Incandescent luminescence refers to visible electric radiation that is generated by the excitation of atoms. Incandescent lamps use the principle of incandescent illumination to allow current to pass through the tungsten wire in the vacuum, causing the tungsten filament to warm up to incandescence and emit visible light. The color temperature of ordinary incandescent lamps is 2800K, which is yellower than natural light and looks warm. The advantages and disadvantages of incandescent lamps: low cost, easy to use and install. Suitable for frequent opening, the effect of the off on the performance and life of the lamp is very low.
Advantages and disadvantages of incandescent lamps:
Short life and low luminous efficacy. Incandescent lamps emit less than 10% of the visible light, and most of the energy is converted to infrared radiation, producing a large amount of heat. In addition, the ultraviolet radiation emitted by incandescent lamps is also relatively high, causing fading of the illuminated articles.
