  • Publication number: 20200095430
    Abstract: A versatile silicone resin reflective substrate which exhibits high reflectance of high luminance light from an LED light source over a wide wavelength from short wavelengths of approximately 340-500 nm, which include wavelengths from 380-400 nm near lower limit of the visible region, to longer wavelength in the infra-red region. The silicone resin reflective substrate has a reflective layer which contains a white inorganic filler powder dispersed in a three-dimensional cross linked silicone resin, the inorganic filler powder having a high reflective index than the silicone resin. The reflective layer is formed on a support body as a film, a solid, or a sheet. The silicone resin reflective substrate can be easily formed as a wiring substrate, a packaging case or the like, and can be manufactured at low cost and a high rate of production.

  • Patent number: 9803829
    Abstract: A lens for light emitting lamps that use light emitting elements such as LEDs, etc., is provided. The lens has a specific surface shape for light-distribution control to achieve desired light distributions, as well as a light emitting device using said lens. On the lens surface of the light emitting side which has a double-peak shape to obtain a light distribution characteristic having long and short two axes, by possessing a straight-line part in the surface shape of the light emitting side viewed on the lens short-axis cross section, a desired smoothly-diffused light distribution having a longitudinal direction with a certain width is obtained. The lens may be designed to have a surface of the light emitting side comprising a collection of straight lines parallel to the lens short-axis cross section, or to have a continuous curved surface comprising a collection of straight lines parallel to the lens short axis.
