Abstract: A lighting apparatus and a method for manufacturing the same. A lighting apparatus is provided, including: a transparent portion including a first surface, a second surface and an edge connected to the first surface and the second surface, the edge including an inner surface with a preset shape; and a light source fixed on the transparent portion so that the inner surface receives light emitted by the light source and reflects it to at least one of the first surface and the second surface. The preset shape has a certain relationship with distribution of light emitted to the first surface and the second surface. The method for manufacturing just designs the preset shape during designing stage so as to satisfy requirements for distribution of the light emitted to the first surface and the second surface.

Abstract: This invention provides a ventilation kit adapted to be coupled to a recessed light fixture, and comprises two supporting members. The first is adapted to be coupled with at least one edge of the recessed light fixture, while the second is adapted to be coupled with the grid system of the ceiling. There is also through-hole for air circulation. Mounting the ventilation kit onto an existing recessed light fixture enables the existing recessed light fixtures to have either an air supply or air return ventilation feature. This invention also discloses a recessed light fixture assembly with either an air supply or air return ventilation feature.

Abstract: The present invention provides a recessed light fixture comprising a housing and a bottom plate, wherein the housing is composed of a first side wall and a second side wall opposite to each other, with both the first side wall and the second side wall are respectively provided with a first latching portion and a second latching portion, and the bottom plate is a light diffuser plate or a ventilation plate.
