Description

本願発明は既存の白熱電球、ミニ電球、クリプトン電球、ボール型電球、レフランプ型電球、ハロゲンランプ、ビームランプといった各種電球やランプと同様の形状で、それらに代えて使用できるLED照明具に関する。   The present invention relates to an LED illuminator that has the same shape as various light bulbs and lamps such as existing incandescent light bulbs, mini light bulbs, krypton light bulbs, ball type light bulbs, reflex lamp type light bulbs, halogen lamps, and beam lamps.

近年、既存の白熱電球、ハロゲンランプ、各種口金付き電球に代わって、省電力、長寿命といった長所を有するLEDを用いたLED電球が開発され普及し始めている。LEDは前記長所を有する一方で放熱量が多いという難点があるため、LEDを用いた照明具には放熱対策が施されている。放熱対策が施されたLED照明具として、LED光源及び電源回路等の周囲を筒状の放熱カバーで囲ったもの(特許文献1)や、口金の先にラッパ状に広がる金属製の放熱カバー(ヒートシンク)を設け、そのヒートシンク内にLED光源を設けたもの(特許文献2)等がある。   In recent years, instead of existing incandescent bulbs, halogen lamps, and bulbs with various caps, LED bulbs using LEDs having advantages such as power saving and long life have been developed and are beginning to spread. While LED has the above-mentioned advantages, it has a drawback that it has a large amount of heat dissipation, and therefore, a lighting tool using LED is provided with a heat dissipation measure. As LED lighting fixtures with heat dissipation measures, the LED light source and power supply circuit are surrounded by a cylindrical heat dissipation cover (Patent Document 1), or a metal heat dissipation cover that spreads in a trumpet shape at the end of the base ( A heat sink) and an LED light source provided in the heat sink (Patent Document 2).

(1)特許文献1、2記載のLED照明具は、金属製のヒートシンクが口金とバルブの間に配置されているため、LEDからの照明光はヒートシンクの周囲には出射されず、バルブの先だけしか照明されない。このため照明エリアが狭い、ヒートシンクの形状が特殊であるため電球全体の形状が特殊になり、用途が限られるといった難点がある。これまでの白熱電球を見慣れた人にとっては形状に違和感があるといった難点がある。
(2)特許文献1、2のいずれに記載のLED照明具も、ヒートシンクの外面温度が高温になるため、手が触れると火傷をするおそれがある。また、ヒートシンクからの放熱で照明具の周囲が昇温し易い。
(3)特許文献1、2のいずれに記載のLED照明具もヒートシンクが大型であるため、電球が従来の電球に比して大型であり、ヒートシンクがアルミダイキャスト製であるため重い。
(1) In the LED lighting devices described in Patent Documents 1 and 2, since the metal heat sink is disposed between the base and the bulb, the illumination light from the LED is not emitted around the heat sink, and the tip of the bulb Only is illuminated. For this reason, since the illumination area is narrow and the shape of the heat sink is special, the shape of the entire bulb is special, and there is a problem that the application is limited. For those who are familiar with incandescent lamps, there is a problem that the shape is uncomfortable.
(2) The LED illuminator described in any of Patent Documents 1 and 2 may be burned when touched by a hand because the outer surface temperature of the heat sink becomes high. In addition, the temperature around the lighting fixture easily rises due to heat radiation from the heat sink.
(3) Since the LED illuminator described in Patent Documents 1 and 2 has a large heat sink, the light bulb is larger than a conventional light bulb and is heavy because the heat sink is made of aluminum die cast.

本願発明の課題は、前記諸問題を解決でき、省電力、長寿命というLEDの長所を生かしつつ、大型のヒートシンクを設けなくとも効率良く放熱でき、放熱体の外表面が昇温しにくく、火傷する危険が少なく、従来のLED照明具に比して照明エリアが広く、小型化できるLED照明具を提供することにある。   The object of the present invention is to solve the above problems, take advantage of LED power saving and long life, and efficiently dissipate without providing a large heat sink.

An endothermic fin is provided, a circuit board is accommodated inside a cylindrical radiator, a base is mounted on the radiator, an LED is mounted on the radiator, and the radiator is made of high thermal conductivity carbon fiber.

本願発明のLED照明具は、前記LED照明具において、放熱体の先端側に、LEDからの光を反射させる反射ミラーが設けられ、その反射ミラーは略椀型のミラー本体の内面が内側反射面、外面が凹凸の外側反射面であり、底の部分にLEDを配置可能なLED配置孔があり、そのLED配置孔の周面がLEDからの光が入射可能な入射面であり、前記内側反射面は前記LED配置孔から進入するLEDからの光を反射させ、前記外側反射面は前記入射面から入射してミラー本体の肉厚内を進むLEDからの光が乱反射して外側反射面の外側に出射するようにしてある。 In the LED lighting device of the present invention, in the LED lighting device, a reflection mirror that reflects light from the LED is provided on the front end side of the radiator, and the inner surface of the substantially bowl-shaped mirror body is the inner reflection surface. The outer surface is an uneven outer reflection surface, and there is an LED arrangement hole in which the LED can be arranged at the bottom, and the peripheral surface of the LED arrangement hole is an incident surface on which light from the LED can enter, and the inner reflection The surface reflects light from the LED entering from the LED arrangement hole , and the outer reflective surface is incident on the incident surface and diffuses light from the LED that travels within the thickness of the mirror body, and is outside the outer reflective surface. It is made to radiate | emit to.

本願発明のLED照明具は次のような効果がある。
(1)放熱体が高熱伝導率の炭素繊維を含む樹脂製であるため放熱性に優れ、放熱体を小型化しても放熱ができ、従来のヒートシンクのような大型の放熱体を必要としないため、この放熱体を従来のハロゲンランプのベースの代用として、或いは既存のLED電球のヒートシンクの代用として使用すれば、照明具を小型化することができる。
(2)LEDからの光が放熱体で遮光されずバルブの側方も照明され、照射範囲が広角になる。火傷をするおそれがない。
(3)高熱伝導率の炭素繊維を含む樹脂製の放熱体の外周を、導電性絶縁材で被覆したため、放熱体が導電性であっても漏電の危険性がなく、しかも、放熱性も確保されるため、前記(2)記載の効果が確保される。
(4)放熱体の内周面に吸熱フィンを設けたので、放熱体の内表面積が広くなり、LEDや電源回路から発生する熱が吸熱され易くなり、吸熱された熱が放熱体を通して外部に放熱されるので、放熱体を小型化しても放熱性に優れ、照明具を小型化できる。
(5)回路基板が放熱体の内側空間内に収容されているので、LED照明具の形状もサイズも小型化でき、従来のフィラメント式の電球やハロゲンランプ等とほとんど同じにすることができ、大型化せず違和感もない。
(6)放熱体の外周面に放熱用フィンを設けたので、より一層放熱性が向上する。
(7)LED用電源回路に過電流切断器(例えばヒューズ)を設けたので、電源回路に定格以上の電流(過電流)が流れることがなく、電源回路やLEDが損傷せず長寿命になり、放熱体が異常に高熱になることもないので発火の危険を回避することもできる。
(8)回路基板が放熱体の内部空間内に縦向きに配置されているので、放熱体の内部空間を有効活用でき、回路基板を設けるスペースを別途設ける必要がないので小型化できる。
(9)バルブ内にLEDからの光を出射方向先方に導光する透光性レンズを設けたので、LEDからの光がレンズを通して効率よく先方に導光される。また、レンズ外周面からも出射されるのでLEDからの光が直進性であってもバルブの側方も照明され照射範囲が広がる。
(10)反射ミラーの内面が内側反射面、外面が凹凸の外側反射面であり、底の部分にLEDを配置可能なLED配置孔があり、そのLED配置孔の周面がLEDからの光が入射可能な入射面であり、前記内側反射面は前記LED配置孔から進入するLEDからの光を反射させ、前記外側反射面は前記入射面から入射してミラー本体の肉厚内を進むLEDからの光が乱反射して外側反射面の外側に出射するようにしてあるので、反射ミラーの内側が照明されるのみでなく、反射ミラーの外周面も照明されて明るくなる。LED光は直進性であるため従来の反射ミラーではその外周面を照明することはできなかった。
L ED lighting fixture of the present invention has the following effects.
(1) Since the radiator is made of resin containing carbon fiber with high thermal conductivity, it has excellent heat dissipation, and even if the radiator is reduced in size, it can dissipate heat and does not require a large radiator such as a conventional heat sink. If this heat radiator is used as a substitute for a conventional halogen lamp base or as a substitute for a heat sink of an existing LED bulb, the illuminator can be miniaturized.
(2) The light from the LED is not shielded by the heat radiating body, and the side of the bulb is illuminated, and the irradiation range becomes a wide angle. There is no risk of burns.
(3) Since the outer periphery of a resin heat sink containing carbon fiber with high thermal conductivity is covered with a conductive insulating material, there is no risk of leakage even if the heat sink is conductive, and heat dissipation is also ensured. Therefore, the effect described in (2) is ensured.
(4) Since the heat sink is provided on the inner peripheral surface of the radiator, the inner surface area of the radiator is increased, the heat generated from the LED and the power supply circuit is easily absorbed, and the absorbed heat is transferred to the outside through the radiator. Since the heat is radiated, even if the heat radiator is reduced in size, the heat dissipation is excellent, and the lighting fixture can be reduced in size.
(5) Since the circuit board is housed in the inner space of the radiator, the shape and size of the LED illuminator can be reduced, and it can be made almost the same as a conventional filament type bulb or halogen lamp, There is no sense of incongruity without upsizing.
(6) Since the heat dissipating fins are provided on the outer peripheral surface of the heat dissipating body, the heat dissipation is further improved.
(7) Since the LED power supply circuit is provided with an overcurrent disconnector (for example, a fuse), no current (overcurrent) exceeding the rated value will flow in the power supply circuit, and the power supply circuit and LED will not be damaged, resulting in a long service life. Since the heat radiator does not become abnormally hot, the risk of ignition can be avoided.
(8) Since the circuit board is disposed vertically in the internal space of the heat radiating body, the internal space of the heat radiating body can be used effectively, and it is not necessary to separately provide a space for providing the circuit board, thereby reducing the size.
(9) Since the translucent lens for guiding the light from the LED in the emission direction is provided in the bulb, the light from the LED is efficiently guided to the front through the lens. Moreover, since it is radiate | emitted also from a lens outer peripheral surface, even if the light from LED is a rectilinear advance, the side of a bulb | ball is illuminated and the irradiation range spreads.
(10) The inner surface of the reflection mirror is an inner reflection surface, the outer surface is an uneven outer reflection surface, and there is an LED arrangement hole in which the LED can be arranged at the bottom, and the peripheral surface of the LED arrangement hole receives light from the LED. The incident surface is an incident surface, the inner reflection surface reflects light from the LED entering from the LED arrangement hole , and the outer reflection surface is incident from the incident surface and travels within the thickness of the mirror body. Is diffusely reflected and emitted to the outside of the outer reflecting surface, so that not only the inner side of the reflecting mirror is illuminated, but also the outer peripheral surface of the reflecting mirror is illuminated and brightened. Since the LED light is straight, the conventional reflecting mirror cannot illuminate the outer peripheral surface.

(LED lighting tool 1)
The LED illuminator of the present invention uses LEDs as a light source and has various shapes and structures such as a screw-type base, a two-pin type base, and a one-touch type base that can be attached to and detached from an existing light bulb socket. It is equipped with electrical connectors that can be attached to and detached from sockets, ceilings, rosettes, adapters, receptacles, etc. (hereinafter these bases and electrical connectors are collectively referred to as “bases”). Although the thing of the various shape of a type | mold is included, what is shown in FIG. 1 as an example of embodiment is a halogen lamp type LED lighting fixture.

図1に示すLED照明具は、放熱体1の下に、電球用ソケットに脱着可能な口金類2を備え、放熱体1の先端(図1では上)に反射ミラー3を備え、光源にLED4(図2)が使用され、そのLED4を搭載したLED用基板5が前記放熱体1の受部6の上に搭載され、放熱体1の内部空間7(図3)内にLED4の動作(発光)に必要な電源回路やその他の電気回路、電子部品等を備えた回路基板(プリント基板や積層基板等)8(図2)が縦向きに収容配置されている。前記回路基板8は上方開口の筒型の保持具9(図2)内に縦向きに収容され、その保持具9を図4のように放熱体1の内部空間7に収容することにより内部空間7に収容されている。   The LED illuminator shown in FIG. 1 includes a base 2 that can be attached to and detached from a socket for a light bulb under a radiator 1, a reflection mirror 3 at the tip of the radiator 1 (upper in FIG. 1), and an LED 4 as a light source. (FIG. 2) is used, the LED substrate 5 on which the LED 4 is mounted is mounted on the receiving portion 6 of the radiator 1, and the operation (light emission) of the LED 4 in the internal space 7 (FIG. 3) of the radiator 1 is used. A circuit board (printed board, laminated board or the like) 8 (FIG. 2) provided with a power supply circuit, other electric circuits, electronic parts, etc. necessary for the above is accommodated and arranged vertically. The circuit board 8 is accommodated vertically in a cylindrical holder 9 (FIG. 2) having an upper opening, and the internal space 7 is accommodated by accommodating the holder 9 in the internal space 7 of the radiator 1 as shown in FIG. 7 is housed.

図1の放熱体1は従前のハロゲンランプのベースの代用とすることができる。図1の口金類2は既存のハロゲンランプの口金と同様にJIS規格で定められているE11口金であり、従来のハロゲンランプが脱着されていたソケットに脱着可能なものである。本願発明の口金類2は図7(a)に示すような2ピンタイプのものとか、図7(b)に示すようなワンタッチ型のもの、その他の形状、構造のものであってもよい。   The heat radiator 1 of FIG. 1 can be used as a substitute for the base of a conventional halogen lamp. A base 2 shown in FIG. 1 is an E11 base defined by the JIS standard in the same manner as a base of an existing halogen lamp, and can be attached to and detached from a socket from which a conventional halogen lamp is attached and detached. The base 2 of the present invention may be a two-pin type as shown in FIG. 7 (a), a one-touch type as shown in FIG. 7 (b), or other shapes and structures.

前記放熱体1は放熱性(伝熱性)に優れた樹脂製であり、図2に示すように上方が受部(LED搭載部)6で閉塞され、図3に示すように下方が開口された円筒状であり、周壁1a(図3)の外周面に細長の凹溝10が多数本設けられ、それら凹溝10の間に多数本の突条の放熱フィン11が設けられている。また、周壁1aの内周面には細長突条の吸熱フィン12が突設されている。それら吸熱フィン12は周壁1aの内周面の対向位置に2本平行に設けられ、隣接する2本の吸熱フィン12の間に嵌合溝13が形成されている。前記受部6(図2)には回路基板8(図2)から導出されているリード線14を差込み可能な差込み孔15が開口されている。吸熱フィン12の本数や形状等は図示したものに限られず、放熱体1の内周面の面積を広くすることができれば、他の本数、形状等にすることができる。ここで吸熱とはLEDや電源回路等から放出される熱が放熱体1に伝達されることである。このように、放熱体1の内周面から伝達された熱(吸熱)が放熱体1の外周面に伝導されてその外周面から外部に放熱される。放熱フィン11、吸熱フィン12は他の形状、本数、間隔とすることができ、それらを設ける箇所も図示した放熱体1の外周面、内周面の所望箇所とすることができる。   The heat radiating body 1 is made of a resin excellent in heat dissipation (heat conductivity), and the upper part is closed by a receiving part (LED mounting part) 6 as shown in FIG. 2, and the lower part is opened as shown in FIG. A plurality of elongated grooves 10 are provided on the outer peripheral surface of the peripheral wall 1 a (FIG. 3), and a plurality of protruding radiating fins 11 are provided between the grooves 10. Further, an elongated heat absorbing fin 12 projects from the inner peripheral surface of the peripheral wall 1a. Two endothermic fins 12 are provided in parallel at opposite positions on the inner peripheral surface of the peripheral wall 1 a, and a fitting groove 13 is formed between two adjacent endothermic fins 12. The receiving portion 6 (FIG. 2) has an insertion hole 15 into which the lead wire 14 led out from the circuit board 8 (FIG. 2) can be inserted. The number, shape, and the like of the heat-absorbing fins 12 are not limited to those shown in the drawings, and other numbers, shapes, and the like can be used as long as the area of the inner peripheral surface of the radiator 1 can be increased. Here, the heat absorption means that heat released from the LED, the power supply circuit, or the like is transmitted to the radiator 1. Thus, the heat (heat absorption) transmitted from the inner peripheral surface of the radiator 1 is conducted to the outer peripheral surface of the radiator 1 and is radiated to the outside from the outer peripheral surface. The heat dissipating fins 11 and the heat absorbing fins 12 can have other shapes, numbers, and intervals, and the locations where they are provided can also be the desired locations on the outer peripheral surface and inner peripheral surface of the radiator 1 illustrated.

前記放熱体1の成型用樹脂には、熱伝導率を高めた放熱樹脂、例えば、成型用樹脂中に熱伝導性フィラー材料を適量分散混合した樹脂が適する。熱伝導性フィラーとしては、アルミナ、窒化ホウ素、窒化アルミニウム、シリカ等の無機フィラー、銀、金、銅などの金属フィラー、高熱伝導性の炭素系フィラーなどが好ましい。これらの中でも、樹脂の熱伝導率を最も効率的に高め、機械的強度や成形性にも高い性能が得られる高結晶性の黒鉛構造を有する黒鉛化炭素繊維が好ましく、特に、メソフェーズピッチを原料とし、平均繊維径が2〜20μm、平均繊維長が30〜1000μm、黒鉛結晶の六角網面の成長方向に由来する結晶子サイズが20nm以上である黒鉛化炭素短繊維が好ましい。平均繊維径はより好ましくは5〜15μm、平均繊維長はより好ましくは70〜300μm、結晶子サイズはより好ましくは40nm程度である。   As the molding resin of the heat radiating body 1, a heat radiating resin having an increased thermal conductivity, for example, a resin in which an appropriate amount of a heat conductive filler material is dispersed and mixed in the molding resin is suitable. As the heat conductive filler, inorganic fillers such as alumina, boron nitride, aluminum nitride and silica, metal fillers such as silver, gold and copper, carbon fillers having high heat conductivity and the like are preferable. Among these, graphitized carbon fibers having a highly crystalline graphite structure that can increase the thermal conductivity of the resin most efficiently and obtain high performance in mechanical strength and moldability are preferable, and mesophase pitch is particularly used as a raw material. Graphite carbon short fibers having an average fiber diameter of 2 to 20 μm, an average fiber length of 30 to 1000 μm, and a crystallite size derived from the growth direction of the hexagonal network surface of the graphite crystal are preferably 20 nm or more. The average fiber diameter is more preferably 5 to 15 μm, the average fiber length is more preferably 70 to 300 μm, and the crystallite size is more preferably about 40 nm.

黒鉛化炭素短繊維に関する商品としては、例えば帝人株式会社製のラヒーマ(登録商標:以下同じ)が挙げられる。これら黒鉛化炭素繊維を各種成形樹脂中に適量割合、例えば、10〜50wt%程度の割合で分散混合することが好ましい。   Examples of the products related to the graphitized carbon short fibers include Lahima (registered trademark: the same applies hereinafter) manufactured by Teijin Limited. These graphitized carbon fibers are preferably dispersed and mixed in various molding resins at an appropriate ratio, for example, about 10 to 50 wt%.

熱伝導性フィラーは複数種を組み合わせて利用することも可能であり、黒鉛化炭素繊維と無機フィラー及び/又は金属フィラーを組み合わせて利用する事も好ましく行われる。前記組み合わせは適量で行われるが、熱伝導フィラーをトータル30〜60wt%前後の割合で樹脂に混合した場合、放熱樹脂の熱伝導率として20W/m・K以上の高い値を得ることも可能である。マトリックスとする樹脂材料としては、各種の熱可塑性樹脂、熱硬化性樹脂が好ましく用いられ、射出成形、プレス成形、ブロー成形、真空成形、注型法などの成形法により、放熱性に優れた放熱体1を成型することができる。   It is also possible to use a combination of a plurality of heat conductive fillers, and it is also preferable to use a combination of graphitized carbon fiber and an inorganic filler and / or a metal filler. The above combination is performed in an appropriate amount, but when the heat conductive filler is mixed with the resin at a ratio of about 30 to 60 wt% in total, it is also possible to obtain a high value of 20 W / m · K or higher as the heat conductivity of the heat radiation resin. is there. As the resin material for the matrix, various thermoplastic resins and thermosetting resins are preferably used, and heat dissipation with excellent heat dissipation is achieved by molding methods such as injection molding, press molding, blow molding, vacuum molding, and casting. The body 1 can be molded.

熱可塑性樹脂としては、例えばポリエチレン、ポリプロピレン、ポリカーボネート、ポリブチレンテレフタレート、ポリフェニレンスルフィド、脂肪族ポリアミド(ナイロン)、ポリエーテルエーテルケトン、液晶ポリマー(LCP)等が挙げられ、これらのアロイ、変性体等も利用可能である。変性物としてはエラストマー成分を共重合してなる熱可塑性エラストマー等も好適に用いられる。   Examples of the thermoplastic resin include polyethylene, polypropylene, polycarbonate, polybutylene terephthalate, polyphenylene sulfide, aliphatic polyamide (nylon), polyether ether ketone, liquid crystal polymer (LCP), etc., and alloys and modified products thereof.

本願発明の放熱体1は、その全面(外面、内周面、端面の全て)或いは外面又は外面と端面(外から手の触れる箇所)に絶縁被膜を施して絶縁性を確保することができる。ちなみに、放熱体1は、前記黒鉛化炭素繊維が混合された樹脂製の場合は導電性があるため、絶縁被膜を施さないと、放熱体1に手が触れると導通して感電するおそれがあるが、絶縁被膜を設けることにより、その危険性が解消される。絶縁被膜は電着塗装とか他の手法で施すことができる。絶縁被膜する絶縁塗料は絶縁性(耐電圧特性)があるだけでなく、放熱性のあるものが望ましく、更には、耐熱性のあるものがより一層望ましい。その一例としては株式会社シミズのエレコート(放熱/絶縁電着塗料)がある。エレコートにはポリイミドタイプ、フッ素系タイプ、フォトレジタイプ、装飾タイプ等各種のものがあるが、本願発明ではそれらのいずれも使用可能である。絶縁塗料は色彩のあるものでも良く、その場合は、放熱体1を着色することができる。   The heat dissipating body 1 of the present invention can ensure insulation by applying an insulating film to the entire surface (all of the outer surface, inner peripheral surface, and end surface), or the outer surface or the outer surface and the end surface (where the hand touches from the outside). Incidentally, since the heat radiator 1 is conductive when it is made of a resin mixed with the graphitized carbon fiber, there is a risk of electric conduction when the hand touches the heat radiator 1 unless an insulating film is applied. However, the danger is eliminated by providing the insulating coating. The insulating coating can be applied by electrodeposition coating or other methods. The insulating coating for the insulating coating is not only insulative (withstand voltage characteristics), but also preferably has heat dissipation properties, and more preferably has heat resistance properties. One example is Shimizu Corporation's Elecoat (heat dissipation / insulating electrodeposition paint). There are various types of Elecoat such as polyimide type, fluorine type, photoresist type, and decorative type, and any of them can be used in the present invention. The insulating paint may be colored, and in that case, the radiator 1 can be colored.
