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： 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.
