The lamp body 5 includes a cylindrical glove 7, a crucible 9 as a removable lid covering an upper portion of the glove 7, and an outer shell 10 for supporting the glove 7 and the crucible 9. The globe 7 is a cylindrical body whose lower portion (base) has a diameter slightly smaller than that of the upper portion (tip portion), and light is emitted from the globe 7 to illuminate the ground. The globe 7 is formed of, for example, a resin or the like as a light diffusive cover, and when illuminated, the entire surface of the globe 7 is substantially uniformly brightened overall and the design is improved. In addition, the upper part of the globe 7 is formed in a step-like surface, and constitutes a diffusion part 7A having a higher diffusion property than the other parts.
The weir 9 is formed in a hollow conical shape and forms an internal space Q above the shell 10.

The outer shell 10 is configured to include an annular frame (fixed portion) 11, a bottom 13, and a bar 15 extending vertically between the frame 11 and the bottom 13. A plurality of (four in the present embodiment) crosspieces 15 are provided on the annular frame 11 at substantially equal intervals, and the lower part extends along the globe 7 slightly smaller in diameter than the upper part.

A wire 23 passed through the pole 3 from a lighting device or a commercial power source is supported by the wire support 21, and the wire 23 is drawn above the globe 7. The wiring 23 is disposed in the wiring pipe 25 extending from the mounting bracket 17 to the light source unit 30, so that the wiring 23 can not be seen from the outside, and the wiring 23 does not become shaded at the time of lighting.

FIG. 5 is a plan view showing the light source unit 30. As shown in FIG. FIG. 6 is a view showing a casting 40, FIG. 6 (A) is a plan view, and FIG. 6 (B) is a front view. 7 is a cross-sectional view taken along the line VII-VII in FIG. FIG. 8 is a longitudinal sectional view of the cast body 40, and FIG. 8 (A) shows the outer radiation fin 43A, and FIG. 8 (B) shows the inner radiation fin 43B. FIG. 9 is a perspective view showing a casting 40 to which the LED light source module 31 is attached. FIG. 10 is a perspective view of the casting 40 showing the wiring boss 65, and FIG. 11 is a cross-sectional view of the casting 40 showing the wiring boss 65. As shown in FIG. FIG. 12 is a perspective view showing the casting 40 and the support fitting 50, and FIG. 12 (A) shows a state before fixing, and FIG. 12 (B) shows a state after fixing.
The light source unit 30, as shown in FIGS. 3 and 5, includes a casting 40 and a support bracket (support) 50 for supporting the casting 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, and is comprised.

  The cast body 40 is a mounting portion to which the LED light source module 31 is attached and functions as a heat radiating body, and is formed of a molded body (for example, aluminum die cast in this embodiment) formed by molding a material excellent in thermal conductivity It is done. The casting 40 is formed smaller than the inner circumferential surface of the frame 11 supporting the casting 40, and as shown in FIG. The cast body 40 is disposed in the glove 7 and the portion substantially corresponding to the cast body 40 is the above-described diffusion portion 7A. As a result, since the cast body 40 and the LED light source module 31 attached to the cast body 40 become 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 which is the irradiation surface, and the diameter of the lower portion (tip portion) 40B is smaller than that of the upper portion (base) 40A. The cast body 40 opens the upper portion 40A and the lower portion 40B and has an internal cavity S.
A plurality of flat mounting surfaces 41 are provided on the outer peripheral surface (side surface) 40C of the cast body 40, and the LED light source modules 31 are provided on each of the mounting surfaces 41, respectively. In the casting 40, the diameter of the lower portion 40B is slightly smaller than that of the upper portion 40A, so the mounting surface 41 is an inclined surface directed obliquely downward. In the present embodiment, four mounting surfaces 41 are arranged at equal intervals at 90 ° in the circumferential direction of the cast body 40, and the cast body 40 is formed in a square cylindrical shape.
In the upper portion 40A of the casting 40, an extension 42 extending outward from the mounting surface 41 is integrally provided, and the casting 40 comprises the extension 42 and a cylinder 49 other than the extension 42. It is configured to be equipped. The extension portion 42 is formed in an annular shape along the circumferential direction of the cast body 40, and the diameter is expanded from the proximal end toward the distal end. The surface on the attachment surface 41 side of the extension portion 42 functions as a reflection surface 42A. Since the light directed to the lamp main body 5 can be reflected to the irradiation surface by the extension part 42, the light extraction efficiency of the lamp can be improved. Further, since the light of the LED light source module 31 can be reflected to the entire periphery on the side of the lamp main body 5 by forming the extension part 42 in an annular shape, the entire periphery on the side of the lamp main body 5 can be illuminated. The reflection surface 42A of the extending portion 42 may be left as it is as long as the surface roughness of the molded article is sufficient for the reflecting surface, or the extending portion 42 may be coated with paint, mirror finish, etc. The reflecting surface 42 </ b> A may be formed by applying, or a reflecting mirror may be separately provided in the extending portion 42.

A plurality of radiation fins 43 are formed on the inner surface of the casting 40. A plurality of heat dissipating fins 43 are provided circumferentially at positions corresponding to the mounting surface 41 (the back surface of the mounting surface 41), and the heat dissipating fin unit 44 is configured for each mounting surface 41. The heat radiation fins 43 are provided from the upper portion 40A to the lower portion 40B of the casting 40. In the present embodiment, each heat dissipating fin unit 44 has five heat dissipating fins 43, and the five heat dissipating fins 43 include two heat dissipating fins 43A on both outer sides and three heat dissipating fins 43B on the inner side. It consists of As shown in FIG. 7, the base 45 of the portion where the heat dissipating fins 43B stand is formed between the inner three heat dissipating fins 43B so as to be thicker (1 mm thicker in this embodiment) than the other portions. There is. Thereby, the heat dissipation of the center of the attachment surface 41 can be improved.
Further, as shown in FIG. 8, the two outer heat radiation fins 43A are formed to protrude inward in a substantially rectangular shape, and the three inner heat radiation fins 43B are formed to protrude inward in a substantially triangular shape. Also, the height (depth) is also greater than the outer radiation fin 43A. As a result, the surface area of the inner three heat dissipating fins 43B is increased, so that the heat dissipating property at the center of the mounting surface 41 can be improved.
The number and shape of the heat dissipating fins 43 and the thickness of the base 45 are not limited to the above, and can be appropriately changed according to the required heat dissipating property.

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

An opening 46 communicating with the internal cavity S is provided between the mounting surfaces 41. The openings 46 allow the internal cavity S to communicate with the space outside the casting 40 and the inside of the glove 7 so that hot air circulates in the glove 7 as indicated by the dotted arrow in FIG. Thus, since the hot air in the glove 7 can be circulated, the temperature in the glove 7 can be made substantially uniform, and the heat of the LED light source module 31 is prevented from leaking into the internal cavity S. The heat of the LED light source module 31 can be dissipated effectively.
Since the LED light source modules 31 are wired in series, one of the four openings 46 also serves as a lead-in hole for drawing the electric wire 35 of the LED light source module 31 into the casting 40.

As shown in FIGS. 10 and 11, a wiring boss (wiring presser) 65 for pressing the electric wire 35 of the LED light source module 31 is provided at the lower portion of the opening 46 on the inner surface of the cast body 40. The wiring bosses 65 are portions pressed by the push pins that open the mold for molding the cast body 40 and extend 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 bosses 65 extend from the lower portion 40 B (bottom surface) of the casting 40.
The wires 35 connecting the LED light source modules 31 are formed relatively long to facilitate wiring, and the excess length portion of the wires 35 covers the opening 46 from the opening 46 so as to be hidden from the exit surface (the outer circumferential surface 40C). It is drawn inside and is hooked and fixed to the wiring boss 65. The opening 46 is sized so that the operator can easily insert the wire 35 into the opening 46. Even if the opening 46 is formed relatively large for the electric wire 35, since the radiation fin 43 is provided on the back surface of the mounting surface 41, the heat radiation of the cast body 40 can be secured.

As described above, since the wiring bosses 65 for holding the electric wires 35 are provided, the electric wires 35 are not scattered and it is difficult to see from the outside of the globe 7, so that the design can be improved. Further, since the wiring bosses 65 are integrally formed on the cast body 40, the number of parts can be reduced, the manufacturing cost can be reduced, and the number of mounting steps of parts can be reduced without requiring a separate wiring fixing tool.
Since the wiring bosses 65 are provided to also serve as the portions to be pushed by the push pins, there is no need to separately provide the portions to be pushed by the push pins, so the structure of the cast body 40 can be simplified. In addition, since the wiring bosses 65 are provided inside the opening 46, the wiring bosses 65 are difficult to see from the outside of the globe 7, so that the design can be improved. Further, since the wiring bosses 65 are provided in the vicinity of the heat dissipating fins 43, the heat dissipating fins 43 can be formed relatively deep (that is, high from the base 45). Moreover, since the wiring bosses 65 are formed in a bar shape, it is possible to suppress the alienation of the thermal convection and to form the molded article finely as compared with the case where the wiring bosses 65 are formed in a plate shape (wall shape).

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

  When supporting the cast body 40 on the support fitting 50, as shown in FIG. 12, the engagement claw 48 of the cast body 40 is inserted into the engagement hole 54 of the support fitting 50, and the support fitting 50 is rotated. Then, by rotating the gear clockwise, the engagement claw 48 and the edge of the central opening 53 are engaged and positioned. The support fitting 50 and the cast body 40 are fixed by a fastener such as a screw. The cast body 40 is supported by the frame 11 via the support fitting 50 by disposing the mounting portion 52 of the support fitting 50 on the frame 11 and fixing the support fitting 50 with a fastener such as a screw. Ru.

As described above, since the heat dissipating member is the cast body 40, the number of components can be reduced and the manufacturing process can be simplified as compared to the case where the heat dissipating member is formed of a metal plate. Further, the width of the heat dissipating fins 43 can be increased as compared with the case where the heat dissipating body is formed of a metal plate, and the heat dissipating property can be improved. Furthermore, in the case where the heat dissipating member is formed of a metal plate, it is necessary to add a positioning member for the LED light source module 31 to the mounting surface 41 or to add it to 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 which is a radiator and the support bracket 50 which is a support portion of the cast body 40 are separated, the cast body 40 can be used for various products by changing the support bracket 50. The versatility of the cast body 40 can be improved. In addition, since the casting 40 can be miniaturized and, consequently, the molding die can be miniaturized and simplified, the casting 40 can be manufactured inexpensively and easily. Furthermore, since the material of the support bracket 50 can be made different from the cast body 40 that functions as a heat sink, for example, when the heat radiation performance and corrosion resistance are not required, a relatively inexpensive material is used for the support bracket 50 Can reduce manufacturing costs. Since the support fitting 50 is formed in a ring shape into one member, the number of parts of the support fitting 50 can be reduced and the manufacturing process can be simplified.

  Further, outer peripheral openings 55 are respectively 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 brings the internal cavity S of the casting 40 into communication with the internal space Q of the crucible 9, and the outer peripheral opening 55 brings the internal space Q of the crucible 7 outside the casting 40 into the glove 7. The hot air circulates in the glove 7 and the weir 9 as indicated by the dotted arrow in FIG.

  In the lamp main body 5 of the present embodiment, as shown in FIG. 2, since the crucible 9 as the lid has the internal space Q inside, the power source P can be disposed in the internal space Q. In the present embodiment, as shown in FIGS. 2 and 12, a power supply fixing portion 56 provided so as to straddle the central opening 53 is formed in the support fitting 50, and the power supply P disposed in the internal space Q is fixed to the power supply. It is fixed to the part 56. In the figure, reference numeral 52A is a notch provided in the mounting portion 52. A plurality of (three) fixing bosses 11A for fixing the wedge 9 are formed in the frame 11, and the notch 52A is for avoiding the fixing boss 11A. The number of fixing bosses 11A is not limited to three, and the notch 52A may be omitted depending on the arrangement position of the fixing bosses 11A.

The wiring pipe 25 for drawing in 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 crucible 9 Connected to P
A power supply line (not shown) extending from the power supply P is drawn from the central opening 53 into the internal cavity S of the casting 40 and connected to the 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 supply line is provided for the plurality of LED light source modules 31, and the lamp body 5 is an LED at a predetermined position in the circumferential direction of the casting 40. It has a power supply connection point B for connecting the electric wire 35 of the light source module 31 and the power supply line. Since the casting 40 has a support structure to the support fitting 50 not in rotational symmetry, and the direction in which it is fixed to the frame 11 is defined, the predetermined opening 46 must be a lead-in hole of the electric wire 35.
So, in this embodiment, the mark which shows the position corresponding to the power supply connection location B is integrally formed in the cast body 40. As shown in FIG.

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

  As described above, since the mark indicating the position corresponding to the power connection point B is provided, it is possible to reduce the time and effort required to check the power connection point B of the lamp body 5 (which is the lead-in hole of the opening 46). The light source module 31 can be easily attached to the casting 40 and the manufacturing time can be shortened. Since the LED light source module 31 may be attached and wired along the operation procedure mark 61 by providing the operation procedure mark 61, the operator does not have to consider the mounting order of the LED light source module 31, so the mounting operation is easy. Also, the production 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, in the extension portion 42, a minus symbol (-) is integrally formed as the polarity mark 63 at a position corresponding to each of the LED light source modules 31. By providing the polarity mark 63, it is possible to prevent the mounting direction of the LED light source module 31 and the mistake of the wiring. Also, by making the polarity mark 63 only a minus sign, the mold of the casting 40 can be simplified. Furthermore, since the minus sign is simpler in shape than the plus sign, the polar mark 63 can be easily removed from the mold and damage to the polar mark 63 when removed from the mold can be suppressed. When forming a plus sign (+), if there is a defect in forming the mark, it may become a-(minus) mark, and the occurrence of an event that the mark can not be identified correctly is foreseen.

By the way, after the street light 1 is installed, there may be a case where the installation of a light shielding plate is required from the neighborhood, 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 also possible to disassemble the lamp body and attach a light shielding plate to the inside of the glove. However, when the light emitting element is used as the light source, since disassembly of the lamp body is not desirable, there has been a work process in which the lamp body is subjected to tapping for mounting the light shielding plate in advance.
Therefore, in the present embodiment, the light shielding plate can be easily attached externally.

FIG. 14 is a view showing the street lamp 1. FIG. 14 (A) is a state before mounting, FIG. 14 (B) is a state with the fixing bracket 71 attached, and (C) is a state with the light shielding plate 70 further attached. Indicates FIG. 15 is a cross-sectional view showing the crosspiece 15 part.
The light shielding plate 70 is a thin flat light shielding material formed in a size and shape to cover the adjacent crosspieces 15 and between them (a width of about 90 ° in the circumferential direction of the lamp main body 5) as shown in FIG. Both side portions are respectively fixed to the crosspiece 15 via fixing brackets (engaging means) 71.

As shown in FIG. 15, the crosspiece 15 is formed in a rectangular tube shape opened on the inner side (rear side), and integrally includes a surface portion 81 and side portions 82 and 82 on both sides of the surface portion 81. The crosspieces 15 are wider from the surface 15A to the back surface 15B.
Each fixing bracket 71 is formed by bending a single plate material, and a front plate 71A that contacts the surface portion 81 of the crosspiece 15, and an extension portion 71B extended along the front plate 71A from one side of the front plate 71A. A side plate 71C which extends from the other side of the front plate 71A and contacts the side surface 82 of the crosspiece 15, and an engaging part 71D which 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 71D 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 hooked on 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. Fastening holes 70A are formed in the light shielding plate 70 at positions corresponding to the fastening holes 71B1.

  When attaching the light shielding plate 70 to the lamp main body 5, first, the two fixing brackets 71 are engaged with the crosspieces 15. That is, the engaging portion 71D of the fixing bracket 71 is inserted into the opening of the crosspiece 15, and the fixing bracket 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 holes 70A of the light shielding plate 70 overlap the fastening holes 71B1 of the fixing bracket 71, and fasteners such as screws are not provided in the fastening holes 70A and 71B1 (not shown) Insert and fix. Since the light shielding plate 70 is in the form of a thin flat plate, fixing the light shielding plate 70 to the fixing bracket 71 makes the shape conform to the shape of the lamp body 5.

  As described above, 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 main body 5 is subjected to special processing such as tapping for light shielding plate attachment. Therefore, the light shielding plate 70 can be easily externally attached, and the cost increase of the lamp main body 5 related to the attachment of the light shielding plate 70 can be prevented. Further, since the disassembly of the lamp body 5 is not necessary, it is possible to prevent the breakdown and failure of the lamp body 5.

  As described above, according to the present embodiment, the lamp body 5 is configured by providing the globe 7 with the gaps δ inside the plurality of crosspieces 15, and the light shielding plate 70 covering the globe 7 is It is configured to be fixed to the crosspiece 15 by means of an engagement means which is inserted and engaged with the crosspiece 15. With this configuration, the light shielding plate 70 can be easily externally attached to the lamp body 5 without performing special processing such as tapping for light shielding plate attachment.

However, the above-mentioned embodiment is one mode of the present invention, and it is needless to say that it can be suitably changed in the range which does not deviate from the meaning of the present invention.
