Detailed Description

The technical solution of the present invention is further described in detail by the following specific embodiments in combination with the accompanying drawings:

example (b): as shown in fig. 1 and 2, a wall washing lens, including cup 1, the cup includes the top surface, bottom surface 3 and lateral surface, the cup top surface is provided with light-emitting portion 2, the cup bottom surface indent is provided with cavity 4, in use, light source 8 is located under the cavity, light-emitting portion includes middle zone 6 and peripheral zone 7, middle zone and peripheral zone comprise a plurality of bellied unit structures respectively, as shown in fig. 7 and 8, a plurality of bellied unit structure top surfaces are the inclined plane, the cross-section is trapezium structure or triangular structure, the top surface inclination angle of the bellied unit structure of middle zone is greater than the top surface inclination angle of the bellied unit structure of peripheral zone.

The plurality of raised unit structures are arranged in a plurality of rows and are uniformly distributed in parallel.

As shown in fig. 9 and 10, the slope of the top surface of the raised unit structure may be a flat surface or a curved surface.

The inclination angle of the top surface of the unit structure protruding from the middle area is 12-36 degrees. The top surface of the unit structure protruding from the peripheral area has an inclination angle of 3-12 degrees.

The periphery of the light-emitting part is provided with an installation part 9 which is in a solid ring shape. The inner end of the cavity is provided with a convex lens structure 5 protruding downwards.
