LED drivers enable smooth high/low/high beam transitions, high power for vehicle lighting apps
The A80803 leverages multi-topology conversion and patented IP to enable smooth high/low/high beam transitions in a single integrated circuit (IC). The A80804 linear LED driver provides high power for automotive lighting applications through multiple, independently-configurable channels. Both products help designers reduce the number of ICs required to create safety-enhanced automotive lighting systems, enabling higher performance […]
Managing smart street lighting design
Wi-SUN may well be the linchpin that turns street lighting into a scalable IoT umbrella offering a multitude of solutions beyond illumination. Soumya Shyamasundar, Silicon Labs According to the World Bank, legacy street lighting systems based on traditional technologies can account for as much as 65% of a city’s electricity consumption. The energy consumption, of […]
LED signaling devices increase levels of ambient light
Pfannenberg, Inc. announces the new BR50 Series Stacklight. The BR50 is the brightest stacklight available, which outshines previous Pfannenberg LEDs by 10,000 percent. The new BR50 Series Stacklight features an online configuration tool that makes it easier to design a simple stack light and provides a manufacturer’s suggested retail price (MSRP) and the resulting bill […]
Small, high-brightness RGB LEDs boast improved color mixing
Upward-lighting multicolor LEDs in the CL-V501 Series have improved color mixing, come in a small package, and exhibit high brightness. Multicolor LEDs have three dies of RGB (red, green and blue) in one package. This lets them generate various colors, including white, and are used for illumination or as indicators in many kinds of products […]
Programmable 3-kW ac-dc supplies reach 400 Vdc
Introducing the HDL3000-HV series of single-phase input 3kW AC-DC power supplies with output voltages from 150V to 400VDC, with up to 800VDC realized by connecting units in series. All models feature output voltage and current adjustment ranging from 0 to 105% using analog (via voltage or resistance) or digital (I2C, RS485, and RS232) interfaces enabling the […]
What is the difference between sensors for low UV, middle UV, and UV-C light?
Unlike visible light, which ranges between 380 nm and 780 nm, ultraviolet (UV) light wavelengths measure between 100 nm to 400 nm. UV is broken into subcategories known as UVA, UVB, or UVC. While UVC rays are the shortest and strongest, naturally occurring UVC rays are mostly absorbed by the atmospheric ozone layer, so they […]
