On April 25th, 2009, Aladdin Lighting Network invited domestic authoritative experts to hold a rational call for the 2009 LED application product achievements and trends behind Shenzhen, to share high-level with LED lighting companies, designers and terminal owners. The wisdom of the results. The seminar was a lively discussion.
Aladdin Lighting Network Liu Jun Consulting Professor of Architecture, Shenzhen University Zhao Haitian: In the process of your architectural design, is there a lighting designer who actively recommends you to use LED products?
Teacher Zhao (Zhao Haitian Aladdin Lighting Network Blog >> ):
Thank you, this question is very broad and at the same time very deep. It is said that the wide range of applications from current lighting include landscape lighting, display lighting, indicator lighting, etc., as well as a large range of functional lighting, which is extensive. . In-depth, now from LED has been in-depth to replace the traditional light source, it is necessary to take into account the basic characteristics of LED, we found in teaching and research, LED has several main features in application: First, LED shape Variability, because its basic form is a point, we know that the orderly arrangement of this point can be turned into a line, and then can be arranged into a matrix of faces, and it has a certain foldability, of course, the folding is conditional. . This point can become the shape you imagined, and it breaks through the traditional luminaires either from the line or from the point of illuminating. From this perspective, it has very strong plasticity. LED security, where is the security? We know that the safety of the human body is determined by two levels of voltage. One is dry safety, that is, 48 ​​volts without water, so our telephone line is 47 volts. Another one is when there is water, for example, when swimming, including when bathing in the bathroom, the safety is 12 volts, so we have specified that there should be 12 volts in the electrical design code. All the LEDs just mentioned are 24 volts, the design specification for swimming requirements is 12 volts, the LEDs are safe in dry conditions, all are 24 volts, and some as a single granule is 1.5 volts or 3 volts, which is safer. . A very important feature of LED is its safety, one is plasticity and the other is safety. The third characteristic we can't ignore is its fever. It should be said that most of its energy is still in heat. How is its fever formed? It does not have a big fever, but it is arranged in a matrix. The fever is hit, and it always has one of the hottest points. The barrel effect, from a mechanical point of view, is the first point of collapse. We must not consider this when designing LED applications. From my design experience, from the LED products, downstream products and application products, we currently lack the application design specifically for LED characteristics, including lighting products, including product applications. Now many places are still in the replacement stage, or the appearance of this kind of lamp, I think the best application of real LED may not be able to distinguish it from the lamp or what, at least not the traditional lamp type, the traditional lamp type for LED Heat dissipation is extremely disadvantageous. Traditional lamp types have a cover, and many covers should be said to be a focal point. Although they cannot be focused on one point, they are always in focus. I now see a lot of LED street lights, some of which are better than the aluminum cover of the mold design. Some of them are the traditional snake-head street lights that change the light source inside and turn into LEDs. We say no matter how the light shines, from design The point of view is extremely unreasonable.
From the application point of view, the future design of LED from the perspective of the environment, from the requirements of the environment, let the role of LED not only to illuminate, but to create the role of the environment, from this perspective, maybe our way It is still very long. One of them is to study the light that is stimulated by 460 nm plus yellow and yellow phosphors, his influence on human health and human comfort. The second is our control technology. We want to create a suitable environment for people. Control should not be a simple control technology for lights. We must even consider that we have some necessary sensor technology and remote control technology. If these technologies are developed, I believe LEDs. When other light sources that really exert their own traits are irreplaceable, I feel that the revolution of lighting is realized.
