Optical Design

The luminescence characteristics of rare earth ions mainly depend on the characteristics of the 4f shell electrons of rare earth ions. With the change of the number of electrons in the 4f shell, rare earth ions usually exhibit different forms of electronic transitions and very abundant energy level transitions. Therefore, rare earth ions can absorb or emit light of various wavelengths from ultraviolet to infrared, forming various luminescent materials which can be widely used in many fields, such as energy-saving lamps, semiconductor lighting, flat panel displays, and blinking crystals. The excellent luminescence properties of rare earth ions have laid the foundation for the manufacture of high-efficiency luminescent materials. Rare earth luminescent materials have the advantages of narrow emission band, high color purity, bright color, strong light absorption, high conversion efficiency, wide emission wavelength distribution range, fluorescence lifetime from nanoseconds to milliseconds, reaching 6 orders of magnitude, making rare earth compounds a highly explored et al.

Why need optical design?

In general, the light sources are composite light in life, which has low purity, may greatly restrict its application. A purer light source may have a more comfortable experience and a more precise direction of use. For high-purity or special light sources, it can be used in specific occasions, such as white light-emitting diodes, fluorescent devices, and scientific research. Therefore, we need to adjust light to achieve.

The advantages of white LED

  • Brightness and light color are adjustable to meet the needs of various occasions
  • It can carry out dynamic control and provide reasonable solutions according to requirements
  • Long life, no mercury
  • More energy saving and environmental protection
  • Directional radiation within the beam angle, which is beneficial to improve the downlight flux ratio
