  • Patent number: 6890234
    Abstract: A light source (10) includes a light emitting component (32), such as a UV/blue light emitting diode or laser diode coated with a layer (60) of a phosphor material (64). The phosphor material converts a portion of the light emitted by the light emitting component to light of a longer wavelength, such as yellow light. The thickness d of the layer varies across the light emitting component in relation to the intensity of light emitted by the light emitting component. This maintains a uniform color of the emission from the light source while minimizing the loss in light intensity (brightness) due to the presence of the phosphor.

A nickel and a gold film are formed on a portion of the copper film where the resist is not bonded. Next, an adhesive agent is applied onto a bottom of the lamp house so that the lamp house is bonded onto the substrate through the adhesive agent. A transparent epoxy resin is packed in the frame of the lamp house and hardened by heating to perform resin sealing. Since the resist is bonded onto the surface of copper having a large number of fine irregularities sufficient to ensure a large contact area and excellent in adhesion, separation can be prevented from being caused by thermal stress.

  • Patent number: 6578986
    Abstract: A modular light emitting diode (LED) mounting configuration is provided including a light source module having a plurality of pre-packaged LEDs arranged in a serial array. The module includes a heat conductive body portion adapted to conduct heat generated by the LEDs to an adjacent heat sink. A heat conductive adhesive tape connects the LED module to the mount surface. As a result, the LEDs are able to be operated with a higher current than normally allowed. Thus, brightness and performance of the LEDs is increased without decreasing the life expectancy of the LEDs. A plurality of such LED modules can be pre-wired together in a substantially continuous fashion and provided in a dispenser, such as a roll or box. Thus, to install a plurality of such LED modules, a worker simply pulls modules from the dispenser as needed, secures the appropriate number of modules in place, and connects the assembled modules to a power source.
