Realization of warming in LED lighting
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2017, Vol 12, Issue 6
Abstract
LEDs are semi-conductive p-n diodes emitting light. When current flows in the conduction direction in a p-n junction, the electrons and holes are confronted with each other and recombine in the junction where the p and n semiconductors are combined. The energy that the electrons lose from the free state to the connected state is given either as heat or light to the semiconductor material. In solid-state lighting, 80% of the energy, which is usually caused by photon activity, is heat and 20% is light. In this report, the light and heat emission of the LEDs are investigated.
