LED street light compared with incandescent lamps and lanterns of lamps and lanterns, LED tube, more than twice that of incandescent lamp, luminous efficiency light-emitting diodes (leds) advantage of the characteristics of its small size and low temperature, the more efficient light path design, the lamp flux utilization stage than incandescent lamp
compared with incandescent lamp, incandescent light bulbs, LED street lamp luminous efficiency is more than twice. Light-emitting diodes (leds) because of small volume, low temperature, the more effective optical path design, the utilization rate of light flux is several times higher than incandescent bulbs. Even if the same luminous flux, the power of incandescent lamp is led lamp several times. Therefore, smaller power leds lamps and lanterns can satisfy the requirement of the stage needed to light intensity. LED lights on the colour performance is superior to the traditional light source. At present, when the leds used in stage lighting, tricolor led tube with red, green and blue combination to form white light. In the past, stage lighting using color lamp is in front of a white light the lamp add color filter paper or other methods of color filter. The disadvantage is that a large number of unwanted color light is blocked, and emit colored light is reduced. Due to the nature of the human eye, to red, violet, particularly at the ends of the visible spectrum is not sensitive to the human eye is the large amount of sensitive light is blocked, causes the lamp luminous efficiency is low. For example, in order to prevent color fade at high temperatures, color filter should be a large number of infrared transmission spectra of the ingredients. When the blue color filter transmission wavelength blue light, it also some long wavelength red light transmission. Therefore, by adding the blue color filter in front of the incandescent light bulb for blu-ray brightness is weak, not only and the color is not pure, actual effect is not satisfactory. Unlike incandescent lamp, incandescent lamp through the in front of the light blue color filter installation to get blue, when the light-emitting diodes (leds) need a certain color of light, it is only to reduce unnecessary spectrum emission, and the launch the color of the light spectrum. Because leds light blue light luminance equal to ten times the power of the brightness of the incandescent lamp and blue paper. Therefore, in actual use, the color of the light emitting diode lamp light is too pure and bright. In order to reduce the color saturation of light, some people even add beads emit white light light-emitting diode, to produce elegant color light. 。 jschindo。 Com led street lamp, luminous efficiency is higher than incandescent lamps and lanterns, luminous efficiency is higher than the ordinary incandescent color of light is more efficient. Lighting designers found in stage performance, therefore, the use of light emitting diode lamp can give full play to the advantages of light-emitting diodes (leds), to produce the required color lights. Blue light, white light, since the last century and the advent of high brightness leds, its luminous efficiency enhances unceasingly, the life of tens of thousands of hours, fast switching speed, easy to move light, color bright, the advantages of energy conservation and environmental protection began to cause the attention of the industry. However, despite the LED stage light shows obvious advantage in practice, but because the price is high, the varieties of a single, quality and other factors, yet it is not promoted in the stage performance.
