    Abstract: Apparatus for optically testing LEDs or other light-emitting components in a wide variety of test environments and to the degree necessary pertinent to the type(s) of faults encountered. In one embodiment, the present invention includes one or more fiber optic probes coupled to a multi-mode sensor unit, incorporating a photo-sensor coupled to a processor which may be programmed to provide a variety of test modes including simple on/off testing, color determination, color matching, wavelength and relative intensity among others. An extremely high sensitivity test mode is also provided for testing LEDs which emit very low intensity light in the micro-candela range in products such as automobile/aircraft cockpit control panel lighted push-buttons for night-time viewing. The multi-mode sensor unit operates over a wide dynamic range and is capable of accurately testing LEDs that may be very dim to very bright without adjustment. In another embodiment, a voltage protection circuit is provided which enables the multi-mode sensor unit to safely operate from a supply voltage in the range of approximately 5 volts DC to approximately 40 volts DC while protecting the multi-mode sensor unit from a potentially damaging overvoltage condition. The voltage protection circuit also protects the multi-mode sensor unit against potential damage caused by reverse polarity voltage spikes, or accidental steady-state reverse polarity voltages.
