Description

本発明は、ＬＥＤ光源を用いたフォグランプ等の車両用ランプであって、レンズの曇りや結露を防止した車両用ランプに関するものである。   The present invention relates to a vehicular lamp such as a fog lamp using an LED light source, which prevents fogging or condensation of a lens.

従来よりレンズの曇りを抑制した車両用灯具が知られている（特許文献１）。
この車両用灯具は、図４に示すように、キセノンランプなどのフィラメントを発光させる光源ランプ２と、この光源ランプ２を収容するランプハウジング３と、このランプハウジング３を遮蔽するインナーハウジング４と、前記光源ランプ２の光を拡幅するインナーレンズ５と、このインナーレンズ５を通過した光を拡幅するアウターレンズ６を具備している。また、車両用灯具１は、アウターレンズ６の内側に空気層を形成するための空気室Ｑを有する。この空気室Ｑがインナーレンズ５及びアウターレンズ６を含む複数の部材により区画されてなる準密封空間であり、かつ、空気室Ｑに乾燥空気が封入されている。なお、Ｐは、灯室であり、Ｒは、閉空間である。 Conventionally, a vehicular lamp that suppresses fogging of a lens is known (Patent Document 1).
As shown in FIG. 4, the vehicular lamp includes a light source lamp 2 that emits a filament such as a xenon lamp, a lamp housing 3 that houses the light source lamp 2, an inner housing 4 that shields the lamp housing 3, An inner lens 5 for widening the light of the light source lamp 2 and an outer lens 6 for widening the light passing through the inner lens 5 are provided. Further, the vehicular lamp 1 has an air chamber Q for forming an air layer inside the outer lens 6. The air chamber Q is a semi-sealed space defined by a plurality of members including the inner lens 5 and the outer lens 6, and the air chamber Q is filled with dry air. In addition, P is a lamp chamber and R is a closed space.

特開２００８−７１５７４号公報。Japanese Patent Application Laid-Open No. 2008-71574.

特許文献１に記載の発明は、光源ランプ２がメタルハライドランプなどの高圧金属蒸気放電灯、高輝度放電灯（ＨＩＤ）、ハロゲンランプ、白熱電球など、フィラメントで発光する電球を用いて構成されている。
この種ランプの結露は、ランプ内と外気に温度差が生じ、かつ、湿気があり、露点になると発生する。
しかるに、フィラメントで発光する電球は、発光後、発熱によりすぐに高温になり、一時的に結露してもすぐに消滅し、外気温度に左右されないので露点になりにくい。
これに対し、光源がＬＥＤの場合には、ＬＥＤの発熱があっても灯具内部の温度がゆっくりと上昇するので、灯具内の温度と湿度により露点になり一旦結露が生じると曇りの状態が長引きなかなか消滅しにくい。
特許文献１に記載の発明は、インナーレンズ５とアウターレンズ６の間に空気室Ｑを形成し乾燥空気を封入しているが、この従来の灯具のフィラメントで発光する電球に代えてＬＥＤを使用した場合、すぐに高温にならないので、露点状態が継続してしまうという問題があった。 In the invention described in Patent Document 1, the light source lamp 2 is configured using a light bulb that emits light with a filament, such as a high-pressure metal vapor discharge lamp such as a metal halide lamp, a high-intensity discharge lamp (HID), a halogen lamp, or an incandescent lamp. .
Condensation of this type of lamp occurs when there is a temperature difference between the inside and outside air of the lamp, and there is moisture and the dew point is reached.
However, a light bulb that emits light with a filament immediately becomes high temperature due to heat generation after light emission, and immediately disappears even if dew is temporarily formed, and since it does not depend on the outside air temperature, it does not easily become a dew point.
On the other hand, when the light source is an LED, the temperature inside the lamp rises slowly even if the LED generates heat, so the dew point is caused by the temperature and humidity inside the lamp, and once dew condensation occurs, the cloudy state is prolonged. It is hard to disappear.
In the invention described in Patent Document 1, an air chamber Q is formed between the inner lens 5 and the outer lens 6 to enclose dry air, but an LED is used instead of a light bulb that emits light with the filament of this conventional lamp. In such a case, there is a problem that the dew point state continues because the temperature does not immediately rise.

本発明は、ＬＥＤ光源を使用した車両用ランプにおいて、灯具内が露点になりにくいものを提供することを目的とするものである。   An object of the present invention is to provide a vehicle lamp using an LED light source that is less likely to have a dew point inside the lamp.
