摘要: A method to make light-emitting diode (LED) units include arranging LEDs in a pattern, forming an optically transparent spacer layer over the LEDs, forming an optically reflective layer over the LEDs, and singulating the LEDs into LED units. The method may further include, after forming the optically transparent spacer layer and before singulating the LEDs, forming a secondary light-emitting layer that conforms to the LEDs, cutting the LEDs to form LED groups having a same arrangement, spacing the LED groups on a support, and forming the optically reflective layer in spaces between the LED groups.

摘要: Systems for apparatuses formed of light emitting devices. Solutions for controlling the off-state appearance of lighting system designs is disclosed. Thermochromic materials are selected in accordance with a desired off-state of an LED device. The thermochromic materials are applied to a structure that is in a light path of light emitted by the LED device. In the off-state the LED device produces a desired off-state colored appearance. When the LED device is in the on-state, the thermochromic materials heat up and become more and more transparent. The light emitted from the device in its on-state does not suffer from color shifting due to the presence of the thermochromic materials. Furthermore, light emitted from the LED device in its on-state does not suffer from attenuation due to the presence of the thermochromic materials. Techniques to select and position thermochromic materials in or around LED apparatuses are presented.

摘要: Embodiments of the invention include a semiconductor light emitting diode (LED) attached to a top surface of a mount. A multi-layer reflector is disposed on the top surface of the mount adjacent to the LED. The multi-layer reflector includes layer pairs of alternating layers of low index of refraction material and high index of refraction material. A portion of the top surface in direct contact with the multi-layer reflector is non-reflective.

摘要: Light emitting die (300) comprising a plurality of light emitting elements (310A, 310B), each having a pair of bond pads (N1,P1 and N2,P2), wherein at least two diagonally opposite bond pads of adjacent light emitting elements on a die have their facing corners truncated (330) to enable a direct diagonal coupling of a complementary pair of diagonally opposite bond pads when the die is monted on a substrate on which an interconnection pattern is formed. By enabling diagonal as well as lateral coupling of the bond pads of multiple light emitting elements of a die, the multiple light emitting elements may be arranged in a variety of series and/or parallel configurations, thereby facilitating the use of the same die at different nominal operating voltages with a single inter-connect layer on the substrate upon which the die is mounted.

摘要: A semiconductor light emitting device (100;200;300;400,400B,400C;500;600;700) may have a reflective side coating (120;220;320;420;520;620;720) disposed on a sidewall (118;215;315;415,435;515) of a semiconductor light emitting device structure. Such a device may be fabricated by dicing a semiconductor structure to separate a semiconductor light emitting device structure and then forming a reflective side coating (120;220;320;420;520;620;720) on a sidewall (118;215;315;415,435;515) of the separated semiconductor light emitting device structure.
