1. A luminaire comprising:

  • a substrate; and

    an array of a number of light sources mounted to the substrate such that each light source is pointing in a same direction, each light source comprising;

    a light emitting diode that has an axis; and

    an optic that receives light from the light emitting diode and directs the received light to produce an illumination pattern that has a first intensity, wherein the optic comprises an inner hemispherical surface, the optic is symmetric with respect to a first reference plane passing through the axis, and the optic comprises a reflecting feature on a first side of a second reference plane, the second reference plane perpendicular to the first reference plane, wherein the reflecting feature reflects a portion of the light toward a second side of the second reference plane that is opposite the first side of the second reference plane,wherein the array of the number of light sources produces a scaled version of the illumination pattern with a second intensity that substantially equals to the first intensity multiplied by the number.
