Appl. No.:

13/088710

International Classification:

F21V 29/00

US Classification:

362294, 362547, 362549, 257712

Abstract:

A mounting collar on a light fixture provides a compressive force between the illumination module and a light fixture. For example, a mounting collar that is fixed to the light fixture may engage with an illumination module to deform elastic mounting members on the illumination module to generate the compressive force. The mounting collar may include tapered features on first and second members that are moveable with respect to each other and that when engaged generate the compressive force. The mounting collar may include elastic mounting members on first and second members that move with respect to each other, wherein the movement deforms the elastic mounting members to generate the compressive force. The mounting collar may include an elastic member, wherein movement movement of the mounting collar relative to a light fixture deforms the elastic member to generate the compressive force.

International Classification:

F21V 7/00

US Classification:

362346, 36224902, 362297, 362800

Abstract:

Collection optics are used with one or more light emitting diodes to produce, e. g. , collimated light. The collection optics are produced in multiple pieces including a small reflective ring that surrounds the one or more light emitting diodes. The reflective ring may be positioned relative to the LEDs, using a mesa upon which the LEDs are mounted, as a lateral positioning guide. A separate upper reflector uses the reflective ring as a lateral positioning guide during assembly. The reflective ring and the upper reflector include reflective sidewalls that are approximately continuous when the reflective ring and upper reflector are assembled.

Abstract:

An electrical interface module (EIM) is provided between an LED illumination device and a light fixture. The EIM includes an arrangement of contacts that are adapted to be coupled to an LED illumination device and a second arrangement of contacts that are adapted to be coupled to the light fixture and may include a power converter. Additionally, an LED selection module may be included to selectively turn on or off LEDs. A communication port may be included to transmit information associated with the LED illumination device, such as identification, indication of lifetime, flux, etc. The lifetime of the LED illumination device may be measured and communicated, e. g. , by an RF signal, IR signal, wired signal or by controlling the light output of the LED illumination device. An optic that is replaceably mounted to the LED illumination device may include, e. g. , a flux sensor that is connected to the electrical interface.

International Classification:

H01L 33/00

US Classification:

257 98, 257E33061, 257E33068

Abstract:

Very thin flash modules for cameras are described that do not appear as a point source of light to the illuminated subject. Therefore, the flash is less objectionable to the subject. In one embodiment, the light emitting surface area is about 5 mm×10 mm. Low profile, side-emitting LEDs optically coupled to solid light guides enable the flash module to be thinner than 2 mm. The flash module may also be continuously energized for video recording. The module is particularly useful for cell phone cameras and other thin cameras.

International Classification:

H01L 33/00
H01L 21/00

US Classification:

257 98, 438 27, 257E33001

Abstract:

Individual side-emitting LEDs are separately positioned in a waveguide, or mounted together on a flexible mount then positioned together in a waveguide. As a result, the gap between each LED and the waveguide can be small, which may improve coupling of light from the LED into the waveguide. Since the LEDs are separately connected to the waveguide, or mounted on a flexible mount, stress to individual LEDs resulting from changes in the shape of the waveguide is reduced.
