Green lighting is an internationally accepted image of a lighting source with the concept of saving energy, saving resources, and protecting the environment. It mainly refers to the use of high-efficiency, long-life, safe and stable performance lighting electrical products through scientific lighting design, such as electric light sources, lamp electrical accessories, lamps, etc. to improve people's working, learning, and living conditions and quality , So as to create an efficient, comfortable, safe, economical and beneficial environment and fully reflect the lighting of modern civilization.
Green lighting includes four indicators of high efficiency, energy saving, environmental protection, safety and comfort. High-efficiency and energy-saving means obtaining sufficient lighting with less power consumption, thereby significantly reducing the emission of air pollutants from power plants and achieving the goal of environmental protection. Safety and comfort refer to clear, soft and no harmful light such as ultraviolet rays and glare, and no light pollution.
The green lighting project requires people not to confine themselves to the awareness of energy conservation, but to raise it to the height of energy conservation and environmental protection, so that the impact can be broader and more far-reaching. The green lighting project is not only a question of economic benefits, but also a major issue focusing on resource utilization and environmental protection. Saving electricity through lighting reduces the amount of electricity generated, thereby reducing the amount of coal burned, reducing the emission of harmful gases such as sulfur dioxide, nitrogen oxides, and greenhouse gases such as carbon dioxide, which will help solve the environmental and development issues facing the world.
The lighting energy-saving required by the green lighting project is not completely energy-saving in the traditional sense. This is clearly described in the purpose of China's "Green Lighting Project Implementation Plan", which is to meet the higher requirements of lighting quality and visual environmental conditions. Therefore, the realization of lighting energy saving cannot rely on lowering the lighting standards, but rely on the full use of modern technology to improve the level of lighting engineering design and the efficiency of lighting equipment.
Q2. What measures can we take to achieve green lighting?
To achieve green lighting, it is first necessary to reasonably use electric light sources, electrical accessories, lamps, wiring equipment, and dimming and light control devices.
For example, we can use high-efficiency and energy-saving electric light sources; use high-efficiency energy-saving lighting fixtures; use high-efficiency energy-saving lamps and electrical accessories; use various lighting energy-saving control equipment or devices.
Bird: What is the difference between an electric light source and a lamp?
Dog: Electric light source is a device or device that converts electrical energy into light energy; lamp is a device that redistributes the luminous flux emitted by the light source, prevents and reduces the pollution of the light source, and protects the light source.
Q3. What are the high-efficiency and energy-saving electric light sources?
1. Tungsten halogen lamp: replacing general lighting incandescent lamps with halogen tungsten lamps can save electricity by 50-60%;
2. Self-ballasted single-ended fluorescent lamps: replacing incandescent lamps with self-ballasted single-ended fluorescent lamps can save power by 70-80%;
3. Straight tube fluorescent lamp: replacing incandescent lamp with straight tube fluorescent lamp can save 70-90% of electricity;
4. High pressure sodium lamp and metal halide lamp;
5. Low pressure sodium lamp;
6. Light-emitting diode-LED.
Q4. What are high-efficiency and energy-saving lighting fixtures, high-efficiency energy-saving lamp electrical accessories, and energy-saving lighting control equipment or devices?
Efficient and energy-saving lighting fixtures refer to:
Reflective lamps with reasonable light distribution, high reflection efficiency, and good durability, as well as lamps coordinated with light sources and electrical accessories.
High-efficiency and energy-saving electrical accessories for lamps refer to:
Energy-saving inductive ballasts and electronic ballasts.
Various lighting energy-saving control equipment or devices include:
Thermal radiation sensor;
Time program control;
Direct or remote dimming.
Q5. What is the goal of green lighting?
The green lighting project plan is based on protecting the environment and saving resources. Its primary goal is to prevent and control pollution caused by lighting.
The ideal state of green lighting is:
Lighting energy-saving, the production process of light sources and lamps is also conducive to energy saving;
The production of light sources and accessories should save various materials;
The manufacturing process should be environmentally friendly;
The light source is free of harmful rays such as ultraviolet rays;
The parts have good durability;
No electromagnetic interference to the environment;
No harm to the power grid;
The waste can be recycled after failure and does not pollute the environment.
