>> led in series or led in parallel ?? Since there won’t be a 280Ω Resistor, we will use the next big resistor i.e. I bought a corn cob led lamp it won't work on DC only AC, I think because of the capacitor that would block DC. pleas tell me i want now the difference between ntc and vairistor(mov)?2. Therefore, VS = 12V, VLED = 3.6V and ILED = 30mA. Kind regards. The circuit diagram for this circuit is shown below. Can I use 1w led's instead of 5mm straw-hat type?2. If yes then how many 1w led's I can use with this circuit? Ok means watt will be the same only volt increased, but by my thinking its equal to 40w brightness… am i right?????? Thank you very much friend…. Drone Kits Beginners Led Strip Light Kits Buy Online Hi, that's why I consider simulators useless….and I never use them. This observation is an indicator that the current within the circuit is decreasing. Here, you can see that the line connected to lamp 3 has a cut in the wire, so the bulb switch is off and the rest of the circuit is working properly i.e. Hi, you can use TVS diodes or NTC thermistor. This means that the voltage drop across the Resistor is 8.4V (12V – 3.6V = 8.4V). So, the Voltage Drop across the Series Resistor is, The current through the Resistor is same as the current through the LED as they are series. make sure each string has its own series a 22 ohm 1 watt resistor or any value between 15 and 30 ohms, Hello sir I want to run 300 leds of 5mm or 8mm to 230v AC main so wat will be the changes for the circuit, use 4nos of 75 LED string and connect them in parallel, no changes would be required in the existing design, How much nos of smd led will work for this circuit and if I want to connect 100 nos of smd leds what will be the changes for the circuit, Sir how much number of smd led will work for this circuit and if I want to connect 100 nos of smd led in series wat will be the changes for this circuit, Basit, since the maximum available voltage from the 220V input after rectification will be 330V so dividing this by the forward voltage of the LED gives 330/3.3 = 100. so yes 100 LEDs will be just OK and can be connected in series. When students wish to find out if the bulb will light up, they should check the following: Are both the metal casing and the tip of the bulb connected to the circuit? This does not include the light switches which should be wired in switch wire which contains 2 red cores. If yes, which capacitor can use for a 90mAh 230V op ? So all these benefits ultimately makes this 25 watt LED more efficient and cost effective than the traditional approach. A simple yet efficient mains transformerless solid state LED controller circuit is explained here using a single full bridge driver IC IRS2530D. Remember as we go on reducing the number of LEDs below these figures, the risk of switch ON surge increases proportionately, and vice versa. R1, R2 combined value can be calculated by the following formula, Supply voltage input minus Total LED FWD drop divided by LED current rating. hello dear mr Swagatam Majumdarfirst of all i want to thank you for making such good blog and let us know how to make incribble things.i have some question from you i hope i could have my answers.i maked this circuit and two other circiuts tooi want to choise best and the one that is smallest and taking little spacefirst of all i want to ask : can i run 20 or 18 or 38 smd leds (5730 model)on this circut?if i want to reduce leds to 18 what prameter should be change?if the leds goes up there will be changes in cureent and volatage too.but i want to this circiut delevery me 19 mA and 3.2 v for every led.you said cureent output will calculated by ractounce formula : Xc = 1/2(pi) fCif circuit eleverys 70ma out put will this burns leds?how should i controll the amp that pass leds? The two-sided circuit board seems to have been reflow soldered. If you require an improved or a confirmed surge control and voltage regulation for the LED bulb, then the following shunt regulator could be applied with the above 3 watt LED design: In the videos above I have purposely flickered the LEDs by twitching the supply wire just to test ensure that the circuit is 100% surge proof. The bulb is called the ‘load’ as it does all the work in the circuit (ie. Try with a single a capacitor first, and check the brightness, using 2 might increase the risk of switch ON surge current and LED damage. In most cases when we buy a fluorescent light it comes in a complete set with all wire connected. Led Christmas Lights As you can see in the Schematic Diagram of 2 way switch circuit below, the common of both the switches are short-circuited. Tube Light connection diagram shown here is suitable for common type fluorescent tubelight. Power Rating of a Resistor specifies the value of power that a resistor can safely dissipate. you can take the help of the following post for making it: https://homemade-circuits.com/2013/06/universal-high-watt-led-current-limiter.html. The important component (other than the LED of course) is the Resistor. The above LED control systems have their respective drawbacks and the positives in which the range of operating voltage and the number of LEDs at the output decide the efficiency of the circuit. For other lower number of LED strings, simply reduce the zener value as per the total forward voltage calculation of the LED string. This circuit can handle low voltage?? capacitive power supplies are well suited for low current high voltage type devices, 1 watt LEDs do not come under this category and therefore will not work efficiently with the above circuit. Therefore, the total current in the circuit is 3 * 30mA = 90mA. Create a circuit with 2 light bulbs in series and one light bulb in parallel. Notify me via e-mail if anyone answers my comment. Your advise is greatly appreciated. Therefore, 310/3.3 = 93 numbers, and for 120V inputs it's calculated as 150/3.3 = 45 numbers. I made this circuit but still not put in mains, before I put in mains, I want to show you, please click this link to see circuit https://drive.google.com/open?id=0B2l5VansvCMBSzZhN1MteVA1aFE, yes, according to me you can use 5D11 NTC for your application….the link is not opening because you might not have toggled the "share" option….tick the box and resend the link, hello Swagatam can you help me with a grow lamp diagram 200 LED 3 watt direct 220best regards walter, hello SwagatamPlease I need your help for a diagram for a LED grow lamp ,direct power 220 volts 4 red 1 blue all 3 watt LED , I would like to have 200 LED to create 600 watt, hello walter, I think I have answered to this question somewhere previously,anyway, you'll need an SMPS for driving 3w LEDs, you can't drive directly from 220V. You said that if you used ntc thermistor the leds would last longer. But, if there is not needed to change the brightness of the light from the same light source, here is the simple light dimmer circuit project, which is used to control the brightness of the light according to our requirement. Sir, Please describe by a circuit diagram,i don’t understand ,what is (310V / 2 watt zener diode across the supply lines after the bridge rectifier). When no light (or night) to LDR, the circuit will be closed, the lamp as the load will glow. Is this a series or parallel circuit?
