The present teachings relate to a light system where two lights are separated by a space and an edge of one or both of the lights emit light into the gap so that the gap appears illuminated.
Vehicles include many different types of lights. Some types of lights included on a vehicle are low beam headlights, high beam headlights, tail lights, turn signal lights, fog lights, running lights, or a combination thereof. Each of these lights extend out of an outer surface of a vehicle so that they provide light for the driver or provide notice of surrounding drivers. These lights may have gaps of darkness where lights are not present such that the lights do not appear to be continuous.
Examples of light systems may be disclosed in U.S. Pat. Nos. 5,101,325; 6,305,813; 6,322,239; 6,508,563; 10,495,282 and U.S. Patent Application Publication Nos. 2013/0314935; 2014/0003075; and 2015/0369445 all of which are expressly incorporated herein by reference for all purposes. Thus, there is a need for a light system where the light system provides light across a gap so that the light appears to be continuous. There is a need for a system where light is projected outward from the light to fill an area that is free of light. It would be desirable to have an assembly that projects light from a pre-existing region that did not contain light.
The present teachings provide: a light system of a vehicle comprising: a housing comprising: a glue bucket; a glue leg located partially or entirely within the glue bucket; and a light guide located between the glue bucket and the glue leg; wherein the light system is located proximate to a gap in the vehicle and the light guide guides light from the light guide into the glue leg and from the glue leg across the gap so that the light extends across the gap to illuminate the gap.
The present teachings provide a light system where the light system provides light across a gap so that the light appears to be continuous. The present teachings provide a system where light is projected outward from the light to fill an area that is free of light. The present teachings provide an assembly that projects light from a pre-existing region that did not contain light.

The present teachings relate to a light system. The light system is located within a vehicle. Preferably, the light system is part of a vehicle such as a car, motorcycle, bus, truck, semi-truck, SUV, XUV, four-wheeler, dirt bike, tractor, combine, heavy equipment, farm equipment, industrial equipment, commercial equipment, or a combination thereof. The light system may project in a forward direction, rear direction, side direction, or a combination thereof. Preferably, the light system projects a light from an external surface of the vehicle to a location in front of the vehicle or at an angle relative to the front of a vehicle. The light system may direct some light at the ground. The light system may direct some light above the ground. The light system may be integrated into a front end, a rear end, or both of a car. The light system may project light out of the vehicle. The light systems may be multiple light systems stacked one above the other or integrated into a single light system. The light of the vehicle may be two or more, three or more, or four or more light systems located one above another. The light system may have a high beam and a low beam. A total height of the light systems may be decreased by placing all of the light sources in a single plane or on a same plane. The light system may include one or more light sources or a plurality of light sources.
The light sources function to produce light (e.g., one or more edge lighting sources). When more than one light source is present each of the light sources may perform different function, provide different light, perform a same function, provide a same light, or a combination thereof. The light source may be a device or a plurality of devices that create light and the light extends outward from the light source. The light source may produce a high beam, a low beam, a blending beam, a running light, a daytime light, a turn signal, a brake light, or a combination thereof. The light source may be aimed for near light, far light, blending light that blends the far light and near light together, or a combination thereof. The light sources may have different functions. For example, one light source may provide a running light and another light source may be a turn signal or fog light. The light source may comprise a plurality of lights or may be a single light source within a set of light sources. The plurality of lights may be in one set or group of light sources. The light source may be a single light that projects light. In another example, a single light source may direct light to a first location (e.g., a first light guide). The light source may be directional light. The light source may have an emission that is a Lambertian emission or a narrow emission angle. The directional light source may concentrate light on a light guide, towards a light bar, a reflector, or a combination thereof.

The light source may create a cone of light with an optical axis. The optical axis may be directed at a light guide, a lens, a light pipe, a reflector, away from a vehicle, or a combination thereof.
The light source may be any type of lighting device that produces light such as an incandescent bulb, fluorescent light, compact fluorescent lamp, halogen lamp, light emitting diode (LED), high intensity discharge lamps (HID); halogen lights, xenon lights, a laser diode, phosphorous bulb, or a combination thereof. The light source may be a single lamp or bulb. Preferably, the light source is part of a set of light sources that includes a plurality of lamps, bulbs, diodes, or a combination thereof. The light source may be part of a set of light sources that includes two or more, 3 or more, 4 or more, or 5 more light sources that produce light and combine together to form the light extending from the light system. The sets of light source may include 50 or less, 35 or less, 20 or less, or 15 or less devices that produce light (e.g., each set may include 5 light sources or alternatively all of the sets when combined together may include 5 light sources). For example, the set of light sources may be the contents of a single printed circuit board that perform a same lighting function and the set of light sources may be 5 light sources. The set of light sources may be all of the light sources on all of the printed circuit boards that create a same lighting function and may be 15 light sources. For example, there may be 30 total light sources, but only 15 perform a same function and those may be a set of light sources. The light source may be static. Preferably, a single light source will be directed at a single reflector, lens, light pipe, or a combination thereof. The light sources may be free of movement. The light source may be fixed or may be fixed relative to a reflector or a reflector housing.
