Patent number: 7249874Abstract: 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.Type: GrantFiled: December 30, 2005Date of Patent: July 31, 2007Assignee: Kuhl Reflections, Inc.Inventor: Larry Kuhl

Patent number: 7172296Abstract: In order to minimize light diffraction along the direction of switching and more particularly light diffraction into the acceptance cone of the collection optics, in the present invention, micromirrors are provided which are not rectangular. Also, in order to minimize the cost of the illumination optics and the size of the display unit of the present invention, the light source is placed orthogonal to the rows (or columns) of the array, and/or the light source is placed orthogonal to a side of the frame defining the active area of the array. The incident light beam, though orthogonal to the sides of the active area, is not however, orthogonal to any substantial portion of sides of the individual micromirrors in the array. Orthogonal sides cause incident light to diffract along the direction of micromirror switching, and result in light ‘leakage’ into the ‘on’ state even if the micromirror is in the ‘off’ state. This light diffraction decreases the contrast ratio of the micromirror.Type: GrantFiled: May 28, 2004Date of Patent: February 6, 2007Assignee: Reflectivity, IncInventor: Andrew G. Huibers

Patent number: 7099065Abstract: A spatial light modulator is disclosed, along with methods for making such a modulator that comprises an array of mirror devices each having at least a first electrode and a second electrode. The first electrode is designated for driving the mirror plate of the micromirror device to an ON state, and the second electrode is designated for driving the mirror plate to an OFF state. The two electrodes can be disposed on the same side of the mirror plate but on opposite sides of the rotation axis of the mirror plate for driving the mirror plate to rotate in opposite directions. Alternatively, the two electrodes can be disposed on the opposite sides of the mirror plate, but on the same side of the rotation axis of the mirror plate for driving the mirror plate to rotate in opposite directions. The ON state and OFF state of the mirror plate can be defined by stops.Type: GrantFiled: May 13, 2003Date of Patent: August 29, 2006Assignee: Reflectivity, Inc.Inventors: Satyadev Patel, Andrew G.
