DETAILED DESCRIPTION

[0027] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0028] Example 1

[0029] like Figures 1 to 4 As shown, in order to solve the above technical problems, the utility model provides a light guide mechanism of an atmosphere lamp, including two light guide bars 11 arranged at intervals, a light mixing connection part 13 is connected between the middle positions of the two light guide bars 11, the light emitting surfaces 14 of the two light guide bars 11 are located on the same side, and a plurality of light guide teeth 15 are provided on the side of the two light guide bars 11 away from the light emitting surface 14. Specifically, the two light guide bars 11 and the light mixing connection part 13 are made of the same material, which can be PMMA or PC, and the two light guide bars 11 and the light mixing connection part 13 are integrally formed by injection molding, and the two light guide bars 11 have the same shape and size.

[0030] See attached Figure 5-8Since two light guide bars 11 are provided in the light guide mechanism 1, in actual use, a light-emitting lamp group 2 is installed at least at one end of the light guide mechanism 1. Preferably, light-emitting lamp groups 2 are installed at both ends of the light guide mechanism 1. Two LED lamps are respectively provided corresponding to the two light guide bars in each light guide group 2, that is, a total of four LED lamps are provided. The four LED lamps are respectively connected to a controller, and the light emitted by the four LED lamps is respectively reflected by the two light guide bars 11 and emitted from the light emitting surfaces 14 of the two light guide bars 11. Since the interval between the two light guide bars 11 is small, there is an overlapping area between the two strip lights formed by the two light guide bars 11 on the projection plane 41; and since a light mixing connection part 13 is connected between the two light guide bars 11, a small part of the light in the two light guide bars 11 will be transmitted to the light mixing connection part 13.

[0031] To facilitate the analysis of the role of the light guiding mechanism in the present embodiment, the LED lights at both ends of the first light guiding strip 11 are respectively set as LED light No. 1 and LED light No. 2, and the LED lights at both ends of the second light guiding strip 11 are respectively set as LED light No. 3 and LED light No. 4, and four controllers respectively control the lighting effects of the four LED lights; when the colors of the four LED lights are consistent, the light projected onto the projection plane 41 is a single color, and no gradient color will appear; when the colors of LED lights No. 1-3 are consistent, and the color of LED light No. 4 is different, since the colors of LED lights No. 3 and No. 4 are different, a mixed light effect will appear along the length direction of the second light guiding strip 11, and a mixed light effect will also appear on the mixed light connecting portion 13. Therefore, the first light guiding strip 11 forms a strip light of a single color on the projection plane 41, and the second light guiding strip 11 forms a strip light with a mixed light gradient effect on the projection plane 41. The overlapping area of ​​the two strip lights will also have a mixed light gradient effect, and the mixed light connecting portion 13 will also have a mixed light gradient effect on the projection plane 41 Light with a gradient effect is formed; when the colors of the LED lights at both ends of the first light guide strip 11 are the same, the colors of the LED lights at both ends of the second light guide strip 11 are the same, and the colors of the two light guide strips 11 are inconsistent, no mixed light effect will appear along the length direction of the first and second light guide strips 11, but a mixed light effect will appear in the mixed light connection portion 13. Therefore, the first and second light guide strips 11 form strip lights of a single color on the projection plane 41, and a mixed light gradient effect will appear in the overlapping area of ​​the two strip lights, and the mixed light connection portion 13 will also form light with a gradient effect on the projection plane 41; when the colors of the four LED lights are different, a mixed light effect will appear along the length direction of the first and second light guide strips 11, and a mixed light effect will also appear in the mixed light connection portion 13. Therefore, the first and second light guide strips 11 respectively form strip lights with a mixed light gradient effect on the projection plane 41, and a mixed light gradient effect will also appear in the overlapping area of ​​the two strip lights, and the mixed light connection portion 13 will also form light with a gradient effect on the projection plane 41. Therefore, in actual use, the specific light-emitting conditions of the LED lamp can be controlled by the controller according to actual needs, so that the atmosphere lamp can form light with different effects in the projection plane 41; and the dynamic changes of the LED lamp can also be controlled to achieve dynamic changes in the projection light of the atmosphere lamp on the projection plane 41.

[0032] In the present embodiment, two light guide strips 11 and a light mixing connection part 13 are provided in the light guide mechanism 1. Since the interval between the two light guide strips 11 is small, there is an overlapping area between the two strip lights formed by the two light guide strips 11 on the projection plane 41; and a small part of the light in the two light guide strips 11 will be transmitted to the light mixing connection part 13; therefore, by controlling the specific light emitting conditions of the LED lamps at both ends of the light guide strips, the light projected by the light guide mechanism 1 will show a variety of mixed light gradient effects, thereby making the light effect of the atmosphere lamp rich and varied to meet the different needs of consumers.

[0033] Furthermore, at least one end of the two light guide bars 11 is provided with a plurality of first clamping blocks 16; a middle position of the two light guide bars 11 is provided with a plurality of second clamping blocks 17 on one side away from the light mixing connection portion 13, and the second clamping blocks 17 on the two light guide bars 11 are staggered. There is no light mixing connection portion 13 between the two end positions of the two light guide bars 11, so that the two ends of the two light guide bars 11 are conveniently connected to the light emitting lamp group 2. In this embodiment, by providing the first clamping block 16 at the end of the light guide bar, it is convenient for the light guide bar 11 to be connected to the light emitting lamp group 2 through the first clamping block 16; by providing the second clamping block 17, it is convenient for the light guide mechanism 1 to be connected to the mounting member 3, so as to facilitate the installation of the light guide mechanism 1, and the second clamping blocks 17 on the two light guide bars 11 are staggered, so that the clamping force when the light guide mechanism is clamped to the mounting member 3 is evenly distributed along the length direction of the entire light guide mechanism.

[0034] Furthermore, the two light guide strips 11 are arranged parallel to each other, the cross sections of the two light guide strips 11 are both circular, and the light mixing connecting portion 13 is in the shape of a thin sheet.

[0035] Furthermore, the spacing between adjacent light guide teeth 15 on the two light guide bars 11 decreases from the ends to the middle of the two light guide bars 11. In this embodiment, by decreasing the spacing between adjacent light guide teeth 15 from the ends to the middle of the light guide bar 11, that is, the density of the light guide teeth 15 gradually increases, the light reflection at the middle position of the light guide bar 11 far from the light emitting lamp group 2 at the end is more intense, thereby improving the brightness of the middle part of the light guide bar 11 and ensuring that the light of the light guide bar 11 is uniform as a whole.

Since the interval between the two light guide strips 11 is small, there is an overlapping area between the two strip lights formed by the two light guide strips 11 on the projection plane 41; and a small part of the light in the two light guide strips 11 will be transmitted to the light mixing connection part 13; therefore, by controlling the specific light emission conditions of the LED lamps at both ends of the light guide strips, the light finally projected by the atmosphere lamp will show a variety of mixed light gradient effects, so that the light effect of the atmosphere lamp changes in a variety of ways to meet the different needs of consumers; and the overall structure of the atmosphere lamp in the present embodiment is simple and the cost is low.

[0039] Furthermore, the light-emitting lamp group 2 also includes an installation shell 24, the circuit board 21 is arranged in the installation shell 24, the power cord 22 passes through the installation shell 24 and extends to the outside of the installation shell 24, and the outer surface of the installation shell 24 is respectively connected to two plug sleeves 25 corresponding to the positions of the two LED lamps, and the plug sleeves 25 are connected to the interior of the installation shell 24, and the inner wall of the plug sleeve is provided with a plurality of first clamping grooves that cooperate with the first clamping block 16.

[0040] Furthermore, a mounting member 3 is included, the mounting member 3 includes a light guide mechanism mounting groove 31 and light group mounting portions 32 arranged on both sides of the light guide mechanism mounting groove 31, and the two light guide bars 11 are installed with one side of the light emitting surface 14 relative to the opening of the light guide mechanism mounting groove 31. In this embodiment, by providing the light guide mechanism mounting groove 31 and the light group mounting portion 32, the light guide mechanism 1 and the light group 2 can be stably mounted in the mounting member 3, preventing relative displacement between the light guide mechanism 1 and the light group 2 during use, thereby ensuring the use effect of the atmosphere light.

[0041] Furthermore, both side walls of the light guide mechanism installation groove 31 are provided with a plurality of second clamping grooves or second clamping holes 33 that match the second clamping blocks 17.
