Displays sport LED control, external LED lighting around their edges
DATA MODUL now offers two fully pre-configured monitor solutions including external LED lighting around the display edges and LED control – not to be confused with display backlight. The monitors are available with 27″ and 31.5″ display diagonals and are also equipped with a cover glass and optional suitable PCAP sensor. This custom lighting solution […]
Low-voltage automotive LED backlight drivers incorporate boost converter
Maxim Integrated Products, Inc. introduces the four-channel, low-voltage MAX25512 automotive LED backlight driver with an integrated boost converter. It is the only integrated solution that retains the full, constant brightness of in-car displays even during extreme cold crank conditions down to 3V input voltage. The single-chip LED driver eliminates an external MOSFET and current sense resistor and […]
LED enables efficient system designs using new phosphor
AMS-OSRAM is expanding its comprehensive horticulture portfolio with the Osconiq S 5050. There is an ideal light recipe for each plant that includes “ingredients” such as the required wavelengths, intensity, average illumination duration, and much more. Operators of greenhouses and so-called indoor farms naturally want to be as energy-efficient as possible in addition to maximizing […]
LED drivers designed to enhance performance of connected lighting systems
ON Semiconductor has announced two new devices designed to enhance the performance of connected lighting systems. The NCL31000 and NCL31001 LED drivers to allow manufacturers to develop LED luminaires with light-based positioning technology and visible light communication. By adding data intelligence and accurate positioning (up to 30 cm), these solutions will revolutionize lighting in a […]
Spring-loaded pins simplify PCB daisy-chaining
Mill-Max Mfg. Corp. has developed a versatile line of horizontal surface-mount (HSMT) spring-loaded pins designed for making low profile connections parallel to the board surface. These spring-loaded pins have plunger travel in-line with the board surface, making them ideal for end-to-end board connections in assemblies with restrictive height requirements. This family of HSMT spring-loaded pins […]
Next L-Prize announced: This time, it’s commercial LED lighting
The DoE-sponsored competition that gave rise to the first economical 60-W LED bulbs is operating again. The new goal: More innovative commercial lighting. The Bright Tomorrow Lighting Prize (L-Prize) began in 2008 with the goal of accelerating development of LED-based replacement lamps that met extraordinarily-stringent performance and life goals. Back then, there were such things […]
The difference between LEDs and photovoltaic cells
LED’s and photovoltaic cells play increasingly prominent roles in our world. Both are semiconductor diodes. The LED or light-emitting diode emits light while the photovoltaic cell converts light to electricity. The LED is a diode that emits light only when forward-biased. Under a forward voltage bias, electrons cross from the n-region and recombine with the […]
Super-small white-chip LEDs feature high luminous intensity
ROHM Semiconductor introduced their new CSL1104WB ultra-compact, high luminous intensity white chip LEDs. The products are optimized for applications requiring high brightness white light emissions, such as IoT devices, drones, and other battery-equipped applications. In recent years, high luminous intensity (2.0cd) white LEDs have been increasingly adopted to improve visibility in a range of applications […]
Project: Implementing a 4xN LED driver
by Dialog Semiconductor LED displays are widely used in systems ranging from digital clocks, counters, timers, electronic meters, basic calculators, and other electronic devices capable of displaying numerical information. Figure 1 depicts an example of a 7-segment LED display which can show decimal numbers and characters. As each segment on the LED display can be […]
