LED lighting can not only take into account the color temperature, be careful to be the reverse effect

Human illumination can also be called comfort lighting, which means that lighting is adjusted along with people's work and rest. The idea of lighting originated in Europe, so that people can live in comfortable lighting environment. LED is an easy - to control light source, which can adjust the illumination with biological cycle, but it still needs to consider the spectral distribution and color temperature condition.


Lighting is not the only factor that influences the circadian rhythm, the key factor is. Some scientists believe that lighting can affect people's emotions, health and energy.


The advantages and disadvantages of LED people for lighting


LED application for lighting has its advantages and also has some disadvantages, such as blue is cold white light, natural light, help to concentrate, can be applied to the students in the classroom and office; but long time by blue light will also inhibit the growth of melatonin (melatonin), and affect the quality of sleep, the immune system the body, but also may cause diseases such as cancer.


According to scientific research, can control the amount of insulin blue, so if at night by the blue light, will result in insulin resistance (insulin resistance) is a phenomenon, unable to control blood glucose, insulin, and this phenomenon will lead to obesity, diabetes, hypertension and other diseases.


Lighting design can not only consider color temperature


In the design of LED lighting, the spectral energy distribution and color temperature should be taken into account. The color temperature is K at absolute temperature, representing the spectral components of different light sources. The color temperature of blue light falls above 5300K. It belongs to the middle and high color temperature. It has bright sense. On the contrary, red and yellow light belong to warm color. The color temperature is below 3300K, which makes people feel warm, healthy and relaxed. It is suitable for household.



However, under the same color temperature conditions, there will be different spectral distribution because of the influence of different viewers and other conditions, such as climate, environment and other factors. Therefore, Deborah Burnett, consultant of Benya Burnett lighting design company believes that the energy distribution of Spectral (energy distribution, SED) is the key factor that affects human eyes and body.
