Description
Technical field
The utility model relates to field of light fittings, specifically a kind of automatic control type LED lamp.
Background technology
At present, the sense light of known energy automatic control switch has following several:
1, sound control type, this lamp is to come control switch according to the induction to sound, but this acoustic control lamp needs the sound more than 10 decibels could control the switch of lamp, can make noise like this, influence other people rest, and when nobody, have automobile sound or other noisy sound that lamp is lighted automatically, and form misoperation, cause energy waste;
2, heat is released infrared type, this lamp is bright with infrared thermal release electric body induction circuit control lamp, though this kind lamp behaviour is very stable, but the angle of its control has only about 30 degree, promptly having only lamp the place ahead to have the people to walk out-of-date lamp could be bright, if the people from behind, about walk out-of-date lamp can be not bright, so induction range limits to very much, the position of installation and direction are all difficult to be determined;
3, time controlled type, this lamp adopt the switch of timer control light fixture, no matter nobody are arranged, and needing all can timing switch, so caused a large amount of wastes of the energy, electric energy is low, does not reach energy conservation and environment protection;
4, induction control type, this kind lamp is to utilize the principle design of human body direct-to-ground capacitance control lamp control plate concussion failure of oscillation to produce, the tablet of this lamp is 20cm * 20cm when big, and the control maximum distance is about 2m, so use inapplicable corridor of the lamp of this type and office space.
5, touch type control type, this control mode utilize the human body above earth potential to control, because this lamp mostly directly uses behind capacitance decompression with 220v voltage, so both dangerous, also unhygienic.
The utility model content
Be to solve the problem that prior art exists, the utility model provides a kind of and does not need sound, is regardless of angle, the people is to being bright Doppler effect control type LED lamp.
The utility model is achieved in that
A kind of Doppler effect control type LED lamp, comprise lamp holder, housing, electronic circuit board, electronic circuit board shell, luminosity scale, described electronic circuit board is arranged in the electronic circuit board shell, electronic circuit board one end is connected with lamp holder, the other end luminosity scale interior with being arranged on housing is connected, described luminosity scale is provided with several LED, and described lamp holder is provided with can launch the electromagnetic antenna of high frequency phase modulation.
As a kind of preferred version of the present utility model, described antenna can be linear, and length is 2～10cm.
Described electronic circuit comprises: phase modulation demodulator circuit, amplification and rectification circuit, monostable circuit, light-operated circuit, delay circuit, phase modulation demodulator circuit, amplification and rectification circuit, monostable circuit connect successively, and light-operated circuit is connected amplification and rectification circuit and monostable circuit A
3Between, wherein, be provided with the triode V that can produce the high frequency phase signals in the phase modulation demodulator circuit
1With coupling capacitance C
2, a pin of triode is connected with inductance L, inductance L and coupling capacitance C
2Connect.
Operation principle of the present utility model is: launch high frequency phase modulation electromagnetic wave in the zone of 360 degree towards periphery by antenna, when running into the human body of motion, antenna is given in reflection of electromagnetic wave, the electromagnetic wave of reflected back produces difference frequency phase-modulated signal by triode with the electromagnetic wave of launching in circuit, this difference frequency signal is coupled through coupling capacitance, demodulation then utilizes this difference frequency phase-modulated signal to control the light on and off of light fixture.
The utlity model has following advantage:
Solve the deficiency that the sound control type lamp needs sound to control, solved the interfering noise problem that the sound control type lamp " has illuminated oneself, influenced other people ";
Solved heat and released the defective that infrared type etc. is subjected to angle limits, simultaneously also specific heat to release infrared type lamp cost low;
Solved the energy waste problem of time controlled type lamp, the electric energy height reaches ideal control effect;
Can distinguish people and animal, because the electromagnetic wave of reflected back produces the difference frequency phase-modulated signal by triode with the electromagnetic wave of launching again in circuit, the difference frequency phase-modulated signal is through coupling demodulation, amplification, shaping, so can distinguish people or animal via mistake, then lamp can be not bright if animal via is crossed;
Do not need sound, be regardless of angle, the people extinguishes behind the time-delay certain hour automatically to promptly bright.
