Abstract:
1. A light-emitting module comprising: a substrate including a thermally conductive portion and an interconnect pattern which are formed on a flat surface in the same plane; at least one light-emitting element thermally connected to the thermally conductive portion by solder, electrically connected to the interconnect pattern, and configured to generate heat while emitting light; a light distribution control member formed separately from the substrate, the light distribution control member comprising at least one cup corresponding to each of the at least one light-emitting elements, each of the at least one cup comprising a concave portion having a curved surface; a peripheral edge portion located on an incident side with respect to the at least one light-emitting element and extending parallel to an axis of light emission and connected to the concave portion at a discontinuity located farther from the substrate than a top of the at least one light-emitting element between the curved surface of the concave portion and the peripheral edge portion and thermally connected to the thermally conductive portion at a periphery of the light-emitting element by an adhesive; and a ridge portion formed on an exit side configured to project light emitted from the light-emitting element; the light distribution control member configured to control distribution of the light emitted from the light-emitting element; and a cover thermally connected to the ridge portion and configured to pass therethrough the light emitted from the light-emitting element.
