The pinnacle of contemporary shaping of light - digital semiconductor lighting (2)

Digital semiconductor lighting is a new opportunity and a new challenge. The digital semiconductor lighting industry has enormous economic, technological and social benefits and has the potential to innovate. These innovations will improve the quality of life of people and create a green and sustainable society. Let us build consensus, promote the innovation and development of semiconductor lighting with higher enthusiasm and more positive actions, and create a bright future!

Chapter 2 The past and present of digital semiconductor lighting

With the rapid development of semiconductor lighting technology, semiconductor lighting applications have entered the era of digital, intelligent and networked. The digital and remote monitoring requirements in the field of lighting are becoming more and more clear. Digital, network and remote monitoring have become the technology of lighting. Standard configuration.

First, shaping the light

(1) Natural light and shaping light

The source of light, there is natural light and shaping light.

Natural light: visible light in nature, without the aid of any human aids, the light source emitted by natural phenomena, natural light can only choose to wait, but can not be changed by means of material tools. Lights such as sunlight, fire, and lightning are usually generated by high temperatures and have a wide spectral range.

Shaping light: In the course of development, human beings use the characteristics of various substances, and the light produced by artificially designed instruments and equipment, such as the light of fluorescent lamps, lasers, and light emitted by LED lamps.

Natural light and shaped light are essentially different:

1. Variability

The most important essential feature of natural light is that it is immutable. The intensity and direction of natural light cannot be arbitrarily adjusted and controlled. It can only be passively adapted according to natural phenomena, while shaping light can be changed at any time according to different human needs. Choose and not choose, choose what kind of shaping light, choose what intensity to shape the light, when to choose, etc.

2, to achieve different functions

Natural light has the characteristics of not changing due to human will. It can not be customized and managed by human beings, so it can only meet the single lighting needs of people. The shaping of light can meet the different needs of people according to different fields, different environments and different subjects. It can meet the diverse needs of people in addition to a single lighting demand.

(2) The demand for light by human beings, the times and society

1. Different subjects, different fields, and different environments each have different needs.

Invisible light is the foundation of all things, and all visual existence depends on the illumination of light. Different subjects, different fields, and different environments each have different needs.

Light is an immaterial existence that cannot be seen directly but illuminates an object. The shape of the light is roughly shaped by a lighting tool or illuminator.

2, light shaping → the presentation of light quality → the formation of light demand

Shape the shape of light:

(1) shaping the shape of light through the form of the interface, ie indirect illumination

(2) The shape of light shaped by the lamp

(3) The shape of the illuminator shaping light

Presentation of light quality:

(1) Indirect lighting is characterized by uniform and soft light, strong layering, no glare, no glare, no obvious shadow, good expressiveness, and good at creating a quiet and peaceful environment.
