Because there are three LEDs in series, you cannot run these LEDs from a 5V supply. LED strips say “+ 12V” on them to mark the anode and this is the maximum voltage we suggest. How many amps do led lights draw. We found that 9VDC works very well even if you’re a bit dim with them .
Each segment of 3 LEDs drawn per string of LEDs, at a rate of about 20 millimeters from a 12 V supply. So for each segment, there is a maximum of 20mA draw from red LEDs, 20mA draw from green and 20mA draw from blue. If you have an LED strip on full white (all LEDs r lit) that will be 60mA per section.
How many amps do led lights draw.
To find the total maximum draw per meter, we would multiply 60mA x 10 (30 segments per meter for 30 segments / LED per meter strip) = 0.6 Amps per meter or 60mA x 20 (twenty blocks per meter for 60 / LED per meter) ) Meter strip) = 1.2 amps per meter. Then, assuming that you will have all the LEDs in one go and you are powering it from 12V. If you are going to be PWM-fading between colors, maybe you will be drawing. Still, you need a good decent power supply to run this strip, which all LEDs add!
The main problem to the number of recessed fixtures you can run at the same time is the rating of the circuit breaker that controls the circuit. Each fixture with a 60-watt incandescent or halogen bulb draws about 1/2 ampere, so a 15-ampe breaker for a standard lighting circuit will be able to handle 30 of them. It is more than the number of rooms you will set up. Each CFL or LED bulb usually gives the same light as a 60 watt incandescent bulb when drawing 10 watts or less, which is equivalent to a current draw of 1/12 amp. Thus a 15-ampe circuit can safely control 180 or more fixtures that use CFLs or LED bulbs. How many amps do led lights draw.
How many amps does a 1000w LED use?
The current in each LED is always 0.3 amp, 3 volts for 1 watt, 100 lumens. You need 1000 LEDs and probably want to connect them in series. So, the current remains at 0.3 amperes.
So, 3000 volts and 1/3 amps would be enough to produce 100 thousand lumens.
If you insist on using 120 volts, which means 168 volts DC at the output of the diode bridge and filtering capacitor, then I propose the following:
Divide 1000 LEDs into groups of 50 leads connected in series.
The circuit will be made up of 20 groups in parallel, each group made up of 50 chains.
You can connect these directly to the capacitor; The voltage will drop from 168 volts to 150 volts due to high current.
Each group is 0.3 amps, so the total current is 20 * 0.3 = about 7 amps.
So this is the end of How many amps do led lights draw.
