Office chandeliers are a common type of luminaire. Office chandeliers often illuminate up and down so that light that strikes the ceiling can be used as a scene backlight or as a lighting. In the prior art, an office chandelier that illuminates both downwards and upwards usually uses a side illuminating light source and a structure in which the light guide plate guides light to the upper and lower sides to achieve upper and lower light output. This kind of chandelier usually has batwing light distribution above and below. Although the upper illuminating range is large, if the lower illuminating is a large angle batwing (generally the half-light intensity angle is above 150°), many light energy is not concentrated in effective illumination. In the area, light energy utilization is low and glare is high.
