Marl's LED beats fluorescent on efficiency
New low-watt Citizen LED light engines from Marl enable the creation of replacements for fluorescent strip lights – offering well over 25% better efficiency and at least four times longer lifetimes. An array of five of the chips matches the light output of a 1.2W fluorescent tube.
Marl adds pink version to LED family
Marl has taken the unusual step of adding a pink version to its 676 series of standard indicator LEDs. These rugged IP67 sealed LEDs are extremely popular for panels and status indication applications due to their wide viewing angle.
ON Semiconductor Introduces RGB LED Pixel Drivers
ON Semiconductor has expanded its line of constant-current, LDD™ (low dropout driver) products recently acquired from Catalyst Semiconductor, to include two new high-brightness RGB LED pixel drivers. The CAT4103 and CAT4109 are three-channel, linear-based constant-current LED drivers for RGB LED pixel control in emerging high-brightness, high-visual impact LED architectural lighting.
ON Semiconductor's 4A Single-Chip Driver for Supercapacitor-Based LED Camera Flash Applications
ON Semiconductor has introduced a 4A supercapacitor LED flash driver. The new CAT3224 addresses the emerging requirements for true high-intensity LED flash capability in high megapixel camera phones and standalone camera applications. The device is highly integrated with all the functions necessary to accurately control LED flash charge/discharge, including power switches capable of sourcing up to 4 amps, as well as providing the charging functio...
New High-Power Infrared LED for Spectrophotometry and Moisture Detection Applications
Hamamatsu Photonics introduce the new L10660 extended Infrared LED, the latest in their current range of high quality Infrared LEDs. Featuring 2.6 times the radiant output power of the conventional type (L7850), the L10660 was developed using MBE (Molecular Beam Epitaxy) technology to create LEDs with multiple quantum wells in the active layer.
