Home lighting design: light source classification (two)

Light source three: fluorescent lamp

The principle of fluorescent lamp is to use low pressure mercury vapor in the discharge process of ultraviolet radiation, so that the fluorescent powder to emit visible light, belonging to low pressure arc discharge light source. The color temperature of the light source is rich, so that the full color temperature can be achieved.

Performance: light efficiency is more than three times the incandescent lamp, and more energy saving, longer life

Light source four: metal halide lamp

The metal halide lamp is the third generation light source which is added on the basis of high pressure mercury lamp. The utility model has the advantages of high luminous efficiency, good color rendering performance and long service life. The utility model is a novel energy-saving light source which is close to the daylight color.

Performance: light efficiency is 3-4 times of incandescent lamp.

Light source five: LED lamp

LED is actually a light-emitting diode, a solid-state semiconductor device, can be directly converted into a new light source of green light, the core of which is a semiconductor chip. LED has the advantages of small size, light weight, low power consumption and so on. It is the best choice to replace the traditional light source.

Performance: more than 2-5 times higher than the traditional light source in the life and light efficiency.
