With new LED lights, one of the most difficult, demanding, and costly sections of a design is thermal management. Without sufficient thermal management, the results can be catastrophic, ranging from ...

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

Light-emitting diodes (LEDs) have been gaining popularity in consumer electronics and automotive lighting, and now LED lighting is emerging as a potential replacement for the standard incandescent ...

This module introduces Pulse Width Modulation (PWM) techniques for Python on the Raspberry Pi. Subsequently, by using PWM we can modify the brightness of an LED without having to change a resistor.

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...

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 ...

There are a number of ways to efficiently and elegantly limit an LED’s brightness, but [Tommy] found that using a light pipe or diffuser can integrate better with a device, especially when the device ...

Once upon a time, buying a lightbulb meant choosing an incandescent one of between 25 and 100 watts, depending on how bright you wanted the light to be and the fixture you were putting it in. You ...

TCL just unveiled a new TV in its Precise Dimming Series. The QM7K is a Mini-LED TV and a follow-up to the recently-released ...

TCL®, one of the world's best-selling consumer electronics brands, and leading manufacturer of display technology, today ...
