<br> <br> At the beginning of the century, traditional opera stage, can only rely on gas light or ordinary lights for lighting, lighting few changes, the contents of the drama and character portrayal of depends mainly on inside the actors sing, .recite, to the accompaniment of music, playing and to reflect that this is of course the Chinese Opera's traditional aesthetics, but also demonstrates the application of that technology. But since the middle of the 20th century, science and technology development has been the stage lights .gradually become an art, contemporary stage lighting colors, strong or weak, the actual changes have been made with the music, stage art and artists performing together, become depiction hero inside important means to write, you can write, but charming, d'un .by colorful light, light wall, the light curtain, in part or in whole, static or dynamic change the stage becomes spectacular, effectively activates the entire stage space, was described as light to create the fourth dimension of the stage. Modern stage lighting art .has been the world as a way to energy conversion as silent perceptual's artistic language, used to express an idea, a feeling and a moral, and even called the "soul" of the stage. <br> Color is an important stage lighting in the .amount of ingredients, it changes has a direct impact on art, even if it is the traditional theatre and drama, now is growing without color changes, large dance performance in addition to intelligent lights and color changing lights outside, the rest of the stage lighting .has almost with a color change. Therefore, in the contemporary performing arts performances, digital color transfer has become extremely important in the lighting equipment, change the color quality is good or bad are also directly related to the show's success. <br> The color .change in the production history of the 20 years anniversary, has been relying on the positioning of the simulated bridge balance change color picker to full digital control change color picker, and have adopted a communication signal, the DMX512 change color picker control basic be unified. .Now, with the bulk change color picker console computer, through the amplifier or allocator can control thousands of color change, meet a variety of artistic performances and in all kinds of occasions. Such as night Sun company produced 11 color digital change color picker technology leader ., a positioning system dynamic optical high accuracy encoder position is very accurate, regardless of performance parameters, or the appearance of the process is very good. <br> In recent years, changing the color of the manufacturing standards and reliability of raising product series also .gradually improve, but due to the lack of industry guidance, many manufacturers provide the user with instructions in the specification to describe functionality, but lack some of the key technical data and specifications, and its technical terminology, the main technical indicators and measurement methods are .not uniform, with the result that the manufacturers of quality there is a larger difference. Our digital color changing capabilities for scientific analysis, presented important technical parameter under the same conditions tested. According to the color changing actual usage to ensure safe and reliable as the .main specifications: <br> 1 appearance and technology: <br> The appearance of the product and the process is the guarantee of product quality in important indicators to detect content including: structure and clear, smooth surface decoration or coating, solid and reliable; .the text symbol identifies clear, consistent with the relevant standards; surface without scratches, hanging stream; internal wiring technology and component installation requires clean, secure, reliable, good ventilation and thermal performance; various operations switch flexible and reliable. <br> Test method .: test and Visual. <br> 2. Security: <br> Insulation performance and adaptation to the voltage should be consistent with the national e-performance technical requirements; amplifier using power categories to match; the color change is fixed in the light of .the Board and the safety chain. <br> Test method: test using high voltage or high voltage shake table test and Visual. <br> 3. main technical indicators and measurement methods: <br> (1) the most quick change color: .<br> Back to light the average color of the fastest changing color is the color will be changed from one end of the artist's first color conversion to the last color of total time and total heat exchanger chromatic number ratio and the adjacent monochrome conversion time of .verification. Using digital stopwatch three times the average after the test. <br> (2) change color accuracy: <br> To visually and measuring, in arbitrary color operation mode, check the accuracy of the color change and repeat positioning accuracy of color .change (≤ 3mm) and check for overshoot, the test three times. <br> (3) change color of synchronization performance: <br> With 6 sets the color changing color change at the same time, use Visual mode to check each color .change color of synchronization, the test three times. <br> (4) tensile force: <br> Rally of dollars by tapes will stuck and colour on paper (from the first one started), start swapping color picker, the question to read .the rally after balance and stability. 6 changing color picker pull for average. <br> (5) noise: <br> Use the sound level meter, A weight, distance 6 change color picker centerline a metres respectively in static and continuous change colors .for testing. <br> <br> <br> <br>.
