Abstract
An edge-lit light engine module for signs and a sign are provided. The light engine module has housing and a light engine that fits within the housing. The housing has a base member and at least one side member that overlaps a tab formed along an edge of a sign face. The housing is configured to align the light engine with the partial edge of the sign so that light from the light engine enters and is reflected within the material that forms the sign face so that the sign face becomes illuminated. The housing properly aligns the light engine, and also serves as a heat sink to draw heat away from the light engine and transfer the heat outside the housing.
