厚さが１ｍｍ以下の銅板１００の表面にプリント配線基板を高熱伝導接着剤等で張り付け、裏面は銅の地金のまま用いる。銅板は薄いほどよく０．６ｍｍが好ましく用いられる。
プリント配線基板には端子１０３があり、ロービーム用発光ダイオード（ＬＥＤ）１０２とハイビーム用発光ダイオード（ＬＥＤ）１０２が取り付けられている。
発光ダイオード（ＬＥＤ）は、一辺が５ｍｍ〜７ｍｍのものを利用した。５ｍｍ以下では、発光量が少なく、７ｍｍ以上では焦点がぼやけてくる。
また、ロービーム用発光ダイオード（ＬＥＤ）１０２のみ、点灯して前方を照らす時、下方向に行く光を遮るシェード１０５を設けることが好ましい。
本願発明において用いられるヒートパイプは、市販のものが用いられる。すなわち、ＬＥＤ基板を取り付ける部位は扁平体２０１であり、アルミニウム製口金に取りつける部位は円筒体２０２である銅製のヒートパイプであり、ヒートパイプの中には、焼結金属微粒子と循環媒体が充填され、循環媒体は水、アルコールが用いられている。ヒートパイプの扁平体部位の厚さは１ｍｍ〜３ｍｍ程度のものを選ぶ。
表面にプリント配線基板１０３を設けた銅板と銅製のヒートパイプは、金属紛体を混入した高熱伝導接着剤等で接着する。接着剤は、エポキシ系、イミド系のものが用いられる。
ＬＥＤ基板とヒートパイプの扁平体を挟持する放熱部品３００は、両端が半円柱で、半円柱と半円柱のほぼ中心部にＬＥＤが顔を出す窓３０３を有する板状中間部を有する放熱部品３０１と、もう一方の両端が半円柱で平板状中間部を有する放熱部品３０２で、ＬＥＤ基板付のヒートパイプの扁平体を挟み付けたとき、両端が円柱状になり、円柱の中心部にＬＥＤ基板付のヒートパイプの扁平体が収納できる溝をそれぞれの半円柱の円柱中心部に設けたＬＥＤ基板付ヒートパイプ扁平体部位を挟持するためのアルミニウム製の放熱部品で、ＬＥＤ基板付のヒートパイプの扁平体部位を挟持する。放熱部品３０１と、もう一方の両端が半円柱で平板状中間部を有する放熱部品３０２をネジで固定してＬＥＤ基板付のヒートパイプの扁平体を挟み付けることもできる。
本発明においては、放熱部品３００を用いない実施態様も可能である。
本発明のヒートパイプ冷却ダブル型高輝度ＬＥＤ前照灯においては、ハイビーム用とロービーム用の２個の発光ダイオードを直列につなぐことが望ましい。何故なら、直列回路の場合、LEDチップの数に関係なく、LEDチップ１個の電流値で点灯することができるので、発熱量が少ないのに対し、並列回路の場合、LEDチップの数だけ、チップ当たりの電流値が必要となってくるために複数のLEDチップを点灯さす場合、電流を多くしなければならず、発熱量も多くなるからである。
A printed wiring board is attached to the surface of a copper plate 100 having a thickness of 1 mm or less with a high thermal conductive adhesive or the like, and the back surface is used as a copper ingot. The thinner the copper plate is, the better 0.6 mm is preferably used.
The printed wiring board has a terminal 103 to which a low beam light emitting diode (LED) 102 and a high beam light emitting diode (LED) 102 are attached.
A light emitting diode (LED) having a side of 5 mm to 7 mm was used. If it is 5 mm or less, the amount of light emission is small, and if it is 7 mm or more, the focus is blurred.
Further, it is preferable that only the low-beam light emitting diode (LED) 102 is provided with a shade 105 that blocks light going downward when it is turned on to illuminate the front.
A commercially available heat pipe is used in the present invention. That is, the part to which the LED substrate is attached is a flat body 201, and the part to be attached to the aluminum base is a copper heat pipe which is a cylindrical body 202. The heat pipe is filled with sintered fine metal particles and a circulating medium. The circulation medium is water or alcohol. The thickness of the flat part of the heat pipe is selected to be about 1 mm to 3 mm.
The copper plate provided with the printed wiring board 103 on the surface and the copper heat pipe are bonded with a high thermal conductive adhesive mixed with metal powder. As the adhesive, an epoxy type or an imide type is used.
A heat dissipating component 300 that sandwiches a flat body of an LED substrate and a heat pipe is a heat dissipating component 301 having a plate-shaped intermediate portion that has a semi-cylinder at both ends and a window 303 through which the LED faces in the center of the semi-cylinder and the semi-cylinder. And when the other end of the heat pipe with LED board is sandwiched between the heat dissipating parts 302 having a flat intermediate portion with a semi-cylindrical both ends, both ends become cylindrical, and the LED board is in the center of the cylinder. This is a heat-dissipating part made of aluminum for sandwiching the flat part of the heat pipe with LED board provided with a groove that can accommodate the flat body of the attached heat pipe in the center of each semi-cylindrical cylinder.

In this invention, the embodiment which does not use the heat radiating component 300 is also possible.
In the heat pipe cooled double-type high-intensity LED headlamp of the present invention, it is desirable to connect two light emitting diodes for high beam and low beam in series. This is because in the case of a series circuit, it can be lit with the current value of one LED chip regardless of the number of LED chips, so the amount of heat generation is small, whereas in the case of a parallel circuit, only the number of LED chips, This is because when a plurality of LED chips are turned on because a current value per chip is required, the current must be increased and the amount of heat generated also increases.

厚さが１ｍｍ以下の銅板（１００）の表面にプリント配線基板を高熱伝導接着剤等で張り付け、裏面は銅の地金のまま用いる。銅板は薄いほどよく０．６ｍｍが好ましく用いられる。
プリント配線基板には端子（１０３）があり、ロービーム用発光ダイオード（１０２）とハイビーム用発光ダイオード（１０２）が取り付けられている。
発光ダイオードは、一辺が５ｍｍ〜７ｍｍのものを利用した。５ｍｍ以下では、発光量が少なく、７ｍｍ以上では焦点がぼやけてくる。
また、ロービーム用発光ダイオード（１０２）のみ、点灯して前方を照らす時、下方向に行く光を遮るシェード（１０５）を設けることが好ましい。
本願発明において用いられるヒートパイプは、市販のものが用いられる。すなわち、発光ダイオード基板を取り付ける部位は扁平体（２０１）であり、アルミニウム製口金に取りつける部位は円筒体（２０２）である銅製のヒートパイプであり、ヒートパイプの中には、焼結金属微粒子と循環媒体が充填され、循環媒体は水、アルコールが用いられている。ヒートパイプの扁平体部位の厚さは１ｍｍ〜３ｍｍ程度のものを選ぶ。

A printed wiring board is attached to the surface of a copper plate (100) having a thickness of 1 mm or less with a high heat conductive adhesive or the like, and the back surface is used as a copper ingot. The thinner the copper plate is, the better 0.6 mm is preferably used.
The printed wiring board has a terminal (103) to which a low beam light emitting diode (102) and a high beam light emitting diode (102) are attached.

The heat dissipating fins (503) provided on the first heat dissipating pedestal (500) are conceived to have a cylinder with slits in one direction, slits with vertical and horizontal directions, or slits with different widths. Any one is possible.
Moreover, since the heat radiation fin (602) provided in the second heat radiating base (600) is provided on one surface around the cylindrical portion and the appearance is also important, it is desirable that the heat radiation fins (602) are provided in an orderly manner, such as one with a changed slit width. . In short, it should be made so that the wind sent out by the motor with a fan placed in the second heat radiating pedestal cavity (603) can efficiently pass between the slits and cool the second heat radiating pedestal (600).
In the present invention, a metal paste may be used as necessary in order to increase thermal conductivity.
As the metal paste, gold paste, silver paste, copper paste, nickel paste and the like are known, but silver paste is preferable from the viewpoint of heat dissipation and economy. Examples of silver paste include CT212M, CT284R, CT285 (Kyocera Chemical Co., Ltd.), TB3300 series (Three Bond Co., Ltd.), and the like.
