Description

Technical Field

[0001] This utility model relates to the field of automotive headlight technology, specifically to an anti-glare LED automotive headlight. Background Technology

[0002] Car headlights, also known as car headlights or car LED daytime running lights, are the eyes of a car. They not only affect the appearance of a car owner, but are also closely related to safe driving at night or in bad weather conditions.

[0003] However, in the existing technology, when a vehicle is driving at night, the driver using headlights often makes it impossible for drivers of oncoming vehicles to see the road ahead, causing glare. Glare refers to excessively high brightness in a certain area of ​​the field of vision or excessive changes in brightness. Glare is one of the important causes of visual fatigue. The strong light from oncoming cars at night is an important factor causing glare, which can lead to temporary eye glare and thus greatly increase the risk of traffic accidents, resulting in personal injury to the driver. Utility Model Content

[0004] The purpose of this invention is to provide an anti-glare LED car headlight to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-glare LED automotive headlight, comprising a lamp housing and a lamp cover, wherein a power connector is fixedly installed on one side of the lamp housing, a mounting base is fixedly installed on one side of the power connector, an LED light is installed inside the mounting base, a light guide seat one is fixedly installed inside the lamp housing, a light guide seat two is fixedly installed inside the lamp housing, a baffle plate is fixedly installed on the top of the lamp housing on the side away from the power connector, a focusing convex lens is fixedly installed at the center of one side of the lamp cover, and a diffusing concave lens is fixedly installed on the side of the lamp cover on which the focusing convex lens is fixedly installed.

[0006] Preferably, the side of the lampshade with the baffle plate is snapped onto the outer side of the lamp housing away from the power base.

[0007] Preferably, the convex focusing lens is located inside the concave astigmatic lens.

[0008] Preferably, a focusing cover is fixedly installed inside the lamp housing, and the focusing cover is located outside the LED lamp.

[0009] Preferably, a heat-conducting and heat-dissipating ring is fixedly installed on the outer side of the focusing cover, and the end of the heat-conducting and heat-dissipating ring away from the focusing cover extends to the outer side of the lamp housing, and the interior of the heat-conducting and heat-dissipating ring is filled with coolant.

[0010] Preferably, a rotating seat is rotatably mounted on the side of the power connector away from the lamp housing, and two power connector holes are symmetrically fixedly installed inside the rotating seat. A threaded groove is provided on the outer side of the power connector.

[0011] Compared with the prior art, the beneficial effects of this utility model are: through the combined action of light guide seat one, light guide seat two, convex lens, concave lens and shielding plate, the light emitted by the LED lamp can achieve a lighting effect that is both near and far while maintaining high brightness, and avoids the occurrence of glare to the greatest extent.

[0012] Light guide base one and light guide base two guide the light emitted by the LED light obliquely downwards. Then the light will pass through the convex lens and the concave lens. The light passing through the convex lens will be converged by the convex lens. This convergence process not only enhances the intensity and directionality of the light, allowing the light to illuminate farther places, but also significantly reduces the scattering of light. Even at a long distance, the light can remain clear and bright, ensuring that the driver can see clearly in the distance without being dazzled by scattering.

[0013] The design of the astigmatic concave lens allows light to penetrate and illuminate nearby objects at a wider angle, creating a larger illumination area. This diffusion effect not only ensures that nearby objects are adequately illuminated, facilitating vehicle driving, but also further avoids glare due to the relatively low illumination area. In addition, the baffle plate can guide and block some of the light from the top, ensuring that light only passes through the bottom areas of the focusing convex lens and the astigmatic concave lens, preventing glare caused by the upper part of the astigmatic concave lens scattering the light. This makes the light distribution of the entire lighting system more reasonable and uniform. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution: an anti-glare LED car headlight, including a lamp housing 1 and a lamp cover 2. A power connector 3 is fixedly installed on one side of the lamp housing 1. The lamp cover 2 is snapped onto the outer side of the lamp housing 1 away from the power connector 3 on the side where a baffle plate 13 is installed. A mounting base 8 is fixedly installed on one side of the power connector 3. An LED lamp 9 is installed inside the mounting base 8. A light guide seat 10 and a light guide seat 2 15 are fixedly installed inside the lamp housing 1. A baffle plate 13 is fixedly installed on the top of the lamp housing 1 away from the power connector 3. A focusing convex lens 12 is fixedly installed at the center of one side of the lamp cover 2. A diffusing concave lens 11 is fixedly installed on the side of the lamp cover 2 where the focusing convex lens 12 is fixedly installed. The focusing convex lens 12 is located inside the diffusing concave lens 11. A rotating base 5 is rotatably installed on the side of the power connector 3 away from the lamp housing 1. Two power connector holes 6 are symmetrically fixedly installed inside the rotating base 5. A threaded groove 4 is provided on the outer side of the power connector 3.

[0021] The working principle of the above technical solution is as follows: First, the device is connected to the vehicle body through the power connector 3 and the threaded groove 4, and the LED light 9 is powered through the power connector 6 and the mounting base 8. When the LED light 9 is lit, the light is first guided by the light guide seat 10 and the light guide seat 2 15. The light guide seat 10 and the light guide seat 2 15 guide the light emitted by the LED light 9 obliquely downward. Then, the light passes through the convex lens 12 and the concave lens 11. The light passing through the convex lens 12 is focused by the convex lens 12. This focusing process not only enhances the intensity and directionality of the light, allowing the light to illuminate farther places, but also significantly reduces the scattering of light. Even at a long distance, the light remains clear and bright, ensuring that the driver can see clearly into the distance without being dazzled by scattering. The light passing through the concave lens 11 is diffused by the concave lens 11. The design of lens 11 allows light to penetrate and illuminate nearby objects at a wider angle, forming a larger illumination area. This diffusion effect not only ensures that nearby objects are adequately illuminated, facilitating vehicle driving, but also further avoids glare due to the relatively low illumination area. In addition, the baffle 13 guides and blocks some of the light from the top, ensuring that light only passes through the bottom areas of the convex lens 12 and the concave lens 11, preventing glare caused by the upper part of the concave lens 11 scattering the light. This makes the light distribution of the entire lighting system more reasonable and uniform. Through the combined action of light guide seat 10, light guide seat 15, convex lens 12, concave lens 11, and baffle 13, the light emitted by LED lamp 9 maintains high brightness while achieving a lighting effect that covers both near and far distances, and minimizes glare.

[0022] In another implementation scheme, such as Figures 1-4 As shown, a focusing cover 14 is fixedly installed inside the lamp housing 1, and the focusing cover 14 is located outside the LED lamp 9.

[0023] The light-concentrating cover 14 can reflect and focus the light emitted by the LED lamp 9, thereby improving the light utilization rate.

[0024] In another implementation scheme, such as Figures 1-4 As shown, a heat-conducting and heat-dissipating ring 7 is fixedly installed on the outer side of the focusing cover 14. The end of the heat-conducting and heat-dissipating ring 7 away from the focusing cover 14 extends to the outer side of the lamp housing 1, and the interior of the heat-conducting and heat-dissipating ring 7 is filled with coolant.

[0025] The heat-conducting and heat-dissipating ring 7 and the internal coolant can cool the device during use, thus extending its service life.

[0026] Working Principle: First, the device is connected to the vehicle body via the power connector 3 and threaded groove 4, and the LED light 9 is powered through the power connector 6 and mounting base 8. When the LED light 9 is lit, the light emitted by the LED light 9 is reflected and focused by the condenser 14, improving light utilization. The light is first guided by the light guide seat 10 and the light guide seat 2 15, which guide the light emitted by the LED light 9 obliquely downwards. Then, the light passes through the convex lens 12 and the concave lens 11. The light passing through the convex lens 12 is focused by the convex lens 12. This focusing process not only enhances the intensity and directionality of the light, allowing the light to illuminate farther places, but also significantly reduces light scattering. Even at a greater distance, the light remains clear and bright, ensuring that the driver can see clearly into the distance without being dazzled by scattering. The light passing through the concave lens 11 is diffused by the concave lens 11. The design of the concave lens 11... This allows light to penetrate and illuminate nearby objects at a wider angle, creating a larger illumination area. This diffusion effect not only ensures sufficient illumination for nearby objects, facilitating vehicle driving, but also further prevents glare due to the relatively low illumination area. Additionally, the baffle 13 guides and blocks some of the light from the top, ensuring that light only passes through the bottom areas of the convex lens 12 and the concave lens 11, preventing glare from the upper part of the concave lens 11. This results in a more reasonable and uniform light distribution throughout the lighting system. Through the combined action of the light guide seat 10, light guide seat 15, convex lens 12, concave lens 11, and baffle 13, the light emitted by the LED lamp 9 maintains high brightness while achieving illumination effects that cater to both near and far objects, and minimizes glare. The heat dissipation ring 7 and internal coolant help to cool the device during use, extending its lifespan.
