Description

[0001] This application is a divisional application of application No. 201711239838.6 entitled "Vehicle lamp including a light-emitting portion having an opalescent effect", filed with the State Intellectual Property Office on November 30, 2017. Technical Field

[0002] This invention relates to vehicle lights including a light-emitting portion having a milky sheen. Background Technology

[0003] The term "vehicle lights" is often used indiscriminately to refer to either taillights or headlights, the latter also known as headlights or front lights.

[0004] As is known, vehicle lights are lighting and / or signaling devices for a vehicle, including at least one light on the exterior of the vehicle that has the function of illuminating and / or signaling from the vehicle toward the outside, such as position lights, turn signals, brake lights, rear fog lights, reversing lights, low beam headlights, high beam headlights, etc.

[0005] Automotive lights, in their simplest form, consist of a container body, a lens body, and at least one light source.

[0006] The lens is positioned to enclose the opening of the container body to form a receiving chamber. A light source is arranged in the receiving chamber and is rotatable so that it emits light toward the lens when energized.

[0007] After assembling the various components, the construction of the headlight involves fixing the lens body and sealing it hermetically to the container body. Summary of the Invention

[0008] There is a growing sense within the field that vehicle lights are needed not only as a means of obtaining beams that meet standard requirements and specific light intensity requirements, but also as a specific design means for vehicles on which lights are applied.

[0009] Therefore, the light patterns emitted by lamps not only serve the function of signaling and / or illuminating, but also create the precise lighting effects required. These lighting effects or patterns increasingly represent the main theme for some automakers, and together with the lamp's optics, they are intended to differentiate themselves from their competitors.

[0010] However, this lighting effect should not compromise the uniformity of the produced beam. While beam uniformity is not related to specific luminous intensity requirements, it is considered necessary by the end user. In other words, a non-uniform beam, although meeting the lamp's luminous intensity requirements, may be considered an unacceptable "defect" by the end user of the vehicle headlights.

[0011] Various methods for ensuring uniformity are known, such as introducing lenses or filters with an opalescent effect.

[0012] Various methods exist in the art for achieving an opalescent effect on automotive headlights. The most popular method is to use opalescent materials, which produce an opalescent lighting effect when illuminated by a beam of light.

[0013] The opalescent material is made of a polymeric material incorporating microspheres made of different materials to allow light to be randomly dispersed.

[0014] It is possible to achieve an opalescent effect through this random diffusion of the light beam.

[0015] However, there are regulations, such as those in the United States, that prohibit the use of this material in the automotive lighting industry.

[0016] Therefore, it has been recognized in the art that there is a need for a vehicle lamp that can simultaneously produce a uniform beam with an opalescent effect without using any opalescent materials.

[0017] This requirement is met by the vehicle lights according to claim 1.

[0018] Other embodiments of the invention are described in the dependent claims. Attached Figure Description

[0031] Common elements or portions of elements in the embodiments described below will be indicated by the same reference numerals. Detailed Implementation

[0032] Referring to the aforementioned accompanying drawings, denoted as Figure 4, which generally indicates the vehicle lights, the following discussion will refer to these lights without losing their generality.

[0033] As mentioned above, the term "vehicle lights" is often used indiscriminately to refer to either taillights or headlights, the latter also known as headlights or front lights.

[0034] As is known, vehicle lights include at least one light on the exterior of a vehicle that has illumination and / or signaling functions, such as position lights (which may be front position lights, rear position lights, side position lights), turn signals, brake lights, rear fog lights, reversing lights, low beam headlights, high beam headlights, etc.

[0035] The headlight 4 includes a container body 8, which is typically made of a polymer material that usually allows the headlight 4 to be attached to the relevant vehicle.

[0036] For the purposes of this invention, the container body 8 may have any shape, size and location: for example, the container body 8 may not be directly associated with the body of the relevant vehicle or other accessories.

[0037] According to one embodiment, the container body 8 defines a receiving seat 12 that houses at least one light source 16, said light source 16 being adapted to emit multiple light rays Ri when energized, the multiple light rays Ri defining a beam of light that will propagate outside the vehicle headlight 4. For the purposes of this invention, the type of light source used is irrelevant; preferably, the light source 16 is a light-emitting diode (LED) light source.

[0038] The receiving body 8 can accommodate the intermediate support element 18 of various optical and / or electronic components of the vehicle lamp 4 in the receiving seat 12 in a known manner.

[0039] For example, the light source 16 is supported and powered by a suitable base 19 in a known manner.

[0040] The headlight 4 also includes a lens 20, which is at least partially adjacent to the container body 8.

[0041] The lens body 20 is applied to the container body 8 so as to at least partially close the housing 12 that houses at least one main light source 16.

[0042] For the purposes of this invention, the lens body 20 may be external so as to define at least one outer wall of the vehicle lamp that is directly affected by the external environment.

[0043] It is also possible to provide the lens body 20 inside the vehicle so that it can be housed within the vehicle interior; this is the case, for example, with a roof light or a light that is part of the vehicle's dashboard.

[0044] The lens body 20 encloses the receiving seat 12 and is adapted to allow the light generated by the main light source 16 to pass through.

[0045] In this respect, the lens body 20 is made of at least partially transparent or translucent or semi-transparent material, and may also include one or more opaque portions, but still allows at least a portion of the main beam emitted by the at least one main light source 16 to pass through.

[0046] According to possible embodiments, the lens body 20 is made of resin, such as PMMA, PC, etc.

[0047] The headlight 4 also includes a diffuser body 24, which is defined by its light input wall 28 and its light output wall 32.

[0048] The diffuser body 24 faces the at least one light source 16 so that its beam can pass through it.

[0049] The light output wall 32 may face the lens body 20 directly and / or indirectly; "directly" means that the light output wall 32 is at least partially located in front of the lens body 20; "indirectly" means that the light output wall 32 is not located in front of the lens body 20, but can guide the light beam emitted from it onto the lens body 20, for example, through an inserted reflective surface.

[0050] The diffuser body 24 extends along the main lateral extension direction TT, which is preferably perpendicular to the main propagation direction LL of the beam.

[0051] Advantageously, the diffuser body 24 has a first set 48 first optical elements 52, which are defined as cylindrical optical devices with a circular cross-section suitable for forming cylindrical caustics or spherical optical devices suitable for forming spherical caustics. The first optical elements 52 scatter the light Ri toward the light output wall 32 through subsequent refraction in order to emit a beam of light with an opalescent effect.

[0052] Advantageously, the first group 48 and the first optical element 52 are solid bodies that are juxtaposed without interruption, for example, at least partially intersecting each other to form a single body.

[0053] Specifically, adjacent first optical elements 52', 52" pass through each other at least partially at the first intersection portion 54, thereby achieving a mechanical connection between the first optical elements that are adjacent to each other.

[0054] Therefore, the first optical element 52 of the first group 48 is separated from the light source 16 and the lens body 20 through the air gap 56.

[0055] According to one embodiment, the first optical element 52 in the first group 48 has a diameter ranging from 1 mm to 5 mm.

[0056] As described above, the first optical elements 52 are substantially tangential to each other or at least partially interpenetrating each other, for example, substantially tangential to each other or at least partially interpenetrating each other in a circular sector 60, wherein the area of ​​the circular sector 60 is equal to 1% to 10% of its total area when measured relative to a cross section perpendicular to the first axis of symmetry XX of the first optical elements 52 (see...). Figure 4 (The magnified detail VI is related to the two adjacent first optical elements 52' and 52").

[0057] It should be noted that the tangency or interpenetration of the first optical element 52 can depend on the manufacturing process: injection molding processes typically involve the interpenetration of the same elements.

[0058] For the operational purposes of this invention, it is important that there is no free path from the first optical element 52 for the light ray Ri; in other words, all light rays Ri must pass through the first optical element 52 to be optically affected by the first optical element.

[0059] According to possible embodiments ( Figures 1 to 5 The first optical element 52 is a cylinder 64 with a circular cross-section, wherein each of its axes of symmetry XX is perpendicular to the main propagation direction LL of the beam, and these cylinders are equidistant from each other and all have the same diameter.

[0060] According to possible further embodiments ( Figures 6 to 10 The first optical element 52 is a sphere 68, which are equidistant from each other and have the same diameter.

[0061] Preferably, the diffuser body 24 has a diffuser portion 72 on the light output wall 32 side, the diffuser portion 72 including micro-optical devices and / or reliefs and / or glazes suitable for equalizing and diffusing the light beam emitted by the light output wall 32.

[0062] In other words, the diffuse portion 72 is used to blur the light until the outline of the first optical element 52 is eliminated to fix the sole contribution provided by the cylindrical or spherical optical device described above.

[0063] Therefore, in order to achieve the opalescent effect, the synergistic effect between the first optical element 52 and the diffuser portion 72 is required.

[0064] In practice, the first optical element 52 scatters the light Ri toward the light output wall 32 through subsequent refraction, and the diffuse portion 72 blurs the light until the outline of the first optical element 52 is eliminated to fix the sole contribution provided by the cylindrical or spherical optical device. In this way, a complete and uniform opalescence effect can be obtained.

[0065] The diffuse portion 72 may also be formed on the lens body 20, and the diffuse portion 72 includes micro-optical devices and / or reliefs and / or enamels suitable for equalizing and diffusing the light beam emitted from the light output wall 32.

[0066] Alternatively, a screen 76 may be provided between the diffuser body 24 and the lens body 20. This screen includes a diffuser portion 72 comprising micro-optical devices and / or embossed and / or enamel materials suitable for equalizing and diffusing the light beam from the light output wall 32. Clearly, this screen is configured to allow the light beam incident upon it to pass through.

[0067] Preferably, the container body 8 accommodates at least two light sources 16', 16'", which are adapted to emit multiple rays Ri', Ri' diffused in the form of light cones C', C'" when energized.

[0068] The aperture β of the light cone defines a light intensity equal to half the intensity emitted by the light source along its optical axis.

[0069] Light sources 16' and 16" are configured and / or spaced apart such that two adjacent light cones C' and C" intersect at least partially on the diffuser body 24. Figure 13 ).

[0070] Preferably, the light cones C' and C” intersect at the light input wall 28 of the diffuser body 24.

[0071] Due to the intersection of the light cones C' and C'" of adjacent light sources, an overall opalescent effect can be achieved.

[0072] According to one embodiment ( Figures 6 to 10 The diffuser body 24 has a second set 80 second optical elements 84, which define a cylindrical optical device suitable for achieving cylindrical caustics or a spherical optical device suitable for achieving spherical caustics. The optical device scatters the light Ri toward the light output wall 32 through subsequent refraction in order to produce a beam with an opalescent effect.

[0073] The second group 80 and the second optical elements 84 are juxtaposed without interruption, for example, at least partially intersecting each other to form a single body.

[0074] Specifically, adjacent second optical elements 84', 84" pass through each other at least partially at the second intersection portion 86, thereby achieving a mechanical connection between the adjacent second optical elements.

[0075] The second optical element 84 is placed between the first optical element 52 and the lens body 20 and is separated from the first optical element 52 and the lens body 20 through an air gap 56.

[0076] Specifically, the second optical element 84 is spaced apart from the first optical element 52 by a spacing 88.

[0077] The spacing 88 between the first group 48 and the second group 80 is at least 1.1 times the diameter of the first optical element 52 and the second optical element 84.

[0078] The spacing 88 represents the distance measured parallel to the main propagation direction LL between the axis of symmetry XX of the first optical element 52 and the axis of symmetry YY of the second optical element 84 that directly faces the first optical element 52.

[0079] According to one embodiment, the second optical element 84 is at least partially staggered relative to the first optical element 52 along a lateral direction TT perpendicular to the main propagation direction LL of the light beam, such that a first intersecting portion 54 between two adjacent first optical elements 52', 52" is staggered relative to a second intersecting portion 86 between two adjacent second optical elements 84', 84" such that the first intersecting portion 54 and the second intersecting portion 86 are offset from each other relative to the main propagation direction LL.

[0080] According to one embodiment, the second optical element 84 in the second group 80 has a diameter ranging from 1 mm to 5 mm.

[0081] For example, the second optical elements 84 are substantially tangent to each other or penetrate each other, for example, substantially tangent to each other or penetrate each other in the circular sector 60, wherein the area of ​​the circular sector 60 is equal to 1% to 10% of its total area when measured relative to a cross section perpendicular to the second axis of symmetry YY of the second optical elements 84.

[0082] For the operational purposes of this invention, it is important that there is no free path for light ray Ri from the first optical element 52 and / or the second optical element 84; in other words, all light ray Ri must pass through the first optical element 52 and / or the second optical element 84 to be optically affected by them. It should be noted that whether the second optical element 84 is tangential or interpenetrating can depend on the manufacturing process: injection molding processes typically employ interpenetration of the same elements.

[0083] Preferably, the second optical element 84 is a circular cross-sectional element that is equidistant from each other and has the same diameter.

[0084] Preferably, the second optical element 84 is the same as the first optical element 52.

[0085] According to one possible embodiment, the second optical element 84 is a cylinder 64 with a circular cross-section, wherein each of its respective axes of symmetry YY is perpendicular to the main propagation direction LL of the beam, and these cylinders are equidistant from each other and all have the same diameter.

[0086] According to another possible embodiment, the second optical element 84 is from spheres 68 that are equidistant from each other and have the same diameter.

[0087] For example, the light output wall 32 is arranged on the second optical element 84, and the diffuser body 24 may have a diffuse portion 72 on the side of the light output wall 32, which includes micro-optical devices and / or reliefs and / or glazes suitable for equalizing and diffusing the light beam from the light output wall 32.

[0088] A screen 76 may also be provided disposed between the diffuser body 24, particularly the second optical element 84 and the lens body 20, wherein the screen includes a diffuser portion 72 comprising micro-optical devices and / or reliefs and / or enamels suitable for equalizing and diffusing the light beam from the light output wall 32. Clearly, the screen is configured to allow the light beam incident upon it to pass through.

[0089] The optical operation of the vehicle lamp according to the invention will now be described to illustrate how the desired optical effect can be achieved by using optical elements (such as diffuser bodies).

[0090] Specifically, Figure 11 This illustrates the behavior of a light beam with a direction parallel to the ray Ri, which is incident on an optical element and undergoes subsequent refraction and reflection according to the two limiting output directions R. i' R i” The angular distribution between them deviates.

[0091] Refraction and reflection occur when the light beam passes from the air in the gap 56 between the light source 16 and the first optical element 52 to the material of the diffuser body 24 of these optical elements, and subsequently from the material of the diffuser body 24 to the air in the gap 56 between the first optical element 52 and the screen 76, or between the first optical element 52 and the second optical element 84 (if provided). In this latter configuration, the light from the gap 56 between the first optical element 52 and the second optical element 84 undergoes a new refraction / reflection process when it is incident on the second optical element 84.

[0092] The light beam is thus diffused by a light cone having an aperture angle 2α, which depends on the device material through which the beam passes. For example, in the case of PMMA or PC as the main body, this angle α is approximately 60 degrees. This light cone has a virtual focal point F located outside the optical element. i The apparent origin within.

[0093] Figure 12 The same optical diffusion pattern is shown under three different beam conditions, each beam having a direction parallel to light rays R1, R2, R3 from different directions within the diffuser body 24 and incident on the same optical element.

[0094] Each of the beams is diffused into a light cone with an aperture angle of 2α, which depends on the device material through which the beam passes. Specifically, each beam having a direction parallel to light rays R1, R2, R3 is incident on the optical element, and due to subsequent refraction and reflection, the beams are diffused according to the two limiting output directions R1, R2, R3, respectively. 1' R 1” R 2' R 2” R3' R 3” The angular distribution between them deviates.

[0095] In addition, each ray R1, R2, R3 determines a 2α brightness light cone within the corresponding virtual focal points F1, F2, F3 inside the optical element.

[0096] The overlap of such light cones Ri', Ri” from different directions enables the acquisition of a light distribution that is essentially ideally scattered (Lambertian) at the output of the optical element, which is almost identical to the volume scattering typically formed by opalescent materials.

[0097] As can be understood from the above, the present invention overcomes the shortcomings of the prior art.

[0098] Specifically, the lamp according to the invention allows for the acquisition of any opalescent light pattern without using any opalescent material layer on the external lens body or the diffuser body of the lamp.

[0099] Specifically, the geometry of the optical elements forms spherical or cylindrical caustics, which utilize the refraction of light passing through different components (i.e., the plastic material of the diffuser body and air). In this way, the incident beam diffuses at an angle depending on the material it passes through and is randomly distributed to diffuse and scatter the light, achieving the opalescent effect as shown.

[0100] The interaction between the first and / or second optical elements and this micro-optical device or relief results in a uniform effect, illuminating the diffuser body with an LED light source. In other words, this is in the state when the headlights are activated.

[0101] Clearly, the lamp of the present invention can meet all the light intensity specifications of a lamp and can emit a uniform beam of light that is pleasing to the observer's eye.

[0102] In summary, the present invention allows for the production of vehicle lights that produce a uniform beam with an opalescent effect without the use of opalescent materials.

[0103] To meet possible and specific requirements, those skilled in the art can make numerous modifications and variations to the above-described vehicle lights, all of which fall within the scope of the invention as defined in the following claims.
