[0004] As living standards improve, many families choose cars as their daily mode of transportation. With the continuous development of the automotive industry, the demand for car lighting accessories is increasing. As an important component of a car, car lights can be called the eyes of the car, and they play an irreplaceable role in ensuring driving safety, especially in bad weather and at night.
[0005] Existing automotive lights typically have an adapter board on the light source board assembly. The leads that provide power to the power driver and the light-emitting units on the light source board need to be connected to the adapter board. Then, two wires (positive and negative wires) are led out from the adapter board. If the automotive light also has a heat sink, more soldering wires and interfaces are needed to connect to the adapter board, making the assembly process of the automotive light more complicated and difficult. At the same time, the large number of soldering wires can easily lead to poor contact, causing the automotive light to malfunction. [Utility Model Content]

Detailed Implementation Methods
[0036] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0037] First embodiment:
[0038] Please refer to Figures 1 to 4 As shown, this embodiment proposes an automotive lamp, including a lamp housing 10 and a power plug 30 for electrical connection with the lamp power supply. The lamp housing 10 houses a light source board assembly 20, and the power plug 30 has at least one pin 31 for electrical connection with the light source board assembly 20, making the light source board assembly 20 and the power plug 30 an integrated optoelectronic structure. This integrated optoelectronic structure of the light source board assembly 20 and the power plug 30 reduces the number of external connection wires and interfaces, simplifies circuit connections, and reduces the risk of failure due to poor connections or loose interfaces. It also simplifies the assembly process of the automotive lamp and reduces production costs.
[0039] Furthermore, as a preferred embodiment of this solution and not a limitation, the power plug 30 has at least one pin 31, and the power plug 30 is provided with at least one conductive tab 32 for inserting into the vehicle light power socket, and the number of pins 31 is equal to the number of conductive tabs 32.
[0040] In this embodiment, the power plug 30 has two pins 31 and two symmetrically arranged conductive tabs 32. Furthermore, the power plug 30 can be a straight-insertion type or a side-insertion type, for example... Figures 1 to 2 As shown, the power plug 30 is a straight-plug type, for example, Figures 3 to 4 As shown, the power plug 30 is a side-plug type.
[0041] In this embodiment, a power plug replaces the traditional adapter board, reducing the number of external connections and interfaces, lowering the failure rate caused by poor contact or loose interfaces, and simplifying the assembly process of automotive lights; at the same time, the power plug can be quickly plugged in and out, making the installation and removal of automotive lights more convenient.
[0042] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the light source board assembly 20 includes a light source substrate 21, on which at least one interface 22 for electrical connection with the pin 31 is provided;
[0043] Among them, such as Figures 1 to 2 As shown, the light source substrate 21 has four interfaces 24 on the side near the power plug 30 and four interfaces 24 on the side away from the power plug 30.
[0044] like Figures 3 to 4 As shown, the light source substrate 21 has eight interfaces 24 on the side near the power plug 30.
[0045] In this embodiment, the pins of the power plug are connected to the interface on the light source substrate, which enables the light source board assembly and the power plug to be an integrated optoelectronic structure without the need for additional wiring. This simplifies the internal circuit connection structure of the automotive lamp. At the same time, this snap-fit or latch-fitting method with the interface also provides better stability and avoids poor contact caused by loosening. Through the interface, the power plug can be quickly inserted into or removed from the light source substrate, simplifying the assembly and maintenance process of the automotive lamp.
[0046] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the light source substrate 21 is also provided with a light source part 23 and a light-emitting chip 24 for controlling the light emission of the light source part 23;
[0047] The light-emitting chip 24 can be disposed on the side near the power plug 30, or at other positions on the light source substrate 21. The specific position can be flexibly adjusted according to actual design requirements.
[0048] In this embodiment, both the light-emitting chip and the light source are mounted on the light source substrate, which facilitates thermal management and ensures that the temperature of both the light-emitting chip and the light source is controlled within the operating range, thus extending their service life. At the same time, the short signal transmission path enables a faster response speed, making the turning on and brightness adjustment of the car lights more rapid and sensitive.
[0049] Furthermore, as a preferred embodiment of this solution and not a limitation, the light source board assembly 20 is provided with at least one conductive component for conducting electricity, and the conductive component 26 is a single-PIN U-shaped pin header or a 3-PIN U-shaped pin header.
[0050] Among them, such as Figures 1 to 2 As shown, the light source board assembly 20 is provided with conductive components 26 at both the bottom and the top. Specifically, the light source board assembly 20 is provided with one conductive component 26 at the bottom and two conductive components 26 at the top. The conductive component 26 is a single-PIN U-shaped pin header.
[0051] like Figures 3 to 4 As shown, a conductive component 26 is provided at the bottom of the light source board assembly 20, and the conductive component 26 is a 3PIN U-shaped pin header.
[0052] In this embodiment, the use of a pin header design for the conductive components can reduce wiring difficulty, simplify circuit design, and provide a stable connection, preventing loosening or instability caused by vibration during vehicle operation. At the same time, due to its smaller size, the internal structure of the automotive lamp can be made more compact, resulting in a smaller overall size.
[0053] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the light source substrate 21 may be an aluminum substrate, a ceramic substrate or a copper substrate. In this embodiment, the light source substrate 21 is preferably a copper substrate.
[0054] In this embodiment, the copper substrate has excellent thermal conductivity, which can effectively dissipate the heat generated by the automotive lamp. At the same time, the copper substrate has the characteristics of corrosion resistance and high strength, making the automotive lamp suitable for various environments.
[0055] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the headlight housing 10 includes a first housing 11 and a second housing 12, which are fastened together by fasteners 13. Both the first housing 11 and the second housing 12 are provided with at least one threaded hole 14 for connection of the fasteners 13. The fasteners 13 are machine screws. Both the first housing 11 and the second housing 12 are also provided with windows 15 for emitting light emitted by the light source unit 23.
[0056] The threaded holes 14 on the first housing 11 and the second housing 12 are positioned correspondingly. The light source substrate 21 is also provided with mounting holes 25 corresponding to the number and position of the threaded holes 14, so that the fastener 13 can pass through the light source substrate 21 and securely install the light source substrate 21 into the vehicle lamp housing 10.
[0057] In this embodiment, the design of the fasteners ensures the overall structural stability of the car light and prevents the internal structure from loosening or being damaged due to vibration during vehicle operation. The tightly structured car light also helps to improve its waterproof and dustproof performance and prevents the internal light source board components from being oxidized and burned out.
[0058] The working principle of this embodiment is as follows:
[0059] The present invention proposes an automotive lamp in which the pins 31 on the power plug 30 are electrically connected to the interface on the light source substrate 21, so that the power plug 30 and the light source substrate 21 can be electrically connected together, realizing that the power plug 30 and the light source board assembly 20 are an optoelectronic integrated structure, thereby reducing the number of external connections and interfaces, simplifying the circuit connection, and making the assembly process of the automotive lamp simpler.
[0060] Second embodiment:
[0061] Please refer to Figures 5 to 8 As shown, unlike the first embodiment, the power plug 30 has three pins 31 and three conductive tabs 32, which are evenly distributed on the power plug 30.
[0062] In this embodiment, the power plug 30 is more suitable for high-power circuit systems than the power plug 20 in the first embodiment. In order to ensure that a stable current or stable voltage is provided in high-power systems, a rectifier board assembly 40 is provided between the light source board assembly 20 and the power plug 30. The rectifier board assembly 40 is provided with a pin hole 41 so that the pin 31 can be plugged into the rectifier board assembly 40 for conduction. The rectifier board assembly 40 and the light source board assembly 20 are electrically connected through a terminal 42.
[0063] Specifically, the number of pin holes 41 is equal to the number of pins 31, and one end of the light source substrate 21 is electrically connected to the rectifier board assembly 40 through a terminal 42, which is soldered onto the rectifier board assembly 40.
[0064] In this embodiment, the rectifier board assembly contains a voltage regulator circuit, which can ensure a stable output voltage or current and avoid performance degradation or damage to the automotive lights due to fluctuations in input voltage or input current. At the same time, the rectifier board assembly has overvoltage and overcurrent protection, short circuit protection and temperature protection. When a fault occurs in the circuit system, it can automatically cut off the power supply to prevent the automotive lights from burning out.
[0065] In addition, such as Figures 5 to 6 As shown, a conductive component 26 is provided at the bottom of the light source board assembly 20. The conductive component 26 is a 3PIN U-shaped pin header. The light source substrate 21 has 6 interfaces 24 on the side near the power plug 30.
[0066] like Figures 7 to 8 As shown, a conductive component 26 is provided at the bottom of the light source board assembly 20. The conductive component 26 is a single-pin U-shaped pin header. Two interfaces 24 are provided on the side of the light source substrate 21 near the power plug 30.
[0067] Third embodiment:
[0068] Please refer to Figures 9 to 10 As shown, unlike the first embodiment, the power plug 30 has one pin and a conductive insert 32.
[0069] In addition, the top of the light source board assembly 20 is provided with two conductive components 26, the conductive components 26 are single-PIN U-shaped pins, the light source substrate 21 is provided with one interface 24 on the side near the power plug 30, and the light source substrate 21 is provided with four interfaces 24 on the side away from the power plug 30.
