Control of tungsten lamp with infrared pulse
the infrared receiver connected to the relay then access tungsten lamp. can be Tungsten combustion achieved with ir pulse?
The MCU is send out the pulse to ir led strip, now generally used the integrated receiver,it has been the pulse signal amplification, detection, filtering out the original encoded signal to restore the original encoder pulse signal frequency,in generally the original code is very low frequency pulse signal from MCU, need to use the 38K pulse modulation when When transmission of pulse, the modulated waveform is the result of multiplying the two pulses，
can also be done with the 38K pulse train input signal by a non-goalkeeper coding,the tungsten lamp is no ordinary direct drive, the reaction speed is not up to the requirements (due to high frequency signal receiving head, the relay operation a lot of inertia,the Relay not to do that Continuous and Quick work。but has been energized until there is no signal.The idea is a good one in theory ,but the condition that the average voltage of the signal can reach the relay minimum operating voltage.) I used to drive the laser tube with ir pulses, the effect is very good.
