Common LED beam lights use dedicated concentrating cups, and LED illuminators are used in fully transparent concentrating cups. However, the LED tube and the concentrating cup are combined into one module, and the luminous flux is not satisfactory. In this case, the solution is to combine the same modules once again to make it a planar LED array. A light of more than one hundred watts of LED luminaires is announced, suitable for the brightness of several hundred watts of tungsten incandescent lamps. After a lot of LED lighting, the glare that meets the needs of the stage has been able to satisfy the needs of the stage and the energy-saving effect.
Recalling the color light used in stage lighting, it is a method of adding colorful color filter paper or other color filters in front of white-emitting lamps. The drawback is that many undesired shades of light are blocked, and the emitted shades are appropriately weakened. Due to the characteristics of the human eye, the red and blue-violet colors on both ends of the visible spectrum are exceptionally insensitive, and many people's sensitive light is blocked. The luminaire's luminous power is even lower. For example, in order to avoid high-temperature fading of the color filter, the color filter transmits a large amount of infrared components in the spectrum, and the blue color filter transmits a short-wavelength blue light together with some long-wavelength red light. Therefore, the blue light obtained by adding the blue color filter before the incandescent lamp is not weakened by the brightness, the color is not pure, and the actual effect is not satisfactory.
When the incandescent lamp is installed with a blue color filter in front of the lamp to obtain blue light, when the LED requires a certain color light, only the spectrum that is not required is announced, and the color spectrum of the desired spectrum is declared. Since the blue brightness of the LED lamp is suitable for the brightness of the incandescent lamp with a power of more than ten times plus the blue color paper. Therefore, the color light of the LED lamp is too pure and bright in practical use, in order to reduce the saturation of the color light, and even some white LED light beads to generate a rich color light.
The luminous power of LEDs is higher than that of incandescent lamps. The luminous efficacy of lamps is also higher than that of ordinary incandescent lamps. The power of color light is much higher. Therefore, light planners have found that LED lamps are used for the colorful colors required for stage performances. Light, more can fully promote the benefits of LED.
Since the continuous presentation of blue, white and high-brightness LEDs in the last century, the luminous power has been continuously improved, and the advantages of tens of thousands of hours of life, switching speed, dimming, bright colors, energy saving and environmental protection have begun to attract the attention of the industry. However, although LED stage lamps have shown significant advantages in the internship, they have not been widely used in stage performances. The elements come from many aspects, including: high quotation, single type, and poor quality.
Even so, with the continued development of the profession, the leaps of skills are broken, the use of the promotion, the LED light efficiency is also constantly improving, and the quotation continues to fall. The presentation of the new combined die also increases the power of individual LED tubes (modules). After continuous efforts by the industry, the breaking of new optical planning, the development of new lights, and the single commodity situation are expected to be further changed. The improvement of the control software also makes the LED stage lighting more convenient. These gradual changes have shown that the LED lighting is widely used in the stage.
