Abstract:
1. A reflector for flashlights and other light emitting objects having a light emitting element, said light emitting element having a light emitting surface, said reflector comprising a generally deep dish shaped reflector member having a reflective inner surface and having a rear vertex end and a forward open end, said reflector member having at least one cross sectional configuration in the form of a parabola formed according to the formula x 2 =(4) (f) (y) where x and y represent points on a Cartesian coordinate system and f is the distance of the focal point from the vertex of the parabola along an optical axis, said optical axis located along a line where x=0, and said vertex located at the point where x=0 and y=0, said reflector member having a circular opening formed at a forward end thereof at the location of a plane of truncation, said circular opening having a diameter D and said circular opening having a center point located on said optical axis, said plane of truncation intersecting said optical axis at a 90 degree angle and at a distance T from said vertex thus creating a reflector with a depth T, said light emitting surface having a center point located at the focal point of the reflector and wherein the ratio of the depth of the reflector T to said diameter of the reflector D is at least 1.2, said focal point being located on said optical axis close to said vertex at a location less than 10% of the distance from the vertex to said plane of truncation.
