Imagine that you are doing a surgical procedure on a patient
and the area to operate is less luminous. Mishaps might occur. Thus, in an
operation theatre, the light source is of key importance. It enables you to see
the cavity or internal parts of the patient with utmost clarity.
In earlier days, sunlight was the source for operation. With
the invention of light bulb, things have changed. But, they too caused
problems. Then came the LED light (Light Emitting Diodes) which are currently
in vogue.
