Littelfuse introduced a series of PLEDs with an ultra-low holding current (just 21mA) that makes the ballast drivers widely used in the output of fluorescent tubes compatible with modern replacement LED strings or tubes. This eliminates the need to scrap otherwise still-working ballasts when replacing fluorescent lighting tubes with LED strings or tubes.
The PLED Ultra Low Holding Current Series also ensures that the ballast will be able to activate the LED string or tube; this is particularly important for ballasts that require the ability to detect high voltage outputs during ignition.
Typical applications for Ultra-Low Holding Current Series PLEDs include replacing both indoor and outdoor fluorescent lighting tubes with LED lighting tubes or strings.
“For our customers, the PLED Ultra-Low Holding Current Series offers them the opportunity to reduce their LED driver cost and avoid discarding still-functional ballasts,” said Meng Wang, product marketing manager for LED Protectors at Littelfuse. “With this series, they can make less expensive LED drivers that are still compatible with the ballast’s output.”
The Key Benefits of the Ultra-Low Holding Current Series PLEDs include:
