Development of LT-12/LT-13 Series of LED Lighting Connector (COB Type) with Improved Assembly Workability and Reliability to Add to our Existing Product Lineup

　　　　　
　We are pleased to announce that we have developed and released the 'Chip On Board' (COB Type) LT-12/LT-13 Series of LED lighting connectors. We have also increased the number of LED compliant with the LT-10/LT-11 Series released in March last year, increasing our lineup of products.
　Due to SMK's unique structure, this connector has excellent heat dissipation qualities, which is essential to deliver superior LED performance. An LED is inserted between the connector's upper and bottom covers, and is fixed with a screw to the heat sink. This structure not only achieves a stable dissipation effect, it also helps to improve assembly workability and reliability. (Patent pending)
　In addition, in compliance with the Electrical Appliance and Material Safety Act and JIS IEC etc., sufficient creepage distance is secured to ensure high reliability and withstand voltage.

Date Released	2014/01/10
Release No.	1000cs
Product Name	Connectors for LED-COB Module 「LT-10/11/12/13 Series」
Features	1) Its structure is composed of upper and bottom covers within which a COB type LED is inserted. 2) LED heat is dissipated to the heat sink by the thermal conducting sheet inserted in the lower cover. 3) When installing the LED there is no need for preceding processes such as applying heat conduction grease or attaching an insulation sheet, helping to improve assembly workability and reliability. 4) Secures a spacious creepage distance series connection for multiple LEDs in series and as a countermeasure to lightning surge. 5) The power supply section uses a snap-in contact to realize easy and secure electric wire connection. 6) Complies with JIS/IEC standards and the Electrical Appliance and Material Safety Law.
