Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0040] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" 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 a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] Please refer to Figure 1-Figure 15 The present embodiment provides a lamp assembly 100, including a light source assembly 110, an integrally formed protection plate 120 and a reflective structure 130, wherein the protection plate 120 is made of a light-transmitting material, and the reflective structure 130 is made of an opaque material. The light emitted by the light source assembly 110 enters the protection plate 120, is reflected by the contact surface between the protection plate 120 and the reflective structure 130, and then is emitted from a light-emitting surface 126 of the protection plate 120.

[0042] Specifically, compared to the structure that only uses a reflective plate for reflective lighting, the present application integrally forms the protective plate 120 and the reflective structure 130, which can protect the reflective surface of the protective plate 120 including the reflective structure 130 from wear and tear, while eliminating the conventional cavity structure, thereby avoiding the generation of fog, and further improving the stability of the luminous performance of the lamp assembly 100. In addition, the protective plate 120 has a protective function, so that the lamp assembly 100 does not need to be provided with a shell, which makes the lamp assembly 100 miniaturized while reducing the hardware cost. After the light emitted by the light source assembly 110 enters the protective plate 120, it is reflected by the contact surface between the protective plate 120 and the reflective structure 130 and then emitted from the light emitting surface 126 of the protective plate 120, so that the lamp assembly 100 can emit light.

[0043] Furthermore, the heat sink 150 may be connected to the reflective structure 130 , and the light source assembly 110 may be disposed on the heat sink 150 , so that the heat generated by the light source assembly 110 can be dissipated and volatilized through the heat sink 150 .

[0044] In some feasible embodiments of the present application, Figure 5-Figure 10As shown, the protection plate 120 includes a light guiding section 121 and a light emitting section 122 that are interconnected, the light guiding section 121 is provided with a first light incident surface 1211, and the light emitting surface 126 is arranged on the light emitting section 122, the lamp assembly 100 also includes a first reflecting surface 1212 located on both sides of the first light incident surface 1211 and a second reflecting surface 1221 located on the light emitting section 122, the second reflecting surface 1221 is a partial contact surface between the light emitting section 122 of the protection plate 120 and the reflective structure 130, the light source assembly 110 includes a first light source assembly 111, the first light source assembly 111 is arranged relative to the first light incident surface 1211, after the light emitted by the first light source assembly 111 enters the light guiding section 121 of the protection plate 120 through the first light incident surface 1211, at least part of the light is reflected by the first reflecting surface 1212 to the second reflecting surface 1221 of the light emitting section 122, and is reflected by the second reflecting surface 1221 to be emitted from the light emitting surface 126. Thus, the light emitted by the first light source assembly 111 is guided to the light emitting surface 126 of the protection plate 120 through the light guiding section 121 and the light emitting section 122 of the protection plate 120 and the reflection by the first reflecting surface 1212 and the second reflecting surface 1221 .

[0045] For example, Fig.10 As shown, the light guide segment 121 and the light emitting segment 122 extend in the same direction, the first light incident surface 1211 and the light emitting surface 126 can be perpendicular to each other, or they can be at an angle of nearly 90 degrees (this application is not limited to this), and the first reflective surface 1212 is at least a partial contact surface between the light guide segment 121 of the protective plate 120 and the reflective structure 130. Therefore, in this embodiment, the light emitted by the first light source assembly 111 enters the light guide segment 121 through the first light incident surface 1211 in a divergent shape, is reflected and transmitted to the light emitting segment 122 by the first reflective surface 1212 on the light guide segment 121, and is reflected to the light emitting surface 126 by the second reflective surface 1221, so as to realize the light emitting requirement of the lamp assembly 100.

[0046] For example, Figure 5-Figure 9As shown, the light guide segment 121 and the light emitting segment 122 can be perpendicular to each other, or they can be at an angle of nearly 90 degrees (this application is not limited to this), the first light incident surface 1211 is arranged on the side of the first reflective surface 1212 away from the light emitting surface 126, and the first reflective surface 1212 and the light emitting surface 126 can be parallel to each other (this application is not limited to this). The first light source assembly 111 emits light along the light emitting direction of the light emitting surface 126, the first reflective surface 1212 is at least part of the contact surface between the light guide segment 121 of the protective plate 120 and the reflective structure 130, the light emitted by the first light source assembly 111 enters the light guide segment 121 through the first light incident surface 1211, at least part of it is reflected and transmitted to the second reflective surface 1221 through the first reflective surface 1212 on the light guide segment 121, and is reflected to the light emitting surface 126 through the second reflective surface 1221, thereby, the light emitting requirements of the lamp assembly 100 are achieved by setting the light source at a different position from the above-mentioned embodiment and the protective plate 120 with a different structure. In some embodiments, the first light incident surface 1211 allows the light emitted by the first light source assembly 111 to enter the light guide segment 121 in a divergent shape, and the first light source assembly 111 is reflected and transmitted to the second reflective surface 1221 through the first reflective surface 1212 on the light guide segment 121, and is reflected to the light emitting surface 126 through the second reflective surface 1221. In other embodiments, the first light incident surface 1211 has a groove, and the first light source assembly 111 is located in the groove, and the first light incident surface 1211 allows the light emitted by the first light source assembly 111 to enter the light guide segment 121 in the form of parallel light or approximately parallel light. In this embodiment, the stray light emitted by the first light source assembly 111 is reflected and transmitted to the second reflective surface 1221 through the first reflective surface 1212 on the light guide segment 121.

[0047] Furthermore, the lamp assembly 100 may also include a third reflective surface 123, the third reflective surface 123 is at a preset angle with the first reflective surface 1212 and the second reflective surface 1221, and the third reflective surface 123 reflects at least part of the light emitted by the first light source assembly 111 to the second reflective surface 1221, that is, the third reflective surface 123 is formed by extending from the first reflective surface 1212 away from the second reflective surface 1221; or the third reflective surface 123 is located at the connecting part of the light guide segment 121 and the light output segment 122.

[0048] In an embodiment in which the first light incident surface 1211 causes the light emitted by the first light source component 111 to enter the light guide segment 121 in a divergent shape, the first light source component 111 is reflected by the first reflection surface 1212 on the light guide segment 121 to the third reflection surface 123, reflected by the third reflection surface 123 to the second reflection surface 1221, and reflected by the second reflection surface 1221 to the light emitting surface 126.

[0049] In the embodiment where the first light incident surface 1211 allows the light emitted by the first light source assembly 111 to enter the light guide segment 121 in the form of parallel light or approximately parallel light, most of the light emitted by the first light source assembly 111 enters the light guide segment 121 and is directly transmitted to the third reflection surface 123, reflected by the third reflection surface 123 and transmitted to the second reflection surface 1221, and reflected to the light emitting surface 126 through the second reflection surface 1221. The stray light emitted by the first light source assembly 111 is reflected to the third reflection surface 123 through the first reflection surface 1212 on the light guide segment 121, reflected by the third reflection surface 123 and transmitted to the second reflection surface 1221, and reflected to the light emitting surface 126 through the second reflection surface 1221. In this way, the light emitting requirement of the lamp assembly 100 is achieved.

[0050] Furthermore, if Figure 7 As shown, the light passing through the second reflective surface 1221 can also pass through the other contact surface of the protection plate 120 and the reflective structure 130 (such as Figure 7 After being reflected again by the contact surface on the right side of the middle, the light is emitted from the light emitting surface 126.

[0051] Another example, such as Figure 8 As shown, when the light emitting segment 122 extends in multiple directions from the light guiding segment 121, an inverted V-shaped reflecting surface can be set at the connection between the light emitting segment 122 and the light guiding segment 121 as the third reflecting surface 123. According to the setting position and structure of the light emitting segment 122, the third reflecting surface 123 can be formed by a conical groove, a triangular prism groove, or other grooves with an inverted V-shaped cross section at the connection between the light emitting segment 122 and the light guiding segment 121, corresponding to the light emitting segment 122. In this embodiment, since the third reflecting surface 123 is formed by a groove, the third reflecting surface 123 can achieve total reflection. The light emitting surface 126 is connected to the third reflecting surface 123, and the second reflecting surface 1221 is arranged opposite to the light emitting surface 126. After the light emitted by the light source assembly 110 enters the light guide segment 121 from the first light incident surface 1211, it is reflected and transmitted to the inverted V-shaped reflecting surface by the first reflecting surface 1212 on the light guide segment 121. The light projected onto the V-shaped reflecting surface is reflected to the second reflecting surface 1221 by the inverted V-shaped reflecting surface, and then the light projected onto the second reflecting surface 1221 is reflected to the light emitting surface 126 by the second reflecting surface 1221 and then emitted.

[0052] Another example, such as Fig. 9As shown, when the light emitting segment 122 extends in multiple directions from the light guiding segment 121, an inverted V-shaped reflecting surface can be set at the connection between the light emitting segment 122 and the light guiding segment 121 as the third reflecting surface 123. According to the setting position and structure of the light emitting segment 122, the third reflecting surface 123 can be formed by a conical reflecting element, a triangular prism reflecting element or other reflecting elements with an inverted V-shaped cross section at the connection between the light emitting segment 122 and the light guiding segment 121, corresponding to the light emitting segment 122. The light emitting surface 126 is connected to the third reflecting surface 123, and the second reflecting surface 1221 is arranged opposite to the light emitting surface 126. After the light emitted by the light source assembly 110 enters the light guide segment 121 from the first light incident surface 1211, it is reflected and transmitted to the inverted V-shaped reflecting surface by the first reflecting surface 1212 on the light guide segment 121. The light projected onto the V-shaped reflecting surface is reflected to the second reflecting surface 1221 by the inverted V-shaped reflecting surface, and then the light projected onto the second reflecting surface 1221 is reflected to the light emitting surface 126 by the second reflecting surface 1221 and then emitted.

[0053] In a feasible embodiment of the present application, Fig.11 and Fig.12 As shown, the light emitting surface 126 of the protective plate 120 forms a second light incident surface 124, the lamp assembly 100 includes a fourth reflective surface 125, and the fourth reflective surface 125 is at least a partial contact surface between the protective plate 120 and the reflective structure 130. The light source assembly 110 includes a second light source assembly 112, and the second light source assembly 112 is arranged relative to the second light incident surface 124. The light emitted by the second light source assembly 112 enters the protective plate 120 through the second light incident surface 124, is reflected by the fourth reflective surface 125, and is emitted from the light emitting surface 126.

[0054] Specifically, the light source assembly 110 can be arranged at the bottom of the second light incident surface 124 and the light source assembly 110 has a preset distance from the second light incident surface 124. The light source assembly 110 emits light toward the second light incident surface 124 at a preset angle. After the light enters the protective plate 120, it is projected onto the fourth reflective surface 125. The fourth reflective surface 125 reflects the light projected thereon to the light emitting surface 126 and then emits it from the light emitting surface 126 to realize the lighting of the lamp assembly 100.

[0055] In a feasible embodiment of the present application, Figure 1 , Figure 2 and Figure 3 As shown, the second light source assembly 112 may include a light source 1121 and a concentrator 1122. The divergent light emitted by the light source 1121 is shaped into parallel light by the concentrator 1122 and then incident from the second light incident surface 124. Thus, the divergent light emitted by the light source 1121 can be irradiated within the range of the second light incident surface 124 through the concentrator 1122.

[0056] Specifically, the light source assembly 110 is disposed at the bottom of the second light incident surface 124 and the light source assembly 110 and the second light incident surface 124 have a preset distance. The divergent light emitted by the light source 1121 is shaped into parallel light by the condenser 1122 and then emitted toward the second light incident surface 124. The light enters the protection plate 120 and is projected onto the fourth reflective surface 125. The fourth reflective surface 125 reflects the light projected thereon to the light emitting surface 126 and then emits from the light emitting surface 126 to realize the illumination of the lamp assembly 100. The incident direction of the parallel light is set at an acute angle to the light emitting surface 126, so as to avoid the light source assembly 110 from interfering with the light beam emitted from the light emitting surface 126.

[0057] The light emitted by the light source assembly 110 is directly projected onto the fourth reflective surface 125 through the protection plate 120 to ensure the light brightness of the lamp assembly 100 .

[0058] For further information, please refer to Fig.13 A light guide segment 121 may be provided on the side and back of the light emitting segment 122, a first light source assembly 111 may be provided on the first light incident surface 1211 of the plurality of light guide segments 121, and a second light source assembly 112 may be provided on the opposite side of the second light incident surface 124, and the luminous effect of the lamp assembly 100 may be enhanced by lighting the first light source assembly 111 and the second light source assembly 112.

[0059] In a feasible embodiment of the present application, Figure 5-Figure 10 As shown, a micro-pattern structure 127 is provided entirely or partially on the contact surface between the protection plate 120 and the reflective structure 130 to optimize the light emission uniformity of the lamp assembly 100 .

[0060] In a feasible embodiment of the present application, Figure 6 As shown, the side of the protection plate 120 opposite to the light emitting surface 126 is coated with a reflective film 140 .

[0061] Specifically, the reflective film 140 is coated on the side of the protection plate 120 relative to the light emitting surface 126, which can enhance the reflective effect of the contact surface between the protection plate 120 and the reflective structure 130. Furthermore, in order to protect the reflective film 140, a protective shell can also be provided, because the fog generated in the lamp cavity between the protective shell and the reflective film 140 is invisible, so as not to affect the optical performance of the lamp assembly 100.

[0062] In a feasible embodiment of the present application, the light emitting surface 126 of the protection plate 120 may be coated to improve the hardness of the light emitting surface and prevent scratches. In a feasible embodiment of the present application, the light emitting surface 126 of the protection plate 120 may be coated with an anti-reflection film to improve light extraction efficiency.

[0063] In a feasible embodiment of the present application, Figure 1 , Figure 2and Figure 3 As shown, the reflective structure 130 is white or other colors, the protection plate 120 is made of white transparent material or other color transparent material, and the light emitted by the light source assembly 110 is white light or other color light.

[0064] The reflective structure 130 is colored or achromatic, the protective plate 120 is colored transparent material or achromatic transparent material, and the light emitted by the light source assembly 110 is colored light or achromatic light. Achromatic light is black, white, and gray. Colored light is other colors.

[0065] For example, when the light emitted by the light source assembly 110 is white light, and the reflective structure 130 and the protection plate 120 are also set to white, the light emitted from the exit surface is white light.

[0066] When the light emitted by the light source assembly 110 is white light, and the reflective structure 130 and the protection plate 120 have colors and the colors are the same, the color of the light emitted from the exit surface is the same as the color of the reflective structure 130 .

[0067] When the light emitted by the light source assembly 110 is white light, and the reflective structure 130 and the protection plate 120 have colors and the colors are different, the color of the light emitted from the exit surface is mixed color light.

[0068] When the light emitted by the light source assembly 110 is monochromatic light, and the reflective structure 130 and the protection plate 120 are also set to white, the color of the light emitted from the exit surface is monochromatic light.

[0069] When the light emitted by the light source assembly 110 is monochromatic light, and the reflective structure 130 and the protection plate 120 have colors and the colors are different, the color of the light emitted from the exit surface is mixed color light.

[0070] For example, the lamp assembly 100 includes a reflective screen assembly consisting of multiple groups of light source assemblies 110, reflective structures 130 and protective plates 120. The multiple groups of reflective screen assemblies are arranged in a straight line, and the reflective structures 130 and protective plates 120 of the multiple groups of reflective screen assemblies can be set to different colors to achieve different lighting effects of the lamp assembly 100.

The headlight includes the same structure and beneficial effects as the lamp assembly 100 in the aforementioned embodiment. The structure and beneficial effects of the lamp assembly 100 have been described in detail in the aforementioned embodiment, and will not be repeated here. In some embodiments, considering that when the headlight is installed on the vehicle body, there may be space between the headlight and the vehicle body, and there is a risk of dust entering. For this reason, the light-emitting surface of the headlight and the vehicle body can be located in a continuous surface, and the gap between the headlight and the vehicle body can be reduced to reduce the risk of dust entering. In various embodiments of the present application, the lamp assembly 100 can be used as a high beam, a low beam, a signal light or a headlight with other functions. The headlight provided in the present application may include one or more lamp assemblies 100, so that the lamp assembly 100 can realize different headlight functions; or the headlight may include one or more functional lamps, as well as the lamp assembly 100. The present application can realize more different implementation methods, which will not be repeated here.
