LED stage lighting lamps, stage lighting as a kind of artistic lighting, the brightness, light effect, color temperature, color rendering, dimming, light controllability and flash characteristics of the light source must meet certain requirements. Traditional stage lighting mainly uses halogen tungsten lamps, xenon lamps and so on. Take the halogen tungsten lamp as an example In-line LED Lights. Its characteristic as a stage lighting source lies in the spectral continuity of the thermal radiation source, with a color rendering index ranging from 95 to 100, which is close to an ideal light source. When the color temperature or light color conversion is required, a filter is required in front of the light source. The filter has the characteristic of selective absorption of light, and a new light color can be obtained by configuring filters of different chromaticity. Although tungsten halogen lamps can achieve satisfactory color rendering and meet the color requirements of artistic creation, its shortcomings are also obvious In-Line Led Lantern. In the light-emitting process of the halogen tungsten lamp, the luminous efficiency is low, and most of the electric energy will be lost in the form of heat radiation, which will cause the temperature of the lamp body to rise significantly, and there are hidden safety hazards in the application process. At present, domestic and foreign lighting manufacturers directly use white LED Light sources for stage lighting. The internationally accepted white light LED is the luminescence mode of blue excited phosphors, and its color rendering, spectrum and visual effects are the same as the light color indicators of tungsten halogen lamps. There are obvious differences In-line Lamp Beads. Although the general color rendering index of some LED stage spotlights can be as high as 90 or more, due to the high blue light component and low red color in the spectrum, it is obvious that the color reproduction, light color effect, artistic expression and other aspects are not available during use In Line LED. Meet the requirements of stage lighting personnel, which is also a serious shortcoming in the basic lighting of LED stage lamps recognized in the performing arts industry.
