The present disclosures provides a collar for positioning at least partially around a recessed light fitting and between the recessed light fitting and a structural body. The collar comprises a plurality of collar portions each of which are configured to surround a portion of the recessed light fitting.

A high-efficiency linear light source focused strip lamp has a strip lamp frame, a strip lamp plate provided on the strip lamp frame, a condensing lens arranged above the light emitting direction of the light-emitting chip, and a strip lamp cover connected to the strip lamp frame and located above the condensing lens; the strip lamp cover is provided with a convex lens array that visually stretches the light-emitting chip along a length direction. The high-efficiency linear light source focused strip lamp performs light distribution through the concentrating lens in the vertical length direction, and achieves high-efficiency sweeping function, and in the longitudinal direction, the light-emitting chip is performed visually stretching by the convex lens arrays on the strip lamp cover, thus achieving the effect of the line light source, solves the original glare problem without affecting the efficiency.

A portable light may comprise: a light body having an internal cavity configured to receive a rechargeable power source, having a keying feature, and having an opening through an exterior wall in a predetermined location relative to the keying feature; and a light source. A rechargeable power source has a charging connector and a keying feature in predetermined locations that when the keying feature thereof engages the keying feature of the internal cavity, the charging connector thereof is aligned with the opening through the exterior wall of the light body. Thus an external source of charging power can be connected through the opening in the exterior wall directly to the charging connector of the rechargeable power source for recharging the rechargeable power source while it is in the portable light.

A receiver speed ring configured to facilitate a safe way of mounting an associated light modifier to both a Balcar-type light source and a Bowens-type light source via a tube with outwardly protruding tabs as well as holes and slots that are punched into the tube, instead of the flared flange, which allows for a quick change between different light mounting systems (e.g., Balcar-type, Bowens-type) without obscuring or impeding a flash tube. The receiver speed ring includes a cylindrical hollow tube having a constant diameter and provided with a circumferential outer surface having a centrally registered longitudinal axis. The speed ring also includes a non-flared outer edge, a plurality of juxtaposed holes, a plurality of juxtaposed slots, and a plurality of juxtaposed outwardly protruding tabs are provided.

A light head for a medical device support system. The light head includes a housing base, an annular shape first lens, a housing cover, and a motion transfer member. The housing cover includes a cavity within which the annular shape first lens is rotatable about a rotation axis. The housing cover includes a second lens. The annular shape first lens and the second lens are in a light emitting path of the plurality of light emitting elements. The motion transfer member is configured to movably interact with a boss of the annular shape first lens to rotate the annular shape first lens about the rotation axis and within the cavity. A periphery of the annular shape first lens includes guide members configured to position the boss of the annular shape first lens to movably interact with the motion transfer member.

A luminaire bezel attachment assembly with a lens that is defined by a lens body with one or more bezel engagement keyways, and a flange around the lens body. An inner bezel is coupled to the lens and defined by one or more inner bezel keys receivable within the corresponding one of the one or more bezel engagement keyways of the lens. An outer bezel is coupled to the lens and defined by one or more outer bezel keys that are receivable within the corresponding one of the one or more bezel engagement keyways of the lens. The outer bezel keys overlap the corresponding one of the one or more inner bezel keys.

Apparatus providing beamforming and environmental protection for LED light sources. A lens apparatus is provided to protect an LED mounted on a substrate. The lens apparatus includes an alignment feature configured to align the LED to a selected position and a focusing region configured to form a selected beam pattern from light emitted from the LED when located at the selected position. The lens apparatus also includes a compression surface configured to compress the substrate to a heat sink to facilitate heat dissipation from the LED and a fastening feature configured to fasten the lens apparatus to the heat sink to provide an environmentally protective seal, so that when the lens apparatus is fastened to the heat sink the alignment feature aligns the LED to the selected position, the compression surface compresses the substrate to the heat sink, and the protective seal protects the LED from environmental conditions.

An LED module is disclosed, which includes one or more LED light sources and one or more lenses. Each lens includes a lens body. The lens body includes an inner cavity having an incident surface, an emergent surface, and a reflective surface extending between the incident surface and the emergent surface for providing total internal reflection. One LED light source is situated in the inner cavity. Light emitted from the LED light source is transmitted by the incident surface. At least portion of transmitted light by the incident surface is reflected by the reflective surface to the emergent surface so as to provide a narrow light beam angle perpendicular to a length direction of the LED module. The emergent surface has a plurality of micro structures for enlarging a light viewing angle in the length direction. A sign box using one or more LED modules is also disclosed.

A lens for a light-emitting diode (LED) provides an even light pattern over a desired throw of light. An indentation on the top of the lens and a lens collector on the bottom are configured for a desired spread angle of light refracted an LED positioned on a circuit board below the light collector of the lens. One or more lenses may be formed in a lens unit for assembly with a circuit boards and molding into an LED module. The module may be used in sign cabinet and other lighting applications where LEDs are used as light sources.
