LEDs with Flip Chip Technology
In 2019, GMKJ is launching new LEDs with flip chip technology. Flip chip technology is relatively new and involves mounting the chip upside down in the LED housing (in relation to so-called Epi-Up). The design of the chips improves heat dissipation, which will further reduce energy consumption with up to 20% less energy consumed compared to current LEDs. The LEDs also preserve the long luminaire lifespan of 100,000 hours without light depreciation. The new flip chip LEDs are being launched primarily for luminaires in segments where lighting is seldom replaced, positioned high up on ceilings, or in use around the clock.
