DEAWANG SYSTEM CO.,LTD in the Republic of Korea, Daegu air purification system in the West Division, LED wingka Systems Division, LED lighting iteupnida divided into divisions. Air purification systems are clean room air with a device wants to keep the air inside and outside of the detection of carbon dioxide, carbon monoxide, formaldehyde, fine dust, temperature and humidity, but represents the size of the palm, and communicate wirelessly with both the internal controls and communications in connection with all machines and air conditioning ventilation systems in buildings with fully automated intelligent air qualitywithin the air quality is better than the outside of the case fan to force outside air flows into and through the internal forced air ventilation exhaust to come in the building Wingka LED and battery system (batteries) to distinguish between day and night, through the night, so the only light came in shiny patent product. These products are earrings, necklaces, bracelets, people, clothes, appliances, etc. can be attached to the fashion market is estimated shall be possible to develop new markets. Market value of more than 1 trillion market looked ahead, endless markets and market advantages such as preemption and is also said making thin, low cost through simple materials available in a variety of variations. Great LED lighting is low voltage and 5V low power between 10W ~ 15W proud and touched by human hands, or even short lines do not cause electric shock or fire is proud. And reduce electricity costs and benefit the environment and contribute to carbon reduction. The unique characteristic of the low-voltage LED drive circuit and power generation to make use of high-temperature treatment was to solve heat dissipation, low power usage, save your life up so that the benefits were implemented. LED lighting focused on investments in all business sectors, and also with global partners and expand the global market for all parties
