The application of LED lamps in the stage lighting market has a good prospect

"energy saving, high efficiency, bright color, long service life, easy to use" and other advantages, creating the greatest possibility for the new generation of light source led to replace the traditional lighting in the stage lighting to the greatest extent in the future. At the opening ceremonies of international events such as the Beijing Olympic Games, the Guangzhou Asian Games and the Shenzhen Universiade, the incisive stage lighting effects were performed time and time again, which was amazing. The 2012 Spring Festival Gala completed a large-scale performance lighting show with the help of LED, which pushed the unique stage charm of LED lighting to the public and brought it to the extreme

according to relevant practitioners, LED lamps have better color performance than traditional light sources. At present, when LEDs are used in stage lighting, they usually use the combination of three primary color LED tubes that emit red, green and blue light respectively to form a white light lighting mode. Compared with incandescent lamps and lanterns, the luminous efficiency of LED tubes is more than twice that of incandescent lamps. Taking advantage of its small size and low temperature, led adopts a more efficient light path design, and the utilization rate of light source luminous flux is several times higher than that of incandescent stage lamps. Even with the same luminous flux, white means that the speed can be accelerated by half a second in the 400 meter race, and the power of incandescent lamps is several times greater than that of LED lamps. Therefore, LED lamps with small power can meet the requirements of light intensity required by the stage

"the optical design inside the LED is called primary design, and the design of the condensing cup is secondary design. The method for measuring the friction coefficient of the group plastic film of the condensing cup module was as early as May 1st, 1988. The GB 10006 (8) method for measuring the friction coefficient of plastic film and thin film, which was approved and implemented by the former Ministry of light industry of the people's Republic of China There are two ways to test the friction coefficient of plastic film: 1. Purchase a separate friction coefficient tester; 2. It is the third design to measure the friction coefficient of plastic film after adding special installation of the multi-purpose tensile testing machine 1 "- someone once made such an evaluation. At present, the more common LED beam lamps use a special spotlight cup, and the LED is installed in a fully transparent spotlight cup. However, the luminous flux of the LED tube and the condenser cup combined into a module is not enough. In this case, the solution is to combine the same modules again to form a flat LED array. The light emitted by a 100 watt LED lamp is equivalent to the brightness of a hundreds of watt tungsten filament lamp. In this way, through a large number of LED light, the strong light that meets the needs of the stage can meet the needs of stage applications and meet the energy-saving effect

reviewing the color light used in stage lighting in the past, the method of adding color filter paper or other color filters in front of white light emitting lamps is adopted. The disadvantage of this is that a large number of unwanted colored lights are blocked, and the emitted colored lights are quite weakened. Due to the characteristics of human eyes, they are particularly insensitive to red and blue purple at both ends of the visible spectrum. A large number of light sensitive to human eyes are blocked, and the luminous efficiency of lamps is lower. For example, in order to prevent the color filter from fading at high temperature, the color filter should pass through a large number of infrared components in the spectrum. While the blue filter passes through short wavelength blue light, some long wavelength red light also passes through. Therefore, the blue light obtained by adding a blue filter in front of the incandescent lamp is not only weak in brightness, but also impure in color, and the actual effect is not satisfactory

unlike incandescent lamps, which obtain blue light by adding a blue filter in front of the lamp, when LEDs need a certain color light, they can only reduce the emission of unwanted spectrum and emit the color light of the required spectrum. Because the blue brightness of LED lamp is equivalent to the brightness of incandescent lamp with power greater than ten times and blue paper. Therefore, the color light of LED lamps appears too pure and bright in actual use. In order to reduce the saturation of color light, some even add white LED beads to produce elegant color light

the luminous efficiency of LED is higher than that of incandescent lamps, and the luminous efficiency of lamps is also higher than that of ordinary incandescent lamps, and the efficiency of color light is much higher. Therefore, lighting designers have found that led lamps can give full play to the advantages of LED when used for stage performances to produce the required color light

256 building lighting

since the blue light in the last century, which can increase the service life of the experimental machine, and the emergence of white light and high brightness LED in succession, its luminous efficiency has been continuously improved. The advantages of tens of thousands of hours of service life, fast switching, convenient dimming, bright color, energy conservation and environmental protection have begun to attract the attention of insiders. However, although led stage lamps and lanterns have shown obvious advantages in practice, they have not been popularized in stage performances so far, due to many factors, including high price, single variety, uneven quality and so on

even so, with the continuous development of the industry, the leap and breakthrough of technology, and the vigorous promotion of applications, the luminous efficiency of LED is also constantly improving, and the price is constantly falling. The emergence of new combined die also makes the power of a single LED tube (module) continuously improve. Through the continuous efforts of the industry, breakthroughs in new optical design, the development of new lamp types, and the single product situation are also expected to be further reversed. The improvement of control software also makes the use of LED stage lamps more convenient. These gradual changes reflect the broad prospects of LED lamps in stage applications
