Rational lighting supports emotional "enlightenment"

“Rational lighting is the result of rational lighting design that can be achieved. Based on a comprehensive understanding of lighting objects, according to the laws of light, we can consider design requirements from multiple aspects, and be able to predict the lighting effect, so that it is not impulsive. Lighting design based on feelings.” Dr. Li Nong, director of the Urban Lighting Planning and Design Institute of Beijing Polytechnic University, said at the 2012 China Advanced Lighting Designer Forum held on December 20. He believes that rational lighting design is the precondition for producing rational lighting effects, and rational lighting is actually equal to scientific lighting.

Rational illumination design dialectics

Design creative design, technical design. Technological design requires rationality and science, and creative design has its own particularities and needs perceptual and intuition. But these two designs are mutually supportive, and the lighting design is the same. “Rational lighting is a perceptual “stomach” under the support of rationality. Epiphany is essentially the inspiration of creativity. Without creativity, there is no good idea, so this idea must be under the support of rationality, otherwise it is only castle in the air.” Dr. Nong said that the perfect combination of the two will ultimately create a beautiful and rational lighting pattern. Where is the dialectic? At the same time, there is a need for rationality. For lighting design, it is inseparable from the emotional component.

Rational lighting design basic conditions

For the basic conditions for rational lighting design, Li Nong summed up three points: first, having a design sense; secondly, understanding design methods; and third, mastering lighting technology. “These three basic conditions are fully representative of your potential to become an excellent lighting designer. Only the second and third can be an independent lighting designer, and suitable for functional lighting design, of course, the lack of The sense of design, but only the first and second conditions, can become a non-independent lighting designer, this type of person is suitable for landscape lighting design, can find some people in the company, he plans, other People cooperate with you to complete the final lighting design." Li Nong believes that such people can not be independent lighting designers, to find a team or a person with whom it is possible.

Rational lighting is synonymous with scientific lighting. If we want to create a rational lighting pattern, we must be able to cooperate with the right and left hemispheres, just as we need to balance and harmonize humans. Why can't we have left and right brains? He explained that because people's right and left hemispheres have division of labor, half of them have to think about images, and half of them need to engage in abstract thinking. Therefore, the left and right brains work well together. All three conditions are met. Only half is used. Heads can only do half of the work. Why is it like God shaping humanity? God's shaping of human beings is to balance. Eyes must be left or right, hands should be left or right, and lacking one should be unnatural. So the lighting design is the same, it needs balance and harmony, and finally we can find a rational lighting equipment.

Rational lighting and energy-saving control narrow sense energy-saving control

Energy saving and control are not difficult to understand. Narrow control is the use of lighting hardware to save energy. This hardware includes lighting related control equipment and lighting fixtures. Just like the lighting of Olympic venues is controlled by a set of control devices, it can achieve energy saving through its open time control and open quantity control. This is a narrow sense of energy conservation, that is, hardware to achieve energy savings.

Generalized energy saving control

Li Nong talked about how to use "software" to achieve energy conservation. For example, he can use energy planning and design to achieve energy conservation. From a design perspective, lighting a mountain in the same way can have a variety of different lighting methods. Different methods must have relatively more lights and fewer lights. This is all energy saving at the design level. .

Finally, Li Nong concluded that rational lighting is a prerequisite for energy conservation, but its connotation will be extended to a wider range of areas of design and design.
