Design of LED Viewbox Controlled by Induction

The current status of industrial X ray film viewbox was analyzed, a new design concept of viewbox was put forward. High intensity light emitting diode (LED) was selected as light source for the production of high brightness LED lights viewbox, which was controlled by induction. It was characteristic of high brightness, longevity, energy-saving and environmental protecting. This viewbox could be widely used in film observation and evaluation in the field of radiation detection.
