Summary is to review and analyze a certain period, a certain project or a certain work afterwards, so as to draw regular conclusions, which can help us sum up our previous ideas and carry forward our achievements, so we should make a good summary and write a good summary. So do you really know how to write a summary? The following is a summary of my carefully arranged lighting work. Welcome to share.
Summary of lighting work 1 This is a bright pearl with passionate melody and graceful movements.
Here is the performing arts hall, which carries the mission of national cultural rejuvenation and brings together the collision of world art exchanges. The crystal-clear oval shell shines brightly under the sunlight, and is decorated with extremely clear lake water, just like a bright pearl on the water, "the theater in the city, the city in the theater", which is one of the most representative modern buildings in Beijing-the National Grand Theatre. The National Grand Theatre is a combination of tradition and modernity, romance and reality, with novel and avant-garde modeling and unique conception. I heard the name of the National Grand Theatre a long time ago. When I first saw its pictures on the Internet, I was attracted by its unique shape. Now I can finally experience this great architectural work myself. On the morning of September 13, 20xx, we went to the National Centre for the Performing Arts as an intern under the guidance of our teacher. During the whole internship, through the teacher's careful explanation and the visit to the Grand Theatre, I got a deeper understanding of the National Grand Theatre and benefited a lot.
Overall perception
This is the view from the left side of the entrance to the National Grand Theatre. The National Grand Theatre is a unique shell shape, creating the best of three worlds, two of which are the largest domes in the world in appearance. The steel structure of the whole shell weighs 6475 tons, and the long axis span from east to west is 2 12.2.
Rice is the largest dome in the world at present; It is the deepest underground building in the world.
The deepest point is -32.5 meters, which is equivalent to digging 10 layer underground. The National Grand Theatre is 46.68 meters high, slightly lower than the Great Hall of the People, with a total length of more than 600 meters. Surrounded by an artificial lake with an area of 35,500 square meters. There is an artificial lake around the shell, and the color of the lake is rippling. The lake is like a crystal-clear mirror. The waves and reflections complement each other, and * * * holds up this huge and crystal-clear building. In fact, this lake originated from a big pit on the land before. An office building was originally planned to be built on this land, but the project was cancelled, leaving a dug pit. According to the current situation, designer Andrew designed this place into a big water surface. From a distance, the whole building is in close contact with the lake. As a matter of fact, when we walked into the building, there was no lake outside eureka tower 1 Mido, and the lake was actually separate from the building. The whole shell style is simple and atmospheric, just like a crystal clear water pearl. The surface of the shell consists of more than 20,000 titanium plates and 1200 ultra-white transparent glass. The ingenious combination of the two materials creates a visual effect that the stage curtain is slowly opened. Whenever night falls, you can see the magnificent opera house through the gradually opened curtain. The scattered "mushroom lights" on the shell echo the distant night sky like misty stars, which makes the Grand Theatre full of subtle and unique charm and beauty.
Internal view victory
We entered the Grand Theatre from the north entrance next to Chang 'an Avenue, passing through the North Underwater Corridor → Olive Hall → Public Hall → Three theaters in turn. Through this tour, I feel that the National Grand Theatre is far from an unusual performance center, but a city permeated with science and technology and art. ...
Entering from the north entrance of the Grand Theatre, the first thing you pass is an 80-meter underwater corridor. The top of the corridor is all used.
Glass ceiling, during the day, the lake above is sparkling, layers of ripples can be projected on the floor and walls, and at the same time, they complement each other with the dense bubble-like decoration on the wall, so that people in it seem to have entered a "future water world" that is also true and illusory; At night, in two rows of finely carved glass.
Under the guidance of the lamppost, the audience gradually moved away from the noise at the entrance. A good play is about to begin behind the mysterious golden and bronze door ahead, and a romantic and pleasant journey is about to set sail. There are art exhibition halls on the east and west sides of the North Underwater Corridor, and various art exhibitions are held all the year round.
Through the underwater corridor, you walk into the olive hall. Olive hall because of its
Space is shaped like an olive, hence its name. The two gates are dignified and elegant, with 180 oval protrusions on them, which are not only the deformation and evolution of the ancient doornail in China, but also the overlooking effect of the small theater, realizing the ingenious grafting and perfect integration of China elements and modern design. At the same time, this * * * 360 small ellipse symbolizes that the National Grand Theatre has performances every day for 365 days a year, and it never stops.
Walking out of the Olive Hall and through the public space, we entered the Opera House, the core part of the National Center for the Performing Arts. As soon as I entered the opera house, it gave me a radiant feeling. The whole opera house is dominated by dazzling gold because it is red.
Color, coupled with gorgeous lighting, the entire opera house is brilliant and gorgeous. In detail, there are two air conditioning outlets under each seat to adjust the temperature. The ballet table is made of Oregon wood, and the three-layer structure is used to increase flexibility and protect the ballet dancer's toes. In the Opera House, I mainly observe its walls. The metal mesh wall in the opera house is its greatest attraction. An arc-shaped metal mesh is installed on the wall, and sound can pass through the metal mesh, and the wall behind the metal mesh is multilateral.
In this way, the visual arc and polygonal auditory space are achieved, the perfect combination of architectural acoustics and theater aesthetics is realized, and the reverberation time reaches 1.6 seconds. Even without a microphone, the sound on the stage can be heard by audiences in all corners of the stage. The back wall of the auditorium is the main source of echo, and sufficient broadband sound absorption materials are made on the back wall. In order to coordinate the specific structure with the decoration style of the audience hall, the purple silk cloth is followed by glass silk cotton sound-absorbing material. This shows how much effort the designer has spent on the detailed design.
Out of the opera house, we came to the concert hall. My first feeling when I entered the concert hall was solemnity. Compared with the Opera House, it is more artistic. Being in it, I seem to feel the solemn atmosphere of the ongoing music performance. The concert hall is dominated by white, which is solemn, quiet, fresh and elegant. The opera house has two biggest attractions. The first is the ceiling. The ceiling of the concert hall is like an irregular white relief, like
The undulating sand dunes, like beaches washed by waves, have a very beautiful appearance. At the same time, this design is conducive to the spread of sound. In order to achieve the perfect sound effect, a centralized soundproof board made of fiberglass concrete by Tsinghua University students was hung under the ceiling to scatter sound in all directions. This design makes the concert hall achieve the perfect combination of architecture and acoustics. Another attraction is that there is the largest organ in the world in the concert hall, which is the treasure of the town hall. It is said that the cost has reached 30 million, what a huge figure! It is said that only one person in China can play this organ at present.
As the theater was closed that day, we went out of the concert hall to visit the public hall of the Grand Theatre. The public hall has the most scenic spots, and the first thing that impressed me most is the mahogany dome. The dome is made of rare Brazilian mahogany and divided into several areas by metal strips. Each piece of mahogany has different shades of color, and the collage trend in each area is different, full of changes and levels. Looking around, the sky seems to have drawn a rhythmic arc. The whole dome is full of agility and jumping spirit, as if entering the music world inside the instrument. The bright crimson tone coincides with the traditional aesthetic taste of China. Brazilian mahogany used to decorate the dome is also extremely expensive. It is said that each piece costs thousands, and it costs tens of millions to decorate the whole dome. second
The attraction is the huge glass curtain wall. Due to the shape of the Grand Theatre, each piece of glass that constitutes the glass curtain wall has a different shape, and it must be cut extremely accurately to be perfectly assembled. The glass curtain creates a scene where the curtain slowly opens on the stage. Strolling in the Grand Theatre, you can see the prosperity of Chang 'an Avenue through the glass curtain. For pedestrians outside the theater, they can also see through it.
Summary of lighting work 2. Preparation before performance
(1) unpacking inspection of equipment: before the performance every day, go to DJ station to check whether the unpacked equipment is normal; During the equipment startup process, check whether the peripheral equipment and power amplifier are turned on normally (the equipment startup process is peripheral first and then power amplifier); After all the equipment is turned on, whether the use of various equipment works normally; Then go to the DJ station to listen to the audio and see if the audio output of the computer and MD is normal. Check whether the frequency bands of microphone and receiver are the same!
(2) Review of program list: check and sort out the program list handed in by the actors before the opening every day, check whether there is any repetition in each accompaniment, check whether there is any time delay in the beginning of each accompaniment, and make records in advance. (The above three points must be done every day to ensure the smooth performance. If there is a new actor, communicate with him in time some matters needing attention in the sound field of our factory, such as the location of monitoring. , and don't shout wheat. At the same time, inform the arrival of new actors in each position in time and make preparations for cash withdrawal.
Second, the performance at work
(1) Vocal proportion of accompaniment: During normal performance, the ratio of accompaniment to vocality is 60% and that of accompaniment is 40%, which highlights vocality.
(2) On-site debugging of accompaniment, voice and reverberation: Accompaniment sometimes leads to poor sound quality after revision, so Demon conducts on-site debugging to attenuate and enhance the treble, alto and bass of accompaniment, so as to achieve the effect of bringing out the best in each other; Voice, each actor's voice line is different, sometimes it explodes, sometimes the voice is not penetrating, and it needs on-site debugging (now only dare to move the high notes of the microphone channel); Echo, because each type of accompaniment is different, so the original song and rock music must be matched according to the type of accompaniment and human voice. There are many kinds of original music. For example, songs such as "Prairie" must be echoed loudly, reflecting the vast sense of grassland. Rock music is different, just moderate, but not too big)
(3) Check the equipment during the performance: sometimes the sound pressure is too high during the performance, which causes the power amplifier to flash yellow and destroy the sound, so it should be controlled according to the proportion of the actor's voice and accompaniment, and form the habit of checking the surrounding equipment at any time; Recently, two new microphones were installed. The use of microphone is not stable, and frequency and power failure frequently occur. Reinstall the battery after troubleshooting the power supply. The remedy for the off-frequency phenomenon is to reduce the sound pressure of the microphone and communicate with the actors without shouting.
(4) Howling phenomenon: Sometimes in the process of performance, there will be howling phenomenon. When this phenomenon occurs again, first press down the sound pressure, then find out the reason for the excessive accompaniment, sound or echo, and adjust it in time.
(5) The concept of scene: As a sound engineer, the scene is the most important, and the titles of various programs should be coordinated and skillful. On the other hand, we should interact with actors, be flexible, cooperate with each actor to create the highest atmosphere, and cooperate with VJ division and lighting division. The start, end or connection of each program and each accompaniment should be notified in time and coordinated.
Second, other aspects.
1, familiar with the speed and color of each material. Basic understanding of the structure of flashing lights, independent maintenance of small problems (such as equipment sequence, replacement), learning to debug the address code of flashing lights. Basic understanding of the structure and connection of LED screen. The independent transmission card is connected to the first screen through a flat cable. The connection of each screen is connected to each screen by signal cable in turn, and each screen has an independent power cable.
2. Be familiar with the types of accompaniment, adagio and original sound. Slow-motion accompaniment is familiar with the rhythm, speed, empty beat, intermission and climax of accompaniment, and gives appropriate materials according to these. The original lyric music is divided into warm tones and cold tones, and appropriate materials are given according to the rhythm, speed, empty beat, intermission and climax of accompaniment. Pay attention to the lighting when feeding, whether the feeding is eaten up and whether it is matched. Material and lighting match. Maintenance and awareness of equipment
3, the basic understanding of the sound structure, the sound is broken, when maintenance, open the back cover and take out the motherboard (frequency divider), use a multimeter to measure whether all parts of the motherboard are connected, and use 10 battery to play the sound unit. If there is no damage, each unit will ring.
4. The running line must be horizontal and vertical, and recorded at the starting point and end point of the running line. The signal line and the power line are the same, and the lines should be connected in parallel. All line connectors must be welded with electric soldering iron. At the same time, I learned a lot about the line in the process of doing the project.
5. Basic understanding of Yamaha MG 166cx mixer, basic understanding of the functions and usage of each key in each channel. There are still some details to be studied. The ratio of power amplifier to speaker is 0.5 times of 65438+ audio, and the audio output control switch of power amplifier should be turned to the maximum to avoid the overload of power amplifier caused by a small horse-drawn cart.
6. Learned the binary LED lamp address code algorithm.
7. Know how to adjust the frequency band and sensitivity of microphone and receiver.
Summary of Lighting Work 3 With the rapid development of social science and technology, rapid economic growth and the reform of industrial structure, the lighting industry has developed rapidly in recent years, and the upgrading of lighting technology has reached an unprecedented speed. Therefore, we organized a one-day tour of xx TV station, and got a deep understanding of the role and present situation of lighting, which laid a good foundation for entering social work in the future.
First of all, the person in charge of TV lighting introduced the current situation of TV lighting layout and demonstrated it for us. Then we communicated with it and asked about the lighting method, experience and how to deal with problems. Understand the current lighting, lighting industry prospects and talent needs. The requirements, basic literacy and technical requirements of lighting personnel are studied. After that, we visited the console under the leadership of other personnel and got a brief understanding of the responsibilities of each station.
In the communication with lighting people, their ideas are mostly unified, that is, to do lighting for several years, accumulate experience, learn more about the basic operation of lighting control, fully adapt to, be familiar with and use the environment, and lay a good foundation for future promotion.
Then, pointing to the three main lights overhead, he told us that this is a spotlight of about 3000. Spotlight used on the stage refers to the use of a plano-convex condenser in front of the lamp. This kind of lamp can adjust the spot size, and the emitted music beam is relatively concentrated, with less diffuse light beside it. The power varies from 0.5W to 5KW, and the focal length is divided into long, medium and short according to the shooting distance. Then in the audience, they mainly use led dyeing lights, which can provide RGB color mixing and comprehensive color mixing effects. Pure and rich in color, it is widely used for color development in large variety shows and entertainment places. The shell is made of die-cast aluminum and aluminum alloy, and the waterproof grade can reach IP55/65. In addition, the lamps and lanterns adopt advanced appearance design, which is unique, firm and compact, and has the characteristics of simple operation, safety and reliability. Small light attenuation is also a major feature, and independent control system is convenient for independent debugging of lamps and brightness programs.
In addition, pattern lights are also used to illuminate characters with point light sources. People's backlight, as well as computer shaking lights, are also widely used here. Shaking head lights are generally used on the stage, and professional shaking head computer lights are high-tech products integrating electronics, machinery and optics. Qualified professional computer shaking head lamp must be stable and reliable, with excellent light efficiency, accurate positioning and good heat dissipation, and the lamp body and material structure meet the requirements of ergonomics.
In fact, these lights can be used as computer lights, including, in the early days, the lighting of dance halls was very simple, including spotlights, downlights, rain lights and some heavy mechanical lights. With the development of electronic technology, simple sound-controlled mechanical lights have appeared, which can reflect patterns, change colors and change projection angles. But these lights are acting alone, and it is impossible to be uniform and in step. In 1980s, a new type of lamp, named computer lamp, appeared, which combined lighting technology with computer technology. Several, dozens or even hundreds of computer lights can change patterns and colors together according to the lighting design requirements, and the speed can be fast or slow, and the scene is magnificent and breathtaking. The appearance of computer lights is a leap in the development history of stage, film and television and entertainment lighting, and it also gives people a new understanding of lighting technology.
Through this visit, I learned that colorful and unpredictable lighting effects are people's first impressions of lighting. These effects come from various professional lamps. This is what people call professional lighting.
