摘要： An improved light assembly includes aligned directional light sources mounted one behind another. A distal one of the light sources occludes light emitted from a proximal one of the light sources. A reflector is interposed between the light sources, with a convex surface facing the proximal one of the light sources. Thus, the light assembly projects a light field extending at least through an 180° hemisphere, and up to about 270° backwards from the forward orientation of the light field, well-illuminating lateral approaches to the assembly.

摘要： A lamp body includes a light source, a light guide body configured to cause light from the light source to be guided and cause the light to be emitted from a light emitting surface, a reflector configured to cause the light, which has exited from a light guide exit surface of the light guide body, to be reflected toward a side of the light emitting surface; and a half mirror disposed to face the reflector and having a reflection area where the light reflected by the reflector is reflected toward a side of the reflector and a transmission area where the reflected light is transmitted. In the light guide body, a first light guide lens causes the light to be guided in a first direction and a second light guide lens has the light guide exit surface from which the light exits in a second direction intersecting the first direction.
