LED has advantages and potential, but has not yet become the main force in the field of lighting

Asked: recently the media of lighting LED lighting technology products, many reports have even said "high brightness LED will be human after Edison invented the incandescent light bulb, one of the greatest inventions." As a well-known expert in the field of lighting, do you think LED is the best lighting appliance in the future? What are their views on the future development? A: enter the field of LED lighting it is the progress of science and technology and human. It has many advantages and great potential, but still failed to become the main force in the lighting field, still have the research, development and improvement. Now we give attention and encouragement and sufficient financial resources, effort is very necessary and have good LED progress, but too overstating or easily dubbed "the most" rating, this is the age of our Chinese is difficult to accept, in accordance with the past received experience, my idea is many small talk may be more pragmatic and effective. Q: I read about LED product information recently, the products are mainly used in automotive lighting and outdoor lighting, and no indoor lighting. Do you think it is difficult for LED to be used for indoor lighting?

A: LED in the decoration, landscape, signal, red and green traffic lights, garden lights, car parts and some special purpose lighting lamp has been widely accepted, but it's cooling, optical design, single frequency output power and luminous flux and the price is just passable, of course the light effect also needs to be further improved. At present, with white LED light effect in 50-60lm/W commercial, 1W white LED price of about 30 yuan, the need to improve and improve the utilization of indoor lighting can be more. Asked: in addition to the use of energy saving low energy consumption products, the use of renewable energy is also an effective means, recently SHARP and other companies have launched solar LED lighting products, which can be regarded as a direction for the development of LED? A: LED and combined with the use of solar and wind power, due to LED's low voltage driving characteristics, it is more advantages, but also the human existing traditional energy: such as oil, coal, natural gas, nuclear energy and so within 200 years to dry up, thus promoting renewable energy such as solar and wind energy is effective, the development of LED lighting in this direction is an inevitable trend, but also have a considerable advantage. Asked: the southern coastal city of Chinese volatile weather, rainy season when the sunlight is not sufficient, and the wind is not large, these factors will affect the solar energy, promote the use of wind energy? Answer: these problems, from the technology can solve the sun the lack of sunshine, wind energy is limited, can even take ordinary power supply and renewable energy complementary strategies. Now the problem is that the utilization efficiency of solar energy and wind energy is not high and the cost is very expensive. In this respect, it is necessary to make a greater contribution to the science and technology personnel. Asked: you not only engaged in research of optical power supply the doctor is the mentor, the electric light source in the personnel training can you talk about some personal ideas? As a teacher I want to work, now is the rapid development of information era, innovation is the soul of the development of the industry, independent intellectual property rights is the real source of corporate profits, and it all depends on the talents, training talents of our country from the electric light source is an important and fundamental measure of electric light source manufacturing superpower to power, "ten years to grow trees, a rare, more able to care for a person with breadth of vision of education, we would like to Xin our students can study hard, accumulate steadily, truly become the country a man of tremendous promise. This is also the time given to us to do an important duty of the divine teacher.
