LINEAR FRESNEL OPTIC FOR REDUCING ANGULAR SPREAD OF LIGHT FROM LED ARRAY |
| 摘要 |
A light source may comprise a cylindrical lens, for example a cylindrical Fresnel lens, a linear array of light-emitting elements, the linear array aligned with and emitting light through the cylindrical Fresnel lens, wherein the cylindrical Fresnel lens reduces the angular spread of light in a widthwise axis of the linear array, the linear array spanning a lens length. |
