Abstract

A portable, hand-held, electrically powered, high intensity directed light beam generating device for use as a replacement for a pyrotechnic flare for search and rescue, especially in a marine environment. The light intensity is generated by a xenon strobe flash tube in a covered, mirror reflective housing that allows for a directional beam of light of less than 6 steradians. The limited radiation light direction provides a safe optical solution for the user to prevent eye damage while increasing the beam intensity and range. The light and illumination section surrounding the strobe flash tube includes thermally conductive paths for the heat generated by the flash tube to be transmitted to the outside of the housing.
