Abstract

A mobile UV-intensity indicator is mounted on a vehicle or a portable article. The UV-intensity indicator includes a UV detector and an indicator such as a display and/or an alarm, and warns of overexposure under UV radiation by marking in the display and/or sounding the alarm.

Claims

1. A mobile UV-intensity indicator for providing updated UV information for a user, said mobile UV-intensity indicator comprising:

a UV sensor for receiving UV light and generating an electric signal in response to an intensity of said UV light; and

an indicator in communication with said UV sensor, generating an indication signal according to said electric signal.

2. The mobile UV-intensity indicator according to claim 1 wherein said indication signal is a visible signal indicating said intensity of said UV light.

3. The mobile UV-intensity indicator according to claim 2 wherein said indicator is a gauge, liquid crystal display (LCD), electro-luminescence (EL) display, vacuum fluorescent display (VFD), light emitting diode (LED), organic light emitting diode (OLED), polymeric light emitting diode (PLED), low-temperature polysilicon liquid crystal display (LTPS-LCD) or seven-segment display.

4. The mobile UV-intensity indicator according to claim 1 wherein said indication signal is a visible signal asserted when a value of said electric signal exceeds a threshold.

5. The mobile UV-intensity indicator according to claim 4 wherein said indicator is a lightening device, gauge, display, photo-chromic unit or electro-chromic unit.

6. The mobile UV-intensity indicator according to claim 1 wherein said indication signal is an audible signal asserted when a value of said electric signal exceeds a threshold.

7. The mobile UV-intensity indicator according to claim 6 wherein said indicator is an alarm or a voice or music sounder.

8. The mobile UV-intensity indicator according to claim 1 wherein said indication signal is a tangible signal asserted when a value of said electric signal exceeds a threshold.

9. The mobile UV-intensity indicator according to claim 8 wherein said indicator is a vibrator.

10. The use of a mobile UV-intensity indicator as recited in claim 1 in a vehicle.

11. The use according to claim 10 wherein said electric signal is transmitted from said UV sensor to said indicator via a vehicular digital bus.

12. The use according to claim 11 wherein said vehicular digital bus is a controller area network (CAN) bus or a vehicle area network (VAN) bus.

13. The use according to claim 10 wherein said vehicle is a car, motorcycle, bicycle, boat or plane.

14. The use of a mobile UV-intensity indicator as recited in claim 1 in a portable article.

15. The use according to claim 14 wherein said portable article is an electronic appliance with a built-in display serving as said indicator of said mobile UV indicator.

16. The use according to claim 15 wherein said electronic appliance is a pager, a cellular phone, a personal digital assistant (PDA) or a handheld computer.

17. The use according to claim 14 wherein said portable article is an electronic appliance with a built-in sounder serving as said indicator of said mobile UV indicator.

18. The use according to claim 17 wherein said electronic appliance is a pager, a cellular phone, a personal digital assistant (PDA) or a handheld computer.

19. The use according to claim 14 wherein said portable article is a watch, a pen or a container.

20. The use according to claim 19 wherein said container is a container of sun block, cosmetic or sunglasses.
