The hands touch the surface of the lamp body to generate induction signals to realize the on-off and the light adjustment of the desk lamp. The utility model has the functions of brightness memory and self lock for power failure, and has the advantages of novel structure, convenient operation, rich variation of brightness control, high sensitivity, strong interference resistant performance, reliable work, and long service life. The utility model can be extensively used in households, offices and hotels.
Description
The utility model relates to lighting device, and a kind of touch opens and closes lamp dimmer.
Existing various desk lamp all is made of ac power switch, lamp body, lamp holder and bulb basically, and structure is original, and style is outmoded; Though some lamp dimmers that appear on the market in the recent period are provided with dimmer, also be to realize opening and closing and light modulation by the operation potentiometer knob, night, dark operation was very not convenient, and frequent operation is with the passing of time, easily produced electric fault because of device mechanical wear; When stopcock is forgotten in power failure, easily take place also that the incoming call back light is kept burning day and night to cause waste.
The purpose of this utility model is to improve the keying dimming mechanism of existing desk lamp, makes it to realize without mechanically actuated operation to open and close and stepless dimming, and possesses the power failure auto-lock function; Easy to use, simple in structure, reliable operation, the life-span is long.
The purpose of this utility model is to reach by the design that following touch opens and closes lamp dimmer.It is made of lamp body, lamp holder, bulb and touch keying light adjusting circuit, it is characterized in that adopting vacuum coating technology to carry out the conductive film that has covered one deck light on insulation lamp body surface, and conductive film passes through high value resistor R
4Be coupled to and open and close on the integrated package that produces keying, light modulation instruction in the light adjusting circuit; The master of this integrated package detects electrode by thresholding diode D
1, input electrode is by filter R synchronously
2C
3Be coupled on the bidirectional triode thyristor BCR, its gradually the dark signal input utmost point be connected to and gradually put out on the gradually bright control circuit, this circuit is by normally closed push button switch and capacitor C
5Compose in parallel; Main detecting a sensitivity adjustment resistance R is arranged between electrode and the mains supply
3, its Standard resistance range is at 400-800K Ω, and its optimum value is chosen in 560-750K Ω scope; In the mains electricity input end, designed a LC filter L=40 μ H, C=0.15 μ f is to absorb radio frequency interference.The DC power supply of integrated package and bidirectional triode thyristor is common half-wave rectifier voltage circuit.

Below in conjunction with accompanying drawing the utility model operation principle and characteristics are described further.
When arbitrary position, staff Touching controlling lamp surface, the human-induced signal is through resistance R
4Input integrated package Ic master detects electrode 5, if the touch time is 39～399 milliseconds, then circuit is in turning state, and promptly logical the change broken, and be disconnected flexible; If the touch time is greater than 399 milliseconds, circuit then is in the stepless dimming state, light from the brightest to secretly again from the darkest to bright, back and forth change continuously,, finger is left lamp body to required brightness, because circuit has brightness memory function (the brightness holder of Ic), will keep this brightness constant.When need turn-off, the very fast lamp body that touches, lamp promptly extinguishes.If touch fast again, then brightness is still as the past.
If will carry out the gradually secretly gradually bright control of light, can press AN, normally-closed contact is disconnected, then gradually put out signal by C
5The input Ic, make light by the locking brightness gradually deepening to extinguishing.Normally closed as if AN is reset to, touch lamp body with hand again, the time, then gradually to bright variation, being transferred to needed the brightness hand from lamp body from the darkest in brightness greater than 399 milliseconds, the brightness locking.
After electrical network had a power failure for some reason, circuit just was broken into self-locking state, and behind service restoration, if the unmanned lamp body that touches, because of non-inductive signal input Ic, circuit will keep off-state.
Cause misoperation, R for preventing that lamp body surface large tracts of land conducting film from producing to disturb to circuit
3Resistance must in 400～800K Ω scope, choose the R that this is routine
3Optimum value is elected 560K Ω as.Diode D
1In order to the skew of restriction BCR gate voltage, guarantee reliable operation and stable.
The utility model has the advantages that novel structure, to open and close light modulation easy to operate, that brilliance control changes is abundant, highly sensitive, antijamming capability by force, reliable operation, long service life, and have brightness memory and power failure auto-lock function.
