human body Ergonomics

As a huge potential for development of the light source, long life LED, firm structure, low power consumption and flexible dimension has been more and more attention in recent years, LED especially monochromatic LED is widely used in large screen, signal lamps and landscape lighting. With the continuous development of LED technology, white LED light effect, color, color temperature and a single LED power and LED module flux continuously made new breakthroughs, the application of the LED in the traditional areas of lighting, full of expectation.

However, the white LED applied to ordinary indoor lighting is also facing a series of challenges, such as single LED luminous flux is difficult to meet the needs of general lighting, unit cost, high light efficiency than energy-saving lamp is low, large color difference, lack of stability, although the manufacturers of laboratory research results again and again refresh, but for the real with the lighting requirements of market-oriented products still need some time, this is the LED R & D personnel, manufacturers and users cannot evasive fact. This article from the illumination of the human body ergonomics point of view, analysis of the current development status and health of white light LED light environment needed for normal index between the difference of existence, to promote LED in the application of indoor lighting process put forward certain proposal.

Illumination of the human body Ergonomics
Human ergonomics also called ergonomics and human engineering, in order to" man machine environment" system as the research object, through the measurement, statistics, analysis and other methods, study of" man machine environment system of" people, machine, environment of the three elements and the relation between, to solve the system 's efficiency, health problems. That is to say, human ergonomics research focuses on the design and evaluation of human needs, the ability of people, people with various tasks, limit how work, products, environments and system coordination. Illumination ergonomics is the study of the human body, light environment design to meet the needs of the people, make people faster and better to complete the visual operation or as far as possible to meet the comfortable and healthy demand.

Lighting environment should fully consider the needs of the people, the need to include both to meet people's visual function, so that people could fit in a visual environment of the normal work, popular as can see clearly; and to meet people's psychological needs, i.e., to look at. A recent study showed that light can, by influencing people in melatonin secretion and influence human body physiological rhythm and health. Therefore, in consideration of the human body ergonomics of good lighting environment should be from the visual, psychological and physiological needs, consider a number of factors, or to the people's working efficiency, mental or physical health will cause adverse effects.
