The present disclosure provides a lamp. The lamp includes a housing with an inner cavity and a lamp base. At least a portion of the lamp base is disposed in the inner cavity. The housing includes a plurality of supporting frames. The supporting frames are movably connected end by end to enclose the inner cavity. Two adjacent supporting frames are detachably connected with each other.

A lighting fixture and method of providing lighting is provided herein that utilizes both direct and indirect light sources. The direct and indirect light sources can be provided in arrays of light emitting diodes (LEDs) oriented along desired axes. In some versions, the light fixtures described herein include a direct lighting array having one or more LEDs oriented to project light downwardly and an indirect lighting array having a plurality of LEDs oriented to project light in a transverse direction. Further, the light fixtures can include an indirect lighting member configured to be illuminated by the plurality of LEDs of the indirect lighting array. Additionally, or alternatively, the light fixtures described herein can include one or more controllers that are configured to independently operate the direct and indirect lighting arrays. Moreover, the indirect lighting array can be configured to emit light in a plurality of colors to visually convey information.

The present teaching relates to an illumination module for emitting light directed in parallel in a main emission direction, having a reflector with a focus lying on the front side thereof. At least one LED light source is arranged substantially at the focus of the reflector for radiating light into the reflector. A heatsink is arranged on the rear side of the reflector. The LED light source is oriented counter to the main emission direction. The reflector is configured to direct the light radiated into the reflector by the at least one LED light source in parallel and emit the light in the direction of the main emission direction. The at least one LED light source is held by means of at least one connecting web extending from the heatsink to the LED light source.

A vehicular interior lighting device includes a main body portion fixed to an inside surface of a roof, a light source accommodated in the main body portion, a light shielding cover portion constituting a housing with the main body portion and covering the light source from below, and a light guide member having a protruding portion protruding along the inside surface from a gap between the main body portion and the cover portion. The light guide member has a diffusion portion formed on a surface of the protruding portion facing downward and diffusing light, a first light guide portion guiding light emitted from the light source to the protruding portion, and a reflecting portion reflecting light guided by the first light guide portion toward the diffusion portion.

Illumination devices with adjustable optical elements configured to provide a variable illumination pattern of an area are described. The adjustable optical elements of the illumination devices can be traversed relative to a surface (e.g., a ceiling of a room) to vary the light distribution and/or intensity to the surface.

A retrofit lighting fixture comprises a lighting fixture component and a retrofit component. The lighting fixture component comprises a primary light component, a primary trim and a primary power component. The retrofit component comprises a secondary light component, a lighting frame and a secondary power component.

A luminaire includes multiple light-emitting elements (LEEs); a base supporting the LEEs; and a first wall and a second wall each extending along a first direction from a respective first end facing the LEEs to a respective second end. The first and second walls have light-reflective surfaces facing each other. In one or more cross-sectional planes parallel to the first direction, the light-reflective surfaces of the first and second walls have first portions that curve in opposite directions, second portions that are parallel, and third portions that curve in like directions. The first portions are arranged facing the LEEs to provide an input aperture that receives light from the LEEs. The third portions are arranged to provide an exit aperture that outputs output light into an ambient environment. The first and second walls are configured to propagate light from the input aperture to the exit aperture.
