The difference between halogen lamp and metal halide lamp

In 1879, Edison invented the first incandescent lamp (carbon wire incandescent lamp) and began the first human revolution in lighting source technology. Incandescent lamps have a short life span, low halogen lighting, but high color rendering.

The second-generation illumination source is a halogen lamp that emits light at a much higher intensity than incandescent lamps, while reducing energy consumption by about a third.

The metal halide lamp is named after the metal halide is filled in the bulb. The basic structure and the principle of light emission are similar to those of the fluorescent tube. The difference is that the arc discharge lamp generates high heat, and the metal halide sublimates into vapor, which directly emits visible light and saves energy. From % to 90%, it is a third generation lighting source.

Metal halide lamp is the third generation of green lighting source in the world after incandescent lamp and halogen lamp. It has the advantages of high luminous efficiency, good color rendering and long service life. It is not only the first choice for high-end cars, rear projection TVs and other light sources. It can also be widely used in military, expedition, underwater operations, field search and rescue and other fields. Compared with ordinary incandescent lamps, metal halide lamps have amazing energy-saving effects and huge market space. At present, metal halide lamps are developing rapidly in developed countries in Europe and America, with a penetration rate of nearly 40%. However, among the 8 billion bulbs produced in China last year, the proportion of metal halide lamps was less than 2%. Due to the lower power, the higher the technical requirements, the current production of metal halide lamps below 50W in China is still blank.
