Incandescent lamp
The incandescent lamp is made by passing current through the tungsten wire in the lamp, heating the tungsten wire to the incandescent state, and the light is yellow. Under the incandescent light, the object has no color difference. The incandescent lamp has a simple structure, is inexpensive, is easy to install, and is quick to start, but has low efficiency, consumes a lot of electricity, and has a short life.
2. Fluorescent light
The fluorescent lamp adopts a voltage applied to both ends of the lamp tube to ionize the inert gas in the lamp tube to generate an arc discharge, and the lamp tube starts to illuminate. Fluorescent lamps have low power, high efficiency, no glare, no shadow, and long life, but the installation is more complicated than incandescent lamps, and the life is related to the number of times of opening. The color difference is not suitable for precise working lighting, and the price is better than incandescent lamps. high.
3. High efficiency energy saving lamp
The energy-efficient lamp is a new energy source recently introduced. It is also a light source for gas discharge, which is more efficient and more energy efficient than fluorescent lamps. However, like the fluorescent lamp, the color rendering is poor, and the light has a gradually brightening process after starting, and the price is more expensive than the fluorescent lamp.
