Power light emitting die package with reflecting lens and the method of making the same
First Claim
1. A light emitting die package comprising:
- a leadframe comprising a plurality of leads, said leadframe having a top side and a bottom side, and a portion of said leadframe defining a mounting pad;
at least one light emitting device mounted on the mounting pad;
a molded body integrated with portions of said leadframe, said molded body defining an opening on the top side of said leadframe, the opening surrounding the mounting pad;
said molded body comprising latches suitable for coupling a heatsink on the bottom side of said leadframe; and
a lens coupled to the molded body, wherein a lower portion of the lens extends downward along angled sides of the opening toward said leadframe so that a portion of said lens is even with or below a top surface of said light emitting device;
wherein said lens terminates above said leadframe to form a gap between the top side of said leadframe and said lens.

Abstract
A light emitting die package and a method of manufacturing the die package are disclosed. The die package includes a leadframe, at least one light emitting device (LED), a molded body, and a lens. The leadframe includes a plurality of leads and has a top side and a bottom side. A portion of the leadframe defines a mounting pad. The LED device is mounted on the mounting pad. The molded body is integrated with portions of the leadframe and defines an opening on the top side of the leadframe, the opening surrounding the mounting pad. The molded body further includes latches on the bottom side of the leadframe. The lens is coupled to the molded body. A composite lens is used as both reflector and imaging tool to collect and direct light emitted by LED(s) for desired spectral and luminous performance.
