The expert group and the company's production and technical personnel conducted in-depth exchanges and discussions on the manufacturing R&D and practical application of conventional lamps, computer lights, LED lights, studio mechanical hanging equipment, lighting consoles, LED screens and other equipment.

The main purpose of the survey is to discuss the latest technology and application of stage film and television lighting with various production companies, to explore the future development direction of lighting and lighting technology, to strengthen the communication and interaction between lighting design and production professionals and production enterprises, and jointly promote the improvement of the comprehensive level of lighting production. And to promote the development of China's lighting industry. Through exchanges and investigations, the expert group formed four research reports on "Guangzhou Lighting Research Report 2017", "Jiangsu and Zhejiang Lighting Research Report 2017", "2017 Beijing Light Research Report" and "2017 Hunan Lighting Research Report". Based on these four reports, this analysis report was formed.

First, the regular light

Commonly used conventional lamps are mainly spotlights, floodlights, imaging lights, Par lights, chasing lights, etc., which are generally not equipped with electric rocker arms for general lighting. But "conventional" does not mean old or backward, and the pace of progress and improvement has not stopped. This survey found that conventional lamps have made great progress in terms of brightness, color temperature, color, color rendering index, heat dissipation method, refresh rate, and manufacturing process.

1, the light efficiency of the lamp is improved

In the survey, I saw a lot of large-light, high-efficiency lamps.

At Spark, we were pleasantly surprised to see Philips' Fresnel spotlights, which were developed for film and television studios to replace traditional halogen-tungsten light sources. They took a unique middle path from the dense array of COB and distributed array combinations. With a slightly dispersed chip array, a variety of chips are combined into a light source, the heat dissipation system is good, the spot is uniform, the light exit angle is flexible, and the total luminous flux of the output reaches 18,600 lm.

Philips LED Fresnel Spotlight

Starlight's LED bee-eye flat-panel soft light uses high light efficiency, high color rendering surface mount (SMD) LED as a light-emitting element, and the light effect reaches 100lm/w or more. The bee-type compound eye array soft light plate is composed of a 2mm diameter aspherical condensing mirror to form a microlens array. It can concentrate light and reduce glare while concentrating light, so that the beam angle of the luminaire is concentrated from 120 degrees of SMD. By 70 degrees, the stray light is greatly reduced, and the center illumination is increased by more than 50% compared with the ordinary soft plate.

2, color temperature control is strengthened

The current performance, whether it is a TV party or a stage performance, basically requires video recording. This requires the concept of color temperature to be emphasized. Otherwise, it is possible that two types of white light lamps with inconsistent color temperature are projected onto an object, and the color shift of the television picture appears.

LED light source has its unique advantages in color temperature. A lamp type can be configured with different color temperatures. There are 3200K low color temperature lamps and 5600K high color temperature lamps to meet the needs of different environments.

In the survey, we found that every company that does conventional lighting has done a good job on the color temperature of LED lamps. Brilliance's TG-LBRD1 LED flat light, Yajiang's SS827SW HD imaging light, color temperature 3200K and 5600K optional. Some lamps have the function of adjustable color temperature. The color temperature of Brilliance TG-LBRDT1 LED flat light can be continuously adjusted from 3200K to 5600K. Fonda's FDL-J300L thread spotlight, the color temperature can be linearly adjusted between 2800K~10000K. Minghe's 324PR-7 color flat-panel soft light, the color temperature can be continuously adjusted from 3200K to 5600K, and its color difference is almost unchanged during linear dimming from 0 to 100%. ETC's luminaire color temperature control has a spectral automatic corresponding adjustment function. The Eos series console software refines the color control to control the lights of each color. Under the premise of locking an output color temperature, the output of the lamp bead can be changed to reduce the proportion of an unwanted color in the color composition. The console automatically adjusts the output ratio of the other color bead to ensure that the output color temperature does not change.

The color temperature can be adjusted to meet the different needs of lighting designers for different color temperatures. Moreover, it can be used for one lamp, saving money for customers and allowing the lamps to play as many functions as possible in different performances.

3, color control is strengthened

In this survey, we found that many companies have taken a lot of effort to control color.

Yajiang uses color light to mix into white light, and uses the color management system to solve the problems of color mixture uniformity, white light quality, and ease of operation. Using the full spectrum series of lamps of the color management system, the white color temperature is adjustable from 2700K to 6500K, the general color rendering index Ra is above 90, and the CQS value is above 85. In order to maintain the quality of white light in the process of white light dimming, it is necessary to form white light, and each color light is smoothly dimmed and changed with a completely uniform dimming curve. In poor quality LED lamps, when the brightness is dark, its color will also change. In this investigation, Yajiang presented a fine dimming curve of red, green and blue colors measured by a third party.

Dexter's WS-8248 200W LED canopy lamp adopts a new optical design, realizes the effect of traditional asymmetric skylight with LED, the spot is soft and uniform, and the color is uniform; 8-color LED light source (red, green, blue, cyan, dark blue, Amber, cool white, warm white), more colorful, in line with the needs of professional users.

德晟's WS-8248 200W LED canopy

Fonda's FDL-J300L-C spotlight uses a 7-color LED array color system (red, orange red, amber, green, cyan, blue, dark blue). The spectral distribution is more continuous and closer to natural light. Compare 3 colors (red, green, blue) or 4 colors (red, green, blue, white) or 5 colors (red, green, blue, amber, white) to richer colors, wider color gamut, and more colors to choose from. many. The 7-color system can mix very good white light, the color temperature can be adjusted from 2700K~10000K, but the brightness can be kept almost unchanged.

Minghe's 324PR-7 color flat-panel soft light uses 7 color LEDs as the light source. The specially designed optical system makes the spot more soft and the color mixing effect is good. The optical path design of asymmetric light distribution can better solve the lighting requirements such as the stage skylight area. Using HISC color management system control technology, it can mix a rich standard color, make up for the color mixing defects of the traditional RGB three primary colors, making the color more saturated and vivid.

ETC was one of the first manufacturers to manufacture lamps using color LED light sources. Their color processing technology is in the world's leading position, and color can be obtained according to color paper coding. After several years of research and matching, ETC engineers have produced a complete color system based on the chromatographic xy values ​​of standard color papers of major manufacturers (such as LEE or ROSCO colored paper), without changing the working habits of the lighting engineer. You can easily retrieve the desired color paper number.

ETC's intelligent color management system

In addition to the color mixing function, Alai's ARRI SkyPanel series products can meet the requirements of film and TV shooting through the color mixing management system, which can mix high-quality, high-color white light with excellent temperature of 2800K-10000K. Recently, the company has also developed more than a dozen unique lighting effects for lighting, such as lightning, candlelight, flame, police lights and so on. It is also possible to upgrade the original luminaire control software, and it is possible to control the luminaire to complete various effects without replacing any hardware.

Alai's ARRI SkyPanel

Starlight Video Equipment Technology Co., Ltd. proposes a solution for dynamic compensation of each lamp parameter for the problems of poor light color consistency, low color rendering performance and poor color temperature stability of LED lighting fixtures currently on the market. Based on industrial automation control system, fast spectrum measurement technology and colorimetric data processing technology, the company has developed an online on-line detection and calibration system for LED lamps. Each lamp must be tested for color coordinates, luminous flux, etc. of each LED before leaving the factory. The current curve changes to generate a unique parameter library. The lamp control software performs automatic color mixing calculation and dynamic compensation control according to the parameter library, thereby achieving uniformity of output light.

4, the color rendering index is improved

The color rendering index (CRI) is an important indicator to measure the quality of white light fixtures. Many luminaire manufacturers recognize this and increase their color rendering index as much as possible while increasing the brightness of the luminaire. Of course, the increase in the color rendering index of the light source will also result in a reduction in light efficiency and an increase in cost. Therefore, it is necessary to select a balance point that satisfies both the use requirements and the cost. In this survey, we found that many companies have achieved a color rendering index of more than 90 for conventional lamps.

In Scone, we saw a Fresnel spotlight that replaces the traditional tungsten halogen source. The various chips are combined to form a light source to produce a very high white color rendering index. The Ra is up to 98 by the hand-held spectrometer on site, and the R9 is also above 90, which is almost the standard of the ideal tungsten halogen source.

Fonda's FDL-J300L-CLED spotlight uses a 7-color LED array color system (red, orange, amber, green, cyan, blue, dark blue). The spectral distribution is more continuous and closer to natural light. In the linear adjustment of color temperature and brightness, a high color rendering index can be maintained.

For LED luminaires, it is not easy to maintain an ideal color rendering index during various dimming processes. If LED luminaires are ready, this will be an ideal luminaire for use as a facelight.

5, the heat dissipation capacity is improved

In addition to indicators such as light efficiency, light quality, and light color, the heat dissipation capability of lamps is also an important consideration. Especially for LED light source lamps, the heat dissipation is related to the stability and longevity of the lamps. In this survey, we learned that many manufacturers have their own unique design for heat dissipation.

Fangda's FDL-J300L series lamps adopt the air-cooling heat-dissipation mode, and the mute effect is good, and the noise is ≤25dB.

Brilliance's third-generation 100W/150W LED spotlight, the cooling system uses a natural cooling mode, no fan, no noise.

Brilliance's third generation 100W/150W LED spotlight

Haoyang's F90 series of film and television lamps use fanless cooling technology.

6, the refresh rate is increased

For general video recording, the refresh frequency requirement of the luminaire is not very high, but for high-definition video slow-motion playback, the refresh frequency is very important. Slow-motion playback, sometimes it is found that there are flicker, stepping, etc., because the refresh rate of the light is too low.

In order to solve this problem, many manufacturers have carried out many tests, and through unremitting efforts, constantly improve the refresh rate of the lamps. For example, Desheng's film and television lamps, the refresh rate can reach more than 20,000HZ. Yajiang's LED lamps adopt the latest PDM pulse density modulation technology to achieve frequency multiplication by subdividing PWM segments to achieve a refresh frequency greater than 10000Hz. These high-refresh frequency lamps are a very good choice for film and television shooting as well as stadium lighting.

7, lighting model improvement

We are pleasantly surprised to see that while pursuing lighting quality and technical indicators, the company has not forgotten the beauty of the appearance of the lamps. The lamps are beautifully lined and generous in appearance, making them like a look.

AUMA's RPG series of mini-lights are light-following lamps developed and manufactured using the concept of computer lights. They are compact, easy to operate, and some functions are motorized, and the color temperature is linearly adjustable. The brightness on the spot is also good. It can be said that A very lightweight and ideal mini-spotlight for use in theaters and studios.

AUMA's RPG series mini follow spot light

Alai's ARRI SkyPanel is designed with a different set of sizes to suit the different needs of different users. The S60 is medium in size and the S30 is a smaller, more portable version. Both models are available in color-adjustable color version (C) and remote fluorescent version (RP). The company also has a number of accessories for this luminaire, which is an excellent flat soft light, can also become a spotlight that can control the light zone, and can become a skylight on the stage, etc., greatly enriching the function of LED lighting. Sex.

The ETC-LED imaging light source Source 4WRDTM LED is one of the highlights of this survey. ETC imaging lamps are well known. They save the cost for the user, and the original tungsten light source imaging lamp can reproduce the brilliance. It is used for a long time and has designed a new source of Source 4WRDTM LED. This light source is almost identical in shape to the original imaging bulb, and the principle of reflection is the same. The position of the optical center (light-emitting point) is also consistent with the position of the tungsten bulb. Therefore, the original tungsten light source imaging lamp only needs to replace the new source 4WRDTM LED bulb, which will make the old imaging lamp instantly reborn and become an LED imaging lamp. Source 4WRDLED power is only 155W, which is only 27% of the traditional tungsten light source (575W). But its brightness is higher than the traditional tungsten light source (575W).

Second, intelligent effect lighting

Throughout the current stage performances and TV variety, the lighting effects are dynamic and colorful. Such eye-catching visual effects benefit from the eclectic, independent research and development and scale production of domestically produced computer lamp manufacturers based on the Pearl River Delta, enabling our performance groups and TV stations to use a large number of intelligent effect lamps with strong functions and excellent quality. Intelligent effect lighting is also the most rapid product in our industry. Every year, many new technologies, new functions and new products are on the scene. During this year's research, we have seen many gratifying changes in intelligent effect lights.

1, the lamp is waterproof

There are more and more cultural tourism and square performances nowadays, and computer lights are generally used in places where performances are performed. The performances of the Wenzhou and the squares are generally open-air, and it is inevitable that they will encounter bad weather such as rain, snow, sand and sun. Before the invention of the rainproof computer light, in the case of rain and snow, the plastic cloth was generally used as a rainproof tool, and the waterproof performance was very poor. Moreover, in the performance of rain and snow, the computer light could not be used. Later, the rain cover was invented, and the rainproof effect was not very good. Sometimes, although it rains or snows, the show has to be carried out, the lighting effect is guaranteed, and this has given birth to a new product - rain-proof computer lights. The invention of the rainproof computer light can guarantee the lighting effect of the performance all the time, which is a great progress and leap of the light.

Haoyang's G20HYBRID IP is the first IP65-class Almighty King 3-in-1 computer moving head light in GETSHOW in 2017. Its main advantages are waterproof, dustproof and anti-corrosion. It adopts IP65-class fully sealed structure to effectively prevent foreign matter such as dust, water mist and mosquitoes from entering, which can prevent the optical system from aging due to external factors, and adopts die-cast aluminum casing and cooling fan to control the working temperature of the lamp well. It slows down the aging of the lamps and the light decay of the bubbles, ensuring the service life of the lamps.

These changes can be done at the lighting console, which is very convenient. This function allows the designer to choose the appropriate power to use according to the throwing distance. If the distance is far, you can choose high power. If the distance is close, you can choose low power, which is very convenient to use.

Pearl River's variable power smart computer lights

5, the index has improved

The Pearl River's Zunergy 2000 Series PR-6000 is a computer lamp with gas discharge bulbs with a color rendering index of 96. The color discharge index of the gas discharge bubble source can reach 96, which can restore the original color of the object to be photographed well, and has the function of pattern cutting. These excellent functions are a good choice for the lighting designer to use it as a face light.

Haoyang's GL-6H and AUMA's Aress-P6 are 600W LED light source pattern cutting lamps, and the color rendering index is also very high, reaching more than 90.

6, the optical path is optimized

By optimizing the optical path optical system, the light-emitting efficiency of the three-in-one computer lamp has been greatly improved.

Haoyang's G20HYBRID IP Almighty King 3-in-1 computer moving head light uses a dual-optical optical system to instantly switch beams, patterns, and dye modes. In beam mode, the lens and other components are removed from the pattern and dyed, while the lens and other components are not used by the beam. In the pattern and dye mode, lenses and other components that are used by the beam and are not used for patterning and dyeing are removed. In this way, both the sharpness and the impact force in the beam mode can be ensured, and the high spot uniformity in the pattern mode and the dyeing mode can be achieved, and the light-emitting efficiency is higher than that of a three-in-one computer lamp of an optical system. The effect of a traditional single-function computer moving head light.

7, the heat is smart

Desheng's model MH-470/330 is equipped with an intelligent software system that adjusts the fan speed. Because this is a three-in-one computer light, there are beam mode, pattern mode and dyeing mode. The lamp temperature is different in different modes. In different modes, the fan speed is dynamically adjusted to meet the temperature regulation requirements.

8, the lights are flying

The use of wireless power allows the luminaire to remove the power cord and signal line, making it more flexible and flexible to use. This year's Spring Festival Evening appeared in the Guilin branch of the "outside flying lights" ------ Hao Yang's "outside flying lights - F0S360" system. The "Flying Sky Lights - F0S360" system consists of G20HYBRID IP computer lights, mobile power and wireless control systems. It is not only waterproof, dustproof, anti-corrosive, but also low in energy consumption. The most important thing is that it does not need to be powered by wired power supply, but it is powered by a large-capacity mobile power supply. It can directly supply 220V voltage and easily drive the whole lamp to run at full power. It can provide wireless power supply for up to 360 minutes. Where it is not easy to lay wired power, you can still design computer lights to complete the artistic creation, so that designers have more space for free imagination.

Fourth, mechanical hanging system

The mechanical suspension system is a key component in the TV studio and the stage theater lighting system. It is an important part of the new lighting system with the largest amount of engineering, the most professional, the longest service life and the highest integration requirements. Guangdong Huachen Film and Television Stage Professional Engineering Co., Ltd., Guangzhou Siquande Lighting Co., Ltd., Zhejiang Dafeng Industrial Co., Ltd., Beijing Xingguang Film and Television Equipment Technology Co., Ltd., Beijing Beite Shengdi Technology Development Co., Ltd. It is a mechanical hanging production integration company with strong overall strength, leading technology research and development, stable product performance and rich construction experience.

Compared with the terminal equipment - the variety of models, functions and styles of the lamps and lanterns, as a one-time integral mechanical hanging equipment, whether it is a key technology, main components, integration methods, the cycle of innovation is much longer. Users' acceptance of new and old hanging techniques and equipment will not be as old and new as the treatment of lamps. The “previous wave” of hanging technical equipment will not be killed on the beach by “emerging back waves”. The new technology and old products can be performed on the same stage. Although each sings each one, each plays a different show, but the turnip greens, the users have their own good, each takes what is needed. This survey also found that although the centralized control type single-point crane and rotary lifting walking sticks occupy the publicity headlines, horizontal hangers, electric vehicles, aluminum alloy slide rails, constant force booms, electric hoists, etc. Light fixtures, active in the large and small studios.

Different types of hanging equipment coexist peacefully and do not smash each other by eliminating other modes. The continuous improvement and continuous improvement of the company itself has always been the commonality of various hanging methods and positive progress of various equipment products. In this year's survey, although there is no revolutionary replacement technology and products, everyone is relishing the improvement of the performance of many hanging equipment and the improvement of details.

In the Huachen exhibition hall in Guangdong, we tested the rotating lifting boom with a large number of anti-collision sensors, and tried the lever action lever with electric rotation; experienced the improved constant-force boom with comfortable hand and accurate positioning; Self-lifting horizontal boom with continuous improvement of details. In addition, when General Manager of Brilliance Chen Peng introduced the mechanical hanging project tailored for the multi-function hall of Zhejiang Wenling TV Station, everyone noticed: when the TV program was recorded, the top decorative cover of the multi-function hall was electrically opened, professional level. The boom is exposed; when used as a conference hall, the light boom rises into the top floor, the decorative cover automatically closes, and the entire top is bright and tidy. This kind of special-purpose mechanical hanging system for conference and broadcast multi-function solves the problem of dual-function use of many venues.
