  • Light wavelength conversion unit
    Patent number: 9121576
    Abstract: In a light wavelength conversion unit, a light wavelength conversion member is placed on the emission surface of a semiconductor light-emitting element. The light wavelength conversion member converts the wavelength of blue light, which has emitted from the semiconductor light-emitting element and entered from an incident surface, so as to emit yellow light and then emits the yellow light from an emission surface. A light reflection layer is provided on a lateral face in the surface of the light wavelength conversion member. Here, the lateral face excludes the incident surface and the emission surface. The light wavelength conversion member is roughened such that an average roughness Ra of the lateral face is 0.5 ?m or above.

  • Light emitting module
    Patent number: 9054280
    Abstract: In a light emitting module, a red phosphor is contained in a second phosphor layer so that the wavelength of a second phosphor layer after the wavelength conversion is longer than that of a first phosphor layer. And a blue phosphor and a yellow-green phosphor are contained in the first phosphor layer. The first phosphor layer is formed in an illumination area of light emitted from an LED chip, and the first phosphor layer converts the wavelength of the light from the LED chip and emits the wavelength-converted light from an emission surface. A part of the second phosphor layer is formed in a non-direct area where no light is illuminated from the LED chip and where light is illuminated from the first phosphor layer. The part of the second phosphor layer formed in the non-direct illumination area converts the wavelength of the light emitted from the first phosphor layer.
