Problems solved by technology

At the same time, since the effective light-emitting surface is only the top of the lens, the area of ​​the light-emitting surface is relatively small, so the surface of the lens is very bright, and the direct glare is very serious.

Embodiment Construction

[0025] The following detailed description of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0026] The structure of the lens 1 of the present application, such as figure 2 As shown, the lens 1 is a stretching lens, image 3 The cross section is stretched in line straight. The lens 1 includes a bottom surface 101, and the bottom surface 101 is formed into a light receiving chamber 102 by a depression, which can be used to accommodate the light source. The enample cavity 42 includes a first incident surface 1021, a second incident surface 1022, a third into the optical surface 1023. Wherein, the first incident surface 1021, the third entrance surface 1023 is connected to the plane and the bottom surface 101, respectively. The second incident surface 1022 is a curved surface protruding from the lens 1, and the curved surface may be a circular arc surface or a free surface. In other preferred embodiments, the inf...

Abstract

The invention provides a lens, an optical system and a lamp. The lens comprises a bottom face, the bottom face is concaved inwards to form a light inlet cavity, the light inlet cavity is used for containing a light source, a first light outlet face, a second light outlet face, a third light outlet face and a reflecting face which are sequentially connected are arranged above the lens, a first part of light emitted by the light source enters the light inlet cavity to be refracted for the first time, and a second part of light emitted by the light source enters the light outlet cavity to be refracted for the second time. The light is refracted for the second time on the first light-emitting surface and then is emitted; a second part of light emitted by the light source enters the light inlet cavity to be refracted for the first time, and is refracted for the second time on the second light outlet surface to be emitted; and a third part of light emitted by the light source enters the light inlet cavity to be refracted for the first time, is reflected by the reflecting surface, is refracted for the second time on the third light outlet surface and then is emitted, and each part of light is deflected towards the same side after being emitted. All light rays are divided into three parts by the lens, and the three parts illuminate different areas of a light receiving surface after being emitted, so that the wall washing effect is more uniform.

Description

Technical field [0001] The present invention relates to a lens, particularly a large angular lens for a luminaire, and an optical system and a lamp including the lens. Background technique [0002] When designing the light, it is often necessary to achieve a polarizing effect by a lens. The existing polarizing lens is mostly a polarizing scheme similar to the TIR lens, such as figure 1 Indicated. The TIR lens control method is that the side of the lens is a total reflecting surface, and the light is reflected from the front of the lens, and the light light is irritated by the asymmetric offset light of the light surface, and the light light is irradiated onto the wall. Since there is no exit light on the side of the lens, all light is exit from the front of the lens so that the dark area will appear in the area near the bottom of the wall, and this dark zone will be the distance between the lamp and the front horizontal distance. At the same time, since the effective light surfac...
