*1 In the case of mounting 4 layer glass epoxy base-plate of 70mm×70mm×1.6mm, 37.6mW is reduced at 1°C above Ta=25℃.

*2 In the case of mounting 4 layer glass epoxy base-plate of 70mm×70mm×1.6mm.

*3 Wide VF variation of LED increases loss at the driver, which results in rise in package temperature. Therefore, the board needs to be designed

with attention paid to heat radiation.

*4 This current value is per 1ch. It needs be used within a range not exceeding Pd.
