ABSTRACT:
A light sensing device for sensing the light output of a bulb in a lamp comprises a fiber-optic light guide having first and second ends and a photodetector. The first end is optically coupled to a projection of a bulb in the lamp and is adapted to pick up light transmitted through the projection from within the bulb. The second is optically coupled to the photodetector such that light exiting from the second end impinges on the photodetector to generate an output indicative of the light output of the bulb.
