LED LIGHTING DEVICE USING STATIC CURRENT SOURCE

摘要

PURPOSE: An LED lighting apparatus in which a heat radiating effect and a light spreading effect are excellent is provided to stably drive an LED by supplying a constant current to the LED. CONSTITUTION: A supporting part(110) comprises an upper guide groove(111), a lower guide groove(112), and a seating groove. A lighting-emitting part(120) is composed of a substrate and a plurality of LEDs. The substrate is slid and combined to the seating groove. A plurality of LEDs is installed to the front of the substrate. A cover part(130) is composed of a front cover(131) and a rear cover(132). The front cover and the rear cover are respectively slid and combined to the upper guide groove and the lower guide groove. A constant current supply part changes an external power supply into a constant current. The constant current supply part supplies the constant current to the lighting-emitting part. A pair of side cover parts(140) closes the side of an LED lighting apparatus.
