An apparatus and method for covering the optical system of a moving head light fixture with a filter or diffuser when the lighting fixture is turned off is provided. The filter or diffuser is positioned in the optical path between a lighting element and a lens. A retraction device is energized to retract the filter or diffuser from the optical path during normal operation. Upon removal of power to the fixture, the filter mechanism automatically returns the filter or diffuser to its position in the optical path. In this way, the optical system of the fixture can be protected from damage caused by impinging strong light and/or sunlight when the fixture is not in use.

The present disclosure provides a backlight module and a display device. The backlight module includes: module substrate provided with a power supply line and a mounting region integrally; and a light emitting source assembly detachably disposed in the mounting region and electrically connected to the power supply line.

An outdoor area LED lighting system including: a housing containing a large array of LEDs mounted to an aluminum direct thermal path printed circuit board and a single lens. The large array of LEDs are capable of producing light rays directed through the single lens to produce a beam of light to illuminate the outdoor area. The single lens is preferably a Fresnel lens. The housing is preferably capable of being sealed in a weather-tight manner. A second housing may at least partially surround the first housing such that at least one air passage is provided between the first housing and the second housing. A heat sink including a heat block in thermal communication with a plurality of heat tubes and fin assemblies may be in partial thermal contact with the LED module and in fluid communication with the at least one air passage. At least one fan may be provided in or in fluid communication with said at least one air passage to cool the heat sink. A digital interface may connect the LED module to a host computer to monitor and track information and trending for statistical process control.

Provided is a fire-resistance housing for a light fixture comprising: an outer can made from a metal; an inner can made from a metal; and a non-metal, in-organic, non-combustible material in between the outer can and the inner can; wherein a source of light is placed inside of the inner can to provide illumination.

An LED lens assembly that includes a secondary lens and a gasket molded to the secondary lens. At least one of the secondary lens and the gasket is made of a material that is curable using low temperature electromagnetic radiation.

A method and system for an area illumination device includes a support channel includes a power supply end, a first coupling end, and a first elongate body extending therebetween. A surface mounting assembly is fixedly coupled to the support channel and is configured to removably engage a first support surface of a plurality of support surfaces. A light arm includes a second coupling end, a fixture end, and a second elongate body extending therebetween. A main joint assembly is operably coupled to the first coupling end and the second coupling end and includes a plurality of degrees of freedom of motion. A light fixture includes a plurality of individual light sources coupled to the fixture end through a fixture joint assembly having at least two degrees of freedom of movement.

A concealer plate for a lighting fixture includes a first concealer plate surface, a second concealer plate surface, and two or more magnets. The magnets are recessed in the first concealer plate surface such that the magnets are inset from the first concealer plate surface by approximately a predetermined depth. Each one of the magnets is configured to magnetically engage one of a number of fasteners protruding from a mounting portion of a trim of the lighting fixture by a distance that is approximately equal to the predetermined depth. Accordingly, the second concealer plate surface hides the fasteners from view. The concealer plate hides one or more fasteners exposed on the lighting fixture while avoiding any interference in the operation of the lighting fixture and is easily installed onto currently existing lighting fixtures.

A light fixture includes a housing and a light emitting element. The housing includes a lower edge and is configured to be recessed within a surface. The light emitting element is supported in the housing, and the light emitting element includes a planar surface spaced apart from the lower edge of the housing.
