Abstract
A beam collimated light emitting module with a light color mixed chamber includes a light holder, a light source assembly located on the light holder, an optical lens covering the light source assembly, and a reflector. The optical lens includes a first light exit surface, a light entrance surface, and a second light exit surface. The first light exit surface has a round-shaped concave surface formed by recessing the first light exit surface, and the aspheric curvature of the concave surface is gradually decreased in an outward direction away from the center of the optical lens. The reflector surrounds the optical lens. When the light source assembly emits light, the bluish white light and the yellowish white light of the light source assembly are refracted by the concave surface, and next the bluish white light and the yellowish white light are reflected by the reflector.
