DLPLCR4500EVM: Illuminance of the LEDs

Part Number: DLPLCR4500EVM

Section 3.2.4 in the User's Manual has figures showing an exemplary performance of the LEDs at different currents. Is it correct, that the illuminance of the Green LED is almost 10 times higher than that of the Blue LED? I.e. the Green LED is stated to have an illuminance above 1000Lx at 4A, while the blue LED only has 110Lx at 4A.

    Hello,

    The information is correct. The contribution towards luminescence varies with wavelength. These optical engine use Q8WP LED from Osram. Please refer the datasheet of these LEDs at Osram's site for details on this.

    The green LED has biggest impact on the illumination.

    regards,
