1. A lamp, comprising:
- a single emitter structure having a substrate with 25 or more light-emitting diodes (LEDs) arranged thereon and a power rating of 80 Watts or more;
a total-internal-reflection (TIR) lens, the lens including;
an optical body member having a substantially straight interior open channel in a lower portion thereof, the interior open channel having a lower opening for accommodating the single emitter structure;
the optical body member having a step-shaped upper surface defining an increasingly wider cavity extending from an interior portion to an upper opening in of the optical body; and
a plurality of refractive surface regions disposed on the step-shaped upper surface of the optical body; and
a holder having a concave interior surface shaped to accommodate the optical body member and a convex exterior surface, the holder having a first opening disposed to surround the lower opening of the optical body member and a second opening opposite the first opening, wherein the optical body member is insertable into the holder through the second opening, the holder further including;
a plurality of tabs disposed along an inside rim of the holder and configured for radial compression fit with a flange of the lens;
a finger-width sized cut-out; and
three or more support members disposed surrounding the first opening of the holder and configured for centering the optical body member with respect to the single emitter structure.

Abstract
A lamp includes a single emitter structure having a substrate with 25 or more light emitting diodes (LEDs) arranged thereon and a power rating of 80 Watts or more, a total internal reflection (TIR) lens with a plurality of refractive surface regions disposed on the step-shaped upper surface of the optical body, and a holder having a plurality of tabs disposed along an inside rim of the holder and configured for radial compression fit with a flange of the lens, and three or more support members configured for centering the optical body member with respect to the single emitter structure. A low weight ratio of hardener over base resin below 6 is used, for example, between 1.5:1 to 2.5:1.
