Heat Issues with Tungsten Sockets


PROBLEM: Socket Corrosion

    Even the best Tungsten lamp sockets corrode / expand with heat over time. Vibrations antagonize this situation. Both come together to produce intermittent light-output. (Note: Current-controlled DC power supplies are, more often than not, too slow to compensate.)

    Tungsten/Halogen lamps become so hot that overly-heated sockets and loose connections are all too common to the extent that they cannot be trusted to maintain constant light output. Vibrations of the lamp in its sockets will periodically scrub away the corrosion, causing small changes in socket resistance. These seemingly minute changes produce intermittent light-output visible to the Vision System.


SOLUTION: Light Feedback

    MERCRON's Tungsten Light Controllers use light feedback and AC drive to instantly correct any deviation in intensity, so that the light remains perfect. Moreover, when MERCRON's temperature-compensated PhotoDiode is used with our Tungsten Light Controllers, the light can be held to within a few degrees-Kelvin – no small achievement. (Engineers / Scientists have responded with enthusiasm to the performance of these controllers.)
