LED Power Driver

A Light Emitting Diode (LED), with low power consumption, compact size, long life
duration and versatility, is ideal for lighting and illumination applications. LEDs have
found its appl ications in LCD monitor/TV backl ights, street l ighting, automobil e
lighting, interior lighting, outdoors large screen displays, consumer electronics and
various other applications.
LED power drivers are used to provide the power to the LEDs, and are usually
designed as a constant current source due to the light emitting characteristics of
the LEDs. Although LED power drivers' functions and characteristics differ from
the general switch mode power supply (SMPS), the components used, the design
topology and the testing requirements are very similar. Chroma is able to provide LED
testing solution based on its thirty years of experience in providing power electronics
testing solutions. These solutions include : programmable AC and DC Sources, high
precision Power Meters, and LED Load Simulator specifically designed for LED power
drivers. Chroma is also able to provide Automated Test Systems suitable for R&D, QA
qualifications and mass production
