DLP2010: are brighter optical engines (>= 500 lumen) possible with this dmd?

Part Number: DLP2010
Other Parts Discussed in Thread: DLP3010, DLP4501

Before hiring an optical engineer to spend time on this I might as well just ask here,

Is the reason WVGA DMD optical engines are limited in their maximum brightness compared to say DLP4050 and DLP4070 optical engines?

One good reason I can think of why brighter off-the-shelf optical engines for low resolution DMDs aren't available is low lumens are meant for smaller projection size applications which means lower pixel per degree value requirements and it won't be usable for most designs (home cinema) to have low resolution DMDs for large projection sizes.

But it could also be a physics and optics law limitation caused by the physical size of the DMD.

I have a rare scenario where I need low resolution but high lumen (>=500) optical engine.

    Armen,

    How much lumens a DMD is capable of is primarily a function of DMD temperature spec. Thus there is no limitation of brightness for any DMD. Each DMD has a temperature spec and as long as this spec is met, customers can design DMD in a system with any brightness. Based on current state of LEDs, optics design, optical/system efficiency we believe DLP2010 based systems can achieve upto 150 lum and DLP3010 based systems can achieve upto 300 lum, but this is just a guideline and can change with advancement in LEDs and innovation in system designs.

    I recommend you take a look at the DLP2010 optical engine reference design for examples, and the DLP2010 datasheet for thermal information:

    I hope this helps.

    Thank you for the explanation. What about the DLP3000 and DLP4501 max lumens?
