The present invention relates to an LED luminaire having a light-diffusing function, and more specifically to an LED luminaire having a light-diffusing function, including: a main body having a volume corresponding to a preset thickness, width, or diameter and an open front side; a printed circuit board on which multiple LEDs are arranged in the longitudinal and transverse directions and which includes an embedded LED drive circuit and is detachably installed inside the main body; and a front diffuser plate which is installed in the opening of the main body to evenly distribute light emitted from each of the multiple LEDs over a certain area, wherein a reflector member with a certain area is formed or mounted on the printed circuit board positioned around the LEDs, and a light-diffusing cap, which is made of transparent resin film or reflective film and shaped into a dome with a light diffusing angle from 150 to 170 degrees, is detachably installed to surround each of the LEDs and the reflector member formed or mounted around the LEDs. According to the present invention, it is possible to reduce the number of LEDs installed in an LED luminaire having the same area and light output, and reduce the overall thickness of the LED luminaire, thereby producing a slim LED luminaire and significantly saving the manufacturing costs. Moreover, it is possible to cut the installation costs since the LED luminaire of the present invention may be installed on a ceiling without punching the ceiling, and especially, to prevent local shades and spots, thereby remarkably improving merchantable quality and reliability of the product. |
