A lighting apparatus includes a light source, a light passing cover, a back cover and a rim frame. The light source is used for emitting a light. The light passing cover has a first ladder edge. The rim frame has an inner frame and a light source holder. The back cover, the surface rim and the light passing cover define a concealed space. The light source is disposed in the light source holder in the concealed space. The inner frame defines a light opening for the light to escape from the lighting apparatus. The inner frame has a second ladder edge surrounding the light opening. The first ladder edge and the second ladder edge are pressed by the back cover to press to each other. Multiple ladder protrusion surfaces between the first ladder edge and the second ladder edge prevent water to enter the concealed space.

The first light emitting components, the second light emitting components and the third light emitting components are located in the first subpixel areas, the second subpixel areas and the third subpixel areas respectively. The first light emitting components in two adjacent first subpixel areas are electrically connected in series. The size of each of the first light emitting components is larger than the size of each of the second light emitting components and the third light emitting components.

A optically transmissive component is configured within a light fixture to provide benefits in brightness uniformity and visual appearance with the use of a light scattering extension portion that provides light scattering of light emitted from near an input edge of a light guide or other edgelit optical element. The sequential propagation of light through both the extension portion and main portion of the optically transmissive component significantly reduces the higher brightness and uneven “hotspotting” type visual defects typically produced near the input edge of an edgelit optical system. With appearance constraints removed or reduced, edgelit light fixtures with higher output, higher efficacy, and/or simplified edgelit optical components are enabled. Embodiments include the use of the extension portion of the optically transmissive component extension to mechanically position and retain an edgelit optical element within a light fixture.
