Abstract：In the paper, an Anti-threat lighting LED torch with the type of ZY4623 was investigated for a better understanding and application of Anti -threat lighting products.The blasting flash frequency, colorimetric and photometric parameters, such as light spectrum, luminous flux, colour temperature, colour rendering index, chromaticity coordinate and the light spatial distribution curve , were tested and analyzed. The results show that the color coordinates is (0.2952, 0.2996), the color temperature is 7624K, the color rendering index reaches 76.8; flashing frequency is 7.6 Hz.The light distribution curve is a narrow strip shape, the light intensity distribution in the light irradiation direction with the small solid Angle range which can realize remote light.Therefore it’s suitable for the application of anti -threat lighting at night.
