Choose light, reasonable facade lighting method, manipulation of the lighting area, lower power consumption. Handle the intensity of illumination, light color and color rendering, stereo feeling, texture, flash, glare constraints, the indicators such as. Attaches great importance to the spatial resolution, eliminate unnecessary shadow, manipulation of the sunlight and ultraviolet (uv) radiation on people and objects. To the brightness of the invention is suitable for spreading and illuminance level, constraint glare, cut fidgety. Should be the effective use of natural light, outdoor light, the requirements of the light pole lift the top of the light, with lightning rod, cover, and 60 degrees spread pulleys and 120 degree of spread of hook system. Cover to avoid the rain into the light pole, avoid lifting pulley parts corroded by rain. Light, pulley block is used to avoid the wire rope, cable groove winding. Hook system design is very reasonable, when the light falls to lifting operation system make the hook turn actively, to ensure that wire rope in the lifting action end secure after unloading, prolong the service life of wire rope.
