Discussion on the Sustainability of LED Lighting

With the fever of “global warming, energy saving and carbon reduction”, the LED lighting industry is regarded as one of the most immediate and effective solutions. All countries are fully committed to developing and implementing a large number of test plans. The huge market with trillions of dollars in the world has attracted many manufacturers and practitioners who are not lighting industry to jump into this exciting industry, develop a wide range of LED lamps, and try to save energy and reduce emissions. The sustainable development contributes to its own strength.

However, in the case of the industry is not yet mature, LED lighting failure cases abound for many years. There is a strange and uncertain atmosphere in the entire LED industry's practical application and development of lighting. Dachang, a traditional lighting brand, is looking forward and cautious when it comes to the LED lighting industry from the traditional lighting industry. It has not dared to make big strides in terms of product quality, reliability, and product sustainability.

Although LEDs have been claimed to be capable of reaching 100 lumens per watt, a closer look at the product specifications often focuses on the initial lumens. For a practical lighting fixture should maintain the lumen, effective life, illumination and distribution, and even the sustainable development of the LED industry, there is little in-depth exploration.

Some industry experts pointed out that "the most important but related to the fundamental problem of the entire industry chain is that as a manufacturer of LED lamps, it is possible to manufacture and provide consistent LED lamps on the current general LED lighting technology platform for a long period of time. Does the product meet the long-term application requirements of the lighting market? While the luminous efficiency of LED chips provided by LED chip suppliers continues to increase each year, the LED lighting industry essentially has a problem that restricts the healthy development of the entire industry. That is the sustainability of LED lighting."

According to the current technology development blueprint for LED chips and packaging suppliers, the initial luminous efficiency (lumens/watt) of LEDs will continue to improve over the next decade. "So, it can be foreseen that the LED lighting manufacturers using the current general LED lighting technology platform, in order to maintain the brightness and lighting effects of their lighting products can meet the consistency of the original design lighting effects, must be cyclical year by year This can be achieved by changing and redesigning its LED fixtures and internal components.”

Once the luminous efficiency and total light output of a single LED package change, the entire LED light module, secondary optical design, power supply, and drive circuit must be changed accordingly to match and adapt to the original lighting design lighting effect. Once any component that constitutes a fixture changes, the product will usually be re-certified by the market. The design of the updated version of the luminaire will also result in long-lived and reliable tests and verifications repeatedly requested by the market.

How to ensure the consistency of long-term supply of LED lighting products will become a key issue in the entire LED lighting industry supply chain. If the lighting industry does not establish a common product technology platform and fixed-size LED light sources, the timing of product launch and inventory preparation on various supply chains will be unpredictable and controllable; frequent product upgrades also do not meet the needs of continuous development. If you have to introduce new products year after year and cannot mass produce and continue to supply the market, this will be a dream for LED lighting manufacturers.

Therefore, to completely solve the problem, the lighting industry must have a sustainable LED standard light source and a universal technology platform that can meet the continuous development of LED lighting, and develop LED energy-saving lamps based on the sustainable lighting technology platform. LED maximum energy saving effect.
