Abstract: A stellate beam splitter includes a light cavity for receiving a light source and a plurality of radial arms oriented around the light cavity, the plurality of radial arms oriented to concentrate light entering each of the plurality of radial arms at an end proximate to the light cavity and provide concentrated light at an end distal to the light cavity.

Abstract: A method for a user to select the color displayed by a multicolor LED device comprises a timed sequence display of color choices and sensing of a corresponding selection by user input.

Abstract: An inexpensive, lightweight, water-resistant, and aerodynamic lighting device securely mounts to the spokes of a bicycle wheel for improved safety and visibility of the bicycle and rider at night. No tools or other materials are required for installation or removal of the device.

Abstract: The dielectric casing of a light emitting diode (LED) incorporates an integral parabolic reflector system which redirects light in a collimated pattern deflected at significant angles relative to the axis of symmetry of the LED.

Abstract: A miniature switch module includes a battery harness attached to a circuit board. A diaphragm or pushbutton type switch and a battery are sandwiched between the retainer and circuit board.

Abstract: A personal illumination and safety device employs a flexible plastic rod to distribute the light of a light emitting diode (LED). A small container at one end of the flexible rod houses the LED, a battery and a switch which controls the illumination system. The flexible plastic rod allows the user to adapt the device to a variety of shapes and useful arrangements.

Abstract: A recreational or competitive flying disc includes an illumination system employing an array of flexible optical fibers to distribute the light of a single light emitting diode (LED) from the rotational center of the disc to its outside periphery. A small water-resistant compartment centered on the underside of the disc houses the LED, battery, and the illumination control. The leads of the LED also serve as the contacts of the battery. One end of each of the optical fibers is embedded in the LED, and the other end extends radially from the central housing on the underside surface of the disc to the rim of the disc. The flying disc is illuminated without altering the aerodynamic properties of the disc.
