摘要： Standardized photon building blocks are packaged in molded interconnect structures to form a variety of LED array products. No electrical conductors pass between the top and bottom surfaces of the substrate upon which LED dies are mounted. Microdots of highly reflective material are jetted onto the top surface. Landing pads on the top surface of the substrate are attached to contact pads disposed on the underside of a lip of the interconnect structure. In a solder reflow process, the photon building blocks self-align within the interconnect structure. Conductors in the interconnect structure are electrically coupled to the LED dies in the photon building blocks through the contact pads and landing pads. Compression molding is used to form lenses over the LED dies and leaves a flash layer of silicone covering the landing pads. The flash layer laterally above the landing pads is removed by blasting particles at the flash layer.

摘要： A street light includes a pole and a head attached to the pole. The head includes a light emitting element comprising a plurality of solid state light emitting devices, an optical element, and a reflector configured to reflect light emitted by the solid state light emitting devices to the optical element to produce a light distribution pattern from the head. The light emitted from the solid state emitting devices may be Lambertian patterned light. The Lambertian patterned light may be used to illuminate the reflector. The reflector may be used to transform the Lambertian patterned light to collimated light and direct the collimated light towards the optical element. The optical element may be configured to produce the light distribution pattern from the collimated light.

摘要： Light emitting assemblies comprise a plurality of Light Emitting Diode (LED) dies arranged and attached to common substrate to form an LED array having a desired optimum packing density. The LED dies are wired to one another and are attached to landing pads on the substrate for receiving power from an external electrical source via an interconnect device. The assembly comprises a lens structure, wherein each LED die comprises an optical lens disposed thereover that is configured to promote optimal light transmission. Each optical lens has a diameter that is between about 1.5 to 3 times the size of a respective LED die, and is shaped in the form of a hemisphere. Fillet segments are integral with and interposed between the adjacent optical lenses, and provide sufficient space between adjacent optical lenses so that the diameters of adjacent optical lenses do not intersect with one another.

摘要： A linear lighting module includes a first string of series-connected LED dies and a second string of series-connected LED dies. The first string of LED dies is coupled in parallel with the second string of LED dies. All of the LED dies of the first and second strings are aligned with respect to one another. The LED dies of the first string and the second string form a combined string of interleaved LED dies such that an LED die of the second string is disposed between every successive pair of LED dies of the first string. The LED dies of the combined string are mounted on a flexible substrate. Each LED die of the combined string is electrically connected to two conductors. Except for the two end LED dies of the combined string, each successive LED die must be accessed by both conductors from alternating sides of the combined string.

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.
