[0053] In order to make the purpose, technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in conjunction with the drawings.

[0054] The following description refers to the accompanying drawings. Unless otherwise indicated, same or similar elements in different drawings are denoted by same or similar reference numerals. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0055] With the development of vehicle lamp technology, more and more attention is paid to the design of dynamic lighting patterns with diversity. In the related art, in order to achieve a dynamic display effect, a plurality of light emitting lamps are usually designed, and a plurality of light collectors corresponding to the plurality of light emitting lamps are designed on the thick wall. As the size of the light emitting surface is compressed smaller and smaller, in order to adapt the plurality of light emitting lamps, the plurality of light collectors and the smaller and smaller light emitting surface, the spacing between the light emitting lamps becomes smaller and smaller, which causes serious heat dissipation problems.

[0056] To this end, the light emitting structure according to the embodiments of the present application is designed with two light emitting groups, and the first light emitted by one of the light emitting groups is condensed by the light collecting part in the thick-wall light guide body, and the second light emitted by the other light emitting group is condensed by the reflective light collector, that is, the first light and the second light are condensed by different light collecting structures, compared with the related art in which all the light emitted by the light emitting lamps is condensed by the light collecting part in the thick-wall light guide body, the first light emitting lamps in the first light emitting group and the second light emitting lamps in the second light emitting group can be arranged more dispersedly, which is beneficial to heat dissipation.

[0057] Specifically, referring to Figures 1 to 9 The light emitting structure 1 according to the embodiments of the present application comprises a light emitting member 10, a thick-wall light guide body 20 and a reflective light collector 30.

[0058] The light emitting member 10 comprises a first light emitting group 11, a second light emitting group 12 and a circuit board 13, the first light emitting group 11 and the second light emitting group 12 are mounted on the same side of the circuit board 13 and are electrically connected to the circuit board 13, the first light emitting group 11 comprises first light emitting lamps 111, the second light emitting group 12 comprises second light emitting lamps 121, and the first light emitting group 11 and the second light emitting group 12 have different light functions. The thick-wall light guide body 20 comprises a main body part 21 and a light collecting part 22 connected to each other, the light collecting part 22 is located on the light emitting side of the first light emitting group 11 and is arranged corresponding to the first light emitting group 11, for receiving the first light emitted by the first light emitting group 11 and transmitting to the main body part 21. The reflective light collector 30 is located on the light emitting side of the second light emitting group 12 and is arranged corresponding to the second light emitting group 12, for receiving the second light emitted by the second light emitting group 12 and transmitting to the main body part 21.

[0059] The above design that the first light emitting group 11 and the second light emitting group 12 have different light functions, wherein the light function can include at least one of the light emitting color and the light emitting brightness; in this way, the lighting effect when the first light emitting group 11 is lit is different from the lighting effect when the second light emitting group 12 is lit, and the dynamic display effect of the light emitting structure 1 can be realized.

[0060] For example, the first light emitting group 11 and the second light emitting group 12 having different light emitting colors can be that the first light emitting group 11 emits red light when lit, and the second light emitting group 12 emits yellow light when lit. For example, the first light emitting group 11 and the second light emitting group 12 having different light emitting brightnesses can be that the light brightness when the first light emitting group 11 is lit is higher than the light brightness when the second light emitting group 12 is lit.

[0061] The above design that the first light emitting group 11 and the second light emitting group 12 are mounted on the same side of the circuit board 13 and are electrically connected to the circuit board 13 can improve the integration of the circuit board 13, reduce the number of circuit boards used, and reduce the welding process between the circuit boards on the basis of realizing the dynamic display effect of the light emitting structure 1.

[0062] The first light emitted by the first light emitting group 11 is condensed via the light condensing part 22 in the thick-wall light guide body 20, and the second light emitted by the second light emitting group 12 is condensed via the reflective light condenser 30, that is, the first light and the second light are condensed via different light condensing structures, compared with the related art in which all the light emitted by the light emitting lamps is condensed via the light condensing part in the thick-wall light guide body, the first light emitting lamps 111 in the first light emitting group 11 and the second light emitting lamps 121 in the second light emitting group 12 can be arranged more dispersedly, which is beneficial to heat dissipation.

[0063] Next, referring to Figure 2 , the light emitting member 10 will be described in detail.

[0064] The first light emitting group 11 and the second light emitting group 12 are distributed along the first direction x, which realizes the dispersion of the first light emitting group 11 and the second light emitting group 12 along the first direction x, which is beneficial to heat dissipation.

[0065] In some embodiments, the interval between the first light emitting group 11 and the second light emitting group 12 along the first direction x is greater than or equal to 5 mm. By reasonably limiting the interval between the first light emitting group 11 and the second light emitting group 12 along the first direction x, it can be ensured that the interval between the first light emitting group 11 and the second light emitting group 12 is sufficient, which is beneficial to heat dissipation. Alternatively, the interval between the first light emitting group 11 and the second light emitting group 12 along the first direction x can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc.

[0066] The first light emitting group 11 includes at least two first light emitting lamps 111 distributed along the second direction y. It can be understood that for the same light emitting surface 212, the more the number of first light emitting lamps 111, the more beneficial to realize brighter overall lighting effect and reduce dark areas.

[0067] In some embodiments, the first light emitting group 11 includes at least three first light emitting lamps 111 distributed along the second direction y at equal intervals, so that when all the first light emitting lamps 111 are lit, the light distribution is more uniform, which is beneficial to improve the light efficiency uniformity of the light emitting surface 212.

[0068] It can be understood that if the first light emitting group 11 includes at least two first light emitting lamps 111, the working mode of the first light emitting group 11 can include that all the first light emitting lamps 111 in the first light emitting group 11 are lit, and part of the first light emitting lamps 111 in the first light emitting group 11 are lit while the remaining first light emitting lamps 111 are not lit. The working mode of the first light emitting group 11 can be flexibly adjusted according to the use demand, which is not limited.

[0069] The first direction x intersects the second direction y. That is, the distribution direction of the first light emitting group 11 and the second light emitting group 12 intersects the distribution direction of the first light emitting lamp 111 in the first light emitting group 11, so that the arrangement of the first light emitting lamp 111 and the second light emitting lamp 121 is more dispersed, which is beneficial to heat dissipation. In some embodiments, the first direction x is perpendicular to the second direction y, so that the arrangement of the first light emitting lamp 111 and the second light emitting lamp 121 is more regular.

[0070] The first light emitting lamp 111 is an LED lamp. The LED lamp has the advantages of energy saving, high efficiency, long service life and small size.

[0071] The first light emitting group 11 includes a single-color LED lamp. The single-color LED lamp can emit light of a single color, has high color consistency, stable light efficiency, uniform brightness and low power consumption. The first light emitting group 11 includes a multi-color LED lamp. The multi-color LED lamp can meet the demand for color diversity. The first light emitting group 11 can include both single-color LED lamps and multi-color LED lamps, that is, part of the first light emitting lamps 111 in the first light emitting group 11 are single-color LED lamps, and part of the first light emitting lamps 111 are multi-color LED lamps, which can realize more rich colors. The multi-color LED lamp can be a double-color LED lamp or a three-color LED lamp.

[0072] The second light emitting group 12 includes at least two second light emitting lamps 121 distributed along the second direction y. It can be understood that for the same light emitting surface 212, the more the number of second light emitting lamps 121, the more beneficial to realize brighter overall lighting effect and reduce dark areas.

[0073] In some embodiments, the second light emitting group 12 includes at least three second light emitting lamps 121 distributed along the second direction y at equal intervals, so that when all the second light emitting lamps 121 are lit, the light distribution is more uniform, which is beneficial to improve the light efficiency uniformity of the light emitting surface 212.

[0074] It can be understood that if the second light emitting group 12 includes at least two second light emitting lamps 121, the working mode of the second light emitting group 12 can include that all the second light emitting lamps 121 in the second light emitting group 12 are lit, and part of the second light emitting lamps 121 in the second light emitting group 12 are lit while the remaining part of the second light emitting lamps 121 are not lit.

[0075] The working mode of the second light emitting group 12 can be flexibly adjusted according to the use demand, which is not limited.

[0076] If the first light-emitting group 11 includes at least two first light-emitting lamps 111 spaced along the second direction y, and the second light-emitting group 12 includes at least two second light-emitting lamps 121 spaced along the second direction y, the first light-emitting lamps 111 and the second light-emitting lamps 121 can be arranged one by one in the first direction x, or can be arranged staggered in the first direction x.

[0077] The working modes of the light-emitting structure 1 can include: all the first light-emitting lamps 111 in the first light-emitting group 11 are lit, all the second light-emitting lamps 121 in the second light-emitting group 12 are lit, part of the first light-emitting lamps 111 in the first light-emitting group 11 are lit, and part of the second light-emitting lamps 121 in the second light-emitting group 12 are lit. It should be noted that if part of the first light-emitting lamps 111 in the first light-emitting group 11 are lit, and part of the second light-emitting lamps 121 in the second light-emitting group 12 are lit, the lit first light-emitting lamps 111 and the lit second light-emitting lamps 121 are staggered in the first direction x, so that they can fill each other when lit, improving the light efficiency uniformity of the light-emitting surface 212.

[0078] The second light-emitting lamp 121 is an LED lamp. The LED lamp has the advantages of energy saving, high efficiency, long service life, and small size.

[0079] The second light-emitting group 12 includes single-color LED lamps. Single-color LED lamps can emit light of a single color, have high color consistency, stable light efficiency, uniform brightness, and low power consumption. The second light-emitting group 12 includes multi-color LED lamps. Multi-color LED lamps can meet the demand for color diversity. The second light-emitting group 12 can include both single-color LED lamps and multi-color LED lamps, that is, part of the second light-emitting lamps 121 in the second light-emitting group 12 are single-color LED lamps, and part of the second light-emitting lamps 121 are multi-color LED lamps, which can achieve more rich colors by superposition. Among them, the multi-color LED lamp can be a double-color LED lamp or a three-color LED lamp.

[0080] The first light-emitting group 11 and the second light-emitting group 12 can be mounted on the same side of the circuit board 13, that is, the circuit board 13 has a first surface 131 and a second surface 132 distributed along the third direction z, and the first light-emitting group 11 and the second light-emitting group 12 are both mounted on the first surface 131. Among them, the first direction x, the second direction y, and the third direction z are perpendicular to each other.

[0081] In some embodiments, the first direction x can be along the length direction of the circuit board 13, the second direction y can be along the width direction of the circuit board 13, and the third direction z can be along the thickness direction of the circuit board 13. That is, the first light-emitting group 11 and the second light-emitting group 12 are mounted on the same side of the thickness direction of the circuit board 13.

[0082] Next, refer to Figures 3 to 9The thick-wall light guide 20 will be described in detail.

[0083] The main body 21 of the thick-wall light guide 20 has a light exit surface 212 for emitting the first light and the second light. In this way, the first light emitting group 11 and the second light emitting group 12 can emit light through the light exit surface 212 and display different light effects at the light exit surface 212.

[0084] The light exit surface 212 is provided with optical patterns, which are beneficial to diffuse light and achieve uniform light effect.

[0085] The main body 21 has an optical surface 211 opposite to the light exit surface 212. The optical surface 211 is used to receive the first light and the second light and transmit the first light and the second light to the light exit surface 212 for emission.

[0086] The optical surface 211 includes a first surface 2111, which is obliquely arranged towards the light collecting part 22 and is used to at least receive the first light emitted by the light collecting part 22 and reflect the first light so that the first light is emitted through the light exit surface 212.

[0087] The oblique arrangement of the first surface 2111 towards the light collecting part 22 can achieve that more first light has an incident angle greater than the critical angle when reaching the first surface 2111, so that total reflection occurs at the first surface 2111 and light loss is reduced.

[0088] The oblique angle of the first surface 2111 towards the light collecting part 22 can be determined according to the refractive index of the main body 21 and other factors, which is not limited.

[0089] The first surface 2111 extends along the second direction y. That is, the extension direction of the first surface 2111 is consistent with the distribution direction of the first light emitting lamps 111 in the first light emitting group 11, which is beneficial to the first surface 2111 to receive all the first light emitted by the first light emitting lamps 111 and reflect the first light.

[0090] The optical surface 211 includes a plurality of first surfaces 2111 spaced apart along the third direction z. The more the number of the first surfaces 2111, the more dense the distribution of the first surfaces 2111, and the smaller the interval between the adjacent two first surfaces 2111. When the light effect on the light exit surface 212 is observed by the naked eye, the dark area effect on the light exit surface 212 cannot be felt.

[0091] The optical surface 211 further includes a second surface 2112 connected between the adjacent two first surfaces 2111, and the second surface 2112 is arranged at an angle with the first surface 2111. The second surface 2112 can not be inclined relative to the light collecting part 22.

[0092] The optical surface 211 is also used to receive the second light rays outputted by the reflective light collector 30 and refract into the thick-walled light guide 20, so that the second light rays are emitted through the light emitting surface 212. The optical surface 211 can be regarded as the interface between the main body 21 and air, and the second light rays outputted by the reflective light collector 30 pass through the air and then enter the main body 21, i.e., from the optically thinner medium to the optically denser medium, and can be refracted into the main body 21 at the optical surface 211.

[0093] It can be understood that, since the second light rays are refracted through the optical surface 211 with the medium characteristics, the first surface 2111 and the second surface 2112 can both receive the second light rays outputted by the reflective light collector 30 and refract into the thick-walled light guide 20, so that the second light rays are emitted through the light emitting surface 212.

[0094] The optical surface 211 and the light emitting surface 212 can be oppositely distributed along the first direction x. The main body 21 can extend along the first direction x.

[0095] The thick-walled light guide 20 includes light collecting portions 22 corresponding to the first light emitting lamps 111 one by one, and each light collecting portion 22 is used to collect the first light rays emitted by the corresponding first light emitting lamp 111. For example, the first light emitting group 11 includes N first light emitting lamps 111 distributed along the second direction y, and the thick-walled light guide 20 includes N light collecting portions 22 distributed along the second direction y, and the N light collecting portions 22 are arranged corresponding to the N first light emitting lamps 111 one by one.

[0096] The light collecting portions 22 and the main body 21 are integrally formed, so as to reduce the assembly process and lower the production cost.

[0097] Next, the reflective light collector 30 will be described in detail with reference to Figure 3 and Figure 4

[0098] The distribution directions of the reflective light collector 30 and the thick-walled light guide 20 are consistent with the distribution directions of the second light emitting group 12 and the first light emitting group 11. In this way, the reflective light collector 30 is facilitated to receive the second light rays emitted by the second light emitting group 12 and collect the second light rays.

[0099] The reflective light collector 30 is located on the side of the optical surface 211 of the thick-walled light guide 20, so as to facilitate the reflective light collector 30 to transmit the second light rays towards the optical surface 211.

[0100] ​The reflective light concentrator 30 comprises a reflective light concentrating element 31 corresponding to each second light emitting lamp 121, each reflective light concentrating element 31 being configured to concentrate the second light emitted by the corresponding second light emitting lamp 121. For example, when the second light emitting group 12 comprises M second light emitting lamps 121 distributed along the second direction y, the reflective light concentrator 30 comprises M reflective light concentrating elements 31 distributed along the second direction y, the M reflective light concentrating elements 31 being arranged one-to-one corresponding to the M second light emitting lamps 121.

[0101] The reflective light concentrating elements 31 in the reflective light concentrator 30 are connected as a whole, so as to reduce the assembly alignment process.

[0102] The reflective light concentrating elements 31 in the reflective light concentrator 30 are integrally formed, so as to reduce the assembly process and save the assembly cost.

[0103] The reflective light concentrating element 31 is a reflective bowl. The reflective bowl can more effectively concentrate light through the design of the reflective surface, and significantly improve the overall brightness.

[0104] In summary, the embodiments of the present application design the first light emitting group 11 and the second light emitting group 12 with different light functions. The first light emitted by the first light emitting group 11 is concentrated by the light concentrating part 22 and transmitted into the main part 21, reflected by the optical surface 211 of the main part 21, and finally diffused out of the light emitting surface 212 pattern; the second light emitted by the second light emitting group 12 is concentrated by the reflective light concentrator 30 and transmitted to the optical surface 211 of the main part 21, refracted into the thick-walled light guide 20 through the optical surface 211 of the main part 21, and finally diffused out of the light emitting surface 212 pattern.
