DETAILED DESCRIPTION

[0043] The utility model discloses a multifunctional light-emitting module, which improves the heat dissipation effect and ensures the service life. In addition, the utility model also discloses a vehicle lamp with the multifunctional light-emitting module and a vehicle with the vehicle lamp.

[0044] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0046] As competition in the automotive industry intensifies, the requirements for vehicle exterior parts are getting higher and higher, especially the cost requirements for headlights.

[0047] At present, the multiplexing of three functions of the vehicle's front combination lamps (including position, daytime and turning) has become the preferred solution for headlights.

[0048] However, since the headlight panel integrates three functional lights, the density of the lamp beads on the panel is very high. After the lamp beads are started, the heat generated is easily accumulated on the panel, affecting the service life of the headlight.

[0049] Based on this, the multifunctional light-emitting module in the present application sets lamp beads with different functions on different lamp boards, reducing the density of the lamp beads on the lamp boards, thereby reducing the accumulation of heat on the lamp boards and ensuring the service life of the multifunctional light-emitting module.

[0050] Combination Figures 1 to 5 As shown, the multifunctional light-emitting module in the present application includes: a housing 2 , a thick-walled member 1 , a first light board assembly 3 , a second light board assembly 4 and a light guide 5 .

[0051] The housing 2 is the installation base of the entire multifunctional light-emitting module, and the housing 2 has an installation space inside for installing other components. The shape and size of the housing 2 are not specifically limited.

[0052] The thick-walled member 1 can be a lens and serve as the light-emitting surface of the first light panel assembly 3 and the second light panel assembly 4, that is, the first light panel assembly 3 and the second light panel assembly 4 share a common light-emitting area. The size and shape of the thick-walled member 1 are not specifically limited and can be set according to different needs.

[0053] The first light panel assembly 3 and the second light panel assembly 4 are both installed in the installation space of the housing 2. In some embodiments, the first light panel assembly 3 can be used as a daytime running light and a position indicator light. According to other application scenarios, the first light panel assembly 3 can also be used as a vehicle logo light or a position indicator light; the second light panel assembly 4 can be used as a turn indicator light. Those skilled in the art can connect that the first light panel assembly 3 and the second light panel assembly 4 can be set according to different functions. For example, the first light panel assembly 3 is a white light lamp, and the second light panel assembly 4 is a red light lamp, as different functional indications.

[0054] The light guide 5 is installed in the installation space of the housing 2 and is opposite to the thick-walled member 1. The first light board assembly 3 and the second light board assembly 4 are distributed at both ends of the light guide direction of the light guide 5, and the light of the first light board assembly 3 and the second light board assembly 4 can be transmitted to the thick-walled member 1 through the light guide 5. The first light board assembly 3 and the second light board assembly 4 are distributed at both ends of the light guide 5, and the light guide 5 can be used to guide the light sources of the first light board assembly 3 and the second light board assembly 4 respectively. It can be understood that the first light board assembly 3 and the second light board assembly 4 with different functions can both emit light through the light guide 5 through the thick-walled member 1.

[0055] From the above description, it can be seen that in the multifunctional light-emitting module of the present application, by setting a first lamp board assembly 3 and a second lamp board assembly 4 with different functions, the multifunctionality of the light-emitting module is realized while reducing the number of lamp beads integrated in each lamp board assembly, that is, the functions are made independent, the density of the lamp beads on the lamp board is reduced, and the heat accumulation is alleviated, which is beneficial to ensure the service life of the multifunctional light-emitting module.

[0056] Combination Figure 3 and Figure 4 The housing 2 in the illustrated embodiment includes a decorative frame 21 and a bracket 22 .

[0057] Among them, the middle position of the decorative frame 21 has a mounting hole 211 that penetrates the interior of the decorative frame 21, and the end of the decorative frame 21 has a connecting platform 212; the middle position of the bracket 22 has an avoidance groove 221 for installing the light guide 5, and the end has a positioning rod 222. The connecting platform 212 at the end of the decorative frame 21 is connected to the positioning rod 222 at the end of the bracket 22, and is threadedly connected using a screw. An installation space is formed between the decorative frame 21 and the bracket 22. The thick-walled component 1 is installed in the installation space, and the light-emitting surface of the thick-walled component 1 is exposed to the mounting hole 211. The shape and size of the mounting hole 211 can be set according to different needs, and the shape and size of the decorative frame 21 and the bracket 22 are not limited.

[0058] like Figures 5 to 8 The first lamp board assembly 3 includes: a first lamp board 31 and a first heat sink 32 .

[0059] The first lamp board 31 is provided with a first lamp bead and a control element, and the first lamp bead is connected to the wiring harness 6 so as to control and power the first lamp bead using the wiring harness. The first radiator 32 is connected to the first lamp board 31, including but not limited to bonding, clamping or threading, and the first radiator 32 is used to dissipate the heat generated by the first lamp board 31 when it is working.

[0060] Herein, the brightness and color of the first lamp bead can be set according to the function of the first lamp panel assembly 3 .

[0061] For example, when the first light panel assembly 3 is used as a daytime running light and a position indicator light, the brightness of the first lamp bead can be set to be adjustable, and the adjustment of the brightness of the first lamp bead can be achieved by changing the current of the first lamp bead. When the vehicle is driving during the day, a large current can be provided to the first lamp bead, the brightness of the first lamp bead is relatively strong, and the first light panel assembly 3 is used as a daytime running light. When the vehicle is driving at night, a smaller current can be provided to the first lamp bead, the brightness of the first lamp bead is reduced, and the first light panel assembly 3 is used as a position indicator light.

[0062] The second lamp board assembly 4 includes: a second lamp board 41 and a second heat sink 42 .

[0063] The second lamp board 41 is provided with a second lamp bead, and the second lamp bead is connected to a wiring harness. For example, the first lamp bead and the second lamp bead are connected to different wiring harnesses, so as to control the start and stop of the first lamp board 31 and the second lamp board 41 separately. According to the function of the second lamp board assembly 4, the color or brightness of the second lamp bead can be set. For example, when the second lamp board assembly 4 is a turn indicator, the second lamp bead is red.

[0064] The second lamp board 41 is connected to the second radiator 42 for dissipating heat from the second lamp board 41. In the present application, the first lamp board 31 and the second lamp board 41 dissipate heat separately, which can further improve the heat dissipation effect of the two lamp boards and ensure the service life of the multifunctional light-emitting module.

[0065] In some embodiments, the light guide 5 is a light-guiding optical fiber. The light-guiding efficiency is high and the light uniformity is high, which is beneficial to improving the light uniformity of the headlight. The optical fiber is a cylindrical structure with a certain length, and the light is transmitted along the axis direction of the optical fiber. Based on this, Figure 5 The first light board assembly 3 and the second light board assembly 4 are distributed at both ends of the optical fiber axis direction, and the two ends of the light guide 5 are respectively fixed to the first light board assembly 3 and the second light board assembly 4, so that the first light board assembly 3 and the second light board assembly 4 can both guide light through the optical fiber.

[0066] Exemplarily, one end of the light guide 5 is connected to the first light board 31, and the first lamp beads on the first light board 31 are opposite to the light guide 5, and the other end is connected to the second light board 41, and the second lamp beads on the second light board 41 are opposite to the light guide 5. The first heat sink 32 is located on a side of the first light board 31 away from the light guide 5, and the second heat sink 42 is located on a side of the second light board 41 away from the light guide 5.

[0067] Combination Figure 7 As shown, both ends of the thick-walled component 1 are connected to the first heat sink 32 and the second heat sink 42 respectively, and the thick-walled component 1 has a clamping component 11 on one side close to the light guide 5 , by which the light guide 5 and the thick-walled component 1 can be clamped and connected.

[0068] The light guide 5 has optical teeth on one side away from the thick-walled member 1, and the optical teeth are used to change the total reflection angle of the light, so that the light is irradiated to the light-emitting surface of the thick-walled member 1, and then emitted into the air medium through the light-emitting surface. The arrangement position, number and reflection angle of the optical teeth can be set according to different needs, and are all within the protection range.

[0069] Exemplarily, since the first light board assembly 3 and the second light board assembly 4 are distributed at both ends of the light guide 5, the optical teeth in the present application include a first optical tooth 51 and a second optical tooth 52. The first optical tooth 51 is located at one end of the light guide 5 away from the thick-walled member 1 and close to the first light board assembly 3, and the second optical tooth 52 is located at one end of the light guide 5 away from the thick-walled member 1 and close to the second light board assembly 4, that is, along the extension direction of the light guide 5, the first optical tooth 51 is located above the middle of the light guide 5, and the second optical tooth 52 is located below the middle of the light guide 5.

[0070] The first optical tooth 51 is arranged tilted toward the first light board assembly 3, and there is no limit on the tilt angle of the first optical tooth 51. The second optical tooth 52 is arranged tilted toward the second light board assembly 4, and it can be understood that the tilt directions of the first optical tooth 51 and the second optical tooth 52 are opposite, and illustratively, the tilt angles of the first optical tooth 51 and the second optical tooth 52 are the same.

[0071] In addition, the present application also discloses a vehicle lamp, including a multifunctional light-emitting module, wherein the multifunctional light-emitting module is the multifunctional light-emitting module disclosed in the above embodiment. Therefore, the vehicle lamp with the multifunctional light-emitting module also has all the above-mentioned technical effects, which will not be repeated here.
