Summary of the Invention

Problems to be Solved by the Invention

[0004] <7-digit tag Since the technology of Patent Document 1 configures the light source unit separately from the lamp body, when the light source unit is attached to the lamp body, it is necessary to electrically connect to the electric wire of the power source provided on the lamp body side to supply power to the light emitting element., Therefore, a connector is provided on the light source unit, and when the light source unit is attached to the lamp body, a power source side connector connected to the electric wire on the lamp body side is manually coupled to the connector on the light source unit side for electrical connection.

[0005] In lighting fixtures with this configuration, assembling the fixture, particularly the light source section, requires two steps: connecting the connectors on the lamp body side and the light source unit side, and then attaching the light source unit to the lamp body. Of these steps, the latter, attaching the light source unit to the lamp body, can be relatively easily automated by robots or other means, provided the lamp body and light source unit are positioned correctly. However, the former step, connecting the connectors, is difficult to automate because the lamp body connector and the light source unit connector must be connected before attaching the light source unit. Therefore, this presents a challenge in fully automating the assembly of lighting fixtures.

[0006] The objective of the present invention is to provide a vehicle lighting fixture that enables the fully automated assembly of the light source unit in the lighting fixture. [Means for solving the problem]

[0007] The vehicle lighting device of the present invention comprises a light source base provided in a lamp housing and a light source unit that is detachable from the light source base, wherein the light source unit is equipped with a light source and, when mounted on the light source base, is electrically connected to a power supply system provided in the lamp housing. Furthermore, the light source base is supported by a connector electrically connected to the power supply system, and the light source unit is equipped with a contact land made of a conductive material electrically connected to the light source, wherein when the light source unit is mounted on the light source base, the connector and the contact land are electrically connected.

[0008] In this invention, the light source unit includes a light source substrate on which a light-emitting element is mounted, and contact lands are formed on the surface of the light source substrate. The connector includes a connector body and a plurality of contact terminals provided on the connector body, and the contact terminals are configured to make elastic contact with the contact lands and be electrically connected. For example, the light source unit is mounted on one side of the light source base, the connector is supported on the other side of the light source base, and the contact terminals are exposed on one side of the light source base through an opening window provided on the light source base.

[0009] Furthermore, in the present invention, it is preferable that the connector has a plurality of support recesses provided in the connector body, the light source base has a plurality of support pieces that engage with each of the plurality of support recesses, and the connector is supported in a predetermined position relative to the light source base by the engagement of the support recesses and the support pieces. In addition, it is preferable that the connector has a positioning boss that is inserted into a positioning hole provided in the light source substrate, and when this positioning boss is inserted into the positioning hole, the connector is positioned in the planar direction and thickness direction of the light source substrate. [Effects of the Invention]

[0010] According to the present invention, by simply attaching the light source unit to the light source base, the contact lands of the light source substrate can be electrically connected to the connector, and the power supply system on the lamp housing side can be electrically connected to the light source unit. Therefore, manual electrical connection with connectors is unnecessary when assembling the light source, enabling automation of the light source unit attachment process, and even full automation of the lamp assembly.

[0012] Next, embodiments of the present invention will be described with reference to the drawings. Figure 1 is a schematic front view of an embodiment in which the vehicle lamp of the present invention is applied to a composite front lamp (front combination lamp) FCL located on the right front of the body of an automobile CAR. The front lamp FCL has an illumination lamp LL, an indicator lamp DL, and a signal lamp SL arranged inside a lamp housing 100 that is fixedly supported on the vehicle body. In the following description, the front-rear direction refers to the front-rear direction of the front lamp FCL, and the up-down and left-right directions are based on the directions in Figure 1.

[0013] The illumination lamp LL consists of a single lamp unit and, when lit, emits white light, functioning as a headlamp that provides illumination with the required low-beam and high-beam light distribution. The indicator lamp DL is configured as a lamp unit with a light-emitting surface extending in a horizontal line above the illumination lamp LL, and is configured as a DRL (Daytime Running Lamp) that emits white light. Alternatively, it may be configured as a PL (Positioning Lamp) or CL (Clearance Lamp). The signal lamp SL is positioned towards the outer edge in the vehicle width direction and is configured as a TSL (Turn Signal Lamp) that flashes amber light.

[0014] Figure 2 is a schematic exploded perspective view of the front lamp FCL. The lamp housing 100 comprises a lamp body 101 with an opening facing from the front to the side of the vehicle, and a translucent outer lens 102 fitted to cover the opening of the lamp body 101. The outer lens 102, also called an outer cover, is made of a colorless translucent resin or the like, and is formed into a curved surface that follows the curved shape of the right front part of the automobile body. A lighting circuit 120 is arranged inside the lamp body 101, and the wires (wire harness) 121 connected to this lighting circuit 120 are electrically connected to the illumination lamp LL, signal lamp SL, and indicator lamp DL, respectively, by connectors 5L, 5S, and 5. These wires 121 together with the lighting circuit 120 constitute a power supply system that supplies power to the illumination lamp LL, signal lamp SL, and indicator lamp DL.

[0015] Inside the lamp housing 100, the above-described illumination lamp LL, display lamp DL, and signal lamp SL are arranged, and an extension 110 is provided to cover the gaps between the lamps and enhance the design of the front lamp FCL. Windows 112 and 113 for exposing the illumination lamp LL and the signal lamp SL are opened in the extension 110. Regarding the illumination lamp LL and the signal lamp SL, since they have little relation to the present invention, detailed description is omitted, but when the illumination lamp LL and the signal lamp SL are positioned and installed with respect to the lamp housing 100, they are automatically electrically connected to the corresponding connectors 5L and 5S.

[0016] On a portion extending in the left-right direction along the upper edge of the extension 110, the inner lens 2 constituting the display lamp DL is supported in an extended state, and this portion of the extension 110 also functions as a reflector 111 that reflects the light of the inner lens 2 forward. The inner lens 2 is composed of a light guide (light conductor) formed of an elongated light-transmitting member made of a transparent resin or the like extending in a substantially horizontal direction.

[0017] One end 21 of the inner lens 2 is configured as a light incident portion, and the other region along the length direction is configured as a light emitting surface portion 22. The light emitting surface portion 22 is a light emitting surface, and although not shown in the figure, a light distribution step (lens step) for diverging or diffusing the emitted light to obtain a required light distribution is formed. Also, on the rear surface of this light emitting surface portion 22, a required reflection step (lens step) is formed as a light reflecting surface, or a light reflecting film is formed. The inner lens 2 is formed in a shape with a design effect, here a tapered line type, in order to enhance the appearance of the display lamp DL when lit.

[0018] Figure 3 is a perspective view of one end of the inner lens 2 in the indicator lamp DL, i.e., the vicinity of the light incident portion 21. The indicator lamp DL is equipped with a light source unit 1 that incidents light onto the light incident portion 21 of the inner lens 2. By being equipped with this light source unit 1, the white light emitted and emitted from the light source unit 1 is incident onto the light incident portion 21 of the inner lens 2. The incident light is guided through the inner lens 2 toward the other end and emitted from the light-emitting surface portion 22 facing forward of the front lamp FCL, resulting in a light-emitting state and causing the indicator lamp DL to light up.

[0019] Figure 4A is a perspective view of the light source unit 1 from the rear. The light source unit 1 is configured as a light source base 3, which is part of the lamp body 101, specifically the part where the light incident portion 21 of the inner lens 2 is supported. A detachable light source unit 4 is provided on this light source base 3. Figure 4A shows the light source unit 4 mounted on the light source base 3, which is configured on the lamp body 101.

[0020] Figure 4B is a cross-sectional view along line BB in Figure 4A. Figure 5 is an exploded perspective view of the light source unit 1 with the light source unit 4 removed from the light source base 3, showing the internal configuration of the light source base 3 and the light source unit 4. As shown in Figures 4B and 5, the light source base 3 has a bottom wall 31 formed from a part of the rear wall of the lamp body 101, and a cylindrical sleeve wall 32 that protrudes rearward, surrounding this bottom wall 31. Multiple engagement holes 321 are provided in the sleeve wall 32 in the circumferential direction, in this case three locations, so that the light source unit 4 can be attached. A circular insertion hole 311 and an irregularly shaped opening window 312 pass through the bottom wall 31 of the light source base 3. The light incident portion 21 of the inner lens 2 is inserted into the insertion hole 311 facing rearward, and its end face is exposed inside the sleeve wall 32 as the light incident surface 211. A connector 5 is supported on the front side of the bottom wall 31 of the light source base 3, facing the opening window 312.

[0021] The light source unit 4 comprises a circular plate-shaped unit body 41 and a heat sink 42. Three hook-shaped engaging pieces 411 are erected on the circumferential direction of the unit body 41, facing forward. These engaging pieces 411 correspond to engaging holes 321 in the sleeve wall 32 of the light source base 3. By bringing the light source unit 4 into contact with the edge of the sleeve wall 32, the three engaging pieces 411 engage with the corresponding three engaging holes 321, and the light source unit 4 is integrally mounted to the light source base 3. The unit body 41 also supports a light source substrate 43, which will be described in detail later.

[0022] Figure 6 is a perspective view of a portion of the light source unit 2, viewed from the front at an oblique angle relative to the light source base 3. As described above, the light incident portion 21 of the inner lens 2 and the connector 5 are supported on the bottom wall 31 of the light source base 3. Multiple contact terminals 52 protrude from the connector body 51 of the connector 5. The connector 5 is configured as a pin-type connector, and each contact terminal 52 is made of a contact pin consisting of a spring pin that has a spring inserted and can expand and contract in the protruding direction, as shown in Figure 8 (details omitted). Each contact pin 52 is electrically connected to the power supply wires 121 of the power supply system arranged in the lamp body 101, as shown in Figure 2, and power is supplied from the lighting circuit 120.

[0023] Figure 7 is a perspective view of the connector 5 removed from the light source base 3. Referring to Figures 6 and 7 together, the connector body 51 is formed in a roughly rectangular plate shape, and four contact pins 52 are arranged linearly in the width direction (a direction perpendicular to the longitudinal direction) on one side of one end of the longitudinal side. The connector body 51 also has sleeve portions 511 that protrude in the width direction on both sides of the contact pins 52, and positioning bosses 54 are erected on one side of these sleeve portions 511, i.e., on the side where the contact pins 52 protrude. These positioning bosses 54 are configured as two-stage bosses, with the tip portion 541 having a smaller diameter than the base portion 542.

[0024] Furthermore, the connector body 51 has three rectangular support recesses 55 cut out on both sides in the width direction and on the other end face in the longitudinal direction. Correspondingly, hook-shaped support pieces 56 are erected on the front side of the bottom wall 31 of the light source base 3 at positions corresponding to the three support recesses 55 of the connector body 51. As a result, when the connector body 51 is pressed toward the bottom wall 31 with the three support recesses 55 of the connector body 51 positioned relative to the three support pieces 56, each support piece 56 engages with its corresponding support recess 55. Therefore, the connector body 51, i.e., the connector 5, is positioned in the planar and height directions of the bottom wall 31 by three-point support from the three support pieces 56. In the connector 5 supported in this way, the connector pins 52 and positioning bosses 54 are exposed to the rear side of the bottom wall 31 through the opening window 312 of the bottom wall 31.

[0025] As shown in Figures 6 and 7, in the light source unit 4, the light source substrate 43 is fixed to the front of the unit body 41 by screws 44. On the front of this light source substrate 43 are light-emitting elements, such as multiple (in this case, four) chip-type LEDs (light-emitting diodes) 45, which serve as the light source for the indicator lamp DL. When the light source unit 4 is mounted on the light source base 3, the light-emitting surfaces of these LEDs 45 are positioned to face the light incident surface 211 of the inner lens 2, which is supported by the light source base 3.

[0026] Furthermore, contact lands 46 made of conductive material, such as a conductive film, are formed in a required pattern shape on the front surface of the light source substrate 43 and are electrically connected to multiple LEDs 45. Each of the multiple contact lands 46 is provided corresponding to one of the multiple connector pins 52 of the connector 5 supported by the light source base 3. In addition, positioning holes 47 are opened on both sides of the light source substrate 43, sandwiching the contact lands 46 in the arrangement direction. These positioning holes 47 are provided in positions corresponding to the positioning bosses 54 of the connector 5, and the inner diameter of the positioning holes 47 is equal to the diameter of the tip 541 of the positioning bosses 54.

[0027] The heat sink 42 shown in Figure 4A is integrally formed with the unit body 41 and has multiple heat dissipation fins erected on the rear side of the unit body 41. This heat sink 42 is designed to dissipate the heat generated when the LED 45 emits light.

[0028] When assembling the front lamp FCL with the above configuration, the illumination lamp LL, signal lamp SL, and extension 110 are assembled inside the lamp body 101 shown in Figure 2, and the inner lens 2 of the indicator lamp DL is attached to the extension 110. At this time, as shown in Figure 3, the light incident portion 21 of the inner lens 2 is attached to the light source base 3 provided on the lamp body 101. In addition, the outer lens 102 is attached to the front opening of the lamp body 101. Furthermore, as shown in Figure 4A, the light source unit 4 is attached to the light source base 3 from the rear of the lamp body 101 to assemble the light source unit 1.

[0029] During the assembly of the light source unit 1, as shown in Figures 4B and 5, the unit body 41 of the light source unit 4 is brought into contact with the edge of the sleeve wall 32 of the light source base 3. This causes the three engaging pieces 411 of the light source unit 4 to engage with the three engaging holes 321 of the light source base 3, thereby integrally mounting the light source unit 4 to the light source base 3. The mounted light source unit 4 is positioned relative to the light source base 3 by the engagement of the three engaging pieces 411. Therefore, the LED 45 mounted on the light source substrate 43 of the mounted light source unit 4 has its light-emitting surface facing the light incident surface 211 of the inner lens 2 supported by the light source base 3. Furthermore, the contact land 46 formed on the light source substrate 43 is positioned opposite the contact pin 52 of the connector 5 supported by the light source base 3 through the opening window 312 and is in contact with each other.

[0030] Figure 8 is a cross-sectional view showing the relationship between the connector 5 and the light source substrate 43. By mounting the light source unit 4 onto the light source base 3, the contact land 46 comes into contact with the tip of the contact pin 52. Since the contact pin 52 is configured as a spring pin, a good electrical connection is made to the contact land 46 by its spring force.

[0031] Simultaneously, the tip 541 of the positioning boss 54 of the connector 5 is inserted into the positioning hole 47 of the light source substrate 43. Since the positioning boss 54 is configured as a two-stage boss with the tip 541 having a smaller diameter than the base end 542, the base end 542 abuts against the front surface of the light source substrate 43. As a result, the light source substrate 43 is positioned with high precision in both the surface direction and the thickness direction relative to the connector 5. Therefore, the contact pin 52 and the contact land 46 are positioned with high precision, and the contact land 46 is also positioned in a suitable position relative to the protruding direction of the contact pin 52, thereby improving the reliability of the electrical connection between the two.

[0032] Once the light source unit 1 is assembled in this manner, power from the power supply system (wires 121) inside the lamp housing 100 is transmitted from the contact pins 52 of the connector 5 to the contact land 46, and power is supplied from the light source substrate 43 to the LED 45. As a result, the LED 45 emits light, and the light emitted from its light-emitting surface is incident on the light incident surface 211 of the inner lens 2. As described above, the incident light is guided through the inner lens 2 toward the other end and emitted from the light-emitting surface 22 facing forward, resulting in a light-emitting state and lighting up the indicator lamp DL. Each LED 45 generates heat due to the emission of light, and this heat is transferred from the light source substrate 43 to the unit body 41, and further transferred to the heat sink 42, where it is dissipated to the outside of the lamp housing 100.

[0033] As described above, in the embodiment, the light source unit 1 can be positioned in a suitable location relative to the light incident surface 211 of the inner lens 2 simply by attaching the light source unit 4 to the light source base 3. Furthermore, by attaching the light source unit 4 to the light source base 3, the contact land 46 of the light source substrate 43 can be electrically connected to the connector 5, and the LED 45 can be electrically connected to the power supply system (wire 121) on the lamp body 101 side. Therefore, manual electrical connection at the connector 5 is not required when attaching the light source unit 4, and the attachment work of the light source unit 4 can be automated, i.e., fully automated assembly of the lamp using a robot or the like becomes possible.

[0034] Figures 9 and 10 are perspective views of modified versions of the light source unit 1, corresponding to Figures 5 and 6 of the embodiment. Equivalent parts are denoted by the same reference numerals as in the embodiment. This modified version differs from the embodiment in the configuration of mounting the light source unit 4 to the light source base 3 and the configuration of the connector 5A. Regarding the former mounting configuration, the sleeve wall 32 of the light source base 3 has bayonet grooves 322 formed at three locations in the circumferential direction, with L-shaped notches extending from the tip. On the other hand, the light source unit 4 has bayonet pieces 412 protruding at three locations around the circumference of the unit body 41. Since the configurations of these bayonet grooves 322 and bayonet pieces 412 are already known, a detailed explanation will be omitted, but by inserting the bayonet pieces 412 into the bayonet grooves 322 and then rotating the light source unit 4 by a small angle, the two are engaged and integrated.

[0035] The latter connector 5A is composed of a contact piece type connector instead of a pin type connector. That is, the connector body 51 has multiple conductive contact pieces 52A, which are elastic, such as metal pieces, arranged in parallel as contact terminals. When the connector 5A is supported on the light source base 3, these contact pieces 52A are arranged radially with respect to the center of the light source unit 4 to be mounted, that is, the center of rotation when the light source unit 4 is mounted on the light source base 3.

[0036] The connector 5A is supported by the light source base 3, and the structure for positioning it in the planar direction, such as the configuration of the support recess 55 and support piece 56 shown in Figure 7, is the same as in the embodiment. On the other hand, since the tip of the contact piece 52A of this connector 5A is elastically deformed in the thickness direction of the light source substrate 43, a positioning boss 54 for positioning in the thickness direction of the light source substrate 43, as in the embodiment, is not provided.

[0037] On the other hand, the multiple contact lands 46A formed on the light source substrate 43 of the light source unit 4 are formed in the shape of an arc of the required length, concentrically arranged at different radial positions with respect to the center of the light source unit 4. The radial position of each contact land 46A corresponds to the position of each contact piece 52A of the connector 5A. In this modified example, the positioning holes 47 of the embodiment are not formed on the light source substrate 43.

[0038] In this modified version, when attaching the light source unit 4 to the light source base 3, the bayonet piece 412 is positioned in the bayonet groove 322, the bayonet piece 412 is inserted into the bayonet groove 322, and then the light source unit 4 is rotated by the required angle in the circumferential direction. As a result, the bayonet piece 412 engages with the bayonet groove 322, and the light source unit 4 is attached to the light source base 3.

[0039] By mounting the light source unit 4 onto the light source base 3, the LED 45 is positioned opposite the light incident surface 211 of the inner lens 2, similar to the embodiment. In addition, the multiple contact lands 46A are positioned opposite the contact pieces 52A of the connector 5A, and the tip portions of the contact pieces 52A elastically contact the corresponding contact lands 46A to establish an electrical connection. Since the contact pieces 52A have elasticity in the thickness direction, their elastic deformation range is larger than that of the contact pins 52, ensuring a reliable electrical connection even if the light source unit 4 is slightly misaligned relative to the light source base 3 in the thickness direction of the light source substrate 43. Furthermore, since the contact lands 46A are arc-shaped, a suitable electrical connection is maintained even if the light source unit 4 is slightly misaligned in the rotational direction relative to the light source base 3 when the light source unit 4 is mounted on the light source base 3.

[0040] In the modified configuration, simply by attaching the light source unit 4 to the light source base 3, the LED 45 can be positioned appropriately relative to the inner lens 2, and the contact land 46A of the light source substrate 43 can be electrically connected to the connector 5A, thereby electrically connecting the LED 45 to the power supply system (wire 121) on the lamp body 101 side. Therefore, manual electrical connection at the connector 5A is not required when assembling the light source unit 1, enabling automation of the installation of the light source unit 4, and even full automation of the lamp assembly.

[0041] In the embodiments and modifications, the connectors 5 and 5A are supported on the light source base 3 by a plurality of support pieces 56. However, if the desired positioning accuracy can be obtained, the connectors may be supported on the light source base by fastening members such as screws or adhesives. Alternatively, an engaging piece may be provided on the connector side and supported by engaging it with an engaging hole provided on the light source base.

[0042] The connector may also be configured as an edge connector. That is, an elastic contact piece is formed inside the connector, and a contact land is formed at the edge of the light source substrate. The contact piece and the contact land are electrically connected to each other when the edge of the light source substrate is inserted into the connector.

[0043] In the embodiment, the light source unit is shown to be fixed by engagement between an engaging piece and an engaging hole, or by engagement between a bayonet piece and a bayonet groove. However, a fixing structure using fastening members such as screws may also be used.

[0044] In the embodiment, the invention is applied to a lamp equipped with an inner lens configured as a light guide, but the present invention can be similarly applied to any lamp equipped with a light source. That is, it can also be applied to lamps in which light emitted from an LED in the light source is illuminated by an optical system such as a lens. Furthermore, the present invention is not limited to the indicator lamp described in the embodiment, but can also be applied as a light source for an illumination lamp or a signal lamp.
