Description

本考案は放熱性に優れ、簡単な構造で組み立てることができるＬＥＤ電球に関する考案である。   The present invention relates to an LED bulb that is excellent in heat dissipation and can be assembled with a simple structure.

近年、省エネルギー照明としてＬＥＤ電球が普及している。ＬＥＤ電球は、発光ダイオードから発生する熱を効果的に放熱し点灯回路の温度上昇を抑制することと、より安価に提供することが課題となっている。
従来、ＬＥＤ電球の放熱構造として、特許文献１に開示されるように給電構造である口金の先方に位置する本体の外表面に放熱フィンを形成することや、特許文献２に開示されるように本体の外表面に凹凸を形成する思想が開示されている。 In recent years, LED bulbs have become widespread as energy-saving lighting. LED bulbs have a problem of effectively dissipating the heat generated from the light emitting diodes to suppress the temperature rise of the lighting circuit and providing it at a lower cost.
Conventionally, as disclosed in Patent Document 1, as a heat dissipation structure of an LED bulb, a heat radiation fin is formed on the outer surface of a main body located at the tip of a base that is a power feeding structure, or as disclosed in Patent Document 2. The idea of forming irregularities on the outer surface of the main body is disclosed.

特許文献３には、本体をアウトハウジングとインナーハウジングで形成し、インナーハウジングに放熱フィンを形成し、アウトハウジングに通し孔を穿設する方熱構造が開示されている。 Patent Document 3 discloses a heat-generating structure in which a main body is formed of an out housing and an inner housing, heat radiating fins are formed in the inner housing, and a through hole is formed in the out housing.

特開２０１０−５６０５９号公報JP 2010-56059 A 特開２０１１−３４９５８号公報JP 2011-34958 A 実用新案登録第３１６４８１７号公報Utility Model Registration No. 3164817

特許文献１や２に開示される思想は、本体構造として複雑なフィン構造や、凹凸構造を成型する必用があり、本体からの自然放熱であるため電球内部の温度を必ずしも効果的に冷却することができるものではなかった。
また、特許文献３に開示された構造では、本体そのものを二重構造とする複雑な構造であって、アウトハウジングに通し孔が露出するものであった。したがって、従来のＬＥＤ電球は必ずしも安価に供給されるものではなかった。 The idea disclosed in Patent Documents 1 and 2 requires that a complex fin structure or a concavo-convex structure be molded as the main body structure, and because it is natural heat dissipation from the main body, the temperature inside the bulb is necessarily cooled effectively. It was not something that could be done.
Further, the structure disclosed in Patent Document 3 is a complicated structure in which the main body itself has a double structure, and the through hole is exposed in the out housing. Therefore, the conventional LED bulb is not necessarily supplied at a low cost.

また、本体１にＬＥＤ基板４を組み立てる場合、給電筒２内のリード線15といった給電手段をＬＥＤ基板４に電気的に接続するとともに、ＬＥＤ基板４を台座７の先端面にビスなどで固定するだけで、組立が完了する。すなわち、ＬＥＤ基板の取付け構造を簡略化することができ、全体として少ない部品点数でＬＥＤ電球を構成することができる。 According to the first aspect of the present invention, the heat generated in the light emitting diode 8 is transmitted to the pedestal 7 formed integrally with the main body 1, and the air gap is formed in the gap 9 formed between the pedestal 7 and the power feeding cylinder 2. In addition, since the heated air is discharged outside the device, there is an effect of effectively radiating heat. Of course, the heat transmitted to the main body 1 through the pedestal 7 is also partially dissipated from the surface of the main body 1.

以下、本考案に係るＬＥＤ電球の実施形態を、添付の図面に基づいて説明する。
本考案に係るＬＥＤ電球は、図１に示すように基端に口金３を備えた給電筒２と、熱伝導性に優れた材質、例えばアルミニュウムもしくはアルミニュウム合金で一体成型をする筒状の本体１と、筒状の本体１の先方部分に配置するＬＥＤ基板４と、本体１の先方部分を覆う透光性を有するグローブ５とで構成している。 Hereinafter, embodiments of an LED bulb according to the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 1, an LED bulb according to the present invention includes a power supply tube 2 having a base 3 at a base end, and a cylindrical main body 1 integrally formed of a material having excellent heat conductivity, for example, aluminum or an aluminum alloy. And the LED substrate 4 disposed in the front portion of the cylindrical main body 1 and the translucent globe 5 covering the front portion of the main body 1.

給電筒２は、合成樹脂材によって一体成型し、基端部外周に一方の電極となる口金３をインサート成型するとともに、基端中心部に他方の電極14を配置している。口金３及び電極14からは、リード線15、15を先方（図１の上方）へ引き出してＬＥＤ基板４に接続し、ＬＥＤ基板４上の発光ダイオード８を発光させるようにしている。ＬＥＤ基板４は、アルミニュウム製の板状の取付け台13に固定し、このアルミニュウム製の取付け台13を、本体１の台座７の先端面にビス16、16によって密接状態に固定している。   The power supply cylinder 2 is integrally formed of a synthetic resin material, and a base 3 serving as one electrode is insert-molded on the outer periphery of the base end portion, and the other electrode 14 is disposed at the center portion of the base end portion. From the base 3 and the electrode 14, lead wires 15 and 15 are pulled out (upward in FIG. 1) and connected to the LED substrate 4 so that the light emitting diode 8 on the LED substrate 4 emits light. The LED board 4 is fixed to an aluminum plate-like mounting base 13, and the aluminum mounting base 13 is fixed in close contact with the distal end surface of the base 7 of the main body 1 with screws 16 and 16.

熱伝導性に優れたアルミニュウム材で一体成型をする筒状の本体１は、図２に示すように軸方向中心位置に給電筒２を収容することができる給電筒収容空間６を形成し、先方に向けてラッパ状に拡径する筒状としている。ラッパ状に拡径する本体１の内部には、給電筒収容空間６と本体１内周面の間に軸方向に連続する台座７を本体１と一体に形成している。図示実施形態では、台座７とともに軸方向に連続する放熱リブ10を本体１と一体に形成している。   As shown in FIG. 2, a cylindrical main body 1 integrally molded with an aluminum material having excellent thermal conductivity forms a feeding cylinder housing space 6 that can accommodate the feeding cylinder 2 at the axial center position. It is set as the cylinder shape which expands in a trumpet shape toward. A pedestal 7 that is continuous in the axial direction is formed integrally with the main body 1 between the feeding tube housing space 6 and the inner peripheral surface of the main body 1 inside the main body 1 that expands in a trumpet shape. In the illustrated embodiment, a heat radiating rib 10 that is continuous with the base 7 in the axial direction is formed integrally with the main body 1.

図示例の台座７及び放熱リブ10は、平面形状を一つの頂点が外周方向に向く略五角形とし、台座７及び放熱リブ10の内周辺の組み合わせによって、略円形断面の給電筒２を収容することができる給電筒収容空間６を形成している。台座７と放熱リブ10の違いは、台座７が略五角形の中実状態で軸方向に連続するものであるのに対して、放熱リブ10は略五角形の中空状態で軸方向に連続させていることである。台座７の先端面には、ＬＥＤ基板４、具体的には取付け台13を固定するためのビス孔17、17、を穿設している。   The pedestal 7 and the heat radiating rib 10 in the illustrated example have a planar shape with a substantially pentagonal shape with one vertex facing the outer peripheral direction, and the power supply cylinder 2 having a substantially circular cross section is accommodated by a combination of the inner periphery of the pedestal 7 and the heat radiating rib 10. The feed tube accommodating space 6 is formed. The difference between the pedestal 7 and the radiating rib 10 is that the pedestal 7 is continuous in the axial direction in a substantially pentagonal solid state, whereas the radiating rib 10 is continuous in the axial direction in a substantially pentagonal hollow state. That is. Screw holes 17, 17 for fixing the LED substrate 4, specifically, the mounting base 13, are formed in the tip surface of the base 7.

給電筒収容空間６を形成する台座７の内面と、給電筒２の外周面の間には、通気路となる隙間９を保持している。この、隙間９は本体１の基部において外部に開口させている。通気路となる隙間９は、台座７の内面と給電筒２の外周面の全周にわたって形成するものであってもよいが、図示実施形態では、台座７及び放熱リブ10の内周面を給電筒２の外周面に当接もしくは近接させて、給電筒２を安定状態で収容することができるようにしている。そして、台座７の内周面に軸方向に連続する溝11を設けるとともに、放熱リブ10の内周面には軸方向に連続し、中空部分に連通する一定幅の開放部18を形成している。   A gap 9 serving as a ventilation path is held between the inner surface of the pedestal 7 that forms the feeding tube housing space 6 and the outer peripheral surface of the feeding tube 2. The gap 9 is opened to the outside at the base of the main body 1. The gap 9 serving as a ventilation path may be formed over the entire inner surface of the pedestal 7 and the outer peripheral surface of the power supply cylinder 2, but in the illustrated embodiment, the inner peripheral surfaces of the pedestal 7 and the heat radiating rib 10 are fed. The power supply tube 2 can be accommodated in a stable state by contacting or approaching the outer peripheral surface of the tube 2. Then, an axially continuous groove 11 is provided on the inner peripheral surface of the pedestal 7, and an open portion 18 having a constant width is formed on the inner peripheral surface of the heat radiating rib 10 so as to communicate with the hollow portion in the axial direction. Yes.

上記構成とすることによって、組み立てた状態において台座７の内周面に軸方向に連続する溝11によって通気路となる隙間９が形成される。また、放熱リブ10の内周面に開放部18が形成されていることによって放熱リブ10の中空部分を空気が流通し本体１内における放熱効果を助長する。   By setting it as the said structure, the clearance gap 9 used as an air flow path is formed in the inner peripheral surface of the base 7 by the groove | channel 11 continuous in an axial direction in the assembled state. Further, since the open portion 18 is formed on the inner peripheral surface of the heat radiating rib 10, air flows through the hollow portion of the heat radiating rib 10 and promotes the heat radiating effect in the main body 1.

以上述べた、ＬＥＤ電球は、予めリード線15、15をＬＥＤ基板４に接続した状態で給電筒２を本体１の給電筒収容空間６に挿入して本体１に係止させ、ＬＥＤ基板４の取付け台13をビス16によって、本体１の台座７の先端面に密接状態で固定する。本体１の先端部には、透光性を有するグローブ５を装着することによって組立が完了する。   In the LED bulb described above, the lead tube 15 is inserted into the feed tube housing space 6 of the main body 1 in a state where the lead wires 15 and 15 are connected to the LED substrate 4 in advance. The mounting base 13 is fixed in close contact with the distal end surface of the base 7 of the main body 1 with screws 16. Assembling is completed by attaching a translucent glove 5 to the tip of the main body 1.

図４は、本考案に係るＬＥＤ電球を下向けに位置させて点灯した使用状態を示す断面図である。この状態では、発光ダイオード８において発生した熱は、図面上矢印で示すように、ＬＥＤ基板４や取付け台13を介して主として台座７や放熱リブ10に伝わり、台座７に伝わった熱によって暖められた空気は、隙間９を通って本体１の基端部に形成された開口部分から器外に放出される。隙間９は狭いものであるが、ＬＥＤ電球は下向きに使用されることが多く、このような状態では煙突の効果によって隙間９の開口部分から熱せられた空気が放出され、効果的に放熱（冷却）される。勿論、本体１の外表面からも大気中に放熱されると同時に、放熱リブ10に伝わった熱は、本体１の内部において空気との接触面積が増大する結果放熱の効果が助長される。   FIG. 4 is a cross-sectional view illustrating a use state in which an LED bulb according to the present invention is positioned downward and turned on. In this state, the heat generated in the light emitting diode 8 is mainly transmitted to the pedestal 7 and the heat radiating rib 10 via the LED substrate 4 and the mounting base 13 as indicated by arrows in the drawing, and is warmed by the heat transmitted to the pedestal 7. The air passes through the gap 9 and is released from the opening formed at the base end of the main body 1 to the outside. Although the gap 9 is narrow, LED bulbs are often used downward, and in such a state, heated air is released from the opening of the gap 9 due to the effect of the chimney, effectively dissipating heat (cooling). ) Of course, heat is also radiated from the outer surface of the main body 1 to the atmosphere, and at the same time, the heat transmitted to the heat radiating rib 10 increases the contact area with the air inside the main body 1, thereby promoting the effect of heat dissipation.

図５、図６に示す実施形態は、隣接する台座７及び放熱リブ10を連続壁12によって連続させたものである。このように、隣接する台座７及び放熱リブ10を連続させることによって、給電筒収容空間６を全体として筒状とし、構造的に安定した丈夫なものとすることができる。図５に示す実施形態は、連続壁12を台座７の内周面位置よりも少し外方に形成し、台座７と放熱リブ10の間にも通気路となる隙間が形成されるようにしている。   In the embodiment shown in FIGS. 5 and 6, adjacent pedestals 7 and heat radiating ribs 10 are made continuous by a continuous wall 12. In this way, by connecting the adjacent pedestals 7 and the heat radiating ribs 10 in a continuous manner, the power feeding cylinder accommodating space 6 can be made cylindrical as a whole, and can be structurally stable and strong. In the embodiment shown in FIG. 5, the continuous wall 12 is formed slightly outward from the position of the inner peripheral surface of the pedestal 7 so that a gap serving as a ventilation path is also formed between the pedestal 7 and the heat radiating rib 10. Yes.

図６は、図５に示す実施形態の電球の使用状態を示す断面図であり、図面上矢印で示すように、給電筒２の外周面と台座７の内周面、あるいは台座７と放熱リブ10の間に形成された隙間９を通過して熱せられた空気が本体１の基部から器外に放出され、効果的に放熱される。
放熱リブ10は中空状であり、軸方向に連続する開放部18が形成されているため、伝わった熱によって熱せられた空気は、放熱リブ10の中空部分を通過して器外に放出され、効果的に冷却される。 FIG. 6 is a cross-sectional view showing a use state of the light bulb of the embodiment shown in FIG. 5, and as indicated by arrows on the drawing, the outer peripheral surface of the power supply tube 2 and the inner peripheral surface of the base 7, or the base 7 and the heat radiating rib. The air heated by passing through the gap 9 formed between 10 is discharged from the base of the main body 1 to the outside of the device, and is effectively dissipated.
Since the heat dissipating rib 10 is hollow and has an open portion 18 that is continuous in the axial direction, the air heated by the transmitted heat passes through the hollow portion of the heat dissipating rib 10 and is released to the outside. Effectively cooled.
