The emission mechanism of incandescent light is that the energy heats the luminous tungsten filament to glow, after heating in fairly long period, tungsten will be aging and even blows, thus, the life of incandescent bulbs has ended, while the emitting mechanism of light-emitting diode is determined by the diode’s special composition, the diode mainly consists of the PN crystal plate, the electrode and the optical system, when the electrode with a positive bias, the electrons and holes are injected into the P and N regions, when the non-equilibrium minority carrier recombine majority carrier, it will turn excess energy into light energy in the form of photons. The luminescence process includes three parts: the forward bias carrier injection, combined radiation and energy transfer. Thus diode glowing mainly depend on carriers constantly moving, there is no phenomenon of aging and blown,its special luminescence mechanism determines its luminous life that is 5-10 ten thousand hours. |
Li Sida lighting adopts high quality LED semiconductor chip as the light source, LED lighting can be guaranteed within 5-10 ten thousand hours, LED flood light, LED tunnel lights, LED tube and other indoor and outdoor lighting has long been exported and welcomed and praised by consumers ,we have reason to believe that Li Sida lighting www.lead-lighting.com must illuminate every corner of the world with the help of energy-saving LED light in order to make contribution to low-carbon environmental living!
