Semiconductor lighting has huge potential - — Visit professor da-hua Chen, deputy secretary-general of China lighting academy

Reporter: recently for a period of time each lighting media reports on the LED lighting technology, product a lot, some people even said that 'high brightness LED will be after Edison invented the incandescent light bulb, one of the greatest invention. Well-known experts 'as the lighting area, what do you think the LED is the most ideal lighting source in the future? For its future development?

professor Chen: this is LED into the lighting area of science and technology progress

and the Gospel of mankind, it is has many advantages and great potential, has yet to be research, development and improvement. Now everybody attention and encouragement and sufficient financial resources, effort is necessary, at the progress of the LED, but too high or easily dubbed 'the most' rating, we this age Chinese is more difficult to accept, I think more than do less speak more practical and effective.

reporter: at present, the LED products are mainly used in automotive lighting and outdoor lighting, and no indoor lighting. What do you think in this respect?

professor Chen: LED in decoration, landscape, the signal, the red and green traffic lights, courtyard lamp, auto parts, lamp, and some special purpose lighting has been widely accepted, but its heat dissipation, optical design, single frequency power and output flux and cost-effective, also, of course, its photosynthetic efficiency also needs to be further improved. At present, the business was in the 50 - in white LED the luminous efficacy 60 lm/W, and 1 W white LED price about RMB 30 yuan, all of these need to be improved and can be used in indoor lighting.

reporter: energy saving products in addition to the use of low energy consumption, use of renewable energy is an efficient way of effective, recent sharp company launched solar LED lighting products, such as it can be seen as a direction of the development of the LED?

professor Chen: LED and solar energy, wind energy used in combination, due to the low voltage LED driver characteristics, its application advantages, but also human existing traditional energy sources such as oil, coal, natural gas, nuclear energy and so on are all within 200 years to dry up, thus promoting renewable energy sources such as solar and wind energy is effective, LED lighting development is the inevitable trend toward this aspect, but also have considerable advantages.

reporter: China's southern coastal city weather rain or shine, the rainy season it is not enough, and the wind is not big, these factors will affect the use of solar energy, wind energy promotion?

professor Chen: these problems, is the sun the sun can be solved from the technique, the problem such as wind power co. , LTD. , you can even take common power supply and renewable energy complementary strategy. Problem now or solar and wind energy use efficiency is not high and the cost of expensive actual problem, this problem has yet to be renewable energy science and technology personnel to greater efforts.

reporter: you are not only engaged in light source, and doctoral tutor, talent cultivation in electric light source please talk about your personal thoughts.

professor Chen: now is information developing era, innovation is the soul of industrial development, independent intellectual property rights is the true source of corporate profits, but it all depends on talents, cultivating talents is the electric light source from electric light source made the first big country to power an important and fundamental measures, 'ten years) tree, ents in one hundred', mothballed can more people concerned about education career, wish our students to study hard, whole, truly become a pillars just by the state. This is also our teacher sacred duty endowed era.
