Claim of US Patent No. 10,440,796

1. A lighting device comprising:a circuit board having
an upper surface that extends from a first end to a second end,
a lower surface opposite the upper surface, and
opposing sidewalls extending from the upper surface to the lower surface;
a plurality of light-emitting diodes (LEDs) arranged in a single-line linear array along the upper surface of the circuit board,
wherein the plurality of LEDs includes LEDs of at least three different colors; and
a first optical terminator that overhangs over a first outmost LED at the first end of the circuit board such that the first outmost LED is positioned within a tetrahedral cavity of the first optical terminator,
wherein the first optical terminator is configured to redirect light from the first outmost LED along an axis of the linear array.
