(1) The light-emitting principle of energy-saving lamps: the lamp filament is heated by the ballast. When the temperature is about 1160k, the filament begins to emit electrons (because some electron powder is coated on the filament), and the electrons collide with the argon atoms to produce inelasticity In collision, the argon atom gains energy after the collision and then hits the mercury atom. The mercury atom undergoes ionization after absorbing the energy and emits 253.7nm ultraviolet light, which excites the phosphor to emit light.
(2) The light-emitting principle of LED lights: LED lights rely on light-emitting diodes to convert electrical energy into light energy. LED is basically a small LED lamp bead encapsulated in epoxy resin, so it is very small and very light. . LED power consumption is very low, generally speaking, the working voltage of LED is 2-3.6V. The working current is 0.02-0.03A. This means: it consumes no more than 0.1W of electricity. Under the right current and voltage, the service life of LED can reach 100,000 hours.
