摘要
道路及隧道照明设施的规模越来越大,照明耗能在迅速上升。针对此问题,讨论了可行的照明节能新途径。设计出了一种时控节能照明电路。它依据气体放电光源在工作电流适当减少时仍能正常运行的原理。在后半夜车稀人少时,自动降低光源电流,减少在路灯系统能耗中占主要比例的光源能耗,以达到路灯系统整体节能的目的,而且还避免了光源后半夜的过压运行,延长了路灯寿命。与传统照明电路相比,节电率在20%以上。该电路实施方便,运行可靠,可使照明工程既满足功能性的要求,又能实现最大限度的节能。
With the illumination facility scale of road and the tunnel enlarging, the consumed energy of illumination is rising rapidly.In an effort to solve the problem,we have discussed a new feasible way of conserving energy for illumination. A kind of light circuit of real-time control was designed.It bases on the principle that gas-discharge light source functions even under lower operating current.In the late night, electric current of the light source drops automatically; as a result, the energy, consumption in the lighting system decreases,and the aim of saving energy was achieved.In addition,it also prevented the light source from working at higher electric current late at night,and prolonged the life of light tubes. Compared to the traditional lighting circuit,the rate of power saving is over 20%.The circuit runs easily and stably.The lighting projects, with full functions, eliminate energy consumption to the max extend.
