Lighting Files
A lighting file is a text file that contains information about a light, such as the type and color of
the light, maximum current limit, and maximum strobe duty cycle. Lighting files have the
extension
.ild
. MAX and Vision Builder AI use lighting files to ensure that the current limits
and duty cycle of your light are not exceeded when the light is used with the Direct Drive lighting
controller. Lighting files exist in four levels of certification:
•
Digitally Signed by National Instruments
—The information contained within the
lighting file has been verified as correct and safe by National Instruments. Contact National
Instruments for support regarding this lighting data file or the light to which it refers.
•
Digitally Signed by a Third-Party Company
—The information contained within the
lighting file has been verified as correct and safe by the specified third-party company.
Contact the third-party company for support regarding this lighting data file or the light to
which it refers.
•
Not Digitally Signed
—The information contained within the lighting file meets the
requirements of Direct Drive lighting; however, it has not been verified that the information
is safe to use with the specified light. Use this file at your own risk.
•
Invalid
—The information contained within the lighting file is unusable because the data
does not meet the requirements of Direct Drive lighting, the data describing the light is not
in the proper syntax, or the digital signature has been altered.
In digitally signed lighting files, the current limit and duty cycle limit are encoded as part of the
signing process. The limits in signed lighting files are not human-readable. Modifying a signed
lighting file will invalidate the signature and render the file unusable.
