Consumption (depending on the type and number of LEDs)- 60 SMD 3528 LEDs per meter – 5 W per meter strip. – 120 SMD 3528 LEDs per meter – 9 W per meter strip. – 60 SMD 5050 LEDs per meter – 14.4 W per meter strip. – 72 SMD 5050 LEDs per meter – 17.3 W per meter strip.
How to supply power to an RGB LED?
Power supply. Power supply: Most LED strips are usually powered by a 5V, 12V, or 24V power supply. The required current depends on the LED strip’s length and the LED’s density.
How much does a night light consume?
Night lights for children: how much power do they consume? If you’re wondering whether a light that’s on all night will drive up your electricity bill, you’re wrong. Thanks to the new LED lights, this problem can be avoided. The consumption for the basic models is about 1 W.
Where to place the resistor?
Well, the resistor can be placed anywhere; it doesn’t matter if it’s before or after the diode. In any case, it will do its job, which is to limit the passage of current in the circuit.
How is a COB LED supplied with power?
Special drivers are used for this purpose, which converts traditional sources (e.g., 12 V from a power supply) into variable voltage sources (e.g., with fluctuations between 10 and 30 V), but with a current limit (e.g., 900 mA for connecting a 10 W COB).
What does a series connection look like?
The loads can be connected in series or parallel. A series connection is when each bulb (load) is connected with the others on the supply line, creating a single path for the electric current flowing through it.
How to find the positive terminal?
If a current is flowing in some wires, you can quickly determine if they are negative or positive with a tester. Place the negative side of the tester to the ground and test the wires with the positive side of the tester: if it reads 12 volts or so, it’s positive; if it reads nothing, it’s negative.
How to recognize LEDs?
Usually, the bulbs we find have an „E” socket followed by a number indicating their diameter in millimeters. To recognize an LED bulb, we must also know its wattage, which does not depend on the socket type, but on the wattage indicated by the letter „W.”
How to eliminate the error of LED light bulbs?
To fix the controller’s error (or Canbus error, as some say) or restore the correct flashing frequency of the turn signals, it may be necessary to install a resistor in parallel with the LED bulb.
