Human-caused lighting has been very popular in recent years. This is because with the improvement of people's requirements for light quality, the future development of lighting will tend to human-oriented human-oriented lighting. Human-oriented lighting refers to the creation of lighting art that simulates natural daylight that improves human body functions. It can improve human body function, comfort, health and happiness. It goes beyond smart and healthy lighting, and more precisely, it is a partial combination between the two.
There are five key factors to realize human lighting: one is the spectrum, which determines the color temperature, CRI, blue light intensity, etc., which play a decisive role in the final effect; the second is the illuminance, which is the most intuitive experience of the user and affects the user’s Feeling of use; third is the light distribution, according to aesthetic needs, the distribution is in the right place; fourth is the lighting time, that is, lighting at the right time to prevent light pollution; fifth is the lighting time, which will affect the user's mood.
Traditional LED light sources have the problem of damage to the retina by short-wave blue light in terms of visual effects, and problems such as circadian rhythm disorders in terms of non-visual effects. Human-caused lighting can reduce the proportion of harmful short-wave blue light, relieve visual fatigue, and intelligently fit the solar spectrum to adjust human normal circadian rhythms.
Therefore, we can see that to realize the challenges faced by human lighting, not only excellent optical design, but also a complete intelligent control and data analysis system, and a good LED light source are needed.
Human lighting has a wide range of applications, and different groups of people have differentiated needs.
For classroom lighting, it is necessary to protect eyesight, reduce blue light hazards, help students improve learning efficiency, and even apply to different learning modes. This requires products to reduce blue light content, with high color fidelity, high saturation and continuous spectrum.
For office lighting, it must have high alertness, high CRI and circadian rhythm adjustment functions to meet the needs of office workers for simplicity, efficiency, comfort, softness, strong color rendering, less blue light, and brightness adjustment during work and rest.
Home lighting is mainly warm white, which can simulate continuous spectrum, reasonable spectral energy distribution can affect melatonin level, can increase room illuminance, improve brightness uniformity, and the color temperature is warmer, the color rendering is enhanced, and glare and light mutations are reduced sex.
In addition, the lighting used in the hospital is soft and comfortable, which can adjust sleep and simulate sunlight; the lighting used in the restaurant has high design, adjustable color temperature, and high color rendering, allowing guests to feel privacy and comfortability. Landscape lighting products have high design, significant projection effects, and rich colors. They are compact LEDs, which not only have lighting functions, but also value artistic conception and sensory enjoyment.
