[China Building Materials Network] Lighting is an important part of TV program production. It is a comprehensive system integrating modern technology and performing arts. The design level, design configuration and application capabilities of the TV lighting system play an important role in the production of the program. At present, with the continuous development of technology, the configuration of studio lighting has been developing in the direction of all-digital, high-definition, multi-functional 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 the 1960s, LED lighting has been hailed as the third revolution in human lighting due to its long life, energy saving, rich color, safety and environmental protection.
In the field of radio and television, the light source currently used in the film and television stage is mainly tungsten halogen lamps and gas discharge lamps, which are characterized by low luminous efficiency, short life, high power consumption, and unstable operation, due to the general power of film and television stage lamps. More than 1000W, other high quality alternative light sources have not been found at home and abroad. In the professional lighting of the film and television stage, the professional lighting equipment used is mostly high-power halogen tungsten light source lamps of 1KW to 18KW. The main issues are:
The halogen light source has a low luminous efficiency: more than 95 of the power consumption is converted into heat energy, resulting in great waste of energy.
Serious thermal pollution: The tungsten halogen light source converts most of the energy into heat while converting electrical energy into visible light, causing huge thermal pollution. In use, it is necessary to take measures to cool down, resulting in repeated waste of electricity and capital.
Poor working environment: At the same time, the tungsten halogen light source is a heat source, which will generate a large amount of infrared radiation. When it is irradiated on the actor, it will produce a strong burning sensation, resulting in a bad working environment and affecting the performance.
High operating cost: professional halogen tungsten light source has a short life span, generally only about 200 hours.
With the further improvement of LED lighting technology, the key technology research of LED lighting professional lighting equipment is solved, and LED TV lighting fixtures of 100W and above are introduced with high efficiency, energy saving, long life and environmental protection technology, replacing the tungsten halogen light source of 1000W or more. The film and television lighting, and through the industrialization of LED film and television stage lighting, phasing out the low-efficiency light source of the film and television stage and the performing arts industry has become the main subject of professional and technical personnel in the LED lighting industry. The LED light source is used for professional lighting of film and television stage, and has the following outstanding advantages: high luminous efficiency: the luminous efficiency of the LED light source is as high as 100 lm/w, which is 4 to 5 times that of the tungsten halogen light source.
Infrared radiation is extremely low: LEDs are cold light sources, and infrared radiation is extremely low, which significantly improves the environment.
Long life: up to 50,000 hours of life, more than 200 times that of halogen halogen sources.
High safety: LED lamps are solid-state luminous cold light sources, which are safe and reliable to use, and there is no safety hazard of halogen tungsten bulbs breaking.
Green and environmental protection: no pollution during production and use, it is a green light source.
