Abstract
The utility model relates to a light sensitive controller for middle or large road lamps, which can automatically control lines for road lamps with large power to close in daytime and open in night according to the dark DEG of ambient light. The light sensitive controller for middle or large road lamps is composed of a light sensitive prove, a regulating device, a (NE555) time-base circuit, a relay drive circuit, an alternating current contactor and a power section. The light sensitive controller for middle or large road lamps can automatically control lines for road lamps with large power to close in daytime and open in night according to the dark DEG of ambient light to reach the purpose of saving electricity.
Description
The utility model relates to the photosensitive automatic controller of a kind of electricity saving of road lamp, it can control automatically night and daytime street lamp the self-con-tained unit of turning on light and turning off the light, especially can control the photosensitive automatic controller of medium-and-large-sized power electricity saving of road lamp of large power road lamp circuit.
At present, the automatic light-operated switch of listing, power is little then tens watts, one kilowatt of hundreds of only greatly then, as for mechanical medium-and-large-sized power electricity saving of road lamp controller all is to adopt electric power timing controlled of quartzy hour of SDK-2 type (dispatch from the factory fix on 24:00 change day), though adjustable, but still can not reach and save purpose of power saving most, and sensitivity, stability and reliability are all very undesirable.
The purpose of this utility model provides the photosensitive automatic controller of a kind of medium-and-large-sized power electricity saving of road lamp, it can not only be according to ambient light bright-dark degree, automatically control night and daytime street lamp turn on light and turn off the light, and can reliablely and stablely control powerful public lighting circuit automatically.
The purpose of this utility model be achieved in that at dusk when the colour of sky enter gradually low light level low-light zone 3/5 the time, IC (NE555) time-base circuit (2), (6) terminal potential rise, when rising to 2/3Vcc, (3) end output becomes low level, relay K P contact adhesive this moment, A.C. contactor energising work, street lamp is lighted, relay indicating light VD
2Bright; Early morning when the colour of sky by enter gradually night low light level low-light zone 2/5 the time, IC (NE555) time-base circuit (2), (6) terminal potential descend, when reducing to 1/3Vcc, (3) end output is by the low high level that becomes, device KP contact was opened when continued this moment, the A.C. contactor outage, and street lamp extinguishes.Power supply indicator VD
5Be used for detecting civil power, only otherwise have a power failure light yellow always.
Owing to adopt such scheme, just can realize controlling automatically the large power road lamp circuit in the turning on light automatically and turning off the light of night and daytime, the circuit theory novelty, simple in structure.

3A burning voltage is provided after the filtering,, thereby has guaranteed that the long-term continous-stable of this device moves work reliably so the electricity-saving controller that provides power supply than other power transformer step-down is durable in use reliable and stable.
The utility model is the photosensitive automatic controller of a kind of medium-and-large-sized power electricity saving of road lamp, it has can be according to ambient light bright-dark degree, automatically the turning on light and turn off the light of control street lamp, power saving rate is high and the high-power advantage of control public lighting circuit, the street lamp power controlling of this device is between 5KW-300KW; Electric energy is saved electric 10%-15% than SDK-2 type electric power timing controller.In a word, this device has the power saving rate height, and control public lighting circuit power is big, and long-term stable and reliable operation continuously especially is fit to the automatic control of the public lighting circuit of China big and medium-sized cities and small town, county town.
