摘要: Surface mount light emitting diode (LED) packages each contain a light emitting diode (LED) die (24). A plurality of arrays of openings are drilled into an electrically insulating sub-mount wafer (10). A metal is applied to the drilled openings to produce a plurality of via arrays (12). The LED dice (24) are flip-chip bonded onto a frontside (16) of the sub-mount wafer (10). The p-type and n-type contacts of each flip-chip bonded LED (24) electrically communicate with a solderable backside (18) of the sub-mount wafer (10) through a via array (12). A thermal conduction path (10, 12) is provided for thermally conducting heat from the flip-chip bonded LED dice (24) to the solderable backside (18) of the sub-mount wafer (10). Subsequent to the flip-chip bonding, the sub-mount wafer (10) is separated to produce the surface mount LED packages.

摘要: An LED device including an LED chip and a lens positioned apart from the chip and coated with a uniform thickness layer of fluorescent phosphor for converting at least some of the radiation emitted by the chip into visible light. Positioning the phosphor layer away from the LED improves the efficiency of the device and produces more consistent color rendition. The surface area of the lens is preferably at least ten times the surface area of the LED chip. For increased efficiency, the reflector and submount can also be coated with phosphor to further reduce internal absorption.
