Lighting can affect people's mood and health
Natural light has a very direct impact on living things. For people, the different effects of lighting on the human body are also obvious due to the difference in ambient light brightness and color temperature. By the way, LED instead of ordinary lighting has its advantages and disadvantages when applied to people. For example, blue light belongs to cool white light around 6000k, which is close to natural light, which helps to concentrate and can be used in student classrooms and offices; but it is exposed to blue light for a long time. It also inhibits the growth of melatonin, affects sleep quality, immune system, and may cause physical diseases such as cancer. Therefore, lighting can indeed affect people's mood, health and energy. According to scientific research, blue light can control the amount of insulin. Therefore, long-term exposure to blue light at night will cause insulin resistance, that is, lower insulin and inability to control blood sugar. This phenomenon can lead to obesity, diabetes, high blood pressure and other diseases. In particular, long-term exposure has more obvious effects on the eyes. For example, mobile phone screens are not good for the eyes when browsing for a long time. The mobile phone screen contains a lot of blue light, which can cause people to fatigue and even get eye cancer. There are already many cases. Therefore, lighting design should 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 5000K, which is a medium-to-high color temperature, with a sense of brightness; red and yellow light is a warm color light, with a color temperature of 2800-3200K, which makes people feel warm, healthy and relaxing, suitable for home use. The reasonable design of lighting is very important. It can affect people's mood and health, and should arouse people's attention.
