N-channel power MOSFETs target automotive load switching in LED drivers
The expanded of automotive N-channel power MOSFETs from Toshiba includes the 60V SSM3K341R and the 100V SSM3K361R. Housed in small SOT-23F packages, the new MOSFETs feature low on-resistance and are suited to load switching in LED driver applications, including automotive dashboard meters and headlights and LED TV backlights. Increasing demand for power-saving LEDs has led to […]
Waterproof LED drivers include PFC
The PWM-120-12DA / PWM-120-24DA is a constant-voltage-output design meeting Digital Addressable Lighting Interface (DALI) control system standards IEC62386-101,102,207. Suitable applications include LED commercial, office lighting, and indoor LED decorative lighting. The constant-voltage PWM style output is at 1.47 kHz. The constant-voltage PWM mode maintains color temperature and brightness homogeneity when driving different styles of LED […]
World’s First 3D robotic LED sign brightens up Times Square
Coca-Cola recently unveiled a new six-story digital sign in Times Square featuring 1,760 independently moving LED screens, choreographed to the content on display. Coke says Guinness World Records was on hand for the sign’s debut and awarded The Coca-Cola Company two record titles: The Largest 3D Robotic Billboard and The First 3D Robotic Billboard. Few […]
UV-C LED at 70 mW, said to be most powerful ever
LG Innotek, UV LED partner of LASER COMPONENTS, announces the first 70mW UV-C LED in the world. At 278nm, it features the highest power ever achieved from a single chip.Its improved light emission capabilities derive from a newly developed semi-conductor technology. Thanks to its robust 6x6mm SMD casing, it can be used in almost any […]
Low-profile two-color chip LEDs are ultra-compact
The industry’s smallest class (1608 size) of two-color chip LEDs, dubbed SML-D22MUW, features a special design that improves reliability along with a backside electrode configuration that supports high-resolution displays. Conventional numerical displays use a single color to indicate numbers, but there is a growing need to change the color to make it easier to recognize […]
