AI Technical Summary
Technical Problem
Existing wall washer lights have uneven light distribution when illuminating, which affects the aesthetics and has low luminous efficiency. They cannot achieve uniform illumination by their own structure alone.
Method used
Design a lens whose optical axis is parallel to the optical axis of the light source and has an irregular structure. Through a combination of total internal reflection and direct illumination, light is made to undergo total internal reflection and convergence within the lens before being emitted, thus achieving uniform illumination.
Benefits of technology
It achieves uniform wall brightness, improves light efficiency, and eliminates the need for additional structures such as lampshades, ensuring high light efficiency and uniform lighting effects.

Abstract
The optical axis of the lens is parallel to the optical axis of a light source, the lens is provided with an installation face used for installation, the installation face is provided with a light source groove used for containing the light source, and the peripheral wall and the bottom face of the light source groove form an incident face of the lens. The lens is provided with a special-shaped structure located at the far end of the emitting direction of the light source, and the special-shaped structure is provided with an emergent face allowing light to be emitted out. Wherein the special-shaped structure is configured to be matched with light rays incident through the incident surface to complete total reflection and direct incidence in the special-shaped structure, and then the light rays are emitted through the emergent surface. By designing the lens with the special-shaped structure, the light originally facing the direction away from the wall surface is totally reflected and then is emitted through the emergent surface, and the light and the light directly irradiating the emergent surface are emitted to the far end of the wall surface, so that the convergence of the light with a relatively large incident angle is completed, the light emitted by the first emergent surface is more, the illumination brightness is higher, and the illumination effect is better. The emergent light can uniformly irradiate the wall surface only by means of the self structure without depending on a lampshade.
