From the development trend of interior lighting on LED technology upgrade

LED semiconductor light-emitting diode, is one of the largest and most active high-tech industries in twenty-first Century. This paper tries to explore the key LED technology promotion from the development trend of interior lighting, hope that under the joint efforts of the industry, to promote the healthy and orderly development of the LED industry in china.

Preface

According to StrategiesUnlimited statistics, the development of LED indoor lighting in the next 5 years showed an exponential growth trend. It is estimated that by 2011, its output value will reach tens of billions of dollars. This is for LED indoor lighting, is both an opportunity and a challenge. According to the development trend of indoor lighting, it is necessary to improve the LED technology.

Classification of indoor lighting

1 by lighting classification

(1) direct lighting

The so-called direct lighting refers to a light emitted by the lamp, 90%-100% luminous flux at the face on the assumption that contrast light strong and vivid light effect, can highlight the dominant position in the whole working face in the environment, mainly used in the workplace.

(2) semi direct lighting

The so-called semi direct lighting is a light shade covering upper is made of translucent material, which makes the 60%-90% more concentrated light at the working face, in addition, cover light will 10%-40% the ratio of diffusion to diffuse translucent shade. The light generated by the lighting method is relatively soft, and the diffused light can increase the sense of space of the building.

(3) indirect lighting

The so-called indirect lighting refers to the lighting light shielding indirectly produced, the luminous flux of 90%-100% through reflection on the ceiling or wall surface, less than 10% of the light shines directly on the working surface of the rest. Generally speaking, this kind of lighting can only be used with other lighting methods to obtain special artistic effects, mainly used in shopping malls, clothing stores, meeting rooms, etc..

(4) semi indirect lighting

Compared with the semi direct lighting, semi indirect lighting is a lighting mode completely opposite. Specifically, the semi transparent lamp installed in the lower part of the light source, more than 60% of the light to form a flat, the rest of the indirect light source, 10%-40% light shade by downward diffusion. This method can produce a more obvious lighting effect, so that the room has a low rise in a certain sense of increase. The utility model is mainly suitable for a small part of a house, such as a hall, an aisle, etc..

(5) diffuse lighting

Diffuse lighting refers to the use of light refraction function to control glare, which will spread to the surrounding light. There are two forms of this kind of illumination, one is that the light is emitted from the top of the lampshade and the flat top is reflected. The other is to use a translucent lampshade to close all the light and diffuse. The light generated by this kind of lighting is visual and comfortable.

2 by lighting type

Integrated lighting: the overall indoor lighting is designed to illuminate the interior space to allow people to distinguish the interior furnishings, channels and doors and windows.

Key lighting: the use of spotlights on the walls of the decorative painting or on the table, the items inside the cabinet to be prominent, eye-catching, making it a visual center.

Auxiliary lighting: mainly with the use of key lighting for a number of statues, crafts and other lighting.

Lighting level: facade design is mainly applicable to the level before and after more, in a lamp is not up to the requirements of lighting effect, adding lights and front lamp, two layer decorative backlight for modification, so as to achieve the purpose of strengthening the sense of hierarchy.

The three-dimensional lighting: mainly in the interior space of different directions and angles to install various types of lamps, even the installation of lamps behind furniture and people in the bottom, aims to enhance the sense of interior space, suitable for gatherings or crowded places and to create an atmosphere.

Decorative lighting: in the indoor use of color light source, neon tube, plastic light or optical fiber and laser, etc., made of pure decorative lighting graphics and text.

Generally speaking, in the office of the general use of the overall lighting (basic lighting, environmental lighting), and in the home and shopping malls, bars and other places will be the use of a combination of several lighting methods.

Two, the development trend of indoor lighting

Different light can produce a different sense of space, good light effect can produce a better sense of space, people feel happy, otherwise it will make people feel depressed and unhappy. The interior lighting is one of the most popular lighting, the design of the people's daily lives and work directly affect the importance of self-evident. It is worth noting that, in the efforts of the industry, indoor lighting is becoming more and more healthy and orderly direction, the following several major trends are discussed as follows:

1 energy

In the field of indoor lighting energy saving, European and American countries attach importance to the early. In the early 90s, the United States Environmental Protection Agency launched the identification system of the commodity such EnergyStar, to conform to the standard of energy saving products labeled with Green Star label, and entered the United States Environmental Protection Bureau to promote the catalogue. The U.S. energy independence and security act of 2007 (theEnergyIndependenceandSecurityActof2007) promulgated, the consumption of energy in the United States in May 2008 greatly reduced, at the same time further prompted the U.S. Department of energy DOE BrightTomorrowLightingPrize (LPrize) in the form of competition to encourage and promote lighting manufacturers
