Abstract :
The paper studies the technologies to improve the quantum efficiency of light-emitting diodes (LEDs), and designs new LED structures from the theory and software simulation. Including new LEDs with anti-membrane and truncated-inverted-pyramid (TIP) chip. Then we try to design a new kind LEDs with the two ways together. Their relative improvements of luminous efficiency are 16.8%, 26.933% and 47.198 %.These studies provide effective data and design methods to improve the efficiency of quantum LED.
