[0024] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.
[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.
[0026] Please refer to Figures 1-5 The present application provides the following technical solutions:
[0027] Embodiment one, refer to Figure 1 A bifurcated special-shaped energy-saving light guide assembly, comprising a light guide assembly 1, the light guide assembly 1 is used to realize the output of light, and the light guide assembly 1 is provided with a lamp bead assembly 2 on one side.
[0028] Among them, the light generated by the lamp bead assembly 2 can be conducted along the light guide assembly 1, and finally form a coherent and soft light strip effect.
[0029] Refer to Figure 2 The light guide assembly 1 comprises a first light guide part 11, a second light guide part 12 and a third light guide part 13 in sequence, the first light guide part 11, the second light guide part 12 and the third light guide part 13 are combined to form a Y-shaped light guide structure, the length of the second light guide part 12 is less than the length of the third light guide part 13, and the first light guide part 11, the second light guide part 12 and the third light guide part 13 are integrally formed.
[0030] Refer to Figure 3 The lamp bead assembly 2 comprises a lamp holder 21, the lamp holder 21 is provided with a lamp bead body 22, the lamp bead body 22 corresponds to the end of the light guide assembly 1, and the lamp holder 21 is further provided with a mounting hole for fixing.
[0031] Refer to Figure 2 And Figure 4 A first mounting seat 14 is arranged on the side wall of the first light guide part 11, the first mounting seat 14 is used to fix the first light guide part 11, and a first light distribution tooth group 17 is arranged on one side of the first light guide part 11.
[0032] See Figure 2 and Figure 4 A second mounting base 15 is provided on the side wall of the second light guide 12. The second mounting base 15 is used to fix the second light guide 12. A second light distribution tooth group 18 is provided on one side of the second light guide 12.
[0033] See Figure 2 and Figure 4 A third mounting base 16 is provided at the end of the third light guide section 13. The third mounting base 16 is used to fix the third light guide section 13. A third light distribution tooth group 19 is provided on one side of the third light guide section 13.
[0034] The second light distribution tooth group 18 and the third light distribution tooth group 19 are arranged sequentially along the Y-shaped light guide structure. The arrangement of the first light distribution tooth group 17, the second light distribution tooth group 18, and the third light distribution tooth group 19 provides a basis for the transmission of light and facilitates the uniform transmission of light.
[0035] The mounting holes facilitate the installation of the lamp holder 21 onto the lamp housing of the lamp, making it easier to fix the lamp holder 21, reducing the possibility of the lamp bead assembly 2 shaking during use, and improving the stability of the lamp.
[0036] The second mounting base 15 and the third mounting base 16 are respectively disposed at the positions of the first light guide 11, the second light guide 12, and the third light guide 13. The first light guide 11, the second light guide 12, and the third light guide 13 are fixedly installed on the lamp by bolts through the first mounting base 14, the second mounting base 15, and the third mounting base 16. The partitioned fixing can further increase the stability of the light guide assembly 1, reduce the shaking of the light guide assembly 1 during use, and improve the stability of the lamp.
[0037] The end of the first light guide 11 corresponds to the lamp bead body 22. The first light guide 11, the second light guide 12, and the third light guide 13 are all light guide strips. The light guide strips are made of highly transparent optical plastic. After the light enters, it will propagate in a straight line inside due to total internal reflection.
[0038] The light transmission process is as follows:
[0039] After the lamp bead body 22 emits light, the light directly enters the first light guide section 11 and propagates along the length direction within the first light guide section 11. When the light propagates along the first light guide section 11 to the Y-shaped bifurcation point, the light is guided to naturally split into the second light guide section 12 and the third light guide section 13. At the same time, a first light distribution tooth group 17, a second light distribution tooth group 18, and a third light distribution tooth group 19 are respectively provided on one side of the first light guide section 11, the second light guide section 12, and the third light guide section 13. The first light distribution tooth group 17, the second light distribution tooth group 18, and the third light distribution tooth group 19 change the interface morphology of light propagation, directly destroy the total internal reflection condition, and allow the light that originally propagated inside to be refracted out from the tooth-shaped area and converted into visible light, thus realizing the transmission of light.
[0040] In addition, the design of the light distribution teeth needs to be combined with the light source. The first light guide 11 is close to the light source lamp bead body 22, and the second light guide 12 and the third light guide 13 are at the branch position. Therefore, the light near the first light guide 11 is stronger, and the density of the first light distribution teeth 17 located on the side of the first light guide 11 is lower to avoid the light transition to the outlet and cause local bright spots. The second light guide 12 and the third light guide 13 are in the branch area, and the light is weaker. Therefore, the density of the second light distribution teeth 18 at the second light guide 12 and the third light distribution teeth 19 at the third light guide 13 is higher to fully outlet the remaining optical fiber and make up for the light efficiency attenuation. In the area near the bifurcation point of the first light guide 11 close to the second light guide 12 and the third light guide 13, the density of the teeth is designed to be transitional so that the light of the two branches is connected naturally without obvious light and dark boundaries.
[0041] This design, through the diversion function of the Y-shaped structure and the light control function of the light distribution teeth, allows the light of a single LED to break through the limitation of single-point emission and achieve coverage of multi-branch areas, reducing the cost, energy consumption and the possibility of consistency problems in multi-LED designs.
[0042] The specific structure of the first light guide section 11 is as follows:
[0043] See Figure 3 and Figure 5 The first light guide part 11 includes a first connecting part 111, one end of which is correspondingly disposed to the lamp bead body 22, and the other end of the first connecting part 111 is connected to a second connecting part 112.
[0044] See Figure 3 and Figure 5 A first mounting base 14 is provided on the side wall of the second connecting part 112.
[0045] See Figure 3 and Figure 5The second connecting part 112 is connected to a third connecting part 113 and a fourth connecting part 114 at the end away from the first connecting part 111. The third connecting part 113 and the fourth connecting part 114 are arranged in a bifurcated structure, and the included angle between the third connecting part 113 and the fourth connecting part 114 is 60°.
[0046] See Figure 3 and Figure 5 The end of the third connecting part 113 away from the second connecting part 112 is connected to the second light guide part 12, and the end of the fourth connecting part 114 away from the second connecting part 112 is connected to the third light guide part 13.
[0047] An arc transition zone is provided at the connection position between the first connecting part 111 and the second connecting part 112. The arc transition zone makes the light propagation smoother. The arc transition can avoid the light from being lost or scattered due to the sudden change of total internal reflection conditions at the right-angle connection. When the light propagates on the arc surface, it can travel more smoothly along the light guide path, reduce the number of reflections, and improve the light transmission efficiency.
[0048] The first connecting part 111 corresponds to the lamp bead and belongs to the light distribution tooth group in the near light input area. It has a low density and shallow tooth shape. The purpose is to reduce the excessive output of light at the near source end, avoid bright spots, and at the same time ensure that the light can be efficiently transmitted to the far end.
[0049] The second connecting part 112 is located in the straight section area of the light guide strip. The light distribution tooth group has a uniform density and regular tooth shape. Its function is to maintain uniform light output when the light propagates in the straight section, form a continuous light band, and ensure the consistency of light emission in this area.
[0050] The third connecting part 113 and the fourth connecting part 114 are located in the bifurcation transition area. The density of the light distribution tooth group is slightly higher and the tooth shape is optimized. By increasing the density, the light propagation loss at the bend is compensated, and the tooth surface angle is adjusted to guide the light to turn smoothly and avoid dark areas or scattered light patterns.
[0051] The 60° angle between the third connecting part 113 and the fourth connecting part 114 allows for a more rational reflection and refraction path of light at the bifurcation point, reducing light loss at the bifurcation point and improving the efficiency of light transmission to both branches. This ensures that both branches receive sufficient light for emission. In addition, the angle setting helps to achieve symmetry in the light output of the two branches. This angle can better adapt to the internal spatial layout of the headlight. Within the limited space of the lamp cavity, the bifurcation structure of the light guide strip can meet optical requirements and be coordinated with other headlight components, thus optimizing the overall structural design of the headlight.
[0052] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
