<p>A low power, high intensity strobe light employing light emmitting diodes (LED's). A plurality of LED's (14) are electrically connected in series and parallel in a manner to approximate the resistance of a single LED. They are mounted in a box having a reflective inner suface and an opening covered with a lens whereby the light from the LED's (14) is reflected and directed through the lens. The LED's (14) are electrically strobed by a circuit comprising a d.c. power source (10) operably connected to a triggerably constant voltage circuit (22) which in turn, is driven by a multi-vibrator circuit (32) which periodically triggers the constant voltage circuit (22) for only the time duration necessary to cause the LEDS's (14) to emit a high intensity, visually detectable pulse of light.</p> |
