LED Emergency Lighting Technology Application


With the sustained and rapid growth of China's economy, energy consumption continues to increase, and the contradiction of energy shortages has become increasingly prominent. "Research and development of high-efficiency, energy-saving, long-life semiconductor lighting products" is included in the national medium- and long-term science and technology development plan (2006-2020) "energy" field "industrial energy saving" priority theme, the development of China's semiconductor lighting industry is welcoming from the main A major historical opportunity for innovation and leapfrog development.

First, the importance of led emergency lighting applications

Emergency lighting is an important safety facility for modern public buildings and industrial buildings. It is closely related to personal safety and building safety. When a building has a fire or other disaster, and the power supply is interrupted, emergency lighting has an important role in personnel evacuation, fire rescue work, and the continued operation or necessary operation and disposal of important production and work. Through the research and development and application of LED lighting application products, it can change the current situation that China's current daily lighting and emergency lighting integration products are scarce, and can not guarantee the production and living requirements in an emergency; combined with the implementation of national energy conservation and emission reduction targets, a series of civilian applications should be developed. Emergency semiconductor lighting products, in addition to meeting energy-saving requirements in daily use, provide sufficient illumination and lighting time in emergency situations to escape, rescue property and repair power systems. Develop lighting products with built-in power generation function in special emergency environment, which is easy to carry and use, can be recycled many times, and has its own protection function.

In the event of natural disasters such as fires and earthquakes, emergency lighting is an essential equipment for escape and disaster relief. It is expected that the market demand for semiconductor lighting series applications with emergencyfunctions will exceed 2 billion yuan in the next three years. With the development of China's economy, the safety awareness and safety standards of the society have been greatly improved, and the requirements for emergency lighting products are also getting higher and higher. This not only requires such products to meet emergency needs, but also has the performance of energy saving, humanization, high reliability, and the biggest advantage of emergency semiconductor lighting is here. At the same time, with the development of China's economy and society, the demand for lighting in disaster relief, field construction and off-grid and harsh environments is increasing, and there is also a huge market demand for emergency semiconductor lighting products.

The goal of the "Emergency Lighting Efficient Drive Technology and System Reliability Research" project is to promote development by application, break through the key industrial technologies urgently needed for LED lighting applications, and improve the semiconductor lighting industry chain.
