Sharp has added LED arrays with efficiency up to 99 lm/W,up to 1,550 lm(typical)output,and with CRI up to 82(typical).
Part of the Mini Zenigata range and called GW5BxxxK05,luminous flux is between 1,150 and 1,550 lm(typical).
The 15W modules have a forward voltage of 39V at 400mA"however,you can also operate the arrays with increased constant current of up to 440mA to achieve a luminous flux of up to 1,650 lm,"said Sharp.
Inside are 48 dies in a matrix of four parallel strings of 12.
New for these devices is a round emissive surface to allow more compact optical designs.
"The circle has a diameter of 8mm and is filled up to the edge with dies,"said Sharp.
The package is the standard Mini Zeni 15x12x1.6 mm,made from aluminium oxide.
Colour temperatures span warm to cool with a 2,700 to 5,000K range,with two ranges:>80CRI and>90CRI.
