Abstract
An optical module includes a light source and a reflective substrate. A first optical medium is disposed such that the first optical medium in combination with the reflective substrate substantially envelops the light source. A second optical medium is disposed to contact the first optical medium, defining a boundary therebetween. Reflective sidewalls bound a lateral portion of the second optical medium. A lens has a lower surface in contact with the second optical medium and spaced from the first optical medium. Light from the source passing through the lens follows a first and a second optical path, the first including refraction at the boundary followed by refraction at the lens; and the second including refraction at the boundary followed by reflection from a sidewall followed by refraction at the lens. An alternative embodiment uses the reflective sidewalls to bound the first optical medium, and the second path differs.
