LED lighting emphasizes the concept of the development of industry standards as a priority

Lighting is a kind of comprehensive engineering technology which involves many subjects and many technical fields. The human visual characteristics and visual cognition determines the amount and the pursuit of the quality of lighting, not only to consider the development of its own technology, but also a comprehensive consideration and attention of philosophy, aesthetics, ergonomics, physiology and psychology and other fields to meet the needs of the end customer.

The development of semiconductor lighting technology and industry is much faster than expected, some of the optical properties of LED is any artificial light can not match, such as rich color, high color saturation, wide color gamut, concentrated light beam, fast response speed, brightness and color of intelligent network control and regulation etc.. The application of these new characteristics will change the traditional lighting experience and habits, LED lighting concept and light the change of culture, to promote the lighting products to people-oriented and more humane direction, to meet the people's physical and mental health needs.

Lighting should take into account the physical and psychological effects

The purpose of lighting in the past is to meet the needs of people in the dark for light, in 1879 Edison invented the incandescent lamp is a symbol of human civilization into modern civilization. Lighting is the first to meet the people can see objects and scenery, followed by the demand for different working surface, the light source has different brightness and illumination requirements, but in general lighting is part of the building electrical.

LED light is a symbol of modern lighting, to study the influence of different colors and color saturation LED lighting on people's physiological and psychological, physiological and psychological effects of optical optical effects on the optical properties and the study of the LED collaboration, especially the human circadian rhythm (biological clock) and endocrine system to a great extent by adjusting the lighting. To study what LED light secretion would stimulate or inhibit cortisol, cortisol uplifting, increase vitality, what LED light will stimulate the secretion or inhibition of melatonin and melatonin will make people sleepy, be sleepy straws. Therefore, modern lighting purposes have a qualitative change, to meet the different people's visual physiological and psychological health, safety and comfort needs, need to adjust the psychological mood and sentiment, need to regulate circadian rhythm and endocrine system.

Development of the lighting industry should break through the traditional concept

In the process of lighting industry towards modern lighting, there are a number of traditional concepts need to break through.

1 break through the concept of traditional light bulb and lamp based lighting, develop surface light source.

Incandescent light source has been used for over 100 years, become people's traditional habits, but the light bulb is relatively concentrated, too bright will produce dazzling feeling, light is soft, uneven lighting face, light design in order to overcome the shortcomings of the above special distribution. The LED light source can be made into a two dimensional surface light source, and a light emitting panel is formed in the form of a backlight source. According to the needs of the size can be small, brightness, color temperature and color can be adjusted to avoid the glare of the traditional lamp, the light is more soft and uniform comfort.

2 break through the concept of imitation of the sun, the development of digital adjustable color light combination lighting system.

Artificial light source must imitate the sun is a question worth exploring, no sunlight at night, lighting can be different according to different needs of different light sources. A typical light source should be a combination of RGB three colors can be a mild color rendering of light source lighting system, according to the needs of different groups, to adjust the brightness and color. Color light can regulate people's mood and mood, relieve pressure, arouse interest, eliminate fatigue and promote health. LED light can be effectively treated SAD (seasonal affective disorder), skin diseases; violet blue light irradiation can accelerate the formation of vitamin A, D, and promote the absorption of calcium, blue to jaundice; India medical D.P.Chadiali with allergic reaction, 12 kinds of light irradiation in the treatment of human immune system disorders, cardiovascular disease, mental tension, depression and insomnia etc.. Therefore, modern lighting is based on different people's physiological and psychological needs of the regulation of digital light color combination lighting system.

3 break through the concept of traditional street lamps, the development of humanized LED street lighting system.

General Expressway and main roads of the city street lamp pole height is 12-15 meters, in fact, street lamp pole height Low more close to a sense of warmth. The LED street lamp is not necessary to make the shape of the sodium lamp, and can be made into the light distribution of the scattered light source, and the height lamp cap is made into a linear light source. Due to the requirements of urban greening, many street lights in the tree, there is no effective use of light energy, resulting in a lot of waste. In the car on the road branch, mixing can be set up in the middle of the road street, Hung Road along the midline, uniformly and effectively utilize light, on both sides of the lamp rod made of cylindrical light, low light, a scattered light source, LED light source can more fully play its strengths and advantages, more humane.

4 break through the traditional concept of object color, high saturation color lighting will bring a new level of visual cognition.

Usually objects with different light source (different spectral mixture) irradiation, can show different colors. In the past, both the light source and the sun, people are accustomed to the object color is also in the standard sunlight. The color and color of the object are determined by the reflectivity of the object and the intensity of the light source
