This application discusses components that can be used to prevent flame or hot gas transmission from the inside of a luminaire enclosure to the outside of a luminaire enclosure due to an internal explosion, thereby yielding an explosion encapsulating luminaire enclosure. Accordingly, the components and assemblies described herein can be safely integrated with systems that operate in the presence explosive gas.

The present invention relates to the technical field of vehicle illumination and, in particular, relates to a vehicle lamp optical element assembly, a vehicle lamp comprising the vehicle lamp optical element assembly, and an automobile comprising the vehicle lamp. The vehicle lamp optical element assembly comprises a primary optical element assembly and a secondary optical element assembly, wherein the primary optical element assembly comprises a primary optical element and a first support for supporting the primary optical element, and the secondary optical element assembly comprises a secondary optical element and a second support for supporting the secondary optical element, wherein the first support and the second support are connected in a matching manner so as to enable the primary optical element and the secondary optical element to be relatively fixed. The primary optical element and the secondary optical element are assembled into an integral structure, such that relative positions of the primary optical element and the secondary optical element are directly determined, and direct positioning between the primary optical element and the secondary optical element is realized. The positioning precision and the mounting reliability of the primary optical element and the secondary optical element can be ensured, such that the accuracy and functional stability of a light shape of the vehicle lamp are ensured.

Electrical lighting housings and heat sinks constructed of pitch-based carbon fiber that act as heat sinks for light emitting diode (“LED”/“LEDs”) lights. Greater heat dissipation cools the LED lights and power suppling components, which in turns increases the life span of these components, without the need for active cooling. Due to the improved physical strength of pitch-based carbon fiber over aluminum and other typical heat sink and housing materials, the wall thickness of a housing can be decreased when using pitch-based carbon fiber which can further aid in thermal transfer.

First adapter (10) and second adapter (40) are each separately securable to a respective automotive light bar (200, 201) at mutually facing lateral light bar end caps (206). The adapters (10, 40) interfit, such as first adapter (10) having one or more tenons (14; 18) received in shape-conforming recess or mortise (44) of second adapter (40). The coupling assembly formed from interfit first and second adapters (10, 40) sufficiently supports a midspan region of conjoined light bars (200, 201) to permit omission of mounting L-brackets (208) conventionally required at the mutually facing light bar ends (206), thus allowing fewer holes to be drilled in vehicle roof or bumper (212) and resulting in an aesthetically cleaner presentation of the overall lengthened light bar assembly.

A seamless lighting arrangement for a vehicle panel. The vehicle panel has an inside surface and an outside surface. The vehicle panel has a light aperture extending from the inside surface of the vehicle panel to the outside surface of the vehicle panel. Connected to the inside surface of the vehicle panel is a bracket. The seamless lighting arrangement further includes a lens with a bracket connection portion that connects to the bracket and a transmission portion positioned within the light aperture of the vehicle panel. The lens further includes a light unit fixedly connected to the lens. The light unit has a projector port for emitting light from a light source. The light transmission portion of the lens has a light input surface region formed on an inside surface of the lens and a light output surface region formed on an outside surface of the lens.

Apparatus and methods for lighting. The apparatus may include an LED light source. The light source may be disposed in housing. The apparatus may include a circuit. The circuit may be configured to cause the LED light source to emit light at: a first intensity; and a second intensity that is different from the first intensity. The apparatus may include a mechanical power state selector. A user may use the power state selector to select between LED light sources that are arranged to illuminate in different directions. The apparatus may include a CCT state selector. A user may use the CCT state selector to select a CCT for one or more LED light sources. The CCT may be produced by combining light from one or more LEDs of different CCTs.

Provided is a refrigerator. The refrigerator includes a cabinet in which a storage space is defined and a door which is configured to open and close the storage space and into which an insulating material is filled. The door includes an outer plate which is configured to define a front surface of the door and in which an opening is defined, a panel assembly configured to shield the opening so that the inside of the door is seen therethrough, a supporter frame mounted on a rear surface of the outer plate and configured to support a circumference of the opening and a circumference of the panel assembly, and a display device which is mounted on the supporter frame in which a plurality of LEDs are continuously disposed on a substrate. A transmission portion through which light irradiated from the display is transmitted is provided in the display device.

A joint assembly for luminaires is provided. The joint assembly includes a pin having at least one pin section with an upper opening, a side opening, and a bore connecting the upper opening and the side opening.
