An angle-adjusting LED lighting apparatus includes an LED light source on which LEDs and a printed circuit board electrically connected to the LEDs are mounted. A lens diffuses light illuminated from the LEDs, and a case houses the LED light source and the lens. At least one portion of an outer surface of the case is circular-shaped, an uneven part is formed at the circular-shaped outer surface of the case, and an engaging groove is formed inside the uneven part and penetrates the case along a length of the case. The apparatus includes an angle-adjustment member having an uneven surface that engages with the uneven part on one surface, and an engagement fixing member that engages with an outer fixing member on which the lighting apparatus is to be mounted using an engaging member. The engaging member penetrates the angle-adjustment member and is inserted into the engaging groove. |
