Asymmetric total internal reflective (TIR) optic light assembly |
摘要 |
A total internal reflective (TIR) optic light bar of a lighting fixture configured to illuminate an object, such as a two-dimensional planar surface, the optic light bar including a body having a first end portion that extends to a second end portion through an elongated intermediate portion, the body including a light input surface extending between the first and second end portions, a total internal reflective (TIR) surface, and at least one light output surface, where the light output surface is formed as a gradual, continuous curve including a plurality of discrete segments that form a curvilinear surface, and where the TIR surface is composed of one or more of the discrete segments which form the curvilinear light output surface. |

1. A total internal reflective (TIR) optic light bar of a lighting fixture configured to illuminate an object, such as a two-dimensional planar surface, the optic light bar comprising:
a body including a first end portion that extends to a second end portion through an elongated intermediate portion, the body including a light input surface extending from the first end portion to the second end portion, a total internal reflective (TIR) surface, and at least one light output surface; wherein the light output surface is formed as a gradual, continuous curve comprising a plurality of discrete linear segments that form a multifaceted light output surface, wherein the TIR surface is composed of one or more of the discrete segments which form the multifaceted light output surface; and wherein each of the plurality of discrete segments are substantially tangent to adjacent ones of the plurality of discrete segments thereby defining the curvilinear profile. |
