The present invention relates to a fluorescent lamp-type LED lighting device including: a case part formed to be elongated in one direction and having an open bottom surface which provides a reflection space on the inner side; a cover part provided on the bottom surface of the case part so that the light which is reflected and diffused in the case part is emitted; and multiple LEDs which emit the light from the cover part and the inner side of the case part such that the light is reflected and diffused on the inner side of the case part. According to the present invention, the LED light is emitted toward an indoor ceiling side, the reflection space is provided so as to reflect and diffuse the emitted LED light, and the light is emitted through a bottom surface part. Accordingly, no additional diffusion plate for surface emission is used and thus optical efficiency can be increased.

Fluorescent lamp-type LED lighting device

An LED lighting device includes a case unit forming a light emitting space, wherein resting surfaces are formed at predetermined areas on the inner side of the case unit, substrates having LEDs mounted thereon and respectively rested on the plurality of resting surfaces, and heat-dissipating units formed in the outer side of the case unit for heat dissipation. Lifespan and user convenience can be improved.
