The application of LED lighting to human-induced lighting has its advantages and disadvantages. For example, blue light belongs to cool white light, which is close to natural light and helps to concentrate. It can be used in student classrooms and offices; however, long-term exposure to blue light will also inhibit fading. The growth of melatonin affects sleep quality, immune system, and may cause physical diseases such as cancer.

According to scientific research, blue light can control the amount of insulin, so if you are exposed to blue light for a long time at night, it will cause insulin resistance (insulin resistance) diseases such as blood pressure.

Lighting design can not only consider color temperature

When designing LED lighting, the spectral energy distribution and color temperature should be considered. The color temperature is based on the absolute temperature K, which represents the spectral components of different light sources. The color temperature of blue light falls above 5300K, which is a medium-high color temperature and has a bright feeling; on the contrary, red light and yellow light belong to warm color light, and the color temperature is below 3300K, which makes people feel warm, healthy and relaxing, suitable for home use.

However, under the same color temperature conditions, there will be different spectral distributions due to the influence of different viewers and other conditions such as climate and environment. Therefore, Deborah Burnett, consultant of Benya Burnett Lighting Design Company, believes that the spectral energy distribution (SED) is the key factor affecting the human eye and body.
