Reduced depth projector headlamp assembly
A reduced depth headlamp assembly for use in a motor vehicle. The housing includes an exterior lens, and a mirror, and defines a housing axis extending between the exterior lens and the mirror. The projector includes a light source, a reflector, and a condenser lens co-axially arranged along a projector axis defined between the light source and the condenser lens. The projector is mounted to the housing such that the projector axis and the housing axis form an angle, preferably a ninety (90) degree angle, thereby minimizing the depth of the assembly.
1. An automotive headlamp assembly for use in a motor vehicle, the motor vehicle defining vertical, cross-car and lengthwise axes, oriented perpendicular to one another, wherein the cross-car axis is oriented along a width of the vehicle and the lengthwise axis is oriented along a length of the vehicle, comprising:
a housing including an exterior cover lens and at least one mirror, the housing defining a housing axis extending between the exterior lens and the mirror and being oriented along the length wise axis of the vehicle;
a projector module including a halogen or HID light source, a reflector, and a condenser lens co-axially arranged along a projector axis defined between the light source and the condenser lens;
wherein the projector is coupled to the housing and a projector axis angle substantially greater than zero degrees is defined between the projector axis and the housing axis, whereby light from the light source is focused by the condenser lens onto the mirror, the mirror being configured to reflect the light through the exterior lens along the housing axis.
2. The automotive headlamp assembly of claim 1 , wherein the mirror is oriented with respect to the housing axis at a mirror angle.
3. The automotive headlamp assembly of claim 2 , wherein the mirror angle is one-half of the projector axis angle.
4. The automotive headlamp assembly of claim 2 , wherein the projector axis angle is 90 degrees and the mirror angle is 45 degrees.
5. The automotive headlamp assembly of claim 1 , wherein the projector is oriented about the housing axis with respect to the housing.
6. The automotive headlamp assembly of claim 5 , wherein the projector is oriented horizontally.
7. The automotive headlamp assembly of claim 5 , wherein the projector is oriented vertically.
8. The automotive headlamp assembly of claim 1 , wherein the mirror is integral with a frame of the housing.
9. The automotive headlamp assembly of claim 8 further comprising adjustment screws coupled to the housing and mirror, the adjustment screws being configured to move the mirror with respect to the housing.
10. The automotive headlamp assembly of claim 1 , wherein the mirror is movably mounted to the housing and includes a first adjustment mechanism configured to move the mirror with respect to the housing.
11. The automotive headlamp assembly of claim 10 wherein the first adjustment mechanism includes a screw.
12. The automotive headlamp assembly of claim 1 , wherein the projector is moveably coupled to the housing and includes a second adjustment mechanism configured to move the projector and projector axis with respect to the housing.
13. The automotive headlamp assembly of claim 12 , wherein the second adjustment mechanism includes a screw.
14. An automotive headlamp assembly for use in a motor vehicle, the motor vehicle defining vertical, cross-car and lengthwise axes, oriented perpendicular to one another, wherein the cross-car axis is oriented along a width of the vehicle and the lengthwise axis is oriented along a length of the vehicle, comprising:
a housing including an exterior cover lens and at least one mirror, the housing defining a housing axis extending between the exterior lens and the mirror and being oriented along the length wise axis of the vehicle;
a projector module including a light source, a reflector, and a condenser lens co-axially arranged along a projector axis defined between the light source and the condenser lens;
wherein the projector is coupled to the housing and a projector axis angle substantially greater than zero degrees is defined between the projector axis and the housing axis, whereby light from the light source is focused by the condenser lens onto the mirror, the mirror being configured to reflect the light through the exterior lens along the housing axis, the headlamp assembly being pivotably mounted within the vehicle and an actuator being coupled to the housing and configured to pivot the housing between an “on” and an “off” position.
15. An automotive headlamp assembly for use in a motor vehicle, the motor vehicle defining vertical, cross-car and lengthwise axes, oriented perpendicular to one another, wherein the cross-car axis is oriented along a width of the vehicle and the lengthwise axis is oriented along a length of the vehicle, comprising:
a housing including an exterior cover lens and at least one mirror, the housing defining a housing axis extending between the exterior lens and the mirror and being pivotably mounted and oriented along the lengthwise axis of the vehicle;
a projector module including a light source, a reflector, and a condenser lens co-axially arranged along a projector axis defined between the light source and the condenser lens and being stationarily mounted to the vehicle;
wherein the projector is pivotably coupled to the housing and a projector axis angle substantially greater than zero degrees is defined between the projector axis and the housing axis, whereby light from the light source is focused by the condenser lens onto the mirror, the mirror being configured to reflect the light through the exterior lens along the housing axis, and an actuator being coupled to the housing is configured to pivot the housing relative to the projector between an “on” and an “off” position.
