  • Patent number: 8530883
    Abstract: Light emitting devices comprise excitation sources arranged to excite quantum dots which fluoresce to emit light. In an embodiment, a device is manufactured by a process which involves applying an acoustic field is applied to a fluid containing quantum dots, to cause the quantum dots to accumulate at locations which are adjacent to excitation sources, and then initiating a phase transition of the fluid to trap the quantum dots in the locations adjacent to the excitation sources. The quantum dots are illuminated during the process and the resulting fluorescence is optically monitored to provide indicators of quantum dot distribution in the fluid. These indicators are used as feedback for controlling aspects of the process, such as initiating the phase transition.

  • Patent number: 8525217
    Abstract: A device for resin coating is used for producing an LED package including an LED element covered with resin containing phosphor. In a state in which a trial coating material 43 is located by a clamp unit 63, a trial coating of resin applied to the trial coating material 43 is irradiated with excitation light and light emitted from the phosphor contained in the resin is measured by an emission characteristic measuring unit 39. A deviation of the measurement result of the emission characteristic measuring unit from a prescribed emission characteristic is determined, and then a proper amount of resin to be applied to the LED element is derived for actual production based on the deviation.

  • Publication number: 20130221380
    Abstract: A method for manufacturing a plurality of optoelectronic apparatuses include attaching bottom surfaces of a plurality of packaged optoelectronic semiconductor devices (POSDs) to a carrier substrate (e.g., a tape) so that there is a space between each POSD and its one or more neighboring POSD(s). A light reflective molding compound is molded around a portion each of the POSDs attached to the carrier substrate so that a reflector cup is formed from the light reflective molding compound for each of the POSDs. The light reflective molding compound can also attach the POSDs to one another. Alternatively, an opaque molding compound can be molded around each POSD/reflector cup to attach the POSDs/reflector cups to one another and form a light barrier between each POSD and its neighboring POSD(s). The carrier substrate is thereafter removed so that electrical contacts on the bottom surfaces of the POSDs are exposed.
