An excimer bulb assembly including an excimer bulb and a pass filter such that the excimer bulb assembly does not emit substantial UV radiation in wavelengths longer than 231 nm, 232 nm, 233 nm, 234 nm or 235 nm. The wavelengths are measured at an incident angle of zero (0) degrees to the filter plane. The pass filter is preferably constructed of a plurality of layers of hafnium oxide, and most preferably constructed of less than seventy five (75)layers of hafnium oxide. The excimer bulb, pass filter, and two electrical connectors may be adapted to form a cartridge which may be adapted to swivel along its main axis. The cartridge may further include a smart chip. The smart chip may retain and store information regarding the assembly and preferably retains hours of use of the excimer bulb.

A light source (1), which has a hollow body (2) closed in a gas-tight manner, which is coated on at least one inner side with a phosphor and is filled with gaseous tritium and emits colored light, the hollow body (2) being arranged in a housing (3) of the light source (1), the light source (1) having at least one body (4) of a colored material which annularly encircles a longitudinal center axis of the light source (1) and the color of which is different from black in daylight, the annularly encircling body (4) being arranged at least on a terminal end region of the housing (3) or at least between the terminal end region of the housing (3) and a light-emitting end face of the hollow body (2).

This application discloses an ultraviolet lamp tube comprising: an outer tube and an inner tube, each installed with an electrode, wherein the outer wall of the outer tube is coated with plated coatings A and B for filtering waves to enable emission of a single-wavelength light from the light source. This application also discloses an ultraviolet lamp tube comprising an inner tube and an outer tube each installed with an electrode, wherein the outer tube is coated with a plated coating A and a reflective coating to enable emission of a single-wavelengthe light with a high luminous efficiency. Through the method of plated coating, the UV lamps disclosed have achieved increased beam angle, improved light output power and luminous efficiency.
