Zusammenfassung:	An LED illumination device with a structure for reducing a dark part is disclosed. The LED illumination device with a structure for reducing a dark part according to the present invention includes: a main body in which a plurality of LEDs are disposed on a front surface of a circuit board; a transmission cover provided in front of the plurality of LEDs; and a reflector which forms a first reflection surface between the LEDs, wherein the center of the orientation angle of the LED is directed to a point of the shortest distance from the transmission cover, and light of the LED reflected on the first reflection surface is directed between the points of the shortest distance. Accordingly, the present invention can provide the LED illumination device with a structure for reducing a dark part, capable of improving light quality by removing a hot spot and the dark part while slimming a thickness thereof and reducing the number of LEDs. 암부 개선 구조의 엘이디 조명기구가 개시된다. 본 발명의 암부 개선 구조의 엘이디 조명기구는, 회로기판의 전면에 다수의 엘이디가 배치된 본체; 다수의 엘이디 전방에 구비되는 투과커버; 및 엘이디 사이에 제1 반사면을 형성하는 리플렉터를 포함하고, 엘이디의 지향각 중심은 투과커버와의 최단거리지점을 향하며, 제1 반사면에서 반사된 엘이디의 빛은 최단거리지점의 사이를 향하는 것을 특징으로 한다. 본 발명에 의하면, 두께를 슬림화하고 LED 개수를 절감하면서도 Hot-spot 및 암부 발생을 제거하여 광품질을 향상시키도록 이루어지는 암부 개선 구조의 엘이디 조명기구를 제공할 수 있게 된다.
