Thyristor Power Control Devices from Littelfuse Expand Usable Range of Lighting Spectrum for LED, CFL, and Incandescent Loads

Thyristor Power Control Devices from Littelfuse Expand Usable Range of Lighting Spectrum for LED, CFL, and Incandescent Loads
Littelfuse, Inc has introduced the Q6008LH1LED and Q6012LH1LED Series of Alternistor Triac and Q6008LTH1LED and Q6012LTH1LED Series of QUADRAC Thyristor Power Control Devices. These devices are designed for use as the switch in a dimmer circuit to adjust the light output of Light Emitting Diode (LED) bulbs and strings. They allow designers of AC line based dimmers for LED lighting to accommodate a wide range of operating parameters without sacrificing reliability and without degrading the performance of the dimmer. As a result, a single control device can be used for LED-based dimmers or for combination dimmers designed for incandescent, compact fluorescent lamp (CFL), and LED loads.

Phihong LED Drivers Exceed Expectations with 100,000 Hour Measured Lifespans

Phihong USA has developed a new series of external AC/DC LED drivers that feature extended lifespans of up to 100,000 hours. The new Stonehenge series LED drivers are designed without E-caps, which dry out over time and shorten the operating life of power supplies. A subset of the broader PDA012X Series, the Stonehenge Series consists of two drivers: the PDA012A-350C-H-R, which is designed for AC inputs of 220-277VAC, and the PDA012B-350C-H-R, which is designed for AC inputs of 100-120VAC. Both 350mA constant-current drivers operate at an output voltage range of 10-43VDC, and are ideal for applications including display lighting and small strings of high-intensity bulbs.
