Light whether to love?

LED light source has been widely known, with the emergence of white LED, as well as the continuous improvement of light efficiency, no one doubts the future development prospects of LED. In the history of the development of lighting technology, the development of LED is only a few decades, but now the LED also from the early 70s as an indicator of the instrument developed into a highly efficient lighting source. According to reports, the light effect lighting the new world record was created by LED, the level of industrialization of LED light efficiency has reached 100lm/W, the laboratory has reached a level close to 160 lm/W, the LED luminous efficiency is expected to reach or exceed 200 lm/W. Therefore, LED into the general lighting is expected, but it should be noted that there are still some problems need to face up to LED and strive to improve. On the contrary, the traditional lighting source is widely used in many fields because of the advantages of color and cost. Therefore, in reality, the use of incandescent lamp, fluorescent lamp, the traditional light source or a new solid-state light source with LED? Is a high power LED or small power LED? This has long been a problem in the lighting industry.

Summary of parties opinions, summed up can be divided into three categories, namely the earliest Lianjiu faction, radical and rational new hi hi new Lianjiu pie.

As the name suggests, is to support the traditional light source Lianjiu pie. I would like to engage in lighting many people have had this idea in the early days, but with the progress of LED technology and highlight the advantages of those who hold such views are mostly with the times. Recently, I participated in the seminar held in Tianjin, the two sides of the Strait lighting technology and marketing, the meeting was jointly sponsored by the China Institute of lighting and the lighting industry in Taiwan region. According to the usual view, the two organizations would be well advised to the same, are supporters of the traditional lighting firm, experts are invited from the traditional lighting field, but the theme of the conference is "LED and traditional lighting", the topic of discussion is about the LED. This lighting circles have to open mind progress embraced LED later this intruder.

But the new question is also followed, that is, whether the LED completely replace the traditional light source? Dr. Li Liling in the cross strait lighting technology and marketing seminar from Taiwan ITRI has put forward such a problem: the lighting source selection, whether you love?

We can see LED in the landscape, instructions, display, backlight, lighting and other special applications have played a great advantage of energy saving, longevity, fast response and so on. In addition, the brightness and color of the dynamic control is easy, the size of the small size, long life, the beam does not contain infrared and ultraviolet light, a strong direction of light and other characteristics of the advantages of large-scale LED into the field of general lighting. But is it not to think that LED must replace other sources? I think that as long as a rational thinker, certainly not simply think that as long as the latest is the best. At present, LED still has some limitations, such as cost, light color quality, reliability, heat treatment and so on. Similarly, high power LED power LED is small compared to the bright younger generation, are widely optimistic about the prospects, so small power LED whether to end? I don't think the rational answer is absolute.

As some wise men say, there is nothing that is really useless, and some are misplaced resources. In the choice of lighting source, there is no really useless light source, and some are just wrong or improper use of light. Looking at the use of lighting in a variety of light sources, very primitive candles, still in some special occasions with a warm light. The fact that the existing light source is not absolute good and absolute is not good, as long as the right place to make good use of, have its value of existence. But in the continuous development of science and technology, the popularization and application of new light source will also is the social development of science and technology, so treat source selection problems, I think the best answer is "love the new and nostalgia", in the mind all rivers run into sea and make full use of advantages of different light sources, at the same time to get rid of the development and application of energy-saving light source model and fearless the.
