1. An LED lighting apparatus comprising:
- a main cover with an elongated pipe shape having a cross-section formed of a closed curve line and both ends of a length direction formed to be open, the main cover accommodating an LED and a driving circuit unit driving the LED;
an external frame sliding-coupled to an external surface of the main cover along a length direction of the main cover;
an inner frame having a shape extending in a direction parallel to the length direction of the main cover and sliding-coupled to an internal surface of the main cover along the length direction of the main cover to be positioned at the inner space of the main cover; and
a close-and-seal cover closing and sealing both open ends of the main cover to close and seal the inner space of the main cover,wherein a bottom surface of the inner frame supports an LED substrate including the LED, and top surface of the inner frame supports the driving circuit unit,the close-and-seal cover is coupled to the external frame and the inner frame,an insertion groove that is concave in an inner direction at an upper side of the main cover is integrally formed with the main cover,the external frame includes an insertion protrusion corresponding to the insertion groove,the external frame is sliding-inserted to the upper side of the main cover to be coupled such that the insertion protrusion is coupled to the insertion groove,a first coupling hole is formed at both end sides of the external frame in the length direction,a second coupling hole is formed at both end sides of the inner frame in the length direction, andthe close-and-seal cover is coupled to the external frame and the inner frame by a fastening member coupled to the first coupling hole and the second coupling hole.
