Luminous Efficacy in Laser projection

Updated: Jul 19, 2022

If there is a competition of the Luminous Efficacy between different light sources...Guess who’s the winner?


Let's get to know what is luminous efficacy and why we talk about it with laser projection.


Luminous efficacy is a measure of how well a light source produces visible light. It is the ratio of luminous flux to power, measured in lumens per watt (lm/w) in the International System of Units (SI).


The largest advantage of laser diodes is that their peak efficiency occurs at operating currents up to 2,000 times greater than that of LEDs.


Unlike a "so-called laser projector" using a phosphor to generate light, CASIRIS A6 True Three Primary Laser Projector is powered by three primary lasers system (just RGB lasers and not hybrid) to individually generate output light and a spectrum of colors. True Laser projection has ultra high luminous efficacy that can reach 17.8 lm/w.
