As shown in Figure 1, the intelligent road lamp electricity-saving control device, comprise the main circuit 1 that is connected with electrical network, the output of described main circuit 1 is parallel with voltage signal sampling circuit 2, current signal sampling circuit 4, street lamp start-up mode control circuit 6, microcomputer time-controlled switch control circuit microcomputer time-controlled switch control circuit 8 and direct current regulation circuit 10, the output of described voltage signal sampling circuit 2 is electrically connected with economize on electricity gear change-over circuit 3, the output of described current signal sampling circuit 4 is electrically connected with overcurrent and judges and change-over circuit 5, the output of described street lamp start-up mode control circuit 6 is electrically connected with time control and the automatic control conversion selects circuit time control and automatic control conversion to select circuit 7, the output of described microcomputer time-controlled switch control circuit microcomputer time-controlled switch control circuit 8 is electrically connected with function conversion driving circuit function conversion driving circuit 9, described function conversion driving circuit function conversion driving circuit 9 is electrically connected described main circuit 1, the output of described microcomputer time-controlled switch control circuit microcomputer time-controlled switch control circuit 8 also is electrically connected respectively described economize on electricity gear change-over circuit 3 and described time control and automatic control conversion and selects circuit time control and automatic control conversion to select circuit 7, and described economize on electricity gear change-over circuit 3 and described overcurrent are judged and change-over circuit 5 is electrically connected respectively described function conversion driving circuit 9, and the output of described direct current regulation circuit 10 is electrically connected respectively described economize on electricity gear change-over circuit 3, described overcurrent is judged and change-over circuit 5, described time control and automatic control conversion select circuit time control and automatic control conversion to select circuit 7 and described street lamp start-up mode control circuit 6.
The intelligent road lamp electricity-saving control device can and not need at the voltage (namely under the automatic control state) of setting to work under 100% regulation voltage (being under the time control state) two states that throws light on.Under according to time period time control state, the course of work curve of lighting load terminal voltage U and time t as shown in Figure 2.
Lighting load is in start-up course, if starting resistor too high or too low useful life that all can affect light fixture, existing phenomenon can appear puncturing in overtension easily, causes an ancient egg-shaped, holed wind instrument of illuminating lamp bad.If brownout can make again illuminating lamp repeatedly start the accelerated ageing that flicker causes lamp.For guaranteeing the optimum voltage value when street lamp just starts, this device is by street lamp start-up mode control circuit 6 control of delaying time, be added in voltage on the illuminating lamp during startup and be set as the I shelves economize on electricity voltage (voltage between phase line and the zero line: 210V~220V), through 5~10 minutes, the illuminating lamp soft start is complete enter stable operation after, send instruction by microcomputer time-controlled switch, according to the economize on electricity gear magnitude of voltage operation of setting.Such as 0~0.1 this time period among Fig. 2.From 0.1~1 this time period (as: evening 6: 30~10: 00) street lamp according to the stable operation of this section setting voltage value, power saving rate is about 15%, impact little (human eye is difficult to aware) on illumination, when the time arrives 1~2 this time period (as: 10: 00~12: 00 evening), street lamp can continue operation according to the economize on electricity gear magnitude of voltage of this section setting again, this moment, illumination can descend to some extent, power saving rate is about 25%, when the time arrives 2~3 these time periods (as: 12: 00~6: 00 morning), street lamp again can be according to the economize on electricity gear magnitude of voltage stable operation of this section setting, at this moment, illumination can further reduce again, but street lamp is extinguished, but can reach about 40% at the power saving rate of this time period.After the period 3 among time arrival Fig. 2 (after 6 of mornings), under the control of microcomputer time-controlled switch, street lamp all extinguishes.Period 3~4 is daytime, and street lamp does not work.This device repeats again the above-mentioned course of work after darkness.
