Abstract: A light-emitting device having an inner reflective body and an outer non-reflective body is disclosed. The inner reflective body defines a reflector configured to reflect light. In one embodiment, the outer non-reflective body encloses the inner reflective body to minimize reflectivity of the light-emitting device. When assembled into an infotainment display system, the outer non-reflective body may be configured to reduce reflection of ambient light and hence, increase contrast ratio of the display. Reliability performance of the light-emitting device may be improved by using interlocking aperture at the lead frame, interlock structure and interlock geometries defined by the inner reflective body and the outer non-reflective body.

Abstract: A package for a light source is disclosed. In particular, a Plastic Leaded Chip Carrier (PLCC) is described which provides enhanced heat dissipating properties. Moreover, the PLCC is described as comprising a single-gage leadframe, which provides for enhanced design flexibility and reduced manufacturing costs. Methods of manufacturing light source packages are also disclosed.

Abstract: A lead frame package with multiple bends suitable for a light-emitting device, as well as a non-optical device is disclosed. A light-emitting device incorporating the lead frame package with multiple bends may comprise a light source die, a body and a plurality of leads. A non-optical device incorporating the lead frame package may comprise a die, a body and a plurality of leads. Each of the leads has at least first, second, and third bends defining each of the leads into at least first, second, third and fourth sections. At least the second section, the third section and the second bends of each lead are encapsulated by an encapsulating material forming the body.

Abstract: A light source and method for making the same are disclosed. The light source includes a substrate, a die, and a cup. The substrate has a plurality of electrical traces thereon and the die includes an LED that is connected to two of the traces. The cup overlies the substrate and is filled with an encapsulant material. The die is located within the cup and is encapsulated by the substrate and the encapsulant material. The cup and encapsulant material have substantially the same coefficient of thermal expansion. The cup can include reflective sidewalls positioned to reflect light leaving the die. The cup, encapsulant and substrate can be constructed from the same material.

Abstract: 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.

Abstract: 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.

Abstract: Illumination apparatus includes a support structure, at least one light emitting element, and a heat sink thermally coupled to the light emitting element. The light emitting element and heat sink are moveable in relation to the support structure. An actuator system moves the at least one light emitting element and the heat sink with respect to the support structure.

Abstract: A light source is disclosed. The light source has a light-emitting chip that includes an LED that generates light in an active region thereof. The LED emits a light signal in a forward direction, and infrared radiation generated in the active region is emitted in a side direction in the form of a first infrared signal. The first light signal is determined by a first drive signal coupled to the LED. The light source also includes an infrared detector positioned to collect a portion of the infrared signal. The infrared detector generates a heat signal indicative of the amount of infrared radiation detected. A controller generates the drive signal so as to maintain the heat signal at a first target value. In light sources having LEDs that emit in different spectral ranges, the infrared detectors can all detect heat in the same spectral range.

Abstract: In one embodiment, apparatus is provided with at least one solid-state light emitter, at least one fiber optic light guide, at least one photosensor, and a control system. Each of the at least one fiber optic light guide has a first end that is independently positionable with respect to the solid-state light emitter(s) to receive the light emitted by the solid-state light emitter(s). Each photosensor is positioned to receive light emitted from a second end of one of the light guides. The control system is operably associated with the solid-state light emitter(s) and the photosensor(s) to regulate the light output of the light emitter(s) in accordance with measurements received from the photosensor(s).
