Tyler has worked on, lived with and tested all types of smart home and security technology for over a dozen years, explaining the latest features, privacy tricks, and top recommendations. With degrees ...

Recently, ‘Liquid crystal display (LCD) vs. organic light-emitting diode (OLED) display: who wins?’ has become a topic of heated debate. In this review, we perform a systematic and comparative study ...

If your car came from the factory with halogen or HID bulbs, you’re going to need to replace them or upgrade them down the line. Both of these bulb types lose light output over time; thus, even if ...

There’s a new type of LED in town. These light-emitting diodes (LEDs) are made from a material called perovskite, a calcium ...

If you’ve been to a wedding or a downtown coffee shop in the last 10 years, you’ve probably seen those little lightboxes that are so popular these days. They consist of letters placed ...

Red light therapy has long been used to reduce inflammation and improve skin texture, which is why LED devices are having a moment—you can reap the benefits without booking a professional treatment.

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...

This library is designed to work with the TLC5955 LED controller chip from Texas Instruments. It can also be configured to work with many other LED driver chips from the TLC59** family using the ...

This library is to control the I2C PCA9634 PWM extender. The 8 channels are independently configurable in steps of 1/256. This allows for better than 1% fine tuning of the duty-cycle of the PWM signal ...

Abstract: Thermo-mechanical reliability is one major issue in solid-state lighting. Mismatches in the coefficients of thermal expansion (CTE) between high-power LED packages and substrates paired with ...

Abstract: Heat accumulation seriously affects the photothermal performances of high-power deep-ultraviolet light-emitting diodes (DUV LEDs). In this letter, plated copper on thick film (PCTF) diamond ...
