The present invention relates to a light emitting diode (LED) lighting device. The LED lighting device according to the present invention is characterized in comprising: a head portion (100) which is composed of a base frame (10), which includes a slot (12) on which an LED package (110) is installed, and a cover frame (20) which is installed on the base frame (10) to form a compartment (22); a through hole (30) which is formed on at least one of the base frame (10) and the cover frame (20), wherein the through holes (30) are provided on multiple places to communicate with the compartment (22); and a net unit (40) which finishes the through hole (30) and is made of a synthetic resin yarn including a mono filament yarn, wherein a density of the net unit (40) is 20-60EA/inch and an aperture size thereof is 400-700um. Therefore, according to the present invention, since a heat radiating net is made of a material including the mono filament yarn with the density of 20-60EA/inch and the aperture size of 400-700um, foreign matters including small flying insects are tightly blocked, and contamination of an inner space of the compartment is prevented while heat radiating efficiency due to air ventilation is enhanced. In particular, when it rains, rainwater permeation is improved and a water-cooling effect is enhanced. Also, since the inner space of the compartment can be cleansed with water, degradation of the heat radiating efficiency can be prevented even after a long time use. |
