ABSTRACT:
A UV-LED is incorporated into a variety of different illumination and radiation devices suitable for illuminating indicia associated with a CD/CDRW/DVD storage medium, gauges, promotional displays, knobs or buttons for automotive or electronic devices, as well as ornaments and air purification by decomposition. The indicia are made of a material responsive to UV emissions to render the indicia visible. The devices may be used in motor vehicles, commercial promotions and displays, electronic devices with the UV-LED's oriented to direct the UV emissions toward the indicia and even positioned in a manner for air purification. Embodiments are presented for UV-LED's from above, the side, and underneath said embodiments of the invention.
