Lighting element for a firearm or sight
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.
1. A lighting element for a firearm or sight, comprising:
a gaseous tritium light source; and
an injection-molded plastic housing that at least partially encloses the gaseous tritium light source, wherein the plastic housing at least partially consists of a polyamide 12 (PA12)-based or polycarbonate (PC)-based transparent plastic.
2. The lighting element according to claim 1 , wherein the polyamide 12 (PA12) base is selected from the group consisting of PA 12/MACMI, PA MACMI/MACMT/12, and PA12 GF30 as well as mixtures or blends of one or more of these plastics.
3. The lighting element according to claim 1 , wherein the polycarbonate (PC) base is selected from the “PC-HT” group as well as mixtures or blends of one or more of these plastics.
4. A sight comprising the lighting element according to claim 1 .
5. The lighting element according to claim 1 , wherein a first end of the plastic housing forms an optical lens.
6. The lighting element according to claim 5 , wherein the lens is plano-convex, convex-convex, or concave-convex.
7. The lighting element according to claim 5 , wherein an inner radius of the lens and an outer radius of the lens are different from each other.
8. The lighting element according to claim 1 , wherein a first end of the plastic housing has an optical lens, and the lens is injection-molded onto the plastic housing or the plastic housing is injection-molded onto the lens using a 2-component injection-molding process.
9. The lighting element according to claim 8 , wherein the lens is plano-convex, convex-convex, or concave-convex.
10. The lighting element according to claim 8 , wherein an inner radius of the lens and an outer radius of the lens are different from each other.
11. The lighting element according to claim 10 , wherein the inner radius and/or the outer radius is/are in a range from 1.25 to 4 times half of a diameter of the gaseous tritium light source.
12. The lighting element according to claim 1 , wherein the plastic has pigments, and the pigments are selected from the group consisting of color pigments, luminous pigments, fluorescent pigments, phosphorescent pigments, and combinations thereof.
13. The lighting element according to claim 1 , wherein the gaseous tritium light source is integrally bonded to the plastic housing with an adhesive.
14. The lighting element according to claim 13 , wherein the adhesive is white.
15. The lighting element according to claim 1 , wherein the gaseous tritium light source has a hermetically sealed glass tube as its outer shell.
16. The lighting element according to claim 1 , wherein the injection-molded plastic housing is elongated.
17. The lighting element according to claim 1 , wherein a see-through region of the plastic housing at least partially consists of the polyamide 12 (PA12)-based or polycarbonate (PC)-based plastic.
18. A firearm comprising the lighting element according to claim 1 .
19. A firearm comprising the sight according to claim 4 .
