Abstract
Description
Technical Field
[0001] The present application relates to the field of lens technology, and more specifically, to an all-in-one lens and a lamp with a reflective structure. Background Art
[0002] A lens is an optical element made of transparent material (such as glass, crystal, etc.). Convex lens: thick in the middle and thin at the edges, there are three types: biconvex, plano-convex, and concave-convex; concave lens: thin in the middle and thick at the edges, there are three types: biconcave, plano-concave, and convex-concave. Lenses play an important role in astronomy, military, transportation, medicine, art and other fields. Lenses are made according to the law of light refraction. A lens is a refractor whose refractive surface is a transparent body consisting of two spherical surfaces (part of a spherical surface), or a spherical surface (part of a spherical surface) and a plane. The images it forms are both real and virtual. The glass or plastic components on the lamp can change the direction of light or control the light distribution.
[0003] The existing lens structure is complex, which makes it inconvenient to use and cannot better control the light emission range and angle, increasing the light dispersion on the reflective surface, and cannot fully utilize the light emitted by the light source, resulting in glare in some occasions. Discomfort glare: From the literal meaning, it can be understood that this type of glare will only make the vision uncomfortable or distract attention. But it will not have a significant impact on vision or eyesight in a short period of time.
[0004] In order to solve the above problems, the present application provides an all-in-one lens and lamp with a reflective structure. Utility Model Content
[0005] The present application provides an all-in-one lens and a lamp with a reflective structure using the following technical solutions:
[0006] A multi-in-one lens and lamp with a reflective structure, comprising at least one lens, wherein a cavity is provided at the inner bottom of the lens, an incident surface is provided at the inner wall of the cavity, a reflective surface is provided at one side of the outer wall of the long side of the lens, and a light source is provided at the bottom of the cavity.
[0007] Furthermore, the lens is an elliptical structure. When the lens is an elliptical structure, the reflecting surface is located at the bottom of one side of the long side of the elliptical structure. The reflecting surface is a long straight line wave shape, and the length of the reflecting surface is greater than the length of the short side of the elliptical structure. At this time, the refraction shape of the light source is a fan shape.
[0008] Furthermore, the lens has an arc circular structure, and when the lens is an arc circular structure, the reflecting surface is located at the bottom of one side of the short side of the arc circular structure, the reflecting surface is a short straight wave shape, and the curvature of the reflecting surface is smaller than the curvature of the long side. At this time, the refraction shape of the light source is a regular fan shape.
[0009] Furthermore, the lens is a circular structure. When the lens is a circular structure, the reflective surface is located at the bottom of the side wall of the circular structure. The reflective surface is annular and wavy, and the reflective surface surrounds the bottom of the outer wall of the lens. At this time, the refraction shape of the light source is away from the lens annular circle.
[0010] Furthermore, the reflecting surface is a cut surface of the bottom of the outer wall of the lens, and the reflecting surface can be a straight surface, an inclined surface or a curved surface, and the reflecting surface can be partially cut or fully cut, and a plurality of the lenses are distributed in an array.
[0011] Furthermore, a lamp includes the all-in-one lens with a reflective structure.
[0012] In summary, this application includes the following beneficial technical effects:
[0013] By adjusting the different illumination distribution of the light source and matching the reflection surfaces with different section angles and lengths to reflect the light, we can avoid glare caused by direct illumination of the human eyes, reduce the white light and dispersion caused by direct illumination of the eyes, increase the artificial safety of the lamp during re-illumination, and greatly increase the applicability of the lamp by matching with lenses of different shapes.

[0025] Example:
[0026] The present application discloses an all-in-one lens and a lamp with a reflective structure. Figure 1-Figure 6 , comprising at least one lens 1, a cavity 2 is provided at the inner bottom of the lens 1, an incident surface 3 is provided on the inner wall of the cavity 2, a reflecting surface 4 is provided on one side of the outer wall of the long side of the lens 1, and a light source 5 is provided at the bottom of the cavity 2.
[0027] Example 1: This application example discloses an all-in-one lens and a lamp with a reflective structure, please refer to Figure 1 The lens 1 is an elliptical structure. When the lens 1 is an elliptical structure, the reflecting surface 4 is located at the bottom of one side of the long side of the elliptical structure. The reflecting surface 4 is a long straight wave shape, and the length of the reflecting surface 4 is greater than the length of the short side of the elliptical structure. At this time, the refraction shape of the light source 5 is a fan shape. The reflecting surface 4 as a long straight line can control the range of its light output to be an irregular fan shape with a large range. When one side of the reflecting surface 4 is installed, it faces the side where people often stay. It can be suitable for indoor large-area space lighting. The refracted light is reflected on the wall through the reflecting surface 4 instead of directly irradiating the human eye.
[0028] Example 2: This application example discloses an all-in-one lens and a lamp with a reflective structure, please refer to Figure 2 The lens 1 is an arc circular structure. When the lens 1 is an arc circular structure, the reflecting surface 4 is located at the bottom of the short side of the arc circular structure. The reflecting surface 4 is a short straight line wavy shape, and the curvature of the reflecting surface 4 is smaller than the curvature of the long side. At this time, the refraction shape of the light source 5 is a regular fan shape. The reflecting surface 4 which is a short straight line can control its light output range to be a fan-shaped range, which is suitable for lighting of small areas indoors.
[0029] Example 3: This application example discloses an all-in-one lens and a lamp with a reflective structure, please refer to Figure 3 The lens 1 is a circular structure. When the lens is a circular structure, the reflecting surface 4 is located at the bottom of the side wall of the circular structure. The reflecting surface 4 is annular and wavy, and the reflecting surface 4 surrounds the bottom of the outer wall of the lens 1. At this time, the refraction shape of the light source 5 is circular away from the lens 1. The ring-shaped reflecting surface 4 can control the light output range to be a small circle, which is suitable for open outdoor lighting.
[0030] See also Figure 1-3 The reflecting surface 4 is a cut surface at the bottom of the outer wall of the lens 1. The reflecting surface 4 can be a straight surface, an inclined surface or a curved surface. The reflecting surface 4 can be partially cut or fully cut. Several lenses 1 are distributed in an array. The reflection angle of the light can be changed through different straight surfaces, inclined surfaces or curved surfaces and the illumination intensity can be adjusted.
[0031] A lamp, characterized in that it comprises a multi-in-one lens with a reflective structure, and the lamp is composed of a lens 1 that is not reflective.
[0032] The implementation principle of this embodiment is: the scene is illuminated by the light source 5 in the cavity 2, and the lighting effect is increased by diffusing and refracting through the incident surface 3, and the reflective surface 4 reflects the light refracted from the incident surface 3, thereby reducing the escape of light.
[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
