[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0041] Embodiment one:

[0042] The embodiment provides an atmosphere lamp 01, which is used for being installed on a console 02, and is in a long strip shape as a whole, as shown in the figure, comprising a wrapping piece 012, a light guide strip 013, a light source 011, a light processing layer 014 and a protective cover 015. Figure 1

[0043] As shown in the figure, the inner side of the wrapping piece 012 is a hollow structure, and the upper side is an open structure, and the material is a plastic material. Figure 1

[0044] The light guide strip 013 is arranged on the inner side of the wrapping piece 012.

[0045] Specifically, the light guide strip 013 is fixedly connected to the bottom wall on the inner side of the wrapping piece 012; the inner bottom of the light guide strip 013 is formed with a plurality of evenly distributed dot structures 0131; the number of the dot structures 0131 can be adjusted according to the specific implementation environment, and is not limited here; the dot structures 0131 are used for causing the light to occur diffuse reflection.

[0046] At least one light source 011 is arranged on the inner side of the wrapping piece 012, and the light source 011 is located at the side of the light guide strip 013.

[0047] Specifically, two light sources 011 are arranged in the embodiment, and the two light sources 011 are fixedly connected to the two side walls on the inner side of the wrapping piece 012, and the two light sources 011 are located on the left and right sides of the light guide strip 013; in other embodiments, one light source 011 can also be arranged, and the light source 011 is located on one side of the light guide strip 013; it is worth noting that the light source 011 is an LED lamp. Figure 3 ​​As shown, in the left-right direction of the vehicle, the light emitted by the light source 011 is incident into the light guide strip 013. Since the light emitting surface of the light source 011 and the light incident surface of the light guide strip 013 have almost no gap, the refraction and reflection of the light on the light guide plate light incident surface can be ignored. The light emitted upward by the light source 011 is directly incident onto the upper surface of the light guide strip 013 and then refracted and emitted out of the light guide strip 013. The light deflected downward is incident onto the inner lower surface of the light guide strip 013. The inner lower surface of the light guide strip 013 is unevenly distributed with the dot structure 0131. The light incident onto the dot structure 0131 will be diffusely reflected. The reflected light is incident onto the upper surface of the light guide strip 013 and then refracted and emitted out of the light guide strip 013. The light emitted from the upper surface of the light guide strip 013 is emitted out of the atmosphere lamp 01 through the light processing layer 014 and the protective cover 015. The light processing layer 014 does not block the incident light in this direction. For example Figure 3 As shown, the light emitting angle θ of the atmosphere lamp 01 is close to 90° in the left-right direction of the vehicle. Further, the dot structure 0131 is more densely distributed the farther it is from the light source 011. The layout of the dot structure 0131 can achieve the effect of uniform emission of light from the entire light guide strip 013, thereby ensuring the uniformity of the overall light emission of the atmosphere lamp 01.

[0048] The light processing layer 014 is arranged on the upper side of the light guide strip 013, and the light processing layer 014 is located on the inner side of the wrapping member 012.

[0049] Specifically, the light processing layer 014 is fixedly connected to the upper side of the light guide strip 013. In this embodiment, as shown in Figure 2 The light processing layer 014 includes, from bottom to top, a substrate layer 0141, an intermediate microstructure layer 0142, and a protective layer 0143. It is worth noting that the substrate layer 0141 is made of transparent PET material, has a thickness of 200 μm, and serves to support the film and prevent the intermediate microstructure layer 0142 from being bent and damaged. The intermediate microstructure layer 0142 has a thickness of 10 μm and is uniformly distributed with inverted trapezoidal microstructures 01421. The microstructures completely absorb light, and the light can only pass through the gaps between adjacent microstructures 01421. The upper protective layer 0143 has a thickness of 50 μm and prevents small particles in the air from entering the intermediate microstructure layer 0142 and affecting the function of the light processing layer 014. Further, as shown in Figure 4 In the front-rear direction of the vehicle, the light reflected by the dot structure 0131 of the light guide strip 013 is incident onto the upper surface of the light guide strip 013 and then refracted and emitted out of the light guide strip 013. Since the vertical angle of the light incident into the light processing layer 014 is large, the light is directly absorbed by the microstructures 01421 of the light processing layer 014. The light with a small vertical angle can pass through the gaps between adjacent microstructures 01421 and then be emitted out of the atmosphere lamp 01 through the protective cover 015.

[0050] The light emitting angle θ2 of the atmosphere lamp 01, which is related to the gap between the microstructure 01421, can be described as follows: as Figure 5 The height H1 of the microstructure 01421 of the light processing layer 014 is consistent with the thickness of the microstructure layer of the light processing layer 014, and the microstructure 01421 is not visible to the naked eye, and the width needs to be less than 1 μm; the relationship between the light emitting angle θ2 of the atmosphere lamp 01 and the gap L1 and L2 of the microstructure is:

[0051]

[0052] The protective cover 015 is arranged at the opening of the wrapping piece 012,

[0053] In this embodiment, the protective cover 015 is fixedly connected at the opening of the wrapping piece 012, and the protective cover 015 is located on the upper side of the light processing layer 014, and the containing cavity is formed by the protective cover 015 and the wrapping piece 012, and the light guide strip 013, the light source 011 and the light processing layer 014 are located in the containing cavity; the light emitted by the light source 011 is guided by the light guide strip 013, and then the light is emitted to the outside through the light processing layer 014 and the protective cover 015.

[0054] Embodiment two:

[0055] Firstly, referring to Figure 6 The front and rear directions in the vehicle, the light emitting angle of the traditional automobile atmosphere lamp 01 embedded in the instrument table 02 is 90°, and the light is reflected into the human eye through the front windshield 03, at this time the front windshield 03 is similar to a plane mirror, and the virtual image light band formed by the reverse extension line of the reflected light is in the driver's straight ahead, which affects the normal driving of the driver.

[0056] Therefore, referring to Figure 7 and Figure 8 , the embodiment provides a mounting method of the atmosphere lamp 01, the atmosphere lamp 01 is the atmosphere lamp 01 in the embodiment one, and the atmosphere lamp 01 is mounted on the instrument table 02 of the automobile. The mounting method comprises the following steps:

[0057] Obtaining the light emitting angle of the atmosphere lamp 01;

[0058] Specifically, in the step of obtaining the light emitting angle of the atmosphere lamp 01, the light emitting angle θ2 is obtained by the following formula:

[0059]

[0060] Wherein, L1 is the upper gap between the two microstructures 01421; L2 is the lower gap between the two microstructures 01421; and H1 is the height of the microstructure 01421.

[0061] According to the light emitting angle, the installation position of the ambient light 01 is determined so that the light emitting angle is less than the included angle of the ambient light 01 and the connection of the roof 04 and the windshield 03.

[0062] Specifically, in the step of determining the installation position of the ambient light 01 according to the light emitting angle so that the light emitting angle is less than the included angle of the ambient light 01 and the connection of the roof 04 and the windshield 03, the included angle θ1 of the connection of the roof 04 and the windshield 03 is obtained by the following formula:

[0063]

[0064] Wherein, L is the length of the ambient light 01 from the connection of the roof 04 and the windshield 03; H2 is the height of the ambient light 01 from the connection of the roof 04 and the windshield 03; α is the installation inclination angle of the ambient light 01.

[0065] As described above, as shown in Figure 7 and Figure 8 The light emitting angle of the ambient light 01 of embodiment one embedded in the instrument table 02 in the front-rear direction of the vehicle is θ2, when the light emitting angle θ2 is less than the included angle θ1 of the ambient light 01 and the connection of the roof 04 and the windshield 03, that is, all the light emitted by the ambient light 01 will not be projected onto the front windshield 03, at this time, no reflected light enters the naked eye of the driver, which will not affect the normal driving of the driver;

[0066] The included angle θ1 is related to the installation position of the ambient light 01, that is, the length L and the height H2 of the ambient light 01 from the connection of the roof 04 and the windshield 03, and the installation inclination angle α; the relationship expression is as follows:

[0067] θ1=90°+β-α

[0068] Wherein:

[0069] When θ1<θ2, the gap L1, L2 between the microstructures 01421 of the light processing layer 014, the length L and the height H2 of the ambient light 01 from the connection of the roof 04 and the windshield 03, and the installation inclination angle α satisfy the following relationship:

[0070]

[0071] Therefore, the problem that the ambient light 01 affects the driving of the driver can be solved.

[0072] In the description of the present specification, the description of the terms "one embodiment", "some embodiments", "an example", "a specific example", or "some examples" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0073] The above-described embodiments only express several implementation manners of the present application, which are described in a more specific and detailed manner, but cannot be understood as a limitation on the patent scope of the present application. It should be noted that, for those of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present application, which are all within the protection scope of the present application.
