[0022] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Embodiment 1: Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 as shown, the present embodiment provides a reliable LED car lamp, including:

[0024] A lamp body 1, in which a mounting hole 100 is formed, and an LED lighting module 2 is disposed in the mounting hole 100;

[0025] The connector 3 is arranged at the end of the lamp body 1, and a drive control module 4 is arranged in the lamp body 1 and / or the connector 3. The drive control module 4 is electrically connected to the LED lighting module 2;

[0026] The chuck 5 is provided with a plurality of clamping portions 51, and a plurality of through holes 52 are formed in the chuck 5;

[0027] The snap ring 6 is sleeved inside the chuck 5 and outside the lamp body 1. A plurality of snap points 61 are protrudingly arranged on the snap ring 6 for connecting with a carrier, and the snap points 61 are located in the corresponding through holes 52.

[0028] The reliable LED car lamp provided by this embodiment can, to a certain extent, reduce the looseness of the lamp body after installation, thereby ensuring the lighting effect of the LED car lamp.

[0029] Specifically, the chuck 5 of the lamp body 1 is provided with clamping portions 51, and the snap ring 6 is provided with snap points 61 for connecting with the reflector of the LED car lamp. The double connection makes the connection between the lamp body 1 and the reflector of the LED car lamp more stable and reliable, reducing the looseness of the lamp body after installation, thereby ensuring the lighting effect of the LED car lamp. In addition, compared with screw connection, the clamping connection method has higher efficiency, is convenient for production and assembly, and is also convenient for later users to repair and replace.

[0030] In this embodiment, a mounting seat 7 is sleeved outside the chuck 5. A connection hole 53 is formed in the chuck 5, and a bump 71 is arranged on the mounting seat 7. The bump 71 is clamped in the corresponding connection hole 53, and the chuck 5 is fixed to the lamp body 1 through the mounting seat 7. Its structure is simple and the design is reasonable, so as to facilitate the installation and fixation of the chuck 5. At the same time, the connection between the lamp body and the reflector is also facilitated through the arranged mounting seat 7.

[0031] Preferably, an annular waterproof silicone rubber ring 8 is sleeved on the mounting seat 7. Its structure is simple, so as to increase the overall sealing and waterproof performance of the LED car lamp.

[0032] In this embodiment, a heat dissipation structure 101 is arranged on the lamp body 1. The heat dissipation structure 101 includes a plurality of heat dissipation ribs distributed at intervals. Its structure is simple, so as to ensure the heat dissipation ability of the LED car lamp and avoid the influence of high temperature on the working stability of the LED car lamp.

[0033] Further, a driving motor 91 and a cooling fan 92 are arranged in the lamp body 1. The driving motor 91 is electrically connected to the driving control module 4 and the cooling fan 92 respectively. The structure is simple, which can further ensure the heat dissipation capacity of the LED car lamp and avoid the influence of high temperature on the working stability of the LED car lamp.

[0034] In this embodiment, the thickness of the LED lighting module 2 is 1.2 mm - 1.5 mm, which can make the finished product of the LED car lamp thinner and lighter.

[0035] Furthermore, the LED lighting module 2 adopts a double-sided eutectic structure, which includes a substrate and LED chips arranged on the front and back surfaces of the substrate.

[0036] The double-sided eutectic structure is a packaging method for LED chips. Its characteristics are: directly pressing and welding the LED chips onto the circuit board to achieve the electrothermal connection of the chips, breaking through the bottleneck that the traditional thermoelectric separation cannot solve the heat conduction channel. Different from the traditional "flip-chip" packaging, the double-sided eutectic technology can shorten the connection path of the chips, directly eutectic on the circuit, reduce the thermal resistance of the materials, and improve the luminous efficiency. That is, the double-sided packaging structure is: chip - eutectic copper circuit - aluminum nitride substrate (the total thermal resistance is 0.616). The single-sided packaging is: chip - eutectic to aluminum nitride substrate - soldering paste - copper substrate (the total thermal resistance is 2 - 2.5). The junction temperature calculation formula is TJ = the highest temperature of the substrate + power * thermal resistance. The actual junction temperature of the double-sided packaging is much lower than that of the single-sided packaging and then pasting the copper plate (the difference is 20 - 30 °C). The main breakthrough points of this packaging technology include: reducing the electrode connection path and reducing the number of thermal resistance layers of the chips. The packaging process is simple, without wire bonding, and it is easier to realize automated production.

[0037] In addition, the luminous spacing between the double-sided eutectic chips is only 1.2 mm, which is exactly the same as the size of the tungsten filament lamp, bringing incomparable light pattern and illumination intensity. Low thermal resistance and good heat conduction of the aluminum parts will bring higher luminous efficiency, meeting the products compliant with traffic road safety regulations.

[0038] At present, there are very few products in the LED industry that can pass the regulatory tests. It is very difficult for traditional chip modules to meet the regulatory standards with precise control. For example, the control of the soldering tin amount between the lamp beads and the copper plate, the control of the size of the lamp beads and the pads, the coincidence of the sizes of the two-sided chips, the control of the processing accuracy of the aluminum parts, etc. are all quite difficult, while only the accuracy of the aluminum parts needs to be controlled for the double-sided eutectic.

[0039] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
