What's the difference between a metal halide lamp and a high pressure sodium lamp? Which light effect will be better?
Today's general lighting techniques are basically divided into two categories: incandescent and discharge lamps. Such as the use of incandescent lamp, Home Furnishing bulb, is light by heating a tungsten wire; discharge lamps, such as fluorescent lamps, high pressure sodium lamp, high pressure mercury lamp and metal halide lamp, is heated by arc arc tube gas and metal halide light to evaporate and expand pill.
High pressure gas discharge lamp used in three categories: high pressure mercury lamp, high pressure sodium lamp, metal halide lamp, high pressure mercury lamp does not belong to the basic principle of metal halide lamp, metal halide lamp is a variety of metal halide arc added to the high-pressure mercury lamp tube, the light emitting
Metal halide lamp belongs to the high-pressure gas discharge lamp, it will be a highly efficient light, because the metal halide pill in participating in the whole emission process, most of the energy is converted into visible light, only a small part of the energy is converted into heat, resulting in high light efficiency. The metal halide lamp is the newest member of the discharge lamp family. It has replaced incandescent lamp, high pressure sodium lamp and high pressure mercury lamp in many fields. The main advantage of the metal halide lamp is its small size, a 100 watt metal halide lamp with an arc of only one inch, and can be mounted in a very small outer tube. In addition, the demand for energy from the metal halide lamp is obviously smaller than that of other lamps, so the emission of waste gas and waste residue in the process of power generation is greatly reduced, and it is worthy of being called an environmentally-friendly product.
Comfort and a white light dark yellow light high-pressure sodium lamp and high-pressure mercury lamp emits blue light emitted by a halogen lamp, the comfort of pure white light favored by the majority of industrial sites and commercial establishments, it can make the darkroom or night scenery as the sun shining like bright colors.
