Description

Technical Field

[0001] The utility model relates to the technical field of automotive lighting equipment, in particular to a direct plug-in mini-structured vehicle lamp. Background Art

[0002] When the existing automotive bulbs are in use, as the power of the bulbs increases, the heat dissipated by the bulbs also increases. When the bulbs work in a high-temperature environment for a long time, it is easy to cause too fast light decay, reducing their heat dissipation efficiency and service life. However, for the existing structured vehicle lamps, their heat dissipation structural parts mostly dissipate heat through the air-flow heat dissipation method, and the heat dissipation efficiency is limited, unable to meet the long-term and high-temperature use requirements of the bulbs. Summary of the Utility Model

[0003] Aiming at the technical problem of poor heat dissipation effect of the existing vehicle lamps, the utility model provides a direct plug-in mini-structured vehicle lamp.

[0005] A direct plug-in mini-structured vehicle lamp includes a heat dissipation housing, a heat conduction member fixed to the heat dissipation housing, a circuit board fixed in the heat dissipation housing, at least one lamp bead fixed to the heat conduction member and electrically connected to the circuit board, a fan installed on the heat dissipation housing, and a plug installed on the heat dissipation housing. The fan is arranged facing the heat conduction member and is electrically connected to the circuit board, and the plug is electrically connected to the circuit board.

[0006] The beneficial effect of the utility model is that the heat conduction member and the circuit board are directly fixedly connected to the heat dissipation housing to form an integrated installation structure, so as to realize rapid heat dissipation through object transmission and utilize the heat dissipation housing. At the same time, the fan is used to directly dissipate heat from the heat conduction member and the circuit board to realize air-cooled heat dissipation, improve the heat dissipation effect of the product, and solve the technical problem of poor heat dissipation effect of the existing vehicle lamps.

[0007] On the basis of the above technical solution, the utility model can be further improved as follows.

[0008] Further, the heat conduction member has a tubular structure, one end is fixedly connected inside the heat dissipation housing, and the other end extends outside the heat dissipation housing. There are at least four lamp beads arranged circumferentially and evenly on the outside of the other end of the heat conduction member.

[0009] The beneficial effect of adopting the above further solution is that multiple lamp beads circumferentially and evenly distributed on the heat conduction member are used to realize four-sided light emission, ensuring that there are no dark areas in the lighting.

[0010] Further, a reflective cap is detachably connected to the end of the other end of the heat conduction member.

[0011] The beneficial effects of adopting the above further scheme are as follows: The light emitted by the lamp beads can be reflected by the reflective cap, making it more concentrated and directional, improving the lighting efficiency. At the same time, by reflecting the light, the light becomes softer and more uniform, reducing the risk of glare and improving the safety of use.

[0012] Further, the circuit board is arranged on the side wall of the heat conducting member and extends along the length direction of the heat conducting member. One end of the circuit board in the length direction faces the fan and is electrically connected to the plug.

[0013] The beneficial effects of adopting the above further scheme are as follows: The circuit board is integrally arranged on the side wall of the heat conducting member to improve the heat conduction efficiency.

[0014] Further, the circuit board is installed with an IC module.

[0015] The beneficial effects of adopting the above further scheme are as follows: The IC module can effectively avoid the interference of the LED light source to the vehicle computer board and various auxiliary devices. At the same time, it can provide an intelligent decoding mode, without the need for an external decoding group, and can achieve a wireless direct plug-in installation.

[0016] Further, the heat conducting member has a plate-like structure and is fixedly connected inside the heat dissipation housing. There are at least two lamp beads arranged on both sides of the heat conducting member in the thickness direction, and the heat dissipation housing is provided with light openings corresponding to the positions of the respective lamp beads in a penetrating manner.

[0017] The beneficial effects of adopting the above further scheme are as follows: The heat conducting member is integrally fixed inside the heat dissipation housing, and the heat dissipation housing is used for direct heat dissipation.

[0018] Further, the circuit board is installed at one end of the heat conducting member and is located between the heat conducting member and the fan.

[0019] The beneficial effects of adopting the above further scheme are as follows: The rapid heat dissipation of the circuit board can be realized through the fan.

[0020] Further, the heat dissipation housing includes a first housing and a second housing that are detachably connected to each other. A heat dissipation groove and an air outlet that communicate with each other are provided at the connection of the first housing and the second housing. The heat conducting member is installed in the heat dissipation groove, and the fan is installed in the air outlet.

[0021] The beneficial effects of adopting the above further scheme are as follows: The first housing and the second housing are detachably connected to each other, so as to quickly disassemble and assemble structural components such as the heat conducting member and the fan.

[0022] Further, a protective cover for enclosing the fan in the air outlet is detachably connected to the heat dissipation housing.

[0023] The beneficial effect of adopting the above further solution is that the fan can be enclosed within the air outlet by the protective cover, forming a protective effect on the fan.

[0024] Further, a chuck is detachably sleeved on the outer side of the first housing and / or the second housing.
