  • Patent number: 7503670
    Abstract: A novelty flashlight in the form of a sparkplug, with a set of LEDs (or other appropriate light emitting devices) included in the conventional “spark” emitting end of the plug. A battery source and micro-controller are included within the sparkplug housing and used to turn the LEDs “on” and “off”. In particular, the LEDs may be controlled to strobe at a rate that simulates the actual sparking of an automotive sparkplug. Alternatively, the pulsing of the LEDs may be fast enough such that the LEDs appear to be always “on”. An activation button is included on the outer housing the sparkplug for a user to control the operation of the flashlight.

  • Patent number: 7500769
    Abstract: A front lighting device for a vehicle includes a speed detection unit for detecting a vehicle speed, a steering angle detection unit for detecting a steering angle, and a swivel angle determination unit. The swivel angle determination unit determines a swivel angle based only on the detected steering angle when the detected speed is within a first speed range, and based on both the detected steering angle and the detected speed when the detected speed is within a second speed range which is higher than the first speed range. An actuator controls a direction of light from a head light of the vehicle, so that the direction of the light changes in accordance with the determined swivel angle.

  • Patent number: 7500765
    Abstract: A light fixture allows individual light bulbs to be arranged in compact fashion to maximize the number of bulbs per given area in the fixture. To facilitate replacement or exchange of the bulbs, the bulbs are mounted in alternating succession on a pair of separately movable supports, reorientation of which serves to remove the bulbs from the tight packed arrangement, to one in which the bulbs are sufficiently separated from one another to allow hand access for removal and installation of the bulbs. A distinct aspect of the aforementioned feature of the invention independent of the movable supports resides in the ability to utilize two of more of the fixtures to multiply the light produced. Advantageously, the fixtures can be arranged in direct physical series, side by side, or to form an array extending in orthogonal directions.

  • Patent number: 7494246
    Abstract: High power white light LEDs are distributed within a thin reflective cavity. The cavity depth may be less than 3 cm and, in one embodiment, is about 1 cm. A light output surface of the cavity is a flat reflector with many small openings. A small plastic lens is positioned over each opening for causing the light emitted from each opening to form a cone of light between approximately 50-75 degrees. Alternatively, each hole may be shaped to be a truncated cone to control the dispersion. The light emitted by the LEDs is mixed in the cavity by reflecting off all six reflective walls of the cavity. The light will ultimately escape through the many holes, forming a relatively uniform pattern of light on a surface to be illuminated by the luminaire.

  • Patent number: 7484869
    Abstract: To improve visibility by expanding a light emitting range without increasing a size of a light source, in a lighting unit for a vehicle using a projector lamp. A front light has a projector lamp arranged behind an outer lens. A light guiding body is provided from a side surface of the projector lamp to the front. A front surface of the light guiding body emits light along a bottom surface of the front light. A first reflector and a second reflector constituting an isolated extension section extending upwards are arranged opposite to each other holding a distance between them, at a side surface of the projector lamp. The periphery of the first reflector extends out slightly more than the second reflector to form a fringe light emitting section. This causes emission of light of the light guide path in a fringe shape.
