Paper Abstract

The intensity distribution of the whole arc is not uniform in the discharge process of short-arc xenon lamp. Generally, the intensity of the arc is the highest at 0.07×L (L is polar distance) away from the cathode, forming a cathode spot with great brightness. Therefore, short-arc xenon lamp can be regarded as a point source of high brightness, and short-arc xenon lamp is an ideal concentrating light source, which is similar to sunlight in intensity and collimation. Xenon lamp has the characteristics of high radiation power, small spot, high brightness, good stability and instantaneous start-up. The luminous point can be made very small, and the positioning accuracy is high, so it is easy to realize directional reflection. The spectral energy distribution of short arc xenon lamp is close to that of blackbody radiation. The short-arc xenon lamp can be used as an ideal point source for military searchlight, solar simulator and optical experiment. Parabolic reflector is an axisymmetric quadric reflector. It can be used as a reflector for directional xenon lamp because it has equal optical path to the object point on the infinite far axis. According to the characteristics of parabolic reflector, the model of directional xenon lamp is established by TRACEPRO software, and the effects of focal length, aperture, inclusive angle and axial defocusing of directional xenon lamp on illuminance are simulated and analyzed.
