It also refers to an external rear view device with such a light unit.

A self-expanding light shaping device for being separably mounted on a fastening arrangement of a lighting device is provided. The light shaping device features sidewalls of flexible material, which after the mounting on the lighting device surround a light shaping and light emitting region formed between an inlet opening and an outlet opening, tensioning elements designed for stabilizing the sidewalls and a fastening mechanism for separably mounting the light shaping device on the fastening arrangement of the lighting device, wherein the outlet opening is realized in the form of a round outlet opening, which is at least sectionally enclosed by a frontal tensioning element that expands the flexible material of the sidewalls.

Disclosed is a downlight (100) comprising a mounting frame (50) to be mounted in the area of a ceiling mounting hole, and a light fixture (10) that is to be fastened to the mounting frame (50) and includes a luminaire head (30). The light fixture (10) is formed by a substantially C-shaped element having a main surface (11) and two angled wings (20) on two opposite sides of the main surface (11); the wings (20) of the light fixture (10) are designed in a flexible manner and in such a way as to interlock with the mounting frame (50).

A lighting device assembly includes a light source attached to a heat sink member, a first optic device and a mounting housing configured to be secured in or to a ceiling, wall or other object, and to hold the heat sink member. A second optic device including a second optic member is configured to receive light emitted in a first direction from the light emitting surface of the first optic device and to emit light in a second direction that is transverse to the first direction. A connection mechanism selectively connects the second optic device to the mounting housing, for selective disconnection from the mounting housing.

The disclosed invention is embodied in an improved LED-based lighting fixture for projecting a beam of light having a substantially uniform intensity, rotationally, and a selectable, substantially uniform chromaticity. The lighting fixture includes (1) a concave reflector having circumferential facets, a focal region, an aperture, and a central opening; and (2) a light source assembly including two or more groups of LEDs mounted at the forward end of an elongated, thermally conductive support. The light source assembly is mounted relative to the reflector with the elongated support's longitudinal axis aligned with the reflector's longitudinal axis and with the groups of LEDs located at or near the reflector's focal region. Each of the two or more groups of LEDs includes a plurality of LEDs arranged in a specific pattern such that they cooperate with the faceted concave reflector to project a beam of light having a selectable, substantially uniform chromaticity.

A luminaire includes a housing, a light source, and a lens. The lens has a first side and a second side and at least one of the first side and the second side has optical features. The lens can be positioned in the luminaire in a first position with the first side facing upward and in a second position with the second side facing upward. The two options for positioning the lens within the luminaire provide two different distributions for light exiting the luminaire.

A lighting apparatus for use as a surgical headlamp is disclosed. A light emitting diode is positioned in a recess within a frustoconical, thermally-conductive heat sink that has a several circumferential ridges to provide a desired surface area for heat transfer. The diode and the heat sink are provided in a housing that also includes a fan for drawing ambient air into the housing to contact the heat sink and exhausting heated air. A lens is snap-fit into a slide that frictionally engages the interior of the housing, allowing a user to adjust the spacing between the light emitting diode and the lens as desired. Personal cooling apparatuses usable with the lighting apparatus are also described. Auxiliary undergown switches are also described as are personal cooling apparatuses.

A cable clamp for holding a cable, preferably for an LED driver, including a clamp cover and a clamp gear which can be joined together, thereby defining an inner space for accommodating a portion of the cable, and a bracket placed inside the inner space and configured to apply a clamping force on the cable, wherein the bracket is adjustable in a direction perpendicular to the axial direction of the cable such that the bracket can take different positions in the joined state.

The present disclosure provides a backlight module and a display device. The backlight module includes a back plate comprising a base plate and at least one side wall defining an accommodation space, a frame, at least a portion of which is accommodated in the space. The frame comprises at least one side surface arranged opposite to the side wall. Clamping hooks are arranged on the side surface, and matching parts are arranged on the side wall and correspond with the clamping hooks. The clamping hook comprises a first portion connected to the side surface and a second portion formed by bending and extending the first portion. The matching part comprises a hook hole portion and a retainer portion arranged around the hook hole portion. The first portion may be inserted into the hook hole portion, and the second portion is clamped by and fixed with the retainer portion.
