Description

Lighting device for vehicle

It is pressed according to claim 1 lighting device and one kind as described in the preamble for vehicle the present invention relates to a kind of According to the motor vehicle with lighting device described in claim 10 preamble.

For the lighting device of modern vehicle, constantly there are more lighting functions to be integrated in a lighting device. This, can not possibly to the same extent increase the structure space provided to lighting device in vehicular field just.The result is that Function carrier on small space placement technique.

If lighting device for example comprising for dipped headlight and high beam and for the function carrier of daytime running lamps, leads to Different illuminating devices is often used as light source.These light sources send out the light designed for various lighting functions.It to avoid herein , these lighting functions influence each other, this can for example cause the optical quality of vehicle to reduce.This influence can for example be leaked in light Occur when into some regions, should not actually occur corresponding lighting function in this region.Even if working as single lighting function It runs separated from each other, the undesirable leakage of light can also make the impression optically of vehicle be deteriorated.If available structure space quilt Strong limitation, then just produce special requirement when designing this lighting device.

10 2,013 104 176A1 of document DE for example illustrate a kind of lighting device for vehicle, lighting device tool There is different light sources, wherein with baffled between light source and optical conductor, by baffle so that light is only capable of the circumferential surface in optical conductor Back side on inject.

In addition, 199 43 255A1 of document DE disclose a kind of lighting unit for motor vehicle, with optical conductor, Light can be injected in optical conductor with coupling element.Light arranges in the housing that shell is covered with covering original paper with coupling element.Covering Recessed portion is arranged in original paper region-type, and optical conductor is supported in recessed portion.

The technical problem to be solved by the present invention is to provide a kind of lighting device for vehicle, light can pass through the illumination Device injects optical conductor, and here, even when the different elements of lighting device to arrange relative to each other compared with high tolerance, and light is not yet Leak into the environmental system of lighting device.

Other preferred designs of the present invention are by other, the feature obtains in the dependent claims.

Lighting device for vehicle comprising at least one illumination component for generating light and at least one have The optical conductor of at least one incident area for light, the luminous energy are generated by illumination component, the lighting device further include to A few baffle.According to present invention provide that, baffle is at least partially the characteristic of the elasticity of shape and/or softness and at least portion Section ground extends along optical conductor and illumination component, with Special composition region, illumination component and incident area both facing to the area of space, And light hermetically sticks on optical conductor baffle at least in a region.

What term " elasticity of shape " and " softness " were known to those skilled in the art.Difference lies in shapes for the two The object of elasticity is resiliently deformed by power and reverts to its original-shape after power cancellation.By contrast, soft object Since the effect of power deforms, and its original-shape is not restored when power disappears.Soft object is especially merely due to act on it Gravity just deform.The object of the elasticity of shape is, for example, rubber slab.Soft object is, for example, the cotton fabric of plane.This field Technical staff is it is known that there is also the mixed forms of the elasticity of shape and flexibility.Thus, for example assigning rubber by reducing plate thickness A part of flexibility of characteristic of plate.

Correspondingly, the characteristic of the baffle of lighting device according to the invention can especially be kept off by selecting material and by determining The structure of plate is affected.Baffle both can be with integral type, can also multi-piece type.Baffle can also be composite component.For example, baffle by Polymer material is constituted.This material for example can be silicones or ethylene propylene diene rubber.By selecting material thickness can be with Influence characteristic of the baffle in terms of the elasticity of shape or flexibility.As composite component, baffle can also for example have metal core, The metal core is surrounded by polymer material.In this case, the characteristic of the elasticity of shape is for example ensured by metal core.Baffle can also It is made of other materials, such as by the material with fiber, which is processed to fabric.This fabric is knitted such It is close so that it is lighttight.In conjunction with the present invention, the opaque leakage for meaning light at least can no longer be felt by people.If with Measuring device inspection, then related technical personnel automatically define corresponding boundary value.Material with fiber can be aramid fiber, cotton Or the known material with fiber of other skilled in the art.This baffle can especially have soft characteristic. In the region that baffle light hermetically reclines on optical conductor, the different mechanism of action can be realized accordingly.For example, baffle can be by It is hermetically sticked on optical conductor in its elasticity of shape light.If there is soft baffle, can using auxiliary material or Light is hermetically laid on optical conductor or is arranged to stick on optical conductor in the case of person's additional component.Here, viscous It is only pure citing to connect.Required adaptation is independently carried out by those skilled in the art under this technology introduction.

According to the present invention, illumination component had both included at least one for luminous illuminating device, also including other for hair Technical pattern needed for light.Holding structure for example including machinery and the possible design scheme that the energy is provided thus.

Term " baffle extends along optical conductor and illumination component " not mandatory expression baffle must also stick on these yuan It is connected on part or with these elements.It is opposite to refer to baffle substantially along the profile phase with each element (optical conductor, illumination component) Same direction extends or extends past at the profile.It is only that baffle is at least one area according to what the present invention limited Light hermetically sticks on optical conductor.
