1. High cost performance. Under the condition of ensuring monochromaticity, the power can reach a higher level with more lower price than laser light source;
2. More wavelength selectivity. In the range of 250nm-1000nm, LED light source can be almost all band selectable, while the wavelength selectivity of the laser is very limited.
3. Strong environmental adaptability:LED light sources have significantly lower requirements for temperature, humidity and other environments than lasers. In addition, LED light sources is more smaller and can be highly integrated.
4. Long service life. The service life of LED light source is more longer.
5. Low maintenance cost.LED light source is easy to assemble and disassemble.
