LIGHT EMITTING DEVICE HAVING LIGHT EMITTING ELEMENTS |
摘要 |
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.
