SUMMARY OF THE INVENTION

The present invention is a new technology side marker light for all types of motor vehicles. This new and unique side marker light is created and designed to be mounted recessed into a vehicle side panel, and to conform to the outside contour of the vehicle side panel, rather than be mounted onto the out-side of a vehicle.

The objective of this new invention is the advancement of the art of forming side marker lights using a combination of optically conductive acrylic or other plastic, light emitting diodes in several different configurations, (herein after LEDs), insertion plastic injection molding, injection molding, and ultrasonic welding.

A first component of a first embodiment of this new technology side marker lighting is formed by an insertion injection molding process. A reflective surfaced electrically non-conductive strip of mounting board with red and amber LEDs mounted alternately at intervals along a first side of said reflective board, and electrical connectivity for said LEDs beneath said reflective surface or coating, is placed longitudinally inside of a mold into which optically conductive acrylic or other plastic is injected. Said injection mold is constructed to form end-to-end “V” shaped longitudinal depressions into the outside facing surface of said molded acrylic first component. Triangular shapes, or any other shape or surface distortion that will diffuse light directed toward said outside facing surface from said imbedded LEDs may be also be molded.

A second component for said first embodiment of side marker light is a UVa and UVb resistant polycarbonate cover that is injection molded with an inside surface that conforms exactly to the longitudinally ribbed outside surface of said first component. The outside surface of said second component polycarbonate cover is shaped to conform to the particular vehicle panel surface contour into which it will be mounted, and said outside surface of said second component may be clear or frosted. Said second component polycarbonate cover is then ultrasonically welded onto the ribbed outside surface of said first component to form a one piece optically clear or frosted white, side marker light. Said electrical connectivity of said first embodiment of this new side marker lighting is designed to electrically connect all of the red LEDs in a series, series parallel, or parallel connection as desired. All of the amber LEDs are electrically connected in like manner.

The insertion plastic injection molding of said first component, and the injection molding of the polycarbonate cover of said second component could be a combined process that eliminates the need for ultrasonic welding or other means to combine the two components. The polycarbonate cover may remain a separate tight fitting second component that is snapped into place, glued, mechanically fastened, or held in position as a cover on said first component by any means.

A second embodiment of this instant invention utilizes a double sided reflective surfaced electrically non conductive strip of mounting board that has red and amber LEDs mounted alternately along a first side of said mounting strip, and white and/or other colored LEDs mounted along a second side of said mounting strip. The width of the opening in the vehicle side panel for said side light would be narrower than the reflective surface of the LED mounting board within said sidelight so that light from a first side of said sidelight is not visible through the illumination device from a second side, and light from a second side is not visible through the illumination device from a first side. The electrical connectivity of said double-sided strip of LEDs requires four or more electrical conductors. A first conductor would supply positive power to said outside red LEDs. A second conductor would supply positive power to said outside amber LEDs. A third conductor would supply power to said inside white LEDs. A fourth conductor would supply power to any other colored inside LEDs. A fifth and/or sixth conductors would supply common or negative to all LEDs. Said first side of said second version of this instant invention will illuminate the outer surface of said illumination device with red or amber light as required to cooperate with the vehicle lighting system, and said second side will illuminate the storage or cargo area of a truck, automobile trunk, wheel well, or engine compartment, with white or colored light when said second side LEDs are electrically powered on. Said second side may be covered permanently or temporarily by a colored plastic lens or cover to change the white inside illumination to any selectable or desired color. Said cover may use snap-fit or press fit retention, or be attached by any other means.

A third embodiment of this instant invention is formed by placing two single sided reflective LED mounting strips into an injection mold with a first strip inserted just above the bottom of the mold with the LEDs facing in an upward direction. A pre-made reflective surface is inserted into said mold that extends substantially from a first end to a second end of said mold. The reflective surface bottom side or edge is placed toward the back of the mold beyond the back edge of said first LED mounting strip. The topside of said reflective surface is positioned toward the front of said mold. A second LED-mounting strip with the LEDs facing in a downward direction is inserted just below the top of the mold and behind the top edge of the reflective strip. The diagonal placement of the reflective surface causes illumination from the bottom mounted LEDs to reflect in a forward direction, and illumination from the top mounted LEDs to reflect in a back direction. i.e. Light from the bottom LED strip aimed in an upward direction will be reflected generally at a right angle toward the front surface of this first component, and light aimed in a downward direction from said second LED mounting strip will be reflected generally at right angles to the source toward the back surface of said first component.

One or more individual LEDs, or cluster LEDs, may then be inserted into said mold, at one or more ends of said mold, facing toward the opposite end of said mold. Said one or more LEDs are placed beneath the ends of the top LED-mounting strip and above the ends of the bottom LED-mounting strip. End light from said individual or cluster LEDs will be directed out of said first component as side light by said reflective surface. Optically conductive acrylic or other plastic is then injected into said mold locking all of said LED components, electrical conductors, and said reflector into position. Said mold will create rows of V shaped illumination diffusing indentations from end to end on the front surface of said first component.

In vehicle panel locations where the first or second embodiment of this sidelight instant invention cannot be completely mounted between an inner and outer panel of the vehicle wall, or the wall is a single panel, such as a fender wall over a wheel well, an inside bracket or housing may be required to support said side light. Said inside support bracket will require an elongated opening to allow illumination from said back surface of said second version said side light to be visible.

The first embodiment of this instant invention as described in the objective of the invention is used as a new two-color side marker light system mounted within an elongated cavity or opening in a vehicle sidewall or panel. This acrylic illumination device would be mounted within the cavity so that the outer illumination device surface would be flush or nearly flush with the outer surface of the vehicle side panel and conform to the shape or contour of said panel. The illumination of the amber and red LEDs would cooperate with the vehicle illumination system in a manner consistent with the National Highway Traffic Safety Administration Federal Motor Vehicle Standard No. 108.

The second embodiment of this instant invention is mounted within a side wall of a pick up truck cargo area so that a first side of said combination illumination device is approximately flush with the outside panel, and a second side of said combination illumination device is approximately flush with the inside panel or wall of said cargo area. Said first side of said illumination device would cooperate with said vehicle signal lights and said second side would be electrically switch controlled to illuminate the cargo area of said truck with white light not visible through said illumination device from the outside of said truck.

The second or third embodiment of said illumination device can be mounted into the sidewall of an automotive vehicle above a wheel well. The outside section of said combination illumination device would function as a combination amber running light and turn signal light, and the inside section of said combination illumination device would function as a switch controlled side marker light/turn signal light, or wheel well illumination white light for maintenance or repair of the wheel at night.

Said second or third embodiment of this instant invention can be mounted into the sidewall of a vehicle motor hood. Said hood is designed with a nearly vertical section of sidewall not visible to the motor vehicle operator. The outer side of said combination illumination device functions as a combination side marker/signal lamp and the inner side functions as a switch controlled engine area illuminator or night trouble light.

An U.S. DOT interpretation of Federal Motor Vehicle Standard 108 states that additional amber side marker lights that function as secondary directional signal lights on vehicles equipped with OEM red directional lamps, flash additional side marker directional lamps in a manner consistent with the OEM red lamps, and that is to extinguish the amber light in said side marker lamp and flash said lamp red/off, red/off. Motor vehicles with amber OEM directional lamps are required to flash said secondary directional lamps amber/off, amber/off. Said additional side marker lamps mounted on the rear quarter of a vehicle may extinguish their amber running light color and illuminate red with the red vehicle OEM brake lights. This instant invention will comply with said U.S.D.O.T-F.M.V.S 108 by utilizing newly designed electrical circuits not disclosed herein.
