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.

Description

technical field [0001] The present invention relates to a light emitting device, in particular to a light emitting diode (LED) light emitting device having a convective heat dissipation type structure capable of rapidly dissipating heat, by using an LED element as a light source, it is possible to prevent deterioration of the light output and lifetime of the LED element and Emit uniform light without glare and light attenuation. Background technique [0002] In recent years, LED elements have been used as light sources of various light emitting devices in spotlights. Compared with known light sources, LED elements have advantages such as low heat generation, low energy consumption, long life, high impact resistance and the like. Also, in the production process, since mercury or discharge gas is not used like fluorescent lamps, LED elements have the advantage of not causing environmental pollution. [0003] Under the condition that the LED element is provided with suitable ...
