  • Publication number: 20130207126
    Abstract: A method for manufacturing an optoelectronic apparatus includes attaching bottom surfaces of first and second packaged optoelectronic semiconductor devices (POSDs) to a carrier substrate (e.g., a tape) so that there is a space between the first and second POSDs. An opaque molding compound is molded around portions of the first and second POSDs attached to the carrier substrate, so that peripheral surfaces of the first POSD and the second POSD are surrounded by the opaque molding compound, the space between the first and second POSDs is filled with the opaque molding compound, and the first and second POSDs are attached to one another by the opaque molding compound. The carrier substrate is thereafter removed so that electrical contacts on the bottom surfaces of the first and second POSDs are exposed. A window for each of the POSDs is formed during the molding process or thereafter.

  • Patent number: 8500297
    Abstract: A light emitting diode module is produced using at least one LED and at least two selectable components that form a light mixing chamber. First and second selectable components have first and second types of wavelength converting materials with different wavelength converting characteristics. The first and second wavelength converting characteristics alter the spectral power distribution of the light produced by the LED to produce light with a color point that is a predetermined tolerance from a predetermined color point. Moreover, a set of LED modules may be produced such that each LED module has the same color point within a predetermined tolerance. The LED module may be produced by pre-measuring the wavelength converting characteristics of the different components selecting components with wavelength converting characteristics that convert the spectral power distribution of the LED to a color point that is a predetermined tolerance from a predetermined color point.

  • Patent number: 8497516
    Abstract: Although an organic resin substrate is highly effective at reducing the weight and improving the shock resistance of a display device, it is required to improve the moisture resistance of the organic resin substrate for the sake of maintaining the reliability of an EL element. Hard carbon films are formed to cover a surface of the organic resin substrate and outer surfaces of a sealing member. Typically, DLC (Diamond like Carbon) films are used as the carbon films. The DLC films have a construction where carbon atoms are bonded into an SP3 bond in terms of a short-distance order, although the films have an amorphous construction from a macroscopic viewpoint. The DLC films contain 95 to 70 atomic % carbon and 5 to 30 atomic % hydrogen, so that the DLC films are very hard and minute and have a superior gas barrier property and insulation performance.

  • Patent number: 8492788
    Abstract: Certain example embodiments of this invention relate to techniques for improving the performance of Lambertian and non-Lambertian light sources. In certain example embodiments, this is accomplished by (1) providing an organic-inorganic hybrid material on LEDs (which in certain example embodiments may be a high index of refraction material), (2) enhancing the light scattering ability of the LEDs (e.g., by fractal embossing, patterning, or the like, and/or by providing randomly dispersed elements thereon), and/or (3) improving performance through advanced cooling techniques. In certain example instances, performance enhancements may include, for example, better color production (e.g., in terms of a high CRI), better light production (e.g., in terms of lumens and non-Lambertian lighting), higher internal and/or external efficiency, etc.

  • Patent number: 8476657
    Abstract: To provide a light emitting device easy to produce and extracting light to its outside with high efficiency, the light-emitting device 70 of the present invention includes an insulating base 10; a light-emitting element 1 mounted on a side of the base 10; and a protection element 2 mounted on the side and protecting the light-emitting element 1. The element 2 is covered with a light-reflecting filler-containing resin 5, which is prepared by causing a flexible silicone resin to contain, before being cured, light-reflecting or light-scattering fillers 5a having a particle diameter larger than the wavelength of light emitted by the element 1. This causes light emitted from the element 1 to be reflected by the resin 5, instead of being absorbed by the element 2, so that such light is released to the outside of the light-emitting device 70. This allows the device 70 to extract light to the outside with high efficiency, and also allows for easy formation of the resin 5 having a desired pattern and position.
