Beijing, China, August 1, 2013- Littelfuse, a global leader in circuit protection, has announced the launch of the company's latest products in the PLED LED open circuit protection device series. The PLEDxSW series of LED protectors are different from the black molded body PLED devices previously introduced by Littelfuse. This product is molded with white materials and is less conspicuous among LED devices, especially suitable for indoor applications. It also reflects more light at the same time, thereby improving the overall efficiency of the light engine. In the event of an open circuit failure of an LED in the LED light string, this device can provide a switching electronic shunt. The PLED device is connected in parallel with each LED in the series string. When a certain LED malfunctions and causes an open circuit, the PLED connected to it will be turned on, and the current that should have passed through the failed LED will be directed to the PLED. This ensures that the other LEDs in the light string can work normally, so only a single LED is extinguished instead of the entire light string. PLEDxSW series LED protectors are compatible with 1, 2, and 3 watt LED lights. Its small size and ultra-small package can efficiently dissipate heat, so it is an ideal choice for dense circuit board applications. Compared with previous LED open circuit protection solutions such as silicon controlled rectifiers (SCR) and Zener diodes, this product has higher reliability and lower maintenance requirements. For example, SCRs are usually bulky and require additional components such as resistors to set the trigger voltage or turn-on voltage, and their trigger voltage will fluctuate greatly with temperature. When the protected LED has an open circuit fault, the Zener diode will cause additional power consumption. This type of product is also not suitable for higher DC current, otherwise it will shorten its life or cause catastrophic failure. The standard application areas of the PLEDxSW series of LED protectors include various lighting products that use high-brightness LED light strings, such as indoor lighting, aircraft / runway lighting, and advertising signs. "Since the latest PLEDxSW series products are specifically designed for LED protection in applications requiring high brightness, high reliability and low maintenance, these products can provide circuit designers with important advantages over SCR and Zener diodes," LED Betty Li, protector product manager, said. "Another advantage of this series of products is the less noticeable molded white body. This design reflects more light, thereby improving the overall efficiency of the light engine." PLEDxSW series LED protectors have the following main design features: • The protector is less conspicuous in LED equipment; it can reflect more light and improve the efficiency of the light engine. • Even if an LED failure causes an open circuit, the remaining LED string can continue to work normally. • The standard SMB package provides layout flexibility; its maximized heat dissipation makes it ideal for dense circuit board applications. • Low maintenance requirements and high reliability. • Environmentally friendly products Availability PLEDxSW series LED protectors have a MOQ of 2,500 and are available in tape and reel packaging. Large orders are now available for samples through authorized Littelfuse distributors worldwide. For a list of Littelfuse authorized distributors, visit Littelfuse.com.
