Abstract

Provided is an LED fluorescent lamp. The LED fluorescent lamp comprises: a heatsink which has a set length and has a semicircular shape formed with attachment recessed parts at both ends; a diffusion tube which has a set length and has a semicircular shape of which both ends couple by hooking onto the attachment recessed parts; and an LED substrate which has a set length, and of which the two side parts are inserted and secured in securing recessed parts formed on the insides at both ends of the heatsink, and in a plurality of positions on the upper surface of which LEDs are mounted in such a way as to be exposed to the diffusion tube. Consequently, the present invention allows easy hooking attachment and detachment of the heatsink body and the diffusion tube having a set length and having a semicircular shape, and, in addition, the light emanating from the LEDs can be uniformly diffused, and the heat generated from the substrate which has a set length and from the LEDs mounted on the substrate can be rapidly discharged to the outside.
