Abstract
Description
[0001] The present invention relates to a headlight for a vehicle, comprising at least one light source for generating light rays and at least one covering device that shields a portion of the light rays emitted directly and / or indirectly by the light source. The invention further relates to a vehicle with at least one such headlight.
[0002] Avoiding light in unwanted areas is a constant challenge in the development of vehicle headlights. Usually, the light-guiding component is hidden as far back as possible and then shielded with other components to ensure that light is directed only where it is actually intended.
[0003] From DE 20 2004 001 269 U1 a headlight with a light source and a light cover for shielding radiation emitted by the light source is known.
[0004] Hard components always vibrate inside the headlight. When these parts touch other components, abrasion causes dirt to enter the headlight. Therefore, a gap must always be maintained between the components and the headlight. However, this also means that the light is not completely blocked, as some light can still penetrate through gaps.
[0005] To circumvent this disadvantage, DE 10 2016 102 809 A1 discloses a headlight for a motor vehicle comprising a housing, a light module arranged in the housing, and an elastic cover element. The cover element surrounds the light module and covers an area located between the light module and the housing, the cover element being designed to emit light.
[0006] Furthermore, DE 10 2012 108 774 A1 discloses an arrangement for compensating for gaps between moving parts in a headlight of a motor vehicle, comprising a movable photometric element arranged inside the headlight, a fixed element arranged inside the headlight, and a variable cover element. The variable cover element is coupled to the movable photometric element and the fixed element of the headlight in such a way that it covers a gap between the movable photometric element and the fixed element of the headlight.
[0007] The present invention is based on the objective of creating a headlight and a vehicle that enable improved shielding of light rays while simultaneously preventing dirt from abrasion.
[0008] To solve the problem, a headlight with the features of claim 1 and a vehicle with the features of claim 8 are proposed.
[0009] Advantageous designs of the headlight are the subject of the dependent claims.
[0010] According to a first aspect of the invention, a headlight for a vehicle is proposed. The headlight comprises at least one light source for generating light rays and at least one covering device that shields a portion of the light rays emitted directly and / or indirectly by the light source, wherein the covering device has a contact element made of a soft component that rests against a component of the headlight to shield the light rays.
[0011] Since the cover has a soft component that rests against a part of the headlight, it prevents light rays from escaping through a gap between the component and the cover. Furthermore, the soft component prevents abrasion caused by vibration, which could lead to contamination inside the headlight. Thus, the headlight offers improved light shielding and prevents dirt from accumulating during vibrations.
[0012] In the context of the invention, "contact" means that the soft components make contact with the headlight component, but are not connected to it.
[0013] The light source can contain one or more light-emitting diodes (LEDs) and / or laser diodes. LEDs and / or laser diodes offer high brightness combined with low energy consumption, thus ensuring high energy efficiency.
[0014] In an advantageous embodiment, the headlight has a housing in which the light source is arranged. To protect the light source, the housing is sealed by a lens.
[0015] In an advantageous embodiment, a spring element is provided that presses the cover against the headlight component. The spring element ensures that the soft component always bears sufficient pressure against the headlight component. This effectively prevents the formation of a gap through which light rays could pass.
[0016] In an advantageous embodiment, the spring element is designed as a foam element. A spring element designed as a foam element is cost-effective. The foam element exerts a force on the covering device so that the soft component is pressed against the headlight component and thus remains in permanent contact with it.
[0017] In an advantageous embodiment, the foam element is designed as a foam block, in particular as a cuboid-shaped foam block.
[0018] In an advantageous embodiment, the covering device comprises a support part, wherein the contact element is arranged at a first end of the support part, and wherein the spring element rests against the second end of the support part. Thus, the covering device is a combination component comprising a support part and the soft component for contact with the component. Advantageously, the support part is formed from a rigid component, for example, a plastic, in particular a fiber-reinforced plastic. Advantageously, the support part and the soft component are bonded together by a material interlock.
[0019] Advantageously, the support element has a straight section, a connecting section at the first end for attaching the mounting element, and a mounting section at the second end for attaching the spring element, which projects at an angle from the straight section. Furthermore, the connecting section advantageously has a thinner profile compared to the straight section. The connecting section also advantageously features a flat recess to which the mounting element is attached, particularly by a material bond.
[0020] In an advantageous embodiment, the soft component is injection-molded onto the carrier part. This creates a combination component in a simple and cost-effective manner. Furthermore, the covering device is advantageously manufactured using a two-component injection molding process.
[0021] In an advantageous embodiment, the soft component is made of silicone. A silicone soft component ensures sufficient sealing of any gap between the support component and the headlight component. Furthermore, a silicone soft component is elastic, allowing it to accommodate the relative movements between the support component and the headlight component that occur during vibrations. This effectively prevents light rays from escaping through any gap.
[0022] In an advantageous embodiment, the component is a light disk. Thus, the soft component rests against the light disk to cover a gap between the support part and the light component.
[0023] According to another aspect of the invention, a vehicle is proposed which has at least one headlight according to the invention.
[0024] The following section explains a vehicle, a headlight, and other features and advantages in more detail using an exemplary embodiment, which is schematically depicted in the figures. This shows: Fig. 1 a vehicle with a headlight; Fig. 2. An enlarged representation of the headlight with a lens and a cover; and Fig. 3 a cross-section through the lens and the cover device along a line III-III in Fig. 2.
[0025] In Fig. 1 shows a vehicle 10, which has at least one in Fig. The vehicle 10 has two enlarged headlights 12. It has a drive motor designed as an internal combustion engine and / or an electric motor.
[0026] The in Fig. The headlight 12 shown has a housing 14, a light source 16 arranged inside the housing 14 for generating light rays and a light disc 18 closing off the housing 14 to the outside.
[0027] To shield a portion of the light rays emitted directly and / or indirectly by the light source 16, the headlight 12 has a covering device 20, which is located in the Fig. 2 and Fig. 3 is shown.
[0028] The cover device 20 has a support part 22 and a contact element 26 arranged at a first end 24 of the support part 22. A spring element 30 rests against a second end 28 of the support part 22, pressing the contact element 26 against the lens 26.
[0029] The support element 22 is a planar element made of a plastic, for example, a thermoplastic. The support element 22 has a straight section 32, a connecting section 34 located at the first end 24 for attaching the contact element 26, and a contact section 36 located at the second end 28 for contacting the spring element 30, which projects at an angle from the straight section 32. The connecting section 34 has a smaller thickness compared to the straight section 32 and thus forms a planar recess 38.
[0030] The component 26 is a soft component 40 made of silicone and is metallurgically bonded to the carrier part 22, in particular by injection molding onto the connection section 34. The carrier part 22 is therefore a composite component consisting of the carrier part 22 and the soft component 40. For example, the cover device 20 can be manufactured using a two-component injection molding process.
[0031] The silicone-based soft component 40 rests against the light disc 18 and thus prevents a gap 42 from being exposed during relative movement between the support part 22 and the light disc 18 due to vibrations. For this purpose, the soft component 40 has a sealing lip 46 projecting from a flat base section 44 of the soft component 40, which rests against the light disc 18.
[0032] The spring element 30 is designed as a foam element 48, which in this case is a cuboid-shaped foam block. The foam element 48 is positioned with a preload between the contact section 36 of the support part 22 and a part 50 of the headlight 12 and presses the soft component 40, in particular the sealing lip 46, against the lens 18. As a result, the soft component 40, in particular the sealing lip 46, is permanently in contact with the lens 18 and prevents light rays from escaping through a gap between the lens 18 and the support part 22.
[0033] The headlight 12 according to the invention is characterized by the covering device 20 with a contact element 26 formed from a soft component 40 and the spring element that presses the soft component 40 against the lens 18. This ensures that the soft component 40 is permanently in contact with the lens 18, effectively preventing light rays or light from escaping through a gap between the lens 18 and the support part 26. Furthermore, the soft component 40 prevents abrasion caused by vibration, which would lead to contamination in the headlight 12. Thus, the headlight 12 according to the invention has improved light shielding and simultaneously prevents the formation of dirt.
