Figure 4 shows the main parts of the lamp according to embodiment 1, and in more detail, Figure 4(a) is a cross-sectional view showing the arrangement of the connector in the lamp, and Figure 4(b) is a bottom view showing the relationship between the connector and the light source board in the lamp. Figure 5 is a diagram explaining the connector according to embodiment 1, and in more detail, Figure 5(a) is a perspective view showing the arrangement of the connector in the lamp, Figure 5(b) is a perspective view from below of the connector, and Figure 5(c) is a perspective view from above of the connector.

The power supply board 42 of the power supply unit 40 and the light source board 31 of the light source unit 30 are electrically connected via a connector 50 attached to the power supply unit 40.

The connector 50 is made up of multiple conductive parts 51 formed using a metal material or the like, and a fixing part 56 to which the conductive parts 51 are inseparably insert molded using an electrically insulating resin material or the like. Insert molding is a molding technique for integrally molding metal and resin.

The fixing portion 56 of the connector 50 has a main body portion 560, and a protrusion portion 561 and a guide portion 563, both of which protrude from the main body portion 560.

The main body 560 is formed in a flat, approximately rectangular parallelepiped shape. A flange 562 is formed at at least the end of the main body 560 in the longitudinal direction. The flange 562 is integrally molded with the main body 560 and is a plate-shaped protruding portion that protrudes from the side of the main body 560. The flange 562 is formed along the end of the main body 560 on the side where the protruding portion 561 protrudes.

The conductive portion 51 has a first connection end 52 formed in a plate shape that is in electrical contact with the power supply portion 43 of the power supply board 42 and that is elastically deformable, and a second connection end 53 formed in a rod shape that is electrically connected to the power receiving portion 314 of the light source board 31. The first connection end 52 is a connection end with the power supply portion 40, and the second connection end 53 is a connection end with the light source portion 30.

The first connection end 52 is arranged on the main body 560 so as to be exposed from an opening formed on the side of the main body 560 from which the protrusion 561 protrudes. When the connector 50 is attached to the power supply board 42, the first connection end 52 exposed from the main body 560 is arranged at a position overlapping the power supply unit 43 of the power supply board 42 and comes into contact with the power supply unit 43. Therefore, the first connection end 52 is electrically connected to the power supply unit 43 when the connector 50 is arranged on the power supply board 42. In other words, the first connection end 52 is electrically connected to the power supply unit 40 when the connector 50 is arranged on the power supply board 42.

The protruding portion 561 is formed in a cylindrical shape, including a part of the conductive portion 51. The protruding portion 561 is molded integrally with the main body portion 560. The second connection end 53 protrudes from the tip of the protruding portion 561. In other words, the second connection end 53 of the connector 50 is exposed at the tip of the protruding portion 561. Therefore, when the connector 50 is placed on the power supply board 42, the second connection end 53 protruding from the tip of the protruding portion 561 is inserted into the board through hole 312 provided in the light source board 31. The second connection end 53 is electrically connected to the light source unit 30 by connecting using a connection method such as soldering. The conductive portion 51 is reinforced by the protruding portion 561, and the conductive portion 51 is electrically insulated by the protruding portion 561.

The guide portion 563 is formed integrally with the main body portion 560, and is formed in a cylindrical shape so as to protrude in the same direction as the protrusion portion 561 from the flange portion 562 side of the main body portion 560. The guide portion 563 guides the light source substrate 31, which is placed in the placement portion 330 of the base 33, to a predetermined position in order to align the second connection end portion 53 of the conductive portion 51 with the substrate through hole 312.

The power supply unit 40 has a power supply board 42 housed in a power supply housing 41. The power supply board 42 is provided with a power supply circuit (not shown) for supplying power to the light emitting element 32 of the light source unit 30. The power supply circuit has a plurality of circuit components (not shown), and the circuit components are mounted on the power supply board 42.

The power supply board 42 also includes a power supply section 43 for outputting the lighting power generated by the power supply circuit. The power supply section 43 is an output end of the power supply circuit. In the first embodiment, the power supply section 43 is configured using a metal wire that can be mounted on the power supply board 42. The metal wire is also called a jumper wire. The power supply section 43 may be formed of a metal plate that can be mounted on the power supply board 42, or a conductive layer containing metal formed on the power supply board 42. The power supply section has a first power supply section 430 and a second power supply section 431, and is a pair of output ends. The power supply section 43 is preferably configured of an elastic material so as to absorb expansion and contraction due to changes in the temperature of the environment in which the lighting device 1 is used, or variations in assembly. The power supply section 43 is electrically connected to the conductive section 51 of the connector 50.

The power supply board 42 is formed with a board first insertion portion 421, which is a through hole for inserting the conductive portion 51 of the connector 50. The conductive portion 51 of the connector 50 is covered with a protrusion 561 formed of an insulating material, and the board first insertion portion 421 corresponds to the protrusion 561. In the first embodiment, the power supply board 42 is formed with two board first insertion portions 421, which are through holes with a substantially circular cross section. The board first insertion portion 421 may be formed in other shapes as long as it is formed so that the connector 50 can be inserted therethrough. For example, the board first insertion portion 421 may be formed as a single through hole with an elliptical cross section by connecting two holes in order to suppress variation between the two board first insertion portions 421. The board first insertion portion 421 may also be formed as a notch at the end of the power supply board 42 in the short direction Y.

The power supply board 42 has two board second insertion portions 422 formed to allow the guide portion 563 of the connector 50 to pass through. One board second insertion portion 422 may be formed, or three or more board second insertion portions 422 may be formed. In addition, the board second insertion portions 422 may be formed as notches at the ends of the power supply board 42 in the short direction Y.

In embodiment 1, the first substrate insertion portion 421 and the second substrate insertion portion 422 constitute the substrate insertion portion 420.

The housing body 410 of the power supply housing 41 has a housing insertion portion which is a through hole. In detail, the housing body 410 of the power supply housing 41 has a first board insertion portion 421 formed on the power supply board 42, a protrusion insertion hole 337 formed on the base 33, and a first housing insertion portion 414 which is connected to the board through hole 312 formed on the light source board 31, and a second board insertion portion 422 formed on the power supply board 42 and a second housing insertion portion 415 which is connected to the guide insertion hole 338 formed on the base 33.

The lighting fixture 3 is arranged such that the power supply board 42, the base 33 which is a pedestal, and the light source board 31 are connected so that the board first insertion portion 421, the protrusion insertion hole 337, and the board through hole 312 are connected. In other words, the lighting fixture 3 is arranged such that the power supply board 42 and the light source board 31 are connected so that the board first insertion portion 421 and the board through hole 312 are connected.

In addition, the lighting fixture 3 is arranged such that the power supply board 42, the base 33 which is a pedestal, and the light source board 31 are connected to the board second insertion portion 422, the guide portion insertion hole 338, and the end of the light source board 31 in the short-side direction Y. That is, the lighting fixture 3 is arranged such that the power supply board 42 and the light source board 31 are connected to the board second insertion portion 422 and the end of the light source board 31 in the short-side direction Y.

The protrusion 561 is inserted through the first board insertion portion 421, the first housing insertion portion 414, and the protrusion insertion hole 337 in that order from the mounting surface side of the power supply board 42 so that the tip of the protrusion 561 abuts or is close to the back surface of the light source board 31.

At this time, the conductive portion 51 insert molded in the main body portion 560 is inserted into each through hole so that the tip portion protrudes toward one surface (mounting surface) 310 of the light source substrate 31. Specifically, the conductive portion 51 is inserted from the mounting surface side of the power source substrate 42 through the substrate first insertion portion 421a, the housing first insertion portion 414, the protruding portion insertion hole 337, and the substrate through hole 312 in this order. In the lighting device 3, the conductive portion 51 is inserted from the power source portion 40 side toward the light source portion 30 side. The tip portion of the conductive portion 51 exposed from the protruding portion 561 is electrically connected to the power receiving portion 314 using a connection method such as soldering.

The light source board 31 is placed on the first surface 3300 of the placement section 330 of the base 33 with the conductive part 51 of the connector 50 attached to the power supply board 42 inserted through the protrusion insertion hole 337 formed in the base 33. At this time, the guide part 563 of the connector 50, which is inserted through the guide part insertion hole 338 formed in the base 33 and placed on the first surface 3300 of the placement section 330 of the base 33, guides the power supply board 42.

The electrical connection between the second connection end 521 of the conductive part 51 and the light source board 31 may be made by providing a connection part such as a terminal on the power receiving part and inserting or crimping the second connection end 521 of the conductive part 51 into the terminal.

The connector 50 in the lighting device 1 is electrically connected to the power supply unit 43 of the power supply unit 40 and the power receiving unit 314 of the light source unit 30 while being inserted into the through holes formed in the power supply board 42, the power supply housing 41, the base 33, and the light source board 31. In other words, the connector 50 electrically connects the power supply unit 43 of the power supply unit 40 and the power receiving unit 314 of the light source unit 30.

The connector 50 is fixed to the power supply housing 41 and electrically connected to the power supply unit 43 by the connector fixing portion 412 of the power supply housing 41 engaging with the flange portion 562 while undergoing elastic deformation. Because the flange portion 562 of the connector 50 is caught on the connector fixing portion 412, the connector 50 will not come off the power supply housing 41 unless the connector fixing portion 412 is intentionally deformed.
The flange portion 562 is hooked onto the connector fixing portion 412, and thereby functions as a retainer for the connector 50 in the insertion direction of the connector 50. In other words, the connector 50 engages with the power supply housing 41 while being placed on the power supply board 42, and is fixed to the power supply housing 41.

The lighting device 1 and the lamp 3 according to the first embodiment can electrically connect the power supply unit 40 and the light source unit 30 using the above-mentioned connector 50, so there is no need to use electric wires. By disposing the connector 50 on the power supply unit 40, the power supply unit 40 and the light source unit 30 can be electrically connected by a simple assembly process.

The connector 50 also includes a guide portion 563. Therefore, the light source board 31 placed on the placement portion 330 of the base 33 is guided to a predetermined position so that the second connection end 53 of the conductive portion 51 in the connector 50 fixed to the power supply unit 40 can be easily aligned with the board through hole 312. In other words, the positions of the power supply board 42 and the light source board 31 in the Y direction can be easily aligned by the assembly work.

By aligning the positions of the power supply board 42 and the light source board 31, no stress is applied to the electrical connection parts with the connector 50, such as the power supply part 43 and the first connection end 52, or the power receiving part 314 and the second connection end 53. This allows the quality of the electrical connection parts to be maintained for a long period of time.

In the first embodiment, the connector 50 has two guide portions 563 corresponding to the ends of the light source substrate 31 in the Y direction, but it may have one guide portion 563 corresponding to either one of the ends in the Y direction. It may also have multiple guide portions 563 corresponding to one end in the Y direction.
