The new angle of view: rational illumination is the emotional enlightenment"

"Rational lighting is by reason of lighting design in order to achieve results, based on a comprehensive understanding of lighting objects, in accordance with the law of light, to consider the design demand from many aspects, and can predict the lighting effect, do not impulse, not feelings do lighting design. Dr. Li Nong, director of the Institute of urban lighting planning and design, Beijing University of Technology, said in December 20th, "2012 China advanced lighting designer forum". He believes that rational lighting design is the premise of the rational lighting effect, rational lighting is actually equivalent to scientific lighting.

Dialectics of rational lighting design

Creative design and technical design. Technical design is rational and scientific, and creative design has its own particularity. But the two designs are mutually supportive and the lighting design is the same. "Rational lighting is rational under the support of sensibility", "epiphany Epiphany is essentially a creative spark, no flash no good ideas, so the idea must be rational support, or just castles in the air. Dr. Li Nong said, "the perfect combination of both to create the final form colorful rational lighting. Dialectical in what place, the need for rational at the same time, for the lighting design is inseparable from the emotional component.

Two, the basic conditions of rational lighting design

To do a good job of rational lighting design of the basic conditions, Li Nong summed up three points:

First, with a sense of design.

Second, understand the design method.

Third, master lighting technology.

"These three basic conditions are all in your hands and you have the potential to be a good lighting designer. Only second and third can become an independent lighting designer, and suitable for functional lighting design, of course, the lack of design sense. Only grasp the first and the 22 conditions, can become an independent lighting designer, this kind of person is suitable to engage in landscape lighting design, you can find some people in the company with him out of the program, other people to cooperate with you to complete the final lighting design. "Li Nong believes that such a person can not become an independent lighting designer, looking for a team or a team of people can be.

Rational lighting is synonymous with scientific lighting, in order to create a rational form of lighting, inseparable from the left and right sides of the brain, just like the need to create a human balance and harmony. Why not open from left and right hemispheres? He explained, because the left and right sides of the brain is a division of labor, half is to make the image thinking, half is to abstract thinking, so the brain with the good, three conditions are met, only half a head only half dry what. Why is it like God created human beings? God created human beings should be balanced, the eyes should be left to right, hand to left, right, one is not natural. So lighting design is the same, the need for balance, harmony, and finally to find a rational lighting equipment.

Three, rational lighting and energy saving control

Narrow energy saving control

Energy saving, control is not difficult to understand, the narrow sense of control is the use of lighting hardware to achieve energy saving. The hardware includes lighting control equipment and lighting fixtures. Just like the lighting of the Olympic Stadium, it is controlled by a set of control equipment, which can be realized through the control of the time and the quantity control. This belongs to the narrow sense of energy, that is, hardware to achieve energy saving.

Generalized energy saving control

Li Nong talked about how to use the software to achieve energy saving, for example, can use lighting planning, design and other ways to achieve energy saving. From the design perspective, the same lighting a mountain, lighting can have all kinds of different ways, different methods have relatively light and light much less difference, it is energy saving can be achieved in the design level.

Finally, Li Nong concluded that rational lighting is the premise to achieve energy saving, but its content will be extended to a broader scope and design.
