[0046] Hereinafter, the embodiments will be described with reference to the drawings.

It should be noted that for the sake of convenience of description, only the parts related to the relevant utility model are shown in the drawings. Without conflict, the embodiments and the features in the embodiments of the present utility model can be combined with each other.
[0047] Combined with Figures 1 - 12 ( Figure 4(The optical element 300 is not shown), the light-emitting assembly disclosed in the present utility model includes a rigid circuit board 100, a flexible circuit board 200, and an optical element 300.

[0048] One of the first lamp beads 110 and the second lamp beads 210 is a white light lamp bead for emitting white light, which can realize the function of a daytime lamp or a position lamp, and the other is a yellow light lamp bead for emitting yellow light, which can realize
[0049] the function of a turn signal lamp; a plurality of first condensing parts 310 and a plurality of second condensing parts 320 are provided on the optical element 300, and each of the first condensing parts 310 corresponds to each of the first lamp beads 110 one by one, and each of the second condensing parts 320 corresponds to each of the second lamp beads 210 one by one.
[0050] Taking the first lamp bead 110 as a white light lamp bead and the second lamp bead 210 as a yellow light lamp bead as an example, when it is necessary to use the function of a daytime lamp or a position lamp for illumination, the first lamp bead 110 emits white light, and the light is emitted from the light-emitting surface of the optical element 300 after being converged by the first condensing part 310. When it is necessary to use the function of a turn signal lamp for illumination, the second lamp bead 210 emits yellow light, and the light is emitted from the light-emitting surface of the optical element 300 after being converged by the second condensing part 320.
[0051] Compared with the prior art, the present utility model realizes the separate lighting control of the first lamp bead 110 and the second lamp bead 210 by respectively arranging the first lamp bead 110 and the second lamp bead 210 on the rigid circuit board 100 and the flexible circuit board 200, and the wiring layout is convenient; the staggered arrangement of the first lamp bead 110 and the second lamp bead 210 facilitates the sharing of the optical element 300 by the first lamp bead 110 and the second lamp bead 210, thereby realizing the integration of the functions of a turn signal lamp, a position lamp, and a daytime lamp, and greatly saving the space of the vehicle lamp.
[0052] Specifically, connectors 120 can be respectively provided on the rigid circuit board 100 and the flexible circuit board 200 to be connected to a power source for power-on. Alternatively, in combination with Figure 1 and Figure 2 , in an embodiment, a connector 120 for connecting to a power source is provided on the rigid circuit board 100, and the conductive part of the flexible circuit board 200 is electrically connected to the conductive part of the rigid circuit board 100, so that the connector 120 on the rigid circuit board 100 can supply power to both the rigid circuit board 100 and the flexible circuit board 200 at the same time.
[0053] Specifically, in combination with Figure 3 , openings can be respectively formed on the flexible circuit board 200 and the rigid circuit board 100, and electrical connection can be achieved through conductive components.
[0054] The flexible circuit board 200 can be directly bonded to the rigid circuit board 100 through glue, and the rigid circuit board 100 can be disposed on the radiator to achieve heat dissipation.
[0055] In order to optimize the heat dissipation effect of the light-emitting component, in a specific embodiment disclosed in the present invention, in combination with Figure 8 , Figure 9 and Figure 11 , the light-emitting component further includes a support member 400. There are at least two support members 400, which are supported between the rigid circuit board 100 and the flexible circuit board 200, so that a heat dissipation gap is formed between the rigid circuit board 100 and the flexible circuit board 200.
[0056] Wherein, a liquid cooling plate can be arranged in the heat dissipation gap to perform liquid cooling heat dissipation on the rigid circuit board 100 and the flexible circuit board 200. However, since the size of the heat dissipation gap is usually small, the installation process requirements for the liquid cooling plate are relatively high, resulting in too high cost of this heat dissipation solution. Alternatively, the light-emitting component further includes a cooling fan 500. In combination with Figure 11 , the air outlet of the cooling fan 500 is arranged towards the heat dissipation gap. When the cooling fan 500 blows air, the air flow passes through the heat dissipation gap and takes away the heat of the rigid circuit board 100 and the flexible circuit board 200.
[0057] In a specific embodiment disclosed in the present invention, in combination with Figure 13 , the air outlet of the cooling fan 500 is communicated with a first air duct 520 and a second air duct 530 through a shunt member 510. A first air outlet hole 521 is formed on the side wall of the first air duct 520, and the first air outlet hole 521 is arranged towards the heat dissipation gap. A second air outlet hole 531 is formed on the side wall of the second air duct 530, and the second air outlet hole 531 is arranged towards the side of the rigid circuit board 100 facing away from the flexible circuit board 200.
[0058] Wherein, both the first air duct 520 and the second air duct 530 are made of flexible pipes, and the first air duct 520 can be arranged around a part of the circumference of the heat dissipation gap, so that the air flow blown out from the first air duct 520 can be blown out from the part of the heat dissipation gap not surrounded. The second air duct 530 can be bent according to requirements, and each second air outlet hole 531 blows air towards different parts of the rigid circuit board 100 for heat dissipation.
[0059] For a further optimized solution, in combination with Figure 13, a water-cooled heat exchanger 600 can also be provided between the air outlet of the cooling fan 500 and the flow dividing component 510, so that the air flow blown out by the cooling fan 500 is a low-temperature air flow, further optimizing the heat dissipation effect.
[0060] The optical element 300 includes, but is not limited to, a thick-walled part. Optical patterns can be provided on the light-emitting surface of the thick-walled part. The types of optical patterns include, but are not limited to, strip patterns and granular patterns, which are used to achieve the technical effect of uniform light emission.
[0061] Each of the first lamp beads 110 and the second lamp beads 210 can be arranged on the same plane or different planes. Figure 10 , when arranged on different planes, the shapes of the first light condensing part 310 and the second light condensing part 320 can be the same or different.
[0062] The vehicle lamp disclosed by the present utility model includes the above-mentioned light-emitting component, so it also has the above-mentioned structure and beneficial effects. Other structures refer to the prior art and will not be elaborated here.
[0063] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. The specific technical means in some embodiments can be partially or wholly incorporated into another embodiment on the premise that it is not explicitly excluded by another embodiment. Therefore, the present utility model will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
