LED Lighting Has A Great Influence on Life
Humans Factor In Lighting, also known as comfort light, refers to the adjustment of light according to the person’s daily routine. This kind of lighting concept originated in Europe with the purpose of enabling people to live in a comfortable lighting environment. LEDs are easy-to-adjust light sources that can adjust the light in accordance with the biological cycle, but still need to consider spectral distribution and color temperature conditions.
Lighting, though not the only factor affecting the circadian rhythm (Circadian Rhythm), is the key factor. Some scientists believe that lighting can affect people’s mood, health and energy.
Pros and Cons of LED Lighting
The use of LED for human illumination has both advantages and disadvantages. For example, Blu-ray is a cool white light that is close to natural light and helps to concentrate, which is suitable for student classrooms and offices. However, exposure to blue light for a long time can also inhibit the growth of melatonin, affect the quality of sleep, the immune system, and may cause body lesions such as cancer.
According to scientific research, blue light can control the amount of insulin, so if long-term exposure to blue light at night, will cause insulin resistance phenomenon, that is, reduced insulin, cannot control blood sugar, and this phenomenon will lead to obesity, diabetes, high blood pressure and other diseases.
Lighting Design Shouldn’t Include Color Temperature Only
In the design of LED, the spectral energy distribution and color temperature should be taken into account . The color temperature of blue light falls above 5300K, which belongs to medium-high color temperature and has a bright sense. On the contrary, red light and yellow light belong to warm-colored light. The color temperature is below 3300K, making people feel warm, healthy and relaxed, and suitable for home use.
However, under the same color temperature conditions, there are different spectral distributions due to different viewers and other conditions such as climate, environment and other factors. Therefore, Deborah Burnett, an adviser to Benya Burnett Lighting Design Inc., believes that the Spectral Energy Distribution (SED) is the key factor affecting human eyes and body.
