LED Tri-proof Light technology has made great progress, the energy is highly efficient and durable, which will bring about a thorough reform. In addition, the LED chip is very small, can be embedded in a very small space, its application range is wider than the previous radical light source, and its color rendering index is also becoming an ideal. The great success of LED technology has brought the possibility of the lighting industry, especially in the field of lighting design. Personalized lighting design, can better reflect the designer's intention, while the ability to complete the functional lighting. LED is growing at the same time, many scientific research units and chip manufacturers also OLED technology as an important direction of development. OLED products can be made smaller, can be applied to more places, the future development of more space.
