The present invention relates to an LED lighting device comprising: a plurality of bare chip LEDs disposed tightly together on a PCB; a molding portion provided on top of the bare chip LEDs and emitting light from the bare chip LEDs in a specific light distribution pattern; a case providing an installation surface on which the PCB is installed, provided with a light emission hole through which the light from the bare chip LEDs is emitted externally; and a plurality of heat dissipating fins provided in plurality on the outer surface of the case, and disposed projecting in an elongated manner from the light emitting hole to the outside of the installation surface. The present invention can diffuse high-output light even from a small surface area by using highly integrated bare chips, and can increase heat dissipating efficiency by tightly fixing a heat dissipating portion including heat dissipating fins directly on a metal substrate. Thus, by easily discharging heat generated by a highly integrated light source, the present invention has the effect of preventing the service life of the (LED) light source from being shortened. |
