LED LAMP USING ULTRA-SMALL LED ELECTRODE ASSEMBLY

摘要

Provided is an LED lamp using a nano-scale LED electrode assembly. The LED lamp using the nano-scale LED electrode assembly may solve limitations in which, when a nano-scale LED device according to the related art stands up and is three-dimensionally coupled to an electrode, it is difficult to allow the nano-scale LED device to stand up, and when the nano-scale LED devices are coupled to one-to-one correspond to electrodes different from each other, product quality is deteriorated. Thus, the nano-scale LED device having a nano unit may be connected to the two electrodes different from each other without causing defects, and light extraction efficiency may be improved due to the directivity of the nano-scale LED devices connected to the electrodes. Furthermore, deterioration in function of the LED lamp due to the defects of a portion of the nano-scale LEDs provided in the LED lamp may be minimized, and the LED lamp may have a flexible structure and shape by using the nano-scale LED electrode assembly of which a portion is deformable according to the used purpose or position of the LED lamp.
