At present, such three-color soft light lamps have been produced by many manufacturers in foreign countries. The lamps with specifications are 440W, 300W, 220W, 120W, 78W. The shapes are rectangular, long, square, round and hexagonal. type. This type of luminaire is not only suitable for use in news studios, but some literary and television programs can use this light, light and soft lighting to create a variety of lighting effects.
According to the survey, most of the foreign TV stations have already used this kind of lighting to light the news announcer. Some famous film factories such as Walter Disney and Paramount also started using this lamp for lighting. There are also many lighting manufacturers in China that are beginning to assemble and manufacture these three-color soft lights. Many TV studios use this type of luminaire to illuminate the announcer.
Most news studios abroad like to use this light for illumination. From the luminaire, they chose the high-quality three-primary soft light that absolutely meets the requirements of the CCD camera, that is, the lamp is 32 or P30, so that the color rendering index can reach 90 or more. The color temperature is around 3200K, no heat radiation, the color temperature can be kept stable during dimming, and cross shadows will not occur when lighting. Ballasts are electronic devices with dimming capabilities. It integrates the preheating circuit of the electrode to protect the electrode. Lamps with operating voltages from 150V to 250V can maintain normal ignition and extend the life of the lamp. Generally, it can be used for 1000-1500 hours.
From the character image, the skin color of foreigners is different. There are white, black, yellow hair, black, blue eyes, blue, and the nose is tall and long. At the same time, when the announcer is hosting the program, the action is also larger, the background is more realistic, and the scene is large. This is a feature of foreigners. According to these characteristics, they use the three primary color soft light to illuminate the light, which not only can make up for some defects of the face of the character, but also increase the beauty of the figure. Moreover, the lamp is equipped with a soft plate and a grille (also called a thick plate). Close-in luminaires are safe to place anywhere in the background, and you can create light effects at will. So the light that comes out is everything that is natural and intimate. Of course, they don't pay much attention to the eyes, because this kind of light shines on the eyes of the characters, reflecting the long strips of light. Only by adding a little virtual light to the lower part of the figure can the eyes look good.
China's lighting manufacturing, due to certain technologies and materials, such as lamps, ballasts and grilles, can not fully reach the advanced level of foreign countries. Only imported parts can be assembled by themselves to meet the lighting requirements. China has assembled an average of more than 5,000 yuan per lamp. And the import of such lamps, each at least 3,000 yuan. In this way, most TV stations can afford such lamps. However, because some lamps are not qualified enough to meet the requirements, they cause a lot of troubles in use. In addition, some TV stations do not have a good grasp of the use of the lamps. The images are not color temperature is not correct, or it is not clear. There is no layering. For example, some of the luminaire reflection systems do not concentrate light, and there is no visor. Originally, such fluorescent lamps are characterized by slow-scattering luminescence, which must change the habit of lighting and adapt to this feature. In this way, when lighting, a light is used as the main light, the brightness is not enough. With two light lines falling on the character, it will produce double shadow, virtual light, and even more ugly. There are also lamps. If you use a lamp with a lower color temperature, such as type 830 or type 31, because the color temperature is low, it is easy to make the face of the person reddish, especially the lips, the lipstick is too thick, and the image is red. It feels more fresh. This is due to the fact that the lamp of the new three-primary soft-light lamp is sensitive to red, which can occur if the lamp of normal color temperature is not used. Although the CCTV news studio used imported lamps, but because of the 31-type lamps, the color temperature is low, which once made some of the announcers' lips red, especially those who have long-term contact lenses, immediately contacted with such light, eye circles It will also turn red. Therefore, from the long-term use of the experience, the announcer should pay attention to the shallowness of the makeup should not be deep, should be thin and not thick. Especially lipstick, it is better to use brown. Coupled with the appropriate choice of lamps, there will be no such problems.
CCTV is currently using imported three-color soft light fixtures for the news announcer. At the beginning, it is not fully understood the characteristics of such lamps, and there are certain problems in the selection of lamps and lighting. For example, the lamp is also equipped with a type 31 lamp. Since the color rendering index does not fully meet the requirements, the type 31 lamp produces some redness. Now it is replaced with a 32-type lamp. The color temperature is relatively normal, and the color reproduction is also better.
On the cloth, the light that the Americans gave to the cloth began to hang the light according to the circular cloth method. Overall, the announcer's image is still clear, which is determined by the three primary color soft light lines, because the light it emits is very uniform and delicate, and can provide the TV viewer's eyes with the full real effect seen on the spot. The broadcaster did not feel dazzled at all, and naturally played their expertise, just as a moderator said, "This kind of light shines on us, very comfortable, without the kind of strong light interference, just like at home. In an extremely comfortable environment, free to play our expressions."
