Abstract
Equipment including a lamp for producing UV light in the range 300-314 nm wavelength having spectral power in the range 302-307 nm wavelength across a 5 nm bandwidth of 40% of overall spectral power and spectral power in the range 307-312 nm of 40% of overall spectral power with a reflector of 90% reflectance in the range 300-314 nm wavelength. A key operated arming switch is series connected to a timer switch.
Claims11
Equipment for producing ultraviolet (UV) light, comprising:
- (a) an electromagnetic wave generator lamp operable upon connection to a source of electrical power to emit ultra violet (UV) radiation in the range of 300-314 nanometers (nm) wavelength having spectral power in the range of 302-307 (nm) wavelength being measured across a five (5) nm bandwidth of wavelength of at least 40% of the overall spectral power of the emitted irradiance of the lamp and the spectral power in the range of 307-312 nm of at least 40% of the overall spectral power;
- (b) a timed switch electrically series connected to the said generator;
- and, operative to de-energize the wave generator after a predetermined interval;
- (c) a user operated switch series connected with the timed switch;
- and,
- (d) a reflector providing 90% reflectance in the range 300-314 nm wavelength.
