Weekly LED new products come out, but if LED products want to maintain their dominant position in the next few years, their costs must be reduced to some extent.
The US Department of Energy (DOE) developed a solid-state lighting production target last year that will reduce production costs by a factor of 10 by 2020, which is far from enough. The LED industry currently has to compete with fluorescent lamps and must spend every thousand in 2015. The cost of lumens has dropped to the current 1/8. According to previous data, the current $18 per 1,000 lumens will be reduced to $2.20 per lumen. DOE will release its LED final solution this summer.
According to a survey of industry experts, the best practices for reducing costs are as follows: system integration, measurement testing, and fluorescent materials. At the same time, special equipment for the production of LEDs also brings a way out for reducing costs.
DOE Research Funds develops low-cost projection lithography tools by introducing Ultratech specific design processing of curved transparent sapphire substrate tools; introduction of inspection tools designed by KLA-Tencor to map micro-wells that cause LED defects; introduction of Sandia National Labs And Veeco's pyrometer; this pyrometer can directly measure the critical temperature of transparent wafers, which can better control the quality of epitaxial deposition.
Users and suppliers are constantly striving to move toward standards for the SEMI Standards Committee, including standards for the production of sapphire substrates and hardware and software interfaces for industry-related system automation.
The progress made in reducing unit lumens costs Paul Scheidt, product sales manager at Cree, pointed out that the recent progress in producing LEDs means that our LED bulb prices are closer to $10. The key is that significant progress has been made in the effective display area, which has continuously reduced the cost of LED lighting and heat dissipation. He pointed out that this advancement has reduced the cost of LED packages and chips and ensured the consistency of color; this packaging mode is easier for users to use directly. The metal matrix LED chip allows non-reflow soldering equipment users to connect the heat sink substrate by hand soldering.
Combine each blue chip with the correct fluorescent material to get continuous white light. The 100 lm/W chip completed in the laboratory will be ready for volume production. Scheidt pointed out that "the highest efficiency that can be achieved in the laboratory is 230 lm/W; while the efficiency of current industrial products is 130 to 140 lm/W. Future development will depend on fewer LEDs."
He pointed out that regulators have evacuated the market from products that are not functioning; large-scale malls have also emerged with low-cost light bulbs. He pointed out, "The quality of these bulbs is much better than anyone expected a year ago. The consumer market will grow much faster than expected. With the development of the market and the emergence of new products, the cost will no longer seem so important. We may be able to draw some conclusions from the development trend of thin-film LED TVs."
Simplifying the assembly of a small number of components of the system has also made progress in simplifying the design of LED systems. One of the suggestions for simplifying the system is Intermatix's Remote Phosphor technology. Chuck Edwards, vice president of Intematix, points out, “We have seen more of the efficiency of integrated design; in the near future, we will provide a variety of efficient materials and a better thermal management system.â€
The advent of Remote Phosphor technology has made the integration of fluorescent materials and chips easier; and it has also lowered the temperature and improved its performance by removing the fluorescent material on the chip. Using the Remote Phosphor technology also simplifies the packaging problem and provides more freedom for using the COB package. Edwards pointed out that "many general lighting solutions will point to the COB package."
Advances in Quantum Dot Technology's advancements in Quantum Dots have also improved the efficacy of LEDs; this potential application has facilitated the large-scale production of such nanoparticles and provided practical solutions for layers of polymer latex for lighting applications. . These nanoparticles can emit the ideal color, which is lower than the luminous efficiency of the fluorescent material. Suresh Sunderrajan, president of NNCrystal, pointed out that “in order to simulate natural light, the luminous efficacy of fluorescent materials should reach 50-60%â€.
Both Acuity Lighting and other suppliers' lighting secondary optics use NN Crystal's quantum dot solution to generate warm white light. Sunderrajan pointed out that NNCrystal's technology can reduce the loss of resorption by distinguishing between the emission and absorption characteristics of the core and shell regions; it reduces the absorption and thus increases its efficiency. The company has developed a stable and uniform polymer dispersion and 3D precision coating process. And it has begun production of this quantum dot material in its Chinese factory.
Smart Lighting Increases Value As technology advances, users find that semiconductor lamps have more uses than lighting. Combining the LED with some simple sensors and controllers can deliver the required light at the right time and in the right place, thus improving the energy utilization. Jeremy Steiglitz, vice president of architectural solutions at Redwood Systems, pointed out that using LED and low-voltage DC network sensors to replace the traditional fluorescent Re-lighting program, users will recover investment profits within two years.
"Lamps are like trojan horses everywhere." Once the network is installed, users will find other uses. Another wonderful application was found in the management of conference rooms. Occupancy sensors can detect which rooms are in use, as well as the number of people in the meeting; this makes it easier for users to find meeting rooms; managers can also quickly determine how large a company’s employees need to be.
