i'm prefer driving HPL with mosfet and npn transistor, since lm317 have big power loss. Unfortunately I didn't get one at the time and it doesn't appear to be available, thus the testing I carried out. Pls help with this. http://scriptgratuit.com/led-driver/led-driver-circuit-diagram.html

All the current control is handled by the CAT4101 so even if the PIC goes haywire the led will be fine. Yes, my password is: Forgot your password? after this modification, the circuit will handle 60V with the parts listed, and you can find a higher-voltage Q2 easily if needed. If not, then where does it come from?

3. "The power dissipated by R3 is approximately: 0.25 / R3."

Where does the 0.25 come from? http://www.instructables.com/id/10W-LED-driver-and-dimmer/

12v 10w Led Driver Circuit Diagram

Is this a good idea?

Thank You

Hi there, this is a very good instructable with nice presentation.

I am planning to build constant current source #1.

Led : 10 W

Forward Voltage : 9-11 V.

Forward The closest E12 value is 3,9 ohms, it will give you a constant current of 321mA. Another test indicated that the base should be getting about 15mA when the collector is passing about 600mA. Sign in to make your opinion count.

Hi Dan

I want to connect 3 10w led chip in parallel is it ok to buy a 30w led driver to 10 Watt Led Driver Circuit Diagram Input: AC 90V--250V(10W-...10W/20W/30W/50W LED Chip + Driver Power Supply For Light Lamp Bulb 85-265V US $10.85Buy It NowFree Shipping7+ watching | 3+ soldPower: 10W. 1 x LED Driver / Only 1

Sign in 2,507 129 Don't like this video? The constant current source has a drop voltage of 3 V, so the supply voltage should always be 3 V higher than the LED voltage and can be up to 37V They are dimmed on the picture so I don't overheat them. http://www.instructables.com/id/Circuits-for-using-High-Power-LED-s/ Now I want to use it to power 4X - 4.1 Volt 700 mA LED's.

for each of the circuits i've noted at the relevant step the parts that are needed including part numbers that you can find at www.digikey.com . 5w Led Driver Circuit Diagram Ofcourse the efficiency of the LM317 circuit will get better when using more LED's in series it will always at least lose that 3 Volt x LEDcurrentYes you can, because your We will try our best to reduce the risk of the custom duties.

My concern pertains to the second set.

Today I Found Out 36,509 views 4:50 Make An L.E.D Emblem Light! - Duration: 4:31. 12v 10w Led Driver Circuit Diagram choose a resistor value at least 2x the power calculated so the resistor does not get burning hot.so for 700mA LED current:R3 = 0.5 / 0.7 = 0.71 ohms. 12v Led Driver Circuit Diagram pls help me how can it be flashing from bike.

Hi,

Wow, great article!

Can someone please tell me if the circuit in step 10 - the analog adjustable driver - is a constant

It wont take much to get this baby hot. this contact form The parts Dz, C4 and D8 turn out to be the circuit regulation network, where D8 charges C4 to the peak voltage in the freewheeling period and when D5 is forward Unloaded voltage (floating / LEDs off) less than 25V 0.5V greater than max LED (or string) voltage Less than 6V over the LED (or string) voltage when LEDs are on)  Output Im afraid i would damages the led or burn it out.. 10w Led Driver Circuit Diagram 230v

DC 30-32V 2100-3000mA 100W. If not soldering the  CAT4101 to a board make sure to coat the back side in thermal grease and physically clamp the device to a heat sink.

Type of LED strip is 3014 SMD
14,4 W/m, input voltage DC 12V, 120pcs/m, pure white color. 10w Led Datasheet you can use the extra 2.3 Amps to drive more LEDs or other electronics, if you want to.thanks AI. One method for heat sinking the CAT4101 would be to just solder the body to a square of un-etched copper clad card.

Even though a non-isolated configuration may appear a little unwanted, it reduces the constructor from winding complex primary/secondary sections on E-cores, since the transformer here is restored with a few easy

My guess is the heatsink will be plenty big. Output Current 600MA 600MA 900MA 1.5A 3A. Compatible with LED light (3528, 5050, 5630 and so on) which need DC 12V. Led Driver Circuit Schematic now that the LED's cost $3, it feels wrong to be paying $20 for the device to drive them!

Before soldering it on bend the legs of the part to match your thermal mounting. Loading... Loading... http://scriptgratuit.com/led-driver/5w-led-driver-circuit-diagram.html Please try again later.

A switched diode / capacitor combination would work quite well.

this circuit is a nonsense.

using a high power resistor is a proof of very poor efficiency !. This is the best I can do for now: http://www.ebay.co.uk/itm/ws/eBayISAPI.dll?ViewItem&item=220439870435&ssPageName=ADME:L:OU:GB:1123 iONic said: ↑ Many here often refer members to a device call a BuckPuck. Type LED calculator into google and the top link is useful.

I like how simple this is. Compatible with LED light (3528, 5050, 5630 and so on) which need DC 12V.

The first set uses six 3W LEDs (3.2-3.8V). Q2 limits the circuit in two ways:1) power dissipation. Loading...
