Abstract
An LED light source includes an LED die and a transparent encapsulation. The LED die includes a die emitting surface. The transparent encapsulation includes a reflective surface and an encapsulation emitting surface. The LED die is encapsulated by the transparent encapsulation such that the die emitting surface faces the encapsulation emitting surface. The transparent encapsulation is generally convex albeit having a concave recessed portion. The recessed portion is aligned with the die emitting surface and shaped so as to increase an effect of total internal reflection of light rays generated by the light emitting diode die and incident thereon.
