Summary of the Invention

Problem to be Solved by the Invention

[0004] By the way, in the lighting device according to Patent Document 1, the pattern or the like that appears when the illumination is turned on is constant, and the pattern does not change. If the pattern or the like visible to a viewer can be changed, the designability can be further enhanced, which is preferable.

[0005] An object of the present disclosure is to provide a lighting device with high designability.

Means for Solving the Problem

[0006] According to the present disclosure, the lighting device includes an illuminable lighting unit, and a resin member which is a resin member that is displaceable relative to an irradiation range irradiated by the lighting unit, The resin member includes a step forming portion having a plurality of step portions formed in a stepped shape, and a decorative portion that is in close contact with the step forming portion, When positioned within the irradiation range, the step portion has a larger protrusion amount as it moves away from the lighting unit so that the step portion can reflect the light from the lighting unit. The lighting device is provided, wherein the decorative part has a reflective part that reflects the light of the lighting part when it is located within the illumination range. [Effects of the Invention]

[0007] According to this disclosure, it is possible to provide a lighting device with a high level of design appeal. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0009] Embodiments of the present invention will be described below with reference to the attached drawings. Note that the embodiments shown in the attached drawings are examples of the present invention, and the present invention is not limited to these embodiments.

[0010] <Embodiment> Embodiments will be described based on the drawings.

[0011] Reference is made to Figure 1. The lighting device 20 is, for example, mounted on an air-conditioning outlet device Ao of a vehicle. The air-conditioning outlet device Ao is used as a blowout device for a vehicle air conditioner. The air-conditioning outlet device Ao is, for example, provided at the front portion of the vehicle cabin, and blows air toward the occupant.

[0012] Reference is made to Figure 2. The air-conditioning outlet device Ao has a housing 10 inside which air is blown, and the lighting device 20 is supported by this housing 10.

[0013] The housing 10 has an inlet 11 into which blown air is introduced, an air outlet 12 that faces the vehicle cabin and blows air toward the vehicle cabin, a narrow portion 13 formed between the inlet 11 and the air outlet 12 and having an area smaller than the area of the air outlet 12, and inner wall portions 15 and 16 extending from the narrow portion 13 to the air outlet 12 substantially parallel to the upper and lower surfaces of the resin member 30.

[0014] Reference is made to Figure 1. The air outlet 12 has a substantially rectangular shape. Hereinafter, the direction parallel to the long side 12a of the air outlet 12 (the vehicle width direction in this embodiment) is referred to as the first direction, and the direction parallel to the short side 12b which is a side shorter than the long side 12a (the vertical direction in this embodiment) is referred to as the second direction.

[0015] In the case where the air outlet 12 is the vertically long air-conditioning outlet device Ao, the first direction is the vertical direction, and the second direction is the vehicle width direction (and / or the vehicle front-rear direction). Further, the first direction may be the vehicle front-rear direction, and the second direction may be the vertical direction (or the vehicle width direction).

[0016] Reference is made to Figure 2. The lighting device 20 includes a resin member 30 provided inside the housing 10, a first drive mechanism 40 that displaces the resin member 30 along the air blowing direction, a second drive mechanism 50 that swings the resin member 30 in the vertical direction (the direction parallel to the short side of the air outlet), and lighting units 60 and 70 capable of irradiating the downstream end of the resin member 30.

[0017] Reference is made to Figure 1. The resin member 30 constitutes a part of the lighting device 20, and is a member that adjusts the volume of blown air blown out from the air outlet 12 and controls the direction of the blown air. The resin member 30 is provided extending across the first direction.

[0018] Reference is made to Figure 2. In the air blowing mode, the resin member 30 is located between the narrow portion 13 and the air outlet 12, and at substantially the center of the air outlet 12 with the second direction as a reference. The resin member 30 has a shape in which a substantially fan-shaped cross section extends in the first direction. The resin member 30 includes a pin portion 32 which is a pin formed at the upstream end and connected to the round hole of the first drive mechanism 40, tapered portions 33, 33 extending so as to spread downstream from the pin portion 32 respectively, a step forming portion 34 formed in an arc shape so as to connect the downstream ends of these tapered portions 33, 33, and a decorative portion 35 that is overlaid on the step forming portion 34 and irradiated by the lighting units 60, 70.

[0019] Reference is also made to Figure 3. The back surface (upstream side surface) of the step forming portion 34 is formed in an arch shape. Further, the side surface of the step forming portion 34 extends linearly from the pin portion 32 on the extension line of the tapered portions 33, 33.

[0020] Hereinafter, of the surfaces (downstream side surfaces) of the step forming portion 34, the portions closest to the lighting units 60 and 70 respectively are referred to as reference surface portions 34o. The downstream side surface of the step forming portion 34 is constituted by the reference surface portions 34o, and step portions 34a to 34c formed in a stepped shape so as to protrude from the reference surface portions 34o. The step portions 34a to 34c may have two steps, or four or more steps.

[0021] The amount of protrusion of the stepped sections 34a to 34c from the reference surface 34o increases as they move away from the lighting sections 60 and 70. Each stepped section 34a to 34c has risen portions 34a1 to 34c1 that are raised from the reference surface 34o or adjacent stepped sections 34a and 34b, and tread portions 34a2 to 34c2 that extend substantially perpendicularly from the ends of these risers 34a1 to 34c1. The risers 34a1 to 34c1 extend in a direction intersecting (approximately perpendicular to) the light emitted from the lighting sections 60 and 70, while the tread portions 34a2 to 34c2 extend in a direction along the light emitted from the lighting sections 60 and 70.

[0022] The angle formed by the risers 34a1-34c1 and the treads 34a2-34c2 is preferably 90° or greater. Reflective material may be provided on the stepped portion 34a-34c (at least the portion including the angle formed by the risers 34a1-34c1 and the treads 34a2-34c2) to reflect light more easily. The reflective material can be made of vapor-deposited metal, paint, or tape.

[0023] Although the back surface of the step-forming portion 34 is exemplified as being arc-shaped, it may also be formed in a straight line. Furthermore, the tapered portion 33 and the step-forming portion 34 may be a single integrated component. Also, the lengths of the risers 34a1 to 34c1 and the treads 34a2 to 34c2 may be the same, or they may differ from step to step. In addition, the step portions 34b, 34b flanking the step portion 34c may have different shapes, or they may have the same shape. The same applies to the step portions 34a, 34a.

[0024] The decorative portion 35 is made of a transparent material such as acrylic or glass. The back surface of the decorative portion 35 is formed in a concave shape along the shape of the stepped portions 34a to 34c. As a result, the decorative portion 35 is in close contact with the surface of the stepped portion 34. The side surface of the decorative portion 35 extends linearly from the pin portion 32. The surface of the decorative portion 35 is formed in an arc shape centered on the pin portion 32.

[0025] Refer to Figure 4. Reflective portions 35a and 35b are formed on the surface of the decorative portion 35 that is in contact with the tread portion 34c2 (step portion 34c), and are capable of reflecting light from the lighting portions 60 and 70 (see Figure 2). Numerous reflective portions 35a and 35b are formed, including on the surfaces that are in contact with the tread portions 34a2 and 34b2 (see Figure 3).

[0026] The reflective parts 35a and 35b have a wedge shape, but they may have any other shape as long as they can reflect light in the direction from which the viewer is looking. The reflective parts 35a and 35b may be formed on the decorative part 35 in a later process, or they may be formed at the same time as the decorative part 35 during resin molding.

[0027] Furthermore, the reflective sections 35a and 35b consist of two types: a first reflective section 35a and a second reflective section 35b. The first reflective section 35a has an inclined surface so as to reflect light incident from below (one end of the decorative section 35) backward (towards the viewer). The second reflective section 35b has an inclined surface so as to reflect light incident from above (the other end of the decorative section 35) backward (towards the viewer). The first reflective section 35a and the second reflective section 35b may be formed in the same location. In this case, both light incident from below and light incident from above can be reflected backward.

[0028] Refer to Figure 3 as well. Note that the decorative portion 35 may be a smoke-like, semi-transparent material. If a semi-transparent material is used, light can be diffused. With respect to the longitudinal direction, the boundary between the kick plate portion 34a1~34c1 and the tread portion 34a2~34c2 does not have to be formed in a straight line. It can be formed into a predetermined pattern or into letters.

[0029] Furthermore, the reflective portions 35a and 35b may be formed on the surface or inside the decorative portion 35.

[0030] Refer to Figure 1. The first drive mechanism 40 includes, for example, a first motor 41 which is a stepping motor that operates when power is applied, a 1-1 gear 42 which is a gear that rotates when the first motor 41 operates, a first shaft member 43 which is a shaft that passes through the 1-1 gear 42 and is rotatably supported by the housing 10, and 1-2 gears 44 which are gears fixed to both ends of the first shaft member 43 and rotate when the 1-1 gear 42 rotates.

[0031] Refer to Figure 2. The first drive mechanism 40 further includes a 1-3 gear 45 which meshes with the 1-2 gear 44, and a rack section 46 which meshes with the 1-3 gear 45 and converts rotational motion into linear motion. The rack section 46 has a round hole at its tip and is connected to the resin member 30 through this round hole. The resin member 30 is connected to the rack section 46 so as to be able to swing in a second direction (up and down direction).

[0032] Refer to Figure 1. The gear provided on the first motor 41 is called the first drive gear 41a, which transmits the driving force of the first motor 41.

[0033] Furthermore, the first motor 41 may be a motor other than a stepping motor. Also, the gears 42, 44, and 45 (see Figure 2 for gear 1-3 45) that transmit the driving force of the first motor 41 to the rack section 46 may consist of one or two gears, or four or more gears.

[0034] Refer to Figure 2 as well. When the first motor 41 is activated based on information from the temperature sensor or the operator's actions, the 1-1 gear 42, the first shaft member 43, the 1-2 gear 44, and the 1-3 gear 45 rotate. As a result, the rack section 46 is displaced along the direction of airflow, and the resin member 30 is displaced along the direction of airflow. In other words, the resin member 30 is displaced along the flow path.

[0035] Refer to Figure 5. The second drive mechanism 50 includes, for example, a second motor 51 which is a stepping motor that operates when power is applied, a 2-1 gear 52 which rotates when the second motor 51 operates, a sector gear 53 which is a sector gear that rotates when the 2-1 gear 52 rotates, a 2-2 gear 54 which meshes with the sector gear 53 and rotates when the sector gear 53 rotates, and a resin member support part 56 which is rotatable in conjunction with the 2-2 gear 54 and can support the resin member 30.

[0036] Furthermore, the second motor 51 may be a motor other than a stepping motor. Also, the gears 52-54 that transmit the driving force of the second motor 51 to the resin member support part 56 may consist of one or two gears, or four or more gears. In addition, sector gears may not be included.

[0037] The resin member support portion 56 is connected to the resin member 30 in the blowing mode and is separated from the resin member 30 in the blowing stop mode. In other words, the resin member 30 is provided so as to be displaceable relative to the resin member support portion 56, so as to be connected to the resin member support portion 56 in the blowing mode and separated from the resin member support portion 56 in the blowing stop mode.

[0038] When the second motor 51 is activated based on information from the temperature sensor or the operator's actions, the 2-1 gear 52, 2-2 gear 52, sector gear 53, 2-3 gear 54, and resin member support part 56 rotate. When the resin member 30 is in a blowing mode in which it can blow air, the resin member 30 swings in the second direction together with the resin member support part 56.

[0039] Furthermore, the second drive mechanism 50 only needs to be capable of displacing the resin member 30 in the second direction. That is, the second drive mechanism 50 may be a mechanism that moves the resin member 30 linearly in the second direction.

[0040] Refer to Figure 2. The illumination units 60 and 70 are provided on both the lower and upper parts of the resin member 30. At least one of the illumination units 60 and 70 illuminates the decorative part 35 of the resin member 30 as it is displaced in the direction along the flow path and in the second direction. Hereinafter, the illumination unit 60 located below (one end) of the resin member 30 may be referred to as the first illumination unit 60, and the illumination unit 70 located above (the other end) of the resin member 30 may be referred to as the second illumination unit 70. The illumination units 60 and 70 are provided flush with the inner wall parts 15 and 16 and do not protrude toward the flow path side.

[0041] Furthermore, the lighting units 60 and 70 do not necessarily need to be provided both above and below. They may be provided only below or above the resin member 30. Also, the lighting units 60 and 70 do not necessarily need to illuminate the decorative part 35 vertically; they may illuminate it at an angle.

[0042] The first lighting unit 60 includes a first light source 61 that is lit when power is supplied, and a first light guide 62 that guides the light from the first light source 61 toward the decorative part 35. The first light guide 62 is provided facing the entire resin member 30 along the first direction. The part of the inner wall 25 facing the tip of the first light guide 62 is open. The position of the first light source 61 and the shape of the first light guide 62 can be changed as appropriate depending on the irradiation position and irradiation range.

[0043] The configuration of the second illumination unit 70 is the same as that of the first illumination unit 60. The second illumination unit 70 includes a second light source 71 that is lit when power is applied, and a second light guide 72 that guides the light from the second light source 71 toward the decorative part 35. The second light guide 72 is provided facing the entire resin member 30 along the first direction. The part of the inner wall 26 facing the tip of the second light guide 72 is open. The position of the second light source 71 and the shape of the second light guide 72 can be changed as appropriate depending on the irradiation position and irradiation range.

[0044] For example, LEDs can be used for the light sources 61 and 71. Also, for example, acrylic can be used for the light guides 62 and 72. The blinking of the light sources 61 and 71 can be controlled by a control unit (not shown), which can light up only the first light source 61, only the second light source 71, both light sources 61 and 71, or turn them off.

[0045] Furthermore, the light sources 61 and 71 may be provided in a manner that allows them to be displaced relative to the resin member 30.

[0046] Next, the operation of the air conditioning outlet device Ao and the lighting device 20 will be explained.

[0047] Figure 2 shows the air conditioning outlet device Ao in the fan mode. In the normal fan mode, the resin member 30 is located between the narrow section 13 and the outlet 12, and approximately in the middle of the flow path with reference to the second direction. In the normal fan mode, the air blown from an air conditioner (not shown) is divided vertically by the resin member 30 and blown out vertically from the outlet 12.

[0048] Refer to Figure 6. When switching from the blowing mode to the blowing stop mode, the first fin mechanism 40 is activated to displace the resin member 30 upstream. As the resin member 30 comes into contact with the narrow section 13, the flow path is blocked and the blowing stops. In other words, air is no longer blown out from the outlet 12.

[0049] When switching from the fan-off mode to the fan-on mode, the first motor 41 is reversed. This causes the resin member 30 to be displaced downstream, enabling air to be blown into the vehicle interior.

[0050] Furthermore, even when in fan mode, the wind speed of the blown air can be adjusted by moving the position of the resin component 30. Fine-tuning of the position in fan mode will be described later.

[0051] Refer to Figure 5. When the resin member 30 is in the blowing mode, the second fin mechanism 50 can be activated to swing the resin member 30. Depending on the position the resin member 30 is facing, the proportion of blown air passing above and below the resin member 30 changes, and the direction of the blown air is changed.

[0052] More specifically, the rotation of the second motor 51 causes the 2-1 gear 52 and the sector gear 53 to rotate. The rotation of the sector gear 53 causes the 2-2 gear 54 and the resin member support part 56 to rotate. The rotation of the resin member support part 56 causes the resin member 30 to rotate as well. This changes the orientation of the resin member 30.

[0053] Refer to Figures 7A and 7B. Figures 7A and 7B show a simplified illustration of the lighting device 20 according to an embodiment. In the state shown in Figure 7A, all stepped portions 34a to 34c of the resin member 30 are within the illumination range IA of the lighting units 60 and 70. At this time, light is reflected at the corners of the stepped portions 34a to 34c, and the occupant (viewer) sees three linear beams of light vertically.

[0054] Refer to Figures 8A and 8B. Figures 8A and 8B show a simplified illustration of the lighting device 20 according to an embodiment. The resin member 30 shown in Figure 8A is located further downstream than the resin member 30 shown in Figure 7A. In the state shown in Figure 8A, only one stepped portion 34a of the resin member 30 is within the illumination range IA. Stepped portions 34b and 34c are located outside the illumination range IA. At this time, light is reflected at the corner of the stepped portion 34a, and the occupant (viewer) sees one linear beam of light above and one below.

[0055] Furthermore, it is not necessary for all stepped portions 34a to 34c to be in the illumination range IA at the same time. That is, the steps between the stepped portions 34a to 34c may be made larger so that one stepped portion (e.g., 34c) leaves the illumination range IA before another stepped portion (e.g., 34a) enters the illumination range IA. In this case, the area that glows will change due to the displacement.

[0056] Refer to Figures 7C and 7D. Figures 7C and 7D show a simplified illustration of the comparative example lighting device 120. As shown in Figure 7C, in the comparative example lighting device 120, the stepped portions 134a to 134c are formed to be more concave than the reference surface portion 34o.

[0057] In the state shown in Figure 7C, all stepped portions 134a to 134c of the resin member 130 are within the illumination range IA of the illumination units 60 and 70. However, the light emitted from the illumination units 60 and 70 is blocked by the sides of the resin member 130 and does not hit the stepped portions 134a to 134c. As a result, the light does not reflect at the corners of the stepped portions 134a to 134c, and the occupants (viewers) do not see any vertical lines of light.

[0058] Refer to Figure 9A. When the first light source 61 is lit and the decorative part 35 is located within the illumination range IA, the light emitted from the first light source 61 is reflected towards the viewer Mn by the first reflector 35a. Refer to Figure 9C as well. Because a large number of fine first reflectors 35a are formed, the viewer Mn recognizes a specific pattern.

[0059] Refer to Figure 9A. When the second light source 71 is lit and the decorative part 35 is located within the illumination range IA, the light emitted from the second light source 71 is reflected towards the viewer Mn by the second reflecting part 35b. Refer to Figure 9B as well. Because a large number of fine second reflecting parts 35b are formed, the viewer Mn recognizes a specific pattern different from that reflected by the first reflecting part 35a. At this time, the patterns that appear on the decorative part 35 include not only common patterns such as geometric patterns, gradients, and natural patterns, but also letters and the like.

[0060] When only the first light source 61 is lit, the observer Mn recognizes the pattern that emerges from the light reflected by the first reflector 35a, and when only the second light source 71 is lit, the observer Mn recognizes the pattern that emerges from the light reflected by the second reflector 35b. Furthermore, when both light sources 61 and 71 are lit simultaneously, the observer Mn recognizes both patterns that emerge from the light reflected by the reflectors 35a and 35b.

[0061] Refer to Figure 7A as well. When both the stepped portions 34a to 34c and the decorative portion 35 are within the illumination range IA, the viewer Mn may perceive both the pattern raised by the stepped portions 34a to 34c and the pattern raised by the reflective portions 35a and 35b.

[0062] The lighting device 20 described above is summarized below.

[0063] Refer to Figure 7A. Firstly, the lighting device 20 includes lighting units 60 and 70 that can be lit, and a resin member 30 which is a resin component that can be displaced relative to the illumination range IA irradiated by the lighting units 60 and 70. The resin member 30 has a stepped portion 34 having multiple stepped portions 34a to 34c formed in a stepped shape, and a decorative portion 35 that is in close contact with the stepped portion 34. The stepped portions 34a to 34c protrude more as they move away from the lighting units 60 and 70 so that they can reflect the light from the lighting units 60 and 70 when they are located within the illumination range IA, and the decorative portion 35 has reflective portions 35a and 35b that reflect the light from the lighting units 60 and 70 when they are located within the illumination range IA.

[0064] The resin member 30 has multiple stepped portions 34a to 34c that reflect light when positioned within the illumination range IA. In addition, the resin member 30 is provided so as to be displaceable relative to the lighting units 60 and 70. Refer to Figures 7B, 8A, and 8B as well. Depending on the position of the resin member 30 relative to the illumination range IA, the stepped portions 34a to 34c that reflect light change. In other words, depending on the position of the resin member 30 relative to the lighting units 60 and 70, the patterns and other elements visible to the viewer change. By changing the patterns and other elements visible to the viewer, the aesthetic appeal can be further enhanced. A lighting device 20 with a high aesthetic appeal can be provided.

[0065] Refer to Figure 9. Furthermore, the decorative portion 35 has reflective portions 35a and 35b that reflect light from the illumination portions 60 and 70 when positioned within the illumination range IA. This allows the viewer to perceive a pattern different from that of the stepped portions 34a to 34c (see Figure 7A). This further enhances the aesthetic appeal.

[0066] Refer to Figure 2. Secondly, assuming the first lighting device 20, it further has a first drive mechanism 40 which is connected to the resin member 30 and displaces the resin member 30 toward the illumination range IA, and the lighting units 60 and 70 have a first light source 61 which illuminates the decorative part 35 from one end and a second light source 62 which illuminates the decorative part 35 from the other end, and the reflective parts 35a and 35b have a first reflective part 35a which reflects light when illuminated by the first light source 61 and a second reflective part 35b which reflects light when illuminated by the second light source 62 and brings out a different pattern than when the first reflective part 35a reflects light.

[0067] The resin member 30 can be displaced more easily relative to the lighting units 60 and 70.

[0068] Refer to Figure 9. When the first light source 61 is irradiated onto the first reflective section 35a, and when the second light source 71 is irradiated onto the second reflective section 35b, different patterns can be made to be perceived by the viewer Mn. This enhances the aesthetic appeal.

[0069] Thirdly, assuming the second lighting device 20, the first drive mechanism 40 includes a first motor 41 that generates a rotational driving force when energized, gears 42, 44, and 45 that rotate when the first motor 41 is operating, and a rack section 46 that converts the rotational motion of the gears 42, 44, and 45 into linear motion and is connected to the resin member 30. This allows the resin member 30 to be moved to a more precise position.
