摘要： Fabrication of a light emitting device includes etching of a substrate of the light emitting device. The etch may be an aqueous etch sufficient to increase an amount of light extracted through the substrate. The etch may be a direct aqueous etch of a silicon carbide substrate. The etch may remove damage from the substrate that results from other processing of the substrate, such as damage from sawing the substrate. The etch may remove an amorphous region of silicon carbide in the substrate.

摘要： A light-emitting device includes a substrate that is at least partially transparent to optical radiation and has a first index of refraction. A diode region is disposed on a first surface of the substrate and is configured to emit light responsive to a voltage applied thereto. An encapsulation layer is disposed on a second surface of the substrate and has a second index of refraction. An antireflective layer is disposed between a second surface of the substrate and the encapsulation layer. The antireflective layer has a graded index of refraction having values in a range between about the first index of refraction at a first surface of the antireflective layer and about the second index of refraction at a second surface of the antireflective layer. The encapsulation layer may also be omitted and the antireflective layer may separate the substrate, which has a first index of refraction, from air, which has a second index of refraction. Non “flip-chip” embodiments are also disclosed.

摘要： Light emitting device die having a mesa configuration on a substrate and an electrode on the mesa are attached to a submount in a flip-chip configuration by forming predefined pattern of conductive die attach material on at least one of the electrode and the submount and mounting the light emitting device die to the submount. The predefined pattern of conductive die attach material is selected so as to prevent the conductive die attach material from contacting regions of having opposite conductivity types when the light emitting device die is mounted to the submount. The predefined pattern of conductive die attach material may provide a volume of die attach material that is less than a volume defined by an area of the electrode and a distance between the electrode and the submount. Light emitting device dies having predefined patterns of conductive die attach material are also provided. Light emitting devices having a gallium nitride based light emitting region on a substrate, such as a silicon carbide substrate, may also be mounted in a flip-chip configuration by mounting an electrode of the gallium nitride based light emitting region to a submount utilizing a B-stage curable die epoxy. Light emitting device dies having a B-stage curable die epoxy are also provided.

摘要： LED lighting systems operate their LED above a junction temperature of 85° C. and space apart from the LED, components of the LED lighting system that reduce an expected lifetime of the LED lighting system to less than 25,000 hours as a result of operating the LED above the junction temperature of 85° C. Accordingly, the LED itself may be driven hotter than is conventionally the case, without impacting its lifetime. By allowing the LED to operate hotter, reduced heat sinking may be needed for the LED itself, which can decrease the cost, size and/or complexity of the thermal management system for the LED lighting system and/or can allow a thermal budget for the LED lighting system to be used elsewhere. Related structures are also described.
摘要翻译： LED照明系统将其LED的工作温度高于85°C，并与LED分开，LED照明系统的组件将LED照明系统的预期使用寿命降低到少于2.5万小时，因为LED的运行高于结温为85℃。因此，LED本身可以比常规情况下更热，而不影响其寿命。通过允许LED操作更热，LED本身可能需要减少散热，这可以降低LED照明系统的热管理系统的成本，尺寸和/或复杂性，和/或可以允许LED预算为 LED照明系统要在其他地方使用。还描述了相关结构。

摘要： A solid state lighting apparatus includes a plurality of light emitting diodes (LEDs) including at least a first LED and a second LED. Chromaticities of the first and second LEDs are selected so that a combined light generated by a mixture of light from the pair of LEDs has about a target chromaticity. The first LED may include a first LED chip that emits light in the blue portion of the visible spectrum and a phosphor that emits red light in response to blue light emitted by the first LED chip. The second LED emits light having a color point that is above the planckian locus of a 1931 CIE Chromaticity diagram, and in particular may have a yellow green, greenish yellow or green hue.
