Title: Narrow aperture light system

Description:
FIELD 
     The present teachings relate to a light system including lights are directed through lenses so that a field illuminated remains the same while an aperture out of a vehicle is reduced. 
     BACKGROUND 
     Headlights in vehicles typically are static in position and once aimed maintain the aim. In order to illuminate a larger area the headlights are switched from a low beam to a high beam. In order to illuminate a predetermined field size the light extends out of the vehicle at a predetermined angle through a predetermined aperture size. Typically, the larger the aperture size the larger the area illuminated by the headlights. 
     Examples of light systems may be disclosed in U.S. Pat. Nos. 6,382,822; 7,121,705; and 7,690,826 and PCT Publication No. WO2015/191387 all of which are expressly incorporated herein by reference for all purposes. Thus, there is a need for a light system where the light source is located horizontally off a center axis, vertically off of a center axis, or both. There is a need for a system with a reduced aperture size due to an orientation of a lens, an outer lens, or both within the light system. It would be desirable to have a light system where the lights extend through two or more lenses. 
     SUMMARY 
     The present teachings provide: a light system comprising: (a) one or more reflectors; (b) a lens; (c) an optical axis extending through the one or more reflectors, the lens, or both; and (d) a light source located entirely on one side of the optical axis so that light from the light source is directed at an angle relative to the one or more reflectors and the one or more reflectors redirect the light through the lens.

     DETAILED DESCRIPTION 
     The explanations and illustrations presented herein are intended to acquaint others skilled in the art with the invention, its principles, and its practical application. Those skilled in the art may adapt and apply the invention in its numerous forms, as may be best suited to the requirements of a particular use. Accordingly, the specific embodiments of the present invention as set forth are not intended as being exhaustive or limiting of the teachings. The scope of the teachings should, therefore, be determined not with reference to the above description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. Other combinations are also possible as will be gleaned from the following claims, which are also hereby incorporated by reference into this written description. 
     The present teachings relate to a light system. The light system is located with 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. 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. The light of the vehicle may be two or more, three or more, or four or more light systems located one above another. A height of each of the light systems may be decreased by the light source being moved to a side of the reflector (e.g., versus above or below the reflector). The light system may include one or more light assemblies and preferably a plurality of light assemblies. 
     The light sources function to produce light. 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, 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 source may comprise a plurality of lights. For example, the light source may have a first light that is directed to the first reflector facet, a second light that is directed to the second reflector facet, a third light that is directed to the third reflector facet, and fourth light that is directed to the fourth reflector facet. The plurality of lights may be in one group and may direct light to the reflector facets. The light source may be a single light that projects light. In another example, a single light source may direct light to the first reflector facet, the second reflector facet, the third reflector facet, and the fourth reflector facet. 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 the reflector. The light source may include a laser diode, glowing phosphor, filament bulb, or a combination thereof. The light source may create light may extend at an angle of about 15 degrees or more, about 30 degrees or more, about 45 degrees or more, or about 60 degrees or more from an optical axis of the light source into contact with the one or more reflectors (e.g., when viewing a two dimensional representation of the light from the light source, the light includes a first edge at a first angle and a second edge at the first angle from the optical axis). The light source may create light that may extend at an angle of about 150 degrees or less, about 135 degrees or less, about 115 degrees or less, about 105 degrees or less, or about 90 degrees or less from an optical axis of the light source into contact with the one or more reflectors (i.e., about 60 degrees on each side of the optical axis). For example, the light source may produce light having a cone that extends at 60 degrees on each side of the optical axis and the edges of the light may form an angle of about 45 degrees on one side and about 90 degrees on a second side with the one or more reflectors. The angle of the light from the light source may form different angles with the reflector due to a shape of the reflector (e.g., parabolic shaped). 
     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 includes a plurality of lamps, bulbs, diodes, or a combination thereof. The light source may be an array. The light source may include two or more, 5 or more, 10 or more, 20 or more, or even 50 or more devices that produce light and combine together to form the light source. The light source may include 500 or less, 300 or less, or 200 or less devices that produce light. For example, if the light source is a 10×10 array of light devices some of the  100  devices may be selectively turned on and off, dimmed, brightened, or a combination thereof. Preferably, the light sources may be a single light source that is aimed at a focus of a single reflector. The light source may be static. The light source may be free of movement. The light source may be fixed. The light sources may be static and may be manually or physically adjusted so that the light sources are directed to a desired location. The light source may be fixed and the light from the light source may be moved, bent, directed, or a combination thereof by optical elements or reflectors. Each device of the light source may be turned on an off. The light source may be located within a light system at a location relative to a reflector. The light source may be located entirely on one side of an optical axis extending through the lens. The light source may be located entirely outside an outer edge of a reflector. The light source may be located farther from an optical axis, a longitudinal axis, or both than a first outer edge of a reflector. The light source may be located outside of all of the indirect light reflecting off of the reflector. The light source may be located farther from an optical axis extending through the reflector than both outside edges of the reflector (e.g., first outside edge and second outside edge). The light source may be coplanar with a region of the one or more reflectors, the lens, or both. The light source may be coplanar with a center of the one or more reflectors, the lens, or both. The light source may be located on a horizontal axis that bisects the one or more reflectors, the lens, or both. The light source may direct light above a driving surface (e.g., some light may contact and illuminate the driving surface by a center of the light may be located above the driving surface). The light source may be directed substantially parallel to the light surface (e.g., ground). For example, a center of the light, an axis of the light, or both may extend parallel to the driving surface. The light source may be directed directly out of the vehicle. The light source may be directed along a vertical axis and some light may extend outward along a horizontal axis. The light source may extend along an optical axis or may be directed away from the optical axis. 
     The optical axis is an axis of light extending away from a vehicle, a light system, or both. The optical axis may be a center of light extending away from a vehicle. The optical axis may be a center of a cone of light. The optical axis may extend through a center of a lens, a center of a curvature of a lens, a center of a reflector, or both. The optical axis may bisect the lens (e.g., primary lens), the reflector, or both. The optical axis may extend towards the reflector, through the lens, or both. Preferably, the optical axis contacts the reflector in a first direction and then extends through a lens in a second direction. The optical axis may extend substantially parallel to a vertical axis or a longitudinal axis. The longitudinal axis may bisect a length of a vehicle. The vehicle may have an optical axis on a first side (e.g., a left-handed light) of the longitudinal axis and a second optical axis on a second side (e.g., a right-handed light) of the longitudinal axis. The vertical axis, longitudinal axis, and the vertical axis all extend parallel or substantially parallel to one another. A horizontal axis may extend substantially parallel to the optical axis, vertical axis, longitudinal axis, or a combination thereof. The horizontal axis may extend along a width of a vehicle. The horizontal axis may be located on a first side and a second side of the longitudinal axis, vertical axis, optical axis, or a combination thereof. 
     Each of the light systems, light sources, or both may direct light on a first side and a second side of an optical axis. Some of the light may extend on an inboard side of the optical axis (e.g., in a direction towards a center of a vehicle). Some of the light may extend on an outboard side of the optical axis (e.g., in a direction away from a center of a vehicle). The light may extend farther on an outboard side than an inboard side of a light. The light on the inboard side may illuminate a region between two light sources and in front of a vehicle. A right-handed light and a left-handed light may each include light that extends inboard (e.g., on an inboard side) so that the inboard lights overlap and illuminate in front of a vehicle. A right-handed light and a left-handed light may each include light that extends outboard (e.g., on an outboard side) of a vehicle so that the outboard light illuminates a region outside of the vehicle, sides of a road, or both. The light from each of the light sources may extend outward from the light source at an angle towards an inboard side and an outboard side. The light extending on the inboard side may extend outward from the light source, vehicle, or both at an angle of about 10 degrees or more, about 20 degrees or more, about 25 degrees or more, or about 30 degrees or more relative to the optical axis. The light extending on the inboard side may extend outward from the light source, the vehicle, or about at an angle of about 50 degrees or less, about 40 degrees or less, or about 35 degrees or less relative to the optical axis. The light extending on the outboard side may extend outward from the light source, vehicle, or both at an angle of about 20 degrees or more, about 30 degrees or more, about 35 degrees or more, or about 40 degrees or more relative to the optical axis. The light extending on the outboard side may extend outward from the light source, the vehicle, or about at an angle of about 60 degrees or less, about 50 degrees or less, or about 45 degrees or less relative to an optical axis. An angle the light extends on an inboard side and an outboard side of the optical axis may be varied based on a shape of a reflector. 
     The reflector functions to direct light to a predetermined location, in a predetermined direction, or both. The reflectors may direct light from the light sources so that near light, far light, blended light, or a combination thereof are directed outward from the light system. The reflector may redirect light at an angle of about 20 degrees or more, about 25 degrees or more, about 30 degrees or more, about 35 degrees or more, about 40 degrees or more, or about 45 degrees or more. The reflector may redirect light at an angle of about 135 degrees or less, about 115 degrees or less, about 105 degrees or less, about 90 degrees or less, or about 75 degrees or less. The reflector functions to extend light through a first lens (e.g., a primary lens within a light system), a second lens (e.g., an outer lens), or both. The lens (i.e., primary lens) may be located between an outermost lens and the one or more reflectors. The reflector and lens may be located a distance from one another. The reflector may be located a first distance from the lens on a first side and a second distance from the lens on a second side. The first distance may be greater than the second distance. A first outside edge of the reflector may be located a greatest distance from the lens and a second outside edge of the reflector may be located closest to the lens. Each of the facets of the reflector may be located a distance from the lens. Starting at a first outside edge and extending towards the second outside edge, each facet may be located closer to the lens. The distance between the reflector and the lens may vary based upon a curve of the reflector, shape of the lens, or both. The distance between the lens and the reflector at a first outside edge, a second outside edge, or both may be about 1 mm or more, about 3 mm or more, about 5 mm or more, about 7 mm or more, about 1 cm or more, about 1.5 cm or more, about 2 cm or more, or about 5 cm or more. The distance between the lens and the reflector at a first outside edge, a second outside edge, or both may be about 10 cm or less, about 7 cm or less, about 5 cm or less, or about 3 cm or less. The reflector may have a ratio of distances between the first outside edge and the second outside edge. The ratio of the distance at the first outside edge to the second outside edge may be about 1.2:1 or more, about 1.5:1 or more, about 2:1 or more, about 2.5:1 or more, about 3:1 or more, about 3.5:1 or more, or about 4:1 or more. The ratio of the distance at the first outside edge to the second outside edge may be about 10:1 or less, about 7:1 or less, or about 5:1 or less. The distance between the reflector and the lens may determine the spread of light, the contact angle between the lens and the indirect light, or both. 
     The reflector functions to aim light, redirect light, spread light, or a combination thereof. The reflector may intensify light from the light sources. Light that contacts the reflector may be spread and redirected (e.g., light may not be only a beam of light the light may be spread). The reflector may form a predetermined light pattern. The reflector, the light source, PCB, or a combination thereof may all be aligned relative to each other so that a light pattern is created. The reflector may include an outer edge. The outer edge of the reflector and the light source may be located proximate to one another. Preferably, the light source may be located farther from an optical axis than an outer edge of the reflector. The light source may be located outside of the reflector so that a line extending from an outer edge of the reflector to the lens does not pass through the light source. The light pattern may be determined based upon the shape of the reflector. The reflector may have a shape that is generally parabolic. For example, the reflector may have a curvature that is substantially symmetric in a vertical direction, a horizontal direction, or both. The reflector may be asymmetric (e.g., one side may be longer than another side or more curve more than an opposing side. The reflector may be “C” shaped, “U” shaped, “J” shaped, “L” shaped, be convex, be concave, or a combination thereof. The reflector may receive light directly from the light source and then reflect the light in another direction. The reflector may have a shape disclosed herein when all of the facets, sub-facets, or both are viewed together. The reflector may have one or more facts, one or more sub-facets, or both. Preferably, the reflector has a plurality facets and each of the plurality of facets include sub-facets and each of the sub-facets direct light through the lens, generally along an optical axis, and to a region outside of a vehicle. The reflector may have a surface area that is greater than a surface area of the lens. The surface area of the reflector may be about 1.1 times or more, about 1.2 times or more, about 1.3 times or more, about 1.5 times or more, or even about 1.7 times or more than that of the lens. The surface area of the reflector may be about 3 times or less, about 2.5 times or less, or about 2 times or less than that of the lens. Multiple reflectors may be combined together to create a predetermined light pattern. The reflector and the lens each include a height and a length. The height of the reflector may be greater than a height of the lens. The height of the reflector may be about 1.1 times or more, about 1.2 times or more, or about 1.3 times or more that of a height of the lens. The height of the reflector may be about 3 times or less, about 2 times or less, or about 1.5 times or less that of a height of the lens. The reflector may have one or more facets. The reflector may have a plurality of facets. Each of the plurality of facets may direct or reflect light to a different location. The facets may create an array of light. The array of light may cover an area with a spectrum or range of light. The reflector may have a first reflector facet, a second reflector facet, a third reflector facet, etc. . . . . The reflector may have a plurality of reflector facets. 
     The reflector facets may function to redirect light to a predetermined location. Some or all of the reflector facets function to create a shape or indication of direction of the reflected light. One or more of the reflector facets may curve in a vertical direction. The one or more reflector facets may curve so that a vertical surface of the reflector has a generally curved shape. The one or more reflector facets may curve in a horizontal direction. Each of the reflector facets may be individually curved in the horizontal direction or when combined together may create one continuous curve. The plurality of facets in the horizontal direction may be stepped (e.g., a first surface may extend above a second surface of an adjacent facet or vice versa). The reflector may create steps in the single reflector by the plurality of facets. The one or more reflectors may be a plurality of reflectors that are located one another. The one or more reflectors may be a plurality of reflectors located one another. The one or more reflectors may be a plurality of reflectors forming facets that are located adjacent one another. The reflector facets, sub-facets, or both may direct light onto the ground, above the ground, or both. The reflector facets, sub-facets, or both may reflect light from a light source outward from a vehicle. The reflector facets, sub-facets, or both may direct light to a predetermined location. Each reflector may be a single reflector. The one or more reflectors may be a single reflector. The reflector may be a dingle reflector with a plurality of reflector facets, plurality of sub-facets, or both. The reflector may direct substantially all of the light through a single lens (e.g., except for light that is blocked by a shield). Each light assembly may include one reflector or a plurality of reflectors. The reflector facets may be a first reflector facet, a second reflector facet, a primary reflector facet, a blended reflector facet, or a combination thereof. The first reflector facet and the second reflector facet may direct light generally to a same location. The first reflector facet may direct light in a first direction. The second reflector facet may direct light in a second direction. The first reflector facet and the second reflector facets may create one or more light patterns. The first direction and the second direction may cross so that the one or more light patterns may be formed or a single light pattern may be formed by the first reflector facet and the second reflector facet. The first reflector facet and the second reflector facet may be located within a same plane. Preferably, the first reflector facet and the second reflector facet extend out of a primary plane as the primary reflector facet, out of a blended plane as the blended reflector facet, or both. The first reflector facet and the second reflector facet may be aimed generally towards each other. The reflector may include two or more, four or more, six or more, or eight or more facets. The reflector may include 20 or less, 15 or less, or 10 or less facets. The each of the reflector facets or totality of the reflector facet may have a generally parabolic shape, may form a concave region therebetween, may have curvature, or a combination thereof. The shape of the facet may determine a type of light reflected. 
     The facets may reflect light so that the light is blended light, foreground light, spread light, intermediate light, cutoff light, a hotspot, or a combination thereof. The foreground light may illuminate a large region in a direction of motion. The foreground light may be a primary light source that an operator views while a vehicle is moving. The foreground light and spread light may have a substantial overlap (e.g., 50 percent or more, 60 percent or more, 75 percent, or more, or 90 percent or less). The spread light may have a length that is greater than a length of the foreground light so that a region outside of a width of the vehicle may be illuminated. The intermediate light may be a blend light that blends the foreground light and spread light. The intermediate light may illuminate a region wider than the spread light (e.g., wider than the vehicle and the spread light). The intermediate light may illuminate a region generally in a direction of movement of the vehicle. The intermediate light may be at least partially overlapped by a cutoff light. The cutoff light may create a hot spot. The cutoff light may illuminate a distal region in front of a vehicle. The cutoff may illuminate a region proximate to the vehicle. The reflector facets may be angled inwards towards a center line or optical axis that extends along the reflector. The reflector facets may each include sub-facets. The sub-facets and facets may work in conjunction to reflect the light to create light that is blended light, foreground light, spread light, intermediate light, cutoff light, a hotspot, or a combination thereof. The foreground light may illuminate a large region in a direction of motion. 
     The sub-facets may function to change a shape of a reflector or a facet. Each reflector facet may include sub-facets. The sub-facets may each be a change in shape along a facet. The sub-facets may each be flat, curved, concave, convex, symmetrical, asymmetrical, or a combination thereof. Each facet may include two or more or three or more sub-facets. Each facet may include 10 or less, 8 or less, 6 or less, or about 4 or less sub-facets. The sub-facets may be angled relative to each other. The sub-facets may extend at an angle of about 5 degrees or more, about 10 degrees or more, about 15 degrees or more, about 20 degrees or more, or about 25 degrees or more relative to each other. The sub-facets may extend at an angle of about 45 degrees or less, or about 40 degrees or less, about 35 degrees or less, or about 30 degrees or less relative to each other. The sub-facets may have a curved shape. The curved shape may be arcuate. Each of the sub-facets may have a line that is tangential to point on the sub-facet. Thus, for example, a tangent line along an upper sub-facet may have an angle relative to a tangent line along a middle sub-facet. The sub-facets may have an angle relative to vertical (e.g., direction of gravity). For example, a facet may include three sub-facets, a center of the three sub-facets may extend substantially parallel to the lens and then a sub-facet located above and below the center sub-facet extend at an angle of about 10 degrees relative the center sub-facet. The sub-facets may be an upper sub-facet, middle sub-facets, lower sub-facets, or a combination thereof. The upper sub-facets may be located above the middle sub-facets and the lower sub-facets. The upper-sub facets may be angled downward relative to an optical axis the middle sub-facet, the lower sub-facet, vertical, or a combination thereof. The sub-facets may angle a cone of light (e.g., reflected light) away from each of the sub-facets. The parabolic shape of the reflector may have one side that is closer to a lens and one side that is farther from a lens. 
     The one or more lenses function to direct the light from the reflectors to a location to be illuminated. The lenses may bend light. The lenses may refract light. The lenses may diffuse the light, blend the light, spread the light, direct the light to a predetermined location, create one or more hot spots, or a combination thereof. The lens may be located in front of the reflectors, the light sources, or both. The one or more lenses may be located inside of an external lens. The lenses may cover all or a portion of the light system, the light source, the reflectors, or a combination thereof. Each light system may include a lens. Thus, if there are three light systems or light sources then each light system or light source may include a lens. For example, the light system may include three lights and each of the three lights may include a lens. In another example, a light system may include a kink light, spread light, and high beam light and each may include a lens. The lens may cover the reflectors so that light, direct light, reflected light, or a combination thereof extends through the lens. The lens may be one or more lenses. The lens may be a plurality of lenses. The lens (e.g., primary lens or internal lens) may be a single lens. The one or more lenses may have a shape that directs light to a predetermined location. The one or more lenses may be flat, planar, bio-convex, plano-convex, positive meniscus, negative meniscus, plano-concave, bio-concave, double convex, converging, diverging, or a combination thereof. Each lens may be a single lens. Each lens may be a compound lens (e.g., there may be more than one lens). Each lens has a forward side and a rearward side. 
     The forward side, the rearward side, or both function to reflect the light, refract the light, spread the light, aim the light to a predetermined location, or a combination thereof. The forward side and the rearward side may be parallel to each other. The forward side and the rearward side may have an angle relative to one another. For example, a forward surface may be planar and the rearward surface may be curved or angled. Conversely, the rearward surface may be planar and the forward surface may be curved. The shape of the forward surface, the rearward surface, or both may have a shape. The shape of the forward surface, the rearward surface, or both may be selected to determine where light is directed. The forward surface, the rearward surface, of both may cause light to diverge, converge, spread, create a hot spot, blend the light, or a combination thereof. The forward side, the rearward side, or both may be concave, convex, spherical, or a combination thereof to produce a shape such as bioconcave, bioconvex, plano-concave, plano-convex, meniscus, or a combination thereof. The forward side may be located proximate to a lens (e.g., an outer lens) of the light system. 
     The outer lens may function to protect the light system, house all of the internal components, or both. The lens (e.g., outer lens) may be an outer most part of a light system. The lens may receive all of the light from the lens to be directed outward from the vehicle, in a direction of movement of a vehicle or, both. The lens may be sufficiently strong to protect the light system from rocks and debris as the vehicle moves. The lens may cover all of the light sources of the light system (e.g., a kink light, spread light, high beam light). The lens may be transparent so that light may extend through the outer lens. The outer lens may cover all of the lights (e.g., kink light, spread light, high beam light). 
     The light functions to illuminate a region of direction of a vehicle. The light may illuminate a forward region, a side region, or both of a vehicle. The kink light may asymmetrically aim the light. The link light may include a bend. The kink light may bend the light upward, downward, bend the light, create a cutoff portion of the light, or a combination thereof. The link and spread light may blend together. The spread light may extend light outward from the optical axis, outward from the optical axis relative to the kink light, or both. The spread light may act to blend the lights together so that there are not dark spots or hot spots. The spread light, kink light, or both may operate while a high beam light is in operation. The high beam light may increase an intensity of light so that a larger region is illuminated, a farther distance in a direction of movement is illuminated, or both. The high beam light, kink light, spread light, or a combination thereof may all include direct light and indirect light. 
     The direct light functions to extend light from a light source to a reflector. The direct light may be directed away from a region to be illuminated. Direct light may extend in a first direction and reflected light may extend in a second opposite direction. The direct light may be aimed at a reflector. The direct light may be a first direct light, a second direct light, a primary direct light, a blended direct light, or a combination thereof. The direct light may be characterized based upon a location the direct light contacts the reflector. The direct light may contact one or more of the reflector facets. Preferably, the direct light contacts all of the facets of a reflector. More preferably, the direct light illuminates entirely all of the reflector. The direct light is directed from a light source to a reflector. The direct light may have a first edge and a second edge that are both located within a first edge and second edge of the reflector (e.g., within outside edges of the reflector). The directly light may span a region. Preferably, all of the direct light contacts the reflector. All of the direct light may span a region and the region may contact reflector. Direct light may be contact a shield so that any light not directed to the reflector may be blocked. The direct light may contact the reflector and then be reflected light that extends from the reflector towards a predetermined location or an aimed location. 
     The reflected light functions to form a light pattern, illuminate a region around a vehicle, illuminate in a direction of movement, extend through one or more lenses, or a combination thereof. The reflected light may illuminate a surface, an object, a location of interest, or a combination thereof. The reflected light may be a first reflected light and a second reflected light. The reflected light may span a region in a direction of movement of a vehicle. The reflected light may be the light that illuminates so that objects, vehicles, animals, people, or a combination there may be avoided. The reflected light may extend along an optical axis. The reflected light may be form the configuration discussed herein regarding extending on an inboard side and outboard side of the optical axis. Thus, for example, the reflected may extend in an outboard direction at an angle of about 43 degrees from the optical axis and in the inboard direction at an angle of about 30 degrees relative to the optical axis. The shape of the reflected light may be controlled or changed via one or more shields. 
     The one or more shields function to prevent stray light from being transmitted. The shield may block some light from the light source to the reflector or a region around the reflector, to the lens by bypassing the reflector, or both. The one or more shields may be made of an opaque material, a material that absorbs light, a material that blocks light, a material that is free of reflecting light, or a combination thereof. The one or more shields may be planar, straight, curved, bend, have an “L” shape, have an “M” shape, extend along a first side of a light source, extend along both a first side and a second side of a light source, or a combination thereof. The one or more shields may assist in controlling a shape of the light, an isocandela shape of the light, or both. 
       FIG. 1  illustrates a top view of a vehicle  2  including a light system  10 . The light system  10  includes light sources, reflectors  14 , and lenses  16 ,  18 . The vehicle  2  and light  30  are projected in the direction  20  in front of the vehicle  2 . The light  30  is created by the light source  12  and directed to the reflector  14 . From the reflector  14  the light  30  extends through a first lens  16  and an outer lens  18  to illuminate a region outside of the vehicle  2 . 
       FIG. 2  illustrates a light system  10  with a light source  12  located along a side of the reflector  14  and lens  16 . The reflector  14  has a plurality of facets  22  so that the reflector is curved in both the vertical direction and the horizontal direction. The facets  22  redirect the light  30  (direct light  40 ) from the light source  12  through the lens  16  (indirect light  42 ). As shown, the facets  22  in vertical direction are labeled. 
       FIG. 3  is a top view of a light system  10 . The light system  10  includes a light source  12 , a reflector  14  with a plurality of horizontal facets  22 , and a lens  16 . The light source  12  creates light  30 , which is projected to the facets  22  of the reflector  14 . A shield  90  is located proximate to the light source  12  and prevents light from extending from the light source  12 , reflectors  14 , or both in a direction outside of the lens  16 . The facets  22  are located a distance (H 1  through H X ) from the lens  16  and the facets  22  redirect the light  30  through the lens  16 . The reflector  16  includes an outside edge  24  and the light source  12  is located outside of the outside edge  24 . 
       FIG. 4  is a front view of the light system  10 . The light system  10  includes a reflector  14  having a height (H R ) and a lens  16  having a height (H L1 ). The height of the lens  16  is less than the height of the reflector  14 . The light created by the light source  12  is reflected off of the reflector  14  and through the lens  16  so that a predetermined area is illuminated. The shape of the reflector  14  is such that the light is directed through a lens  16  with a smaller area than the reflector  14 . The light source  12  is located on horizontal axis  72 . 
       FIG. 5  illustrates a light system  10  including three different lights that illuminate a region around a vehicle (not shown). The light system  10  includes a kink  32 , a spread  34 , and a high beam  36  each of which provide different light at different intensities around a vehicle. Each of the kink  32 , spread  34 , and high beam  36  include reflectors  14  having a plurality of reflector facets  44  and sub-facets  46  along each of the reflector facets  44  that redirect the light in a predetermined direction. 
       FIG. 6  is a top view of the light system  10  depicting the angles or reflection of the light  30  and the angle of the reflector  14  relative to the lens  16 . The light source  12  creates light  30 , which is directed towards the reflector  14  along an optical axis  74 , which is also a vertical axis  70 . The light source  12  is located entirely on one side of a vertical axis  70  and as shown is located to the side of the reflector  14  and the lens  16 . The light  30  has a directed light with a first side  52 ′ and a second side  52 ″ that are separated by an angle (a). The directed light  52 ′ and  52 ″ contacts the reflector  16  and then is redirected through the lens  16 . The directed light on the first side  52 ′ is redirected by the reflector  16  and becomes redirected light  54 ′ that extends at an angle (13) relative to the directed light  52 ′. The first side  52 ′ and second side  52 ″ illustrate sides of the direct light  40 , and the first side  54 ′ and the second side  54 ″ illustrate sides of the indirect light  42  extending through the lens  16  The directed light on the second side  52 ″ is redirected by the reflector  16  and becomes redirected light  54 ″ that extends at an angle (y) relative to the directed light  52 ″. 
       FIG. 7  is an isocandela  50  showing the light source  12  of a vehicle from the right side light of the vehicle  2  (i.e., a right-handed light). The light from the light source  12  extends towards an inboard side  4  a distance (D I ) and towards an outboard side  6  a distance (D O ) from a longitudinal axis  76  of the vehicle  2 . A left-handed light creates an isocandela that is a reverse mirror image of the isocandela shown. 
       FIG. 8  illustrates a light system  10  with a light source  12  located along a side of the reflector  14  and lens  16 . The reflector  14  has a plurality of facets so that the reflector is curved in both the vertical direction and the horizontal direction. The facets receive direct light  40  from the light source  12  and reflect indirect light  42  through the lens  16 . The light  30  from the lens  16  changes direction as the light  30  enters a rearward side  17 ″ of the lens  16  and exits the forward side  17 ′. 
       FIG. 9A  illustrates a light source  12 , reflector  14 , and lens  16 . The lens  16  is longer than the reflector  14  and has a height greater than the reflector  14 . The light source  12  is located off to one side of the reflector  14 . The light source  12  directs light onto the reflector  14  and the reflector  14  redirects the light through different regions of the lens  16  and each of the regions spread the light in a different manner depending upon the shape and orientation of the facets and sub-facets as is discussed herein. The reflector  14  reflects a foreground light  100 , a spread light  102 , an intermediate light  104 , and a cut off light  106 , the pattern of which is visible in  FIG. 9B . 
       FIG. 9B  illustrates that pattern of reflected light extending through the lens (not shown). The foreground light  100  creates a rectangular pattern through the lens to illuminate a large region. The spread light  102  also creates a rectangular pattern but provides light outside of the foreground light  100 . The intermediate light  104  illuminates a region between and overlapping a portion of the foreground light  100  and spread light  102 . The cutoff light  106  creates a partial hotspot in front of a vehicle so that a region in a direction of movement is illuminated.

       FIG. 10B  illustrates that pattern of reflected light extending through the lens (not shown). The foreground light  100  creates a rectangular pattern through the lens to illuminate a large region. The spread light  102  also creates a rectangular pattern but provides light outside of the foreground light  100  (e.g., has a greater length). The intermediate light  104  illuminates a region between and overlapping a portion of the foreground light  100  and spread light  102  and provides light to a region outside of a width of a vehicle (not shown), the foreground light  100 , and the spread light  102 . The cutoff light  106  creates a partial hotspot in front of a vehicle so that a region in a direction of movement is illuminated. 
     Any numerical values recited herein include all values from the lower value to the upper value in increments of one unit provided that there is a separation of at least 2 units between any lower value and any higher value. As an example, if it is stated that the amount of a component or a value of a process variable such as, for example, temperature, pressure, time and the like is, for example, from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, it is intended that values such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 etc. are expressly enumerated in this specification. For values which are less than one, one unit is considered to be 0.0001, 0.001, 0.01 or 0.1 as appropriate. These are only examples of what is specifically intended and all possible combinations of numerical values between the lowest value and the highest value enumerated are to be considered to be expressly stated in this application in a similar manner. 
     Unless otherwise stated, all ranges include both endpoints and all numbers between the endpoints. The use of “about” or “approximately” in connection with a range applies to both ends of the range. Thus, “about 20 to 30” is intended to cover “about 20 to about 30”, inclusive of at least the specified endpoints.
