Wang Erzhen Huadong Electronics Group Co., Ltd., a green lighting project that has entered the new century. Nanjing, Jiangsu. The 210028 is energy efficient. And pointed out several questions to be solved in the green lighting project.
Green lighting is an integral part of the green environmental protection movement. To be precise, green lighting refers to lighting electrical products with high efficiency, long life, good safety and stable performance, including electric light source lamps, electrical accessories, lighting wiring equipment and dimming control. These scientifically designed electrical products, such as equipment and light control devices, ultimately make lighting a system that is efficient, comfortable, safe, economically beneficial, environmentally friendly, and improves the conditions and quality of people's work and life. Green lighting engineering is designed to save energy and protect the environment. All kinds of lighting places implement the system engineering of é—± lighting. It includes related policies and is a big energy country. The power production is still mainly based on coal burning, and the emissions of 002 and other harmful gases and dusts are severe and complicated. , accounting for about 1 of the total power generation, therefore, effectively saving electricity for lighting, saving resources and energy. Protecting the environment is of great significance. Compared with the advanced countries in the world, China's lighting electrical industry has ranked first in the world, with a total output of more than 6 billion in 2000.
However, the structure of lighting equipment is unreasonable. For example, the thick-tube fluorescent lamps that have been eliminated in foreign countries are still half of the total output of my fluorescent lamps.
The production of foreign lighting appliances is concentrated in several large companies. They have large-scale production facilities and advanced equipment, and continue to develop and produce new commercial energy-saving lighting electrical appliances supply market. The scale of domestic enterprises is small, the level of mechanization and automation of local products is low, the process is backward, the quality of products is unstable, and the production of fake towns and individual enterprises is false. The fake and inferior lighting electrical products are allowed to be marketed, resulting in products in the lighting market, which seriously affects efficient lighting. The reputation of the appliance has hindered the development of green lighting projects.
Since the implementation of the green lighting project in China in 1996, it has been recorded to bear fruit. The quality and production of compact fluorescent lamps have been greatly improved, with an annual output of 300 million pieces, most of which are exported; 8 fluorescent tubes with small diameters are produced in batches, with an annual output of more than 100 million. It will gradually replace the thick tube diameter 2 fluorescent lamp; 15 fluorescent lamps have also been put into mass production in the market, and become the world's major producer of high-pressure sodium lamps, and the products are exported in large quantities. The production of new lighting fixtures and electronic ballasts and power-saving magnetic ballasts has also grown considerably. At present, China's green lighting project is gradually becoming more and more popular. The following focuses on the development of new energy-efficient light sources and lamps.
1 High-efficiency and energy-saving new light source Since 1879, Edison has invented the first incandescent lamp. It has a history of more than 120 years. The development history of light source is the development date of 2000092. The development of incandescent lighting has grown from 10 1 to 30 Jia; The fluorescent lamp developed from Ding 1248 Jia to Ding 868, to the high-efficiency thin tube Kenting 5 fluorescent lamp 104 in the late 1990s, the high-pressure beam lamp developed from 30 Jia to the metal halide lamp and the high-pressure sodium lamp 100 140, and developed into the microwave sulfur in the 1990s. Light 1641.
People strive to bring the light effects of light sources to 200 in the 21st century. Several major new light sources are now introduced.
The L1 energy-saving incandescent lamp and the tungsten halogen lamp change the traditional single-spiral welcoming filament into a longitudinal double-spiral filament, eliminating the filament support, reducing the diameter of the guide wire, reducing the light loss caused by the lamp cap, and the heat conduction loss of the filament. . The filling gas argon gas is changed to helium gas, the bulb volume is reduced by half, the lamp material is saved, the light effect is improved, and the energy-saving incandescent lamp which can be energy-saving 5 10 has entered the market.
Using the principle of halogen tungsten circulation, the incandescent lamp is filled with halogen to make a commercial tungsten lamp, so that the luminous efficacy of the incandescent lamp can be improved from the 15th boundary to the tungsten halogen lamp film or the infrared reflective film can be coated on the inner side with the reflective bowl to improve the halogen halide. Lighting effect. In order to get a better infrared reflection effect.
To improve the high temperature strength of the film layer, a new 202 film system is used instead of the original heart 2 film system, and a double-sided coating film is used instead of the single-sided coating film to improve the reflection effect, and energy saving 10 30. Lifetime 1.5,12 New high-efficiency energy-saving fluorescent lamp Compact fluorescent lamp nickname energy-saving lamp is to bend the discharge circuit of the fluorescent lamp multiple times to shorten the length of the lamp. In order to make the lamp structure more compact and more uniform in light distribution, the spiral compact fluorescent lamp 2 has been successfully developed on the basis of the original 7 type or type, and the luminous efficiency can reach 75100. The volume is small and light, and has broad application prospects. .
After entering the 1980s, fluorescent lamps have been continuously improved in terms of designing process lighting lines. Firstly, it developed a high-efficiency primary color mortar powder to refine the diameter of the fluorescent tube. It also improved the spiral electrode coated with bombardment-resistant electronic powder, and controlled the mercury amalgam; in addition, the argon-filled gas and high-frequency lighting The research and development of the electronic ballast has improved the light efficiency, reduced the loss, and made the tube thinning of the fluorescent lamp succeed and succeed. In addition to the 1 factory, 18 swallowing lamps and small 261.
The 5th type of the 26th and the 12th type were successfully developed, and the light-blocking effect of the 17-blocking light was improved from the 53-type of the 2nd type to the 1st type of the 18-type high-frequency lamp and the luminous efficiency of the 15-type high-frequency lamp 105 was nearly doubled.
The pharyngeal fluorescent lamp has also developed from the single ring state stomach to the double ring type. It uses two different diameter ring tubes to bridge the double ring type and high frequency lighting, which improves the light efficiency and life. 3,1.3 new high pressure gas discharge lamp high voltage Gas discharge lamps include high-pressure mercury lamp metal halide lamp sodium lamp, etc., which have high luminous efficiency and long life. The mercury content is only the fluorescent lamp, and it is used as an energy-saving light source for promotion and application. Recently, the lamp has made progress in developing high-power compactness while developing high-power, high-efficiency, high-color rendering.
High-power metal halide lamps have long arc and short arc =. = High-power high-efficiency metal halide lamp is filled with composite halide in the lamp to increase the vapor pressure of the gold and the material, so that the light efficiency of the lamp is obviously improved. For example, adding strontium to a sodium lamp. The arc center is 蛟, the town enters the new century's green lighting project plus the number of electrons, making the arc thicker, improving the light efficiency, burning 3000 light effect still, up to 73.61 high power high display gold commercial light is 07, etc. Metal-like and heart-like, metal-like, compound combinations, in lamp emission; 1 strong linear spectrum increases the density of rare metals in the entire 1 luminosity range, and uses the continuous molecular spectrum emitted The color rendering performance of the lamp is improved. The color rendering index can reach 90 low-power metal halide lamps. In order to overcome the defects of low luminous efficiency, large color change and unstable photoelectric parameters made by quartz luminous tubes, transparent ceramic deuterium quartz tubes are used to improve the degree of luminous tubes. The ceramic enamel has good chemical stability, and the reaction with the halide is small to make the light color stable. The ceramic tube of the force mouth has high dimensional accuracy, which makes the light color and electrical characteristics of the lamp change. The high-pressure sodium lamp is a high-efficiency discharge lamp. In the early stage of sweating, the light effect reached 1051, and recently, due to the improvement of the light transmittance of the alumina ceramic tube, and the sealing of the most barium pressure, the light efficiency of the lamp reached 139 to prolong the life of the lamp. The method of saturating state and sodium being saturated suppresses the phenomenon of smashing and quenching of the lamp.
In order to improve the performance of metal halide lamps, the electrodeless metal halide lamp was developed from the 1970s, and the gas in the arc tube was excited by the action of an external electromagnetic field. Its discharge form, electrostatic coupling discharge electromagnetic field is particularly suitable for discharge and microwave cavity resonance discharge, 4 is the electromagnetic coupling type electrodeless metal halide lamp that Panasonic Corporation of Japan puts on the market, and is used for illumination of places difficult to be renovated, such as highway tunnel ceiling. 5 is the system structure of the 3.41 microwave sulfur lamp developed in the United States in 1994. The principle is that the microwave energy radiates a continuous and illuminable effective conversion through sulfur production, and the illuminating sphere with a diameter of 28 is filled with sulfur and low Ley gas. The microwave source excitation of 3.4 is called. The energy conversion efficiency of the device is 120 1 boundary, the color rendering index is 86, and the total luminous flux reaches 4 fathers and 41 boundaries. Using light guide technology through the light pipe and the light pottery, the light is transmitted to the place where the light is illuminated, and it can enter the life of the large area lamp up to 3, and can continue to ignite. In 1998, a new low-power sulfur lamp was developed. The power density coupled to the sulfur lamp is reduced from 250 circles to 30 circles, reducing the radiation efficiency of ultraviolet and infrared light up to a lifetime of up to 150001 or even more.
2 High-efficiency energy-saving lamps and lamps and electrical accessories 2.1 Characteristics of high-efficiency and energy-saving lamps The lighting fixtures are assembled from the electrical parts and optical parts of the mechanical parts according to the design requirements of the bright place. In recent years, due to the application of energy-saving light sources and electronic ballasts, the lighting fixtures have been developed in a direction that is light and small, easy to install, and easy to change the direction of light projection. In addition to meeting the lighting-based requirements, and the inch lamps are also called the city of Park Shu Caisheng to suppress glare and mention! Color component requirements. In order to meet these requirements to improve the quality of lighting, the following measures must be taken to use lamps with easy-to-control light-efficient high-gloss paths, electronic ballasts with higher luminous efficiency, reduce ballast power consumption, and control suitable lighting distribution. The light includes the lamp in the luminaire, which does not reduce the light effect; the optical component with less optical loss and easy maintenance and not easy to deteriorate (1) can meet the illumination and can adapt to the installed lighting fixture, as part of the lighting system, the best lighting fixture Adaptation, the design and production of the luminaire must be both practical and decorative to be selected by the user. First of all, the luminaire must have a good design, but also must have high light utilization and scientific light distribution curve. Secondly, the lamps must be shaped and updated quickly to meet the changing needs of different users in different environmental places and different functions.
2.2 The development trend of lighting fixtures and the international, æ›œæž·å˜ é˜Œè¯”éš¹è°Ÿæ•«, 阌诔隹谟敫 ,, light source and equipment supporting applications; promote the application of green lighting products, in the design and production of lamps should be 5 new technology. Reduce 032 emissions, less light pollution, protect the environment; 3 adapt to the needs of human beings into the elderly society, and strive to the Salvage Bureau, installation control is convenient and safe, lighting has a sense of comfort.
2.3 New technology for high-efficiency energy-saving lamps (1) High-frequency mirrors The manufacturing process of old-style mirrors is to prepare a vapor-deposited multi-layer optical reflection film for the evaporation of the substrate. The absorption of light is reduced, and the reflectance of light is increased. The protective layer of the multi-layered reflective film is strong, and silver can be used instead of aluminum as a vapor deposition material to form a reflecting surface. Progress improves the reflectivity, and the cabinet 6 is made of this art, reflective film floodlight.
Frequency Fluorescent Lamps Due to the development of high-frequency fluorescent lamps due to electronic ballast technology, the diameter of the lamps is refined, from 138 to 1 and reduced to ±26 and +16. The length of the lamps is slightly shortened. It has the advantages of small volume, thin film and beautiful appearance, which is easy to install and maintain, saving resources and high efficiency of lamps. For example, the high-frequency spotlight embedded lamp has a thin profile and the small lamp length is short. The length of the lamp is 28, which is suitable for 120-wide standard ceilings. It can be installed directly continuously and can reduce the ceiling and is easy to combine. The efficiency of the mirror grille lamp of high frequency 15 fluorescent lamp can reach 72. Using the 18 type straight tube type fluorescent lamp, the lamp efficiency can be as high as 89. Keeping the original size and the aluminum grille mirror surface, the new high frequency double ring The fluorescent lamp has a thin appearance and beautiful appearance. It can be combined with different ring-type lamps or ring-type lamps and incandescent lamps to become a chandelier-type floor lamp-type ceiling-type indoor decoration lamp. With the wall sweat off or remote control, it can be very square, ± also adjust the light arc weak. Switch the lighting.
Green lighting work is a system engineering. It is China's policy to vigorously promote energy-saving lighting products. In the past few years, China has made some achievements in the production and export of energy-saving lamps, but green lighting products are not just several energy-saving light sources and electronic ballasts. Foreign manufacturers are producing high-efficiency energy-saving light sources and electronic ballasts. It has also introduced a variety of energy-saving products such as high-intensity gas discharge power supplies for electronic control of light control and dimming. At the same time, the development of the all-solid-state light-emitting diode tube, its small size, the brightness has reached the incandescent lamp 201 Jia, and the flat mercury-free fluorescent lamps and microwave sulfur lamps are also listed. These new generation light sources are more energy-efficient, and the matching lamps are more efficient. For this reason, we should strengthen the enterprise at different times to meet the low-cost and eliminate and jointly form a large lighting electrical company, introduce foreign advanced technology and equipment, strengthen the management of the domestic lighting market, crack down on counterfeit and shoddy products, and encourage energy-efficient lighting.
