfaces proximate to the second surface intersect at a second intersection line. A distance between orthographic projections of two adjacent first intersection lines on the second surface is less than a distance between orthographic projections of two adjacent second intersection lines on the second surface.
