        LED Test Fixtures

        The following pictures are of LED test fixtures and contactors for making electrical contact to LEDs designed by Henning Engineering.   These are good examples of the skill and attention to detail that we can apply to your application.   LED test fixture design requires good electro-mechanical design skills as well as some knowledge of optics.   All of the fixtures shown are designed to be interfaced to an integrating sphere and are custom designed to be used with high current large die LEDs.   The fixtures are capable of forward currents in the range of 5A up to 40A.   Making reliable contact at these currents while also keeping the emitting surface unobstructed required some very low profile high current connection schemes.
