According to relevant information, in the part of LED light source, with the rapid improvement of white LED luminous efficiency and rapid price reduction, white LED with color rendering index of 70-90 is increasingly applied in the field of architectural lighting.
There is also another challenge in the application of architectural lighting, that is, the adaptability of LED lamps to various complex outdoor environments (such as climate, water, dust, acid and alkali corrosion, etc.). For example, high-power LED in outdoor heat dissipation problems; Lightning often causes problems in building lighting fixtures; Lamps and lanterns in the rain, water protection performance and so on, these need to choose components in lamps and lanterns, design a time.
Related news, white light LED with low voltage, low power consumption, high reliability and long life and other advantages, is a green light source in line with environmental protection, energy saving, can be used for building flood lighting and decorative lights and other products. On the other hand, white LED technology still needs to be accumulated and mature, and it needs to tackle key problems in core, fluorescent body and package, improve chip quality and structure, optimize RGB light-regulating drive and mixed-light control circuit design, improve luminous efficiency and reduce color temperature deviation. However, in the LED plane light source, it is necessary to improve the reliability, and to overcome the common phenomenon such as spot spot and uneven color mixing.
