Method of fabrication for a light emitting diode substrate and a light emitting diode light source employing such substrate
An LED light source (10) comprises a ceramic substrate (20) with first and second opposed surfaces (30, 40). Pockets (50) are formed in the first surface (30) and each of the pockets includes a bottom (60) and a sidewall or sidewalls (70). A final electrical contact (105) comprised of a first electrically conductive material (57) with a coating of a second electrically conductive material (100) thereover is positioned in each of the pockets (50). An LED (110) is positioned in each of the pockets (50) and affixed to the electrical contact (105) and electrical connections (120), preferably in form of wire bonds, join the LEDs, the electrical connections (120) extending from a first LED (110) to an adjacent electrical contact (105). The ceramic substrate (20) is formed by injection molding a ceramic material and binder to form a green substrate (12) and subsequently sintering the green substrate to form the substrate (20). An LED light (150) can be formed from the LED light source (10) by adding a dome (150) formed of a ceramic material containing therein a homogeneous dispersion of a phosphor material capable of emitting light when excited by the light emitted from the operating LEDs (110).
