First, green lighting introduction
Today, with the rapid development of the economy and the improvement of living standards, the people are beginning to focus on the pursuit of a good light environment while pursuing a good living environment. In addition to getting sufficient lighting, they must also get good lighting design and good. Work, good rest, and good environmental protection, the idea of ​​green lighting is like this. Green lighting not only focuses on improving the quality of life, but also on social benefits, focusing on energy conservation itself, while saving energy while improving the quality of life.
Second, the main content of green lighting
1. Develop and apply high-efficiency light sources.
(1) Incandescent lamps and fluorescent lamps: incandescent lamps: good color rendering, low cost, easy to use, low maintenance cost of equipment, currently used in a large number of applications, accounting for about 70% of the total lighting source. However, its luminous efficiency is low and energy consumption is high, which becomes an obstacle in energy-saving lighting. There are about 4.9 million lamps in the Shanwei area. If 20% of these lamps are replaced by high-efficiency lamps, they will save about 19.6 million kWh per year. Fluorescent lamps: high efficiency and long life. It is the most suitable energy-saving light source in the family. Its energy-saving effect is reflected in: a 10W fluorescent lamp is equivalent to a 60W incandescent lamp under the illumination with the same effect. And life expectancy is 5 times longer than incandescent lamps. And its advantage is that it has good color rendering.
(2) Inductive ballast: The traditional inductive ballast indoor lighting has a power of about 9W. The energy consumption accounts for 20% of the total energy consumption of the lamp, and the power factor is low, the energy consumption is large, unstable, and the light is a little flash. At present, the energy-saving magnetic ballast indoor lighting has a power of about 5W, and the energy saving is over 40%.
2. Develop and apply high efficiency lamps. The choice of high-efficiency luminaires should consider two factors, one is the luminaire efficiency, and the actual site conditions should be considered, and the luminaires that meet the requirements should be selected according to the site conditions. Choosing a good luminaire can improve the illumination of the light source, and the utilization efficiency is higher, saving energy and reducing loss.
3. Reasonable lighting method. According to the characteristics of the site and the size of the building, consider the conditions such as the color rendering and color temperature of the light source, and select the appropriate light source type.
4. Strengthen the management of lighting energy conservation. Strengthening the management of lighting energy conservation is mainly to strengthen the management of people, and develop good habits such as turning off the lights and turning off the unnecessary lights. At present, China's management in this area is very weak, and energy waste is very serious.
Third, the personal benefits of green lighting
Green lighting can provide three benefits for individuals to improve their living environment, improve their working environment and save on electricity bills.
1. The application of green lighting can improve the living environment. Green lighting applications can use lighting to create a different atmosphere, either quiet or sweet and light, depending on the characteristics of life. You can use the color rendering of green lighting fixtures to improve the visual effect of the room, especially in some places with room wall decoration; use the color temperature characteristics of green lighting fixtures, choose warm color temperature in the bedroom, create an atmosphere, choose cool color temperature in the living room, Improve illumination.
2. The application of green lighting can improve the working environment. The application of green lighting can set enough space brightness according to the size of the venue. Ordinary lamps can not meet the requirements of large venue and high illumination. According to the use, it can also provide sufficient vertical height in public places such as stadiums; some special For places, rooms, etc., you can also choose different colors of light to adjust the atmosphere. For example, in the workplace, it is necessary to use cold color temperature to improve illumination and improve the sensitivity of the staff. In some places of rest, try to use warm color temperature to improve the sense of belonging of the staff to the work unit.
3, the application of green lighting can greatly save personal electricity costs. Green lighting can greatly reduce the power of the luminaire because of the same illuminance. Therefore, in the case of the same application conditions, the cost of electricity can be greatly reduced. Generally, a 40-watt incandescent lamp and a 15-watt energy-saving lamp have the same illuminance, but 40 hours, the energy-saving lamp can save 1 kWh of electricity, which can reduce the electricity expenses of individual households.
Fourth, the social benefits of green lighting
Whether electricity comes from hydraulic, nuclear or firepower, it is exchanged for environmental and resource costs. Hydropower facilities have changed the ecological status of rivers; nuclear power plants output nuclear waste; thermal power coal produces harmful gases and dust. Therefore, the electricity we consume also puts tremendous pressure on the environment. Therefore, at this level, we should also save electricity, avoid unnecessary waste, and raise awareness of resource concerns and energy conservation in the whole society. Now the whole society is promoting conservation, and green lighting is about saving. If a medium-sized city with 500,000 users replaces all incandescent lamps with energy-saving lamps and near-resident lighting, it can save 50,000 kilowatt hours of electricity, save 19 tons of coal and reduce 1 ton of sulfur dioxide emissions. For the whole society, the significance is huge.
V. Economic analysis of green lighting technology
The following is mainly discussed from the choice of light source, comparing the green energy-saving light source with the traditional light source.
1. The technical and economic comparison between using fluorescent lamps instead of incandescent lamps to install 1ç›40W incandescent lamps and 1ç›15W fluorescent lamps is as follows: 2. Energy-saving magnetic ballasts replace traditional indoor lighting projects with an area of ​​100 square meters. Install a 36W lamp 10ç›, compare the traditional inductor ballast with the energy-saving inductor ballast as follows:
Sixth, some problems existing in current green lighting
At present, China's energy-saving lamp market is chaotic, product quality is mixed, counterfeit and shoddy products are flooding, occupying the energy-saving lamp market, destroying the reputation of green lighting, so that consumers are discouraged from using such products. At present, the state is formulating a series of economic, legal and administrative regulations to regulate market behavior, stop counterfeit and shoddy products from hitting the market, and cultivate a green lighting market that is increasingly accepted by people.
