本考案は上記に鑑みて、ソケットと、発光体を包蔵する放熱部とを分離して、発光量に応じた放熱部を広く自在に対応できる構造とした、自動車用ＬＥＤランプの提供をその目的とするものである。  SUMMARY OF THE INVENTION In view of the above, the present invention provides an automotive LED lamp having a structure in which a socket and a heat radiating part that encloses a light emitter are separated, and a heat radiating part corresponding to the amount of emitted light can be widely used. It is what.

本考案の請求項１に記載した自動車用ＬＥＤランプは、下方に偏平部を形成するソケットに発光電気回路を配設した基盤を保持させ、該基盤の上方にＬＥＤから成る発光体を配設し、該発光体のアノード側端子とカソード側端子を、それぞれ前記偏平部の前後面に渡って露出配設し、前記基盤の上方にキャップを被蓋して成る自動車用ＬＥＤランプにおいて、
前記キャップが、外周に多数の凹凸部を縦設した放熱筒と該放熱筒の上端に係着されるレンズとから成り、前記発光体が放熱筒の内周に係着される放熱盤に取着されるとともに、該放熱盤の上方に配設される反射盤から突出されて成る。
また、請求項２に記載した自動車用ＬＥＤランプは、請求項１に記載した自動車用ＬＥＤランプにおいて、前記放熱筒の外周に多数の対流空隙を配して放熱材を周設して成る。According to a first aspect of the present invention, there is provided an automotive LED lamp in which a base having a light emitting electric circuit is held in a socket that forms a flat portion below, and a light emitter made of LED is provided above the base. In the automotive LED lamp, the anode side terminal and the cathode side terminal of the luminous body are respectively exposed and disposed over the front and rear surfaces of the flat part, and a cap is covered above the base.
The cap is composed of a heat radiating tube having a large number of uneven portions on the outer periphery and a lens attached to the upper end of the heat radiating tube, and the light emitter is attached to a heat radiating plate attached to the inner periphery of the heat radiating tube. It is attached and protrudes from a reflector disposed above the heat sink.
According to a second aspect of the present invention, there is provided an automotive LED lamp according to the first aspect of the present invention, in which a large number of convection gaps are arranged on the outer periphery of the heat radiating tube so as to surround the heat radiation material.

本考案の自動車用ＬＥＤランプによれば、発光体を包蔵する放熱部をソケットに接合する構成であるから、発光体の発光量に対して適切な放熱材や放熱構造を選択でき、放熱処理の自由度が広範となり、耐久的に、かつ、省力的に提供できる効果がある。また、多数の凹凸部を外周に縦設した放熱筒の外周に放熱材を周設した場合は、放熱筒と放熱材との間に対流が発現し、放熱速度が増す一方で放熱材による熱放散も早まって放熱効果が一層顕著となる。  According to the LED lamp for automobiles of the present invention, since the heat radiating portion that encloses the light emitter is joined to the socket, it is possible to select an appropriate heat dissipating material and heat dissipating structure with respect to the light emission amount of the light emitter. There is an effect that the degree of freedom is wide and can be provided in a durable and labor-saving manner. In addition, when a heat dissipating material is provided on the outer periphery of a heat radiating cylinder having a large number of irregularities arranged on the outer periphery, convection occurs between the heat radiating cylinder and the heat radiating material, increasing the heat dissipation speed while increasing the heat generated by the heat radiating material. The radiation effect is also accelerated and the heat dissipation effect becomes more remarkable.

本考案における放熱筒と放熱盤はそれぞれアルミニウム材のほか銅材も選択され、放熱筒の外周に形成される多数の凹凸部は三角形状や円弧形状などによる。また、放熱筒の外周に周設される放熱材は放熱シリコーンゴムや黒鉛（グラファイト）シートなどであり、発光電気回路も当然に発熱抑制回路（発光体としてのＬＥＤを１秒間に２００回点滅させるなど）が構成される。なお、反射盤を配設する関係では、レンズの内面を凸状に形成することは、ＬＥＤの指向性の幅を広くできる点で好ましい。  In the present invention, the heat radiating cylinder and the heat radiating board are each made of copper as well as aluminum, and the many irregularities formed on the outer periphery of the radiating cylinder are triangular or arcuate. The heat dissipating material provided around the outer periphery of the heat radiating cylinder is a heat radiating silicone rubber, graphite (graphite) sheet or the like, and the light emitting electric circuit naturally also has a heat generation suppressing circuit (LED as a light emitter blinks 200 times per second). Etc.) are configured. In terms of the arrangement of the reflector, it is preferable that the inner surface of the lens is formed in a convex shape because the width of directivity of the LED can be widened.

本考案の自動車用ＬＥＤランプＡを実施例により説明すると、図１に示すように、下方に偏平部１ａを形成し、上方に丸座状の保持座１ｂを配設し、保持座１ｂの上部にそれよりやや直径を縮径した嵌着部１ｃを設け、偏平部１ａの前後の偏平面１ｄに面する保持座１ｂの絞り部には放熱口１ｅを開口して成る合成樹脂製のソケット１に対して、アルミニウム材から成る放熱筒２ａが図２に示すように、前記嵌着部１ｃに外嵌されるとともに、保持座１ｂの段差部に着座され、該嵌着部１ｃの上端には、図７に示す発光電気回路３を配設した基盤４が係着され、放熱筒２ａの内周に突出させた突出座２ｂの下端には中央に光量の増大されたハイパーＬＥＤから成る発光体５が係着されたアルミニウム材の放熱盤２ｄが位置決め係止され、放熱盤２ｄの上面には反射盤６が発光体５をのぞかせて着座され、放熱筒２ａの上端には合成樹脂製のレンズ７がその縮径部を内嵌する状態で被蓋され、発光体５のアノード側接点５ａとカソード側接点５ｂのそれぞれは、発光電気回路３を経て２本のアノード側端子４ａａとカソード側端子４ｂｂに接続され、両端子４ａａ、４ｂｂは偏平部１ａを通ってその下端からそれぞれ左右において、前後の偏平面１ｄに折曲配設される。
そして、放熱筒２ａの外周には図３に示すように、多数の三角形状の凹凸部２ｃが縦設される。このように、上記放熱筒２ａ、突出座２ｂ、凹凸部２ｃ、放熱盤２ｄが放熱部２を形成する。
前記のアノード側端子４ａａとカソード側端子４ｂｂは図５（ｂ）に示すように、基盤４の裏面に配設された電気部品に接続され、表面には図５（ａ）に示すように、それぞれ前記アノード側端子４ａａとカソード側端子４ｂｂとに接続されたアノード側リード線４ａとカソード側リード線４ｂがその一端を接続され、他端は図４に示すように、それぞれ放熱盤２ｄに取着されたハイパーＬＥＤから成る発光体５のアノード側接点５ａとカソード側接点５ｂにリード板５ｃを介して接続される。An automotive LED lamp A according to the present invention will be described with reference to an embodiment. As shown in FIG. 1, a flat portion 1a is formed below, a round seat-shaped holding seat 1b is disposed above, and an upper portion of the holding seat 1b is formed. The socket 1 made of a synthetic resin is provided with a fitting portion 1c having a slightly smaller diameter than that, and a heat radiating port 1e opened in the throttle portion of the holding seat 1b facing the flat surface 1d before and after the flat portion 1a. On the other hand, as shown in FIG. 2, the heat radiating cylinder 2a made of an aluminum material is externally fitted to the fitting portion 1c and is seated on the step portion of the holding seat 1b. 7, a light emitting body comprising a hyper LED having a light quantity increased in the center at the lower end of a projecting seat 2b projecting to the inner periphery of the heat radiating cylinder 2a. The heat sink 2d made of aluminum, to which 5 is attached, is positioned and locked to dissipate heat. A reflector 6 is seated on the upper surface of 2d with the light emitter 5 being looked over, and a synthetic resin lens 7 is covered on the upper end of the heat radiating cylinder 2a with the reduced diameter portion fitted therein. Each of the anode-side contact 5a and the cathode-side contact 5b is connected to the two anode-side terminals 4aa and the cathode-side terminal 4bb via the light emitting electric circuit 3, and both the terminals 4aa and 4bb pass through the flat portion 1a from the lower end thereof. In each of the left and right sides, the front and rear flat surfaces 1d are bent.
And as shown in FIG. 3, many triangular uneven | corrugated | grooved parts 2c are provided in the outer periphery of the thermal radiation cylinder 2a vertically. Thus, the heat radiating cylinder 2a, the projecting seat 2b, the uneven portion 2c, and the heat sink 2d form the heat radiating portion 2.
The anode side terminal 4aa and the cathode side terminal 4bb are connected to electrical components disposed on the back surface of the base 4 as shown in FIG. 5 (b), and on the surface as shown in FIG. 5 (a), One end of each of the anode side lead wire 4a and the cathode side lead wire 4b connected to the anode side terminal 4aa and the cathode side terminal 4bb is connected to the anode side terminal 4aa and the cathode side terminal 4bb, and the other end is connected to the heat sink 2d as shown in FIG. The anode-side contact 5a and the cathode-side contact 5b of the light emitter 5 made of the attached hyper LED are connected via a lead plate 5c.

また、図６に示すように、自動車用ＬＥＤランプＡにおいて、放熱筒２ａの外周には放熱シリコーンゴムや黒鉛シートなどによる放熱材８が多数の対流空隙９を配して周設される自動車用ＬＥＤランプＢも提供される。
この実施例では、ほぼ三角形状の多数の凹部が対流空隙９を形成するものであり、放熱筒２ａからの放熱によって対流が発現して放熱速度が増し、同時に周設される放熱材８に熱伝導されて放熱が早まり、より一層放熱効果が顕著となる。
このように、ソケット１の材質とは別個の材質で放熱部２を形成するから、発光量に対応して放熱部２の構成を選択できることとなって、省力的に耐久性の向上を図ることができる。なお、図７に示した発光電気回路３は、ハイパーＬＥＤから成る発光体５を１秒間に２００回点滅させる点滅回路を組み込み、発光体５を保護し、より明るく見せるための工夫を内蔵するものである。Further, as shown in FIG. 6, in the automotive LED lamp A, the heat radiating material 8 made of heat radiating silicone rubber, graphite sheet or the like is provided around the heat radiating cylinder 2a with a large number of convection gaps 9 disposed around it. An LED lamp B is also provided.
In this embodiment, a large number of substantially triangular recesses form the convection gap 9, and convection is generated by heat radiation from the heat radiating cylinder 2 a, thereby increasing the heat radiation speed. Conduction accelerates heat dissipation, and the heat dissipation effect becomes even more pronounced.
Thus, since the heat radiation part 2 is formed of a material different from the material of the socket 1, the configuration of the heat radiation part 2 can be selected in accordance with the amount of light emission, and the durability can be improved in a labor-saving manner. Can do.
