On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0023] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a", "an", and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", and "have" are inclusive and therefore specify the presence of stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0024] Although the terms first, second, etc. may be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. In addition, in the description of this application, unless otherwise clearly specified and limited, the terms "set" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0025] For ease of description, spatial relative terms can be used in the text to describe the relationship of an element or feature relative to another element or feature as shown in the figure, and these relative terms are, for example, "in", "inside", "top", "circumferential", "side", "bottom", etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation in addition to the orientation depicted in the figure.

In addition, the "optical pattern" described in the embodiments of this application is also called optical texture, which is a process that applies a special texture processing method to the surface of an optical element. It can change the optical properties of the element by changing the morphology and reflectivity of the element surface; the application range of the optical texture process is very wide, including solar panels, LED lights, liquid crystal displays, etc.; in the light source structure, by processing the texture on the surface of the luminescent material, the refractive index and diffuse reflection ability of the light can be improved, making the lighting effect of the lamp more uniform and soft.

[0027] like Figure 1 As shown, in order to solve the technical problems that the surface light source of the vehicle atmosphere light is high in cost, the effect presented is average, and the cost performance is low, the embodiment of the present application proposes a vehicle atmosphere light and a vehicle having the same, so as to achieve a painting effect with the surface light source, increase the look and feel and playability of the atmosphere light, and improve the cost performance.
