According to the relevant practitioners introduced, LED lighting performance in terms of color better than conventional light sources. Currently, LED lighting applications at the stage, and more will adopt respectively red, tricolor LED tube combination of green and blue light use, are mixed to form white light illumination mode. Take LED lamps compared with incandescent lamps, the luminous efficiency of LED tube is more than twice higher than incandescent bulbs, light-emitting diodes using its small size and low temperature characteristics, using a more efficient optical design, the use of light flux rate higher than incandescent lamps stage several times. Even the same luminous flux, than incandescent lamps LED lamp power several times. Therefore, lower power LED lamps can achieve the requirements of the stage light intensity required.
LED interior optical design is called first design, concentrating cup designed for the second design, concentrating cup for the third module combination design - It has been so evaluated. Currently more common LED beam lights are dedicated condenser cup, LED light-emitting diodes mounted in a fully transparent condenser cup. However, the combination of the LED and condenser cup into a module, the luminous flux is not enough, in this case, the solution can be identical to a combination of modules again make this LED array plane. One hundred watt light LED lamps emit equivalent brightness of a few hundred watts of tungsten incandescent lamps. So through a large number of LED light, the light that meets the needs stage, the stage has been able to meet the needs of the application and compliance with energy efficiency.
With the incandescent lamp in front of the installation by the blue color filter to obtain a blue light is not the same method, when the LED requires a shade, only reduce unwanted spectral issued, and the desired spectrum of colored light can be emitted. Because the blue LED light brightness equivalent to ten times the brightness of a power greater than incandescent lamps plus blue color of the paper. Therefore, LED lamp shade in actual use seems too pure bright light, in order to reduce the saturation of shade, and even some plus glowing LED lamp beads, to produce elegant shade.
Since the last century, blue, white and high-brightness LED start to appear, the luminous efficiency continues to improve, tens of thousands of hours life, fast switching, dimming convenience, bright shade, energy saving and environmental protection, etc. began to insiders attention. However, LED stage lighting, although in practice, showing a clear advantage, but has not been popular in the stage show, from a wide range of factors, including: high price of a single species, the quality varies, and so on.
Even so, with the continued development of the industry, leap technology breakthroughs, and vigorously promote the use of, LED light efficiency is improving, prices continue to decline. The new modular die appearance, but also to the power of a single LED tube continues to increase. Through continuous research and development efforts with the industry, breaking new optical design, the new lamp species development, product single situation is also expected to further reverse. Improved control software, but also makes use of more convenient LED stage lighting. These gradual changes are reflected in the prospects of LED lighting applications in the broad arena.
