Donut pendant / LED Lighting

Donut pendant

" Donut Pendant " is pendant type of LED lighting which has feature of very slim design less than 1cm thickness.
We make product using a radial LGP (light guide plate) that light passes from inside to outside and is in international patent pending currently. This technology is first attempted in the world and has very thin thickness of the outer by passing the light from middle to outer unlike passing light from outside to inside. In addition, it is free to change size and design of the outer by installing lighting facility in the middle of frame.
Using edge type of LED system, environment-friendly and glare less.
