Application of LED lamps in Digital Studio

【China Building Materials Network] Visual lighting is an important part of TV program production and a comprehensive system integrating modern technology and performing arts. The design level, design configuration and application ability of TV lighting system play an important role in program production. At present, with the continuous development of science and technology, the configuration of studio lights has been developing in the direction of all-digital, high-definition, multifunctional and energy-saving. The application of LED lamps in Digital Studios has also become an inevitable direction. Since the birth of the world's first semiconductor light-emitting diode in 1960s, LED lighting has been praised as the third revolution of human lighting due to its long service life, energy saving, rich colors, safety and environmental protection. In the field of Radio, Film and Television, the light sources currently used in the film and television stage are mainly halogen tungsten lamps and gas discharge lamps, which are characterized by low light efficiency, short service life, large power consumption and unstable work, since the general power of film and television stage lamps is above 1000 W, no other high-quality alternative light sources have been found at home and abroad. In the professional lighting of the film and television stage, the professional lighting equipment used is mostly 1KW to 18KW high-power halogen tungsten light source lamps. The main problem is that the halogen tungsten light source has low luminous efficiency: more than of the electricity consumed is converted into heat energy, resulting in great waste of energy. Serious thermal pollution: halogen tungsten light source converts most of the energy into heat while converting electric energy into visible light, causing huge thermal pollution. Cooling measures need to be taken in use, resulting in repeated waste of electric energy and funds. The working environment is harsh: At the same time, the tungsten halogen light source is a thermal light source, which will generate a large amount of infrared radiation, which will produce a strong burning sensation on the actor, causing a bad working environment and affecting the performance effect. High operating cost: professional halogen tungsten light source has a short service life, generally only about 200 hours. With the further improvement of LED lighting technology, the key technology research of professional lighting equipment for LED film and television stage is solved, with the technical characteristics of high efficiency, energy saving, long service life, environmental protection and so on, LED film and television lighting lamps of 100W and above are introduced to replace film and television lamps of halogen tungsten light source of 1000W and above, and through the industrialization of LED film and television stage lamps and lanterns, the gradual elimination of inefficient light sources in the film and television stage and performing arts industry has become the main topic for professional and technical personnel in the LED lighting industry to tackle key problems. Using LED light source for professional lighting of film and television stage has the following outstanding advantages: the luminous efficiency of LED light source is as high as 100lm/w, which is 4 ~ of halogen tungsten light source ~ 5 times. Extremely low infrared radiation: LED is a cold light source with extremely low infrared radiation, which obviously improves the use environment. Long service life: the service life is 50000 hours, which is more than 200 times that of tungsten halogen light source. High Safety: LED lamps are solid light-emitting cold light sources, which are safe and reliable to use and will not cause potential safety hazards of halogen tungsten bulb breakage. Green environmental protection: it does not produce pollution during production and use, and is a green light source.
