Abstract

To enhance ornamental design property.SOLUTION: In an illumination device 10, a shield part 22 is provided between adjoined LEDs 42 and partitions inside of a ring groove part 20E of a case 20 in a circumferential direction. Therefore, the illumination device can shield light which spreads from the LED 42 to circumferential direction outside of the ring groove part 20E by the shield part 22 when lighting the LED 42. As a result, it can restrain the light irradiated from the LED 42 from illuminating other indicator part 50C adjoining to an indicator part 50C as lighting object from rear face. Accordingly, it can restrain irradiation area of an indicator 50 at lighting time from becoming unclear while forming the whole of indicator 50 in continuously annular shape. In addition, the shield part 22 is spaced apart from a rear face side of the indicator 50. Therefore, it can restrain the shield part 22 from being reflected on a front surface side of the indicator 50 in comparison with configuration which adjacently disposes the shield part 22 on the rear surface side of the indicator 50.SELECTED DRAWING: Figure 8

[0003] [Patent Document 1] Patent No. 6402384 Summary of the Invention [Problem to be solved by the invention]

[0004] Here, in a ring illumination such as the above-mentioned current display unit, a plurality of light sources are provided on the back surface of the indicator to be illuminated, and the light sources are arranged along the longitudinal direction of the indicator, thereby allowing the illumination of a part or the whole of the indicator. In other words, the illumination area of ​​the indicator can be changed. However, in this structure, for example, when illuminating a part of the indicator, if light from the light sources leaks to other parts of the indicator, the illumination range of the indicator becomes unclear, and the design of the indicator when illuminated may be deteriorated.

[0005] On the other hand, for example, by providing a plurality of independent indicator parts and arranging the respective indicator parts intermittently along the longitudinal direction of the indicator, it is possible to perform illumination with reduced light leakage. However, in this case, since the indicator is constituted by the indicator parts arranged intermittently, when the entire indicator is illuminated, the indicator is illuminated intermittently in the longitudinal direction. Therefore, even in this form, there is a possibility that the design quality will be reduced.

[0006] In consideration of the above, the present invention provides a lighting device that can improve design. [Means for solving the problem]

[0007] One or more embodiments of the present invention are an illumination device comprising: a linearly extending indicator; a case provided on the rear side of the indicator, the case having a groove portion extending along the longitudinal direction of the indicator and penetrating the indicator in the front-to-rear direction with an opening on one end side blocked by the indicator; a plurality of light sources provided within the other end of the groove portion and arranged in a line spaced apart relationship in the longitudinal direction and irradiating light onto the indicator to illuminate the indicator; and a shielding portion provided between adjacent light sources, partitioning the interior of the groove portion in the longitudinal direction and arranged at a distance on the rear side of the indicator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The lighting device 10 according to this embodiment will be described below with reference to the drawings. As shown in Fig. 1, the lighting device 10 is provided around a connector portion 70A of a charging inlet 70 in a vehicle V (automobile) and configured as a device that illuminates the periphery of the charging inlet 70 (connector portion 70A). Note that the arrows UP, FR, and OUT shown as appropriate in the drawings indicate the upper side, front side, and outer side in the vehicle width direction of the vehicle V, respectively. In the following description, when the up-down and front-rear directions are used, they refer to the up-down direction and the front-rear direction of the vehicle, unless otherwise specified.

[0011] As shown in FIGS. 1 to 3, charging inlet 70 is provided on a side of the rear of vehicle V. Charging box 72 is provided on the outer side of charging inlet 70 in the vehicle width direction, and charging box 72 exposes a part of charging inlet 70 to the outer side in the vehicle width direction. Charging box 72 is formed in a concave shape that opens to the outer side in the vehicle width direction. Specifically, bottom wall 72A of charging box 72 is inclined inward in the vehicle width direction as it goes upward, and exposure hole 72B is formed penetrating bottom wall 72A in the plate thickness direction. That is, exposure hole 72B penetrates along a direction inclined with respect to the vehicle width direction (directions along arrow A and arrow B in FIG. 2, hereinafter this direction is referred to as the inclination direction), and in the following description, the side in the direction of arrow A in FIG. 2 is referred to as the outer side in the inclination direction, and the side in the direction of arrow B in FIG. 2 is referred to as the inner side in the inclination direction. Exposure hole 72B is a hole that exposes connector portion 70A of charging inlet 70, and is formed in a generally elliptical shape with the vertical direction as the longitudinal direction when viewed from the outside in the tilt direction. Charging inlet 70 is disposed on the inner side in the tilt direction of charging box 72, and connector portion 70A is disposed within exposure hole 72B. Note that charging inlet 70 is inclined along the tilt direction.

[0012] An annular rib 72C (see FIG. 7) is formed on the outer edge in the inclined direction of exposure hole 72B of charging box 72. The annular rib 72C extends along the circumferential direction of exposure hole 72B and is formed around the entire circumferential direction of exposure hole 72B. A rib flange 72D (see FIG. 7) that protrudes radially inward from exposure hole 72B is formed at the tip of the annular rib 72C.

[0013] Vehicle V is also provided with a charging lid 74 (see FIG. 1) that opens and closes the opening of charging box 72, and connector section 70A is exposed by opening charging lid 74. As a result, by inserting a connector (not shown) connected to a charger or the like into connector section 70A of charging inlet 70, charging of the vehicle's rechargeable battery is performed from the charger or the like.

[0014] 2 to 8, the lighting device 10 is provided around the connector portion 70A of the charging inlet 70 so as to surround the connector portion 70A. The lighting device 10 includes a case 20, a case cover 30, a substrate 40, an indicator 50, and a control unit 60. Each component of the lighting device 10 will be described below.

[0015] (Regarding Case 20) The case 20 is made of a white resin material that is not transparent to light. The case 20 is formed in a substantially elliptical ring shape when viewed from the inclined direction, and is formed in a concave shape that is open inward in the inclined direction. That is, a case hole 20A is formed penetrating the inside of the case 20. Three fixing pieces 20B (see Figs. 4 and 6) are formed on the outer periphery of the case 20. The fixing pieces 20B at two locations protrude rearward from both ends in the vertical direction of the rear end of the case 20, and the other fixing piece 20B protrudes forward from a vertical middle part of the front end of the case 20. The case 20 is disposed on the inner side in the inclined direction of the edge of the exposure hole 72B of the charging box 72, and the fixing pieces 20B are fastened and fixed to the bottom wall of the charging box 72. When the case 20 is fixed to the charging box 72, the case hole 20A is located radially inside the exposure hole 72B when viewed from the outside in the inclined direction, and the connector portion 70A of the charging inlet 70 is disposed within the case hole 20A.

[0016] As shown in FIG. 7, the inner periphery of the case 20 has a substantially elliptical double-tube structure with the inclination direction as the axial direction. That is, the inner periphery of the case 20 is formed with an inner tube 20C constituting the inner periphery of the case hole 20A and an outer tube 20D arranged radially outside the inner tube 20C, and the inner tube 20C and the outer tube 20D extend along the circumferential direction of the case hole 20A. The portion between the inner tube 20C and the outer tube 20D is a ring groove 20E as a groove, and the ring groove 20E penetrates in the inclination direction. That is, the ring groove 20E extends in a curved shape in the circumferential direction of the connector part 70A of the charging inlet 70 when viewed from the outside in the inclination direction, and is formed over the entire circumference of the connector part 70A in the circumferential direction. The inner tube 20C constitutes the inner wall part of the ring groove 20E in the width direction, and the outer tube 20D constitutes the outer wall part of the ring groove 20E in the width direction. The outer end portions (one end portion) in the inclination direction of the inner cylinder 20C and the outer cylinder 20D protrude outward in the inclination direction from the case 20, and are disposed close to the radially inner side of the exposure hole 72B. The one end portion of the inner cylinder 20C is disposed with a predetermined gap on the inner side in the inclination direction of the rib flange 72D of the charging box 72. The inner end portion (the other end portion) in the inclination direction of the outer cylinder 20D is disposed at a position one step lower outward in the vehicle width direction than the inner end portions in the vehicle width direction of the inner cylinder 20C and the outer peripheral wall 20G of the case 20.

[0017] As shown in FIG. 5 and FIG. 8, a plurality of shielding parts 22 (14 in this embodiment) are provided in the ring groove 20E of the case 20. The shielding parts 22 are connected to the inner tube 20C and the outer tube 20D to connect them. The shielding parts 22 are arranged side by side at a predetermined interval in the circumferential direction of the ring groove 20E. As a result, the inside of the ring groove 20E is divided in the circumferential direction by the shielding parts 22 adjacent in the circumferential direction of the ring groove 20E. The shielding parts 22 are formed in a substantially V-shaped rib shape that is open toward the inside in the inclination direction when viewed from the width direction of the ring groove 20E. That is, an inclined surface 22A is formed on each side surface of the shielding parts 22 that divides the ring groove 20E, and the pair of inclined surfaces 22A are inclined in a direction approaching each other as they move toward the outside in the inclination direction. The intersection of the pair of inclined surfaces 22A is the apex 22B, and the apex 22B constitutes the outer end of the shielding part 22 in the inclination direction. The angle of the inclined surface 22A is set so that the angle between the pair of inclined surfaces 22A is an acute angle when viewed from the width direction of the ring groove part 20E. The apex 22B is disposed with a predetermined gap on the inner side in the inclination direction relative to the indicator 50 described later. Meanwhile, the inner end surface in the inclination direction of the shielding part 22 is formed flush with the inner end surface in the inclination direction of the outer tube 20D. In this embodiment, most of the side surface of the shielding part 22 is constituted by the inclined surface 22A, but the entire side surface of the shielding part 22 may be constituted by the inclined surface 22A.

[0018] (About case cover 30) 2 and 6, the case cover 30 is formed in a plate shape with the plate thickness direction being the inclination direction, and is formed in a substantially elliptical ring shape when viewed from the inclination direction. The case cover 30 is disposed on the inner side of the case 20 in the vehicle width direction and fastened and fixed to the case 20 so as to close the opening on the inner side in the inclination direction of the case 20.

[0019] (Regarding the substrate 40) 2 and 5 to 8, similar to the case cover 30, the substrate 40 is formed in a plate shape with the plate thickness direction being the inclination direction, and is formed in a substantially elliptical ring shape when viewed from the inclination direction. The substrate 40 is housed in the case 20, and is fastened and fixed to the case 20 together with the case cover 30. The substrate 40 is disposed adjacent to the inner side in the inclination direction of the outer cylinder 20D, and closes the opening on the inner side in the inclination direction of the ring groove portion 20E.

[0020] A plurality of LEDs 42 (14 in this embodiment) are provided as light sources on the surface (outer surface in the inclined direction) of the substrate 40. The LEDs 42 are arranged in the inner end of the ring groove 20E in the inclined direction of the case 20, and are arranged at a predetermined interval along the circumferential direction of the ring groove 20E. Specifically, the LEDs 42 are arranged between the adjacent shielding parts 22 in the ring groove 20E. That is, the LEDs 42 and the shielding parts 22 are arranged alternately in the circumferential direction of the ring groove 20E (see FIG. 5). The LEDs 42 are electrically connected to the control unit 60, which will be described later, and are configured to irradiate light from the LEDs 42 outward in the inclined direction to illuminate the indicator 50, which will be described later, when the control unit 60 turns on the LEDs 42.

[0021] (About Indicator 50) As shown in Figs. 2 to 4 and Figs. 6 to 8, the indicator 50 is made of a resin material that can transmit light. Specifically, the indicator 50 is made of a smoke-colored resin material. In Figs. 3 and 4, the indicator 50 is painted gray. Here, in this embodiment, the color scheme of the resin material and the thickness dimension of the indicator 50 are set so that the visible light transmittance of the indicator 50 is a predetermined value or less (for example, 20% or less in this embodiment). The indicator 50 is formed in a substantially elliptical ring shape when viewed from the inclination direction, and the cross section of the indicator 50 when viewed from the circumferential direction is formed in a substantially rectangular shape. An outer flange 50A is formed in the thickness direction intermediate portion of the outer periphery of the indicator 50, and the outer flange 50A is formed over the entire circumference of the indicator 50 in the circumferential direction. Also, an inner flange 50B is formed in the thickness direction intermediate portion of the inner periphery of the indicator 50, and the inner flange 50B is formed over the entire circumference of the indicator 50 in the circumferential direction.

[0022] The indicator 50 is fitted into the outer end of the ring groove 20E in the case 20 in the inclination direction, and is fixed to the case 20, and closes the opening of the ring groove 20E on the outer side in the inclination direction. That is, the indicator 50 extends in a curved shape in the circumferential direction of the connector portion 70A of the charging inlet 70 when viewed from the outside in the inclination direction, and is formed over the entire circumference of the connector portion 70A in the circumferential direction. When the indicator 50 is fixed to the case 20, the outer flange 50A is disposed adjacent to the outer side in the inclination direction of the outer tube 20D of the case 20, and is disposed on the inner side in the inclination direction of the rib flange 72D of the charging box 72 with a predetermined gap therebetween. When the indicator 50 is fixed to the case 20, the inner flange 50B is disposed adjacent to the outer side in the inclination direction of the inner tube 20C of the case 20, and is disposed adjacent to the inner side in the inclination direction of the spacer 76 provided on the inner tube 20C of the case 20. Spacer 76 is formed in a substantially elliptical ring shape when viewed in an inclined direction, and is disposed to straddle inner cylinder 20C and charging inlet 70 so as to make the gap between inner cylinder 20C and charging inlet 70 invisible. Spacer 76 also ensures waterproofing and dustproofing between inner cylinder 20C and charging inlet 70.

[0023] Also, the part of the indicator 50 facing the LED 42 is the indicator part 50C (FIGS. 4 and 8), and the indicator part 50C is formed in a band shape extending in the circumferential direction of the indicator 50. That is, the indicator 50 has a plurality of indicator parts 50C (14 parts in this embodiment) corresponding to the plurality of LEDs 42, and the indicator parts 50C are continuously arranged along the circumferential direction of the indicator 50. In other words, the LED 42 and the indicator part 50C facing each other in the inclination direction form a pair, and the LED 42 illuminates the paired indicator part 50C from the back side to illuminate the indicator part 50C. Note that in FIG. 4 and FIG. 8, the boundary part between adjacent indicators 50 is illustrated by a dotted line.

[0024] (Regarding the control unit 60) 7, as described above, the control unit 60 is electrically connected to the LEDs 42 and controls the turning on and off of the LEDs 42. Specifically, when the connector of the charger is not inserted into the connector portion 70A of the charging inlet 70, the control unit 60 turns on all of the LEDs 42 and illuminates the indicator 50 in a ring shape. On the other hand, when the connector is inserted into the connector portion 70A, the number of LEDs 42 to be turned on is determined according to the charge level of the rechargeable battery of the vehicle V. That is, the indicator 50 is illuminated in a strip shape, and when the rechargeable battery is fully charged, the indicator 50 is illuminated in a ring shape.

[0025] (Action and effect) Next, the effects of this embodiment will be described.

[0026] In the lighting device 10 configured as described above, when the connector of the charger is not inserted into the connector portion 70A of the charging inlet 70, the control unit 60 turns on all the LEDs 42 and illuminates the indicator 50 in a ring shape. This allows the user to easily recognize the position of the charging inlet 70. This improves the user's convenience. On the other hand, when the connector of the charger is inserted into the connector portion 70A of the charging inlet 70, the number of the LEDs 42 to be turned on is determined according to the charge amount of the rechargeable battery of the vehicle V. That is, for example, when the charge amount of the charger of the vehicle V is zero, all the LEDs 42 are turned off and the indicator 50 is in a non-illuminated state. When the charge amount of the charger of the vehicle V increases, the number of the turned on LEDs 42 increases and the indicator 50 is illuminated in a strip shape. Then, when the charger is fully charged, all the LEDs 42 are turned on and the indicator 50 is illuminated in a ring shape. This allows the user to easily recognize the charging state of the rechargeable battery.

[0027] In addition, in the lighting device 10, the indicator 50 is formed in an annular (ring-like) shape so as to surround the connector portion 70A of the charging inlet 70. In other words, the indicator 50 extends in a curved shape in the circumferential direction of the connector portion 70A, and is formed over the entire circumference of the connector portion 70A in the circumferential direction. Furthermore, a plurality of LEDs 42 for illuminating the indicator 50 are provided on the back side (inner side in the tilt direction) of the indicator 50, and the plurality of LEDs 42 are arranged in a line at a predetermined interval in the circumferential direction of the indicator 50. When the LED 42 is turned on, light is emitted from the LED 42 toward the indicator 50 side (outer side in the tilt direction). Therefore, the indicator portion 50C that is paired with the turned-on LED 42 is illuminated, and the indicator 50 is illuminated in a strip shape.

[0028] In the lighting device 10, as described above, the indicator 50 is formed in an annular shape, and therefore the multiple indicator parts 50C constituting the indicator 50 are continuously arranged in the circumferential direction of the indicator 50. Therefore, when the LED 42 illuminates the pair of indicator parts 50C from the back side, the light spreading from the LED 42 to the outside in the circumferential direction of the ring groove part 20E may illuminate the indicator part 50C adjacent to the indicator part 50C to be illuminated. In this case, in addition to the indicator part 50C to be illuminated, the adjacent indicator part 50C is also illuminated, so that the illumination range of the indicator 50 becomes unclear. As a result, the design of the lighting device 10 may be deteriorated.

[0029] Here, in the lighting device 10, the shielding portion 22 is provided between the adjacent LEDs 42, and divides the inside of the ring groove portion 20E of the case 20 in the circumferential direction. Therefore, when the LEDs 42 are turned on, the light that spreads from the LEDs 42 to the outside in the circumferential direction of the ring groove portion 20E can be shielded by the shielding portion 22. As a result, it is possible to prevent the light emitted from the LEDs 42 from illuminating the other indicator portions 50C adjacent to the indicator portion 50C to be illuminated from the back side. Therefore, while forming the entire indicator 50 into a continuous ring shape, it is possible to prevent the illumination range of the indicator 50 from becoming unclear when illuminated. In addition, the shielding portion 22 is disposed at a distance from the back side of the indicator 50. Therefore, compared to a configuration in which the shielding portion 22 is disposed adjacent to the back side of the indicator 50, it is possible to prevent the shielding portion 22 from being reflected on the front side of the indicator 50. As a result, it is possible to improve the design of the lighting device 10.

[0030] Moreover, the indicator 50 is made of a smoke-colored resin material. That is, the visible light transmittance of the indicator 50 can be set lower than when the indicator 50 is made of a milky-white resin material. Therefore, when the LED 42 illuminates the paired indicator part 50C, the light passing through the indicator part 50C to be illuminated can be prevented from leaking to the adjacent indicator part 50C. This further prevents the illumination range of the indicator 50 from becoming unclear.

[0031] In addition, inclined surfaces 22A are formed on both side surfaces of the shielding portion 22 that divide the inside of the ring groove portion 20E, and the inclined surfaces 22A are inclined in a direction approaching each other as they approach the indicator 50 side (outer side in the inclination direction). As a result, when the LED 42 is turned on, the light spreading from the LED 42 to the outer side in the circumferential direction of the ring groove portion 20E can be reflected by the inclined surfaces 22A to the end side of the paired indicator portion 50C. That is, the shielding portion 22 that shields the light spreading from the LED 42 to the outer side in the circumferential direction of the ring groove portion 20E can also function as a reflector that reflects light to the end of the indicator portion 50C. As a result, the end of the indicator portion 50C that is the illumination target can be well illuminated. In particular, in the indicator 50 made of a smoke-colored resin material, the luminance of the indicator portion 50C when illuminated is reduced, so that the luminance of the indicator portion 50C when illuminated can be effectively increased.

[0032] In addition, the shielding portion 22 is integrally formed with the case 20, and the case 20 is white. This makes it possible to suppress a decrease in the brightness of the light reflected by the inclined surface 22A. That is, while suppressing a decrease in the brightness of the light spreading from the LED 42 to the outside in the circumferential direction of the ring groove portion 20E, the inclined surface 22A can reflect the light toward the end side of the indicator portion 50C. Therefore, it is possible to suppress uneven illumination of the indicator portion 50C that is the illumination target, and to illuminate the indicator portion 50C well.

[0033] Moreover, by forming the shielding portion 22 integrally with the case 20, the inner cylinder 20C and the outer cylinder 20D that form the ring groove portion 20E can be connected. This allows the shielding portion 22 to ensure the strength of the inner peripheral portion of the case 20.

[0034] Moreover, the shielding portion 22 is formed in a substantially V-shaped rib shape that is open toward the inside in the inclination direction when viewed from the width direction of the ring groove portion 20E. This allows the shielding portion 22 to be lightweight while ensuring the strength of the inner periphery of the case 20. Furthermore, by forming the shielding portion 22 in a substantially V-shaped rib shape, the top portion 22B of the shielding portion 22 is formed in a wedge shape. Therefore, when viewed from the outside in the inclination direction, the top portion 22B of the shielding portion 22 is formed in a line shape that follows the width direction of the ring groove portion 20E. This effectively prevents the top portion 22B of the shielding portion 22 from being reflected in the indicator 50 when viewed from the outside in the inclination direction.

[0035] In this embodiment, the light color of the LED 42 is not particularly specified, but the control unit 60 may be configured to change the light color of the LED 42 to change the illumination mode for the indicator 50. For example, the light color of the LED 42 during charging may be set to green, and if a malfunction occurs during charging, the light color of the LED 42 may be changed from green to red.

[0036] In addition, in the present embodiment, the lighting device 10 is provided around the connector portion 70A of the charging inlet 70 in the vehicle V, but the lighting device 10 may be provided in another portion of the vehicle V. For example, the lighting device 10 may be provided on the dashboard, door trim, center console, overhead console, door handle, side door, etc. of the vehicle V. In this case, for example, the indicator 50 may be formed to extend linearly in the longitudinal direction of the dashboard, and the indicator 50 may illuminate the interior of the vehicle V.

[0037] In addition, in this embodiment, the indicator 50 is formed in an elliptical ring shape. In other words, the indicator 50 extends in a curved shape in the circumferential direction of the connector part 70A and is formed around the entire circumference of the connector part 70A in the circumferential direction. Alternatively, the indicator 50 may be formed in a partially open elliptical ring shape. That is, the indicator 50 may be formed in a curved band shape along the circumferential direction of the connector part 70A. In this case, the ring groove 20E of the case 20 is also formed in a partially open elliptical ring shape when viewed from the outside in the inclined direction, similar to the indicator 50.
