What is the light source of the multifunctional mobile lighting vehicle? what's the difference between them
Multifunctional mobile lighting vehicles are widely used at present, and the light sources used in different configuration types of mobile lighting groups are different. Common lamps include xenon lamps, mercury lamps and metal halide lamps. These are gas discharge lamps and three different lamps. There are some differences in performance characteristics.
Xenon lights can be turned on instantly, 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, ballasts for xenon lamps are usually more expensive.
For metal halide lamps and mercury lamps, only cold start, not hot start. In other words, if you turn off the illuminating metal halide or mercury lamp, you have to wait 5-10 minutes before lighting it up again. Therefore, they are often used in commercial lighting, such as square lighting and street lighting.

For metal halide lamps, only 3000-4000V pulse voltage can be started. For mercury lamps, no trigger is required and 220v can be activated.
Let's take a look at the difference between mercury lamps and metal halide lamps. The difference between the two is that metal halide lamps have a pill, while mercury lamps do not. Therefore, metal halide lamps have high light efficiency and many color temperatures, from 3000k to 20000k, but mercury lamps 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 that they all belong to gas discharge lamp.
The above is the usage of the light source of the multifunctional mobile lighting vehicle. Different light sources are suitable for different scenes. Therefore, it is necessary to distinguish clearly when purchasing, so as to avoid poor use effect due to improper selection.
