[0002] Two major problems exist in the practical application of the existing automobile LED car light: firstly, the anti-vibration effect is poor, and the vibration during vehicle driving easily leads to internal component loosening or damage; secondly, in a humid environment (such as rainy days, high humidity areas), the car light sealing structure is easy to enter water, and the glass surface is easy to condense fog, which seriously affects the illumination brightness and driving safety. Although the traditional halogen bulb lens can alleviate the fog by heating, it has problems such as high energy consumption and short service life, and the existing LED fog lamp is not optimized for anti-vibration and moisture resistance, and cannot meet the reliable use requirements in complex environments. INVENTION CONTENTS

[0010] The LED lamp bead also includes an optional yellow LED lamp bead, which is used for prolonging the irradiation distance.

[0011] The mounting seat and the fixing seat are connected through a damping structure.

[0012] The heat dissipation block is made of metal material and is used for conducting heat generated by the LED lamp bead during work.

DETAILED DESCRIPTION

[0022] The present application will be further described below in combination with the drawings and specific embodiments.

[0023] As shown in the drawings, Figure 1 — Figure 3 an anti-shock waterproof automobile LED car lamp is disclosed.

[0024] Example 1 (basic fog lamp mode): when installed, the heat sink 10 is fixed to one end of the mounting seat 7 (attached to the vehicle body mounting position), and the fixed seat 2 is connected to the other end of the mounting seat; the electromagnetic valve 3, the straight light lamp shade 11, the reflector cup 4, the spotlight PCB circuit board 6 and the lens 1 are installed on the fixed seat in turn. The spotlight PCB circuit board is installed with conventional LED beads (high / low beam lamp plate LED 8), and the waterproof air permeable film 9 at the air outlet hole is a one-way air permeable structure. When the vehicle starts the fog lamp power supply, the high / low beam lamp plate LED 8 is powered on and emits light, the light is reflected to the lens 1 through the reflector cup 4, and the lens is refracted to form a uniform fog lamp illumination beam. At this time, if the environment is humid, a small amount of water vapor generated inside is discharged outward through the waterproof air permeable film 9 at the air outlet hole 71, and external moisture cannot penetrate in the opposite direction, avoiding glass surface fogging.

[0025] Example 2 (high beam illumination mode): when the fog lamp switch is turned again, in addition to the high / low beam lamp plate LED 8 being continuously lit, the light cutting piece 31 of the electromagnetic valve 3 is controlled to retract by the electric signal, thereby removing the shielding of part of the light path (the light cutting piece normally shields part of the light to achieve the basic mode), and the released light is further reflected and refracted by the reflector 4 and the lens 1 to form a high beam illumination with a wider illumination range.

[0026] Example 3 (straight auxiliary illumination mode): when the fog lamp high beam is lit, the straight lamp plate LED 5 (installed on the spotlight PCB circuit board) is started synchronously, and its light is focused through two small lenses on the lens 1, concentrating and enhancing the brightness of the center area of the vehicle lamp (the center point brightness is more than 5 times that of a halogen bulb). If the yellow LED bead version is selected, the light transmittance is stronger, and the illumination distance can be further extended in rainy days.

[0027] Anti-vibration design details: the mounting seat 7 and the fixed seat 2 are integrally formed of metal, and a shock absorbing structure (such as a rubber gasket) is provided at the connection; the heat sink 10 is fastened to the mounting seat by screws, which not only conducts heat but also disperses the impact force of the shock, ensuring that the internal components (such as LED beads and PCB circuit boards) remain stable in bumpy road conditions.

[0028] Technical innovation points:

[0029] 1. LED high-power beads are used, which are brighter, longer-lasting and more comfortable for human vision than traditional halogen bulbs;

[0030] 2. Straight illumination function is added, with center point brightness more than 5 times that of a halogen bulb (2 times higher than similar LED fog lamps on the market);

[0031] 3. Yellow LED bead version can be selected to extend the illumination distance and maintain clear illumination in rainy days;

[0032] 4. The air outlet hole 71 is provided with a waterproof air permeable film 9 (one-way film) to solve the glass fogging problem in humid environments and ensure the light transmittance.

[0033] The technical scheme is adopted,

[0034] 1. Anti-vibration structure: through the stable connection of the mounting seat and the fixing seat and the vibration buffering of the heat dissipation block, the reliability of the vehicle lamp is improved;

[0035] 2. The waterproof and breathable film and the overall sealing design effectively prevent water from entering and fogging; the multi-mode lighting (basic / high beam / direct auxiliary) and the high brightness characteristics significantly enhance the driving safety.
