What is a lamp driver?

The LED lamp driver manages the input voltage and current according to the voltage and current level of the lamp, and provides the current required by the lamp to drive one or more LEDs. The advantage of LEDs is that they do not need a lot of power to make them run. LED actually relies on a DC power supply to work at a fairly low voltage (usually between 2V and 4V per unit). Therefore, the slim le...

How to choose suitable led power supplies for project?

All led power supplies are either constant voltage (CV) or constant current (CC) or both. This is one of the primary factors you need to consider while you are choosing a suitable one for your project. Normally to say, LED Downlight, Residential LED Lighting, Retail Lighting, Mood Lighting will use constant current led driver. Moving Signs, Stage Lighting, Architectural Lighting, strip l...

How many LED strips can you connect?

Electrically speaking, every 5 meters must be connected in parallel, but physically speaking, they can be arranged from beginning to end until about 20m (it may cause a voltage drop and cause the brightness of the lamp to dim). For example, if you want the led power supply waterproof to drive your 15m LED strip. You can do: Firstly, you could connect 10m wires to the led power supply waterproof. S...

What is voltage drop?

When using a high efficiency led driver to drive multiple lights in a house, we often encounter a voltage drop, so what is the voltage drop? Voltage drop is the decrease in voltage when current flows through various components of the circuit. If we connect the wires from the local e-commerce to the home. Under ideal conditions, current flows unimpeded along the wire until it reaches our house. The...
