Description
Technical field
The utility model relates to AC LED lighting technical field, espespecially a kind of singly-bound soft-touch control AC LED lamp.
Background technology
Led light source as green, energy-conservation, power saving, long-life the 4th generation lighting and be a dark horse, extensively concerned, develop rapidly in high gear.Present led light source is that (semiconductor device of 2～3.6V) work must provide the suitable direct current could be normally luminous to low-voltage.The technology of direct current (DC) driving LED light source luminescent is more and more ripe, because the power supply that our normal lighting uses is that (AC 100～220V) for high-voltage alternating, so must obtain with the technology of step-down lower voltage, commonly used is transformer or Switching Power Supply step-down, then will exchange (AC) and be transformed into direct current (DC), be transformed into again dc constant current power supply, just can impel led light source luminous, so when it is applied to general AC power-supply system (during such as AC 220V, just must see through and add transformer and smoothly operation of rectification circuit, the life-span bottleneck of LED power supply is just becoming a basic source of a lot of problems, at present a lot of LED light fixtures break down, be not that the led light source life-span is most, but AC-DC conversion and rectification circuit that the LED light fixture uses broken down first, and be therefore limited on range of application and popularization degree.
Summary of the invention
A kind of singly-bound soft-touch control of the utility model AC LED lamp is characterized in that for above-mentioned deficiency, a kind of working stability is provided, does not use AC-DC conversion and transformer, the singly-bound soft-touch control AC LED lamp of the direct driving LED light source luminescent of AC power.
To achieve these goals; technical solution of the present utility model is: a kind of singly-bound soft-touch control AC LED lamp is comprised of lamp holder, contact switch control circuit, current-limiting protection circuit, AC led array and lamp housing; lamp holder is connected with external ac power source; and be connected in series cartridge fuse with the centre that is connected of live wire; connect piezo-resistance between live wire and the zero line; current-limiting protection circuit is connected with the AC led array, and contact switch control circuit is connected with current-limiting protection circuit with lamp holder.
Described contact switch control circuit is made of resistance R 1, R2 and R6～R8, capacitor C 1～C5, diode D1～D4, voltage stabilizing didoe D5, integrated IC, touch sheet M and bidirectional triode thyristor TRIAC.
Described current-limiting protection circuit is made of thermistor RT and resistance R 3～R5.
Further, described bidirectional triode thyristor also can substitute with relay.
The beneficial effects of the utility model are: finger is had a touch with touch sheet, the alternating current that human body leaks, its positive half cycle signal enters the input pin of IC, make the counter-rotating of IC monostable circuit enter instantaneous, its output pin is high potential by original electronegative potential saltus step, this high potential through resistance to capacitor charging, the current potential of reseting pin is risen, when rising to reset potential, the IC monostable circuit resets, so touch sheet of every touch is just exported the positive pulse wave of a fixed width, and make the counter-rotating of IC bistable circuit once, its output pin current potential just changes once, when output pin current potential was high potential, the control utmost point that triggers bidirectional triode thyristor TRIAC made its conducting, and then conducting AC led array makes it luminous, thus, every touch one-time electrode sheet M just can realize the action of " opening " or " pass ", reaches the effect that the AC led array is lighted or extinguished.
