In today's world, smart lighting and smart cities are often in the spotlight. Indeed, in recent years, driven by next-generation information technologies such as the Internet of Things, cloud computing, mobile internet, and big data, smart lighting has been rapidly evolving. However, during this development process, are there any areas that have been overlooked?

Professor Xiao Hongqing raised this question at the 2017 Semiconductor Lighting Industry Conference. He aimed to explore and appreciate the quality of lighting engineering through the lens of Chinese ethics and Zen wisdom.

● Complexity Is Not Always Better – Lighting Should Be Appropriate

"Our engineering design and lighting planning are not easy to miss, which is a key focus for the 2018 LED supply and demand market," said Professor Xiao Hongqing.

It was concluded that the LED output value in 2017 reached $17.16 billion. For the general lighting market, there is about 60-70 billion potential replacement lighting fixtures worldwide. It is estimated that around 6-7 billion LED lamps will be used annually by 2020. Therefore, it will take about 10 years to reach saturation, and the LED lighting market is still promising.

On the other hand, the night travel economy drives the construction and landscape lighting market. China’s 300 prefecture-level cities and 2,800 county-level cities combine dynamic lighting control technology with LED curtain wall lighting and music shows to create cultural cities along rivers, coasts, lakeshores, and city squares. If 5% of cities promote their lighting projects each year, it can form a multi-billion-dollar demand in the landscape lighting market.

The Taoist sage Laozi once said, “The Dao is natural.” In places like Japan and Rome, some lights are designed to evoke the feeling of moonlight (Figure 2). What is the sensation under ancient moonlight? Lighting should reflect that feeling, because of nature.

Comfortable vision should not be excessive, too bright, or overly intense. While not impossible, it may not always be ideal. For example, the four towers in Figure 3 appear very comfortable at first glance, without being transitional or over-packaged. This is a natural taste. The three towers in Kyoto, Japan, Beijing, China, and Kuala Lumpur, Malaysia, create a simple and beautiful color effect; Guangzhou's small waist presents a modern color banquet, full of dynamism but not dazzling, each with its own unique character.

Night landscape lighting should emphasize natural characteristics rather than blindly pursuing brightness. The four items in Figure 4 use color changes to create different effects, but over-emphasizing color changes can lead to ignoring natural qualities. Excessive beauty might lose the elegance and calmness of ancient towns, which may not be a clever design. If landscape lighting is too bright, it can overshadow the simplicity of villages, often leading to monuments and disasters.

Urban landscape lighting seems to have forgotten the basic requirements and functions of nighttime lighting. Street lights and street lighting are typical examples. These projects may actually be urban disasters rather than brilliance! The light is too bright, the colors are distorted; placing lights on trees to project the depth of leaves not only makes the lighting uncomfortable and unnatural but also becomes the “urban animal killer,” affecting birds’ rest. Sometimes over-emphasizing “people-oriented” design reflects human selfishness, ignoring the fact that the global village includes humans, animals, and plants, all sharing the earth’s resources.

The problem is evident, especially in residential area lighting. After dark, is it really necessary to maintain the same light environment as during the day? According to Professor Xiao Hongqing, residential area lighting is like a red-light district in a bar. The lighting control has been done, but humanity and nature have been lost.

In ancient times, it was emphasized that “the Dao is natural.” If discoloration control is separated from natural laws, it may be counter-intuitive. There is a connotation of intelligent control, but no true intelligence component.

Lighting design master Zhou Lian stated that historical lighting design should moderately reduce the brightness of the light. Dimming design may not be as good as glare lighting. We need to restore the true taste of cultural relics.

● The Characteristics and True Pursuit of Intelligent Lighting

In all wireless remote control design ideas, is there any important basic principle that has been ignored by designers?

It is convenient to use a mobile phone to control lighting, but it can cause eye strain if used for long periods. “For example, during student learning, forcing students to stand up, leave their desks, and turn off the lights is a healthier approach,” said Professor Xiao Hongqing. Controlling everything with a mobile phone is what everyone wants, but we have missed health and humanity.

Professor Xiao Hongqing mentioned that for most people, 70% of the existing functions of most electrical products and smartphones are redundant and not used because users, especially seniors, do not understand the instructions and explore themselves. Half a day, they also learned painfully. This is a design flaw, missing the convenience needs of humanization.

Smart lighting should pursue health, nature, and let all living things share the earth. Figure 8 shows that in this year’s Olympus photo contest, 150,000 photos were selected for the only special prize. Professor Xiao Hongqing likes this photo very much. It doesn’t have very beautiful clothes, no lights, no special bright colors, and no grand expanse, but it records the warmth of a family. The simple and natural smile is the natural color. He believes that light is actually like this.

● Human Factors Engineering and Intelligent Humanized Lighting

The purpose of lighting is to provide a high-quality and comfortable visual light environment. So, what kind of light environment meets the requirements?

Appropriate brightness, brightness, avoid glare, natural color rendering, regulate color temperature, reduce flicker, and optimize luminous efficiency.

Light pollution is an issue that extends glare, resulting in new norms of light pollution and photobiosafety. These conditions are the conditions of "And," not "OR" or "Conditional," and all of these conditions must be met.

Do dynamic lighting, especially to control the damage of the stroboscopic light to the eyes and physiological adverse reactions (triggering epilepsy and dizziness and vomiting).

Humans need to use light to create excitement for life. Lighting technology must be innovative, and enterprises can be competitive and future-oriented; but lighting should not be just lighting.

Smart lighting control should be different from smart lighting.

Intelligent control is the use of scientific methods, techniques, means strategies, combined with physical world resources, the development of hardware equipment systems, providing control technology that facilitates comfortable life, is the physical world level of the metaphysical.

And wisdom lighting is the experience of life, the essence of experience feedback, information analysis, rational induction, combined with humanized needs and habits, based on the purpose of safety and health, adding intelligent control technology to achieve a truly comfortable and healthy life, is Metaphysical healthy world.

“Lighting equipment + sensing components + capital equipment + control system software = smart lighting,” this answer is wrong! Professor Xiao Hongqing said very seriously. This definition and cognition is not wisdom in itself. It is a typical materialism, lacking humanity and the natural philosophy of necessity and necessity.

In the future, smart lighting in all major venues will have a focus on application.

Commercial lighting should be energy-saving, commercial promotion, situational creation, healthy and comfortable development;

Industrial lighting should have production monitoring, energy saving, and safety guidelines;

Public lighting should save energy, collect data, protect the environment, and maintain it safely;

Residential lighting should meet human factors, create context, be healthy and comfortable, and save energy.

“Why do students go to sleep in class? Because the light lacks color temperature control, the average person can only maintain about 40 minutes at the same color temperature, so we have to be truly intelligent lighting control for human health.”

Professor Xiao Hongqing believes that intelligent control + healthy human factors, including the human needs we can now see, can be truly intelligent lighting.

● Understanding Lighting from Zen Wisdom

Lost life is one of the biggest drawbacks. Millions of Dzi Beads are more aura, masters bless and light up to be effective, temples want big money to burn big incense and keep safe, otherwise Bodhisattva is not happy, these are stupid, lost, unable to produce wisdom.
