Here in this article, we will continue the interview of Professor Holland Yake from the University of Illinois, who is an expert of laser and light emitting diode (LED Panel Light ). The topic of today’s interview is the future of LED lighting technology.
Is there anything we can do to improve the LED lighting technology?
There are a lot of things that we can do to make them more competent to be the best and brightest lighting source in the world. Currently, we are looking for better wafers, committing crystal chemical researches, etc.. I made an alloy in GE. Then I made other semiconductor alloys, they are getting better. They can emit red-orange light, and also yellow light. Some other people who were doing similar works tried to use other types of alloys, which are able to send out blue rays. But when they tried to convert these blue rays into green, they met with big problems. No one presently can solve this problem very well and obtain yellow rays.
After these years development, has LED been the mainstream lighting source?
Basically, LED is beginning to take over the lighting market, from special lighting to ordinary lighting. For now, the whole world is using this technology, in various forms and various colors.
Is it possible for us to see the continuous growth of LED lighting technology?
You can treat them as a kind of lighting source, but also can use them as laser, just like in the field of surgery and photosensitizing. This is the biggest feature of LED, since incandescent bulbs cannot do these staffs. You can use LED to make a lot of things, both in the medical area, the instrumental area the automobile area. All lights used on vehicles can be replaced by LED lights. As a matter of fact, LED lamps are more advanced in automobile applications due to their small sized and flexibility in forms and designs. LED headlights and taillights are more durable compared with traditional high-pressure sodium lamps. This is not the end of the story. To be honest, LED is in her infancy. It seems that LED has already stepped into her adolescence, but trust me, she needs more time to grow up. The only thing we can do now is just wait.
