A shutter slice and a diaphragm are mounted on the top surface of multi-function support, and pivot around a shaft projected thereon. Two movable rods of the solenoid valves are coupled with the shutter slice and diaphragm to drive them passing a light path, an axis through the lens, for controlling time and quantities of light projected through the lens. A housing cover encases the lens, the multi-function support, and a spring into the lens housing.
