Description
本発明のヘッドライトバルブユニットは、前部にヘッドライトの光源として発光ダイオードを備えるヒートパイプと、前記ヒートパイプの後部に連結部材を介して結合されている銅線からなるリボン形状の可撓導体であるヒートシンクとを有する。The headlight bulb unit of the present invention is a ribbon-shaped flexible conductor comprising a heat pipe having a light emitting diode as a light source of a headlight at the front, and a copper wire coupled to the rear of the heat pipe via a connecting member. And a heat sink.
上記の構成においては、ヒートパイプの前部に位置する発光ダイオードより発せられた熱は、ヒートパイプの熱伝導作用により、ヒートパイプ後部側のヒートシンクへ速やかに移動する。そして、ヒートシンクに移った熱は、そこで滞留を生じることなく、リボン形状のヒートシンクの輪の中を移動し、効果的に放熱される。また、ヒートシンクがリボン形状の可撓導体であり屈曲性能が良いため、本ヘッドライトバルブユニットをヘッドライトハウジングに容易に収めることができる。In said structure, the heat emitted from the light emitting diode located in the front part of a heat pipe moves rapidly to the heat sink of the heat pipe rear side by the heat conduction effect | action of a heat pipe. Then, the heat transferred to the heat sink moves through the ribbon-shaped heat sink ring without causing stagnation there, and is effectively dissipated. Further, since the heat sink is a ribbon-shaped flexible conductor and has good bending performance, the headlight bulb unit can be easily accommodated in the headlight housing.
本発明の好適な一態様によれば、ヒートパイプは、銅のパイプで構成され、この銅パイプに所定の液体（たとえば水またはアセトン）を封入し、銅パイプの内部を真空にしている。According to a preferred aspect of the present invention, the heat pipe is composed of a copper pipe, and a predetermined liquid (for example, water or acetone) is sealed in the copper pipe, and the inside of the copper pipe is evacuated.
別の好適な一態様によれば、ヒートシンクは、銅線を編んだ織物状のシートを輪にし、その輪の中央部を固定部材により挟まれる構成により、リボン形状を成している。According to another preferred embodiment, the heat sink is formed in a ribbon shape by a configuration in which a woven fabric sheet knitted with copper wire is used as a ring, and a center part of the ring is sandwiched between fixing members.
別の好適な一態様においては、ヒートパイプの後部は、ヒートシンクの中央部を貫通する上記連結部材とそれを固定する固定部材とによって、ヒートシンクに固定される。In another preferred embodiment, the rear portion of the heat pipe is fixed to the heat sink by the connecting member penetrating the central portion of the heat sink and the fixing member for fixing the connecting member.
別の好適な一態様においては、上記ヒートパイプの前部に取り付けられる温度センサーと、この温度センサーの感知する温度が基準温度に達すると自動的に減光する（電力を絞る）コントローラーとが更に備えられる。In another preferred embodiment, a temperature sensor attached to the front portion of the heat pipe, and a controller that automatically dims (thresholds power) when the temperature sensed by the temperature sensor reaches a reference temperature are further included. Provided.
図２に、ヘッドライトランプ２の全体を示す。ヘッドライトランプ２は発熱部を有するヒートパイプ４と放熱機能を持つヒートシンク５からなり、ヒートパイプ４の前部はＬＥＤ基板７とＬＥＤチップ８を有し、ヒートパイプ４の後部はヒートシンク５中央部を貫く連結部材１０とそれを固定する固定部材１１でヒートシンク５に固定される。 Figure 2 shows the overall headlight lamp 2. Headlight lamp 2 consists heat sink 5 with a heat pipe 4 and the heat dissipation function having a heat generating portion, front portion of the heat pipe 4 has an LED substrate 7 and the LED chips 8, section after the heat pipes 4 the heat sink 5 central portion It is fixed to the heat sink 5 by a connecting member 10 penetrating through and a fixing member 11 for fixing it.
ヒートパイプ４の目的は熱を速く移動させることにあるため、銅そのものよりも薄い銅からなるパイプを用いることが望ましく、ヒートパイプ４内部に関しては水が回りやすい配置が望まれる。それにより、放熱部であるヒートシンク５と発熱部であるヒートパイプ４の前部との温度差を４℃以下とすることができる。 Since the purpose of the heat pipe 4 is to move heat quickly, it is desirable to use a pipe made of copper that is thinner than copper itself. Thereby, it is possible to make the temperature difference between the front portion of the heat pipe 4 is exothermic part heat sink 5 is a heat radiating portion and 4 ° C. or less.
また、アルミ板と可撓導体６をほぼ同じ特性にするには、可撓導体６の厚さをアルミ板の厚さの８割程度に換算すればよく、可撓導体６の厚さを１．５ｍｍとすれば、２ｍｍのアルミ板とほぼ同一の特性となる。そして、それをリボン形状にすることにより、表面積が広く、屈曲性能を持った放熱部となる。なお、可撓導体６の厚さを決定する換算率は、使う素材の線径により異なり、これは断面積比率によることとなる。 Further, in the flexible conductor 6 and the aluminum plate at approximately the same characteristics, the thickness of the flexible conductor 6 may be converted to about 80% of the thickness of the aluminum plate, the thickness of the flexible conductor 61 If it is .5 mm, it has almost the same characteristics as a 2 mm aluminum plate. And by making it a ribbon shape, it becomes a heat radiating part with a large surface area and bending performance. In addition, the conversion factor which determines the thickness of the flexible conductor 6 changes with the wire diameters of the raw material to be used, and this is based on a cross-sectional area ratio.
