A discontinuity-containing, light-diffusing substrate is placed within an LED light source. In one embodiment, the substrate is placed between an LED light source and a light guide. The light diffusing substrate may include a plurality of air bubbles, grooves or both, effective to mix the colored light and yield a white light exiting the light guide. Methods of constructing optical devices and light sources having a bubble-containing substrate are also disclosed.

System and method for light source with discontinuity-containing diffusant

A light source and a method for operating the same are disclosed. The light source includes a light emitter and a controller. The light emitter generates light in response to a control signal coupled thereto. The light emitter is characterized by an age related to the amount of light that has been cumulatively generated by the light emitter, the generated light for a given control signal changing with the age. The controller measures the age of the light emitter and generates the control signal based on the desired light intensity and the measured age of the light emitter. In one embodiment, the controller stores an age value for the light emitter, and the controller determines the control signal in response to an input signal specifying a desired light intensity from the light emitter, the controller updating the age value each time the control signal is determined.

Color management system

A light source that has improved light mixing. The light source uses a nanolens layer in conjunction with an LED light source to enhance the mixing of the colored light emitting from the LED light source.

LED light source with light-directing structures

A lighting system is described. One embodiment of the lighting system includes a light guide, a first lighting device, and a second lighting device. The light guide receives light along a transmission interface. The first lighting device has a first plurality of lighting elements coupled to a first substrate between a first pair of reflector walls. The first substrate and the first pair of reflector walls define a first exposed side of the first lighting device. The second lighting device has a second plurality of lighting elements coupled to a second substrate between a second pair of reflector walls. The second substrate and the second pair of reflector walls define a second exposed side of the second lighting device configured to match the first exposed side of the first lighting device. Using lighting devices without sidewalls illuminates a diffusion panel so that there are no dark spots.

Light emitting diode

A light source and a method for making the same are disclosed. The light source includes a lead frame, an integrated circuit chip and a body. The lead frame has first and second sections. The first section includes a lateral portion, a chip mounting area and a first extension. The integrated circuit chip is bonded to the first section in the chip mounting area and is in thermal contact with the chip mounting area. The body has top, bottom, and side surfaces. The first extension is bent to provide a heat path from the chip mounting area to the side surface, a surface of the first extension that is not in contact with the side surface forming a first planar bonding surface. The heat path has less thermal resistance than a heat path through the lateral portion.

Side-emitting LED package with improved heat dissipation

An electronic flash, imaging device and method for producing flashes of light uses a diffractive optical element to produce a flash of light having a rectangular radiation pattern. The diffractive optical element is configured to diffract light emitted from a light source such that the radiation pattern of the light emitted from the diffractive optical element is rectangular to produce the rectangular flash of light.

In one embodiment, light emitted by a plurality of solid-state light emitters is mixed by mounting the plurality of solid-state light emitters on a transparent to translucent substrate so that they primarily emit light away from the substrate. The light emitters are then covered with a transparent to translucent encapsulant; and the encapsulant is coated with a reflective material that reflects light emitted by the light emitters toward the substrate. Related apparatus is also disclosed.

In one embodiment, a light emitting panel includes a base panel and a plurality of light emitting elements mounted to the base panel. Each of the light emitting elements produces an illumination pattern having a region of substantially uniform intensity that extends over a radiation angle of at least about 60&#xb0;. One or more light conditioners are positioned adjacent the base panel to receive and condition light produced by the light emitting elements.
