摘要： A lighting device capable of generating warm or neutral white light using blue light-emitting diodes (“LEDs”), red LEDs, and/or luminescent material that responds to blue LED emission is disclosed. The lighting device includes multiple first solid-state light-emitting structures (“SLSs”), second SLSs, and balancing resistor element. The first SLS such as a string of blue LED dies connected in series is able to convert electrical energy to blue optical light, which is partially turned into longer wavelength emission by the luminescent material. The second SLS such as a red LED die is configured to convert electrical energy to red optical light, wherein the second SLSs are connected in series. While the first SLSs and second SLSs are coupled in parallel, the balancing resistor element provides load balance for current redistribution between the first and second SLSs in response to fluctuation of operating temperature.

摘要： Carbon nanotube (CNT) arrays can be used as a thermal interface materials (TIMs). Using a phase sensitive transient thermo-reflectance (PSTTR) technique, the thermal conductance of the two interfaces on either side of the CNT arrays can be measured. The physically bonded interface has a conductance ˜105 W/m2-K and is the dominant resistance. Also by bonding CNTs to target surfaces using indium, it can be demonstrated that the conductance can be increased to ˜106 W/m2-K making it attractive as a thermal interface material (TIM).

摘要： Solid state lamp or bulb structures are disclosed that can provide an essentially omnidirectional emission pattern from directional emitting light sources, such as forward emitting light sources. The present invention is also directed to lamp structures using active elements to assist in thermal management of the lamp structures and in some embodiments to reduce the convective thermal resistance around certain of the lamp elements to increase the natural heat convection away from the lamp. Some embodiments include integral fans or other active elements that move air over the surfaces of a heat sink, while other embodiments comprise internal fans or other active elements that can draw air internal to the lamp. The fan's movement of the air over these surfaces can agitate otherwise stagnant air to decrease the convective thermal resistance and increasing the ability of the lamp to dissipate heat generated during operation.

摘要： A wide beam angle (diffuse) luminaire with an efficient multi-source radiative emitter array. Embodiments of the luminaire utilize one or more LEDs disposed around a perimeter of a protective casing. The LEDs are angled to emit into an internal cavity defined by the inner surface of the casing. The placement of the LEDs around the perimeter of the device reduces self-blocking and facilitates heat transfer from the LEDs through the casing or another heat sink and into the ambient. Light impinges on the inner surface and is redirected as useful emission. A diffuse reflective coating may be deposited on the inner surface to mix the light before it is emitted.
