electropank Posted August 30, 2004 Report Share Posted August 30, 2004 Can any body tell me how can I make a power-full Infrared flud light. If yes please give me full discription along with part list ( Part Specifications ) & ciruit diagram too. Quote Link to comment Share on other sites More sharing options...
audioguru Posted August 31, 2004 Report Share Posted August 31, 2004 Hi Electropank,Welcome to our forum.Anything that is hot radiates infrared energy. The sun, a fire, an electrical heater and even living mammals give off infrared energy.What are you making that requires you to flood an area with infrared "light"?

ante Posted September 1, 2004 Report Share Posted September 1, 2004 Electropank,Is it for your video camera or your Winchester? Quote Link to comment Share on other sites More sharing options...
steven Posted November 6, 2004 Report Share Posted November 6, 2004 :) infrared spotlights are usefull for close circuit tv cameras so you can see in the dark like night vision jayvar electronics in australia sells the kits for these infrared spotlights , Quote Link to comment Share on other sites More sharing options...
Guest Yevgenip Posted November 21, 2004 Report Share Posted November 21, 2004 Use an Infrared lamp and connect it to a 555 timer. it will blink fast enough to create infrared.Used it once to make a parking helper.Yevgeni. Quote Link to comment Share on other sites More sharing options...

Guest Yevgenip Posted November 22, 2004 Report Share Posted November 22, 2004 Good Idea!I'll post it in a while (Want to make it look good). ;D Quote Link to comment Share on other sites More sharing options...
Guest Yevgenip Posted November 24, 2004 Report Share Posted November 24, 2004 Well, Here it is: My infrared parking helper circuit.Parking_Helper.zip Quote Link to comment Share on other sites More sharing options...
audioguru Posted November 24, 2004 Report Share Posted November 24, 2004 Hi Yevgeni,Questions about your nice parking helper circuit:1) Doesn't the sensitivity of the circuit depend on the reflectiveness (colour and shinyness) of the wall? Perhaps it should have a sensitivity adjustment.2) Wouldn't the circuit be more stable by using a lower-voltage regulator? If the car battery's voltage drops much below about 15V, a 12V regulator may drop-out. Perhaps a 9V regulator is more suitable.3) Using a value of only 33 ohms for the IR transmitter's current limiting resistor, isn't the resulting >300mA of current rather high for the IR transmitter and the 555? However, I do notice the 1:10 duty cycle that reduces the average current.4) You seem to be using the IR receiver as a photo-voltage source. Wouldn't it be more sensitive if it was used as a reverse-biased photo-conductor (leaks current with IR pickup) or by using an IR photo-transistor and the opamp used as a capacitor-input non-inverting amp?5) Doesn't C3 charge after a few cycles then without having a diode to discharge it for each cycle, reduce the output voltage of the rectifier?
