Abstract:
The invention relates to a pharos cell and the application, belonging to the design technical field for 3-D optical system of LED light source without rotational symmetry. It is characterized in that the cell contains pharos lens; the internal surface of said pharos lens is the side alignment surface which compresses light to a certain angle along the X direction and the external surface of said pharos lens is the even light surface where light intensity is distributed evenly in the other given angle in YZ plane; said X, Y and Z are three orthogonal axes in space respectively. The invention can make light emitted by LED light source align to the given angle on a direction and make light intensity be distributed evenly in the given angle on the vertical direction. It is very appropriately fit for optical system, for example, pharos, which requires high demands for side alignment and light intensity control.
