Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-5, a fish scale light mixing lens includes a light condensing portion 1 and a reflection portion 2, the light condensing portion 1 is disposed in a central area of the lens, the reflection portion 2 is disposed at an outer edge of the light condensing portion 1, and when a light source such as an LED is located at a focal position of the fish scale light mixing lens of the present application, light rays having a small included angle with an optical axis of the fish scale light mixing lens will be irradiated on the light condensing portion 1 and condensed by the light condensing portion 1; and the light ray with a larger included angle with the optical axis will irradiate on the reflecting part 2 and be emitted from the top of the lens of the application after being reflected by the reflecting part 2.

Preferably, the cross section of the reflection portion 2 is annularly arranged, the light-gathering portion 1 is installed at the center of the reflection portion 2, the upper end of the light-gathering portion 1 is formed with an upper light-emitting surface 11, the upper surface of the reflection portion 2 is formed with an upper light-emitting surface 22, the upper light-emitting surface 22 is connected with the upper light-emitting surface 11 and forms a light-emitting surface, the included angle between the upper light-emitting surface 22 and the upper light-emitting surface 11 is an acute angle, so that light can be mixed after being emitted from the upper light-emitting surface 22 and the upper light-emitting surface 11, and the light can be more uniformly mixed, meanwhile, the lower surface of the light-gathering portion 1 is formed with a lower light-entering surface 12, an inner light-entering surface 23 is formed inside the reflection portion 2, the lower light-entering surface 12 is connected with the inner light-entering surface 23 and forms a mounting groove for mounting a light source, the, reducing the spread of light.

In addition, because the outside plane of reflection 2 21 is the scale 211 face of compriseing a plurality of scales 211, the scale 211 face is formed by a plurality of fish scale scales 211 along the surface from the top down successive layer arrangement of reflection 2, scale 211 is the ichthyoid setting, the vertical cross-section of scale 211 is the curved surface, the light that is the ichthyoid scale 211 can shine to outside plane of reflection 21 falls into the multi-angle, and reflect to the upside and go out light face 22, with evenly shine on the object, avoid light too concentrated, it is effectual to mix the light, and simultaneously, because the vertical cross-section of scale 211 is the curved surface, can reduce the reflection angle when light is reflected by scale 211, the angle is too big when avoiding light to be reflected to upside light face 22 by scale 211, lead to light too dispersed, influence illuminating effect.
