High power LED lighting is harder than it looks. Power, dimming, control, and communication collide in one design.

Scarcely a lighting application exists that designers have not considered converting to solid-state lighting, especially as LEDs by leaps and bounds improve both the quantity and the quality of their ...

Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...

A boost+buck two-stage LED driver is well suited for non-isolated applications in the 50 to 250W power range, offering a viable alternative to more expensive isolated LED drivers. Electrical isolation ...

Fig 1. This voltage regulator circuit (a) uses green LEDs as both the stabilization elements and as the voltage indicators at the front-panel switch (b). Fig 2. The addition of resistor R4 to the ...

This is a fairly long post, so bear with me- I just want to be clear on everything. It would be easier with pics, but unfortunately I'm at work. There are actually 2 somewhat related questions. I know ...

For several years manufacturers have been introducing LED bulbs onto the market with the eventual goal of replacing incandescent and CFL lamps. The design of these lamps has evolved from very simple ...

In this article, I would like to talk a little bit about LEDs, including why they will become the lighting source of choice, how to power them and also, how to protect them from the hazards they face ...

I have a Vinsic VSPB304 powerbank which has three outputs - two USB-A (rated at 2.4A each) and one USB-C (rated at 3A). All three can be used at once but the maximum combined output is 5A. I want to ...
