This time, I selected two places for lighting analysis. The first one is the lobby next to the entrance, as the lighting there is a combination of natural light and artificial light.Another place is an exhibition hall because I want to incorporate the museum’s display style into my store design.

The painting of the hall helped me understand the role of shape and materials in lighting. The shape of the interior can affect the propagation of light, such as curved roofs that facilitate the reflection of light. Materials also have an impact on light, with rough stone roofs conducive to diffuse reflection of light, and smooth stone brick floors conducive to refraction of light.

The paintings in this exhibition hall have taught me about the impact of object colors on light and key lighting examples.

The color of an object not only affects its brightness, but also the amount of reflected light. Under the same lighting intensity, a light colored roof will reflect more light than a dark colored wall. Or rather, because light colors can reflect more wavelengths of light, they appear lighter.

This exhibition hall mainly uses track lights as light sources, as these lights facilitate adjustment of orientation and brightness, which can better meet the special needs of exhibits. At the same time, this exhibition hall also features some illuminated booths to highlight items, such as some old wooden storage boxes.

This blog will discuss the first theory “First, do no harm” “Our eyes were built to use light… not to look at light!” “Visual effects of light can be physical”

With the progress of interdisciplinary research, it has been found that light has an impact on human physiological activities. Harmless lighting design should not only focus on not causing irritation to glasses. As designers, we also need to consider the physiological and psychological connections between lighting and metabolism, brain activity, emotional resonance, etc.

But as I read more articles, I found that discussing whether lighting design is suitable is more reasonable than discussing whether it is harmful. We cannot directly equate harmless lighting design with Human Centric Lighting（HCL） design.

I saw an example. The human physiological system, rather than the visual part, has the optimal light dose. Office workers are exposed to 3000K or 3500K fluorescent or LED lights all day long. These workers do not receive much sunlight and do not have sufficient rest outdoors during the day. Even fixed 5000K LED lighting can better improve short-term and long-term alertness.

I feel that the case above is too rational and somewhat inhumane. But there is actually a connection between lighting design and morality.John Bullock pointed out that when designing advertising signs, we should not only consider how bright it is to achieve the best promotional effect, but also consider how to reduce the impact of advertising lighting on people. For some designs, it is not lighting or advertising that deceives people, but the people who design the advertisements. It‘s people who are deceiving people.

Actually, I think Edinburgh’s urban design is quite good, not letting consumerism drown out traditional culture.
