Physicists demonstrate atomically-thin ultra-fast room temperature LED
https://www.electronics-lab.com/physicists-demonstrate-atomically-thin-ultra-fast-room-temperature-led/
Graduate researchers at the City College of New York have demonstrated a LED based on half-light half-matter quasiparticles in atomically thin materials. By Julien Happich @ eenewsled.com This is also the first successful test of an electrically driven light emitter using atomically thin semiconductors embedded in a light trapping structure (optical cavity), the researchers claim […]
Pixblasters Video LED Controller transform LED strips to huge displays
https://www.electronics-lab.com/pixblasters-video-led-controller-transform-led-strips-huge-displays/
Combine LED strips to create a huge display that acts as a regular video monitor. All this with the FPGA based RGB LED controller that is capable of controlling up to 16,384 WS2812 based RGB LEDs at 60 FPS. Not only that, but you can daisy chain multiple controllers which can control up to hundreds […]
NLM0011/NLM0010- LED Driver IC with effective NFC-PWM programming
https://www.electronics-lab.com/nlm0011-nlm0010-led-driver-ic-effective-nfc-pwm-programming/
Infineon Technologies developed the NFC-PWM series (NLM0011 & NLM0010) for fast and cost effective implementation of NFC programming for LED drivers. The NFC programming can replace the labor intensive “plug-in resistor” current setting method with the contact less NFC interface. It improves the operational efficiency and flexibility in value chain by implementing automatic programming in […]

Taiwanese startup Mikro Mesa Technology has announced a major breakthrough in the mass transfer of microLEDs, with a non-compression low temperature bonding process allowing millions of microLEDs to be transferred in one step. by Julien Happich @ www.eenewsled.com The company started cooperation with Chinese custom LCD display manufacturer Nanjing CLP Panda in 2017 and it […]
Lumileds LUXEON MultiColor Module 2.5W
https://www.electronics-lab.com/lumileds-luxeon-multicolor-module-2-5w/
LUXEON MultiColor Module 2.5W – RGBW 4-in-1 package with leading performance The LUXEON MultiColor Module 2.5W is a 4-in-1 package that makes color tuning easier. Each channel is individually addressable, enabling a large color gamut while simplifying the ability of getting just the right color point. The white LED source is located in a separate cavity to […]
LED gravity balance simulates a moving particle
https://www.electronics-lab.com/led-gravity-balance-simulates-moving-particle/
This is a nice project by Roel Arits. The project appeared on www.elektormagazine.com and you can find the source files there. This project has no practical use at all, but was initiated as an exercise in implementing physics formulas related to gravity in C-code on an Arduino. To make things visible, a neopixel LED-strip with […]
LED Engin LuxiGen™ LZ7 Six-Die LED delivers six colors
https://www.electronics-lab.com/led-engin-luxigen-lz7-six-die-led-delivers-six-colors/
LED Engin LuxiGen™ LZ7 Six-Die LED delivers six colors from a single 7mm2 package. Designed for stage, studio, and special effect lighting, the LuxiGen LZ7 adds PC Phosphor Converted (PC) Amber, Cyan, and PC Lime to the traditional Red, Blue, Green (RGB) LED color set, enabling richer and wider color combinations for more sophisticated color mixing. […]
APP NOTE: Digital potentiometer to control LED brightness
https://www.electronics-lab.com/app-note-digital-potentiometer-control-led-brightness/
Controlling LED brightness through digital potentiometer and a LED driver from ON Semiconductor. Light-emitting diodes (LEDs) require a regulated current, and their brightness is proportional to the current that flows through them. Some LED drivers use an external resistor to set the LED current. A digital POT can replace a discrete resistor with the advantage […]
