Description
Technical field
The utility model relates to the LED lighting technical field, especially relates to a kind of LED corridor lamp control device.
Background technology
We can not mate at soft-touch control, audio-switch, the switch of infrared induction and the common LED corridor lamp of employing at present; These switches have resistive touch switch and capacitor type touch switch by the on-off principle classification, are divided into single live wire soft-touch control and double wire system soft-touch control (live wire and zero line) by the mode of connection.Existing overwhelming majority of countries all is to adopt single live wire system wiring rule, and therefore, single live wire soft-touch control is the existing market main product.The double wire system soft-touch control is because of needing rewiring when mounted, even through walls holing, and application market seldom will progressively be eliminated by market.Promptly when we use common LED corridor lamp and above-mentioned switch coupling, the LED lamp can occur can't be light by induction; The phenomenon that stroboscopic perhaps when the LED corridor lamp is light, can occur; LED can exist and can't turn-off led light source when turning off the light at last, and the phenomenon of the light of promptly can having a surplus appears at above the LED corridor lamp.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of safe, efficient, reliable LED corridor lamp control device is provided.
For realizing above-mentioned purpose; The technical solution of the utility model is: a kind of LED corridor lamp control device; Be input to rectifier bridge D1 by city's electrical input signal through divider resistance R1 and filter capacitor C1; Output parallel connection electrochemical capacitor C2 and the DC voltage-stabilizing pipe D2 of said rectifier bridge D1, the output of said DC voltage-stabilizing pipe D2 is connected to controllable silicon Q1, and the output of said controllable silicon Q1 supplies load LED lamp to use through the constant current signal of resistance R 5 control outputs.
The output of said DC voltage-stabilizing pipe D2 also connects a current-limiting resistor voltage divider R3.
The said controllable silicon Q1 resistance R 2 of connecting.
Through adopting above-mentioned technical scheme; The beneficial effect of the utility model is: the utility model has adopted silicon controlled control in the circuit that adopts the capacitance-resistance pressure drop; Controllable silicon has the effect of control forceful electric power, between silicon controlled anode and negative electrode, imports forward voltage, also imports forward voltage at the control utmost point simultaneously; Controllable silicon satisfies the output signal that is triggered after the condition of conducting makes the LED corridor lamp realize normally lighting, close, not have stroboscopic, normal mode of operation such as do not turn off the light.
Description of drawings
Fig. 1 is the circuit theory diagrams of a kind of LED corridor lamp of the utility model control device.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, a kind of LED corridor lamp control device of the utility model is normally imported by the civil power of AC220V/50Hz; After the filtering of its input signal through resistance R 1 dividing potential drop and filter capacitor C1; Be input to rectifier bridge D1, rectifier bridge D1 becomes the DC direct current with the AC AC rectification of the civil power output of AC220V/50Hz, the output parallel connection electrochemical capacitor C2 filtering of rectifier bridge D1; And provide 5.1V voltage to output to controllable silicon Q1 through DC voltage-stabilizing pipe D2; Controllable silicon Q1 control input is broken off with output fully, and 3 resistance dividing potential drops of resistance R metering function that the output of DC voltage-stabilizing pipe D2 connects is after the resistance R 2 of controllable silicon Q1 series connection is adjusted output current limiting with signal; Constant current signal through resistance R 5 control outputs supplies load LED lamp to use, and forms required LED corridor lamp control device.
More than show and described basic principle and the principal character and the advantage thereof of the utility model; The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the explanation that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection range to be defined by appending claims and equivalent method thereof.
