UV LED curing light source spectral range is narrow, effective wavelength radiation efficiency is high. UV curing light source is relatively narrow, and the half width is only a dozen nm, DLP UV curing light source spectral energy concentration. In recent years, UV LED curing light source chip technology has made great progress, at present, the main wavelength of UV curing light source chip 365nm above 40%, the luminous efficiency can reach more than. Mercury lamp light though the total radiation efficiency is high, but because of its spectral composition is very complex, covering the UV to the visible region, so effective ultraviolet radiation efficiency is relatively low. Therefore, as long as the radiation center of UV-LED meets the matching of the response wavelength of the coating, the radiation use efficiency of DLP UV curing light source is higher.

UV LED curing light source structure is compact, the unit area of the radiation power (that is, the power density). In the process of rapid solidification of floor coatings, the curing reaction has higher power density of UV radiation, and the power of UV curing light source is higher than that of kilowatt. The DLP UV curing light source has the advantages of small volume, compact structure, lamps and lanterns made of integrated chip package can realize high power density, strong irradiance can be obtained, and the whole system device can make relatively lightweight and convenient, convenient operation.

UV LED curing light source single side out light, high efficiency of the system. In high pressure mercury lamp, a gas discharge light source is to the whole space ultraviolet light emission, so in the practical application in order to improve the efficiency, UV curing light curing reaction systems are usually equipped with reflector, luminaire efficiency is only about 60%, resulting in a large radiation loss. And DLP UV curing light source is half space out of the light, the direction of the UV radiation is better, the efficiency of lamps can be up to 90%.

UV LED curing light source service life is long, can be open or close. Long life is one of the main advantages of UV curing light source. The traditional gas discharge lamp life is generally only 1000 to 4000H, and DLP UV curing light source service life can reach 20000 ~ 30000h. In addition, mercury lamps and other gas discharge light source started slowly, light from the start to stable need half an hour to one hour, and life is influenced by electrode, frequent switch lights will seriously influence the electrode performance greatly shorten the lamp life, so these lamps in use process must continue to ignite and large energy consumption. And DLP UV curing source of life and the switch frequency no significant correlation, and can realize the startup transient, so can only in ultraviolet radiation lighting, and the actual service life of the far more than gas discharge lamp life. In addition, UV LED curing light source such as the characteristics of the open and close can also avoid unnecessary power consumption, more in line with the requirements of energy saving and environmental protection.
