DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the Figures, wherein like numerals indicate like or corresponding parts throughout the several views, an exterior rearview mirror assembly for use with an automotive vehicle is generally shown at 10 in Figures 1 and 2. Referring specifically to Figure 1, the mirror assembly 10 includes a support base 12 having a first end 14 and an opposite distal second end 16. The first end 14 is adapted to be fixedly secured to the side of a vehicle, such as an exterior A-pillar or door panel as depicted at 18. The support base 12 extends outwardly from the door panel 18 along a generally horizontal plane from the first end 14 to the second end 16. The mirror assembly 10 further includes a mirror housing 20 operatively coupled to the support base 12. More specifically, the mirror housing 20 includes a hollow shell portion 22 having a front opening 24 and an extension axm portion 26 extending from the shell portion 22 and coupled to the support base 12. The arm portion 26 is coupled to the support base 12 by a power and/or manual pivot mechanism 28, as is conventionally known in the art and to one skilled in the art. The pivot mechanism 28 pivots the mirror housing 20 about the support base 12 between an extended use position, as shown in Figure 1, and a folded, or stowed, position as shown in Figure 2.
The mirror assembly 10 also includes a mirror pane 30 operatively coupled to the mirror housing 20 by a swivel member 32. The mirror pane 30 is a reflex glass pane for providing a reflective view to the occupant of the vehicle. The swivel member 32 pivotally connects the mirror pane 30 to the mirror housing 20 for providing articulating, or pivotal, movement of the mirror pane 30 with respect to the mirror housing 20 in order to adjust the angular view through the mirror pane 30 from the vehicle as is commonly known to one skilled in the art. The mirror assembly 10 additionally includes at least one light source 34 mounted to the support base 12 for illuminating at least one source of light from the mirror assembly 10. It should be appreciated that the light source 34 may also be mounted to the mirror housing 20 without varying from the scope of the invention.
Referring to Figure 3, the distal second end 16 of the support base 12 and the light source 34 is shown. The second end 16 of the support base 12 includes an inner wall 36, a rear wall 38 projecting outwardly from the inner wall 36, and an upper wall 40 interconnecting the inner wall 3 6 and the rear wall 3 8. The inner wall 3 6, rear wall 3 8, and upper wall 40 form a partial funnel-like structure on the second end of the support base 12. A
hollow and transparent lens 42 is removably secured to the second end 16 of the support base 12 and covers the inner wall 36, rear wall 38 and upper wall 40. The lens 42 may be clear plastic, colored or include fresnel lenses imbedded therein for shaping light from the light source 34. The light source 34 further includes a plurality of light filaments 44, 46, 48. A
first light filament 44 is fixedly secured to the inner wall 36, a second light filament 46 is secured to the rear wall 38 and a third light filament 48 is secured to the upper wall 40. The light filament may be an LED, as shown in Figure 3, or may include a bulb filament, or other known light-producing source. The light filaments 44, 46, 48 project an array of light in a discrete direction from the end of the support base 12. More specifically, the light filament 44 projects an array of light outwardly from the mirror assembly 10 and generally perpendicular from the side of the vehicle. The light filament 46 projects an array of light rearward toward the back or rear of the vehicle. Finally, the light filament 48 projects an array of light downwardly toward the ground adjacent the side of the vehicle.
Referring again to Figure 1, the mirror assembly 10 further includes an actuator 50 operatively connected to the light source 34 for actuating and illuminating the light source 34 to project the array of light in one of a plurality of discrete directions.
More specifically, the actuator 50 is electrically connected to each of the light filaments 44, 46, 48 for actuating and illuminating each of the light filaments 44, 46, 48. When activated, the light filament 44, 46, or 48 projects an array of light in the respective discrete direction as described above. The actuator 50 of the preferred embodiment is a series of electrical circuits connected to each of the light filaments 44, 46, 48 for sending an electrical current to the light filament 44, 46, or 48 to actuate and illuminate the filament 44, 46, 48.
The mirror assembly 10 also includes a controller, shown schematically at 52 in Figure l, for controlling the actuator 50 and illuminating the light source 34 to~project the array of light in a selective one of the plurality of discrete directions.
That is, the controller 52 sends a signal to the actuator 50 to selectively actuate one of the light filaments 44, 46, or 48 to project the array of light iwthe respective discrete direction from the light filament 44, 46, or 48. The controller 52 receives input signals 54 from various components 56 of the vehicle and transmits an output signal 58 to the actuator 50 to selectively actuate and illuminate one of the light filaments 44, 46, or 48. More specifically, the components 56 of the vehicle transmitting input signals 54 to the controller 52 may include one or more of the following: a vehicle "key fob" for locking and unlocking the doors of the vehicle, a sensor for indicating the open and closed state of the vehicle doors, a vehicle transmission, a vehicle transmission selector, and/or an ignition sensor.
Referring to Figure 4, a control table 60 is shown illustrating the operation of the mirror assembly 10. In operation, when the vehicle operator is approaching the vehicle, the mirror housing 20 is in the folded position and the mirror pane 30 remains parked in its previously operator adjusted position, or "normal" position. If the operator activates the keyfob component 56 to unlock the doors of the vehicle, the controller 52 sends a signal to the actuator 50 and activates the light source 34, or assist light, to an "ON"
condition. More specifically, the light filament 44 is turned on and illuminated to direct light from the mirror assembly 10 to assist the operator in locating the vehicle. It should be appreciated that the controller 52 and actuator 50 may activate each of the light filaments 44, 46, and 48 to project additional light from the mirror assembly 10 if desired. After the keyfob component 56 is activated and the operator continues to approach the vehicle, the controller 52 sends a signal to the actuator SO to switch the light source 34 from illuminating filament 44 to filament 48 to project light downwardly from the mirror assembly 10 toward the ground adjacent the side door of the vehicle to assist in ingress and egress to the vehicle. The light filament 48 is activated after a predetermined period of time, delta T, has elapsed, such as one or two minutes. Once the operator opens the door of the vehicle, the assist light 34 is turn "OFF".
Next, when the ignition component 56 is activated to the "ON" condition to start the vehicle, the pivot mechanism 28 may automatically pivot the mirror housing 20 from the folded position to the extended use position. When the transmission component 56 is selected to a "DRIVE" position, the mirror housing 20 remains in the extended position and the light source 34 remains "OFF". If the operator places the vehicle transmission in the "REVERSE"
selection, the mirror pane 30 may be powered to the downward viewing position and the controller 52 sends a signal to the actuator 50 to illuminated the light filament 46 to the "ON"
position to assist the vehicle operator in viewing to the rear of the vehicle.
Finally, when the ignition component 56 of the vehicle is turned "OFF" and/or the keyfob component 56 is activated to "LOCK" the vehicle, the pivot mechanism 28 pivots the mirror housing 20 to the folded position and the light source 34 is turned "OFF". It should be appreciated that the controller 52 may be program to control and actuate the pivot mechanism 28 for folding of the mirror housing 20, the articulation of the mirror pane 30 and the activation of the light sources) 34, either independently, combined or as desired for various 3 0 combinations.

The invention has been described in an illustrative manner, and it is to be understood that the terminology, which has been used, is intended to be in the nature of words of description rather than of limitation.
Many modification and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims, the invention may be practiced other than as specifically described.
