Does your project consider using LED

In April 25, 2009, the domestic authoritative experts, held in Shenzhen "seminar" and the trend of LED application products hot behind the rational call --2009, LED lighting enterprises, designers and terminal owners share a high level of wisdom. The seminar was warmly discussed.

Zhao Haitian, Professor of the Department of architecture, Shenzhen University: in the process of building design, do you have the lighting designer to suggest that you use LED products?

Zhao teacher: Thank you, you mention this issue is very wide and very deep, widely said from now lighting applications including landscape lighting, display lighting, lighting instructions and so on, and there is a large range of functional lighting, it is widely. From the deep, and now from the LED into the so-called alternative to the traditional light source, it is necessary to take into account the basic characteristics of LED, we found that in the teaching and scientific research, LED has several major characteristics: one is in the application of LED shape variability, because it is the basic form, we know this point an ordered arrangement can be turned into a line, then you can also become the permutation matrix, at the same time it has a folding, folding is of course conditions. This point can become the shape you imagine, it breaks through the traditional lamp or line, or is the point of light. From this point of view, it has a very strong plasticity. LED security, security is reflected in where we know that the safety of the human body is determined by two levels of voltage. One is the safety is not dry, wet conditions is 48 volts, so our phone line is 47 volts. Another is the presence of water, such as in swimming, including when bathing in the bathroom, the safety is 12 volts, so we in the electrical design specification provides a place with water is 12 volts, all mentioned LED is 24 volts, design specification requirements of swimming is 12 volts, the future can not be turned into 24 volts for LED? In fact standard is the electrical specification, it is not going to change, because the safety voltage of 12 volts of the human body, so it won't turn to 24 volts, never, this is a problem.

LED we say it's safe in dry conditions, because our power supply is 24 volts, some as a single particle is a power supply of 1.5 volts or 3 volts, it is safer. LED is a very important feature is its security, one is plasticity, the two is security. Third features we should attach importance to it is the fever, can be said that most of the energy in heating or, in this case, it is how a fever? It is not a little fever, but it is arranged in a matrix, it is always a hot point. A little of LED we know the cask effect a little hot, we from the mechanical point of view, it is the first point of collapse, when we design the LED application we can not take into account this point. From my experience in the design, we feel that the current from the LED products, downstream products and applications, we currently lack of application designed specifically for the characteristics of LED, including lighting products, including product application. Now many are still in the stage of replacement, or the lamp type, I think the real application of the best LED you may have not it light or what, at least not the traditional lamp type, traditional lamp type is extremely unfavorable for the heat dissipation of the LED. The traditional lamp type has a cover, this cover should be said to be a focal point, although can not focus on a point, but always focus on. I saw a lot of LED street now, some design mold design of aluminum cover, some is the tongue the traditional street lamps to light on the surface and inside of a change into LED, we say that no matter how light, from a design perspective is extremely unreasonable.

From the angle of application, LED future design from the environmental point of view, from the environment, let LED play a role not only to illuminate the role, but to create the environment, from this perspective, we may still have a long way, one is that we must study 460 plus stimulated yellow light and yellow phosphor light, he on human health and comfort of people affected. Two is the control of our technology, we want to create a suitable environment, control should not be a simple light control technology, even we have to consider some of the necessary sensor technology, remote control technology, if these technologies have been developed, I believe LED really play the other light source is unable to substitute their own special circumstances I think I'm afraid, is a revolution in lighting can be achieved.
