    Abstract: A light source and method for making the same are disclosed. The light source includes a plurality of Segmented LEDs connected in parallel to a power bus and a controller. The power bus accepts a variable number of Segmented LEDs. The controller receives AC power and provides a power signal on the power bus. Each Segmented LED is characterized by a driving voltage that is greater than 3 times the driving voltage of a conventional LED fabricated in the same material system as the Segmented LED. The number of Segmented LEDs in the light source is chosen to compensate for variations in the light output of individual Segmented LEDs introduced by the manufacturing process. In another aspect of the invention, the number of Segmented LEDs connected to the power bus can be altered after the light source is assembled.

    Abstract: An optical device capable of illuminating visual light with adjusting color temperature after fabrication is disclosed. The optical device includes a solid state light emitter and a phosphor layer, which is formed over the solid state light emitter. The solid state light emitter, which can be a light emitter diode (“LED”), converts electrical energy to blue light. The phosphor layer subsequently converts first light with a first wavelength to second light with a second wavelength. In one example, the first light is blue light while the second light is white light. A portion of the phosphor layer is adjusted after the phosphor layer is formed for adjusting color of the white light in accordance with color quality of the light detected by a light detector.

  • Publication number: 20090168406
    Abstract: Light-emitting elements are divided into chromaticity groups on the basis of their chromaticity. In a planar light source, light-emitting elements selected from two of the chromaticity groups are alternately provided in a longitudinal direction and in a transverse direction, respectively. The two chromaticity groups are substantially equally away from a target chromaticity in directions reverse to each other. Further, pairs of two of the light-emitting elements belonging to the two chromaticity groups which are separated from each other, are provided so that distances d2 at which two of the light-emitting elements in each of the pairs are provided are less than distances d1 at which the pairs are provided.

  • Publication number: 20090147501
    Abstract: The present invention provides a backlight module and a manufacture method thereof using complementary light sources having the same color. The backlight module includes an optical film set and a plurality of light source sets having a first light source and a second light source. The first light source generates a first chromaticity light while the second light source generates a second chromaticity light. The first chromaticity light mixes with the second chromaticity light in the space between the light source sets and the optical film set and then enters the optical film set. The first chromaticity light and the second chromaticity light have their own spectrum and both spectra fall into a first color region of the CIE 1931 color space. Within the first color region, the spectrum of the first chromaticity light is close to a second color region while the spectrum of the second chromaticity light is close to a third color region.

  • Publication number: 20090134415
    Abstract: A light scattering section is formed on at least part of a surface of a sealing resin section including fluorescent bodies and covering light emitting diode chips. Light from the light emitting diode chips is scattered by the light scattering section, and then is returned to the sealing resin section so as to excite the fluorescent bodies so that fluorescence is generated. Part of the light to be emitted outside a light emitting element from the light emitting diode chips returns to the sealing resin section so that chromaticity of the light is converted by the fluorescent bodies, thereby adjusting a chromaticity variation among the light emitting elements. In this way, the chromaticity variation among the light emitting elements can be adjusted.
