|Feature Define||Low Voltage Discharge
Liner light. Good for large wattage application.
|Lighting Emit Diode
Spot light. Usually for signboard, decoration applications.
|Technology||Research and develop in 2000, sell in 2003,in a position of new leading light source. Standardized product can fully meet the market need, suitable for large scale production.||The first red light LED was developed in 1968.Since then, its been 40 years. The first white light LED was in 1996.Invest risk high for technology update too fast. Not suitable for functional lighting project. The whole growing process is slow.|
|Market potential||LVD can replace most of conventional light sources in functional lighting fields, so its potential market is huge.||LED has developed for many years, but limited to traffic signal, vehicle rear light, LCD panel back lighting, display in lower wattage because of the low light efficiency, low power factor, scarcity of accommodated fittings.|
|Economy||With the development of large scale production, LVD cost will be lowered to the same level of traditional lights or even lower, then it will be widely used.||High cost, difficult to be widely used in some fields, limited in certain market.|
|Energy saving||LVD efficacy is as 30% as higher than LED, with lower depreciation.||Lower efficacy, lower power factor, high depreciation and heat output, not as saving as LVD. Semi-conductor technology consumes more energy during production.|
|Application||Industrial, commercial, street, tunnel, bridge, garden, agriculture, Ad. …||Traffic signal, vehicle rear lights, cell phone display screen etc. Limited in functional lighting projects.|
|Reference||LVD has been widely used in various lighting projects. It is proved that LVD has big market potential, industrialization speed with scale effect.||LED is drawn back by its technological problems. Probably another 5-10 years to go before it is industrialized and scaled.|
