Blast shield for the lens of a light source
Disclosed are implementations of a blast shield configured to protect the lens of a light source, such as a flashlight or laser illuminator, from carbon and other debris generated by the discharge of a firearm to which the light source is attached. The blast shield includes a sidewall positioned to shield the lens from carbon and debris discharged from the muzzle, from ports of a muzzle device, or from gaps between tines of a muzzle device affixed to the firearm.
1 . A blast shield configured to protect a lens of a light source, the blast shield comprising:
a sidewall having a partial cylindrical shape defined by a first lateral edge and a second lateral edge;
a first longitudinally extending rib configured to deflect gases away from the lens, wherein the first longitudinally extending rib is positioned adjacent to the first lateral edge of the sidewall; and
a second longitudinally extending rib configured to deflect gases away from the lens, wherein the second longitudinally extending rib is positioned adjacent to the second lateral edge of the sidewall;
wherein the sidewall extends from a portion of the light source that surrounds the lens, forward of the lens, and is oriented substantially perpendicular to the lens.
2 . The blast shield of claim 1 , wherein the sidewall and the portion of the light source that surrounds the lens are formed as a unitary piece.
3 . The blast shield of claim 1 , wherein the first longitudinally extending rib extends between a front edge and a rear edge of the blast shield, and the second longitudinally extending rib extends between the front edge and the rear edge of the blast shield.
4 . A blast shield configured to protect a lens of a light source, the blast shield comprising:
a curved sidewall defined by a first lateral edge and a second lateral edge;
a first longitudinally extending rib configured to deflect gases away from the lens, wherein the first longitudinally extending rib is positioned adjacent to the first lateral edge of the curved sidewall; and
a second longitudinally extending rib configured to deflect gases away from the lens, wherein the second longitudinally extending rib is positioned adjacent to the second lateral edge of the curved sidewall;
wherein the curved sidewall extends from a bezel of the light source, forward of the lens, and is oriented substantially perpendicular to the lens.
5 . The blast shield of claim 4 , wherein the curved sidewall and the bezel of the light source are formed as a unitary piece.
6 . The blast shield of claim 4 , wherein the first and second longitudinally extending ribs each extend between a front edge and a rear edge of the blast shield.
7 . The blast shield of claim 4 , wherein the curved sidewall has a partial cylindrical shape.
8 . A blast shield configured to protect a lens of a light source, the blast shield comprising:
