发明名称 Lighting device
摘要 A lighting device, for illuminating display designed parts on a display plate arranged parts at-least-partially around a center axis, includes a light source for emitting light and arranged at a rear side of the display plate, and a light guide body having at least one light guide portion including an inner portion and an outer portion. The inner portion has a rear side surface for receiving the light from the light source and a front side surface with a curvature for reflecting the light to change a forward-backward direction of the flight inputted from the light source toward an outwardly radial direction to guide the light so that the light can travel in the outer portion in approximately radial directions centered on the center axis and be suppressed from diffusion from a central line passing through though the center axis and the light source.
