美国Plumly航空装备公司最近设计出一种新型光源装置,采用这种装置后,即使飞机失事,机舱内烟雾密度超过90％时,乘客也能够看见光耀夺目的安全灯所指示的出口处,从而能够迅速逃离机舱,这种光源装置完全符合美国联邦航空局所制定的“一切民航飞机机舱的出口太平门必须有显著的安全标记”的新规则。 这种先进的光源装置是由一套安装在驾驶舱内的逻辑电路控制的电源和座舱内一连串照明灯具所组成,由两组铅酸蓄电池供电,电流通过一种由热塑绝缘合成橡胶(TPE)制成的扁平电缆。这种新型电缆具有耐燃性,而且不会释放出有害 Plumly Aerospace recently designed a new light source unit that enables passengers to see the exit indicated by a dazzling safety light even when the plane crashed and the smoke density in the cabin exceeded 90% Quickly fled the cabin, this light source device in full compliance with the FAA has developed “all civil aircraft cabin exit fire exit must have a significant safety mark” new rules. The advanced light source consists of a set of power supplies controlled by a logic circuit installed in the cockpit and a series of lighting fixtures in the cockpit powered by two sets of lead-acid batteries passing through a battery of thermoplastic insulation elastomer (TPE ) Made of flat cable. This new cable is flame resistant and does not release harmful effects
