SMK Improves Connectors for COB LED Module
by Making Them Halogen-free and UL Certified

   SMK Corporation has improved its current connectors for Chip On Board (COB) LED module to enhance customer convenience.

① SMK has produced COB connectors with UL94 HB flame retardancy
   by using halogen-free molding materials.(Among the halogen
   elements, bromine is said to affect the lifetime of the LED.)In addition,
   the company is due to commence mass production of UL94V-0 products
   with the halogen-free molding materials by the end of this year.
② All series of connectors for COB LED module have newly been certified
   according to UL 8754, helping customers to eliminate man-hours for
   acquisition of the certification. (As a lightning surge measure, a
   sufficiently spacious creepage distance has been secured in compliance
   with the IEC and JIS standards, achieving safe breakdown voltage.)
③ Product lineup was expanded with connectors using silicone heat-
   dissipation sheets, which provide a stable heat dissipation performance
   toward COB LEDs whose output had rapidly increased.

   The connectors are composed of top and bottom covers within which a LED is inserted. LED heat is dissipated to the heat sink by the thermal conduction sheet integrated to the bottom cover.
   It requires no preliminary processes such as applying thermal conduction grease or attaching thermal conduction sheet, improving assembly workability and reliability.
   The power supply section uses a snap-in contact to realize easy and secure electric wire connection.
