A reflector for backlighting an indicating instrument has two groups of flutes arranged for evenly distributing light and reducing bright spots. A plate has a recessed portion for receiving the indicating instrument and a semi-bowl-shaped compartment extending away from the plate and opening to the indicating instrument. The compartment has a base with a central projection formed by parabolic flutes and a semi-circular wall connecting the base with the recessed portion of the plate. The semi-circular wall has an inner surface facing the parabolic flutes. The inner surface has flutes extending in a radial direction from the base. Two apertures are positioned in the compartment across a boundary between the base and semi-circular wall. The apertures each receive a light emitting diode mounted on a printed circuit board when the board is assembled on the reflector. The parabolic flutes distribute the light from the light emitting diodes to evenly backlight the indicating instrument. The radial flutes diffuse the light to prevent hot or bright spots from developing under the indicating instrument. The light is further scattered by a chrome coating applied on a surface of the indicating instrument facing the compartment.
A vehicular lighting housing utilizes a combination of a two-way mirror, a strip of multi-color LEDs, and a one-way mirror spaced from the two-way mirror, such that when the LEDs are illuminated, light reflects back and forth between the two-way mirror and the one-way mirror to present a series of constantly converging light streams forming an endless tunnel of light. A control switch connected to the LEDs and a battery has a rheostat control, a toggle switch and a push button switch to enable the LEDs to be selectively displayed in steady, flashing and paint modes.
A lighting apparatus. The lighting apparatus comprises a light source, a hollow hollow module, and a rectangular lens. The hollow module has a concave, a opening, and an inner reflective surface. The light source is disposed in the concave. The rectangular lens with a semi-translucent incident surface and a display surface is seated in the opening. Light rays emitted from the light source are reflected by the inner surface. Subsequently, the light rays enter the incident surface and exit the lens through the display surface.
A reflector provides different-colored backlighting to indicia and a background field of an instrument dial. The dial is mounted on a reflector, forming an interior space. The reflector is assembled on a printed circuit board (PCB). A recessed section of the reflector has an opening exposing a portion of the PCB to the interior space. Another section of the reflector provides a short tube having an inner cavity suspended over the opening. A first group of light emitting diodes is mounted on the exposed portion of the PCB under the tube such that light from the first group is reflected through the inner cavity to light a pointer. A second group of light emitting diodes having a different color is mounted outside the tube and backlights the indicia of the dial. A gap between the exposed portion of the PCB and an end of the tube enables light to leak from the inner cavity and backlight the background field of the dial a different color than the indicia.
A lamp (8, 108, 208) includes a reflector (10, 110, 210) with a plurality of off-axis reflector segments (20, 22, 24, 120a, 120b, 220). Each off-axis reflector segment has a focus at a perimeter (12, 112, 112a, 112b, 212) of the reflector. A plurality of light emitting elements (40, 42, 44, 140a, 140b, 240) are disposed at the foci of the off-axis reflector segments.
A vehicular lighting housing utilizes a combination of a two-way mirror, a strip of LEDs, a one-way mirror spaced from the two-way mirror, and a cover glass such that when the LEDs are illuminated, light reflects back and forth between the two-way mirror and the one-way mirror to present a series of constantly converging light streams forming an endless tunnel of light.
