Glass Inspection LED Point Light

Very high intensity single point light source

for Automotive Glass defect inspection

The WattWorks LED PointLight concept uses the brightest single-chip High Power LED available and proprietary optics to maximize luminous flux in the inspection area. In order to increase brightness while maintaining single-point-source image sharpness, the LED PointLight uses a proprietary spherical reflecting collar with an aperture positioned to be centered over the LED.  The reflected light escapes from the aperture in the recycling collar and increases brightness into the angular distribution defined by the LED with recycling collar. The result is that the etendue of the LED is not increased so the image remains sharp, while the luminous flux is increased.

LED Advantages over Arc Lamps

  • Continuously variable intensity
  • Remote control on/off Input terminals, instant light response
  • Eliminates Infrared radiation & wasted heat
  • No Ultraviolet radiation improves workplace safety, No High Voltage required
  • Immediate power-on light, no warm up delay
  • Long life 60,000 hours with linear lumen depreciation to 70% of initial Luminosity
  • Eliminates expensive replacement arc-lamp costs and downtime
  • Designed for Continuous Full-Power operation in a factory floor environment
