In order for LED to replace various lamps that we use daily, not only LEDs efficiency must increase, but also its cost to be reduced. Diamond is LEDs best friend with highest thermal conductivity that can effectively cool LED so more light can be released. Diamond-like carbon (DLC) can be coated on both LED chips and metal-cored printed circuit board (MCPCB) so chip-on-board (COB) packaging with DLC to DLC bonding is possible. This can brighten LED luminaries and extend their service longevity. Moreover, the fabrication of LED lamps become simple so one dollar may buy finished lamp of more than 200 lumens. The widespread installation of LED luminaries can make our living more comfortable. Additionally, the reduced electricity used for illumination can reduce significantly CO2 released in air, an effective way to cope with the global warming problem. /Key Words (Light Emitting Diode; LED) (Diamond-like Carbon; DLC) (Lighting) (Diamond) LED LED 2012 LED LCD LED
