2.9 Optical Engine Requirements

The DLP4620SQ1EVM can be coupled to an optical engine (not included) to implement a head-up display function or an automotive interior projection system. The detailed requirements of the optical engine are beyond the scope of this document, but the optical engine must 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 DLP4620S-Q1 DMD. The photodiode is used to control white point and brightness output. A heat sink for the DLP4620S-Q1 DMD can be needed for operation in high temperature ambient environments, but is not included in the DLP4620S-Q1 Electronics EVM.

Similarly for the DLP4621Q1EVM, optics and mechanics are not included in the kit.

When choosing your LED or laser component (not included with this EVM) the end user must consult the data sheet supplied by the manufacturer of the illuminator to identify the EN62471 Risk Group Rating and review any potential eye hazards associated with the illuminator 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.

REACH-Affected Components
