Tilted emission LED array
First Claim
1. A light emitting diode (LED) component system comprising:
- a housing;
a plurality of LED components within the housing, such that light emitted from the housing comprises a peak emission shifted from a perpendicular centerline of the housing;
each of the plurality of LED components comprising;
at least one LED chip on a mounting surface; and
a primary optical lens on the at least one LED chip and comprising a lens base attached to the mounting surface such that the at least one LED chip and the lens base are aligned along the same plane, wherein the at least one LED chip is displaced in relation to the centerline of said lens base wherein the average peak emission of said at least one LED chip is shifted from a perpendicular centerline of the lens base.

Abstract
The present disclosure is directed to LED components, and systems using such components, having a light emission profile that may be controlled independently of the lens shape by varying the position and/or orientation of LED chips with respect to one or both of an overlying lens and the surface of the component. For example, the optical centers of the LED emitting surface and the lens, which are normally aligned, may be offset from each other to generate a controlled and predictable emission profile. The LED chips may be positioned to provide a peak emission shifted from a perpendicular centerline of the lens base. The use of offset emitters allows for LED components with shifted or tilted emission patterns, without causing output at high angles of the components. This is beneficial as it allows a lighting system to have tilted emission from the LED component and primary optics.
