What are the light sources of the mobile lighting vehicle? What is the difference between them?
Mobile lighting vehicles are widely used. The light sources used in different configuration types of mobile lighting vehicles are different. Common lamps include xenon lamps, mercury lamps, and metal halide lamps. These are gas discharge lamps. Three different types of lamps have different performances. There are certain differences in characteristics. Below, the manufacturer of Storac will take you to learn more about the differences between these three types of lamps.
First of all, through the definition of xenon lamp, mercury lamp and metal halide lamp, roughly distinguish between xenon lamp, mercury lamp and metal halide lamp:
Xenon lamps are generally referred to as HID Xenon Lamps, and the lighting is a cold light source;
Mercury lamps, metal halide lamps are generally referred to as HID Lamps in English, and the lighting is a warm light source;
You can clearly see the xenon lamp and the mercury lamp. One of the differences between the metal halide lamp is that the arc tube of the xenon lamp is filled with xenon gas while the mercury lamp and the metal halide lamp generally do not have xenon gas. Therefore, the price of xenon lamps is generally much higher than that of metal halide lamps and mercury lamps.
Secondly, the xenon lamp can be turned on immediately, not only cold start, but also hot start. Therefore, it can be used as a car headlight. However, the start of the xenon lamp requires a very high pulse voltage, usually 12000V. Therefore, the price of the ballast of the xenon lamp is generally more expensive.
For metal halide lamps and mercury lamps, only cold start, not hot start. In other words, if you turn off the lighted metal halide lamp or mercury lamp, you must wait another 5-10 minutes before lighting it up again. Therefore, they are generally used for commercial lighting such as square lighting and street lighting. For metal halide lamps, only a pulse voltage of 3000-4000V can be started. For mercury lamps, a trigger is not required, and a voltage of 220v can be started.
Finally, let’s talk about the difference between a mercury lamp and a metal halide lamp. The difference between the two is that the metal halide lamp has pills, while the mercury lamp does not. Therefore, the light efficiency of the metal halide lamp is high, and there are many color temperatures, from 3000k to 20000k, but the mercury lamp can only be made with one color temperature, about 4000k, because the arc tube has no pills, but the common point of the three is All belong to gas discharge lamps.
