Claim 1

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. 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.
