How about a metal halide lamp? Factors affecting the life of metal halide lamps
Metal halide lamps are also metal halide lamps. I believe you will not be unfamiliar with metal halide lamps. Metal halide lamps are the third-generation light sources made by adding various metal halides on the basis of high-pressure mercury lamps. They are widely used in indoor stadiums, exhibition centers, large shopping malls, industrial plants, street squares, stations, docks and other places. illumination. So, what about the metal halide lamp? What are the influencing factors of the life of metal halide lamps? Don't worry, BENWEI will explain it to you, let's take a look.
How about a metal halide lamp?
1. Advantages and disadvantages of metal halide lamps
The biggest advantage of the metal halide lamp is that the luminous efficiency is extremely high, the luminous efficiency is as high as 80-90Lm/W, and the heat is low when it emits light normally, so it is a cold light source. Since the spectrum of the metal halide lamp is superimposed on the continuous spectrum based on the dense linear spectrum, the color rendering index is particularly high, that is, the color reduction is particularly good, up to 90%. In addition, the color temperature of metal halide lamps is high, reaching 5000～6000K, and the special projector lamp can reach 7000～20,000K. Under the same brightness conditions, the higher the color temperature, the brighter the human eye feels. The metal halide lamp has a relatively short life due to its high brightness and small size. Due to the limitation of materials and technology, the domestic metal halide lamp has a life span of 8,000 hours.
2. Characteristics of metal halide lamps
With the continuous improvement of technology and craftsmanship, the led metal halide lamp has an excellent comfortable and efficient lighting environment, and also has a significant energy-saving effect during use, making it a leader in many types of lamps. The high luminous efficiency of the led metal halide lamp is the fundamental condition for energy saving. The luminous efficiency is as high as 106 lumens/watt, and it has an excellent luminous maintenance rate. The average life of the led metal halide lamp can be as high as 20,000 hours, which effectively reduces the replacement and maintenance costs of the lamp. . Due to the increasing market demand for LED metal halide lamps, there are many specifications of LED metal halide lamps. The diameter of the more common LED metal halide lamps is between 38-182mm.
Factors affecting the life of metal halide lamps
1. Driving power (ballast), the metal halide light source needs a very high instant voltage (characteristic of the metal halide light source) when it is lit. The instant starting voltage is generally above 3000V. The current mains voltage is only 220V, so The smooth start of the metal halide lamp can be realized through an electronic ballast, and the metal halide lamp will not light up without a ballast. It is best to be equipped with a constant current design d electronic ballast (energy saving, prolong the life of the light source and the light source will not flicker).
2. The manufacturing process, the manufacturing process of different manufacturers or the same manufacturer, may cause the electrical parameters of the bulb to appear discrete. Mainly reflected in tube pressure, tube flow and trace element difference of metal halide pellets, color temperature error, of which lamp tube current is the main factor.
The above is the explanation of the knowledge of the metal halide lamp and the factors affecting the life of the metal halide lamp. The content is for your reference only, and I hope it can be helpful to you.
