Abstract: A gaseous tritium light source (GTLS), which has a hermetically sealed outer sleeve made of glass, more particularly borosilicate glass. A high durability and lighting intensity is produced due to the fact that at least some sections of the outer sleeve have an outer coating applied directly to the outer surface of the outer sleeve serving as a reflective layer made of a metal, wherein the outer coating has an epitaxial structure and wherein the metal has a reflectance of >70% for visible light.

Abstract: A lighting element with a gaseous tritium light source and an elongated plastic housing that at least partially encloses the gaseous tritium light source with its housing shell and forms a latching element that snaps together with the gaseous tritium light source, which can be inserted into the plastic housing, and holds it in the plastic housing. A rugged lighting element can be produced if the latching element is formed by at least one catch element, which catch element has a radially sprung flexible spring and at least one, preferably two, inwardly oriented snaps with an indentation for snapping together with the gaseous tritium light source.

Abstract: A folding knife and related method include actuating elements for locking or unlocking the blade of the knife. The actuating elements are permanently illuminated or backlit so that the actuating elements are more clearly visible in low light conditions and can therefore be safely operated. Such features for knife applications may provide advantages for particular activities where knives are commonly used, such as for law enforcement and hunting.
