Texas Instruments DLP5532HBQ1EVM, User Manual, Page: 15 / 21

3 Optical Engine Requirements and Specifications
The DLP5532HBQ1EVM can be coupled to an optical engine (not included) to implement an automotive interior
projection system. The detailed requirements of the optical engine are beyond the scope of this document, but
the optical engine have separate red, green and blue illuminators. These are typically LEDs. The optical engine
also needs to provide a photodiode in the illumination path before the DLP5532-Q1 DMD. The photodiode is
used to control white point and brightness output.
Depending on the specifics of a customer design, customers must perform thermal analysis and simulation to
determine the best type of cooling method required. The DLP5532HBQ1EVM supports three fans and active
cooling feedback but the external fans themselves are not included in the DLP5532HBQ1 Electronics EVM. A
heatsink for the DLP5532-Q1 DMD can also be needed for operation in high temperature ambient environments,
but is not included in the DLP5532HBQ1EVM
WARNING
When choosing your LED component (not included with this EVM) the end 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 setups when viewing intense light sources that may be required to
minimize or eliminate such risks to avoid accidents related to temporary blindness.
