Working principle of energy saving lamp

- Dec 07, 2017 -

Human life in addition to water, air, food necessities, light has been affecting people's work and rest, has been the sunrise, sunset and the life. Until 1879 Edison invented the light bulb (incandescent lamp), its principle is: when the lamp access circuit, the current flow through the heat effect of the filament, so that the incandescent light emitting continuous visible and infrared, this phenomenon in the filament temperature rise to 700K can be detected, due to the work of the filament temperature is very high, Most of the energy is wasted in the form of infrared radiation, and because the filament temperature is very high and evaporation is very fast, the life expectancy is greatly shortened, about 2,200 hours, and the light effect is around each tile (Lm). Before lighting system only pay attention to quantity, and today has been gradually to exquisite, pay attention to provincial energy effect. Due to the wide use of lighting technology and lighting equipment, people's living standard is generally improved, the demand for lighting equipments is increasing rapidly, and the power consumption is enlarged, so the development of high efficiency and high-quality lighting equipment is paid attention to.
