Humans Factor In Lighting, which can also be called comfort lighting, refers to the adjustment of lighting to change people's work and rest. This lighting concept originated in Europe with the purpose of allowing people to live in a comfortable lighting environment. LED is an easy-to-adjust light source, which can adjust the light according to the biological cycle, but the spectral distribution and color temperature conditions still need to be considered.
Although lighting is not the only factor that affects the circadian rhythm (circadian rhythm), it is the key factor. Some scientists believe that lighting can affect people's mood, health and energy.
The pros and cons of Humans Factor In Lighting
Humans Factor In Lighting has its advantages and disadvantages. For example, blue light belongs to cold white light, which is close to natural light, causing concentration. It can replace student classrooms and offices. However, being exposed to blue light will also inhibit melatonin (melatonin). ) Growth, and affect sleep quality, immune system, and may cause physical diseases such as cancer.
According to scientific research, blue light can control insulin's polyoligonucleotide. Therefore, if you are exposed to blue light for a long time at night, it will cause resistance (insulin resistance), that is, weight loss and blood sugar can not be controlled, and this phenomenon will lead to obesity , Diabetes, hypertension and other diseases.
Lighting design cannot only consider color temperature
When designing LED lighting, the spectral energy distribution and color temperature should be considered. The color temperature is in absolute temperature K. The color temperature of blue light in the spectrum of different light sources falls above 5300K, which is a medium-to-high color temperature with a bright feeling; on the contrary, red Light, yellow light belongs to warm color light, the color temperature is below 3300K, which makes people feel warm, healthy and relaxing, suitable for home use.
However, under the same color temperature, different viewers and other conditions such as climate, environment and other factors will have different spectral distributions. Therefore, Deborah Burnett, consultant of Benya Burnett lighting design company, believes that the spectral energy distribution (Spectral Energy Distribution, SED) is the key factor affecting the human eye and body.
