Moreover, the lighting device 3 is attached to the back side of the component mounting wall 11b. In addition, the terminal block 7 (see FIGS. 4 and 7) is attached to the back side of the component mounting wall 11b. Therefore, electrical components are attached to both the front side and the back side of the component mounting wall 11b. Further, necessary electrical wiring processing for the light source unit 2 and the lighting device 3 is performed.

In this case, the case body 1 is a divided case of the base case 11 and the cover case 12. That is, the case body 1 is divided into two parts along the longitudinal direction into the base case 11 and the cover case 12, so that mounting and assembling of electrical components can be performed in this divided state. Thus, workability can be improved.
Further, since electrical components can be centrally mounted and arranged on the base case 11 side, workability is also improved in this respect.

  Further, the base case 11 is formed with an attachment support portion 11c attached to the attachment member F. Since the electrical components are concentrated and arranged on the base case 11 side, the base case 11 side is heavier in weight. However, since the base case 11 side is attached to the attachment member F, the attachment member F and the attachment support are attached. An excessive load can be suppressed from being applied to the portion 11c, and the lighting fixture can be stably supported. In addition, since the mounting support portion 11c is provided corresponding to the component mounting wall 11b in which the light source unit 2 and the lighting device are disposed, torque applied to the mounting support portion 11c is reduced using the mounting support portion 11c as a fulcrum. Furthermore, it is possible to reduce the stress on the joint portion between the base case 11 and the cover case 12, and it is easy to maintain waterproofness.

  When power is supplied to the lighting device 3 in the installation state of the lighting fixture, the light emitting elements 22 are energized through the substrate 21 and the light emitting elements 22 are turned on. The light emitted from the light emitting element 22 is collected through the lens member 23 and is transmitted through the front cover 4 and irradiated in the target direction.

Further, the heat generated from each light emitting element 22 is conducted from the back side of the substrate 21 to the component mounting wall 11b, further conducted from the side wall 11a to the cover case 12, and conducted to the entire case body 1 to be radiated. Therefore, the temperature rise of the light emitting element 22 can be suppressed, and the influence on the characteristics and life of the light emitting element 22 can be reduced. Similarly, the heat generated from the lighting device 3 is conducted to the component mounting wall 11b, and is conducted from the side wall 11a to the cover case 12 and further to the entire case body 1 to be radiated.
In this way, heat is conducted from both the front side and the back side of the component mounting wall 11b, so that effective heat dissipation can be realized.

  As described above, according to the present embodiment, the case body 1 is constituted by the divided case of the base case 11 and the cover case 12, so that the assembly workability is good and the productivity can be improved. Further, since the clearance C is formed between the extended end of the component mounting wall 11b and the inner surface of the cover case 12, it is possible to arrange a wiring connecting member such as a lead wire in the clearance C. Become.

  Furthermore, since the attachment support part 11c attached to the attachment member F is formed in the base case 11 side, a lighting fixture can be supported stably. Moreover, the sealing effect of the sealing member 5 can be enhanced by the joint strengthening means 6, and the waterproofness can be reliably ensured.

  Furthermore, since the terminal block 7 is disposed so as to be exposed in the state where the lid member 8 is removed, an effect of facilitating connection work of the power supply line can be achieved.
