US Patent:

20040184272, Sep 23, 2004

Filed:

Mar 22, 2004

Appl. No.:

10/805920

Inventors:

Steven Wright - La Jolla CA, US
Patrick Mullins - San Diego CA, US

International Classification:

H01L023/36
F21V029/00

US Classification:

362/373000, 362/249000, 362/800000, 257/706000

Abstract:

A disclosed substrate includes an electrically insulating circuit board, a pair of electrical lead pads adapted for mounting a light-emitting diode (LED) on a first surface, and a heat dissipating structure on the first surface. The heat dissipating structure includes an LED thermal pad adapted to abut the LED when mounted on the electrical lead pads, and a heat dissipation region extending from, and thermally coupled to, the LED thermal pad. The substrate also includes a thermally conductive plating on a second surface of the substrate opposite the heat dissipation region. A described lighting assembly includes the substrate, multiple LEDs connected to the electrical lead pads of the substrate, and multiple traces of the substrate connect the LEDs in a series circuit electrically isolated from the heat dissipating structures.

International Classification:

H01L027/15

Abstract:

A photosensor control unit for use in a lighting module has a plurality of LEDs, a light sensor, and a switch adapted to operably control the plurality of LEDs responsive to the light sensor. The plurality of LEDs are adapted to be mounted in the lighting module, and are configured to produce light having wavelengths within a first range of wavelengths. The light sensor is adapted to be mounted in the lighting module adjacent the plurality of LEDs, and is responsive to light having wavelengths within a second range of wavelengths. The second range of wavelengths is exclusive of the first range of wavelengths. The switch is adapted to operably control the plurality of LEDs responsive to the light sensor such that the plurality of LEDs emit light having wavelengths within the first range of wavelengths responsive to the presence or absence of light within the second range of wavelengths.
