Description
Technical field
The utility model relates to road night illumination electricity-saving appliance, particularly relates to a kind of electronic power saver for street lamp.
Background technology
All gas discharge type lightings such as the high-pressure sodium lamp of using, low-pressure sodium lamp, metal halide lamp, high-pressure mercury lamp, fluorescent lamp are widely used in public illumination environment such as town road, highway, bridge, tunnel, gardens, harbour, sightseeing scape lamp, physical culture square, recreation ground, advertising lamp box at present.These gas discharge type lightings need high voltage and heavy current when starting, after starting steadily, only need low voltage and electric current, can not influence its illuminance, suitably control voltage parameter and reach purpose of saving.Contemporary cities road lamp system in large scale is also considerable to the consumption of electric energy, and particularly street lamp generally needs all night kept burning day and nightly, and the energy saving effect of street lamp can not be underestimated.Except selecting energy-conserving product at the lighting device and keeping realizing that by Based Intelligent Control energy-conservation also is very effective and necessary the reasonable illuminance.Current control voltage (step-down) generally is to come pressure regulation by series reactor or employing electromagnetic voltage adjusting device, but no matter is the own loss of series reactor and electromagnetic voltage adjusting device, and the power saving rate problem that reduces battery saving arrangement all can be arranged.
The utility model content
The technical problems to be solved in the utility model is, provide a kind of by using power electronic device, the programmable, intelligent controller, low-voltage electrical apparatuses etc. carry out system's automatic voltage regulation operation and function is controlled in pressure regulation automatically, make illuminator reduce too high voltage at night, rationally pressure regulation, switch on time, make road lamp system reach energy-conservation purpose and prolong useful life of lighting, to reach the energy-conservation purpose electronic power saver for street lamp of road lamp system.
The technical scheme that adopts is:
A kind of electronic power saver for street lamp is intelligent lighting control equipment, is installed on the circuit front end, is made up of CPU, current sensor, voltage sensor, drive circuit, voltage-regulating system and the manual controller of DC power supply.Described current sensor is connected intelligent controller or Programmable Logic Controller with voltage sensor by the A/D conversion, intelligent controller or Programmable Logic Controller connect the input of CPU, the output of CPU connects drive circuit by the D/A conversion, drive circuit connects voltage-regulating system, voltage-regulating system link road lamp apparatus.
Above-mentioned manual controller's link road lamp apparatus.
Above-mentioned CPU input is connected with the time relay and photo controller respectively.
Above-mentioned CPU output is also with fault or overload or overtemperature detects and bypass circuit is connected.
Above-mentioned CPU connects intelligent communication system by the RS-485 interface.
Above-mentioned street lamp device adopts the automatic idle dispersion compensation of single lamp electric capacity.
Intelligent lighting control equipment of the present utility model brings the energy-saving effect of 25-40% by the control to electrical network overvoltage/undervoltage and energy conservation for the user.Simultaneously, can make its life-span prolong 3-4 doubly to the protective effect of using electricity system, save light fixture maintenance, renewal cost greatly.The direct benefit that the electricity charge are saved combines with the indirect benefit of protection light source, can make user's cost of easily recouping capital outlay in a short time, and continue create beneficial result.
