LED CHIPS Overview
LED Chips
SemiLEDs MvpLED chips are metal alloy devices which are made using a patented process entailing a vertical
structure. This unique approach provides superior performance at various levels.
●Thermal
benefits: The thermal benefits enable better thermal designs, light color consistency, better lifetime
and reliability
●Efficiency
benefits: The vertical structure and copper alloy p-pad, enable lower forward voltages, and better
current spreading that make for better overall efficiency
●Optical
benefits: The light extraction layer and the thin structure provide a directional light output with a
Lambertian pattern enabling better optical coupling and maximizing usable light.

The Enhanced Vertical (EV™) LED series is the latest innovation in high brightness LED chips,
lighting. Featuring SemiLEDs’ vertical chip structure on a patented metal alloy substrate and
manufactured with our proprietary process, the EV LEDs offer advantages in excellent optical output and
high thermal conductivity, thereby achieving greater light quality, color consistency, reliability and overall
efficiency of the luminaire. Further
design advances of the EV LED structure, offer higher thermal endurance for process temperatures up to
325°
Celsius and maximum suggested junction temperature of 150° Celsius.
