Market situation and development potential of domestic LED film and TV stage lamps

LED with remarkable characteristics of energy saving, environmental protection, long life has been from the original mobile phone, traffic signal, display and other special lighting field, started to enter the large size LCD backlight, car headlights, street lamps and other lighting, the use of public infrastructure and application market agriculture, medical, television and many other emerging stage also began to start. One of the LED film and stage lighting because of its great potential and broad market space for energy saving and emission reduction has attracted a number of manufacturers to invest in the development and promotion.

First, the development and application of domestic and international LED film stage lighting has started

At present, the light source used in the stage lighting is mainly halogen tungsten lamp and gas discharge lamp (including low voltage discharge fluorescent lamp and high intensity gas discharge metal halide lamp, xenon lamp). Although the light source can meet the needs of film and television lighting, but there are some disadvantages such as low light efficiency, short life, large power consumption, unstable work, etc.. With the development of high power LED technology is deepening, the international general LED products used in functional lighting, has achieved a breakthrough, making the film stage lighting showing the development trend of the LED as the main light source. In foreign television studio, theater, gymnasium and other professional lighting field has a high power LED lamp, lighting the sky line lights, soft lights lighting products etc.. It is understood that the stage of functional film of high power LED lamps developed by PHILPS news studio has been used in the Holland TV news studio, British television, but because the product is single, is also not very broad.

Now the domestic and international film and television stage lighting manufacturers in the new situation of energy saving and environmental protection, has begun to focus on the emerging potential applications. At present, in addition to a number of foreign manufacturers of lamps and lanterns in the efforts to develop a variety of new types of LED lighting suitable for film and television stage lighting products, there have been a number of domestic active development and promotion of LED film and television dance lamp manufacturers. In November 5, 2008 the opening of the seventeenth session of Beijing International Radio, film and television equipment exhibition (BIRTV2008), Guangzhou has Yajiang Photoelectric Equipment Co. Ltd., Beijing jinshiweishi Polytron Technologies Inc, Guangzhou Shenglong lighting equipment Co. Ltd. and other manufacturers exhibited a LED film developed stage lighting.

Two, LED film and television stage lighting will be an important force in energy conservation and environmental protection

In July 23rd this year, Premier Wen Jiabao at the State Council executive meeting pointed out: "we should pay attention to lighting electricity saving. Increase the promotion of efficient lighting products. "For a long time, lighting power consumption has accounted for a large proportion of all countries in the total power generation, lighting power consumption in Europe and the United States and other western developed countries accounted for about 20% of the total generating capacity, China's lighting power consumption accounted for about 13% of the country's total generating capacity. 2007 China's total electricity generation of 32559 kwh, that is about 423 billion 300 million kwh for lighting, for the construction of the Three Gorges hydropower project put into operation in the year after generating capacity (84 billion 700 million degrees) about 3.84 times. Thus, energy-saving lighting significant.

According to the data released by the NDRC, China's existing studio, theatre, theatre vanguard, traditional film stage lighting power by small hundreds of watts, most of them are thousands of watts, the power resource consumption is very large. If all of these functional lighting to energy-efficient LED lights, this year alone can save 60 billion kwh, reducing carbon dioxide emissions by 60 million tons. In addition, LED is a cold light source, low calorific value, greatly reducing the performance of the ambient temperature of the venue, so that the air conditioning unit load significantly reduced, there has been a joint energy-saving effect. Therefore, the full use and replacement of LED film stage lighting will make an important contribution to China's energy conservation and emission reduction.

Three, LED film and television stage lighting market potential

With the development of digital TV industry and the development of LED technology in 11th Five-Year, the development of LED technology in the field of Optoelectronics has brought great opportunities for the development of the TV industry. 2007 film and television stage lighting market capacity has reached 2 billion 420 million yuan, in 2008 is expected to reach $2 billion 750 million, an increase of more than 10%.

At present, there are nearly 5000 national television studio, in addition to the stage theater, school hall and many other places of large power consumption nearly 10000. Under normal circumstances, the provincial and municipal television studio equipment update cycle of five years, local stations and other special places to update the cycle of 10 years. That is to say, every 5 years or so all kinds of provincial studio equipment will have a larger replacement, every 10 years or so all kinds of local television equipment will have a larger scale replacement. In addition, cultural and entertainment venues, video equipment rental companies are also changing demand.

Four, LED video stage lights will save users to maintain the use of cost

At present, the use of LED stage lighting stage of the initial installation cost is much higher than the traditional lamps, but the maintenance and use of the cost is much lower than the traditional film and television stage lights. A quartz tungsten halogen bulb of the common thread of the spotlight had a life expectancy of 750 hours, 2000 Watts of power, and LED lamp life up to 50 thousand hours, a LED lamp to achieve the same effect as 200 watts, calculated in accordance with the daily light for 6 hours, the running cost is only about 1/5 of the common thread spotlight. If things go on like this, the cost savings can not be ignored. In addition, because LED is a cold light source, very little heat, but also reduces the cost of air conditioning, which saves a lot of money.
