Abstract
(EN)
A light-emitting device operating on a high drive voltage and a small drive current. LEDs (1) are two-dimensionally formed on an insulating substrate (10) of e.g., sapphire monolithically and connected in series to form an LED array. Two such LED arrays are connected to electrodes (32) in inverse parallel. Air-bridge wiring (28) is formed between the LEDs (1) and between the LEDs (1) and electrodes (32). The LED arrays are arranged zigzag to form a plurality of LEDs (1) to produce a high drive voltage and a small drive current. Two LED arrays are connected in inverse parallel, and therefore an AC power supply can be used as the power supply.

L'invention concerne un dispositif électroluminescent fonctionnant avec une tension de commande élevée et un faible courant de commande. Des DEL (1) sont formées de manière bidimensionnelle et monolithiquement sur un substrat isolant (10), tel que du saphir, et connectées en série de sorte à former un réseau de DEL. Deux de ces réseaux de DEL sont connectés à des électrodes (32) en parallèle inverse. Un câblage de pont aérien (28) est formé entre les DEL (1) et entre les DEL (1) et les électrodes (32). Les réseaux de DEL sont agencés en zigzag de manière à former une pluralité de DEL (1) permettant de produire une tension de commande élevée et un faible courant de commande. Deux réseaux de DEL sont connectés en parallèle inverse, une alimentation CA pouvant être utilisée comme alimentation électrique.

高い駆動電圧及び低い駆動電流で動作する発光装置。サファイア等の絶縁基板(10)上に複数のLED(1)を二次元的にモノリシック形成し、複数のLED(1)を直列接続してLEDアレイとする。2組のLEDアレイを互いに逆極性で電極(32)に接続する。LED(1)の間及びLED(1)と電極(32)間はエアブリッジ配線(28)とする。LEDアレイをシグザグ状に配置することで多数のLED(1)を形成し、高い駆動電圧と低い駆動電流を得る。2つのLEDアレイは逆極性であるため、電源として交流電源を使用できる。
