Abstract
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.
Claims19
An apparatus for emitting light, comprising:
- at least two aligned directional light sources mounted one behind another and enclosed by an outer light-transmissive cover, wherein a distal one of the light sources occludes light emitted from a proximal one of the light sources;
- and
- a reflector interposed between the light sources and supported inside the outer light-transmissive cover by an inner light-transmissive collar that encloses the proximal one of the light sources and the reflector, wherein the reflector has a convex surface facing the proximal one of the light sources configured to reflect light from the proximal one of the light sources to an exterior of the light assembly in an opposing direction at least 90 degrees away from a primary emission direction of the light sources.
A method for illuminating a conveyance, comprising:
- attaching a light assembly to the conveyance, comprising at least two aligned directional light sources mounted one behind another and enclosed by an outer light-transmissive cover, wherein a distal one of the light sources occludes light emitted from a proximal one of the light sources, and a reflector interposed between the light sources and supported inside the outer light-transmissive cover by an inner light-transmissive collar that encloses the proximal one of the light sources and the reflector, wherein the reflector has a convex surface facing the proximal one of the light sources configured to reflect light from the proximal one of the light sources to an exterior of the light assembly in an opposing direction at least 90 degrees away from a primary emission direction of the light sources,
- wherein the light assembly is oriented with the light sources facing backwards relative to the conveyance, such that the distal light shines backwards without being reflected and the light from the proximal light source is reflected by the reflector forward.
