Description

Vehicle lighting device

[0001] The present invention relates to a vehicle lighting device, such as a vehicle lighting device used for a vehicle such as an automobile.

[0002] Conventionally, an emblem that emits light may be attached to a vehicle. In this case, in existing products, it is generally designed as an emblem lighting device having a dedicated light source. Near the emblem lighting device, other vehicle lighting devices, such as a center lamp, may be arranged, but the emblem lighting device and this vehicle lighting device are designed separately as separate devices. On the other hand, in order to reduce the manufacturing cost as a whole, it has been proposed to integrate the emblem lighting device into the vehicle lighting device (see, for example, Patent Document 1). In this proposal, the vehicle lighting device includes a light source, a light guide body having a rod-shaped light guide portion and a plate-shaped light guide portion connected to the side surface of the rod-shaped light guide portion. Light from the light source enters the end surface of the rod-shaped light guide portion, and the light emitted from the side surface of the rod-shaped light guide body forms the light distribution as a vehicle lighting device. An emblem portion is formed on the plate-shaped light guide portion, and the emblem portion emits light by the light guided from the rod-shaped light guide portion to the plate-shaped light guide portion.

[0004] The inventor has studied a vehicle lighting device having a design portion that emits light, such as an emblem or a logo, and recognized the following problems. Different from the above-described form of the vehicle lighting device, a reflector-type lighting device that reflects light from a light source and uses the reflected light for the emission of the design portion is also conceivable. When configuring a long lighting device that extends long in a predetermined direction, for example, the vehicle width direction, on the vehicle in a reflector type, a large number of light-emitting elements may be arranged in the longitudinal direction of the lighting device, and a reflector may be arranged along these light-emitting elements. The reflector may have a large number of concave reflecting surfaces corresponding to the light-emitting elements. The reflected light from the reflector illuminates the design portion. In a typical design, each light-emitting element may be arranged at the center of the corresponding concave reflecting surface. However, the inventor has recognized that in such a design, the emission of the design portion may become non-uniform in the longitudinal direction, such as being bright near each light-emitting element and dark between the light-emitting elements. The closer the distance between the reflector and the design portion, the more likely such a problem will occur.

[0005] The present invention has been made in view of these circumstances, and one exemplary objective of a certain embodiment thereof is to improve the uniformity of light emission in a light-emitting design portion provided in a vehicle lighting fixture.

[0006] A vehicle lamp according to one aspect of the present invention comprises: a row of light-emitting elements including a plurality of light-emitting elements arranged in a predetermined arrangement direction; a reflector arranged along the row of light-emitting elements, the reflector having a plurality of concave reflective surfaces arranged in the arrangement direction and reflecting light emitted by the plurality of light-emitting elements; and a first inner lens having a three-dimensional design element on its surface and emitting light upon receiving light reflected by the plurality of concave reflective surfaces. The position of each of the plurality of light-emitting elements in the arrangement direction is offset from the center position of each of the plurality of concave reflective surfaces in the arrangement direction.

[0007] A vehicle lamp according to one aspect of the present invention comprises a first inner lens having a three-dimensional design element on its surface, and a second inner lens having a design opening with an opening shape that matches the three-dimensional design element of the first inner lens. The second inner lens is positioned adjacent to the first inner lens such that the three-dimensional design element of the first inner lens is positioned in the design opening.

[0008] According to the present invention, it is possible to improve the uniformity of light emission in a light-emitting design portion provided in a vehicle lighting fixture.

[0009] This is a schematic diagram showing the vehicle lighting fixture according to the embodiment installed on a vehicle. This is a schematic front view showing a part of the vehicle lighting fixture according to the embodiment. This is a schematic cross-sectional view of the vehicle lighting fixture along line A-A shown in Figure 2. This is a schematic perspective view showing an enlarged portion of the design part provided on the vehicle lighting fixture according to the embodiment. This is a schematic front view showing a part of the vehicle lighting fixture according to a comparative example.

[0010] The present invention will be described below with reference to the drawings, based on preferred embodiments. The embodiments are illustrative and not limiting, and not all features or combinations thereof described in the embodiments are necessarily essential to the invention. The same or equivalent components, members, and processes shown in each drawing are denoted by the same reference numerals, and redundant explanations are omitted as appropriate. Furthermore, the scale and shape of each part shown in each drawing are set for convenience to facilitate explanation and are not to be interpreted restrictively unless otherwise specified. In addition, terms such as "first," "second," etc., used in this specification or claims do not indicate any order or importance, but are used to distinguish one configuration from another. Furthermore, some components that are not important for explaining the embodiments are omitted in each drawing.

[0011] Figure 1 is a schematic diagram showing the vehicle light fixture 10 according to the embodiment installed on a vehicle. Figure 2 is a schematic front view showing a part of the vehicle light fixture 10 according to the embodiment. Figure 3 is a schematic cross-sectional view of the vehicle light fixture 10 along the line A-A shown in Figure 2. Figure 4 is a schematic perspective view showing an enlarged portion of the design part 30 provided on the vehicle light fixture 10 according to the embodiment.

[0012] The vehicle light fixture 10 has a long, slender shape that extends along its longitudinal direction (left-right direction in Figures 1 and 2). As shown in Figure 1, the longitudinal direction of the light fixture corresponds to the vehicle width direction when mounted on a vehicle. When mounted on a vehicle, the vehicle light fixture 10 may extend over, for example, at least half, or almost the entire width direction of the vehicle.

[0013] A pair of rear combination lamps 11 may also be mounted on the left and right sides of the rear of the vehicle. The rear combination lamps 11 may consist of multiple lamps that provide different functions from each other (for example, marker light functions), in this example, a tail lamp 11a, a stop lamp 11b, a turn signal lamp 11c, and a backup lamp 11d.

[0014] The vehicle light fixture 10 may be positioned between the two taillights 11a, adjacent to the left taillight 11a at its left end and adjacent to the right taillight 11a at its right end. In this embodiment, the vehicle light fixture 10 is a center lamp positioned in the center of the rear of the vehicle and is configured to function as a taillight. Visually, the vehicle light fixture 10 may extend in the vehicle width direction to connect the two taillights 11a, and together with the two taillights 11a, it may create a horizontal luminous design that extends across the entire rear of the vehicle in the vehicle width direction.

[0015] The design portion 30 of the vehicle light fixture 10 is incorporated into the vehicle light fixture 10 so as to emit light when the vehicle light fixture 10 is turned on. In this example, the design portion 30 is located in the center of the vehicle light fixture 10 in the vehicle width direction. Typically, the design portion 30 may include a symbol mark indicating the vehicle manufacturer or model, such as a logo or emblem. In the illustrated example, the design portion 30 has the string "ABCDE" as an example of a logo. In this embodiment, as will be described later, the design portion 30 is configured to represent a symbol mark such as a logo or emblem in three dimensions.

[0016] As shown in Figure 3, the vehicle light fixture 10 comprises a lamp body 12 and a front cover 14. Both the lamp body 12 and the front cover 14 have an elongated shape that extends in the longitudinal direction of the vehicle light fixture 10. The front cover 14 is combined with the lamp body 12 to form a light chamber 16. The front cover 14 is attached to the lamp body 12 so as to cover the front opening of the lamp body 12. Typically, the lamp body 12 is made of a suitable material, such as a general-purpose resin material.

[0017] In this example, the front cover 14 has an outer lens portion 14a, an upper cover portion 14b, and a lower cover portion 14c. The upper cover portion 14b is connected to the upper edge of the outer lens portion 14a and attached to the upper edge of the lamp body 12. The lower cover portion 14c is connected to the lower edge of the outer lens portion 14a and attached to the lower edge of the lamp body 12. The outer lens portion 14a is formed of a light-transmitting synthetic resin material, and the upper cover portion 14b and the lower cover portion 14c are formed of a suitable material, such as a general-purpose resin material. The upper cover portion 14b and the lower cover portion 14c may be configured not to transmit light. The front cover 14 may be manufactured, for example, by two-color molding.

[0018] Furthermore, the vehicle lighting fixture 10 includes a light source 18, a reflector 20, a first inner lens 21, a second inner lens 22, and a third inner lens 23, which are arranged within the lighting chamber 16.

[0019] The light source 18 comprises a plurality of light-emitting elements 18a and a substrate 18b on which these light-emitting elements 18a are mounted. The plurality of light-emitting elements 18a are arranged in a predetermined arrangement direction (in this example, the longitudinal direction of the vehicle light fixture 10) to form a row of light-emitting elements. The plurality of light-emitting elements 18a are arranged at equal intervals in the arrangement direction.

[0020] The light-emitting element 18a is a semiconductor light-emitting element such as a light-emitting diode (LED). The substrate 18b is a circuit board such as a printed circuit board and is configured to control the light-emitting element 18a mounted on the substrate 18b. The substrate 18b is connected to a power source outside the vehicle lighting device 10 via wiring connected thereto and is powered by it.

[0021] The substrate 18b may be supported by the reflector 20, thereby fixing the positional relationship between the light-emitting element 18a and the reflector 20. In the illustrated example, the substrate 18b is attached to the top of the reflector 20 by appropriate fixing means, such as screws. Alternatively, the light source 18 may be supported by the lamp body 12.

[0022] Figure 2 shows a schematic front view of the reflector 20, along with a schematic diagram showing an enlarged portion (the central part) of it. Also in Figure 2, for ease of understanding, the arrangement of the logo "ABCDE" of the design part 30 is shown superimposed on the reflector 20 with dashed lines. In the enlarged view, the arrangement of the light-emitting element 18a is shown with dashed lines. Figure 3 shows a cross-section along line A-A in Figure 2, that is, a vertical cross-section of the letter E in the logo "ABCDE" of the design part 30.

[0023] The reflector 20 is arranged along the row of light-emitting elements 18a. The reflector 20 has a plurality of concave reflective surfaces 20a arranged in the direction of the arrangement of the light-emitting elements 18a. These concave reflective surfaces 20a are configured to reflect the light emitted by the plurality of light-emitting elements 18a toward the inner lenses (21, 22, 23). The reflector 20 also has a plurality of reflective surface boundary portions 20b arranged alternately with the plurality of concave reflective surfaces 20a in the direction of the arrangement of the light-emitting elements 18a.

[0024] Similar to the light-emitting elements 18a, the concave reflective surfaces 20a are also arranged at equal intervals in the direction of arrangement. The pitch of the light-emitting elements 18a (i.e., the distance between two adjacent light-emitting elements 18a in the direction of arrangement) is equal to the pitch of the concave reflective surfaces 20a (i.e., the distance between the center positions 20c of two adjacent concave reflective surfaces 20a in the direction of arrangement).

[0025] Each concave reflective surface 20a has the same shape. The concave reflective surface 20a may be a concave aspherical surface such as a paraboloid, ellipsoid, or hyperboloid, or it may be a concave sphere. The center position 20c of each of the multiple concave reflective surfaces 20a in the direction of arrangement may be a position corresponding to the focal point of the concave reflective surface 20a.

[0026] In this embodiment, the position of each of the multiple light-emitting elements 18a in the array direction is offset from the respective center positions 20c of the multiple concave reflective surfaces 20a in the array direction. As a preferred example, as shown in the enlarged view in Figure 2 and in Figure 3, the position of each of the multiple light-emitting elements 18a in the array direction is aligned with the respective positions of the multiple reflective surface boundary portions 20b in the array direction.

[0027] For example, the reflector 20 may be a white component made of synthetic resin material. Alternatively, the reflector 20 may comprise a body made of synthetic resin material and a metal layer (for example, an aluminum vapor-deposited layer) covering the body. The reflector 20 may be fixed to the lamp body 12 by appropriate fixing means, such as screws.

[0028] The first inner lens 21, the second inner lens 22, and the third inner lens 23 are arranged so that reflected light from the concave reflective surface 20a of the reflector 20 is emitted through these inner lenses to the outer lens portion 14a of the front cover 14. The inner lenses (21, 22, 23) are positioned between the reflector 20 and the front cover 14 and are supported by the lamp body 12. The second inner lens 22 is positioned on the front cover 14 side relative to the first inner lens 21, that is, between the first inner lens 21 and the front cover 14. The third inner lens 23 is positioned on the reflector 20 side relative to the first inner lens 21, that is, between the first inner lens 21 and the reflector 20. These inner lenses are formed from a light-transmitting synthetic resin material or a suitable light-transmitting material such as glass.

[0029] The first inner lens 21 has a three-dimensional design element 21a on its surface. More specifically, the three-dimensional design element 21a is formed on the front surface of the first inner lens 21, that is, on the surface facing the outer lens portion 14a of the front cover 14. The three-dimensional design element 21a has a three-dimensional shape that represents the design represented by the design portion 30 shown in Figure 1 (in the illustrated example, a three-dimensional shape that represents the logo "ABCDE").

[0030] Figure 3 shows a cross-section along line A-A in Figure 2, that is, a vertical cross-section of the three-dimensional design element 21a of the letter E in the logo "ABCDE" of the design part 30. Figure 4 shows a schematic perspective view of the letter E in the logo "ABCDE" of the design part 30, viewed from the front.

[0031] In this example, the three-dimensional design element 21a is formed on the first inner lens 21 as a convex portion that protrudes forward from the front surface of the first inner lens 21, as shown in Figures 3 and 4. Alternatively, the three-dimensional design element 21a may be formed on the first inner lens 21 as a recess that is recessed backward from the front surface of the first inner lens 21.

[0032] The second inner lens 22 has a design opening 22a with an opening shape that matches the three-dimensional design element 21a of the first inner lens 21. The second inner lens 22 is positioned adjacent to the first inner lens 21 such that the three-dimensional design element 21a of the first inner lens 21 is positioned in the design opening 22a. The opening shape of the design opening 22a of the second inner lens 22 is determined to frame the three-dimensional design element 21a of the first inner lens 21. Furthermore, the three-dimensional design element 21a of the first inner lens 21 protrudes forward from the design opening 22a of the second inner lens 22. In this way, the design portion 30 shown in Figure 1 is composed of a combination of the first inner lens 21 and the second inner lens 22.

[0033] As shown in Figure 4, the second inner lens 22 may have a design element 22b on its surface. The design element 22b is formed on the front surface of the second inner lens 22, that is, on the surface facing the outer lens portion 14a of the front cover 14. Therefore, as shown in the figure, the three-dimensional design element 21a of the first inner lens 21 may be surrounded by the design element 22b of the second inner lens 22.

[0034] The design element 22b may include a light-transmitting region and a light-opaque region, and may be configured to express various planar designs, such as geometric patterns, letters, and symbols, by combining these regions. In this way, the planar design represented by the design element 22b may be arranged around the three-dimensional design element 21a. Figure 4 shows diagonal stripes as an example of the design element 22b.

[0035] In order to add the design element 22b to the second inner lens 22, a design film 24 may be attached to the front surface of the second inner lens 22, as shown in the enlarged view in Figure 3. The design element 22b may be a design pattern formed on the design film 24. Alternatively, the design element 22b may be directly formed on the front surface of the second inner lens 22 by an appropriate drawing method, such as painting or machining.

[0036] The third inner lens 23 functions as a light diffusing section positioned between the reflector 20 and the first inner lens 21. The third inner lens 23 may contain a light diffusing material. In addition, or instead, the third inner lens 23 may have an uneven surface shape for diffusing light. The first inner lens 21 and the second inner lens 22 may not contain a light diffusing material and may be transparent.

[0037] As shown in Figure 3, the light L1 emitted by the light-emitting element 18a of the light source 18 when it is lit is reflected by the concave reflective surface 20a of the reflector 20 and incident on the third inner lens 23. The light L1 is diffused by the third inner lens 23 and incident on the first inner lens 21 and the second inner lens 22. Furthermore, the light L1 is emitted from the first inner lens 21 and the second inner lens 22 through the outer lens portion 14a of the front cover 14 to the outside of the vehicle lamp 10. In this way, the first inner lens 21 and the second inner lens 22, i.e., the design portion 30 shown in Figure 1 (in this example, the logo "ABCDE"), emit light. At the same time, the vehicle lamp 10 provides its original lamp function (in this example, the illumination of the taillights).

[0038] Figure 5 is a schematic front view showing a part of the vehicle light fixture 10' according to a comparative example. In Figure 5, the central part of the reflector 20 of the vehicle light fixture 10' is shown in an enlarged view. In Figure 5, as in Figure 2, the arrangement of the light-emitting elements 18a is shown by dashed lines to understand the positional relationship between the light-emitting elements 18a and the concave reflective surface 20a.

[0039] As shown in Figure 5, in a typical design, each light-emitting element 18a can be positioned at the center 20c of the corresponding concave reflective surface 20a. However, the inventors have recognized that in such a design, the brightness distribution may be uneven in the longitudinal direction (left-right direction in the figure) of the vehicle light fixture 10', with the center 20d of the concave reflective surface 20a being relatively bright and other parts being dimmer. This unevenness can become more pronounced the closer the reflector 20 is to the design portion 30 (not shown in Figure 5). This unevenness in brightness is undesirable because it can affect the light emission of the design portion 30.

[0040] In contrast, according to this embodiment, the position of each of the multiple light-emitting elements 18a in the arrangement direction is offset from the respective center positions 20c of the multiple concave reflective surfaces 20a in the arrangement direction. By arranging the light-emitting elements 18a offset from the center positions 20c of the concave reflective surfaces 20a, the distance between the light-emitting elements 18a and the center positions 20c of the concave reflective surfaces 20a is increased, which suppresses the brightness of the central part of the concave reflective surfaces 20a and compensates for the brightness of other parts. In this way, the brightness distribution in the arrangement direction of the light-emitting elements 18a can be adjusted, and the uniformity of the light emission of the design portion 30 can be improved.

[0041] As described above, a preferred example is that the position of each of the multiple light-emitting elements 18a in the arrangement direction is aligned with the position of each of the multiple reflective surface boundary portions 20b in the arrangement direction. According to the inventors' research, by shifting the light-emitting elements 18a to the reflective surface boundary portions 20b, the uniformity of the light emission of the design portion 30 can be further improved.

[0042] As shown in Figure 3, the reflective surface boundary portion 20b may face the light-emitting element 18a behind the concave reflective surface 20a (towards the lamp body 12). This allows the reflective surface boundary portion 20b to block a portion of the light L2 from the light-emitting element 18a. The vehicle lamp 10 may use this light-blocking effect to adjust the brightness distribution of the design portion 30.

[0043] For adjusting the brightness distribution, the third inner lens 23 may have a convex portion 23a that protrudes from the surface of the third inner lens 23 (the surface on the reflector 20 side) so as to be close to the light-emitting element 18a. By using this convex portion 23a, more light from the light-emitting element 18a can be directed through the third inner lens 23 toward the first inner lens 21 and the second inner lens 22.

[0044] Also, according to the embodiment, the vehicle lamp 10 can three-dimensionally emit a design such as a logo or an emblem by combining the first inner lens 21 and the second inner lens 22.

[0045] The present invention is not limited to the above-described embodiments and modifications, and it is also possible to combine the embodiments and modifications or to make further modifications such as various design changes based on the knowledge of those skilled in the art. Embodiments or modifications that are combined or further modified in such a way are also included in the scope of the present invention. The new embodiments resulting from the combination of the above-described embodiments and modifications and the combination of the above-described embodiments and modifications and the following modifications have the effects of the combined embodiments, modifications, and further modifications.

[0046] In the above-described embodiment, the case where the vehicle lamp 10 is a center lamp arranged at the center of the rear part of the vehicle and functions as a tail lamp has been described as an example. However, the vehicle lamp 10 according to the embodiment may be a vehicle lamp arranged at other parts of the vehicle and having other functions. For example, the vehicle lamp 10 according to the embodiment may be a center lamp arranged at the center of the front part of the vehicle and may be configured to function as a clearance lamp. Also, the vehicle lamp 10 according to the embodiment may be applied to other vehicle lamps such as a stop lamp and a daytime running lamp. Alternatively, the vehicle lamp 10 according to the embodiment may be applied to an accessory lamp installed on the vehicle for decoration or a communication lamp that emits light to notify the surrounding area (pedestrians, other vehicles, etc.) of the vehicle of information related to driving support or autonomous driving.

[0047] Although the present invention has been described using specific terms based on the embodiments, the embodiments only illustrate one aspect of the principle and application of the present invention, and many modifications and changes in arrangement are permitted in the embodiments, as long as they do not depart from the spirit of the present invention as defined in the claims.
