Learn LED technology in under 90 seconds

LED Fundamentals LED is a light emitting semiconductor device similar to an ordinary diode. As forward current flowing through the P-N junction of the semiconductor material, photons are released as a results of electrons moving across the diode and falling into P- type layer. Depending on the photon’s frequency, it could either be invisible to [...]

LED Wiring Guide

LEDs are polarised with positive and negative. Before any wiring is performed, the polarity of LED should be identified. If the reverse voltage applied to LEDs is too high, it may damage them permanently. There are two types of basic LED lighting circuits: (1) Constant Voltage (CV) – LEDs are wired in “Parallel”, voltage across each LED [...]

How to Use Power Supply for Dynamic Load e.g. LED Display

If the switching power supply is connected to a dynamic load such as LED monitor, the output current will change abruptly and cause high ripple current and audio noises. A Meanwell LED power supply is recommended here, However for ordinary power supplies, we can also add suitable capacitors at the load end to improve these problems [...]
