Simple LED (Light Emitting Diode) circuit diagram. In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED.
A lens controller is device that controls motorized photographic lens functions such as zoom, focus, and iris opening . [1] Lens controllers can be found in still camera photographic lenses and as stand-alone units in machine vision , remote sensing , optoelectronics systems, and security applications.
An LED array may include controlling circuits within the same package, which may range from a simple resistor, blinking or color changing control, or an addressable controller for RGB devices. Higher-powered white-emitting devices will be mounted on heat sinks and will be used for illumination.

A ring flash works on a microscope in much the same way as it does on a camera; it reduces reflections while bathing the subject in light.
