PORTABLE LIGHT WITH SELECTABLE OPTICAL BEAM FORMING ARRANGEMENT

摘要

A portable light may comprise: a light body and a light source supported thereby and selectively energizable for producing light; a switch for selectively energizing the light source; a TIR optical element disposed in front of the light source for receiving the light produced thereby, and form the light into a collimated beam of light, the TIR optical element having a recess in a forward face thereof; and a selectable beam modification element placeable into and removable from the recess in the forward face of the TIR optical element.

1. A portable light comprising:
a light body for receiving a source of electrical power; a light source supported by said light body and selectively energizable for producing light; a switch supported by said light body for selectively energizing said light source from the source of electrical power; a totally internally reflective (TIR) optical element having a rearward end disposed in front of said light source for receiving the light produced thereby, said TIR optical element employing total internal reflection to form light produced by said light source into a collimated beam of light, said TIR optical element having a recess in a forward face thereof; a selectable beam modification element having a size and shape corresponding to the recess in the forward face of said TIR optical element, wherein said selectable beam modification element is placeable into the recess in the forward face of the TIR optical element and is removable from the recess in the forward face of the TIR optical element; and means for removably retaining said selectable beam modification element in the recess in the forward face of said TIR optical element.
