Description

  The present invention relates to an illuminating lamp including a semiconductor light emitting element.

  An illumination lamp including a semiconductor light emitting element, also called an LED, has been proposed. For example, Patent Document 1 describes a road lamp including a plurality of COB-type LEDs mounted on an LED substrate in a lamp body. A light source chamber is provided in the lamp body, and an LED and an LED power source are assembled in the light source chamber.

JP 2014-175074 A

  In the road lamp described in Patent Document 1, an LED substrate on which LEDs that generate heat are mounted and a power source having low heat resistance are arranged adjacent to each other in the same space as a light source chamber. For this reason, the durability of the power source exposed to the heat generated by the LED may be lowered. In addition, since the LED substrate and the power source are arranged side by side, the space of the light source chamber is increased, and the lamp body may be enlarged.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide an illuminating lamp that improves durability and saves space for the components of the illuminating lamp.

  In order to achieve the above object, an illuminating lamp according to the present invention includes a housing, a translucent portion having translucency arranged in the housing, and a plurality of semiconductor light emitting elements arranged in a concentrated manner. A light-emitting unit disposed in the light-transmitting unit and a power-source unit of the light-emitting unit, wherein at least a part of the power-source unit is disposed in a region corresponding to the light-transmitting unit in the housing, and the light-emitting unit and the power-source unit are Spaced apart.

  In the above structure, the thickness of the light emitting portion including the semiconductor light emitting element can be kept low. For this reason, when the power supply unit disposed at least in a region corresponding to the light transmitting unit in the housing is disposed away from the light emitting unit while being close to the light emitting unit disposed in the light transmitting unit, The space occupied by the part and the light emitting part can be reduced. In addition, since the light emitting part in which a plurality of semiconductor light emitting elements are arranged in a concentrated manner generates heat in a larger amount than that in a diffused arrangement, the light emitting part receives from the light emitting part by arranging the power supply part apart. Heat can be reduced.

  At least a part of the power supply unit may be disposed on the back of the light emitting unit with respect to the light transmitting unit. In the above-described configuration, by arranging the power supply unit on the back of the light emitting unit, the space occupied by the power supply unit and the light emitting unit becomes smaller, and further space saving of the components of the illuminating lamp is possible.

  The illuminating lamp includes a power supply unit support that supports the power supply unit and a light emission unit support that supports the light emission unit. The power supply unit support also supports the light emission unit support. They may be spaced apart. In the above-described configuration, the light emitting unit support is disposed away from the power source unit. Therefore, it is suppressed that the heat which a light emission part produces is transmitted to a power supply part via a light emission part support body.

  The light emitting unit support has a plate shape, and a space in which at least a part of the power supply unit is disposed may be formed between the light emitting unit support and the power supply unit support. In the above-described configuration, the plate-like light emitting unit support may be interposed so as to block between the light emitting unit and the power supply unit. Therefore, it is reduced that the heat generated by the light emitting unit is directly transmitted to the power source unit.

  The light emitting unit support may be formed from a heat conductive material, and the power supply unit support may be formed from a material having lower thermal conductivity than the light emitting unit support. In the above-described configuration, the light emitting unit support body can dissipate heat generated by the light emitting unit. The power supply unit support suppresses the heat of the light emitting unit support from being transmitted to the power supply unit via the power supply unit support.

  The translucent part may protrude outward from the opening formed in the housing, and the light emitting part may be disposed in the translucent part or in the opening. In the above-described configuration, the heat generated by the light emitting part can be dissipated to the outside through the light transmitting part, whereby the heat generated by the light emitting part can be suppressed from entering the housing. Further, the light emitted from the light emitting part can be efficiently emitted to the outside through the light transmitting part.

  A plate-like light emitting unit support that supports the light emitting unit may be disposed inside the opening, and may be disposed behind the light emitting unit with respect to the light transmitting unit. In the above-described configuration, the light emitted from the light emitting part toward the inside of the housing from the opening can be reflected by the plate-like light emitting part support and radiated to the outside through the light transmitting part.

  The light emitting unit may include a lens body that covers the plurality of semiconductor light emitting elements and has translucency. In the above configuration, one lens body can be provided for a plurality of semiconductor light emitting elements. Therefore, the cost can be reduced.

  According to the illuminating lamp according to the present invention, it is possible to improve the durability and reduce the space of the constituent elements.

The housing 11 includes a base housing 11a to which the arm 3 is connected, and a cover 11b in which the globe 12 is disposed. The base housing 11a and the cover 11b may be made of any material, but in the present embodiment, the base housing 11a and the cover 11b are made of a plate made of a material having thermal conductivity. For example, the base housing 11a and the cover 11b can be made of a metal material having high thermal conductivity such as aluminum, aluminum alloy, alumina, magnesium alloy or the like. As described above, the casing 11 formed of a plate material has a shell-like configuration. Thereby, the heat generated in the illumination lamp 10 can be dissipated to the outside through the housing 11. Here, the globe 12 is an example of a translucent part. Here, the translucent part is used to directly or indirectly emit light emitted from the light emitting part inside the casing 11 of the illuminating lamp 10 and emitting light for illumination to the outside of the casing 11. It is a part provided in. For example, the translucent part may be a part through which the direct light from the light emitting part and the reflected light reflected by the reflecting plate or the like pass through the opening or glass surface provided in the housing 11.

  Each of the base housing 11a and the cover 11b constitutes a half of the housing 11, and is connected to each end portion via a hinge 11c. In the present embodiment, the hinge 11c connects the base housing 11a and the cover 11b at the position of the end of the base housing 11a opposite to the end to which the arm 3 is connected. However, the position of the hinge 11c is not limited to the above position. The cover 11b can rotate with respect to the base housing 11a around the hinge 11c to open and close the base housing 11a. When the cover 11b is rotated and the entire periphery of the cover 11b is fitted to the entire periphery of the base housing 11a, the base housing 11a is closed. The base housing 11a is opened by rotating the cover 11b fitted to the base housing 11a in the direction opposite to the direction of the rotation.

  The cover 11b has a flat mounting wall portion 11bb at a position facing the base housing 11a. The attachment wall portion 11bb is a wall portion to which the globe 12 is attached. An opening 11ba for attaching the globe 12 is formed through the attachment wall 11bb.

  Referring to FIGS. 2, 3 and 4, the globe 12 is made of a curved plate made of a light-transmitting material and has a shell-like configuration. 4 is a cross-sectional view taken along the line IV-IV of the illuminating lamp 10 of FIG. 3, and is a cross-sectional view passing through the center of the base housing 11 a and the cover 11 b and the center of the arm 3. Glass, resin, or the like can be used as the material constituting the globe 12. The globe 12 may have a contour with a convex curved surface such as a hemisphere, a semi-ellipsoid, a semi-cylindrical body, and a semi-elliptical cylinder. In the present embodiment, the globe 12 has a semi-ellipsoidal outline, that is, an outer shape. And the glove | globe 12 is engaged from the inner side of the housing | casing 11 with the periphery 12a with the periphery of opening part 11ba in the attachment wall part 11bb of the cover 11b, and protrudes from attachment wall part 11bb through opening part 11ba.

  Referring to FIG. 4, the illuminating lamp 10 supplies the light emitting unit 20 that emits light with the supplied power, the light emitting unit support 14 that supports the light emitting unit 20, and the light emitting unit 20 inside the housing 11. A power supply unit 15 that controls electric power and a power supply unit support 13 that supports the power supply unit 15 are provided.

  The base housing 11a integrally has a support wall portion 11aa therein. The base housing 11a and the support wall portion 11aa may be configured to be integrally formed from one continuous member, and may be formed from separate members so that the support wall portion 11aa is attached to the base housing 11a. May be configured. The support wall portion 11aa is made of the same material as that of the base housing 11a, and is made of a flat plate as a whole with some bending. The support wall portion 11aa also has thermal conductivity. The support wall portion 11aa is located at a position facing the attachment wall portion 11bb and the opening portion 11ba of the cover 11b that closes the base housing 11a, and extends along the attachment wall portion 11bb. The support wall 11aa is formed in a shape and dimensions that include the entire projected image of the opening 11ba when the opening 11ba is projected onto the support wall 11aa in a direction substantially perpendicular to the support wall 11aa.

  Referring to FIGS. 4 and 5, the power source support 13 is disposed on the surface of the support wall 11aa on the opening 11ba side in the housing 11. 5 is a bottom view in which the cover 11b is removed from the illumination lamp 10 of FIG. The power supply support 13 integrally includes a substantially rectangular flat plate main body 13a and a flat support arm 13b that stands upright from each of two edges along the longitudinal direction of the main body 13a. ing. The main body 13a and the support arm 13b are integrally formed from a single continuous member. The support arm portions 13b are arranged substantially in parallel so that the wide flat surfaces face each other. That is, each support arm portion 13b is arranged with a wide flat surface in a direction along the longitudinal direction of the rectangular main body portion 13a. The main body 13a and the support arm 13b, that is, the power supply support 13 are made of a material having lower thermal conductivity than the material constituting the light emitting support 14 described later. Furthermore, it is more preferable that the power supply support 13 is made of a material having low thermal conductivity. For example, the power supply support 13 is preferably made of a material having heat retention or heat insulation such as stainless steel, zirconia, or resin.

  The main body 13a of the power supply support 13 is formed on the support wall 11aa so that its longitudinal direction is along the direction from the end 11ab through which the arm 3 of the base housing 11a passes to the end 11ac at which the hinge 11c is provided. It is arranged. The main body portion 13a extends substantially parallel to the support wall portion 11aa, and in particular, contacts the flat surface of the support wall portion 11aa on the end portion 11ac side and extends so as to follow the shape of the flat surface. . A part of the main body 13a on the end 11ac side is included in a projection image of the opening 11ba on the support wall 11aa. At this time, the support arm 13b is located at a position facing the opening 11ba and protrudes from the main body 13a toward the opening 11ba. In the present embodiment, the support arm portion 13b is included in the projection image of the opening portion 11ba to the support wall portion 11aa, although not limited to this. Therefore, the main body 13 a and the support arm 13 b are located at positions corresponding to the opening 11 ba and the globe 12.

  A flat light emitting unit support 14 is attached to the distal end of the support arm 13b with respect to the main body 13a. The light-emitting portion support 14 is made of a material having thermal conductivity, and is particularly preferably made of a metal material having high thermal conductivity such as aluminum, aluminum alloy, alumina, and magnesium alloy. The light emitting unit support 14 is supported by two support arms 13b. The light emitting unit support 14 may be attached to the support arm 13b by any method. For example, a joining method such as fastening such as screwing, fitting, adhesion, or welding may be used for the attachment.

  The light emitting unit support 14 is arranged such that the wide flat surfaces 14 a and 14 b extend along the direction along the opening 11 ba and the peripheral edge 12 a of the globe 12. The light emitting unit support 14 is disposed in the vicinity of the opening 11ba and the periphery 12a of the globe 12, and is preferably located at a position aligned with the periphery of the opening 11ba or the periphery 12a of the globe 12, and more preferably, the opening 11ba. It is located inside the globe 12 with respect to the peripheral edge. The flat light-emitting portion support 14 has a planar shape and dimensions that can be accommodated inside the opening 11ba, specifically, the inside of the peripheral edge 12a of the globe 12, and in this embodiment, the opening 11ba. And a dodecagonal planar shape that follows the peripheral edge 12 a of the globe 12. The light emitting unit support 14 preferably extends so as to cover as many regions as possible of the opening 11ba. Further, the light emitting unit support 14 is positioned so as to face the main body 13 a with a space from the main body 13 a of the power supply support 13. The light emitting unit support 14 is fixed to the support arm 13b on two opposing sides of the light emitting unit support 14 along the longitudinal direction of the main body 13a. A space 16 in which at least a part of the power supply unit 15 can be disposed is formed between the light emitting unit support 14 and the main body unit 13a as described above.

  On the surface 14a of the light emitting unit support 14 opposite to the main body 13a, one light emitting unit 20 is disposed at the approximate center of the surface 14a. The light emitting unit 20 includes a semiconductor light emitting element unit 21 having a circular planar shape and a lens body 22. In the semiconductor light emitting element section 21, a plurality of semiconductor light emitting elements (LEDs: Light Emitting Diodes) are gathered and arranged in a circular area. For example, a plurality of COB (Chip On Board) type semiconductor light emitting elements are gathered and arranged side by side. Specifically, the plurality of semiconductor light emitting elements are arranged side by side along the direction along the surface 14a. Therefore, one semiconductor light emitting element unit 21 can emit light having a high luminous flux value, that is, bright light. The semiconductor light emitting element unit 21 is attached to the light emitting unit support 14 so that heat exchange with the light emitting unit support 14 is possible. At this time, the semiconductor light emitting element unit 21 may be directly attached to the light emitting unit support 14 or may be attached to the light emitting unit support 14 via a heat transfer member. Since the semiconductor light emitting element can be thinly formed in the light emitting direction, that is, the direction perpendicular to the surface 14a, the semiconductor light emitting element portion 21 can be thinly formed in the direction perpendicular to the surface 14a.

  The lens body 22 is provided in the semiconductor light emitting element unit 21 so as to cover the entire semiconductor light emitting element unit 21. The lens body 22 is made from a material such as resin or glass having translucency. The lens body 22 distributes the light emitted from the semiconductor light emitting element unit 21 so as to diffuse radially on the surface 14a. The lens body 22 is located inside the globe 12. In particular, the lens body 22 is preferably positioned inside the globe 12 rather than the periphery of the opening 11ba or the periphery 12a of the globe 12.

  In the present embodiment, the lens body 22 has a shape obtained by dividing a columnar body obtained by rotating an ellipse around its longitudinal axis A into two sections along the longitudinal axis. It has a shape in which both end faces of the cylinder are isolated surfaces. The lens body 22 is arranged so that its flat surface faces the surface 14a and its convex curved surface protrudes from the surface 14a. Further, the lens body 22 is arranged with the longitudinal axis A in a direction substantially perpendicular to the direction from the end 11ab to the end 11ac of the base housing 11a. The lens body 22 as described above causes the light emitted from the semiconductor light emitting element portion 21 to be emitted in a direction from the end portion 11ab toward the end portion 11ac and in a direction opposite to the emitted light in a direction perpendicular to the above direction. Distribute to become stronger.

  Further, the light emitting unit support 14 extends so as to block the space inside the globe 12 and the space in the housing 11 located behind the light emitting unit support 14 with respect to the globe 12. It extends so as to block the portion 20 and the space behind the light emitting portion support 14. For this reason, a part of the light diffused by the lens body 22 irradiates the surface 14 a of the light emitting unit support 14. Therefore, it is preferable that the surface 14a of the light emitting unit support 14 is configured to reflect light that irradiates the surface 14a. When the light emitting unit support 14 is made of a material that can reflect a large amount of light, such as aluminum or an aluminum alloy, the surface 14a may not be processed, and polishing or the like may be performed to improve the reflectivity. The surface 14a may be processed. When the light emitting unit support 14 is made of a material that cannot reflect much of the light, a surface treatment such as formation of a reflective film on the surface 14a or application of a reflective paint may be performed.

  On the main body 13 a of the power supply support 13, the power supply 15 is disposed in contact with the main body 13 a. The power supply unit 15 converts AC power supplied from the power system into DC power, and controls the DC power to supply it to the semiconductor light emitting element unit 21 of the light emitting unit 20. The power supply unit 15 includes a power conversion device such as an AC / DC converter. The power supply unit 15 is disposed on the back surface 14 b side of the light emitting unit support 14 with respect to the globe 12. The power supply unit 15 is at least partially located in a region of a projection image obtained by projecting the opening 11ba and the globe 12 on the support wall 11aa and the main body 13a in a direction substantially perpendicular to the support wall 11aa and the main body 13a. It arrange | positions so that at least one part may be located in the back part of the light emission part support body 14. As shown in FIG. That is, the power supply unit 15 is arranged so that at least a part thereof is located in a region corresponding to the opening 11ba and the globe 12. Specifically, the power supply unit 15 is arranged so that at least a part thereof is located in the space 16 between the main body unit 13 a and the light emitting unit support 14. The power supply unit 15 is also located between the two support arm portions 13 b of the power supply unit support 13. Furthermore, the power supply unit 15 is close to the light emitting unit support 14, but is disposed at a distance from the light emitting unit support 14.

  The power supply unit 15 may be covered with an outer shell such as a cover made of a material having lower thermal conductivity than the material constituting the light emitting unit support 14. Further, the outer shell may be made of a material having low thermal conductivity, and may be made of a material having heat retaining properties or heat insulating properties such as stainless steel, zirconia, and resin.

  The power supply unit 15 is electrically connected to a terminal 17 disposed on the main body unit 13 a of the power supply unit support 13. Furthermore, an electric wire extending from the power system through the cylindrical arm 3 into the housing 11 is connected to the terminal 17. Thereby, AC power of the power system is supplied to the power supply unit 15. Since the illuminating lamp 10 includes the power supply unit 15, it is not necessary to provide a power supply unit on the arm 3 and the column 2.

  In the illumination lamp 10 as described above, when the semiconductor light emitting element portion 21 of the light emitting portion 20 emits light, the semiconductor light emitting element portion 21 also generates heat. The heat of the semiconductor light emitting element unit 21 is released into the globe 12 or is transmitted to the light emitting unit support 14. The heat of the light emitting unit support 14 is dissipated into the globe 12 and the housing 11 from the light emitting unit support 14 having a large heat radiation area. Since the globe 12 protrudes from the housing 11, the heat in the globe 12 can be released to the outside of the globe 12 and the housing 11 through the globe 12, and it is possible to suppress the heat from entering the housing 11.

  Further, the heat in the light emitting unit support 14 is suppressed from being transmitted to the power supply unit support 13 having a lower thermal conductivity than the light emitting unit support 14. Transmission to the unit 15 is also suppressed. In addition, since the power supply unit 15 is disposed with a gap from the light emitting unit support 14, the transmission of heat received by the power supply unit 15 from the light emitting unit support 14 is suppressed. Furthermore, when the power supply unit 15 is covered with an outer shell having lower thermal conductivity than the light emitting unit support 14, the transmission of heat received by the power supply unit 15 from the light emitting unit support 14 is further suppressed. Moreover, since the main body 13a of the power supply support 13 is interposed between the power supply 15 and the base housing 11a of the housing 11, the movement of heat between the power supply 15 and the housing 11 is suppressed. Thereby, even when the heat of the light emitting unit 20 is transmitted to the housing 11, the heat of the housing 11 is suppressed from being transmitted to the power supply unit 15.

  Further, since the lens body 22 is inside the globe 12 and the light emitting unit support 14 is in the vicinity of the opening 11ba of the cover 11b, most of the light emitted from the semiconductor light emitting element unit 21 through the lens body 22 is large. Irradiation toward the outside of the housing 11 through the globe 12. That is, the light escaping to the back of the light emitting unit support 14 in the housing 11 is reduced. In addition, when the surface 14a of the light emitting unit support 14 has a light reflection characteristic, even if light emitted through the lens body 22 irradiates the surface 14a, the irradiated light is reflected by the surface 14a. Then, the light is irradiated toward the outside of the housing 11 through the globe 12. Since the globe 12 forms a convex curved surface protruding from the housing 11, the light passing through the globe 12 can irradiate a wide range. As for the light emitted from the globe 12, the amount of light in the direction from the end 11ab to the end 11ac of the housing 11 and in the opposite direction is larger than the amount of light in the direction perpendicular to the above direction. Therefore, the illuminating lamp 10 oriented so that the end portion 11ac is on the side to be irradiated such as the road side can effectively illuminate the region to be illuminated.
