Interesting…but too large for the 20.6 mm diameter light that waits for it.
ADDED: though without the corner LEDs the following 12 would have just 0.42 mm larger diameter than 9….
ADDED: About 10-12A when driven off 16340? A hottie.
^ That looks like exactly what I’m planning on doing: RGBA quadtrix (in an S2+).
I’m hoping to find a better 4-channel driver than the single mode per channel model that kaidomain sells, but even if not, I will enjoy experimenting with these.
That 4x4 E21A requires big 13mm LES class COB optic to work properly. With smaller than 35mm (ideally 50mm) the wiring will interfere and creates artifacts unless special flat wires which is not common is used. With 30mm diameter it’s uses are even more limited. And another reason is the heat spreading factor which is a very important factor for non isolated thermal pads in E21A. Larger the diameter is better. Above thermal simulation shows that to get into BLF output range (8500 lumens in R9080 or 12.000lumens in R70), 0,21mm (6 oz) thick copper trace is needed (with current best IMS available)
A best color mixing are produced with elliptical TIR and VR16S1+2 different CCTs parallel led. I tested sm303+sm653 may be 95% dissolves on both, only minor singularities on edged. Non-elliptical TIR does performing mirred of source.
LES is not my only concern with all my module designs Agro. Voltage flexibility is mainly limits the design. Beam profile can still be altered by optics, easier than voltage.
