본 고안의 조명램프의 반사경에 관한 것으로서, 좀 더 상세히는 반사경의 탈락이 방지되어 반사율이 높고 내구성이 양호한 새로운 구조의 조명램프 반사경에 관한 것이다.The present invention relates to a reflector of a lighting lamp of the present invention, and more particularly, to a reflector of a new lamp having a high reflectance and good durability, by preventing the reflector from falling off.

자동차의 전조등과 같은 조명램프에는 전구의 배면부에 대체로 포물면경과 같은 오목거울 형태의 반사경(reflector)이 부착된다. 이 반사경은 전구에서 발산되는 빛을 한방향으로 모으고 반사율 높여서 원하는 방향으로 빛을 강하게 투사하는 기능을 수행한다.Lighting lamps, such as the headlights of automobiles, are generally equipped with a concave mirror shaped reflector, such as a parabolic mirror, at the rear of the bulb. This reflector collects the light emitted from the bulb in one direction and raises the reflectance to strongly project the light in the desired direction.

종래의 자동차의 전조등에 사용되는 반사경은 대체로 우레탄수지나 에폭시수지, 폴리카보네이트수지 또는 기타의 수지를 투명하게 처리하여 성형제작된 반사경 성형체에 알루미늄 반사층을 증착등의 방법으로 도금처리하여 거울과 같은 반사경을 제작하게 된다. 그런데, 이러한 알루미늄 반사층은 빛의 반사율이 90%에 달하여 그 밝기가 밝은 반면, 피복층이 쉽게 탈락되는 문제점이 있다. 알루미늄층이 탈락되면 균등한 반사가 이루어지지 않아 투사광의 품질이나 조도를 저하시키게 된다. 한편, 반사층을 크롬으로 도금한 것은 쉽게 탈락되지 않아서 내구성은 양호하나 반사율이 상대적으로 낮다는 단점을 지니고 있다.Reflector used in the headlight of a conventional automobile is generally a reflector such as a mirror by plating an aluminum reflecting layer on a reflector molded body formed by transparently treating a urethane resin, an epoxy resin, a polycarbonate resin or other resin. Will be produced. However, the aluminum reflecting layer has a problem that the light reflectance reaches 90% and the brightness thereof is bright, but the coating layer is easily dropped. If the aluminum layer is dropped, even reflection is not achieved, thereby degrading the quality or illuminance of the projection light. On the other hand, the plating of the reflective layer with chromium does not easily fall off, so it has good durability but low reflectance.

본 고안은 전술한 바와같은 종래의 반사경의 문제점에 착안하여 제안된 것으로, 반사경의 탈락이 방지되어 내구성이 높고 반사율도 높은 새로운 구조의 조명램프의 반사경을 제공하고자 하는 것이다.The present invention has been proposed in view of the problems of the conventional reflector as described above, and is intended to provide a reflector of a lighting lamp having a new structure having high durability and high reflectivity by preventing the fall of the reflector.

본 고안에 따르면, 전면에 투광렌즈가 구비되고 배면에는 반사경이 형성되며, 내부에 전구나 기타 발광체가 구비된 조명램프에 있어서, 상기 반사경은 투명한 재질의 합성수지로 오목면 형태로 성형된 투명수지층의 외부면에 알루미늄 반사층을 피복하고, 상기 알루미늄 반사층이 외부면에는 합성수지보호층을 피복처리한 것을 특징으로 하는 조명램프의 반사경이 제공된다.According to the present invention, a light transmitting lens is provided on the front surface and a reflecting mirror is formed on the rear surface, and in the lamp having a light bulb or other light emitting body therein, the reflecting mirror is a transparent resin layer formed in a concave shape with a synthetic resin made of a transparent material. An outer surface of the aluminum reflecting layer is coated, and the outer reflecting mirror is provided with an illumination lamp, characterized in that the outer surface is coated with a synthetic resin protective layer.

이하에서 도면을 참조하여 본 고안의 바람직한 실시예를 설명한다. 제1도는 본 고안의 반사경을 자동차의 전조등에 적용한 경우를 보여주는 것으로서, 전조등(1)은 대체로 전면에 설치된 투광렌즈(2)와 그 배면에 설치되며 대략 포물면 형태로 오목하게 성형된 반사경(4)으로 구성되고, 그 내부에는 전구(3)가 반사경(4)에 삽입되고 접속단자(5)가 외부로 돌출된 형태를 취한다. 전조등의 종류에 따라 전구(3)대신 필라멘트가 직접 구비될 수 있다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention. FIG. 1 shows a case in which the reflector of the present invention is applied to a headlight of an automobile. The headlight 1 is generally provided with a floodlight lens 2 installed at the front side and a reflector mirror 4 formed in a concave shape in a substantially parabolic form. The light bulb 3 is inserted into the reflector 4 and the connection terminal 5 protrudes to the outside. Depending on the type of headlight, the filament may be provided directly instead of the bulb 3.

이러한 구조를 취하는 전조등에서 본 고안의 특징을 이루는 반사경(4)은 그 부분확대도에 도시된 바와같이, 투명한 재질로 오목면체 또는 포물면체 형태로 성형된 투명수지층(6)을 본체로 하여 이루어지고, 투명수지층(6)의 외부면에는 통상적인 알루미늄 반사층(7)이 증착이나 기타의 방법으로 피복처리된다. 이 알루미늄 반사층(7)은 전술한 바와같은 반사율은 높지만 쉽게 탈락되기 때문에 이러한 탈락을 방지하기 위해 알루미늄 반사층(7)의 외부에 보호수지층(8)을 피복처리한다. 이 보호수지층(8)은 알루미늄과의 부착성이 좋고 내구성이 양호한 적절한 합성수지로 코팅처리되는데, 그러한 수지의 바람직한 예로는 우레탄수지를 들 수 있다.Reflector 4, which is a feature of the present invention in a headlamp having such a structure, is made of a transparent resin layer 6 molded into a concave or parabolic form of a transparent material, as shown in a partial enlarged view thereof. On the outer surface of the transparent resin layer 6, a conventional aluminum reflecting layer 7 is coated by vapor deposition or other methods. Since the aluminum reflecting layer 7 has a high reflectance as described above but easily falls off, the protective resin layer 8 is coated on the outside of the aluminum reflecting layer 7 to prevent such dropping. The protective resin layer 8 is coated with a suitable synthetic resin having good adhesion with aluminum and good durability, and urethane resins are preferable examples of such resins.

이상에서 설명한 본 고안에 따르면, 반사율은 양호하나 탈락이 쉬운 알루미늄 반사층(7)을 우레탄수지와 같은 보호수지로 피복하여 보호함으로써 알루미늄층의 탈락이 방지되어, 양호한 품질을 오랜시간 유지할 수 있으므로 램프의 품질의 향상과 아울러 내구성의 개선을 도모할 수 있게 된다.According to the present invention described above, the aluminum reflecting layer 7 which has good reflectance but is easy to fall off is covered with a protective resin such as urethane resin to protect the aluminum layer from falling off, so that good quality can be maintained for a long time. In addition to improving quality, durability can be improved.
