How to open the file Philips Violet LED board.pcb

Other Parts Discussed in Thread: DLP4500, DLP2010NIR, DLP7000UV, DLP9500UV, DLP4500NIR

Hello  team,
I'v got a problem about opening the file "Philips Violet LED board.pcb" from the download link "http://www.ti.com/lit/df/tidc573/tidc573.zip",which about how to Modify the DLP LightCrafter 4500.
I have try to use Protel 99 SE , PowerPCB 5.0,pads9.3 and Altium Designer open or import it,but all failed and reminded ".pcb not recogined" or "Job not compatible with current version of program".It seems to be a binary file and I wonder konw which pcb soft created it and open it?

Best Regards,

  • Hello Bee,

    We used ExpressPCB: http://www.expresspcb.com/expresspcb/.

  • Hello Eric,

    thank you for your answer, now I can open it.
    I have answer question.What is the limited Wavelength Range of the DLP4500?
    Can a 390nm UV LED takes the place the light engine's led ? Will it work well?
    if it works what is the limited power of the UV led ,because I wonder if it'll do damage to the DLP4500?

    Best Regards,

  • Hello Bee,

    The specifications for wavelength range are provided in the DLP4500 data sheet on page 14.  You will find the DLP4500 is optimized to operate between 420nm and 700nm.  Please also see the Wavelength Transmittance Considerations for DLP® DMD Window application note.  It provides information on the DLP4500 window transmittance.  

    You can experiment with other wavelengths, but exceeding the data sheet specifications could shorten the lifetime performance of the device.

    Best regards,

  • Hello Eric,

    I have doubts on understanding Wavelength Transmittance Considerations for DLP® DMD Window application note on page one.

    The DMD windows are designed for three different transmission regions.
    • Ultraviolet (UV) light: 320 to 400 nm
    • Visible light: 400 to 700 nm
    • Near infrared (NIR) light: 700 to 2500 nm
    The coating used depends on the application. UV windows have special AR coatings designed to be more
    transmissive for ultraviolet wavelength, visible coatings for visible DMDs, and NIR coatings for NIR DMDs.

    Is that means each Window,Corning 7056 DMDs window and Eagle XG DMDs window ,has its three diffent type AR coatings.
    So there are six pruducts of the combination:
    Corning 7056 DMDs window with special AR coatings for UV,
    Corning 7056 DMDs window with visible coatings ,
    Corning 7056 DMDs window with NIR coatings,
    Eagle X DMDs window with special AR coatings for UV,
    Eagle X DMDs window with visible coatings ,
    Eagle X DMDs window with NIR coatings.

    And the wavelength range depands on each windows' coatings Is that right?

  • Hello Bee,

    Yes, there are six combinations possible, but we do not offer every combination for every DLP DMD.  Most DMDs have visible coatings.  DMDs with a NIR ending (e.g. DLP4500NIR and DLP2010NIR) have AR window coatings for NIR and DMDs with a UV ending (e.g. DLP9500UV and DLP7000UV) have AR window coatings for UV.  

    Yes, the wavelength range depends on each DMD AR window coating.  Please refer to the DMD data sheet to confirm if the window is Corning 7056 or Eagle XG, if you are not sure.  For example, the window information for the DLP4500 is located in Table 6 on page 24 in the data sheet.

    Regards,
