摘要
利用现有适用于1区的隔爆型防爆灯具,重新设计了内部防爆电池结构、逆变器和驱动电源的安装及散热方式,并对灯具进行了温度和配光实验,理论和实验证明,设计的LED灯具在正常供电时,输出光通量大于4000流明,当正常电源被切断时,应急电池供电仍然可以维持100%流明输出90分钟。
By making full use of existing Zonel flameproof enclosures ＂d＂ type LED lighting fixture, this article gives an example of re - designed structure of internal explosion proof battery, installation mode and heat - dissipation method of inverter and driver and associate temperature and light distribution test. Theoretical analysis and experiments demonstrate that, When this LED light- ing work under normal status, the output luminous flux is more than 40001m. when power supply is cut off, the emergency battery can still maintain 100% lumen output for 90 minutes.
