Radar effect system and method for instrument cluster gauge
View Patent ↗A lighting system includes a display, a pointer, a motor, a lighting element, a lens, and a coating. The display has first and second opposed sides, with the pointer at least partially disposed on the first opposed side of the display, and the motor disposed on the second opposed side of the display for moving the pointer. The lighting element disposed within the motor on the second opposed side of the display lights the pointer. The lens is disposed on the first opposed side of the display with the pointer at least partially disposed between the first opposed side of the display and the lens. The coating, disposed on an underside of the lens facing the pointer and the display, is made of a material which when excited by light emits light onto the display creating a shadow of at least a portion of the pointer on the display.
1. A lighting system comprising:
a display having first and second opposed sides;
a pointer at least partially disposed on the first opposed side of the display;
a motor disposed on the second opposed side of the display for moving the pointer;
a lighting element disposed within the motor on the second opposed side of the display for lighting the pointer, the motor comprising a shaftless stepper motor and the lighting element being disposed within a shaftless portion of the shaftless stepper motor;
a lens disposed on the first opposed side of the display with the pointer at least partially disposed between the first opposed side of the display and the lens; and
a coating disposed on an underside of the lens facing the pointer and the display, wherein the coating is made of a material which when excited by light emits light onto the display creating a shadow of at least a portion of the pointer on the display.
2. The lighting system of claim 1 wherein the lighting system comprises a portion of a vehicle.
3. The lighting system of claim 1 wherein the display comprises an instrument cluster gauge.
4. The lighting system of claim 1 wherein the lighting element comprises a light-emitting diode.
5. The lighting system of claim 1 wherein the lens is transparent.
6. The lighting system of claim 1 wherein the coating comprises Phosphorous.
7. The lighting system of claim 1 wherein the coating comprises a decay rate which provides a ghosting effect by creating a trailing moving shadow of the pointer on the display.
8. A vehicle instrument lighting system comprising:
a vehicle gauge display having first and second opposed sides;
a pointer at least partially disposed on the first opposed side of the vehicle gauge display;
a shaftless stepper motor disposed on the second opposed side of the vehicle gauge display attached to the pointer for moving the pointer;
a lighting element disposed within the shaftless stepper motor on the second opposed side of the vehicle gauge display for lighting the pointer;
a lens disposed on the first opposed side of the vehicle gauge display with the pointer at least partially disposed between the first opposed side of the vehicle gauge display and the lens; and
a coating disposed on an underside of the lens facing the pointer and the vehicle gauge display, wherein the coating is made of a material which when excited by light emits light onto the vehicle gauge display creating a shadow of at least a portion of the pointer on the vehicle gauge display.
9. The vehicle instrument lighting system of claim 8 wherein the lighting element comprises a light-emitting diode.
10. The vehicle instrument lighting system of claim 8 wherein the lens is transparent.
11. The vehicle instrument lighting system of claim 8 wherein the coating comprises Phosphorous.
12. The vehicle instrument lighting system of claim 8 wherein the coating comprises a decay rate which provides a ghosting effect by creating a trailing moving shadow of at least the portion of the pointer on the vehicle gauge display.
13. A method of lighting a display comprising:
moving a pointer at least partially disposed on a first side of a display relative to the display with a motor disposed on a second side of the display, wherein the second side of the display is opposed to the first side of the display;
lighting the pointer with a lighting element disposed within the motor on the second side of the display, wherein the motor comprises a shaftless stepper motor and the lighting element is disposed within a shaftless portion of the shaftless stepper motor;
transmitting light from the pointer into a coating disposed on an underside of a lens facing the pointer and the display, wherein the lens is disposed on the first side of the display with the pointer at least partially disposed between the lens and the first side of the display; and
exciting the coating with the transmitted light from the pointer and emitting light from the coating onto the first side of the display.
14. The method of claim 13 wherein the display comprises a portion of a vehicle.
15. The method of claim 13 wherein the display comprises an instrument cluster gauge.
16. The method of claim 13 wherein the lighting element comprises a light-emitting diode.
17. The method of claim 13 wherein the lens is transparent.
18. The method of claim 13 wherein the coating comprises Phosphorous.
19. The method of claim 13 further comprising the emitted light, emitted from the coating, providing a ghosting effect by creating a trailing moving shadow of at least a portion of the pointer on the display.
20. The method of claim 19 further comprising a material of the coating being chosen based on its decay rate to provide the desired ghosting effect.
