LEDs supplied with uniform colour and brightness
CML Innovative Technologies (CML-IT) is providing its customers with a wide range of test and calibration services related to LEDs from what it describes as the world's first private-sector and fully-accredited laboratory in Bad Dürkheim, Germany.
The state-of-the-art laboratory offers sorting of 3mm (T1) and 5mm (T1 3/4) LEDs and IREDs for optimised homogeneity. Cost-effective and fully customised to specific customer needs, CML-IT's LED binning service can achieve uniformity for LEDs in both colour and brightness and improve the appearance of customer end-products. Key target markets are LEDs used for displays and signs, white LED applications such as reading lights, ambient lighting and advertising boards as well as detection applications such as machines and automation, smoke detectors and machine vision.
CML-IT's LED binning is suitable for batches of 1000 pieces up to more than 1,000,000 pieces. The following sorting parameters are available:
- Averaged LED intensity ILED B (photometric [cd] and radiometric [W/sr])
- Dominant wavelength
- Colour co-ordinates (x, y)
- Peak-wavelength
- Centroid wavelength
- Forward voltage
- Forward current
CML-IT's LED intensity and LED luminance standards are used for calibration purposes by world-renowned LED manufacturers, leading suppliers of LED-measurement equipment, research institutes, and major industries - including the automotive sector.
