Residential Led street lamp

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) advantage of the characteristics of its small size, low temperature, using more efficient light path design, the utilization rate of luminous flux is several times higher than incandescent bulbs. Under the same luminous flux, incandescent light emitting diode lamp is the power of a few times. Stage, therefore, the light intensity can be achieved by low power led lamp to meet. Compared with the traditional light source, led lamps and lanterns has better color performance. At present, the light-emitting diodes (leds) used in stage lighting, usually will be red, green, and blue light trichromatic leds tubes into white light lighting model. In the past, use the color of light in the stage lighting are by adding the color filter in front of a white light the lamp shade or other color filters. It has the following disadvantages: a lot of don't need the color of light is blocked, the launch of the color and light is rather weak; In addition, due to the nature of the human eye, the light of red, violet, particularly at the ends of the visible spectrum is not sensitive to block a large amount of sensitivity to the human eye light, make the lamp luminous efficiency is low. For example, in order to prevent color fade at high temperatures, color filter must be a lot of the infrared transmission spectra of the ingredients. When the blue filter blue color transmission short wavelengths, some long long 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, and the 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 diode need specific colors of light, only reduce unnecessary emission spectrum, and the launch the colors of the spectrum. Because a blue light emitting diode lamp brightness is equivalent to an incandescent lamp brightness, its power is greater than a light emitting diode lamp with ten times as large as the brightness of the blue paper. Therefore, in actual use, the color of the light emitting diode lamp light is too pure, so bright, so 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. Light emitting diode lamp [ 。 jschindo。 com] Luminous efficiency than incandescent lamp, the luminous efficiency is higher than ordinary incandescent lamp. Color of light efficiency is much higher. Lighting design, therefore, researchers found that, in the stage performance when using leds light to produce the required color light, can give full play to the advantages of light-emitting diodes (leds). Blue light, white light since the last century and the advent of high brightness leds, they constantly improve the luminous efficiency. Tens of thousands of hours of service life, convenient quick switch, dimmer, bright colored lights, and the advantages of energy conservation and environmental protection has already started 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, has not been promoted in the stage performance.
