  • Patent number: 8366300
    Abstract: The invention is directed to an ornamental pond fish feeding indicator that has a housing with an indicator end. A first LED is enclosed in the housing at the indicator end of the housing. A second LED is also enclosed in the housing at the indicator end of the housing. A temperature sensing circuit is enclosed in the housing. The temperature sensing circuit transmits a signal to the first LED and the second LED. A float is attached to the housing. Using this invention, a pond owner can simply glance at his or her pond and determine whether or not to feed their fish based on the color of the light on top. The light on top of the indicator is red when pond water is below 50 degrees Fahrenheit. If the pond water is 50 degrees or over, the light is green.

  • Patent number: 8087810
    Abstract: Modular panels can be attached to a substratum, e.g. a wall or ceiling, to display an actively lighted star field. Each panel displays a respective subarea of the star field, the panels being attached onto the substratum in edgewise juxtaposed relationship according to the star field. Each panel defines a set of apertures extending through the panel and distributed over the panel according to the panel's respective subarea. On a back face of each panel is a set of light pipes respectively corresponding to the panel's set of apertures, each light pipe being illuminated by a light emitting diode. Panels can include twinkling stars, constant stars, and/or shooting stars, and energization of the corresponding light emitting diodes is constant or varied accordingly.

  • Patent number: 8033674
    Abstract: The present invention provides a polarization-sensitive light homogenizer and a backlight and display using the same. The homogenizer improves the spatial luminance and color uniformity, increases the luminance in a direction normal to the homogenizer and provides increased luminance through polarized light recycling within the light homogenizer and backlight. In one embodiment, the homogenizer includes a polarization-sensitive anisotropic light-scattering (PDALS) region, a non-polarization-sensitive anisotropic light-scattering region, and a substantially non-scattering region. In a further embodiment, the non-scattering region is birefringent. The spatially non-uniform incident light flux from a backlight including one or more non-extended light emitting sources is scattered efficiently by the NPDASL region and is incident on the PDALS region which backscatters light orthogonal to the polarization state desired for efficient illumination of a liquid crystal display panel.

  • Patent number: 8021016
    Abstract: A mounting system and method for a light source includes a light source support structure. The light source support structure positions the light source with respect to a source of electrical power which, when connected to the light source, will cause the light source to emit light energy. Further included in the mounting system and method of present invention is a mounting for a pair of electrical contacts which enable connection between the source of electrical power and the light source. Still further included in mounting system is a heat sink which is attachable to the light source support structure for conducting heat energy away from the light source.

  • Patent number: 8021021
    Abstract: Systems and methods permit use of efficient solid state emitters for broad spectrum continuous spectrum lighting defined by illumination data. The illumination data, which can be sold as a commercial product, can be recorded or authored and include spectral, temporal, and spatial information. Intensities of individual emitters such as LEDs can be controlled through a combination of pulse width modulation (PWM) and amplitude modulation (AM) of drive currents. The combination of PWM and AM permits fine tuning of the spectrum of emissions and creation of free space optical data channels.

  • Patent number: 8016466
    Abstract: A reflector 30 is constituted as an aspherical mirror that forms a light distribution S1 in which spread of reflected light in a longitudinal direction of the vehicle is larger than spread of reflected light in a lateral direction of the vehicle. The light distribution expanded in the longitudinal direction of a vehicle 3 makes the light less likely to impinge on a side surface of the vehicle 3, so that the rear part of the vehicle 3 can be illuminated efficiently. As a result, maximum illumination can be achieved with the minimum amount of light. In addition, because the range of illumination is long in the longitudinal direction, not only the area around an occupant's feet outside a front door 5 but also an area around the feet outside a rear door 6 can be illuminated easily.
