The pole 3 is provided with a storage portion (not shown) for storing a lighting device (power supply) for the light source in the lamp body 5 at a predetermined height from the ground.
The lamp body 5 includes a tubular glove 7, a shade 9 as a detachable lid that covers the top of the globe 7, and an outer shell 10 that supports the globe 7 and the shade 9. The globe 7 is a cylindrical body whose lower portion (base portion) is slightly smaller in diameter than the upper portion (tip portion), and radiates light from the globe 7 to illuminate the ground. The globe 7 is formed as a light diffusing cover, for example, with a resin or the like, and when illuminated, the entire surface of the globe 7 is brightened substantially uniformly as a whole, thereby improving the design. Further, the upper surface of the globe 7 has a stepped surface, and constitutes a diffusing portion 7A having a higher diffusibility than other portions.
The shade 9 is formed in a hollow conical shape and forms an internal space Q above the outer shell 10.

The outer shell 10 includes an annular frame (fixed portion) 11, a bottom portion 13, and a crosspiece 15 that extends vertically between the frame body 11 and the bottom portion 13. A plurality of the crosspieces 15 are provided on the annular frame 11 at substantially equal intervals (four in the present embodiment), and the lower portion extends along the globe 7 whose diameter is slightly smaller than that of the upper portion. A gap δ is formed between the globe 7 and the crosspiece 15.

The upper part of the mounting bracket 17 opens into the globe 7, and a wiring support 21 that extends into the pole 3 is fixed to the upper part. A wiring 23 passed through the pole 3 from a lighting device or a commercial power source is supported by the wiring support 21, and the wiring 23 is drawn above the globe 7. The wiring 23 is arranged in the wiring tube 25 extending from the mounting bracket 17 to the light source unit 30 so that the wiring 23 is not visible from the outside, and the wiring 23 is not shaded during lighting.

FIG. 5 is a plan view showing the light source unit 30. 6A and 6B are views showing the cast body 40, FIG. 6A being a plan view and FIG. 6B being a front view. 7 is a sectional view taken along line VII-VII in FIG. FIG. 8 is a longitudinal sectional view of the cast body 40. FIG. 8A shows the outer radiating fin 43A, and FIG. 8B shows the inner radiating fin 43B. FIG. 9 is a perspective view showing a cast body 40 to which the LED light source module 31 is attached. FIG. 10 is a perspective view of the cast body 40 showing the wiring boss 65, and FIG. 11 is a cross-sectional view of the cast body 40 showing the wiring boss 65. FIGS. 12A and 12B are perspective views showing the cast body 40 and the support fitting 50. FIG. 12A shows a state before fixing, and FIG. 12B shows a state after fixing.
As shown in FIGS. 3 and 5, the light source unit 30 includes a cast body 40 and a support fitting (support) 50 that supports the cast body 40 on the outer shell 10, and a plurality of LED light source modules (light emitting elements) 31. The LED light source unit 32 provided with is attached to the cast body 40.

  The cast body 40 is an attachment portion to which the LED light source module 31 is attached and functions as a heat radiating body, and is constituted by a molded body (for example, aluminum die casting in the present embodiment) formed by molding a material having excellent thermal conductivity with a molding die. Has been. The cast body 40 is formed smaller than the inner peripheral surface of the frame body 11 that supports the cast body 40, and is disposed with a space R therebetween as shown in FIG. The cast body 40 is disposed in the globe 7, and a portion substantially corresponding to the cast body 40 is the diffusion portion 7 </ b> A described above. Thereby, since the LED light source module 31 attached to the casting 40 and the casting 40 becomes difficult to see from the outside, the design can be improved.

As shown in FIG. 6, the cast body 40 is formed in a cylindrical shape that protrudes toward the ground as an irradiation surface, and the lower portion (tip portion) 40B has a diameter smaller than the upper portion (base portion) 40A. The cast body 40 has an upper cavity 40A and a lower part 40B and an internal cavity S.
The outer peripheral surface (side surface) 40C of the cast body 40 has a plurality of planar mounting surfaces 41, and the LED light source modules 31 are provided on the mounting surfaces 41, respectively. Since the lower part 40B of the cast body 40 has a slightly smaller diameter than the upper part 40A, the mounting surface 41 is an inclined surface directed obliquely downward. In the present embodiment, the four attachment surfaces 41 are arranged at equal intervals of 90 ° in the circumferential direction of the cast body 40, and the cast body 40 is formed in a rectangular tube shape.
The upper portion 40A of the cast body 40 is integrally provided with an extension portion 42 that extends outward from the mounting surface 41. The cast body 40 includes an extension portion 42 and a cylindrical body 49 other than the extension portion 42. It is prepared for. The extending portion 42 is formed in an annular shape over the circumferential direction of the cast body 40, and has a diameter that increases from the proximal end toward the distal end. The surface on the mounting surface 41 side of the extending portion 42 functions as the reflecting surface 42A. Since the light toward the lamp body 5 can be reflected to the irradiation surface by the extending portion 42, the light extraction efficiency of the lamp can be improved. Further, by forming the extending portion 42 in an annular shape, the light of the LED light source module 31 can be reflected to the entire periphery of the side of the lamp body 5, so that the entire periphery of the side of the lamp body 5 can be illuminated. Note that the reflecting surface 42A of the extending portion 42 may be left on the surface of the molded product if the roughness of the surface of the molded product is sufficient for the reflecting surface, and paint or mirror finish is applied to the extending portion 42 on the surface of the molded product. The reflective surface 42A may be formed by applying, or a reflective mirror may be separately provided on the extending portion 42.

A plurality of heat radiation fins 43 are formed on the inner surface of the cast body 40. A plurality of the radiation fins 43 are provided in the circumferential direction at positions corresponding to the attachment surface 41 (the back surface of the attachment surface 41), and constitute a radiation fin unit 44 for each attachment surface 41. Each radiating fin 43 is provided from the upper part 40 </ b> A to the lower part 40 </ b> B of the cast body 40. In this embodiment, each radiating fin unit 44 has five radiating fins 43, and the five radiating fins 43 include two radiating fins 43 </ b> A on both outer sides and three radiating fins 43 </ b> B on the inner side. It consists of. As shown in FIG. 7, between the three inner radiation fins 43B, a portion of the base body 45 where the radiation fins 43B are erected is formed thicker than the other portions (in this embodiment, 1 mm thicker). Yes. Thereby, the heat dissipation of the center of the attachment surface 41 can be improved.
Further, as shown in FIG. 8, the outer two heat dissipating fins 43A have a shape protruding in a substantially rectangular shape inside, and the three inner heat dissipating fins 43B have a shape protruding in a substantially triangular shape on the inner side. Further, the height (depth) is larger than that of the outer radiation fins 43A. Thereby, since the surface area of the three inner radiation fins 43B is increased, the heat radiation property at the center of the mounting surface 41 can be improved.
In addition, about the number and shape of the radiation fin 43, and the thickness of the base | substrate 45, it is not limited to this, It can change suitably according to required heat dissipation.

  The LED light source unit 32 constitutes the light source of the street light 1, and as shown in FIG. 9, the LED light source module 31 that is a COB type LED is fixed to the mounting surface 41 with screws using an LED socket 33. The LED socket 33 is made of, for example, ceramic having high thermal conductivity in order to efficiently transmit the heat generated by the LED light source module 31 to the back surface. The LED light source module 31 is a light emitting device having a chip-on-board (COB) structure in which a large number of LEDs are densely arranged on an LED substrate 34 to form a planar light emitting portion 31A having a substantially circular shape (which may be a quadrangle). is there. Since the LED light source module 31 has a large number of LEDs arranged densely, a lamp having a large light amount and a high luminance can be obtained. Since the LED light source module 31 is attached to the attachment surface 41 that is an inclined surface, the emitted light is directed obliquely downward, and the ground can be efficiently irradiated. The plurality of LED light source modules 31 are wired in series by electric wires 35.

An opening 46 communicating with the internal cavity S is provided between the mounting surfaces 41. Through these openings 46, the internal cavity S communicates with the space inside the globe 7 outside the cast body 40, and hot air circulates in the globe 7 as indicated by the dotted arrows in FIG. Thus, since the hot air in the globe 7 can be circulated, the inside of the globe 7 can be set to a substantially uniform temperature, and the heat of the LED light source module 31 is prevented from being trapped in the internal cavity S, The heat of the LED light source module 31 can be effectively radiated.
Since the LED light source module 31 is wired in series, one of the four openings 46 also serves as a drawing hole for drawing the electric wire 35 of the LED light source module 31 into the cast body 40.

As shown in FIGS. 10 and 11, on the inner surface of the cast body 40, a wiring boss (wiring presser) 65 for pressing the electric wire 35 of the LED light source module 31 is provided below the opening 46. The wiring boss 65 is a portion that is pressed by a push pin that opens a mold for forming the cast body 40, and extends in a columnar shape from the inner surface of the cast body 40. In the present embodiment, two cylindrical wiring bosses 65 are provided inside each opening 46. The wiring boss 65 extends from the lower portion 40 </ b> B (bottom surface) of the cast body 40.
The electric wires 35 connecting the LED light source modules 31 are formed to be relatively long so that they can be easily wired, and the extra length of the electric wires 35 is formed from the opening 46 so as to be hidden from the emission surface (outer peripheral surface 40C). It is drawn inside and hooked on the wiring boss 65 to be fixed. The opening 46 is formed in a size that is easy for an operator to put in when the electric wire 35 is routed into the opening 46. Even if the opening 46 is formed relatively large for the electric wire 35, the heat radiation fins 43 are provided on the back surface of the mounting surface 41, so that the heat radiation of the cast body 40 can be secured.

As described above, since the wiring boss 65 for holding the electric wire 35 is provided, the electric wire 35 is not scattered and is difficult to see from the outside of the globe 7, so that the design can be improved. Further, since the wiring boss 65 is integrally formed on the cast body 40, a separate wiring fixture is not required, the number of parts can be reduced, the manufacturing cost can be reduced, and the number of parts mounting steps can be reduced.
Since the wiring boss 65 is provided so as to serve as a portion to be pushed by the push pin, it is not necessary to separately provide a place to be pushed by the push pin, so that the structure of the cast body 40 can be simplified. Further, since the wiring boss 65 is provided inside the opening 46, the wiring boss 65 is difficult to see from the outside of the globe 7, so that the design can be improved. Further, since the wiring boss 65 is provided in the vicinity of the heat radiating fins 43, the heat radiating fins 43 can be formed relatively deep (that is, higher from the base body 45). In addition, since the wiring boss 65 is formed in a rod shape, the alienation of thermal convection can be suppressed and the molded product can be neatly formed as compared with the case where it is formed in a plate shape (wall shape), for example.

As shown in FIG. 5, the support metal fitting 50 is a member disposed between the frame body 11 and a cast body 40 formed smaller than the frame body 11, and is formed of, for example, a metal plate. The support fitting 50 is integrally provided with a support portion 51 that supports the cast body 40 and an attachment portion 52 that attaches the support fitting 50 to the frame body 11.
Specifically, the cast body 40 includes a contact piece 47 that comes into contact with the support fitting 50 and an engagement claw 48 that engages with the support fitting 50 on the outer peripheral edge of the extending portion 42. In the present embodiment, the contact piece 47 is provided at a position corresponding to the mounting surface 41, and a pair of engagement claws 48 are provided to face each other between the contact pieces 47.
The support fitting 50 has a central opening 53 and is formed in a ring shape. The central opening 53 includes an engagement hole 54 into which an engagement claw 48 provided on the outer periphery of the cast body 40 is inserted.

  When the cast body 40 is supported by the support fitting 50, as shown in FIG. 12, the engaging claws 48 of the cast body 40 are inserted into the engagement holes 54 of the support fitting 50, and the support fitting 50 is rotated (illustrated example). Then, the engaging claw 48 and the edge of the central opening 53 are engaged and positioned by rotating to the right. The support fitting 50 and the cast body 40 are fixed by a fastener such as a screw. And the casting body 40 is supported by the frame body 11 via the support metal fitting 50 by arrange | positioning the attachment part 52 of the support metal fitting 50 on the frame body 11, and fixing the support metal fitting 50 with fasteners, such as a screw. The

Thus, since the heat radiating body is the cast body 40, the number of parts can be reduced compared with the case where the heat radiating body is formed of a metal plate, and the manufacturing process can be simplified. Moreover, compared with the case where a heat radiator is formed with a metal plate, the width of the heat dissipating fins 43 can be increased, and heat dissipation can be improved. Furthermore, when the heat radiator is formed of a metal plate, it is necessary to add a positioning member of the LED light source module 31 to the mounting surface 41 or to perform additional machining on the mounting surface 41. Since the positioning member can be integrally formed, the number of parts can be reduced and the manufacturing process can be simplified.
In addition to this, since the cast body 40 that is a heat radiating body and the support fitting 50 that is the support portion of the cast body 40 are separated, the cast body 40 can be used for various products by changing the support fitting 50. The versatility of the cast body 40 can be improved. Moreover, since the casting 40 can be reduced in size, and the mold can be reduced in size and simplified, the casting 40 can be manufactured inexpensively and easily. Furthermore, since the material of the support metal fitting 50 can be different from the cast body 40 that functions as a heat radiator, for example, when heat dissipation performance and corrosion resistance are not required, a relatively inexpensive material is used for the support metal fitting 50. Thus, the manufacturing cost can be reduced. Since the support fitting 50 is formed in a ring shape to form a single member, the number of parts of the support fitting 50 can be reduced and the manufacturing process can be simplified.

  In addition, outer peripheral openings 55 are provided at positions corresponding to the LED light source modules 31 on the outer peripheral portion of the support fitting 50. The central opening 53 communicates with the inner cavity S of the casting 40 and the inner space Q of the shade 9, and the outer peripheral opening 55 communicates the space outside the casting 40 and inside the globe 7 with the inner space Q of the shade 9. However, hot air circulates in the globe 7 and the shade 9 as indicated by dotted arrows in FIG.

  In the lamp body 5 of this embodiment, as shown in FIG. 2, since the shade 9 as a lid has an internal space Q inside, the power source P can be arranged in the internal space Q. In this embodiment, as shown in FIGS. 2 and 12, the power supply fixing part 56 provided so as to straddle the central opening 53 is formed in the support metal fitting 50, and the power supply P arranged in the internal space Q is the power supply fixed. It is fixed to the part 56. In the figure, reference numeral 52 </ b> A is a notch provided in the attachment portion 52. The frame 11 is formed with a plurality (three) of fixed bosses 11A for fixing the shade 9 and the notch 52A is for avoiding the fixed bosses 11A. Note that the number of the fixed bosses 11A is not limited to three, and the cutout portion 52A can be omitted depending on the arrangement position of the fixed bosses 11A.

The wiring pipe 25 that draws the wiring 23 from the outside extends to the internal cavity S of the cast body 40, and the wiring 23 drawn from the wiring pipe 25 is drawn from the central opening 53 into the internal space Q inside the shade 9 and is supplied with power. Connected to P.
A power supply line (not shown) extending from the power supply P is drawn into the internal cavity S of the casting 40 from the central opening 53 and connected to the electric wire 35 of the LED light source module 31 drawn into the internal cavity S.

Here, since the plurality of LED light source modules 31 are wired in series, one power line is provided for the plurality of LED light source modules 31, and the lamp body 5 is placed at a predetermined position in the circumferential direction of the cast body 40. It has a power connection point B for connecting the electric wire 35 of the light source module 31 and the power line. The cast body 40 is not rotationally symmetric with respect to the support metal fitting 50, and the direction in which the cast body 40 is fixed to the frame body 11 is defined. Therefore, the predetermined opening 46 must be used as a lead-in hole for the electric wire 35.
Therefore, in the present embodiment, a mark indicating a position corresponding to the power connection point B is integrally formed on the cast body 40.

FIG. 13 is a perspective view showing the lamp body 5 from below.
As shown in FIGS. 7 and 13, the casting body 40 is integrally formed with a work procedure mark 61 indicating the work procedure of the plurality of LED light source modules 31 and a polarity mark 63 indicating the polarity of the LED light source modules 31. ing.
The work procedure mark 61 is a mark indicating the order of mounting and wiring of the LED light source modules 31, and the order is shown by the number of the LED light source modules 31. In the present embodiment, Arabic numerals (1, 2, 3, 4) are integrally formed as work procedure marks 61 at the positions corresponding to the LED light source modules 31 in the extending portion 42. An opening 46 between the work procedure marks 61 of “1” and “4” serves as a lead-in hole for the electric wire 35, and the work procedure mark 61 is provided as a mark indicating a position corresponding to the power connection point B.

  As described above, since the mark indicating the position corresponding to the power supply connection point B is provided, it is possible to reduce the trouble of checking the power supply connection point B (which is the lead-in hole in the opening 46) of the lamp body 5, and thus a plurality of LEDs The light source module 31 can be easily attached to the cast body 40, and the manufacturing time can be shortened. By providing the work procedure mark 61, it is only necessary to attach and wire the LED light source module 31 along the work procedure mark 61. Therefore, the operator does not have to consider the order of attaching the LED light source modules 31, and thus the installation work is easy. In addition, the manufacturing time can be shortened. Moreover, the mistake which concerns on attachment of the LED light source module 31 can also be prevented.

  The polarity mark 63 is a mark indicating the positive pole and / or the negative pole of the LED light source module 31. In the present embodiment, a minus sign (−) is integrally formed as a polarity mark 63 at a position corresponding to each LED light source module 31 in the extending portion 42. By providing the polarity mark 63, it is possible to prevent a mistake in the mounting direction and wiring of the LED light source module 31. Moreover, the shaping | molding die of the casting 40 can be simplified by making the polarity mark 63 only a minus sign. Further, since the minus sign has a simpler shape than the plus sign, the polarity mark 63 can be easily removed from the mold, and damage to the polarity mark 63 when removed from the mold can be suppressed. When a plus sign (+) is formed, if there is a defect in the formation of the mark, it may become a minus sign (-), and an event in which the mark cannot be correctly identified is foreseen.

By the way, after the street light 1 is installed, there is a case where it is desired to attach a light shielding plate from the vicinity, and it is difficult to incorporate the light shielding plate in advance when the product is shipped.
Here, when a lamp is used as the light source, it is possible to disassemble the lamp body and attach a light shielding plate inside the globe. However, when a light emitting element is used as the light source, it is not desirable to disassemble the lamp body, and therefore, a work process has been performed in which a tap process for attaching a light shielding plate is performed on the lamp body in advance.
Therefore, in this embodiment, the light shielding plate can be easily externally attached.

14A and 14B are views showing the street light 1. FIG. 14A is a state before attachment, FIG. 14B is a state where the fixing bracket 71 is attached, and FIG. 14C is a state where the light shielding plate 70 is further attached. Indicates. FIG. 15 is a cross-sectional view showing the crosspiece 15 portion.
As shown in FIG. 14, the light shielding plate 70 is a thin plate-shaped light shielding material formed in a size and shape that covers the adjacent bars 15 and the space between them (the width of the lamp body 5 in the circumferential direction of about 90 °), Both side portions are fixed to the crosspiece 15 via fixing metal fittings (engaging means) 71, respectively.

As shown in FIG. 15, the crosspiece 15 is formed in a rectangular tube shape having an inner side (back side) opened, and integrally includes a surface portion 81 and side portions 82 and 82 on both sides of the surface portion 81. The crosspiece 15 is wide from the front surface 15A to the back surface 15B.
Each fixing bracket 71 is formed by bending a single plate material, and includes a front plate 71A that contacts the surface portion 81 of the crosspiece 15, and an extension portion 71B that extends from one side of the front plate 71A along the front plate 71A. The side plate 71C extends from the other side portion of the front plate 71A and contacts the side surface portion 82 of the crosspiece 15 and the engagement portion 71D that enters the opening of the crosspiece 15 are integrally provided. As described above with reference to FIG. 4, the gap δ is formed between the globe 7 and the crosspiece 15, and the engaging portion 71 </ b> D is inserted into the opening of the crosspiece 15 from the gap δ. Further, the angle between the side plate 71C and the engaging portion 71D is set to an acute angle, and the fixing bracket 71 is caught by the crosspiece 15 when the engaging portion 71D enters the opening at an acute angle.
A fastening hole 71B1 for fastening is formed in the extension portion 71B. A fastening hole 70A is formed in the light shielding plate 70 at a position corresponding to the fastening hole 71B1.

  When attaching the light shielding plate 70 to the lamp body 5, first, the two fixing brackets 71 are engaged with the crosspiece 15. That is, the engaging part 71 </ b> D of the fixing metal 71 is inserted into the opening of the crosspiece 15 and the fixing metal 71 is hooked on the crosspiece 15. In this state, the light shielding plate 70 is directed to the fixing bracket 71 so that the fastening hole 70A of the light shielding plate 70 overlaps the fastening hole 71B1 of the fixing bracket 71, and fasteners such as screws (not shown) are attached to the fastening holes 70A and 71B1. Insert and fix. Since the light shielding plate 70 has a thin flat plate shape, by fixing the light shielding plate 70 to the fixing metal 71, the light shielding plate 70 has a shape along the shape of the lamp body 5.

  Thus, since the light shielding plate 70 is fixed to the crosspiece 15 by the fixing bracket 71 inserted into the gap δ and engaged with the crosspiece 15, the lamp body 5 is subjected to special processing such as tapping for attaching the light shielding plate. Therefore, the light shielding plate 70 can be easily externally attached, and the cost increase of the lamp body 5 related to the attachment of the light shielding plate 70 can be prevented. Moreover, since it is not necessary to disassemble the lamp body 5, it is possible to prevent the lamp body 5 from being broken or broken.
