Abstract

A system for dynamically projecting a logo onto a surface includes a light source, moveable lenses, and an actuator. The light source emits light toward the surface. The lenses are positioned with between the light source and the surface, with each lens having multiple transparent portions configured to permit some of the emitted light to pass through the lens in a corresponding light pattern. Each corresponding light pattern forms a different part of the logo. The actuator moves the lenses with respect to the emitted light in response to a control signal to thereby cause projection of the logo onto the surface. A vehicle includes a body having a door, road wheels in contact with a road surface, and the system which projects the logo onto the road surface proximate the door. The controller may be programmed to execute a method for projecting the logo.

First claim

The invention claimed is:

1. A system for dynamically projecting a logo onto a surface, the system comprising:
a light source configured to emit light toward the surface;
a plurality of rotatable lenses positioned between the light source and the surface, the lenses each being a disc or a plate and having a painted, etched, or plated surface forming an opaque portion, each lens including multiple transparent portions configured to permit some of the emitted light to pass therethrough in a corresponding light pattern, wherein each of the corresponding light patterns forms a different constituent part of the logo; and
an actuator operable for rotating the lenses with respect to the emitted light in response to a control signal to thereby cause the logo to be progressively constructed and projected onto the surface over a calibrated duration.

2. The system of claim 1 , wherein the light source includes a plurality of light-emitting diodes.

3. The system of claim 1 , wherein the transparent portions of the lenses are surrounded by an opaque portion configured to block all of the emitted light that does not pass through the transparent portions.

4. The system of claim 1 , wherein the control signal is a radio frequency signal.

5. The system of claim 1 , wherein the system is connected to a body of a vehicle in contact with a road surface, and wherein the surface is the road surface.

6. The system of claim 1 , further comprising a controller programmed to detect a predetermined condition and generate the control signal only when the predetermined condition is detected.

7. The system of claim 1 , further comprising a controller configured to command positioning of each of the lenses according to a calibrated sequence such that the logo is progressively constructed and projected onto the surface in different stages over the calibrated duration.

8. The system of claim 1 , further comprising a projector lens having a convex outer surface, wherein the plurality of lenses are positioned between the light source and the projector lens.

9. A vehicle comprising:
a body having a door;
road wheels in contact with a road surface; and
a system operable for dynamically projecting a logo onto the road surface, wherein the system includes:
a light source configured to emit light toward the road surface proximate the door;
a plurality of rotatable lenses positioned between the light source and the road surface, the lenses being circular discs or plates each having a painted, etched, or plated surface forming opaque portions, and each lens including multiple transparent portions configured to permit some of the emitted light to pass therethrough in a corresponding light pattern, wherein each of the corresponding light patterns forms a different constituent part of the logo;
an actuator operable for individually rotating the lenses with respect to the emitted light in response to a projection control signal to thereby cause projection of the logo onto the road surface; and
a controller programmed to detect a predetermined condition, and to generate the projection control signal in response to detection of a predetermined condition, wherein the projection control signal commands a positioning of each of the lenses according to a calibrated sequence such that the logo is progressively constructed from the constituent parts and projected onto the road surface in different stages over a calibrated duration.

10. The vehicle of claim 9 , wherein the transparent portions of the rotatable lenses are surrounded by an opaque portion configured to block all of the emitted light that does not pass through the transparent portions.

11. The vehicle of claim 9 , further comprising a projector lens having a convex outer surface, wherein the plurality of rotatable lenses are positioned between the light source and the projector lens.

12. A method for dynamically projecting a logo onto a surface via a logo projection system, the method comprising:
providing a plurality of rotatable lenses between a light source and the surface, wherein each lens is a circular disc or plate having a painted, etched, or plated surface forming opaque portions, and each lens has multiple transparent portions, the transparent portions of a respective one of the lenses are configured to permit some of the emitted light from the light source to pass through the respective lens in a corresponding light pattern, and each of the corresponding light patterns forms a different constituent part of the logo;
receiving input signals, via a controller, that are indicative of a predetermined condition;
activating a light source via the controller in response to the received input signals to thereby cause the light source to emit light; and
transmitting projector control signals to one or more actuators to cause the actuators to sequentially rotate the lenses, starting with one of the lenses that is positioned closest to the light source, to thereby cause the logo to be progressively constructed from the constituent parts of the logo over a calibrated duration until the logo is fully constructed on the surface.

13. The method of claim 12 , further comprising:
projecting the fully constructed logo onto the surface via the system for another calibrated duration; and
transmitting the projector control signals to the actuators to cause the actuators to sequentially rotate the lenses, starting with one of the lenses that is positioned closest to the surface, to cease projection of the logo onto the surface.

14. The method of claim 12 , wherein receiving input signals includes receiving a radio frequency signal from a remote device.

15. The method of claim 14 , wherein activating a light source includes energizing a plurality of light-emitting diodes arranged on or within a body of a vehicle in contact with a road surface, the remote device is a key fob of the vehicle, and the surface is the road surface.

16. The method of claim 15 , wherein the body includes a rear fascia positioned proximate a rear door or light gate of the vehicle, and wherein the plurality of light-emitting diodes are positioned on or within the rear fascia.
