Compact, low-cost & long-lifespan, distributed-switch LEDs
What is NeoLED?
NeoLED is CEA-Leti's world-first solution that powers LEDs directly from a domestic outlet, without any adaptor.
NeoLED offers a real-time update of serial/parallel configuration of LEDs. LEDs in series are continuously adjusted to make sure their supply voltage matches the outlet voltage. This technology eliminates the need for bulky AC/DC power supply adaptors.
Moreover, this technology leverages only low-voltage and low-cost transistors distributed along the light fixture, on the same PCB that supports the LEDs.
NeoLED technology can be used for both high- and low-power applications.
It improves several lighting applications, including:
LEDs are continuously powered—low-voltage parallel configuration—which translates into a significant reduction of the filtering capacity, and results in more chemical capacities. High-voltage transistors are no longer required, because of NeoLED's distributed and low-voltage switching modules. NeoLED helps reduce energy losses and costs.
In 2019, CEA-Leti researchers will work on a LED image projector based on power LEDs, with low-resolution images combined with a powerful luminous intensity and a direct 110 or 230 VAC voltage supply. This system will both light efficiently and project images without the need for a low voltage power supply unit having a very strong current, nor a driving matrix.
