摘要
飞机航行灯是1种低电压卤钨光源,设计使用寿命2 000h。卤钨灯在生产过程中,需要对石英管进行放气分析、断面检测和压力实验,以便挑选合格产品。绕制灯丝需要剔除有缺陷的钨丝,稳定的钨丝结晶使灯丝具有天然的抗震性。Kr气和循环剂混合后,通过低温冷冻技术2次分离,实现高压强填充。使用国产原材料可以生产出符合国际标准的产品。
Aircraft navigation light is a kind of low voltage halogen light source, the design service life is 2,000 hours. In the lamp production process, the gas analysis of quartz tube, profile measurement and pressure test could help choose qualified products. Before winding filament, the defective tungsten filaments need to be eliminated for stable crystalline generates the aseismic nature of filaments. Mixing Kr gas and the recycling agent and utilizing the separate cryogenic technology, realize high pressure fill. International standard products can be produced with domestic raw materials.
