Core Points：
1,The energy in the total reflection surface need precise control, transition evenly, to avoid the sudden part of the light exit angle is too large or too small, hit the hood to form stray light;
2, In accordance with ratio the lens aperture and the hood length of 1: 1 to set the hood, when the theory of design basically no light hit the hood; The actual product will have a small amount of light hitting the hood, but does not form a clear bright ring outside the spot, it will only produce a transition of the side spots;
3, Using Calculus structure reasonably, makes the surface of the light evenly, and the spot is uniform and soft, This structure does not allow more light to pass through the microstructure and hit the lens hood.
