LED lighting design can not only consider the color temperature

Humans Factor In Lighting, also referred to as comfort lighting, refers to the lighting that adjusts as people work and rest, and this lighting concept originated in Europe with the purpose of living in a comfortable lighting environment. LED is easy to adjust the light source, can adjust the light with the biological and physiological cycles, but still need to consider the spectral distribution and color temperature conditions.

The only factor in Circadian Rhythm is the key factor. Some scientists believe that lighting can affect people's emotions, health and energy.

The LED used in human lighting has its advantages and disadvantages, such as blue light is cool white, close to natural light, help to concentrate, can be used in student classrooms, offices; but for a long time by the blue light will also inhibit melatonin (Melatonin) growth, and affect the quality of sleep, the immune system, but also may cause physical diseases such as cancer.

According to scientific research, blue light can control the amount of insulin, so long-term exposure to blue light at night can cause insulin resistance, that is, insulin is decreased, unable to control blood sugar, and this phenomenon can lead to obesity, diabetes, high Blood pressure and other diseases.

In the design of LED lighting should take into account the spectral energy distribution as well as color temperature, color temperature in absolute temperature K as a unit, representing the spectral components of different light sources. Blue color temperature falls above 5300K, belong to the high color temperature, a sense of bright; on the contrary, red, yellow are warm colors, color temperature below 3300K, people have a warm, healthy and relaxing feeling, suitable for home use.

However, the same color temperature conditions, but also because of different viewers and other conditions such as climate, environment and other factors, and have different spectral distribution. Therefore, Deborah Burnett, consultant for Benya Burnett Lighting Design, believes that the spectral energy distribution (SED) is the key factor affecting the human eye and body.
