摘要
对防爆LED灯具光辐射的点燃机理、保护方式以及合格判定要求进行了论述,分析了防爆LED灯具的光源保护型式以及各种光源保护型式的光辐射特点,再从优化LED驱动电路设计和应用固有安全特性LED的角度对防爆LED灯具的光辐射设计要点进行了深入探讨。
It introduces the ignition mechanism, protection method and acceptable criteria of optical irradiance, analyses the protection type of explosion - proof LED luminaire and their optical irradiance features, then gives a detailed thought of optical irradiance design features in explosion -proof LED luminaire based on optimization design of LED driven circuit and application of inherently safety characters.
