An example of a work procedure for assembling the lighting device L will be described.

The light source unit 30 is attached to the housing 41. Specifically, the light source unit 30 is fitted between the pair of ribs 59 of the casing 41 with the light emitting surface facing up. This determines the position of the light source unit 30 in the left-right direction with respect to the housing 41. The holding member 54 is attached to the housing 41. The holding member 54 restricts the light source unit 30 from detaching from the housing 41 .

An upper cap 61 and a lower cap 62 are attached to both upper and lower ends of the case 40. The upper insertion portion 64 is located above the light source unit 30. A distal end surface 67 of the lower insertion portion 66 faces a lower end surface of the light source unit 30. A back surface 68R of the protruding portion 68 of the lower insertion portion 66 faces the front surface of the light source unit 30.

With the above steps, the work of assembling the lighting device L is completed. When the lighting device L is attached to the bathroom unit 10, the lower end surface of the light source unit 30 comes into contact with the distal end surface 67 of the lower insertion portion 66. Thereby, the light source unit 30 is supported by the lower insertion portion 66.

The operation and effects of the lighting device L configured as described above will be explained.

The lighting device L includes a case 40 in which the light source unit 30 is housed, and upper and lower caps 61 and 62 that close openings formed at both ends of the case 40 in the axial direction. The case 40 has a cylindrical shape that is long in one direction. The upper and lower caps 61 and 62 have an upper insertion part 64 and a lower insertion part 66 that are inserted into the case 40 from the opening. Between the outer surfaces of the upper and lower insertion sections 64 and 66 and the inner surface of the transparent cover 42, upper and lower water stop members 70U and 70S that are in close contact with the outer surfaces of the upper and lower insertion sections 64 and 66 and the inner surface of the transparent cover 42 are provided. It is equipped. The case 40, which is long in one direction, has a large amount of expansion and contraction in the axial direction due to thermal expansion and contraction. According to the lighting device L, even if the case 40, which is long in one direction, contracts in the axial direction, the upper and lower water stop members 70U and 70S are housed inside the case 40, so water stop properties can be ensured. Since the upper and lower water stop members 70U and 70S are housed inside the case 40, no step is formed on the outer surface of the case 40. Therefore, the appearance of the lighting device L can be improved.

In the lighting device L, the entire upper and lower water stop members 70U and 70S are located inside the case 40. A gap 73 is formed at the end of the case 40 in the axial direction between the outer surfaces of the upper and lower insertion portions 64 and 66 and the inner surface of the transparent cover 42 . According to this configuration, even if the translucent cover 42, which is long in one direction, expands and contracts in the axial direction, the upper and lower water stop members 70U and 70S do not protrude outward from the translucent cover 42, so that the water stop property is more reliably achieved. Can be secured. Since the gap 73 is formed at the lower end of the lighting device L, condensation generated inside the case 40 can be drained from the gap 73 at the lower end of the lighting device L.

In the illumination device L, an axial positioning section for determining the vertical position of the light source unit 30 is provided on the distal end surface 67 of the lower insertion section 66. According to this configuration, since the light source unit 30 is disposed above the lower insertion part 66 in the vertical direction of the case 40, even if water enters the inside of the case 40 from the opening at the lower end of the case 40, , making it difficult to reach the light source unit 30.

The case 40 of the lighting device L has a transparent cover 42 on the front side. A back surface 68R of the protrusion 68 that determines the position of the light source unit 30 in the front and back directions is provided on the distal end surface 67 of the lower insertion portion 66. According to this configuration, since the position of the light source unit 30 in the front and back directions is determined by the back surface 68R of the protrusion 68, the distance between the light source unit 30 and the light-transmitting cover 42 can be kept constant.
