ABSTRACT:
An optical adjusting apparatus having a composite pattern structure is described. The optical adjusting apparatus include a substrate layer, at least one first pattern module and at least one second pattern module. The substrate has a first optical surface and a second optical surface opposite to the first optical surface. The first pattern module positioned on the first optical surface, wherein the first pattern module has a first structure unit along a first arrangement direction. The second pattern module which is adjacent to the first pattern module and positioned on the first optical surface. The second pattern module has the second structure unit along a second arrangement direction. The first structure unit of the first pattern module is connected to the second structure unit of the second pattern module. Therefore, the convergent angle of a light module is adjusted and the brightness of the light module is increased along specific direction.
