Abstract
The invention comprises an ultraviolet nightlight configured for illuminating walkways and/or for highlighting scorpions. In one embodiment, a nightlight is configured with an ultraviolet source. Photons emitted or radiated by the nightlight interact with a scorpion causing the scorpions to fluoresce. The fluorescing scorpion is readily observed by a human at night, thereby alerting the human and providing a measure of security and/or safety. The nightlight is optionally configured in the ultra violet and visible light range, with the visible component comprised predominantly of blue light. The emitted blue light is used to light or illuminate corridors and/or obstacles with a cool comforting color.

An apparatus configured for providing light, comprising:
- a nightlight, comprising:
- a housing comprising a front side and a back side;
- an alternating current outlet plug affixed to said back side of said housing;
- a case back affixed to said back side of said housing;
- a light diffuser affixed to said front side of said housing;
- and
- a source at least partially enclosed in said housing, said source configured to during use:
- emit a first amount of light from about 350 to about 400 nanometers;
- and
- emit a second amount of light from about 400 to about 700 nm,
- wherein said first amount of light exceeds said second amount of light,
- wherein said source comprises a set of light-emitting diodes, said set comprising at least two light-emitting diodes, and
- wherein a first light-emitting diode of said set of light-emitting diodes is configured to provide a first peak spectral intensity at a wavelength less than 400 nm, wherein a second light-emitting diode of said set of light-emitting diodes is configured to provide a second peak spectral intensity at a wavelength greater than 400 nm.
