LG Innotek Develops Driver on Board LED Module For Lighting
LG Innotek, a leading global materials and components manufacturer, today announced that the company succeeded in developing a DOB (Driver on Board) LED module whose convenience and performance have sharply improved. The DOB LED module integrated the switched mode power supply (SMPS) on its board.…
The early stage of AC Direct modules integrated a current-controlling driver IC in the module which controls the current and voltage, but it has difficulty of the detailed and stable power source management. The DOB LED module has very low flicker. Flicker percent is 20% or less at all dimming range, which is about 60% lower than AC Direct module. This product also provides efficacy of 140 lm/W, the best performance in 9 W category (CRI is above 80), which is 30% higher than AC Direct module.
The LED industry believed that, if the SMPS is integrated into the LED module, the heat from the LED chip and the SMPS would be transferred to the whole module, reducing the stability and efficiency of the lighting and decreasing its lifespan. LG Innotek, however, developed its proprietary circuit design technology and heat-sink design to improve product performance and lifespan. Its lifespan has also increased up to 50,000 hours.
The company will showcase this module at the Light + Building 2016 trade fair in Frankfurt, Germany from March 13 to 18. LG Innotek will be available for meetings at Light & Building 2016 at booth B30 located in Hall 6.2.
