摘要： There is provided a light emitting device, for example a grow-light, comprising: a first solid-state light source that generates blue light with a blue photon flux; and a second solid-state light source that generates red light with a red photon flux; wherein a ratio of the blue photon flux to red photon flux is from about 1:3 to about 3:1. It may be that the broadband blue light substantially matches at least one of: the absorption peak wavelength of chlorophyll-a; the absorption peak wavelength of chlorophyll-b; and the absorption peak wavelength of carotenoid.

摘要： A light source that is adapted to replace existing fluorescent tubes in an existing fluorescent light fixture is disclosed. The light source includes a plurality of LEDs mounted on a heat-dissipating structure, first and second plug adapters that mate with the florescent tube connectors of the fluorescent tube the light source is to replace, and a power adapter that converts power from a fluorescent tube ballast presented on the first and second plug adapters to DC power that powers the LEDs. The light source is powered from the output of the existing fluorescent ballast. The light source can utilize the existing metallic enclosure as a heat-radiating surface and/or direct air heat transfer from the surface of the heat-dissipating structure.

摘要： A lighting system that is part of a headlight module of a motor vehicle includes an array of LED light sources that include no organic materials. Each light source includes a glass lens attached to a phosphor glass converter plate, which itself is attached to an LED die that is flip-chip mounted on a mounting substrate. The converter plate includes phosphor particles embedded in glass. Each lens is disposed laterally over a single LED die. The converter plate is attached to the LED die by a first bonding layer, and the lens is attached to the converter plate by a second bonding layer. Both bonding layers are made of a metal oxide and are thinner than the converter plate. Either each lens does not extend horizontally outside the lateral boundary of each converter plate, or the lens portions centered on each LED die are part of a unitary lens array.

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： Light emitting diode (LED) constructions comprise an LED having a pair of electrical contacts along a bottom surface. A lens is disposed over the LED and covers a portion of the LED bottom surface. A pair of electrical terminals is connected with respective LED contacts, are sized larger than the contacts, and connect with the lens material along the LED bottom surface. A wavelength converting material may be interposed between the LED and the lens. LED constructions may comprise a number of LEDs, where the light emitted by each LED differs from one another by about 2.5 nm or less. LED constructions are made by attaching 2 or more LEDs to a common wafer by adhesive layer, forming a lens on a wafer level over each LED to provide a rigid structure, removing the common wafer, forming the electrical contacts on a wafer level, and then separating the LEDs.

摘要： An LED CoB structure with the combination use of blue and red LED dies is used to achieve warm white light, with good quantum conversion efficiency at a reasonably low cost. Both the red and blue LED dies are fabricated on transparent substrates. The current density of the LED dies is designed to match the different degradation rate of each type of LED die. The methods used to achieve high efficiency include adjusting the power, wavelength, and/or position of the dies.
