The working principle of the energy-saving lamp is to heat the lamp filament through the ballast. At about 1160K temperature, the filament starts to emit electrons (because some electron powder is coated on the filament), and the electrons collide with the argon atoms to produce inelastic collisions, and the argon atoms. After the collision, it obtains energy and then hits the mercury atom. The mercury atom undergoes ionization after absorbing the energy, and emits ultraviolet rays of 253.7nm. The ultraviolet rays excite the phosphor to emit light. Because the temperature of the filament when the fluorescent lamp is working about 1160K, which is 2200K higher than that of the incandescent lamp. -2700K is much lower, so its life is also greatly improved, reaching more than 5000 hours. Because it does not have the current heating effect like incandescent lamps, the energy conversion efficiency of phosphors is also very high, reaching more than 60 lumens per watt.

Whether the LED lamp is stable or not, the quality is most closely related to the heat dissipation capacity of the lamp body itself. At present, the heat dissipation of high-brightness LED lamps on the market usually adopts natural heat dissipation, and the effect is not ideal. If the heat dissipation is not ideal, the life of the lamp itself will also be affected.
