There are many standards or agency programs for regulation of LED drivers, including both voluntary and mandatory programs. Today we will look at some of the many driver standards and governmental agency requirements designers need to be aware of.
The list should include FCC requirement 47 CFR part 15, Class A and Class B, Harmonic Emission limits ANSI C82.77-2002 or IEC 61000-3-2, safety standards UL 8750 or IEC 60650 Part 1, Line Transient protection IEEE C62.41.1991, Class A. or Class A audible noise. LM-80: specifies procedures for determining lumen maintenance of the LEDs and LED modules, not the luminaries. LM79 specifies procedures for measuring luminous efficacy. TM-21 specifies the method to determine expected operating life. Last, but not least, NEMA SSL 1 Electronic Drivers for LED Devices Arrays or Systems.
Today, we listed many regulatory and industry standards that designers need to account for in order to understand the design constraints of any given project for reducing power losses, power factor correction and low THD in the LED driver. While there is a lengthy list of applicable standards, examining the Energy Star program requirements highlights many of the LED driver design requirements.
