With the development of society, green engineering has become more and more concerned by countries all over the world. In 1991, the US government proposed the 'green lighting project'. plan. In 1995, the State Council of China drafted the Energy Conservation Law and submitted it to the Standing Committee of the National People's Congress for deliberation. 'China's green lighting project' main content includes: the formulation of China's green lighting regulations, regulations; the use of high light efficiency, good light color, long life, safety and stable performance of the electric light source; use its own low power consumption, low noise, the environment Electrical accessories for lamps with no pollution and influence on the human body; lighting fixtures with high light energy utilization, good durability, safety and beauty; high transmission efficiency, low efficiency, low power loss, safe and reliable power distribution equipment and energy-saving adjustment Light control equipment, etc. Here, we will only do some research on technical issues. 1 Establish and improve technical basic work with high efficiency and energy conservation (1) Establish and improve energy-saving lighting standards. For example, the maximum lighting power consumption standard per square meter of the lighting place or the illumination standard of different lighting places is specified. (2) Establish and improve safety and technical quality standards for high-efficiency lighting energy-saving products; such as tungsten halogen lamps, fluorescent lamps (including straight tube, ring type, compact type and profiled), high-intensity gas discharge lamps (including high-pressure sodium lamps, metals) Halide lamps, etc.); electrical accessories for lamps (ballasts, transformers, etc.); lamps; wiring equipment and light control equipment and devices. (3) Establish and improve the safety and quality certification systems and systems for energy efficient lighting products. Adopting high-efficiency and energy-saving light source In most cases, the electric light source is the core and main body of high-efficiency energy-saving in lighting design. Therefore, the correct and reasonable choice of light source is the key to realize green lighting. Table 1 lists the light efficiency comparison tables for various types of electric light sources. It is apparent from Table 1 that the luminous efficiencies of different light species vary greatly. Ordinary incandescent lamps, although of good color, have extremely low light efficiency and have a lifetime of only 1/5 to 1/12 or less of fluorescent lamps. Table 1 luminous efficiency of various types of power supply t: lamp luminous efficiency (Lm / w) lamp luminous efficiency (Lm / w) incandescent metal halide lamp mercury lamp rolling sodium lamp fluorescent lamp high frequency electrodeless lamp in the implementation of green lighting plan In the middle, how to choose the light source, everything must start from the national conditions of China, and seek truth from facts. Some lighting places can be in place in one step. After construction or transformation, they can directly reach the international advanced level, while others need to go through excessive and step by step. Several light source options. 2.1 Replace the ordinary lighting incandescent tungsten halogen lamp and the ordinary incandescent lamp with the halogen halogen lamp. The incandescent lamp products are all powered by the incandescent light. Tungsten halogen lamp is an upgraded product of ordinary incandescent lamp. Although ordinary incandescent lamp has the characteristics of convenient installation and relatively low price, its low light efficiency is its fatal weakness. The halogen light effect and life is higher than ordinary incandescent lamp. More than double. Therefore, in many lighting places where high color rendering is required, halogen lamps of various structures can be used instead of ordinary incandescent lamps to achieve energy saving and improved lighting quality. 2.2 Replacing incandescent lamps with compact fluorescent lamps (energy-saving lamps) The practicality and aesthetics of modern high-quality, energy-efficient compact fluorescent lamps have attracted people's attention. The replacement of incandescent lamps with compact fluorescent lamps can save 655~755 lighting costs. The luminous flux per watt is 3 times to 4 times that of ordinary lighting incandescent lamps, and its rated life is 10 times that of incandescent lamps. Due to the continuous improvement and improvement of the quality of phosphors, the color rendering index of compact fluorescent lamps can reach about 80, which is completely satisfactory in general lighting conditions. Compact fluorescent light with high efficiency, good color, long life and easy installation is one of the best light sources to replace ordinary incandescent lamps. 2.3 Replacing incandescent lamps with straight tube fluorescent lamps The luminous efficacy and lifespan of fluorescent lamps are more than five times that of ordinary incandescent lamps. Instead of incandescent lamps, they are widely used in commercial, school, small and medium-sized conference rooms and home lighting. 2.4 Promote the application of high-pressure sodium lamps and metal halide lamps High-pressure sodium lamps and metal halide lamps, which are high-intensity gas discharge lamps, have high luminous efficiency and long life, and are the best choice to replace high-pressure mercury lamps. Table 2 compares the luminous efficacy of several specifications of high-pressure beam lamp, metal halide lamp and high-pressure sodium lamp: Table 2 Mercury lamp and d-form lamp, sodium light effect comparison table species mercury lamp metal halide lamp (Lm/w ) Sodium-alkali lamp (Lm/w) According to the above data, it is easy to see that the use of a metal halide lamp or a high-pressure sodium lamp instead of a mercury lamp can achieve an energy-saving effect or an improvement in the level of illumination. Another advantage of the high-pressure sodium lamp and the metal halide lamp is that the discharge tube as the illuminant has a relatively small size, so that the optical control of the output light is easily realized, which is advantageous for improving the light energy utilization rate of the output light of the luminaire and increasing the output light. Projection distance. Metal halide lamps have good color rendering properties, and in some production sites, metal halide lamps can be used instead of fluorescent lamps. For the renovation of the lighting, the specially designed metal halide lamp can work normally on the original mercury lamp ballast, which can generate more than 201 energy savings. 2.5 Application of low-pressure sodium lamp The light effect of low-pressure sodium lamp is the first of all kinds of lamps. However, its color rendering is extremely poor, and it can be applied to tunnels and other lighting places where color reproduction is not demanding. Starting from the implementation of green lighting projects, the production and development of low-pressure sodium lamps is still a gap that needs to be filled in China. High-efficiency and energy-saving lamp electrical accessories At present, the low-voltage tungsten halogen lamps used in most cases require additional transformers, and the gas discharge lamps must be equipped with ballasts, starters, triggers and other electrical accessories when working. When implementing a green lighting plan, you must pay attention to the selection of energy-efficient electrical accessories that match the light source. With the advancement of green lighting work, power electronics has entered the field of electric light sources, gradually forming a new science. The most prominent of the "Electronics for Lamps" is the development and promotion of electronic ballasts. The advantages of the electronic ballast are: (1) improving lamp efficiency by high frequency; (2) instantaneous lighting; (3) no stroboscopic; (4) no noise; (5) low power consumption; (6) Small size and light weight; (7) Dimming and the like can be realized. Adopting high-efficiency energy-saving lighting fixtures At present, the commonly used lighting fixtures, optical systems that transmit light energy, mostly adopt reflective structures. However, whether it is a reflective luminaire or other types of refracting and folding combined luminaires, in addition to the correct selection of materials, processes, and optical design, in consideration of improving the utilization of light energy, it is necessary to consider other aspects. Such as glare and other light pollution to the environment. According to its practice, the standard green fluorescent lamp has a light output efficiency of 651, while the deep parabolic fluorescent lamp has a light output efficiency of 84%. The use of various energy-saving control devices and Wiring equipment in various specific lighting places, in order to save energy, according to the needs of the environment for lighting, such as the light source on, off or illuminance changes, etc., can be adjusted by various dimming equipment or light control control. Several commonly used methods are: (1) light sensor; (2) human sensor; (3) time program control; (4) direct or remote dimming. When selecting wiring equipment and other devices, attention should be paid to high transmission efficiency, long service life, low power loss, safety and reliability, and low environmental pollution.

It is the obligation of each of us to promote the knowledge of green lighting and protect the global environment. We hope that we will work together to promote the development of China's green lighting industry.
