    • The present invention relates to a lighting device using an LED. One embodiment of the invention provides a lamp-shaped LED lighting device that can replace a known lighting device. The lamp-shaped LED lighting device promptly emits the heat generated by an LED element, which influences the optical output and the lifespan of the LED lighting device, through a lamp-shaped frame with a heat-ventilation structure that facilitates air circulation. In addition, the lamp-shaped LED lighting device prevents glare from an LED light source by using a lateral reflecting member, a diffusion lens and a diffusion cover and diffuses the light from the light source widely without optical attenuation. Another embodiment of the invention provides a tube and panel-shaped LED lighting devices that can be replaced with a previous tube-shaped fluorescent light and a panel-shaped lighting device. The tube and panel-shaped LED lighting devices rapidly emit the heat generated by an LED element, which influences the optical output and the life span of the LED lighting device, through a tube and panel-shaped frame with a heat-sink structure. In addition, the tube and panel-shaped LED lighting devices prevent glare from the LED light source by optically arranging a curved reflecting plate, a diffusion plate and a diffusion window which include a diffusion lens at the upper portion of the LED element. Furthermore the tube and panel-shaped LED lighting devices diffuse the light from the LED light source widely without optical attenuation.
