(First embodiment)
Hereinafter, the lighting fixture of 1st Embodiment which concerns on this invention is demonstrated using drawing.
As shown in FIG. 1, the lighting apparatus 10A according to the embodiment of the present invention can be used as a street lamp by being attached to a support column 11 as an attached portion that is attached to a road or the like, for example.
As shown in FIGS. 2A and 2B, the lighting fixture 10A includes a lamp body 20A and a mounting portion 30A that is provided at one end of the lamp body 20A and is attached to the column 11.
In the following description, the mounting portion 30A side of the lamp body 20A and the like is referred to as a base end side (base end portion), and the side opposite to the mounting portion 30A is referred to as a front end side (tip end portion).

The attachment portion 30 </ b> A has left and right attachment plates 31.
The left and right mounting plates 31 are connected and integrated by a pair of upper and lower connecting plates 35 at the proximal end portion.
The connecting plate 35 is provided with a curved portion 351 so as to follow the outer surface of the column 11 when attached.
The left and right mounting plates 31 have a support portion 32 that supports the lamp body 20 </ b> A on the distal end side, and a bracket 33 for mounting on the support column 11 on the proximal end side.
The bracket 33 is inclined so that the support portion 32 side (tip side) is high and the base end side is low, and an oval mounting hole 34 is provided along the bracket 33.

Therefore, when the attachment portion 30A is attached to the attachment plate (not shown) provided in the support column 11 via the attachment hole 34, the upper and lower curved portions 351 of the connecting plate 35 come into contact with the outer peripheral surface of the support column 11. 33 and the attachment hole 34 are attached along the column 11.
As a result, the lamp body 20A is attached to the support column 11 while being inclined so that the distal end side is higher than the proximal end side (see FIG. 1).

The lamp body 20A includes a top plate 21A and a translucent cover 22 attached to the lower side of the top plate 21A.
As shown in FIG. 2A, the translucent cover 22 is rotatably provided at the tip of the top plate 21A via a hinge portion 221, and opens and closes in the direction of arrow A in FIG.
Although not shown, the translucent cover 22 is fixed to the top plate 21A in a closed state.

As shown in FIGS. 3 and 4, the top plate 21 </ b> A has an overall rectangular plate shape and includes a chamfer 23 extending downward from the outer peripheral edge of the top plate 21 </ b> A.
The top plate 21A can be integrally formed by aluminum die casting.
At this time, the mounting portion 30A described above can be formed integrally with the top plate 21A.
The top plate 21A and the attachment portion 30A are desirably painted on the surface exposed to the outside, and at this time, it is desirable to use a water-repellent paint.

The chamfered portion 23 has an inclined surface 231 that is continuous with the upper surface (top surface) 24 of the top plate 21A and is inclined outwardly downward.
The chamfer 23 has a recess 232 on the lower surface, and the upper end 222 of the translucent cover 22 can be fitted therein.
The upper end portion 222 of the translucent cover 22 is provided with an engaging portion 223 that protrudes outward, so that the translucent cover 22 is sealed when the translucent cover 22 is closed.

As shown in FIG. 3, the inclination angle θ1 of the inclined surface 231 with respect to the horizontal plane (surface perpendicular to the vertical line) HL is preferably 60 degrees or more.
This is because when there is a gradient of 60 degrees or more, snow can be dropped in a small amount, which is effective in preventing snow accumulation.

As shown in FIGS. 2A and 6, the top plate 21 </ b> A has a concave cross section in which the central portion in the width direction of the upper surface 24 is recessed downward.
For example, as shown in FIG. 3, a trough line 25 that continues for a predetermined length from the distal end of the top plate 21 </ b> A toward the proximal end side is provided at the center in the width direction of the upper surface 24. The valley line 25 can be discontinuous.
The valley line 25 is provided at the same depth position in the longitudinal direction on the upper surface 24, and has a pair of inclined surfaces 26 that descend toward the valley line 25 on both sides of the valley line 25.

Thereby, the top plate 21A has a substantially V-shaped cross section.
In addition, the inclination angle θ2 formed by the inclined surface 26 with respect to the horizontal plane HL can be, for example, about 3 degrees.
Further, it is possible even when the left and right inclined surfaces 26 are asymmetric and the inclination angle θ2 is different.
Further, the inclined surface 26 is not limited to a flat surface, and may be a concave surface recessed downward.

As shown in FIGS. 2A and 6, a recess 27 is provided on the mounting portion side of the top surface 24 of the top plate 21 </ b> A.
The bottom surface 272 of the recess 27 is provided at the same depth position as the depth position of the valley line 25 or at a position (downward) deeper than the depth position of the valley line 25, and is provided at the same depth position in the longitudinal direction. It has been.
The concave portion 27 has a distal end side end surface 274 on the distal end side and an opening 271 on the attachment portion side.
Further, on both sides of the recess 27, ribs 29 that protrude upward and continue for a predetermined length up to the mounting portion side are provided (see FIGS. 2A and 4).

The concave portion 27 is provided with a constant width W1 from the distal end side toward the proximal end side, and has a base portion 28 whose upper surface has the same inclination as the inclined surface 26 on the proximal end side.
For this reason, the width of the concave portion 27 is gradually reduced by the base portion 28, and the opening 271 has a width W2. The opening area of the opening 271 is smaller than the cross-sectional area of the general portion having the constant width W1.
As shown in FIG. 5, a space 281 is formed inside the base portion 28, and an electric wire 44 that electrically connects a power source portion 43 and a commercial power source, which will be described later, can be wired.

As shown in FIGS. 2B and 4, the light emitting unit is provided on the lower surface (convex portion) 273 of the concave portion 27 as the lower surface of the top plate 21 </ b> A, that is, on the side opposite to the upper surface 24 of the top plate 21 </ b> A. 40 is attached.
The light emitting unit 40 includes a circuit board 41 attached to the lower surface 273 of the recess 27, a plurality of LED units 42 mounted on the mounting surface 413 of the circuit board 41, and a power supply unit 43.
Note that a brightness sensor 45 (see FIG. 2B) can be attached to the front end side of the power supply unit 43 so that the light emitting unit 40 is turned on when the surroundings are darkened and is turned off when the surroundings are brightened.

As shown in FIG. 2B, the longitudinal dimension of the circuit board 41 is such that the front end side end surface 411 of the circuit board 41 protrudes from the front end side end face 274 (see FIG. 6) of the recess 27 to the front end side. It is possible.
However, the longitudinal direction range RL where the circuit pattern is provided in the circuit board 41 is at least within the range of the lower surface 273 of the recess 27 (see FIG. 2B).

Also, as shown in FIG. 4, the width dimension of the circuit board 41 can be larger than the width dimension of the recess 27, but the width direction range RW of the circuit board 41 provided with the circuit pattern is , At least within the range of the lower surface 273 of the recess 27.
As a result, the back surface 412 in a range where the circuit pattern which is a heat generating portion is provided on the circuit board 41 comes into contact with the lower surface 273 of the recess 27, and the heat of the circuit board 41 is transferred from the recess 27 to the top plate 21A. Since it is transmitted, it is efficiently dissipated.

The effect of 10 A of lighting fixtures of 1st Embodiment concerning this invention is demonstrated.
As shown in FIG. 1, when the attachment portion 30A is attached to the column 11, the upper surface 24 of the lamp body 20A is inclined so that the tip side is higher than the horizontal plane HL.
As shown in FIG. 2A, the upper surface 24 is formed in a substantially concave shape in cross section for a predetermined length from the distal end side to the proximal end side.
For this reason, it can control so that the rain and snow which fell on the upper surface 24 of 20 A of lamps may flow to the support | pillar 11 side which is the lower side.
Further, even when an icicle is generated by rain or snow that has fallen, it occurs on the side of the support column 11, so that it is safe even if the icicle falls.
Furthermore, since an icicle is generated on the support 11 side, the lower part can be illuminated without blocking the light emitted from the lamp 20A.

Further, as shown in FIGS. 2A and 6, the upper surface 24 has a valley line 25 that continues for a predetermined length from the side opposite to the attachment part 30 </ b> A to the attachment part 30 </ b> A side, and a pair of slopes toward the valley line 25. It is formed in a substantially V-shaped cross section having a surface 26.
For this reason, the rain water etc. which fell on the upper surface 24 can be reliably flowed to the support | pillar 11 side.

  As shown in FIGS. 3 and 4, the lamp body 20 </ b> A is adjacent to the upper surface 24 and the chamfered portion 23 provided toward the translucent cover 22 is inclined by 60 degrees or more with respect to the horizontal plane HL. Therefore, it is difficult for snow to accumulate on the lamp body 20A.

Further, as shown in FIGS. 2A and 4, a rib 29 that is continuous for a predetermined length from the side opposite to the attachment portion 30 </ b> A to the attachment portion 30 </ b> A side is provided on the upper surface 24.
For this reason, even when heavy rain falls, rainwater or the like that has fallen on the inside of the rib 29 can surely flow to the support column 11 side.

  Further, as shown in FIGS. 2A and 6, the concave portion 27 that opens (opens 271) on the attachment portion 30 </ b> A side is provided on the attachment portion 30 </ b> A side on the upper surface 24. Can be streamed together.

Further, as shown in FIGS. 2A and 5, the opening area of the opening 271 of the recess 27 is larger than the cross-sectional area of the general portion orthogonal to the line connecting the distal end side and the proximal end side of the recess 27. Since it is small, it is easy to collect rain water etc. in the recessed part 27, and can flow vigorously.
Further, a space 281 such as the electric wire 44 can be secured.

Further, as shown in FIGS. 2B and 4, the back surface 412 of the circuit board 41 on which the LED unit 42 is mounted in the light emitting unit 40 on the lower surface 273 of the concave portion 27 on the opposite side of the upper surface 24 in the lamp body 20A. The circuit pattern range at is brought into contact.
Thereby, it is possible to prevent the water accumulated in the concave portion 27 from freezing due to the heat generated by the circuit board 41, so that rainwater or the like can be reliably flowed to the column 11 side.

In the lighting fixture 10C shown in FIG. 10, the angles α1 and α2 formed by the inclined surface 26 are larger on the distal end side (α1) so that the distal end side of the valley line 25 provided on the top plate 21C is higher than the proximal end side. It was made smaller on the base end side (α2).
Further, the bracket 33 and the mounting hole 34 of the mounting portion 30C are provided in the vertical direction of the lamp body 20C.
Even if the lamp body 20C is mounted horizontally on the column 11 via the mounting portion 30C, the valley line 25 is shallower (higher) at the distal end side and deeper (lower) at the proximal end side, so it falls on the top plate 21C. Rainwater etc. can flow to the base end side.

  Moreover, it is also possible to provide the trough line 25 provided in the top plate 21D from the middle in the longitudinal direction to the base end side, and provide the inclined surface 54 on the front end side of the trough line 25 as in the lighting fixture 10D illustrated in FIG. .
