Description
Technical field
The present invention relates to a kind of LED delay-action control system, particularly relate to one and can provide light within the regular hour, and realize when disconnecting main electricity completely, can effectively lower because electrical appliance is energized the LED delay-action control system of brought potential faults for a long time.
Background technology
The lamp decoration of existing delay-action controls product in the market, and uses for many years, and its control mode all realizes when not disconnecting main power source, even if after light fixture extinguishes, its controller still needs electric current maintenance work in a small amount, can not accomplish to disconnect main electricity completely.
Wait for me delay-action function, can realize the function of delay-action when main electricity disconnects completely.Its principle is in great power LED work simultaneously, charges, complete charging in about five seconds to the super capacitor being built in driving power.After main electricity disconnects, wherein one group of LED light source is powered.Delay time can control at 5 seconds ~ 15 seconds, makes keep certain light source in space, avoids because light suddenly disappears to the mobile inconvenience produced of people.
The energising of the light fixture of current indoor and power-off are all realized by fixing switch on the wall, consider owing to waiting many factors on design and installation, often this switch fails to be installed in the most rational position, therefore appear in the space that still need disappear at light after closing light fixture to move, due to insufficient light, in moving process, there will be potential safety hazard, cause injured.
Summary of the invention
The present invention is in order to overcome the defect of prior art, object is to provide one can provide light within the regular hour, and realize when disconnecting main electricity completely, can effectively lower because electrical appliance is energized the LED delay-action control system of brought potential faults for a long time.
The technical solution adopted for the present invention to solve the technical problems is: a kind of LED delay-action control system, comprise control section and the Lights section, the Lights section includes two light source groups, and described control section comprises LED driver, diode, capacitor, control chip, sampler and inductor.
Further, the output of described LED driver is provided with the C output line and D output line that form loop, C and D output line is connected the first light source group and sampler; The output of LED driver is also provided with A output line, and sampler is located between A output line and C output line.
Further, the output of described LED driver is also provided with B output line, and B output line and C output line are in series with secondary light source group, and diode and control chip are located on B output line, B output line is also provided with inductor and capacitor is formed in parallel with C output line, control chip ground connection.
Further, described LED driver is LED constant-current driver.
Further, the light source of two described light source groups is the LED of 1W or 3W.
Further, described first light source group is 6 LED, and secondary light source group is 1 LED.
Further, A output line, B output line, C output line, be respectively equipped with A binding post, B binding post, C binding post, D binding post between D output line and corresponding light source group.
The operation principle of LED delay-action control system of the present invention is: when connection LED driver input, during civil power 220V, LED driver is powered to two groups of light source groups respectively, first light source group: exported by D output line, the first light source group is connected to by D binding post, be connected to sampler by A binding post, then be connected to C output line by sampler and form loop, the first light source group normally lights.Secondary light source group: exported by B output line, charged by diode pair capacitor, when condenser voltage meets the work required voltage of control chip, control chip is started working, and utilizes inductor to form closed booster circuit, dummy output terminal output voltage, secondary light source group is connected to by B binding post, be connected to the earth terminal of control chip again by C binding post, the other end of capacitor is connected to C output line and forms loop, and secondary light source group normally lights.
When civil power 220V disappears, LED driver loses normal operating voltage, and LED driver does not work, and the first light source group no-output, the first light source group does not work.And when two light source groups normally work, capacitor is charged due to the charging circuit be made up of diode and capacitor, after civil power 220V disconnects, capacitor still has enough electric charges by secondary light source group work 5 ~ 15 seconds (time of this delay establish concrete condition and determine).
In sum, LED delay-action control system of the present invention can provide light within the regular hour, and can realize when disconnecting main electricity completely, can effectively lower because electrical appliance is energized brought potential faults for a long time.Had basic light, both can lower because light suddenly disappears produced discomfort, can facilitate movement again, this function is without the need to long-term energising simultaneously, substantially prolongs the life-span of light fixture and lowers failure rate.
