Key Notes: ·     Documentation of LED Driver provided during original certification

·     LED Drivers are typically Recognized

·     Documentation of critical parameters (input/output electrical parameters, environmental parameters, temperature parameters, etc.)

·     Inclusion of substitution allowance

·     Documentation of LED Driver provided during original certification

·     LED Drivers are typically Listed

·     Documentation of critical parameters (input/output electrical parameters, environmental parameters, etc.)

·     Inclusion of substitution allowance

 

Key Differences: ·     Includes consideration for temperatures both on the case of the LED Driver as well as information on how hot the LED Driver internal components are getting.

·     Temperature information is used to ensure internal components are not exceeding rated temperatures and will ultimately help reliability and lifetime.

·     Manufacturers may also rely on temperature information for warranty purposes.

·     Does not include temperature parameters in the consideration.

·     Program relies on component safety during failure mode.

·     Greater flexibility afforded due to removal of temperature considerations.

·     Provides a UL Listing

·     Potential for compromised performance, lifetime and reliability with temperature considerations removed.
