h1 <h2 + h3 + h4 (1)
It is desirable to satisfy the equation (1). By setting the dimensions to satisfy the formula (1), when the wiring board 3 and the support part 4 are fixed by the screwing mechanism 51, the dimensions are arranged between the wiring board 3 and the support part 4. The light emitting module 2 is clamped, and a force for clamping acts between the light emitting module side connection terminal 23 of the light emitting module 2 and the wiring board side connection terminal 31 of the wiring board 3, so that the light emitting module side connection is performed. The terminal 23 and the wiring board side connection terminal 31 are reliably mechanically and electrically connected.

  As described above, the light emitting module 2 does not include a mechanism for attaching to the support portion 4 as a configuration of the light emitting module 2 itself, and when the wiring board 3 is attached to the support portion 4, Since the light emitting module 2 is disposed between the wiring board 3 and the support part 4 in advance, the wiring board 3 is attached to the support part 4 and at the same time, the wiring board 3 and the support part. In this configuration, attachment is performed in such a manner as to be clamped between the four.

  For example, if there is a place where the contact between the light emitting module side connection terminal 23 of the light emitting module 2 and the wiring board side connection terminal 31 of the wiring board 3 is weak and electrical connection is not reliable, the nearest screwing is performed. By strengthening the screwing of the mechanism 51, the force for pinching the light emitting module 2 in the vicinity of the screwing mechanism 51 is increased, and the force for partially pinching is increased, whereby the wiring board 3 is bent, The contact between the light emitting module side connection terminal 23 of the light emitting module 2 and the wiring board side connection terminal 31 of the wiring board 3 can be further strengthened.

  As described above, since the light emitting module 2 and the wiring board 3 are attached to the support portion 4 that is an attachment body, the light emitting module 2 and the wiring board 3 are brought into contact with each other to be electrically connected. After the module 2 and the wiring board 3 are attached, a separate work process for electrical connection becomes unnecessary, and the total number of assembly work processes is reduced.

As in 410, the shape and size of the light source substrate 21 may be taken along the outer shape. Since the support wall 410 is in thermal contact with the four side surfaces of the light source substrate 21 of the light emitting module 2, the contact area with the support portion 4 that is also a heat dissipation portion is increased, and the heat dissipation performance can be improved. In addition, in this specification, the said heat contact refers to the contact of the grade which heat conduction is fully performed, and the whole surface to contact does not necessarily need to be in contact.

  5A and 5B is effective particularly when the light emitting module 2 and the wiring board 3 are in contact with each other at a plurality of points. That is, there is a possibility that the size of the connection terminal and the thickness of the light source board 21 and the wiring board 3 of the light emitting module 2 may vary, but each wiring-side spring connection terminal 310 has flexibility, By bending according to the inter-terminal distance, electrical connection is realized between the wiring board side connection terminal 310 and the light emitting module side connection terminal 23 even if the inter-terminal distance varies.

  The spring structure may use a push spring or a tension spring using a coil spring (spring) in addition to the plate spring. The spring structure may be provided not on the wiring board side connection terminal 310 side of the wiring board 3 but on the light emitting module side connection terminal 23 side of the light emitting module 2, or on the wiring board side connection terminal 310 and the light emitting module side connection terminal 23.

  In the light source device 1C of the present invention, as in the third embodiment, the light emitting module 2 provided with the light emitting unit 22 and the light emitting module side connection terminal 23 on one surface of the light source substrate 21, and the light emitting module 2 is powered. A wiring board 300 having wirings to be supplied, a support portion 4 that is an attached body that supports the light emitting module 2 and attaches the wiring board 300, a reflection plate 61 and a transmission plate 62 as optical members, and an exterior body An instrument case 71 is further provided. The support 4 and the transmission plate 62 also serve as a part of the exterior body.

  Further, the wiring board 300 has a built-in constant current power supply circuit that converts an externally supplied power into a constant current to drive the light emitting module 2 provided on the wiring board 300. 37.

  In the above configuration, the circuit unit 37 includes circuit components such as a resistor 37a, a capacitor 37b, a coil 37c, and an FET 37d.

  It should be noted that a circuit component having a large calorific value, such as the FET 37d, is preferably disposed in the vicinity of the instrument case 71 which is an exterior body. By disposing a circuit component having a large calorific value in the vicinity of the exterior body, it is possible to prevent heat generated from the circuit component from being transmitted to the instrument case 71 that is the exterior body at an early stage and to accumulate heat inside the light source device. . Thus, the instrument case 71 which is an exterior body functions as a heat radiating section for releasing heat of the light emitting module 2 and the heat generating circuit component to the outside together with the support section 4 also serving as a part of the exterior body. Yes.

  Further, since the light emitting module 2 is a circuit component having a large calorific value like the FET 37d, the interval between a plurality of circuit components having a large calorific value and the interval between the circuit component having a large calorific value and the light emitting module 2 are driven. It is desirable to arrange them apart from each other so that the temperature gradient of the entire wiring board 300 or the entire light source device 1C becomes gentle. When the temperature gradient of the driving wiring board 300 or the entire light source device 1C becomes gentle, heat from the circuit components and the light emitting module 2 is locally accumulated and reaches a high temperature, and the circuit components and the light emitting module 2 are damaged. Can be prevented.

  Further, when the instrument case 71 is made of a material such as a metal or ceramic having high thermal conductivity and has a heat dissipation property, a circuit component having a large amount of generated heat is required to be in thermal contact with the instrument case 71. 300 may be provided. Since the instrument case 71 has heat dissipation and is in thermal contact with a circuit component that generates a large amount of heat, the heat of the circuit component is quickly transmitted to the instrument case 71 and is transmitted to the instrument case 71. Since the generated heat is released to the outside, efficient heat dissipation is possible.

  As described above, a power supply unit for converting a commercial AC power source into a constant current by providing a circuit component 37 having a constant current power source circuit for supplying a constant current for driving the light emitting module 2 inside the light source device 1C. It is not necessary to provide a separate light source, so that the introduction cost of the entire apparatus can be reduced, and the work burden when constructing the light source device can be reduced.

  Furthermore, you may have the wiring board 30 at the time of providing the light emitting module 2 demonstrated in Embodiment 2 in multiple numbers.
