(1) Luminus SFT-03X-W, White LED, LED
PWM Configuration = 450 of 1023, duty cycles: R0%, G100%, B0%. Any RGB channel
can be used for monochromatic operation, but the green channel is used as the TI
default.
(2) Efficiency defined as: (Luminous
Flux x 100%)/Calculated Raw Lumens.
(3) Efficacy defined as: White ANSI
Lumen/LED Power.
WARNING: When choosing the LED component (not included with this
EVM), the user must consult the LED data sheet supplied by the LED manufacturer to
identify the EN62471 Risk Group Rating and review any potential eye hazards
associated with the LED chosen. Always consider and implement the use of effective
light filtering and darkening protective eye wear and be fully aware of surrounding
laboratory-type set-ups when viewing intense light sources that can be required to
minimize or eliminate such risks to avoid accidents related to temporary
blindness.
The block diagram is shown in Figure 2-1.
In this application, the Sitara MCU
reads video data directly from a flash memory to display on the DMD. The Sitara MCU
also coordinates the illumination timing to coordinate with the displayed video
content.
