Abstract
A UV emitter is incorporated into a variety of different illumination devices suitable for illuminating indicia associated with dials on watches, gauges and other instruments, as well as ornaments. The indicia is made of a material responsive to UV emissions to render the indicia visible. The devices may be used in motor vehicles and other devices. In addition, a conductor arrangement is also provided that can be used to support the UV emitter under the transparent cover of watches or gauges, with the UV emitter oriented to direct the UV emissions toward the indicia. Embodiments are presented for UV emitters on top of dials with indicia, laterally from the dials, or even under the dials.
Claims25
In a watch having a case with a dial and a crystal disposed on top of said dial, an illumination apparatus comprising:
- a light emitter including a lensless semiconductor junction adapted to generate light in the UV region and generating a broad UV light beam;
- and
- at least one indicia disposed on said dial, said indicia being adapted and arranged to become visible in response to said UV light beam.
An ornamental device comprising:
- a case having a base and a transparent cover, with an image affixed to said base and visible through said cover, said image including image elements responsive to UV light;
- and
- a light emitter disposed in said base and arranged to form a UV light beam directed to said image.
In a vehicle having at least one device, an illumination apparatus comprising:
- a light emitter including a semiconductor junction without a focusing lens adapted to generate wide UV beam;
- and
- indicia responsive to said UV beam and attached to said device.
An illuminating apparatus for a device having a case with a dial and a transparent cover through which the dial is visible, comprising:
- a conductor arrangement having an arm extending under said transparent cover and having a first end fixed and a second end;
- and
- a light emitter attached to said second end and being supported by said arm in a cantilevered fashion, said light emitter being oriented to direct light toward the dial.
A flashlight comprising:
- an elongated body adapted to hold a battery;
- and
- a UV emitter secured to said body and arranged to selectively produce UV emissions, said UV emitter including a semiconductor junction adapted to generate said UV emissions.
