DETAILED DESCRIPTION
[0029] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0030] In the present disclosure, when referring to the drawings in the following description, the same reference numerals in different drawings represent the same elements. It should be understood by those skilled in the art that the above definitions are only used to explain and illustrate the present disclosure and should not be construed as limiting the present disclosure.
[0031] According to the specific implementation of the present disclosure, Figures 1 to 7 As shown, a vehicle lamp is provided, which includes a light guide bar 1, a light source and a light-transmitting heat-insulating member 2. The light-transmitting heat-insulating member 2 is arranged between the light guide bar 1 and the light source to isolate the light guide bar 1 and the light source and transmit the light emitted by the light source to the light guide bar 1.
[0032] Through the above technical solution, by arranging the light-transmitting heat-insulating member 2 between the light guide bar 1 and the light source, the light emitted by the light source can first enter one side of the light-transmitting heat-insulating member 2, and be emitted from the other end of the light-transmitting heat-insulating member 2, and enter the light-incident end of the light guide bar 1, thereby completing the light transmission between the light source and the light guide bar 1. Therefore, by arranging the light-transmitting heat-insulating member 2 to transmit the light emitted by the light source to the light guide bar 1, the heat generated by the light source's own light emission and the light source's direct irradiation of the light guide bar 1 can be reduced and transmitted to the light guide bar 1. In this way, the temperature of the light-incident end of the light guide bar 1 is reduced, thereby reducing the risk of short-term ablation and aging of the light guide bar 1. In addition, by arranging the light-transmitting heat-insulating member 2 between the light source and the light guide bar 1, the distance between the light-incident end of the light guide bar 1 and the light source is also increased, the intensity of the blue light is weakened, thereby reducing the risk of aging and yellowing of the light guide bar 1. Among them, the light-transmitting heat-insulating member 2 has light transmittance and heat-insulating properties, can transmit the light emitted from the light source, and can isolate heat.
[0033] In some embodiments of the present disclosure, reference Figure 1 As shown, a gap is formed between the light-transmitting heat-insulating member 2 and the light-guiding strip 1. In this way, the light-transmitting heat-insulating member 2 can be spaced apart from the light-entering end of the light-guiding strip 1, so as to avoid heat generation due to contact friction between the light-guiding strip 1 and the light-transmitting heat-insulating member 2 during the operation of the vehicle, thereby affecting the heat-insulating effect of the light-transmitting heat-insulating member 2 on the light source and the light-guiding strip 1, and affecting the service life of the light-transmitting heat-insulating member 2.
[0034] In some embodiments of the present disclosure, reference Figure 4 As shown, the light-transmitting heat-insulating member 2 can be constructed as a glass sheet. The glass sheet has high transparency and can meet the light transmission requirements between the light source and the light guide strip 1. The glass sheet is made of simple materials and is easy to process. It is easy to process into a required shape according to the gap between the light source and the light guide strip 1, and is easy to replace.
[0035] In some embodiments of the present disclosure, reference Figure 1 and Figure 2 As shown, the vehicle lamp may further include a bracket 3 and a circuit board 4, the light source is fixed to the circuit board 4, the bracket 3 is provided with a light-transmitting opening 311 and is mounted on the circuit board 4, the light-transmitting heat-insulating member 2 is mounted on the bracket 3, and the light-guiding strip 1 transmits light to the light-transmitting heat-insulating member 2 through the light-transmitting opening 311. Among them, the light source is fixedly connected to the circuit board 4 so as to provide power to the light source through the circuit board 4, the bracket 3 may support and fix the light-transmitting heat-insulating member 2 to ensure the stability of the light-transmitting heat-insulating member 2 during the operation of the vehicle, and by providing the light-transmitting opening 311 on the bracket 3, the light can pass through the light-transmitting heat-insulating member 2 and the bracket 3 at the same time, so as to avoid the bracket 3 affecting the transmission of light between the light source and the light-guiding strip 1.
[0036] In some embodiments of the present disclosure, reference Figure 2 and Figure 3As shown, the bracket 3 includes a support plate 31 and a stop plate 32 and is provided with a limiting structure 33. The support plate 31 is formed with a light-transmitting opening 311. At least two sides of the support plate 31 are connected with the stop plates 32. The stop plates 32 are arranged at an angle with the support plate 31 and form an installation space together with the support plate 31. The limiting structure 33 is used to limit the light-transmitting heat-insulating component 2 in the installation space. In this way, when the light-transmitting heat-insulating component 2 is placed in the installation space, the stop plates 32 on both sides can block the two sides of the light-transmitting heat-insulating component 2 respectively, and the limiting structure 33 can limit the light-transmitting heat-insulating component 2, so that the light-transmitting heat-insulating component 2 and the bracket 3 can be relatively fixed, thereby preventing the light-transmitting heat-insulating component 2 from sliding out of the installation space due to the shaking of the vehicle, and ensuring the installation stability of the light-transmitting heat-insulating component 2.
[0037] In addition, the bracket 3 can also be set as other structures that can support the light-transmitting heat-insulating component 2, so that the light from the light source can be transmitted through the light-transmitting heat-insulating component 2 to the light guide strip 1, and the present disclosure does not make any specific restrictions on this.
[0038] In some embodiments of the present disclosure, reference Figure 2 and Figure 3 As shown, the three sides of the support plate 31 are respectively connected to the stopper plates 32, each stopper plate 32 is respectively stopped at one side of the light-transmitting heat-insulating member 2, and the limiting structure 33 includes a buckle 331, which is hinged to the support plate 31 and limits the light-transmitting heat-insulating member 2. Among them, a stopper plate 32 can be arranged at the lower side of the support plate 31 (the directional word "lower" here corresponds to Figure 3 The light-transmitting heat-insulating member 2 is used to support the light-transmitting heat-insulating member 2 and prevent the light-transmitting heat-insulating member 2 from moving downward ( Figure 3 The three stop plates 32 are arranged relatively to each other to prevent the light-transmitting heat-insulating member 2 from shaking and sliding out of the installation space laterally. The three stop plates 32 are limited together so that the light-transmitting heat-insulating member 2 can be placed in the installation space. The buckle 331 can be hinged on the top of the support plate 31. When it is necessary to fix the light-transmitting heat-insulating member 2 to the bracket 3, the buckle 331 is opened. At this time, the light-transmitting heat-insulating member 2 can be placed in the installation space from the side of the support plate 31 where the buckle 331 is installed, and then the buckle 331 is buckled. Therefore, the buckle 331 can work together with the stop plates 32 on the three sides of the support plate 31 to limit the light-transmitting heat-insulating member 2, thereby preventing the light-transmitting heat-insulating member 2 from sliding out of the installation space due to the shaking of the vehicle and affecting the transmission of light, thereby ensuring the stability of the light-transmitting heat-insulating member 2.
[0039] In some embodiments of the present disclosure, reference Figure 2 and Figure 3As shown, the limiting structure 33 may also include a limiting arm 332. Two relatively arranged stop plates 32 are respectively connected to the limiting arms 332. Each limiting arm 332 is arranged at an angle with the corresponding stop plate 32 so as to be arranged relative to the support plate 31. The light-transmitting heat-insulating component 2 is limitedly matched with the limiting arms 332. In this way, the light-transmitting heat-insulating component 2 can be clamped between the limiting arms 332 and the support plate 31 through the limiting arms 332. The light-transmitting heat-insulating component 2 can fit with the support plate 31 and the limiting arms 332 to prevent the light-transmitting heat-insulating component 2 from shaking in the installation space and affecting the transmission of light. Figure 3 In the illustrated embodiment, one limiting arm 332 is connected to the end of the stop plate 32 and is bent from the end of the stop plate 32 toward the stop plate 32 on the other side. Another limiting arm 332 can be formed on the stop plate 32 by stamping and is bent toward the stop plate 32 on the other side, so that the light-transmitting heat-insulating component 2 placed in the installation space can be clamped between the limiting arm 332 and the support plate 31. In addition, since the limiting arm 332 is directly provided on the stop plate 32, it can be directly processed together with the stop plate 32, thereby improving the processing efficiency.
[0040] In some embodiments of the present disclosure, reference Figure 2 As shown, the vehicle lamp may further include a fastener 5, and the bracket 3 may further include a connecting ear plate 34, the connecting ear plate 34 is connected to the stop plate 32 and bent from the end of the stop plate 32, and the connecting ear plate 34 is formed with a mounting hole 341, and the fastener 5 passes through the mounting hole 341 and is fastened to the circuit board 4. In this way, by fixing the connecting ear plate 34 to the circuit board 4, the bracket 3 and the circuit board 4 can be relatively fixed, the stability of the bracket 3 is ensured, and the shaking of the bracket 3 will not cause the light-transmitting heat-insulating member 2 on the bracket 3 to shake, thereby affecting the transmission of light.
[0041] In some embodiments of the present disclosure, reference Figure 1 and Figure 2 As shown, the vehicle lamp may further include a radiator 6, and the circuit board 4 is fixed to the radiator 6. In this way, the circuit board 4 can be relatively fixed to the radiator 6, so that the bracket 3 and the light-transmitting heat-insulating member 2 installed on the bracket 3 can be relatively fixed to the radiator 6 to ensure the stability of the light-transmitting heat-insulating member 2. In addition, the light source generates a large amount of heat, and the radiator 6 can dissipate the heat emitted by the light source and the circuit board 4. Among them, the radiator 6 can be made of a metal with a high thermal conductivity so as to quickly conduct the heat of the light source and the circuit board 4 to the external environment, thereby achieving the purpose of reducing the temperature near the light source and preventing damage to the light source.
[0042] In some embodiments of the present disclosure, reference Figures 5 to 7As shown, the vehicle lamp can also include a support frame 7 and a light shield 8, the light shield 8 is connected to the support frame 7, and the light shield 8 and the support frame 7 are respectively provided with positioning grooves 9, and the two sides of the light guide bar 1 are respectively positioned in the positioning grooves 9. Among them, the outer contour of the support frame 7 is mainly determined by the structure of the lamp chamber and the remaining components. The light shield 8 is fixed on the support frame 7, and the light shield 8 can cover the light emitted from other areas other than the light-emitting surface of the light guide bar 1. Since the positioning grooves 9 are provided on the support frame 7 and the light shield 8, when the light guide bar 1 is installed on the support frame 7, the fixed position of the light guide bar 1 can be quickly positioned, and at the same time, the position of the positioning grooves 9 can be matched to achieve the assembly of the light shield 8 and the support frame 7, so that the light guide bar 1 is surrounded therein to ensure the optical effect of the light guide bar 1. Among them, the support frame 7 can be made of a material with good reflective performance, which can enhance the brightness and optical effect, and block the light emitted by the light guide bar 1 perpendicular to its own extension direction.
[0043] In some embodiments of the present disclosure, reference Figures 5 to 7 As shown, the support frame 7 is provided with a limiting groove 71, and the limiting groove 71 extends along the extension direction of the support frame 7, and the light guide bar 1 is limited in the limiting groove 71. In this way, when the light guide bar 1 is installed on the support frame 7, the limiting groove 71 can be used to fix and limit the light guide bar 1 to maintain the relative fixation between the light guide bar 1 and the support frame 7, thereby limiting the light guide area and direction of the light guide bar 1, and avoiding the light guide bar 1 slipping on the support frame 7 and affecting the light guide effect. Among them, the limiting groove 71 is provided on the support frame 7, and the local area of the limiting groove 71 is provided with a positioning groove 9, and a mounting structure is provided for the light shield 8 at the end of the support frame 7 close to the light source, and flanges can be provided on both sides of the light guide bar 1, one end of which can be fixed in the positioning groove 9, and then the light guide bar 1 can be clamped in the limiting groove 71 as a whole, and the light shield 8 can be buckled on the support frame 7, so as to achieve the light guide bar 1 Fixed on the support frame 7.
