In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.
[0035] As described in the background technology section, in the prior art, the rear position lights and the license plate lights are usually arranged independently, which makes the overall space occupied by the rear position lights and the license plate lights large and the space utilization rate low, and does not meet the popular trend of miniaturization of vehicle lights in the future; and, circuits need to be set separately to control the opening and closing of the rear position lights and the license plate lights, which results in high cost for the development of electronic components and complex circuit design.
[0036] In view of this, an embodiment of the present application provides a composite vehicle lamp of a rear position light and a license plate light. The composite vehicle lamp of a rear position light and a license plate light provided by the embodiment of the present application includes a shell, the shell has a first opening and a second opening, the first opening is provided with a rear position light inner lampshade, and the second opening is provided with a license plate light lampshade; a light source, a first reflector and a second reflector are provided in the shell, the first reflector includes a first reflective bowl surface and a second reflective bowl surface connected to each other, the second reflector includes a third reflective bowl surface, the first reflective bowl surface is arranged corresponding to the rear position light inner lampshade, the second reflective bowl surface and the third reflective bowl surface are arranged opposite to each other, and the second reflective bowl surface is arranged corresponding to the license plate light lampshade; with such arrangement, part of the light emitted by the light source is transmitted to the first reflective bowl surface, and after being reflected by the first reflective bowl surface, it is emitted from the rear position light inner lampshade; part of the light emitted by the light source is transmitted to the second reflective bowl surface, and after being reflected by the second reflective bowl surface to the third reflective bowl surface, it is emitted from the license plate light lampshade.
[0037] It can be seen that the composite headlight provided in the embodiment of the present application integrates the rear position light and the license plate light, utilizes a common light source and lamp body, and a separate light-transmitting port, to simultaneously realize the functions of the rear position light and the license plate light, thereby saving occupied space, improving the utilization efficiency of the light source, simplifying circuit design, and reducing electronic development costs. In addition, the first reflective bowl surface and the second reflective bowl surface are connected, which can further save occupied space, which is conducive to meeting the popular trend of miniaturization of future headlights.
[0038] Figure 1 FIG. 1 shows a schematic diagram of the structure of a composite lamp of a rear position lamp and a license plate lamp provided in an embodiment of the present application. Figure 1 As shown, the composite lamp of the rear position lamp and the license plate lamp provided in the embodiment of the present application includes a shell 100 having a first opening K1 and a second opening K2. The first opening K1 is provided with a rear position lamp inner lampshade 110, and the second opening K2 is provided with a license plate lampshade 120.
[0039] Optional, such as Figure 1 As shown, in addition to the rear position lamp inner lampshade 110, the first opening K1 may also be provided with a decorative piece 130, and the decorative piece 130 may surround the rear position lamp inner lampshade 110, so that the rear position lamp inner lampshade 110 and the decorative piece 130 jointly cover the first opening K1. It can be understood that the decorative piece 130 may improve the appearance of the rear position lamp and enhance the aesthetics of the rear position lamp.
[0040] Alternatively, the first opening K1 may also be provided with only the rear position lamp inner lamp cover 110 .
[0041] like Figure 1As shown, a light source 200, a first reflector 300 and a second reflector 400 are disposed in the shell 100, wherein the first reflector 300 includes a first reflective bowl surface 310 and a second reflective bowl surface 320 connected to each other, the second reflector 400 includes a third reflective bowl surface 410, the first reflective bowl surface 310 is disposed correspondingly to the inner lampshade 110 of the rear position lamp, the second reflective bowl surface 320 is disposed opposite to the third reflective bowl surface 410, and the second reflective bowl surface 320 is disposed correspondingly to the lampshade 120 of the license plate light.
[0042] It should be noted that, in the embodiment of the present application, the first reflective bowl surface 310 is arranged correspondingly to the rear position lamp inner lampshade 110, which means that the light reflected by the first reflective bowl surface 310 can be emitted from the rear position lamp inner lampshade 110. Similarly, the second reflective bowl surface 320 is arranged oppositely to the third reflective bowl surface 410, which means that the light reflected by the second reflective bowl surface 320 can reach the third reflective bowl surface 410. The second reflective bowl surface 320 is arranged correspondingly to the license plate lamp shade 120, which means that the light reflected by the second reflective bowl surface 320 can be emitted from the license plate lamp shade 120.
[0043] So set up, such as Figure 1 As shown, part of the light emitted by the light source 200 is transmitted to the first reflection bowl surface 310, and after being reflected by the first reflection bowl surface 310, it is emitted from the lampshade 110 inside the rear position lamp to form the rear position lamp output light; part of the light emitted by the light source 200 is transmitted to the second reflection bowl surface 320, and after being reflected by the second reflection bowl surface 320, it is emitted to the third reflection bowl surface 410, and after being reflected by the third reflection bowl surface 410, it is emitted from the lampshade 120 of the license plate lamp to form the license plate lamp output light.
[0044] It is understandable that the first reflective bowl surface 310 is a concave surface, so that part of the light emitted by the light source 200 is transmitted to the first reflective bowl surface 310, and after being reflected by the first reflective bowl surface 310, it converges toward the lampshade 110 in the rear position lamp and is emitted.
[0045] Similarly, the second reflective bowl surface 320 is a concave surface, and the third reflective bowl surface 410 is a concave surface, so that part of the light emitted by the light source 200 is transmitted to the second reflective bowl surface 320, and after being reflected by the second reflective bowl surface 320, it converges to the third reflective bowl surface 410, and then after being reflected by the third reflective bowl surface 410, it converges to the license plate light cover 120 and is emitted.
[0046] It can be seen that the composite vehicle lamp provided in the embodiment of the present application integrates the rear position lamp and the license plate lamp, and uses a common light source and lamp body, as well as separate light transmission ports, to simultaneously realize the functions of the rear position lamp and the license plate lamp, thereby saving space, improving the efficiency of the light source, simplifying circuit design, and reducing electronic development costs. In addition, the first reflective bowl surface 310 and the second reflective bowl surface 320 are connected, which can further save space.
[0047] Optional, such as Figure 1 As shown, the light source 200 includes a light emitting diode (LED) 210 and a printed circuit board (PCB) 220 . It can be understood that the light emitting diode 210 is soldered on the printed circuit board 220 .
[0048] Further optional, such as Figure 1 As shown, the housing 100 includes a bottom 101 and a side wall 102 surrounding the bottom 101 , the first opening K1 is the top opening of the housing 100 , and the second opening K2 is the side wall opening of the housing 100 .
[0049] It is understandable that the first opening K1 may be the entire top opening of the housing 100. Figure 1 As shown, at this time, the first opening K1 may be provided with a decorative piece 130 and a rear position lamp inner lamp cover 110 ; or, the first opening K1 may also be a partial top opening of the housing 100 .
[0050] In this embodiment, Figure 1 As shown, the light-emitting diode 210 and the printed circuit board 220 are located as a whole on one side of the side wall 102 of the shell 100, and the light-emitting diode 210 is located on the side of the first reflective bowl surface 310 away from the bottom 101 of the shell 100. The first reflective bowl surface 310 and the second reflective bowl surface 320 partially surround the light-emitting diode 210 as a whole, and the first reflective bowl surface 310 and the second reflective bowl surface 320 extend in a direction away from the light-emitting diode 210 and in a direction away from the bottom 101 of the shell 100 respectively. That is to say, the first reflective bowl surface 310 and the second reflective bowl surface 320 extend as a whole in an oblique upward direction, so that part of the light emitted by the light-emitting diode 210 can be transmitted to the first reflective bowl surface 310, and then reflected by the first reflective bowl surface 310, and then emitted from the lampshade 110 in the rear position lamp; and part of the light emitted by the light-emitting diode 210 can be transmitted to the second reflective bowl surface 320.
[0051] In this embodiment, Figure 2 As shown, the third reflective bowl surface 410 is located on the side of the second reflective bowl surface 320 away from the bottom 101 of the shell 100, and the second opening K2 is located on the other side of the side wall 102 of the shell 100 opposite to the light-emitting diode 210, so that part of the light emitted by the light-emitting diode 210 can be transmitted to the third reflective bowl surface 410 after being reflected by the second reflective bowl surface 320, and then emitted from the license plate light cover 120 after being reflected by the third reflective bowl surface 410.
[0052] In this embodiment, the light emitting diode 210 may be a single light emitting diode or a plurality of light emitting diodes, depending on the specific situation.
[0053] In practical applications, the printed circuit board 220 can be installed on the first reflector 300, the first reflector 300 can be installed on the housing 100, and the second reflector 400 can be installed on the first reflector 300, so that the relative position of the light-emitting diode 210 and the first reflector 300 is fixed, and the relative position of the first reflector 300 and the second reflector 400 is fixed.
[0054] Figure 2 FIG. 2 shows a schematic diagram of the structure of another composite lamp of a rear position lamp and a license plate lamp provided in an embodiment of the present application. Figure 2 As shown, the composite lamp of the rear position lamp and the license plate lamp provided in the embodiment of the present application includes a shell 100 having a first opening K1 and a second opening K2. The first opening K1 is provided with a rear position lamp inner lampshade 110, and the second opening K2 is provided with a license plate lampshade 120.
[0055] Optional, such as Figure 2 As shown, in addition to the rear position lamp inner lampshade 110, the first opening K1 may also be provided with a decorative piece 130, and the decorative piece 130 may surround the rear position lamp inner lampshade 110, so that the rear position lamp inner lampshade 110 and the decorative piece 130 jointly cover the first opening K1. It can be understood that the decorative piece 130 may improve the appearance of the rear position lamp and enhance the aesthetics of the rear position lamp.
[0056] Alternatively, the first opening K1 may also be provided with only the rear position lamp inner lamp cover 110 .
[0057] like Figure 2 As shown, a light source 200, a first reflector 300 and a second reflector 400 are disposed in the shell 100, wherein the first reflector 300 includes a first reflective bowl surface 310 and a second reflective bowl surface 320 connected to each other, the second reflector 400 includes a third reflective bowl surface 410, the first reflective bowl surface 310 is disposed correspondingly to the inner lampshade 110 of the rear position lamp, the second reflective bowl surface 320 is disposed opposite to the third reflective bowl surface 410, and the second reflective bowl surface 320 is disposed correspondingly to the lampshade 120 of the license plate light.
[0058] It should be noted that, in the embodiment of the present application, the first reflective bowl surface 310 is arranged correspondingly to the rear position lamp inner lampshade 110, which means that the light reflected by the first reflective bowl surface 310 can be emitted from the rear position lamp inner lampshade 110. Similarly, the second reflective bowl surface 320 is arranged oppositely to the third reflective bowl surface 410, which means that the light reflected by the second reflective bowl surface 320 can reach the third reflective bowl surface 410. The second reflective bowl surface 320 is arranged correspondingly to the license plate lamp shade 120, which means that the light reflected by the second reflective bowl surface 320 can be emitted from the license plate lamp shade 120.
[0059] So set up, such as Figure 2 As shown, part of the light emitted by the light source 200 is transmitted to the first reflection bowl surface 310, and after being reflected by the first reflection bowl surface 310, it is emitted from the lampshade 110 inside the rear position lamp to form the rear position lamp output light; part of the light emitted by the light source 200 is transmitted to the second reflection bowl surface 320, and after being reflected by the second reflection bowl surface 320, it is emitted to the third reflection bowl surface 410, and after being reflected by the third reflection bowl surface 410, it is emitted from the lampshade 120 of the license plate lamp to form the license plate lamp output light.
[0060] It is understandable that the first reflective bowl surface 310 is a concave surface, so that part of the light emitted by the light source 200 is transmitted to the first reflective bowl surface 310, and after being reflected by the first reflective bowl surface 310, it converges toward the lampshade 110 in the rear position lamp and is emitted.
[0061] Similarly, the second reflective bowl surface 320 is a concave surface, and the third reflective bowl surface 410 is a concave surface, so that part of the light emitted by the light source 200 is transmitted to the second reflective bowl surface 320, and after being reflected by the second reflective bowl surface 320, it converges to the third reflective bowl surface 410, and then after being reflected by the third reflective bowl surface 410, it converges to the license plate light cover 120 and is emitted.
[0062] It can be seen that the composite headlight provided in the embodiment of the present application integrates the rear position light and the license plate light, utilizes a common light source and lamp body, and a separate light-transmitting port, to simultaneously realize the functions of the rear position light and the license plate light, thereby saving occupied space, improving the utilization efficiency of the light source, simplifying circuit design, and reducing electronic development costs. In addition, the first reflective bowl surface 310 and the second reflective bowl surface 320 are connected, which can further save occupied space, which is conducive to the popular trend of miniaturization of headlights in the future.
[0063] Optional, such as Figure 2 As shown, the light source 200 is a halogen lamp.
[0064] Further optional, such as Figure 2 As shown, the housing 100 includes a bottom 101 and a side wall 102 surrounding the bottom 101 , the first opening K1 is the top opening of the housing 100 , and the second opening K2 is the side wall opening of the housing 100 .
[0065] It is understandable that the first opening K1 may be the entire top opening of the housing 100. Figure 2 As shown, at this time, the first opening K1 may be provided with a decorative piece 130 and a rear position lamp inner lamp cover 110 ; or, the first opening K1 may also be a partial top opening of the housing 100 .
[0066] In this embodiment, Figure 2As shown, the halogen lamp (i.e., the light source 200) is located on the side of the first reflective bowl surface 310 away from the bottom 101 of the shell 100, and the first reflective bowl surface 310 and the second reflective bowl surface 320 partially surround the halogen lamp (i.e., the light source 200) as a whole. That is to say, the first reflective bowl surface 310 and the second reflective bowl surface 320 surround the halogen lamp (i.e., the light source 200) as a whole from below, so that part of the light emitted by the halogen lamp (i.e., the light source 200) can be transmitted to the first reflective bowl surface 310 to a greater extent, and then reflected by the first reflective bowl surface 310, and then emitted from the lampshade 110 in the rear position lamp; and part of the light emitted by the halogen lamp (i.e., the light source 200) can be transmitted to the second reflective bowl surface 320 to a greater extent.
[0067] In this embodiment, Figure 2 As shown, the third reflective bowl surface 410 is located on the side of the second reflective bowl surface 320 away from the bottom 101 of the shell 100, so that part of the light emitted by the light-emitting diode 210 can be transmitted to the third reflective bowl surface 410 after being reflected by the second reflective bowl surface 320, and then emitted from the license plate light cover 120 after being reflected by the third reflective bowl surface 410.
[0068] In this embodiment, Figure 2 As shown, part of the light emitted by the halogen lamp (ie, the light source 200 ) can also be directly emitted from the lampshade 110 inside the rear position lamp to further improve the use efficiency of the light source.
[0069] In practical applications, the halogen lamp (i.e., the light source 200) can be mounted on the first reflector 300, the first reflector 300 can be mounted on the housing 100, and the second reflector 400 can be mounted on the first reflector 300, so that the relative positions of the halogen lamp (i.e., the light source 200) and the first reflector 300 are fixed, and the relative positions of the first reflector 300 and the second reflector 400 are fixed.
[0070] As we know, halogen lamps are used as light sources 200. The wavelength of light emitted by halogen bulbs is long and penetrating, which can provide better sight in bad weather conditions such as rain, snow, fog, etc. Moreover, halogen bulbs have a high color rendering index and can provide good color reproduction, making the color of objects closer to the state under natural light when driving at night. Halogen bulbs are fast to light up with almost no delay, which is very important for night driving environments that require quick response. The cost of halogen bulbs is relatively low, which makes them widely used in economical vehicles. Halogen bulb technology is mature, maintenance and replacement are relatively simple, and accessories are easy to obtain. However, halogen lamps are relatively dim, have only one color temperature, and emit yellowish light. As light sources 200, light-emitting diodes have a very fast response speed and can reach maximum brightness in a short time; the energy consumption is relatively small, usually about 20W; the life is longer, usually up to 50,000 hours or even more, which means that they hardly need to be replaced during the entire service life of the vehicle, thereby reducing maintenance costs. In practical applications, the light source 200 can be selected as a halogen lamp or a light-emitting diode according to actual needs.
[0071] Based on any of the above embodiments, optionally, Figure 2 As shown, the area of the first reflective bowl surface 310 may be greater than the area of the second reflective bowl surface 320 .
[0072] We know that no matter the light source 200 is a light-emitting diode 210 or a halogen lamp, the light emitted by the light source 200 is directed in all directions. Therefore, part of the light emitted by the light source 200 reaches the first reflection bowl surface 310 and is reflected by the first reflection bowl surface 310, and cannot achieve total reflection. Part of the light emitted by the light source 200 reaches the second reflection bowl surface 320 and is reflected by the second reflection bowl surface 320 toward the third reflection bowl surface 410. The second reflection bowl surface 320 and the third reflection bowl surface 410 can be made to achieve total reflection by debugging. Therefore, in this embodiment, the area of the first reflection bowl surface 310 can be set to be larger than the area of the second reflection bowl surface 320, so that more light emitted by the light source 200 is reflected by the first reflection bowl surface 310, and then emitted from the lampshade 110 inside the rear position lamp, thereby improving the brightness of the rear position lamp.
[0073] From the above analysis, it can be known that, optionally, the second reflection bowl surface 320 can be a total reflection surface, and the third total reflection bowl surface 410 can be a total reflection surface, so that the brightness of the license plate light can also be improved.
[0074] It should be noted that, in the embodiment of the present application, the second reflective bowl surface 320 is a total reflection surface, which means that the light emitted by the light source 200 and irradiated to the second reflective bowl surface 320 is almost completely reflected to the third total reflection bowl surface 410. Similarly, the third reflective bowl surface 410 is a total reflection surface, which means that the light emitted by the light source 200 and irradiated to the second reflective bowl surface 320 is totally reflected by the second reflective bowl surface 320, and then almost completely reflected by the third total reflection bowl surface 410 into the license plate lamp cover 120, and then emitted from the license plate lamp cover 120.
[0075] Based on any of the above embodiments, optionally, Figure 1 and Figure 2 As shown, the composite lamp of the rear position lamp and the license plate lamp provided in the embodiment of the present application may further include a rear position lamp outer lampshade 140 , which covers the rear position lamp inner lampshade 110 and the decorative member 130 provided in the first opening K1 .
[0076] In summary, the composite lamp of the rear position lamp and the license plate lamp provided in the embodiment of the present application comprises a housing 100, the housing 100 having a first opening K1 and a second opening K2, the first opening K1 being provided with a rear position lamp inner lampshade 110, the second opening K2 being provided with a license plate lampshade 120; a light source 200, a first reflector 300 and a second reflector 400 are provided in the housing 100, the first reflector 300 comprising a first reflective bowl surface 310 and a second reflective bowl surface 320 connected to each other, the second reflector 400 comprising a third reflective bowl surface 410, the first reflective bowl surface 310 and the rear position lamp inner lampshade 110 are provided to the first opening K1 and the license plate lamp inner lampshade 120; The position lamp inner lampshade 110 is arranged correspondingly, the second reflection bowl surface 320 and the third reflection bowl surface 410 are arranged oppositely, and the second reflection bowl surface 320 and the license plate lampshade 120 are arranged correspondingly; in this arrangement, part of the light emitted by the light source 200 is transmitted to the first reflection bowl surface 310, and after being reflected by the first reflection bowl surface 310, it is emitted from the rear position lamp inner lampshade 110; part of the light emitted by the light source 200 is transmitted to the second reflection bowl surface 320, and after being reflected by the second reflection bowl surface 320 to the third reflection bowl surface 410, it is emitted from the license plate lampshade 120. It can be seen that the composite vehicle lamp provided in the embodiment of the present application integrates the rear position lamp and the license plate lamp together, and uses a common light source and lamp body, as well as a separate light transmission port, to realize the functions of the rear position lamp and the license plate lamp at the same time, thereby saving the occupied space, improving the efficiency of the light source, simplifying the circuit design, and reducing the electronic development cost. In addition, the first reflection bowl surface and the second reflection bowl surface are connected, which can further save the occupied space, which is conducive to the popular trend of miniaturization of vehicle lamps in the future.
