Description
Technical field
The utility model relates to the LED field of illumination lamp technology, espespecially a kind of infrared remote control AC LED lamp.
Background technology
Compare with incandescent lamp, Halogen lamp LED, fluorescence fluorescent lamp, energy-saving fluorescent lamp, the LED light fixture have more energy saving, more long-lived, more the high performance-price ratio of efficiency arranged, the rising star in illuminating lamp source, 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.Because the power supply that our normal lighting uses is 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 (such as AC 220V), just must see through and add transformer and smoothly operation of rectification circuit, increase exceptional space and cost, and because voltage transitions, the factors such as rectification circuit energy consumption and high current practice cause more electric energy loss.
Summary of the invention
A kind of infrared remote control AC of the utility model LED lamp, it is characterized in that for above-mentioned deficiency, a kind of working stability is provided, does not use AC-DC conversion and transformer, take full advantage of the remote controllers such as domestic TV, air-conditioning as remote control transmitter, the infrared remote 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 infrared remote control AC LED lamp is comprised of lamp holder, infrared reception control circuit, current-limiting protection circuit, AC led array, lamp housing and infrared transmitter; 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 infrared reception control circuit is connected with current-limiting protection circuit with lamp holder.
Described infrared reception control circuit is made of resistance R 1, R2 and R6, capacitor C 1 and C2, electrochemical capacitor C3 and C4, diode D1～D4, voltage stabilizing didoe D5, integrated IC, infrared receiving terminal IRM and bidirectional triode thyristor TRIAC.
Described current-limiting protection circuit is made of thermistor RT and resistance R 3～R5.
Described infrared transmitter is family's TV, air-conditioning or refrigerator remote control infrared transmitter commonly used.
Further, described bidirectional triode thyristor also can substitute with relay.
The beneficial effects of the utility model are: the infrared signal that infrared transmitter sends, after infrared receiving terminal receives, be input to the bistable circuit trigger end of integrated IC, and make integrated IC bistable circuit counter-rotating once, its output pin current potential also just changes once, when output pin current potential is high potential, the control utmost point that triggers bidirectional triode thyristor TRIAC makes its conducting, and then conducting AC led array makes it luminous, thus, signal of the every reception of infrared receiving terminal, just can realize once the action of " opening " or " pass ", reach AC power and directly drive the AC led array and make it the effect lighting or extinguish, simple and convenient during use, safety and stability, the life-span is long.
