The automotive industry uses various types of crash testing every day to evaluate and improve automotive safety. The application of high-speed photography utilizing two- or three-dimensional test analysis is the current tool of choice. While high-speed cameras have become more sophisticated, they cannot solve all problems facing the photographer. Along with camera optics, light is the most critical element in achieving the best pictures, using the desired frame rate and depth of focus.
Since LED technology has become more robust, LED lighting for high-speed photography has become more and more popular over the past couple of years. LED technology offers advantages over conventional HMI lighting solutions. HMI lamps require a couple of minutes of warming-up time as well as a couple for cooling-down before re-start. More convenient, LEDs start instantly. Light is simply there whenever you need it. Additionally, LED are more efficient using lower wattage power supplies.
