A new light source (e.g. LEDs) enables new designs in all or some key elements within diagnostic instruments. New light sources allow improvements in life of light source, infra red emitted, power consumption, color temperature, light flux directionality, simplification of optics design, adaptation of light flux directionality, and overall constructional simplification. The new light source allows for the replacement of some or all of the components designed for incandescent filament bulbs. The improved light source may allow for either an entirely new design of all or some core modules of the instrument, or by alteration of pre-existing modules.
