Abstract
A light emitting diode (LED) light source is disclosed. The LED light source comprises a lens structure that includes a hemispherical dome with a base. The LED light source comprises a cavity in the base. The cavity has an opening and a taper such that a cross-section area within the cavity is smaller than an area of the opening. The LED light source comprises a light emitting device comprising an LED die contacting the taper. The taper allows for easy insertion of the LED die into the lens structure. The taper serves to accurately align the LED die when the LED die is inserted.
