Description
【０００１】[0001]
本考案は、光源バルブから発生する熱から灯具のハウジングを保護する遮熱構 造を備えた車両用灯具の改良に関する。 The present invention relates to an improvement of a vehicular lamp including a heat shield structure that protects a housing of the lamp from heat generated by a light source bulb.
【０００２】[0002]
意匠上の設計要求から薄型化、偏平化された車両用灯具にあっては、樹脂等で 形成される灯具のハウジングをバルブの発生熱から保護するため、ハウジングの 内側面に金属板等の遮熱板を設けた灯具が提案されている。 In vehicular lamps that have been made thinner and flattened due to design requirements, in order to protect the housing of the lamp made of resin or the like from the heat generated by the bulb, the inner surface of the housing is shielded from metal plates, etc. A lamp provided with a heating plate has been proposed.
【０００３】[0003]
遮熱板を設けた灯具では、バルブで発生した熱は遮熱板で反射されるため、そ れなりの遮熱効果が得られるが、遮熱板自体がある程度の熱をもつと、ハウジン グ側に熱を放出（輻射）するようになるので、ハウジングをバルブの発生熱から 確実に保護することは難しい。 In a lamp equipped with a heat shield plate, the heat generated by the bulb is reflected by the heat shield plate, so a corresponding heat shield effect can be obtained, but if the heat shield plate itself has a certain amount of heat, it will Since heat is released (radiated) to the side, it is difficult to reliably protect the housing from the heat generated by the valve.
【０００４】[0004]
本考案は、遮熱板による遮熱効果を充分に発揮させることができる遮熱構造を 有する車両用灯具を提供することを目的としている。 An object of the present invention is to provide a vehicular lamp having a heat shield structure capable of sufficiently exerting the heat shield effect of the heat shield plate.
【０００５】[0005]
本考案は、ハウジングを光源バルブの発生熱から保護するための遮熱体をハウ ジングから所要の間隔をとって配設し、ハウジングの遮熱体対向面を熱反射面に 形成し、遮熱体のハウジング対向面を熱吸収面に形成したことを要旨としている 。 In the present invention, a heat shield for protecting the housing from the heat generated by the light source bulb is arranged at a required distance from the housing, and the surface of the housing facing the heat shield is formed as a heat reflection surface, so that the heat shield is formed. The gist is that the surface of the body facing the housing is formed as a heat absorption surface.
【０００６】[0006]
上記構成によれば、遮熱体自体が熱をもっても、ハウジングから離隔している ので、熱の放出によるハウジングへの影響は少ない。また、遮熱体から熱の放出 があっても、その放出熱はハウジングの熱反射面で反射され、遮熱体の熱吸収面 に吸収されるので、ハウジングの遮熱作用はより一層高められる。 According to the above configuration, even if the heat shield itself has heat, it is separated from the housing, so that the heat release does not affect the housing. Further, even if heat is released from the heat shield, the released heat is reflected by the heat reflection surface of the housing and absorbed by the heat absorption surface of the heat shield, so that the heat shield effect of the housing is further enhanced. .
【０００７】[0007]
図１〜図２に、本考案の一実施例を示す。 同図において、１は灯具を形成している合成樹脂製ハウジング、２は前面レン ズ、３は光源バルブである。４はハウジングを保護するための金属製遮熱体であ り、図示の例では、ハウジング１の上側部分、底側部分および後側部分と対向す るように箱形に作られている。５ａ，５ｂはハウジングと一体に設けられた断面 Ｌ形で対をなす溝部であり、箱形の遮熱体４は、その縁辺に形成した突出爪４ａ を溝部５ａ，５ｂにそれぞれ挿し込むことにより、溝部に保持されるようになっ ている。 1 and 2 show an embodiment of the present invention. In the figure, 1 is a synthetic resin housing forming a lamp, 2 is a front lens, and 3 is a light source bulb. Reference numeral 4 denotes a metal heat shield for protecting the housing, and in the illustrated example, it is formed in a box shape so as to face the upper portion, the bottom portion and the rear portion of the housing 1. Reference numerals 5a and 5b are groove portions that are integrally formed with the housing and that form a pair with an L-shaped cross section. It is designed to be held in the groove.
【０００８】 ハウジング１には、箱形遮熱体４と対向する上側部分、底側部分および後側部 分に突起部１ａが一体に突出されており、前記遮熱体４は前記突起部１ａにより ハウジング内面から所定の間隔をとって位置づけされている。The housing 1 is integrally provided with a protrusion 1 a at an upper portion, a bottom portion and a rear portion facing the box-shaped heat shield 4, and the heat shield 4 has the protrusion 1 a. Are positioned at a predetermined distance from the inner surface of the housing.
【０００９】 そして、前記ハウジング１の遮熱体対向面には、銀色等の塗装による熱反射面 ６が形成され、遮熱体４のハウジング対向面には黒色等の塗装による熱吸収面７ が形成されている。A heat-reflecting surface 6 made of silver or the like is formed on the surface of the housing 1 facing the heat shield, and a heat absorbing surface 7 made of black or the like is formed on the surface of the heat shield 4 facing the housing. Has been formed.
【００１０】 上記構成によれば、遮熱体４が熱をもっても、ハウジング１から離隔されてい るので、熱の放出によるハウジングへの影響は少ない。また、遮熱から熱の放出 があっても、その放出熱はハウジング内面の熱反射面６で反射され、それが遮熱 体４の熱吸収面７で吸収されるので、ハウジングの遮熱作用はより一層高められ る。According to the above configuration, even if the heat shield 4 is heated, it is separated from the housing 1, so that the influence of the heat release on the housing is small. Further, even if heat is released from the heat shield, the released heat is reflected by the heat reflection surface 6 on the inner surface of the housing and is absorbed by the heat absorption surface 7 of the heat shield 4, so that the heat shield effect of the housing is obtained. Is further enhanced.
【００１１】 なお、遮熱体４をハウジング１内で保持する手段や遮熱体４をハウジング１か ら離隔する手段は、図示の例に限定されるものでなく、他の手段を適宜に採用す ることができる。The means for holding the heat shield 4 in the housing 1 and the means for separating the heat shield 4 from the housing 1 are not limited to the illustrated example, and other means are appropriately adopted. can do.
【００１２】[0012]
以上説明したように、本考案によれば、遮熱体をハウジングから離隔させ、ハ ウジングの遮熱体対向面に熱反射面を設け、遮熱体のハウジング対向面に熱吸収 面を設けて構成したので、従来の遮熱構造に較べ、その遮熱効果を格段と高める ことができる。 As described above, according to the present invention, the heat shield is separated from the housing, the heat reflecting surface is provided on the housing facing surface of the heat shield, and the heat absorbing surface is provided on the housing facing surface of the heat shield. Since it is configured, its heat shield effect can be significantly enhanced compared to the conventional heat shield structure.
