Research Group: Wang Jingchi, Gu Genjie, Xi Gangma Road, Bai Wenguo, Li Jian, Zhang Chong, Mu Huaiqi
In early December in Beijing, winter has just arrived, perhaps because of the snow after the sunny sky feels a bit cold. Members of the Research Group of the China Film and Television Television Lighting Professional Committee visited the An Hengli (International) Co., Ltd. (An Hengli), Beijing Starlight Film and Television Equipment Technology Co., Ltd. (Starlight), ARRI (China) with eagerness. ) company (Alai).
I. Exploring An Hengli
Founded in Hong Kong in 1982, An Hengli is an engineering company providing professional video and audio and stage lighting services. After more than 30 years of development, the company has become a well-known professional equipment supplier in mainland China, Hong Kong and Macao. It is one of the most authoritative and largest agents in the domestic stage lighting industry. They continue to provide the industry with the latest high-quality lighting and audio equipment and high-end technology. The company acts as a stage lighting and LED screen with independent intellectual property rights. The long-term partners in the field of lighting include Italian ClayPaky, German MA, Australian SA, Italian SPOTLIGHT, French AYRTON, British PULSAR, Swedish WDMX and other international first-line brands.
In recent years, the lighting products represented by An Hengli have been in a leading position. The Sharpy Elf Beam Light, launched in 2011, enriches the composition of the stage film and television with the latest light source and narrowest beam, emphasizing the impact of visual images and expanding the development space of film and television lighting design. Affected by the luminaire, domestic manufacturers have successively produced a small Beam that resembles a light source, and quickly has a market. In the following years, ClayPaky has launched new products, such as Sharpy Wash in 2013 and EYE Bee Eye in 2014. This year, the launch of the SCENIUS pattern computer light is of great significance to the era when the current TV variety show lighting is dominated by computer lights.
SCENIUS pattern computer light
After years of development, computer lights using gas discharge sources have reached a very high level. Nowadays, Baiqi returns his attention to the most primitive needs. He wants the lighting designer to think about it, pursue higher quality light quality, higher output brightness and higher pursuit of cost performance. SCENIUS can be said to be the top pattern computer light in the Baqi lamps.
SCENIUS adopts OSRAM's new 1400W/1200W light source, and is equipped with Baiqi's specially designed optical system. It uses 142mm large-diameter lens and 7x optical zoom. The zoom range is 8~55 degrees, which is brighter than the previous ALPHA SPOT 1500 computer light. ~30%.
High light quality and rich visual effects are the biggest features of SCENIUS unlike other lamps. The color temperature of the lamp source is 6000K, the CRI of the light source is close to 95 (the metal halide source is difficult to achieve such a high index in the past), and a set of accurate CTO is configured to adjust the color temperature very linearly to achieve the halogen lamp. The degree of matching. CMY mixed color filter color filter can be used to obtain a very wide color gamut, and then used in conjunction with the CTO system to make the light output color vivid, full and pure. The luminaire is equipped with 12 glass pattern pieces, 2 pattern wheels, a rotatable polygon mirror and a replaceable glass animation effect board. All patterns can be independently changed and rotated, and auto focus function is also available. These configurations make SCENIUS very visually pleasing.
The other luminaires that the experts saw were absolutely shocking. This is the secret member of the Baichi Project series, the spheriscan scanning computer light. Its biggest feature is that it can rotate in all directions. After many years of gold scanning computer lamp family became legendary, Bach has invested huge research and development technology to re-explain and perfect the concept of scanning lights.
This used to be a product that many lighting designers dreamed of. ClayPaky, a well-known brand in the lighting industry, has upgraded its lens-scanning computer lights, which were once proud of the lighting designers and have almost forgotten. It overcomes the shortcomings of the original scanning lamp, which is bulky and cumbersome, and solves the various drawbacks of the original scanning computer lamp, and rejuvenates the old-fashioned computer lamp. Spheriscan has improved the scanning speed of the luminaire, and can rotate 360 ​​degrees without interruption. It uses a new concept in its development, and applies new technology. The small and flexible body can not only play an advantage in the stage lighting, but also play a great role in the stage art.
The spheriscan scanning scanner has a high scanning speed of up to 250 laps per minute, which is four times that of old scanning fixtures and eight times that of moving headlights. The horizontal axis can be completely endlessly rotated, 360 degrees without limit, and its positioning accuracy is also convincing.

The luminaire uses the same new Osram 1200W light source as the Scenius. Through the three primary color CMY blending, you can create a wide color gamut with vivid, subtle, soft colors and precise color tones. There are also 6 special color patches on the lamp color wheel. The luminaire is equipped with 6 rotatable pattern pieces, 8 fixed pattern pieces, and a self-rotating prism can be superimposed on the pattern. 1 high-precision aperture, 1 variable range soft lens. The luminaire can be zoomed at a high speed in the range of 13 to 34 degrees. This is larger than the zoom range of all previous scanner lights. The special transparent lampshade has an IP54 rating and can also be embedded in the stage floor, leaving only a transparent lamp head. This kind of beauty design makes the visual creations refreshing, the scanning lens is removed, and it can also be used as a simple direct-injection pattern computer light.
Experts also saw the newly developed MagicDot-R series and IntelliPix-R series of lamps from Ayrton manufacturers. Although they are small lamps, they are arranged in different combinations to create a fascinating and pleasing lighting effect. In addition, the small moving lights of the two LED light sources can create a lot of stage effects through a certain number of combinations, and may also be an innovative way in the future stage.
These new luminaires, these new ideas, and these new technologies are important support for lighting designers, lighting teaching teams, and performance creation groups. It can be very useful to directly influence the technical solution ability and means of artistic creation. Understanding the mastery of new technology is equivalent to winning a new artistic creation space.
Second, visit the starlight
On the afternoon of December 3, the research team visited Starlight.
Beijing Xingguang is not only a leading enterprise in the field of domestic stage film and television lighting, but also a leading unit leading the development of the industry. In recent years, the company has achieved remarkable results in both R&D and production of film and television equipment and stage lighting, processing and commissioning of stage technology equipment. Since 2009, the company has cooperated with professional committees and CCTV to carry out the "Application Research of LED Lighting Fixtures in TV Studios", which has played a positive role in promoting the development of LED stage lighting. The research also won the second prize of Science and Technology Progress (soft science) of the State Administration of Radio, Film and Television. In the past few years, the company's LED lighting fixtures in the studio and theater have achieved great success. He has made great contributions to the energy saving and emission reduction of stage film and television lighting. He has been commended by the Beijing Municipal Development and Reform Commission, the Beijing Municipal Science and Technology Commission and the Beijing Municipal Bureau of Culture. The construction of the Starlight Film and Television Park has greatly improved the level of program production in China's TV industry, shortening the cycle and improving the quality. Recently, Beijing Xingguang Film and Television Equipment Technology Co., Ltd. (Starlight Film and Television) officially landed on the New Third Board stock exchange market, which is the best recognition of Starlight. Starlight Film will take this opportunity to further standardize and improve the governance structure, improve its core competitiveness, and use the capital market to play a greater role in promoting the development of China and the world cultural equipment industry.
In the small studio in the Starlight Film and Television Park, the chief engineer of Starlight Film and Television, He Ping, gave a detailed demonstration of the newly developed LED stage lamps, including 6-color LED imaging lights, threaded spotlights, flat-convex spotlights, and skylights. Experts feel that these lamps are very creative and have good light quality, which can be applied to film and television. Everyone saw that the lighting effect of the LED skylight was very good, and the uniformity of the imaging light spot reached a very high level. The imaging lamp used the mechanical arm to solve the short board in the studio, and it will definitely help to enter the large and medium-sized studio. . At present, the imaging lamp has no moving arm, and it is a short board that enters the studio. The spot quality of the spotlight is also remarkable. These luminaires support the HSIC control mode, which allows for continuous changes in color and saturation, and continuous changes in color temperature in white mode. The expert group tested the light output of the lamp on site, in which the low color temperature mode white light measured color temperature 3268K, the color rendering index Ra was 96, R9 was 98, the high color temperature mode white light measured color temperature 5570K, the color rendering index Ra was 94, and the R9 was 92. It can be seen that LED lamps can achieve ideal lighting effects by using white light produced by mixing a plurality of colors, especially the R9 value far exceeds the expectations of the expert team.
Starlight Thread Spotlight
According to the introduction of the general manager, achieving such an effect is inseparable from the LED accurate color mixing algorithm used in the lighting control system. The company has made a lot of efforts in researching and exploring LED color mixing algorithms. With 6 color LED combinations, the color gamut of the output color of the lamp has a certain expansion compared with the 4-color lamp, and the white color rendering index and brightness of the mixed white are obviously improved. In addition, the use of multi-color source mixing also helps to calibrate the color temperature drift caused by the junction temperature change of the LED source in real time.
Another LED flat-panel soft light is displayed in a mixture of 4 colors. The color temperature is continuously adjustable from 3000 to 6000K, and the maximum power in the whole color temperature range is constant at around 100W, and the color rendering index is above 94, especially The lighting performance reached 100lm/w, and the experts questioned it and conducted on-site testing and estimation. It has been estimated that such high light efficiency data has been basically recognized by everyone.
