Description

[Technical Field]

[0001] The present invention relates to an interior lamp for a vehicle. [Background technology]

[0002] Conventionally, a vehicle interior lamp includes a light source, a circuit board that supplies power to the light source, and a pair of conductive members that electrically connect the circuit board to a vehicle power source. The conductive member has a terminal portion that is inserted into a through hole in the circuit board, and the terminal portion is electrically connected to the light source via the wiring pattern of the circuit board. The following physical and electrical connection structures between the terminal portion and the circuit board are known. For example, Patent Document 1 listed below discloses a connection structure between a press-fit terminal and a circuit board. In this connection structure, an elastic portion of the press-fit terminal is elastically deformed while being inserted into the through hole, and a claw portion that protrudes from the through hole is hooked on the back side of the circuit board to prevent the press-fit terminal from coming out. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-172986 Summary of the Invention [Problem to be solved by the invention]

[0004] The press-fit terminal maintains its connection position in the through-hole due to the contact load between its elastic portion and the through-hole. Therefore, in a vehicle interior light, vibrations caused by road impacts or other factors are transmitted to the vehicle body during driving. Depending on the magnitude of the input load and contact load, the press-fit terminal may move in the insertion / removal direction relative to the through-hole. However, in this vehicle interior light, the claw portion prevents the press-fit terminal from being removed from the circuit board. However, because the press-fit terminal cannot be positioned in the insertion direction relative to the through-hole, it may be inserted further in. In this case, the contact load between the elastic portion of the press-fit terminal and the through-hole changes as the position of the press-fit terminal changes, potentially destabilizing the electrical conductivity between them.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a vehicle interior lamp that is capable of stabilizing electrical conductivity. [Means for solving the problem]

[0006] The present invention is characterized in that it comprises a light source, a circuit board that supplies power to the light source via a wiring pattern, a pair of conductive members that electrically connect a vehicle power source to the wiring pattern, a housing that houses the light source, the circuit board, and the conductive members, and a lens member that transmits light from the light source, wherein the conductive member has an electrical connection body that is inserted into a through hole serving as a contact insertion hole from a first plane side of the circuit board and brings a contact portion into contact with an electrical connection portion on the periphery of the contact insertion hole on a second plane side of the circuit board, an elastic pressing body that applies a reaction force due to elastic deformation to the first plane when the contact portion and the electrical connection portion are in contact, and clamps the circuit board between the contact portion and the first plane, and a main body that causes the electrical connection body and the elastic pressing body to protrude from their ends. [Effects of the Invention]

[0007] The vehicle interior light according to the present invention clamps the circuit board between the contact portion of the electrical connector and the elastic pressing body, improving the holding force of the conductive member relative to the circuit board and thereby suppressing misalignment of the conductive member relative to the circuit board. In this case, the contact portion of the electrical connector contacts the electrical connection portion of the circuit board, and the effect of suppressing misalignment of the conductive member relative to the circuit board allows the electrical connection portion and the contact portion to be kept in contact. Therefore, the vehicle interior light according to the present invention stabilizes the conductivity between the circuit board and the conductive member, thereby enabling a stable power supply to the light source.

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vehicle interior lamp according to the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention is not limited to this embodiment.

[0010] [Embodiment] One embodiment of a vehicle interior lamp according to the present invention will be described with reference to FIGS. 1 to 9. FIG.

[0011] Reference numeral 1 in Figures 1 to 6 indicates a vehicle interior light of this embodiment. This vehicle interior light 1 is installed inside the vehicle cabin. For example, the vehicle interior light 1 shown here is installed on the ceiling R inside the vehicle cabin (Figures 1 and 2).

[0012] The vehicle interior lamp 1 includes a light source 10 and a circuit board 20 that supplies power to the light source 10 (FIGS. 4 to 6).

[0013] Here, a light emitting diode is used as the light source 10. The circuit board 20 is a so-called printed circuit board, and has a wiring pattern (printed pattern) formed (printed) with a conductive material such as copper foil on an insulating layer made of an insulating material such as epoxy resin, glass epoxy resin, paper epoxy resin, or ceramic. The light source 10 is electrically connected to the power supply wiring pattern of the circuit board 20 by, for example, soldering. The circuit board 20 supplies power to the light source 10 via the wiring pattern.

[0014] The circuit board 20 is formed in a flat plate shape, and a wiring pattern is formed on at least one of one plane (hereinafter referred to as the "first plane") 20a and the other plane (hereinafter referred to as the "second plane") 20b (FIG. 7). The circuit board 20 shown here is formed in a rectangular flat plate shape.

[0015] The vehicle interior light 1 also includes a pair of conductive members 30 that electrically connect a vehicle power source (such as a secondary battery) to the power supply wiring pattern on the circuit board 20 (FIGS. 4 to 9). The conductive members 30 are press-formed using a metal plate as a base material. In the vehicle interior light 1 shown here, the conductive members 30 are formed as bus bars.

[0016] The conductive member 30 has an electrical connection body 31 that is inserted into a through-hole serving as the contact insertion hole 21 from the first flat surface 20a side of the circuit board 20 and that brings the contact portion 31a into contact with the electrical connection portion 22 on the periphery of the contact insertion hole 21 on the second flat surface 20b of the circuit board 20 (FIGS. 4 to 9). Furthermore, the conductive member 30 has an elastic pressing body 32 that applies a reaction force due to elastic deformation to the first flat surface 20a when the contact portion 31a and the electrical connection portion 22 are in contact with each other, and that holds the circuit board 20 between the first flat surface 20a and the contact portion 31a (FIGS. 4 to 9). The conductive member 30 is provided with one electrical connection body 31 and one elastic pressing body 32.

[0017] In the circuit board 20, a contact insertion hole 21 that connects the first plane 20a side and the second plane 20b side is formed for each conductive member 30. In this circuit board 20, two through holes are formed spaced apart from each other, and each of these through holes is used as a contact insertion hole 21. The electrical connection portion 22 is, for example, a part of the power supply wiring pattern on the second plane 20b of the circuit board 20. Furthermore, if the contact insertion hole 21 is a through-hole in the circuit board 20, the electrical connection portion 22 may be, for example, a land on the periphery of the contact insertion hole 21.

[0018] The conductive member 30 has a main body 33 from which the electrical connecting body 31 and the elastic pressing body 32 protrude (FIGS. 4 and 7 to 9). The main body 33 is formed in a flat plate shape. Here, two contact insertion holes 21 are formed in the circuit board 20, each having the same rectangular shape. Therefore, the inner circumferential surface of the contact insertion hole 21 is formed by two pairs of opposing wall surfaces that face each other. The main body 33 shown here is formed in a rectangular flat plate shape. In the conductive member 30, one side portion 33a of the main body 33 is arranged opposite the first plane 20a of the circuit board 20, and the electrical connecting body 31 protruding from the side portion (hereinafter referred to as the "opposing side portion") 33a of the main body 33 is inserted into the contact insertion hole 21 with the direction perpendicular to the plane of the main body 33 aligned with the direction in which one pair of opposing wall surfaces of the contact insertion hole 21 face each other (FIGS. 4 and 7). The electrical connector 31 protrudes from approximately the center of the opposing side 33 a of the main body 33 .

[0019] The electrical connection body 31 has a fixed end on the main body 33 side and a free end as a contact portion 31a, and is formed in a cantilever shape such that the free end side is elastically deformed by a force received from the inner peripheral surface of the contact insertion hole 21 of the circuit board 20. The electrical connection body 31 is formed in an axial shape having a shaft portion 31b to be inserted into the contact insertion hole 21, and a contact portion 31a that is provided at the tip of the shaft portion 31b protruding from the contact insertion hole 21 toward the second flat surface 20b of the circuit board 20 and is folded back on the second flat surface 20b side toward the second flat surface 20b (FIGS. 4 and 7 to 9).

[0020] The shank 31b is a portion that protrudes in an axial manner from the opposing side 33a of the flat plate-shaped main body 33 on the same plane as the main body 33, and its end on the main body 33 side serves as a fixed end of the electrical connecting body 31. The shank 31b is inclined toward one opposing wall surface (one of the other pair of opposing wall surfaces) on the inner circumferential surface of the contact insertion hole 21 with respect to the hole axis direction of the contact insertion hole 21.

[0021] The contact portion 31a is bent from the tip of the shaft portion 31b in a U-shape or a V-shape on the same plane as the main body 33, and is folded back toward the electrical connection portion 22 on the peripheral edge on one opposing wall surface (one of the other pair of opposing wall surfaces) of the inner circumferential surface of the contact insertion hole 21. In this contact portion 31a, the tip of the folded back portion becomes a contact point, and this contact point at the tip is brought into contact with the electrical connection portion 22.

[0022] The elastic pressing body 32 is pressed against the first flat surface 20a of the circuit board 20 with its contact portion 31a and electrical connection portion 22 in contact, causing elastic deformation. The elastic pressing body 32 is formed in a cantilever shape that protrudes in an axial direction from the electrical connecting body 31 at the opposing side portion 33a of the main body 33 toward the tilt direction of the shaft portion 31b. The elastic pressing body 32 shown here protrudes from a corner on the tilt direction side toward the tilt direction of the shaft portion 31b on the same plane as the main body 33, and is folded back midway in the same direction as the contact portion 31a of the electrical connecting body 31. The apex of the folded back elastic pressing body 32 serves as a contact point, and this contact point of the apex is pressed against the periphery of the first flat surface 20a of the circuit board 20 and against one of the opposing wall surfaces (one of the other pair of opposing wall surfaces) on the inner circumferential surface of the contact insertion hole 21, causing elastic deformation, for example, from the base on the fixed end side.

[0023] In this conductive member 30, when the electrical connecting body 31 is inserted into the contact insertion hole 21 with the contact portion 31a at the tip end first, the contact portion 31a receives force from one opposing wall surface (one of the other pair of opposing wall surfaces) on the inner circumferential surface of the contact insertion hole 21, causing the shank 31b to elastically deform. In this conductive member 30, the elastic pressing body 32 in contact with the first flat surface 20a of the circuit board 20 is pressed against the first flat surface 20a and elastically deformed, causing the contact portion 31a to come out of the contact insertion hole 21 toward the second flat surface 20b of the circuit board 20 and eliminating the elastic deformation of the shank 31b. Thereafter, in this conductive member 30, the pressing force of the elastic pressing body 32 against the first plane 20a of the circuit board 20 is released, so that the circuit board 20 is clamped between the contact portion 31a of the electrical connection body 31, which is in contact with the electrical connection portion 22 on the second plane 20b of the circuit board 20, and the elastic pressing body 32, while the reaction force caused by the elastic deformation of the elastic pressing body 32 is still acting on the first plane 20a.

[0024] The conductive member 30 has a terminal portion 34 that is physically and electrically connected to a mating connector (not shown) at the end of a wire harness connected to a vehicle power source (FIGS. 4 and 7 to 9). The terminal portion 34 is mated and connected to a mating terminal fitting (not shown) housed in a mating fitting portion of a mating housing. The terminal portion 34 is provided on a side portion 33b of the main body 33 opposite to the opposing side portion 33a. The terminal portion 34 shown here is a male terminal portion that protrudes axially from the side portion 33b.

[0025] The vehicle interior light 1 includes a housing 40 that houses a light source 10, a circuit board 20, and a conductive member 30 (FIGS. 1 to 6). In the vehicle interior light 1, a pair of conductive members 30 are pre-assembled to the circuit board 20 on which the light source 10 is mounted, and the assembled body of these members is housed in the housing 40.

[0026] The casing 40 includes a housing member 40A and a cover member 40B molded from an insulating material such as synthetic resin (FIGS. 1 to 6).

[0027] The housing member 40A has a housing main body 41 that supports the circuit board 20 with the light source 10 and the pair of conductive members 30, and a cylindrical fitting portion 42 that accommodates the terminal portions 34 of each conductive member 30 and into which the mating fitting portion of the mating housing is inserted and fitted together with the mating terminal fittings (Figures 1 to 6).

[0028] The cover member 40B has a surrounding wall portion 43 that surrounds the contact insertion hole 21 side of the circuit board 20 supported by the housing main body 41 and the pair of conductive members 30, and a square cylindrical wall portion 44 that surrounds the light source 10 side of the circuit board 20 that protrudes from the surrounding wall portion 43 (FIGS. 1, 2, and 4 to 6). The light source 10 protrudes from an opening 44a of the cylindrical wall portion 44 (FIG. 4).

[0029] The housing member 40A and the cover member 40B are assembled together, and the assembled state is maintained by the first cover holding portion 45 of the housing member 40A and the second cover holding portion 46 of the cover member 40B (FIGS. 1, 2, 5, and 6). Here, four pairs of first cover holding portion 45 and second cover holding portion 46 are provided.

[0030] The first cover holding portion 45 is a flexible piece having a through hole 45a formed therein and protruding from the housing main body 41. The second cover holding portion 46 is a claw-like protruding portion that protrudes from the outer wall surface of the surrounding wall portion 43. The second cover holding portion 46 is inserted into the through hole 45a of the first cover holding portion 45 when the housing member 40A and the cover member 40B are in a fully assembled state. The second cover holding portion 46 is engaged with the periphery of the through hole 45a in the first cover holding portion 45 when the fully assembled housing member 40A and the cover member 40B are about to be pulled apart. This maintains the fully assembled state of the housing member 40A and the cover member 40B.

[0031] The vehicle interior lamp 1 includes a lens member 50 that transmits light from the light source 10 (FIGS. 1 to 6).

[0032] The lens member 50 is formed into a box shape (FIGS. 1 to 6) by a rectangular, flat light-transmitting portion 51 and a square cylindrical peripheral wall portion 52 that hangs down from the peripheral edge of the light-transmitting portion 51. The vehicle interior lamp 1 is embedded in the ceiling R with the light-transmitting portion 51 of the lens member 50 exposed.

[0033] The lens member 50 is assembled to the cover member 40B by inserting the peripheral wall portion 52 into the cylindrical wall portion 44 of the cover member 40B through the opening 44a. The cover member 40B and the lens member 50 are maintained in their assembled state by the first lens holding portion 47 of the cover member 40B and the second lens holding portion 53 of the lens member 50 (FIGS. 1, 2, 5, and 6). Here, four pairs of first lens holding portions 47 and second lens holding portions 53 are provided.

[0034] The first lens holding portion 47 is a flexible piece having a through hole 47a formed therein, and is formed as a part of the cylindrical wall portion 44. The second lens holding portion 53 is a claw-like protruding portion that protrudes from the outer wall surface of the peripheral wall portion 52. The second lens holding portion 53 is inserted into the through hole 47a of the first lens holding portion 47 when the cover member 40B and the lens member 50 are in an assembled state. The second lens holding portion 53 is engaged with the peripheral edge of the through hole 47a of the first lens holding portion 47 when the cover member 40B and the lens member 50 are to be pulled apart after the assembled state. This maintains the cover member 40B and the lens member 50 in their assembled state.

[0035] In this vehicle interior light 1, a capacitance type switch is used as the switch for turning on and off the light source 10. Therefore, this vehicle interior light 1 is provided with a switch bus bar 60 that serves as an electrode of the capacitance type switch (FIGS. 4 to 6). This switch bus bar 60 is formed from a metal material and is housed in a box of the lens member 50.

[0036] The switch bus bar 60 has a rectangular annular bus bar main body 61 that is in close contact with the periphery of the light transmitting portion 51 inside the box of the lens member 50 (FIGS. 4 to 6). The switch bus bar 60 also has a first electrical connection body 62 that protrudes from the bus bar main body 61 and whose protruding tip contacts a first electrical connection portion 23 on the first plane 20a of the circuit board 20, and a second electrical connection body 63 that protrudes from the bus bar main body 61 and whose protruding tip contacts a second electrical connection portion 24 on the second plane 20b of the circuit board 20 (FIGS. 4 to 7). The first electrical connection portion 23 is part of the wiring pattern for the switch on the first plane 20a of the circuit board 20. The second electrical connection portion 24 is part of the wiring pattern for the switch on the second plane 20b of the circuit board 20.

[0037] The switch bus bar 60 changes its capacitance when an operator brings a finger close to the light-transmitting portion 51 of the lens member 50 or touches the light-transmitting portion 51 with a finger. The circuit board 20 turns the light source 10 on or off by detecting the change in capacitance of the switch bus bar 60 via the first electrical connection portion 23 and the second electrical connection portion 24.

[0038] The vehicle interior lamp 1 includes a rectangular annular bezel member 70 that surrounds the periphery of the light transmitting portion 51 inside the vehicle cabin (FIGS. 1 to 6).

[0039] As described above, the vehicle interior light 1 of this embodiment sandwiches the circuit board 20 between the contact portion 31a of the electrical connecting body 31 and the elastic pressing body 32, improving the holding force of the conductive member 30 relative to the circuit board 20 and thereby suppressing misalignment of the conductive member 30 relative to the circuit board 20. In this state, in the vehicle interior light 1, the contact portion 31a of the electrical connecting body 31 is in contact with the electrical connection portion 22 of the circuit board 20, and the effect of suppressing misalignment of the conductive member 30 relative to the circuit board 20 makes it possible to maintain contact between the electrical connection portion 22 and the contact portion 31a. Therefore, the vehicle interior light 1 of this embodiment can stabilize the conductivity between the circuit board 20 and the conductive member 30, thereby enabling a stable supply of power to the light source 10.

[0040] [Variations] 10 and 11 designates a vehicle interior light of this modified example. The vehicle interior light 2 of this modified example is obtained by replacing the circuit board 20 and conductive member 30 in the vehicle interior light 1 of the above-described embodiment with a circuit board 120 and conductive member 130 described below. Therefore, in this modified example, the same members and parts as those shown in the embodiment are denoted by the same reference numerals as in the embodiment, and their description will be omitted.

[0041] The circuit board 120 of this modified example is a circuit board 20 with a light source 10 of the embodiment, in which the pair of contact insertion holes 21 and the pair of electrical connection portions 22 of the embodiment are replaced with a pair of contact insertion holes 121 and a pair of electrical connection portions 122 described below in accordance with the change in the conductive member 130 described below (Figures 11 and 12).

[0042] The contact insertion hole 121 of this modified example is obtained by changing the size and position of the contact insertion hole 21 in the circuit board 20 of the embodiment, and, like the contact insertion hole 21, is formed as a rectangular through-hole that communicates between the first flat surface 120a side and the second flat surface 120b side of the circuit board 120 (FIGS. 11 and 12). The electrical connection portion 122 of this modified example may be part of the power supply wiring pattern on the second flat surface 120b of the circuit board 120, like the electrical connection portion 22 of the embodiment, or may be a land on the periphery of the contact insertion hole 121 if the contact insertion hole 121 is a through-hole in the circuit board 120.

[0043] The conductive member 130 of this modification is similar to the conductive member 30 of the embodiment in which the opposing side 33a of the main body 33 is modified, and has two pairs of electrical connecting bodies 131 and elastic pressing bodies 132, and a main body 133 (FIGS. 11 to 14). This conductive member 130 clamps the circuit board 120 for each combination of the electrical connecting bodies 131 and elastic pressing bodies 132. Here, for convenience, the electrical connecting bodies 131 and elastic pressing bodies 132 of one combination will be referred to as electrical connecting body 131A and elastic pressing body 132A, and the electrical connecting body 131 and elastic pressing body 132 of the other combination will be referred to as electrical connecting body 131B and elastic pressing body 132B.

[0044] The combination of one electrical connection body 131A and elastic pressing body 132A is equivalent to the electrical connection body 31 and elastic pressing body 32 provided in the conductive member 30 of the embodiment. Therefore, the electrical connection body 131A has a contact portion 131a and a shaft portion 131b similar to the electrical connection body 31 of the embodiment (FIGS. 11 to 14). Therefore, the shaft portion 131b is a portion that protrudes in an axial shape from an opposing side portion 133a of the flat plate-shaped main body 133 on the same plane as the main body 133, and is inclined toward one opposing wall surface (one of the other pair of opposing wall surfaces) on the inner circumferential surface of the contact insertion hole 121 with respect to the hole axis direction of the contact insertion hole 121. The contact portion 131a is bent from the tip of the shaft portion 131b in a U-shape or V-shape on the same plane as the main body 133, and is folded back toward the electrical connection portion 122 on the peripheral edge on the opposing wall surface (one of the other pair of opposing wall surfaces). In addition, the elastic pressing body 132A protrudes from the corner of the opposing side 133a of the main body 133 on the tilting direction side of the shaft portion 131b toward the tilting direction side of the shaft portion 131b on the same plane as the main body 133, and is folded back in the same direction as the contact portion 131a of the electrical connecting body 131A along the way.

[0045] In contrast to this, in the conductive member 130 of this modified example, the other combination of the electrical connecting member 131B and the elastic pressing member 132B is configured as follows.

[0046] Like the electrical connecting body 131A, the electrical connecting body 131B has a contact portion 131c and a shaft portion 131d that perform the same functions as the contact portion 131a and the shaft portion 131b of the electrical connecting body 131A (FIGS. 11 to 14).

[0047] The shank 131d is a portion that protrudes in an axial shape from the opposing side 133a of the main body 133 on the same plane as the main body 133, and its end on the main body 133 side is used as a fixed end of the electrical connecting body 131. This shank 131d is inclined toward the other opposing wall surface (the other of the other pair of opposing wall surfaces) on the inner circumferential surface of the contact insertion hole 121 with respect to the hole axis direction of the contact insertion hole 121. In other words, this shank 131d is inclined in the opposite direction to the shank 131b of the electrical connecting body 131A.

[0048] The contact portion 131c is bent from the tip of the shaft portion 131d into a U or V shape on the same plane as the main body 133 and folded back toward the electrical connection portion 122 on the peripheral edge on the other opposing wall surface (the other of the other pair of opposing wall surfaces) side of the inner circumferential surface of the contact insertion hole 21. In this contact portion 131c, the tip of the folded back end becomes a contact point, and the contact point at this tip is brought into contact with the electrical connection portion 122.

[0049] The elastic pressing body 132B is formed in a cantilever shape that protrudes in an axial direction from the electrical connecting body 131B on the opposing side 133a of the main body 133 toward the tilt direction of the shaft 131d. The elastic pressing body 132B shown here protrudes from a corner on the tilt direction side toward the tilt direction of the shaft 131d on the same plane as the main body 133, and is folded back midway in the same direction as the contact portion 131c of the electrical connecting body 131B. In other words, the elastic pressing body 132B protrudes in the opposite direction to the elastic pressing body 132A. The vertex of the folded back portion serves as a contact point, and this contact point of the vertex is pressed against the periphery of the other opposing wall surface (the other of the other pair of opposing wall surfaces) on the first plane 120a of the circuit board 120 and on the inner circumferential surface of the contact insertion hole 121, thereby elastically deforming, for example, from the base on the fixed end side.

[0050] In the conductive member 130 of this modified example, the contact portion 131a of the electrical connecting body 131A is in contact with the electrical connecting portion 122 and the contact portion 131c of the electrical connecting body 131B is in contact with the electrical connecting portion 122, and the elastic pressing body 132A and the elastic pressing body 132B are pressed against the first plane 120a of the circuit board 120 to cause elastic deformation.

[0051] In this conductive member 130, when the electrical connection body 131A and the electrical connection body 131B are inserted into the contact insertion hole 121 from the contact portions 131a, 131c at their respective tips, the contact portion 131a receives a force from one opposing wall surface (one of the other pair of opposing wall surfaces) on the inner circumferential surface of the contact insertion hole 121, causing the shaft portion 131b to elastically deform, and the contact portion 131c receives a force from the other opposing wall surface (the other of the other pair of opposing wall surfaces) on the inner circumferential surface of the contact insertion hole 121, causing the shaft portion 131d to elastically deform. In this conductive member 130, the elastic pressing bodies 132A and 132B that are in contact with the first plane 120a of the circuit board 120 are elastically deformed while being pressed against the first plane 120a, causing the respective contact portions 131a and 131c to come out of the contact insertion holes 121 toward the second plane 120b of the circuit board 120, thereby eliminating the elastic deformation of the respective shaft portions 131b and 131d. Thereafter, in this conductive member 130, by releasing the pressing forces of elastic pressing body 132A and elastic pressing body 132B against first plane 120a of circuit board 120, each elastic pressing body 132A and elastic pressing body 132B applies a reaction force due to elastic deformation to first plane 120a, while clamping circuit board 120 between contact portion 131a of electrical connecting body 131A in contact with electrical connection portion 122 on second plane 120b of circuit board 120 and elastic pressing body 132A, and also clamping circuit board 120 between contact portion 131c of electrical connecting body 131B in contact with electrical connection portion 122 and elastic pressing body 132B.

[0052] As described above, the vehicle interior light 2 of this modified example clamps the circuit board 120 between two pairs of electrical connecting body 131 and elastic pressing body 132 (one combination of electrical connecting body 131A and elastic pressing body 132A, and the other combination of electrical connecting body 131B and elastic pressing body 132B), and can improve the holding force of the conductive member 130 relative to the circuit board 120 compared to the vehicle interior light 1 of the embodiment. Therefore, the vehicle interior light 2 of this modified example further reduces misalignment of the conductive member 130 relative to the circuit board 120 compared to the vehicle interior light 1 of the embodiment. Therefore, the vehicle interior light 2 of this modified example can further stabilize the conductivity between the circuit board 120 and the conductive member 130 compared to the vehicle interior light 1 of the embodiment, and can therefore provide a more stable power supply to the light source 10.
