Beijing, March 19- Littelfuse, a global leader in circuit protection, has launched Q6008LH1LED / Q6012LH1LED series triacs and Q6008LTH1LED / Q6012LTH1LED series QUADRAC thyristor power control devices. These devices are designed specifically for use as switches in dimmer circuits and are responsible for adjusting the brightness output of light-emitting diode (LED) bulbs or tubes. This series of products can help designers of LED lamp AC line dimmers to meet various operating parameter requirements without sacrificing reliability or reducing dimmer performance. Therefore, a single control device can be used for LED dimmers, or for combined dimmers designed for incandescent lamps, compact fluorescent lamps (CFL) and LED loads.
"For designers of ambient lighting or theme lighting fixtures, the advent of LED lighting has brought several major technical challenges. For example, these new light bulbs and tubes have extremely low actual currents, so traditional thyristors will be turned off in advance, thus A certain range of lighting spectrum cannot be used, "said Corey Deyalsingh, product director of the Littelfuse thyristor power control device product line. "The low load current characteristics of these new thyristors make it possible to create a single dimmer design suitable for all dimmable lighting loads (LEDs, CFLs, and traditional incandescent lamps). These thyristors during turn-on and high junction temperature ratings (Di / dt) high current rise rate can ensure greater reliability and design flexibility. Our new Q6008LTH1LED and Q6012LTH1LED series QUADRAC devices combine two-terminal AC switching elements and triacs in a single package, Therefore, the circuit design and assembly process can be further simplified. "
Alternistor triac (Q6008LH1LED and Q6012LH1LED series) and QUADRAC (Q6008LTH1LED and Q6012LTH1LED series) thyristor power control devices can provide the following key functions and advantages:

With a constant current of IC, the working voltage of the IC is 12-24V. As long as the voltage is not lower than the rated voltage, the current of each led beacon will be consistent.It is made of high-brightness LED (LED is made of imported chip---high brightness, good electrical).
No pressure drop can be achieved over a specific length and voltage.Suitable for urban lighting projects,home decoration, bars, dance halls, cars, indoor/outdoor advertising and interior and exterior contours of various high-end venues
