[0002] In the prior art, an LED vehicle lamp generally includes a bottom plate, an LED light source and a light guide bar. The light guide bar is arranged on the bottom plate, and the LED light source is arranged at one end of the bottom plate to convert a point light source into a surface light source. However, such a vehicle lamp has a single structure and a single lighting effect.

[0003] Therefore, how to improve the lighting effect of the vehicle lamp is a technical problem that those skilled in the art need to solve at present. Summary of the Utility Model

[0004] In view of this, the first object of the utility model is to provide a light-emitting component to improve the lighting effect of the vehicle lamp;

[0005] In order to achieve the above first object, the utility model provides the following technical solutions:

[0006] A light-emitting component includes a motion mechanism, a light-shielding sheet, one or more light guide bars, a light guide bar bracket and a light source. The light guide bar bracket is used to fix one or more light guide bars. When the number of light guide bars is two or more, there is a gap between adjacent light guide bars, and adjacent light guide bars are connected end to end. The light-shielding sheet is connected to the motion mechanism, and the number of light-shielding sheets is the same as the number of gaps. The motion mechanism is used to drive the light-shielding sheet to insert into and / or disengage from the gap. The light source is arranged at the end of the light-emitting component.

[0007] Optionally, in the above light-emitting component, the light-emitting component further includes a controller, and the controller is electrically connected to the motion mechanism and the light source.

[0008] Optionally, in the above light-emitting component, the motion mechanism further includes a first stepping motor, a gear and a rack. The first stepping motor is electrically connected to the controller. The output shaft of the first stepping motor is connected to the gear. The gear meshes with the rack. The rack is connected to the light-shielding sheet and is used to drive the light-shielding sheet to perform a linear reciprocating motion.

[0009] Optionally, in the above light-emitting component, the motion mechanism further includes a second stepping motor. The output shaft of the second stepping motor is connected to the light-shielding sheet and is used to drive the light-shielding sheet to perform a rotational motion.

[0010] Optionally, in the above light-emitting component, the light-emitting component further includes a PCB board, and one or more light sources are arranged on the PCB board;

[0011] The light source is an LED light source.

By controlling the time and interval of the light-shielding sheet extending through the motion mechanism, diverse lighting effects can be achieved. For example, when the motion mechanism controls all the light-shielding sheets to be inserted into the gaps between the connected light guide bars, starting from the light source, the brightness of multiple light guide bars decreases in sequence to achieve a flowing water-like lighting effect. When the motion mechanism controls some light-shielding sheets to be alternately inserted into the gaps between the connected light guide bars, starting from the light source, the brightness of multiple light guide bars changes between bright and dark, forming an irregular lighting effect.

[0021] For the vehicle lamp provided by the present utility model, due to having the above-mentioned light-emitting component, it has all the technical effects of the above-mentioned light-emitting component, which will not be elaborated herein again. Description of the Drawings

[0022] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the following drawings are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0024] Among them:

[0025] The motion mechanism 100, the light-shielding sheet 200, the light guide bar bracket 300, the PCB board 400, the light source 500, and the light guide bar 600. Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0027] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "top surface", "bottom surface", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0028] Such as Figure 1As shown, the light-emitting component disclosed by the present utility model includes a motion mechanism 100, a light-shielding sheet 200, one or more light guide bars 600, a light guide bar bracket 300, and a light source 500. The light guide bar bracket 300 is used to fix one or more light guide bars 600. When the number of light guide bars 600 is two or more, there is a gap between adjacent light guide bars 600, and adjacent light guide bars 600 are connected end to end. The light-shielding sheet 200 is connected to the motion mechanism 100, and the number of light-shielding sheets 200 is the same as the number of gaps. The motion mechanism 100 is used to drive the light-shielding sheet 200 to insert into and / or disengage from the gaps. The light source 500 is arranged at the end of the light-emitting component. Specifically, the light-shielding sheet 200 is made of a semi-transparent material, and the operator can change its light transmittance according to the usage requirements, thereby changing the lighting brightness of the light guide bar 600. When the light-emitting component provided by the present utility model is in use, the light source 500 is arranged at the end of the light-emitting component to light up the light guide bar 600, and a diverse lighting effect is achieved by controlling the time and interval of the light-shielding sheet 200 extending out through the motion mechanism 100. For example, when the motion mechanism 100 controls all the light-shielding sheets 200 to insert into the gaps between the adjacent light guide bars 600, starting from the light source 500, the brightness of multiple light guide bars 600 decreases in sequence to achieve a flowing lighting effect. When the motion mechanism 100 controls some of the light-shielding sheets 200 to alternately insert into the gaps between the adjacent light guide bars 600, starting from the light source 500, the brightness of multiple light guide bars 600 changes between bright and dark, forming an irregular lighting effect. Therefore, by arranging the motion mechanism 100 and the light-shielding sheet 200, the flexible lighting of the light-emitting component is achieved, and a diverse lighting effect of the vehicle lamp is formed.

[0029] To optimize the above technical solution, the light-emitting component further includes a controller, and the controller is electrically connected to the motion mechanism 100 and the light source 500. Specifically, the controller is used to control the transmission of the motion mechanism 100, and the lighting and extinguishing of the light source 500. When in use, the controller controls the motion mechanism 100 to push out or retract a single or multiple light-shielding plates, controls the lighting and extinguishing of the light source 500, the time for pushing out or retracting a single or multiple light-shielding plates, and the time for controlling the lighting and extinguishing of the light source 500, so as to achieve the diversification of the light-emitting shape of the light-emitting component, thereby improving the lighting effect of the vehicle lamp.

[0030] In some embodiments of the present utility model, the motion mechanism 100 further includes a first stepping motor, a gear, and a rack. The first stepping motor is electrically connected to the controller. The output shaft of the first stepping motor is connected to the gear, the gear meshes with the rack, and the rack is connected to the light shielding sheet 200 for driving the light shielding sheet 200 to perform a linear reciprocating motion. When in use, the controller controls the operation of the first stepping motor. The rotation of the output shaft of the first stepping motor drives the gear to rotate, the rotation of the gear drives the rack to perform a linear reciprocating motion, and the rack drives the light shielding sheet 200 to perform a linear reciprocating motion, thereby realizing the light shielding sheet 200 to extend into or disengage from the gap. When the light shielding sheet 200 extends into the gap, the light transmitted from the light incident side of one light guide bar 600 to the light incident side of another light guide bar 600 becomes weaker, so that the brightness of the next light guide bar 600 can be controlled. Such an arrangement realizes the linear reciprocating motion of the light shielding sheet 200 at the gap, improving the lighting effect of the vehicle lamp.

[0031] In other embodiments of the present utility model, the motion mechanism 100 further includes a second stepping motor. The output shaft of the second stepping motor is connected to the light shielding sheet 200 for driving the light shielding sheet 200 to perform a rotational motion. When in use, an installation hole is provided on the light shielding sheet 200. The output shaft of the second stepping motor extends into the installation hole and is perpendicularly and fixedly connected to the light shielding sheet 200. When the controller controls the operation of the second stepping motor, the rotation of the output shaft of the second stepping motor drives the light shielding sheet 200 to rotate around the installation hole, thereby realizing the light shielding sheet 200 to rotate into or out of the gap, achieving the purpose of blocking light, and thus controlling the brightness of the next light guide bar 600. Such an arrangement realizes the rotational motion of the light shielding sheet 200 at the gap, simplifies the structure of the light emitting component, and improves the lighting effect of the vehicle lamp.

[0032] In other embodiments of the present utility model, the motion mechanism 100 may further include a third stepping motor and a linkage mechanism. The third stepping motor is connected to the light shielding sheet 200 through the linkage mechanism. By changing the arrangement angle and position of the linkage mechanism, the angle of the light shielding sheet 200 extending into and disengaging from the gap can be adjusted, thereby improving the lighting effect of the vehicle lamp.

[0033] To optimize the above technical solution, the light emitting component further includes a PCB board 400. One or more light sources 500 are arranged on the PCB board 400, and the light sources 500 are LED light sources 500. Specifically, the light sources 500 on the PCB board 400 emit light to the light guide bar 600. The controller can control the lighting of a single or multiple light sources 500 to control the intensity of the initial light, thereby adjusting the brightness of the light guide bar 600 on the side close to the light source 500 at the initial stage, so that the overall brightness of the light emitting component is adjustable, thereby realizing the diversification of the lighting effect of the vehicle lamp.

[0034] To optimize the above technical solution, the PCB board 400 is arranged opposite to both ends of the light emitting component, or the PCB board 400 is arranged on one side of the light emitting component.

[0035] Specifically, when the PCB board 400 is relatively arranged at both ends of the light-emitting component, the light-emitting component has light input from both sides, that is, there is light input on both sides of the whole of multiple light guide bars 600 connected end to end. At this time, by changing the positions of different light-shielding plates, different lighting effects can be achieved. For example, when the number of light guide bars 600 is three, the number of gaps and light-shielding plates is two. At this time, the moving mechanism 100 drives the two light-shielding plates to simultaneously extend into the gaps respectively, and the whole light-emitting component forms a lighting effect with strong light at both ends and weak light in the middle; when the number of light guide bars 600 is five, the number of gaps and light-shielding plates is four. At this time, the moving mechanism 100 drives the two left light-shielding plates to extend into the gaps, one right light-shielding plate extends into the gap, and one middle light-shielding plate disengages from the gap, and the whole light-emitting component forms a lighting effect with weak light on the left and strong light on the right.

[0036] Specifically, when the PCB board 400 is arranged on one side of the light-emitting component, the light-emitting component has light input from one side, that is, when all its light-shielding plates extend into the gaps, it presents a lighting effect that gradually weakens from left to right. If it is changed to control each light-shielding plate to extend into the gaps in sequence, a flowing water type of lighting effect that lights up one by one will be generated. Such an arrangement reduces the number of PCB boards 400 and light sources 500, simplifies the overall structure of the light-emitting component, saves production costs, and can also achieve diversified lighting effects.

[0037] The number of light sources 500, the arrangement position of the PCB board 400, the lighting and extinguishing of a single light source 500, the number and arrangement position of the light guide bars 600, and the insertion and disengagement time of the light-shielding plates are all variables for changing the lighting effect. Operators can control to form a variety of lighting effects, which will not be elaborated here.

[0038] To optimize the above technical solution, the light guide bar bracket 300 is provided with a card slot, and the light guide bar 600 is clamped inside the card slot. Specifically, the light guide bar 600 and the light guide bar bracket 300 are clamped. The slot opening of the card slot is smaller than the diameter of the light guide bar 600, and the distance between the slot bottom and the slot opening of the card slot is greater than the radius of the light guide bar 600, so that when the card slot is clamped with the light guide bar 600, at least one-half of the light guide bar 600 is arranged inside the card slot, thereby improving the stability of the light guide bar 600.

[0039] In some embodiments of the present utility model, the light guide bar bracket 300 is of an integral design. Specifically, when the light guide bar bracket 300 is of an integral design, a card slot can be provided, and multiple light guide bars 600 are segmented and clamped inside the card slot. When the light-shielding plate is inserted into the gap, the bottom of the light-shielding plate falls on the slot opening of the card slot, thereby forming light shielding. Such an arrangement can reduce the production cost of the light guide bar bracket 300, improve the production efficiency of the light guide bar bracket 300, and ensure the consistency and stability of the structure of the light-emitting component.

[0040] In some other embodiments of the present utility model, the light guide bar bracket 300 is of a split design. Specifically, when the light guide bar bracket 300 is of a split design, the light guide bar brackets 300 are connected end to end, and there is a gap between two adjacent light guide bar brackets 300 to accommodate the light blocking plate. The top of the light guide bar bracket 300 is used to snap the light guide bar 600, and the bottom can be used to arrange the connecting part. The connecting parts of two adjacent light guide bar brackets 300 are connected to each other. The forms of the connecting parts include but are not limited to plugging, bolt connection, welding, etc. Such an arrangement can change the number of light guide bar brackets 300, thereby flexibly changing the overall structure of the light-emitting component, making it present structural shapes such as strip, square, triangle, etc., and further realizing the diversification of the lighting effect of the vehicle lamp.

[0041] The present utility model also discloses a vehicle lamp, which includes a vehicle lamp body and the light-emitting component as described in any one of the above. Specifically, multiple light-emitting components can be installed on the vehicle lamp at the same time. The multiple light-emitting components can be arranged vertically side by side, horizontally side by side, or inclined to each other, so as to form various lighting shapes. Specifically, the above-mentioned controller can be connected to the control structure of the vehicle lamp body, or can be connected to the control structure of the vehicle body to which the vehicle lamp is connected, as long as it can send instructions to the motion mechanism 100. Since the above-mentioned light-emitting component has the above effects, the vehicle lamp including the light-emitting component has corresponding effects, which will not be elaborated here.

[0044] (2) It has high operability and is flexible to use;
