When a light emitting diode is forward biased (turned on), the electrons are able to recombine with the holes of electrons inside of the device, releasing the energy as photons. This effect is called electroluminescence and the color of the light (corresponding to the energy of the photon) is determined by the bandgap of semiconductor. An LED is often small in area (less than 1 mm2), and integrated optical components may be used to shape its radiation pattern.  LEDs have many advantages over incandescent light sources including low power consumption, long service life, improved physical robustness, smaller size and faster switching. LEDs powerful enough for room lighting are relatively expensive and require more precise current and heat management than compact fluorescent lamps sources of comparable output.
college is place were ever student loves it and enjoy with his friends we meet different kind of people that maybe good or bad
we learn how to behave with people in society
we learn how to respect our elders and parents and teachers
