Abstract
In one aspect, an illumination source includes a socket formed by the union of a sub-assembly platform and a light-guide element, and a discrete light source received in the socket. In another aspect, the light-guide element includes a concentration region proximate an in-coupling region opposite an out-coupling region, the concentration region directing multidirectional light from the in-coupling region toward the out-coupling region.

20. A light-guide element comprising:
-
an in-coupling region for receiving multidirectional light from a light source; an out-coupling region for emitting light from the light-guide element; and a concentration region proximate the in-coupling region opposite the out-coupling region, the concentration region directing multidirectional light from the in-coupling region toward the out-coupling region. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)

- 30. A light-guide element comprising an in-coupling region, a propagation region, an out-coupling region, a top surface, and a sidewall, wherein (i) light is received by the light-guide element at the in-coupling region, transmitted through the propagation region, and emitted by the out-coupling region, and (ii) the top surface and the sidewall are joined by a rounded corner, (iii) the top surface and the sidewall reflect light incident thereon, and (iv) the rounded corner transmits light incident thereon.
- 33. A light-guide element comprising an in-coupling region, a propagation region, an out-coupling region, a top surface, and a sidewall, wherein (i) light is received by the light-guide element at the in-coupling region, transmitted through the propagation region, and emitted by the out-coupling region, (ii) the top surface and the sidewall are joined by a 90-degree corner, and (iii) the top surface, sidewall, and 90-degree corner reflect light incident thereon.
