  The reflector 12 includes a flat plate-like fixing portion 122 that is placed and fixed on the light source substrate 11, a reflecting portion 124 that is provided around the fixing portion 122, and a mounting flange 126 that is provided around the reflecting portion 124. And have.

The inner cover 13 is a part formed by, for example, integral molding, is made of a resin material having translucency (has a translucent region) , and has a substantially cylindrical shape. As shown in FIG. 5, the inside of the inner cover 13 is divided into two regions, a light emission region 13 </ b> A and a substrate placement region 13 </ b> B, by a partition plate 131, and the cross section of the inner cover 13 has a substantially H shape. In the drawing, the light emitting region 13A, which is the upper region, is mainly provided with the light source substrate 11 and the reflecting portion 124 of the reflector 12. For example, two circuit boards (a power supply board B1 and a control board B2 described later) are arranged in the board arrangement area 13B, which is the lower area.

  An upper opening 132 and a lower opening 133 are formed by opening the upper end of the light emitting region 13A of the inner cover 13 and the lower end of the substrate arrangement region 13B, respectively. An upper flange 134 is provided around the upper opening 132, and a plurality of protrusions 134 a are provided at predetermined angular positions around the z axis in the upper flange 134. As shown in FIG. 6, these protrusions 134 a engage with holes 126 a provided in the attachment flange 126, and the lower surface of the attachment flange 126 of the reflector 12 is placed on the upper surface of the upper flange 134 of the inner cover 13. The

  The macro shape of the reflecting portion 124 (the reflecting surface which is the surface thereof) of the reflector 12 is a quadratic curved surface (for example, a parabolic surface or an elliptical surface). That is, the macro shape of the cross section of the reflecting portion 124 (reflecting surface) when viewed in the cross section shown in FIG. 5 draws a quadratic curve.

  The reflector 12 and the light source substrate 11 are relatively positioned so that each LED 15 is arranged on the focal point of the quadratic curve of such a reflection unit 124.

At least three of the holes 135a provided at the six corners of the lower flange 135 are screw holes. As shown in FIG. 3, three screw hole portions 39 are provided on the bottom of the base cover 30 at positions corresponding to the three screw holes. Thereby, the inner cover 13 is fixed to the base cover 30 with the screw (see FIG. 5) N2. Thereby, the light source unit 10 is attached to the container 50 including the base cover 30.

  The light source board 11, the power supply board B1, and the control board B2 are connected by a cable group 16. Two attachment holes 38 for connecting two harnesses 58 (see FIGS. 3 and 5) are provided at predetermined locations on the side peripheral wall 32 of the base cover 30. The cable group 17 for external connection such as the power supply board B1 is drawn out of the lamp device 100 through these harnesses 58.

3) Attaching the louver FIGS. 7A to 7C are plan views of the louver 90 having different incident angles.

  The louver 90A shown in FIG. 7A has a light emission angle of 225 ° and is shared by the bow lamp 1001 and the central mast lamp 1003. The louver 90B shown in FIG. 7B has an emission angle of 112.5 ° and is shared by the left and right lamps 1004. A louver 90C shown in FIG. 7C has an emission angle of 135 ° and is used for a stern light 1002 and a pulling boat light.

  One of the technical thoughts is that one louver 90 or a plurality of louvers 90A to C shown in FIGS. 7A to 7C is installed in one of a plurality of different installation angles around the light source unit 10. It can be installed in the main body of the lamp device 100 at the corner. In order to realize this, the housing 50 is provided with attachment portions of the louver 90 corresponding to the plurality of installation angles of the louver 90. Specifically, the container 50 is configured as follows.

  8 is a perspective view showing the outer cover 20, and FIG. 9 is a plan view thereof. The outer cover 20 constituting a part of the container 50 has a side peripheral portion 23 (functioning as a part or all of the light-transmitting region) 23 that mainly emits light from the light source unit 10 to the outside. In addition, the outer cover 20 has the protruding portion 21 that protrudes outward from the side peripheral portion 23 as described above. The projecting portion 21 has an attachment region 25 including a plurality of attachment portions of the louver 90.

  For example, the attachment region 25 includes a circumferential groove 26 and a locking groove 27 as an attachment portion. The circumferential groove 26 is a groove that is provided over the entire circumference of 360 ° along the outer shape of the side circumferential portion 23 and in which the main body 93 of the louver 90 is disposed. The locking grooves 27 are respectively connected to the circumferential grooves 26 at predetermined angular positions around the circumferential grooves 26, and engage with the blade portions 95 of the louver 90. When the blade portion 95 of the louver 90 is engaged with two predetermined locking grooves 27 among the plurality of locking grooves 27, the movement of the louver 90 around the z-axis is substantially restricted and locked.

  7A to 7C, each louver 90 according to the present embodiment has an engagement rib 94 as an engagement portion that can be engaged with the locking groove 27. In this case, the locking groove 27 functions as a first engaging portion, and the engaging rib 94 functions as a second engaging portion. For example, the engagement rib 94 is provided so as to protrude outward from the main body 93 and is formed long in a direction (vertical direction) substantially orthogonal to the circumferential direction of the main body 93.

  As shown in FIG. 7A, the engaging rib 94 of the louver 90 </ b> A is provided at the central angular position of the main body portion 93. As shown in FIG. 7B, the engagement rib 94 of the louver 90 </ b> B is provided so as to be shifted from the central angular position of the main body portion 93 toward the one blade portion 95. For example, the engagement rib 94 is provided at a position 60 ° to 70 ° away from the angular position of one blade portion 95 (the blade portion closer to the engagement rib 94). As shown in FIG. 7C, the engagement rib 94 of the louver 90 </ b> C is provided at the central angular position of the main body portion 93.

  Similarly to the outer cover 20, the lid 70 also has a mounting region 75 for the louver 90 including a circumferential groove 76 (see FIG. 5) and a locking groove 77 (see FIGS. 1 and 2). Specifically, the lid 70 has an attachment region 75 at the outer peripheral edge at the lower end. In each of the attachment regions 25 of the outer cover 20 and the lid 70 in FIG. 5, only the circumferential grooves 26 and 76 are drawn depending on the cross-sectional positions, and the locking grooves 27 and 77 are not drawn.

  The arrangement of the locking grooves 77 of the lid 70 is the same angle as that of the locking grooves 27 of the outer cover 20. Accordingly, the louver 90 is attached to the lamp body such that the attachment region 25 of the outer cover 20 and the attachment region 75 of the lid 70 sandwich the louver 90.

  FIG. 10 is a plan view schematically showing the angular arrangement of the locking groove 27 in the attachment region 25 of the outer cover 20 (and the lid 70), in particular. This figure shows the angular arrangement of the locking grooves 27 with the reference mark 72 of the lid 70 facing upward in the figure. As described above, the direction in which the reference mark 72 faces is the bow direction when viewed from the center of the hull. In the figure, the bow direction is indicated by a white arrow.

  Hereinafter, for convenience of explanation, the angle in the bow direction (y direction) is set to 0 °, and with reference to the 0 °, the clockwise direction is positive and the counterclockwise direction is a negative angle when viewed from the z-axis. And That is, the angular range of the entire circumference is set as 0 ° to ± 180 °.

  The respective locking grooves a, b, b ', c, c', d, d ', e are respectively arranged at the following angular positions. The center for defining the “angular position” here substantially coincides with the point on the light source central axis.

a: 0 °
b, b ′: ± 12.5 °
c, c ′: ± 107.5 °
d, d ′: ± 115 °
e: ± 180 °

  These angles are values based on the illuminating angle of the louver 90, and can be appropriately changed based on changes in the illuminating angle according to laws and regulations, or based on fine adjustment of the installation angle of the louver 90.

  11A to 11D show, for example, the installation angle of the louver 90 (see FIGS. 7A to 7C) for each lamp 100 installed in each place of one hull of the locking grooves 27 of the outer cover 20 (and the lid 70). Shown in relation to angular position. The bow direction is indicated by a white arrow.

  FIG. 11A shows the installation angle in the bowlight (or central mastlight). In this case, the blade portion 95 of the louver 90A shown in FIG. 7A is engaged with the locking grooves d and d ', and the engagement rib 94 is engaged with the locking groove e.

  FIG. 11B shows the installation angle for the port lights. In this case, the blade portion 95 of the louver 90B shown in FIG. 7B is engaged with the locking grooves b and d ', and the engagement rib 94 is engaged with the locking groove e. FIG. 11C shows the installation angle in the starlight. In this case, the blade portion 95 of the louver 90B is engaged with the locking grooves b 'and d, and the engaging rib 94 is engaged with the locking groove e. That is, the common louver 90B for the lantern is attached in a state in which the port and the starboard face each other upside down. As described above, the engaging rib 94 of the louver 90B for the lantern is provided on the main body 93 at an angular position so as to engage with the locking groove e at an angular position of ± 180 °.
