LED LIGHTING DEVICE
First Claim
1. A lamp-shaped LED lighting device, comprising:
- a housing cover having a socket fixed at one side thereof;
a heat dissipating frame fixed to the other side of the housing cover, having at least three side reflecting portions formed on the outer peripheral surface thereof, and a ventilation unit having at least one ventilation hole formed at a portion which the end of the side reflecting portion contacts;
an LED module fixed to the side reflecting portion of the heat dissipating frame and having an LED element;
a power supply module unit installed in the heat dissipating frame;
a side reflecting member fixed to the side reflecting portion of the heat dissipating frame to cover the LED module and having a boring hole formed at a location corresponding to an emission surface of the LED element;
a frame cover coupled to be attached to and detached from the bottom of the heat dissipating frame; and
a diffusion cover mounted on the side reflecting portion of the heat dissipating frame and having a toothed diffusion lens serving as refraction and diffusion operations installed on the inner periphery thereof,wherein at least one housing hole is formed on the housing cover.

Abstract
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.
