Lighting systems are deployed in aircraft to illuminate the interior and exterior of aircraft, thereby offering enhanced visibility of the surrounding. Lighting comprises signaling devices as well as other display devices, which increase the conspicuity of the aircraft. The aircraft lighting market has witnessed significant growth over years, owing to increase in trend of advanced lightings to be installed in aircraft. For the purpose of analysis, the global aircraft lighting market is segmented into interior light, exterior light, aircraft application, light type, and region. The report provides details of various interior lights such as emergency lights, specialty lights, wash lights, reading lights, and lavatory lights. In addition, it overs covers information of exterior lights, including aircraft visibility lights, pilot lights, and specific purpose lights. The study further highlights the revenue generated from various aircraft type, which include commercial, business jets, military, and helicopters. Moreover, it focuses on various light type, including florescent light and LEDs. Furthermore, the report includes the revenue generated from aircraft lightning systems across various geographical regions such as North America, Europe, Asia-Pacific, and LAMEA.

投资 建议 ：我们认为， 航空 发动机具有极其重要的战略地位， 国产化势在必行，当前军用航空发动机投资主要围绕两条线。

北斗产业自主可控、良性发展的内循环生态基本形成。北斗三号系统已正式建成，具备了对全球提供服务的能力。北斗产业链可分为：上游、中游和下游。上游基础产品是产业自主可控的关键，主要包括基础器件、基础软件、基础数据等。目前北斗系统国产芯片、模块等关键技术取得全面突破，性能指标与国际同类产品相当，并已形成一定价格优势。

Honeycomb sandwich is a structure with three layers, which offers high strength, stiffness, corrosive resistance, minimum raw material requirement. Increase in space and aviation activities across the world drives the market growth. These materials are widely used in the construction, automotive, and marine industries, as these provide remarkable mechanical properties and are lightweight, thus conserving fuel and reducing the weight of the marine vehicle. However, capital-intensive nature due to high cost of production and raw materials hampers the growth of the honeycomb sandwich material market. Meanwhile, 3D printing of honeycomb panels is expected to provide lucrative opportunities to the honeycomb material manufacturers.

碳纤维系列报告分为三篇，此为最后一篇，主要梳理全球碳纤维生产龙头发展历程及优势、以及我国企业发展模式及依托，并以此为借鉴，探讨中国碳纤维生产企业的突破重点及我国碳纤维特色发展之路。

试验检测全程伴随装备发展：试验、检测是保证现代装备实现先进性能指标的重要环节，贯穿装备的全生命周期。军工装备从最初的立项论证和方案设计，到最后的性能试验、交付和鉴定等各个环节，都离不开相应的试验、检测项目作为验证和支撑。

7 月初以来，在中航沈飞、洪都航空等新型军机主机厂涨幅带动下，军工板块形成系统性行情。本轮行情的主导因素有二：一是基本面变化：新型军机、航天装备需求的结构性加速，叠加过去五年一批优质军工资产通过IPO 或重组进入A 股，核心股票池腾笼换鸟，十数个军工标的未来五年可以预期30%以上复合业绩增速；二是板块轮动：自2015 年上一轮牛市见顶以来的过去5年，军工板块总体走势处于单边下行通，主流军工标的2020PE 回落至25~45倍之间，与前期持续强势的其它科技、医药、消费板块横向比较优势突出；机构持仓显著低配，主动公募基金军工持仓比例自2016Q2 的5.6%（标配3.0%）下降至2020Q2 的0.9（标配2.3%）
