Green lighting is a concept put forward by the US Environmental Protection Agency in the early 1990s. The complete green lighting connotation includes four indicators, such as high efficiency, energy saving, environmental protection, safety and comfort, which are indispensable. Energy-efficient means that you can get enough lighting by consuming less electric energy, which can significantly reduce the emission of air pollutants from power plants and achieve environmental protection. Safety and comfort mean that the light is clear, soft and does not produce harmful light such as ultraviolet rays and glare, and does not cause light pollution.
1. Green lighting projects require people not to simply think that it is just energy saving, but to understand from a higher level, to improve energy conservation and environmental protection, so that the meaning is broader, farther away, some areas, some units may I believe that the power supply is not so tight now, and lighting power saving is not so important. This simple understanding is that energy conservation is not recognized from the height of environmental protection, because the purpose of the green lighting project is not only an economic benefit, but more important. It is a big topic that focuses on the use of resources and environmental protection. By lighting energy saving, thereby reducing the amount of power generation, that is, reducing the amount of coal burned (more than 70% of China's power generation is still dependent on coal), to reduce emissions of harmful gases such as S02, CO2 and nitrogen oxides, facing the world's environment and The subject of development has far-reaching significance.
2. Green lighting engineering requires lighting energy saving, which is not completely energy saving in the traditional sense. This has been clearly described in the “Green Lighting Project Implementation Plan†in China, which is to meet the lighting quality and visual environmental conditions. High requirements, therefore can not rely on reducing lighting standards to achieve energy savings, but to fully use modern technology to improve lighting engineering design level and square weeping, improve lighting equipment efficiency to achieve.
3. The implementation of green lighting project can not be simply understood as providing high-efficiency energy-saving lighting equipment. Efficient equipment is an important product of the future green lighting, the leading product of LED lighting series (19 photos), but it should be correct and reasonable. Lighting engineering design. The design is unified and overall, and it plays a decisive role in the implementation of green lighting requirements. In addition, the operation and maintenance management also has many neglected functions. Without this factor, the implementation of lighting energy conservation is not complete.
4. Efficient lighting equipment is an important basis for lighting energy conservation, but lighting equipment is not just a light source. Light source is the primary factor that has been recognized by people, but not unique, the efficiency of lamps and electrical accessories (such as ballasts), energy saving for lighting. The impact can not be ignored, this is often not noticed, such as a diffuser with a diffuser, or a straight tubular fluorescent lamp with a grille, high efficiency and high quality products can be more efficient than low quality products 50% to 100%, which shows its energy-saving effect.
5. High-efficiency light source is the primary factor in lighting energy conservation However, some people simply promote the promotion of high-efficiency light sources to promote energy-saving lamps (where the energy-saving lamps are specifically for compact fluorescent lamps), which is very incomplete and very harmful, because there are many types of decorative energy-saving lamps. Efficient people should be promoted. In terms of energy conversion efficiency, it has the same performance as compact fluorescent lighting (such as straight tube fluorescent lamps), and has higher luminous efficiency (such as high-pressure nano lamps, metal halide lamps). These high-efficiency light sources have their own characteristics. And the advantages, each with its applicable place, is by no means simply replaced by a kind of energy-saving light source. According to the application site conditions, at least three types of high-efficiency light sources should be promoted.
6. Efficient lighting tool Light guide lighting system consists of three parts: lighting cover, light pipe and diffuser. The principle of illumination is to efficiently collect outdoor natural light through the hood and redistribute it into the system. After the specially produced light pipe is transmitted and strengthened, the natural light is evenly and efficiently illuminated into the interior of the venue by the diffuser at the bottom of the system, thus breaking the " The concept of lighting relies entirely on electricity.
Drainboard sinks are sinks that have an attached drainboard usually on one side but sometimes on both sides. This drainboard is grooved and slightly angled down so that water drains directly into the sink while dishes are resting on it. It is a kitchen accessory that helps you to dry your dishes.
