[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.
[0026] The following combination Figures 1 to 4 The vehicle lamp of the present invention is described.
[0027] like Figures 1 to 4 As shown, the present invention provides a vehicle lamp, including a lamp holder 1, lamp beads 2, a circuit board 3, a heat sink 4 and a light guide. The lamp beads 2 are arranged on the circuit board 3, the circuit board 3 is arranged on the heat sink 4 and is tightly fitted with the heat sink 4, the lamp holder 1 is connected to the heat sink 4, and the light guide is connected to the lamp holder 1.
[0028] In the headlight provided in this embodiment, the lamp bead 2 serving as the heat source is moved from the inside of the headlight to the outside, thereby solving the heat dissipation problem of the bulb that is difficult to overcome in the traditional structure. In addition, the radiator 4 can provide a heat dissipation function for the lamp bead 2, thereby improving the heat dissipation effect. Therefore, a more efficient lamp bead 2 can be used according to actual needs to improve the lighting effect and extend the service life of the entire headlight.
[0029] In some embodiments, the heat sink 4 is disposed around the lamp beads 2 to achieve better heat dissipation effect.
[0030] In some embodiments, the radiator 4 is provided with a mounting groove 41 , and the circuit board 3 is embedded in the mounting groove 41 . The circuit board 3 can be more stably mounted on the radiator 4 , and the heat spreader can provide good heat dissipation effect for the circuit board 3 and the lamp beads 2 .
[0031] In some embodiments, the lamp holder 1 is embedded in the mounting groove 41, and the lamp bead 2 is located at the end of the lamp holder 1 away from the light guide. The light guide is used to diverge the light of the lamp bead 2 to the end away from the radiator 4. The light of the lamp bead 2 is diverged through the light guide, and the lighting effect is better.
[0032] In some embodiments, the lamp holder 1 is detachably mounted on the radiator 4 via a bayonet ring 8. Specifically, a card slot is provided on the lamp holder 1 and a card hole is provided on the radiator 4. The bayonet ring 8 can be snapped into the card slot through the card hole, thereby completing the fixation of the lamp holder 1 and the radiator 4. Both disassembly and installation are very convenient.
[0033] In some embodiments, the light guide includes a low-beam light guide tube 5 and a high-beam light guide tube 6 , and both the low-beam light guide tube 5 and the high-beam light guide tube 6 are plugged into the lamp holder 1 , making the installation more stable.
[0034] In some embodiments, the headlight also includes a reflective plate 7, which is connected to the lamp frame 1. The reflective plate 7 is used to reflect the light emitted by the low beam light guide 5. The low beam light guide 5 is used to diverge the light of the lamp bead 2 along a first direction, and the high beam light guide 6 is used to diverge the light of the lamp bead 2 along a second direction. The first direction is orthogonal to the second direction. Specifically, the high beam light guide 6 diverges the light of the lamp bead 2 in a horizontal direction, that is, toward the front of the vehicle, thereby achieving the lighting effect required for the high beam, and the low beam light guide 5 diverges the light of the lamp bead 2 in directions such as up, down, left, and right, thereby achieving the lighting effect required for the low beam.
[0035] Specifically, the reflector 7 is detachably mounted on the lamp holder 1 by screws 9 , and is very convenient to disassemble or install.
[0036] In some embodiments, both the low-beam light guide 5 and the high-beam light guide 6 are curved, which can more conveniently achieve corresponding lighting effects.
[0037] In some embodiments, the ends of the low-beam light guide tube 5 and the high-beam light guide tube 6 are both curved surfaces, and the light scattering angles of the low-beam light guide tube 5 and the high-beam light guide tube 6 are both 140 degrees. Through such a design, the light beam of the high-beam light guide tube 6 can be more concentrated and the lighting effect can be better.
[0038] In some embodiments, the light guide member is made of transparent glass or light-guiding plastic optical fiber, which has a good light-guiding effect, thereby achieving a better lighting effect.
[0039] In some embodiments, the distance between the lamp bead 2 and the light guide is 0.5 cm, which can better spread the light emitted by the lamp bead 2.
[0040] In some embodiments, the lamp beads 2 are LED lamp beads 2 , which have good lighting effects.
[0041] In some embodiments, the heat sink 4 is provided with heat dissipation fins 42 , which has a good heat dissipation effect.
