A lighting element for a firearm or sight with a gaseous tritium light source and with an injection-molded plastic housing, wherein the plastic housing at least partially encloses the gaseous tritium light source. High mechanical ruggedness can be achieved if the plastic housing at least partially consists of a polyamide 12 (PA12)-based or polycarbonate (PC)-based plastic.

Embodiments of the present disclosure are directed to a phototherapy eye device. In an example, the phototherapy eye device includes a number of radioluminescent light sources and an anchor. Each radioluminescent light source includes an interior chamber coated with phosphor material, such as zinc sulfide, and containing a radioisotope material, such as gaseous tritium. The volume, shape, phosphor material, and radioisotope material are selected for emission of light at a particular wavelength and delivering a particular irradiance on the retina (when implanted in an eyeball). The wavelength is in the range of 400 to 600 nm and the irradiance is substantially 10.sup.9 to 10.sup.11 photons per second per cm.sup.2.

The invention relates to a sight device (1), in particular a reflector sight or telescopic sight, which sight device has a lighting apparatus (2) for producing or illuminating a target mark, wherein the lighting apparatus (2) comprises an light guide (3) made of photoluminescent, in particular fluorescent material and a radioluminescent light source (7) coupled to the light guide (3), wherein the light guide (3) is designed to receive ambient light and convert said ambient light into photoluminescence light along at least one segment (4) of the longitudinal extent of the light guide, and wherein the absorption spectrum (10) of the photoluminescent material of the light guide (3) and the emission spectrum (9) of the radioluminescent light source (7) in the visible range can both be characterized by a spectral bandwidth and a center wavelength. In order to increase the luminance of the lighting apparatus and thus the visibility of the target mark, the center wavelength of the emission spectrum (9) of the radioluminescent light source (7) is greater than the center wavelength of the absorption spectrum (10) of the photoluminescent material of the light guide (3).
