发明名称 Method and apparatus for providing high-temperature multi-layer optics
摘要 A solid-state light-emitting device (“SLD”) converting electrical energy to photon energy using a light emitter diode (“LED”) and high-temperature multi-layer optics (“HMO”) is disclosed. The SLD, in one aspect, includes a chip-on-board (“COB”), a silicone inner layer (“SIL”), and a Poly methyl methacrylate (“PMMA”) layer. The COB includes a first surface and a second surface wherein the first surface includes at least one LED. The LED converts electrical energy to optical light and the light subsequently leaves the LED becoming visible light. The SIL includes a first silicone surface and a second silicone surface wherein the second silicone surface is in contact with the first surface of COB and the second silicone surface is in contact with the PMMA layer. The operating temperature of PMMA layer is lower than the operating temperature of SIL.

主权项 1. A light-emitting device, comprising: a chip-on-board (“COB”) having a first surface and a second surface and containing at least one light emitter diode (“LED”) situated adjacent to the first surface, the COB configured to emit optical light from the LED passing through the first surface; a silicone inner layer (“SIL”), having a first operating temperature, a first silicone surface, and a second silicone surface, wherein the second silicone surface of the SIL is disposed on the first surface of the COB; and a Poly methyl methacrylate (“PMMA”) layer, having a second operating temperature, an inner surface, and an outer surface, wherein the inner surface of the PMMA layer is disposed on the first silicone surface of SIL, wherein the first operating temperature has a higher operating temperature than the second operating temperature.
