본 발명은 광을 포함하는 에너지가 전송, 반사 또는 흡수될 수 있는 핫 프레싱에 의한 제작되는 알루미늄 거울에 관한 것이다. The present invention relates to an aluminum mirror fabricated by hot pressing in which energy containing light can be transmitted, reflected or absorbed.

건축용 윈도우, 스카이라이트 및 기타 대규모의 복합거울 제조시 실용적으로 사용되는 복합거울 및 그 제조방법은 복합거울을 형성하는 반사물질층 및 기타 물질층과의 연속적인 복합 또는 조합이 요구된다.  Composite mirrors and methods of manufacturing them practically used in the manufacture of architectural windows, skylights and other large-scale composite mirrors require continuous compounding or combination with reflective and other material layers forming the composite mirror.

따라서 복합거울의 형성을 위해 종래기술은 사실상 실용 가능한 장치를 제공할 수 없었다. 또한 거울 형성방법에 있어서, 그 제조공정은 부착층의 두께 및 그 화학조성의 증착이 불균일하고 대량 생산시 수율이 낮고, 광범위한 유지의 필요성이 요구되는 단점으로 인하여 대규모의 복합거울에 있어서 제작비용이 많이 드는 단점이 있었다. Thus, the prior art could not provide a practical device for the formation of a composite mirror. In addition, in the method of forming a mirror, the manufacturing process has a high manufacturing cost in a large-scale composite mirror due to the disadvantage that the thickness of the adhesion layer and the chemical composition are uneven, the yield is low in mass production, and the necessity of extensive maintenance is required. There were a lot of disadvantages.
