Classification of spotlight
1, metal halide spotlight: The luminous efficiency of its light source is above 80 lumens/watt, so its brightness is higher than that of tungsten halide spotlight and its range is far. HMI2500W spotlights can reach 50 meters and the price is moderate. It takes more than 3 minutes for the light bulb to stabilize after starting.
2, halogen tungsten lamp spotlight: its characteristics are simple structure, no ballast, easy to use, electrified, dimmable, brightness from 0? 100 stepless adjustable, cheap, the disadvantage is low brightness. 2KW halogen tungsten lamp spotlight can only be used within 25m.
3. Xenon spotlight: With the increasing demand of the audience for the artistic level of the program, the performance scene is getting bigger and bigger. Xenon spotlight is favored by users for its long range, high brightness and good light color.
For example, the spotlight of a 3KW xenon lamp is at a distance of 120m, and the spot diameter is 3. 7 meters, the illumination reaches 4700 lux, which is very important to highlight the subject in the bright background, especially in the stadium or other large-scale performance venues, where the long-distance light chasing exceeds 100 meters, and only the xenon spotlight can undertake such an important task. In addition, the xenon spotlight has an important advantage, that is, the color temperature and spectrum remain unchanged during the dimming process, which is incomparable to tungsten halogen spotlight and metal halide spotlight. application area
1, Wedding Application: How many spotlights will be used at the scene? Personally, I think it is better to have more than two. Because the spotlight is a cold light source, the beam is concentrated and will not scatter. The spotlight shines on the object, and the contrast between the illuminated surface and the backlight surface is great, so there is no way to fill the light at the candlelight wedding scene. Therefore, when a spotlight shines on the couple's face, it will cause yin and yang faces. When the couple takes the happiness channel, they will be backlit half the time, and all of them will be sidelights in the ceremony, which will greatly affect the image of the couple. If two or more spotlights are lit at the same time, the above consequences will not be caused by the supplementary light source. Spotlight belongs to the high-end equipment in the wedding scene, with high cost, large volume, heavy weight and complicated operation.
So someone must look after it. Handle with care when transporting. The spotlight has a special turnover box. The bracket must be firm and stable, and two people must cooperate to complete the lighting. After electrifying, turn on the switch, and wait for the self-check of the machine for about 5-8 seconds before operating. 2. Stage application: In almost every dance performance, spotlight is widely used to reflect and achieve some artistic effect. Spotlight can highlight the main characters, shape different types of characters, show the changes of drama plot and characters' feelings, and create a stage atmosphere. Therefore, the choreographer and lighting designer of dance drama (including general dance) regard the use of spotlight as one of the indispensable and important means in their own creation. In the design of dance drama, the following purposes are achieved by using the spotlight: 1, the creation of environmental atmosphere; 2. Illuminate the characters and shape the image; 3. Pay attention to performance and highlight key points; 4. The performance and development of the plot.
