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 ...

Most small-size color LCD displays today use white LEDs for backlighting. These systems usually involve handheld devices with an LED drive circuit powered by a battery whose output voltage varies over ...

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 ...

Peter Green explains advantages of LED drivers based on the flyback power-supply topology: They're inexpensive; they provide an isolated output that complies with UL safety requirements; they make it ...

Recent breakthroughs in LED technology have enabled LEDs with a broad spectrum of light output to be produced and not just the traditional red and green derivatives. Hence the sheer numbers of LEDs ...

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

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 ...

Advanced LED lighting arrays can spectrally tune their output wavelength to highlight different features and defects in captured images. The capability enables a single light fixture to quickly adapt ...
