Car headlight technology is being used in a new ultraviolet lamp suitable for industrial measurement and quality control.
Philips, which developed the new MPXL gas discharge lamp for cars, has been working with Swedish electronics company Labino to perfect the lamp, which is expected to make UV technology easier to use in industry.
Conventional lamps are difficult to focus, slow to start up, and get hot.
The new UV lamp has light intensity of 17,000 microwatts per square centimetre at a distance of one metre from the light source, compared with 400 microwatts for competing lamps, making it possible to use the lamp in daylight. It generates little heat and can be started in seconds.
Non-destructive testing, tracing leaks, quality control of surface coatings and mineral prospecting are some applications.
Unlike ordinary white light, ultraviolet light illuminates only objects treated with fluorescent pigment. This makes measurement and inspection more accurate.
