Embodiment 1

[0033] Embodiment 1, with reference to Figure 1-8 .

[0034] A plane lens, comprising a transparent mirror body, the transparent mirror body has a bottom surface, a total reflection surface, and an exit surface, the bottom surface is provided with an incident groove for accommodating a light source facing the inner direction of the transparent mirror body, and the incident concave The side wall of the groove is the incident surface.

[0035] As an improvement of the above technical solution, the incident surface includes a small-angle incident surface and a large-angle incident surface.

[0036] As a further improvement of the above technical solution, a transition curved surface is provided between the total reflection surface and the exit surface.

[0037] As a further improvement of the above technical solution, the total reflection surface includes a first total reflection surface and a second total reflection surface.

[0038] As a further improvement of the above tec...

Embodiment 2

[0062] Embodiment 2, with reference to Figure 9-15 .

[0063] This embodiment is basically the same as Embodiment 1, the difference is that this embodiment does not have the second total reflection surface in Embodiment 1.

Abstract

The invention discloses a plane lens and an illuminating lens device based on the plane lens. The plane lens comprises a transparent lens body. The transparent lens body is provided with a bottom face, a total-reflection face and an emergence face. The bottom face is provided with an incidence groove used for containing a light source and faces towards the interior of the transparent lens body. The side wall of the incidence groove serves as an incidence face. According to the improvement of the technical scheme, the incidence face comprises a small-angle incidence face body and a large-angle incidence face body; a transition curved face is arranged between the total-reflection face and the emergence face; the total-reflection face comprises a first total-reflection face body and a second total-reflection face body. The illuminating lens device comprises one or more plane lens. The plane lens and the illuminating lens device based on the plane lens have the advantages, which cannot be achieved by existing products, that the surface smoothness is good, cleaning is convenient, and the light-pervious efficiency is high.

Description

technical field [0001] The invention relates to an optical processing component, in particular to a plane lens and an illumination lens device based on the plane lens. Background technique [0002] As we all know, in lighting fixtures such as street lamps and tunnel lamps, the structure includes a lens for processing light distribution. Due to the need for light distribution, the lenses of existing lamps generally have an approximate structure similar to peanut shells on their surfaces. These structures lead to uneven lens surfaces, which are prone to dirt and dirt during use and are difficult to clean. At the same time, they are also easy to cause lens surface wear and affect the light distribution quality of the lens. In addition, the existing lens has the defect of low light utilization rate. [0003] In view of this, the purpose of the present invention is to provide a new technical solution to solve the existing technical problems. Contents of the invention [0004]...
