Nowadays, power is tight, and “power saving†has become the most fashionable thing this summer. Energy-saving lamps have become the most fashionable light source.
The surface of the energy-saving lamp saves electricity. The price of ordinary light bulbs is between 1.5 yuan and 3 yuan, and the energy-saving lamps are usually more than 10 yuan. If the number of purchases is large (for example, you need 8 lanterns for a living room). Energy-saving lamps), the amount of one-time expenditure is indeed a bit large. But if you calculate it, the energy-saving lamps will save money. Mr. Zhang, who manages the wholesale of lamps, told reporters: “In general, the power consumption of energy-saving lamps is only about 20% of that of ordinary incandescent bulbs. For example, a room with 60W ordinary light source is illuminated. If you turn on the lights for five hours every day, about It consumes one kilowatt hour every three days, and if energy-saving lamps are used, it can save about 3.2 yuan per month. At present, household energy-saving lamps are generally between 5W and 13W, which is much lower than ordinary 30W and 45W incandescent lamps. In addition, energy-saving lamps can generally be "guaranteed for one year", that is, quality problems can be replaced within one year, while incandescent bulbs do not have this advantage. In addition, the energy-saving lamps have the advantages of better "reduction rate", more natural (close to sunlight), and higher eye comfort.
Energy-saving lamps are good or bad, and the price of energy-saving lamps on the market ranges from a few yuan to tens of yuan. This is the difference between good and bad. Judging the quality of an energy-saving lamp, professional advice, can be considered from the following aspects.
First, security. To judge whether an energy-saving lamp is safe, it is necessary to carefully observe 6 aspects in the hand: whether the combination of the lamp head (iron or copper, aluminum) and the plastic part is tight; whether the combination of the lamp tube and the plastic part of the lower case is firm; the upper shell plastic part and Whether the clamping position of the lower shell plastic parts is tight, whether it can be detached at high temperature; whether the outer plastic parts are made of flame retardant and high temperature resistant (180 ° C) materials; whether the skeleton and circuit board in the electronic ballast circuit are made of flame retardant materials;
Generally, good energy-saving lamps and products use PBT flame-retardant and high-temperature resistant materials. ABS plastics are generally used. The plastics begin to deform at a normal temperature of about 90 °C, and the flame retardancy is not good, which is easy to cause fire.
Second, the service life. The average life expectancy of good energy-saving lamps is more than 5000 hours. The average life of poor products is about 1000 hours. Some even burn out in 20 minutes, and the life is not as good as one candle.
An energy-saving lamp was dissected and found to consist of a tube and an electronic ballast. The life of a lamp has a very strong relationship with raw materials, manufacturing processes, manufacturing equipment, and quality control and assurance systems.
An ordinary type of energy-saving lamp electronic ballast consists of about 30 components. If one of the components is damaged, the energy-saving lamp cannot be lit. If the components of an electronic ballast are very good, if the parameters are suitable. If the distribution is not good, the life of the electronic ballast will not be long. If the above two items are well done, if the process control is not good and the quality management is not well controlled, even if the above work is done well, it will be in vain. Therefore, don't look at the small lamp, which process on the production line is sloppy.
Third, luminous flux, light decay and light efficiency. This is a three indicator that reflects whether an energy-saving lamp product has energy-saving effects.
A good energy-saving lamp, the lamp adopts high-efficiency three-primary phosphor, and the water-powder coating process is better. The luminous efficiency is above 50Lm (lumen) per watt, even above 60Lm (lumen). The light decay of 2000 hours is about 10%~20%.
A poor quality energy-saving lamp uses a halogen powder tube. Since the halogen powder tube adopts the phosphorophosphoric acid phosphor powder and adopts the organic powder coating process, since the corresponding manufacturer's exhaust process, raw materials, equipment and technical means are backward, such a lamp has a short life span, and from some national standard measurement institutions According to the random inspection, the initial luminous flux of a 9W halogen powder lamp is only 248Lm, and the light decay of 100 hours is as high as 23%. According to the national standard, the lumen maintenance rate of the compact energy-saving lamp for 2000 hours cannot be lower than 78%, and one The high-quality energy-saving lamp has an initial luminous flux of 560Lm and maintains a luminous flux of 431Lm to 5000 hours.
Fourth, color tolerance, color rendering index, and color temperature consistency of the entire batch. This is an important indicator for reflecting the light parameters of energy-saving lamps. From this we can see the purity of the manufacturer's three primary color phosphors. The national standard stipulates that the color rendering index of the energy-saving lamp of 6400K color temperature of three primary color fluorescent lamps should be greater than 78, and the color tolerance should be less than 6. The color rendering index of energy-saving lamps with color temperature of 2700K is greater than 80, and the color tolerance is less than 6. Good energy-saving lamps can reach this level. The poor energy-saving lamps are poor in color and the process is inconsistent because of the poor phosphor used.
5, the color rendering index is less than 50, which is difficult for some commercial lighting to meet the requirements, especially in some large-scale energy-saving lamps, because of its low color rendering index, color temperature consistency is poor, looks dazzling .
Fifth, the raw materials and manufacturing process of electronic ballasts. A good energy-saving lamp, materials, processes, equipment and quality control methods are very good.
How to save energy and save energy-saving lamps, you should pay attention to the above technical links, if you do not understand the professional problems, you can also go to a guaranteed shopping mall.
Choose energy-saving lamps, choose the best quality as possible, in order to achieve "energy saving and saving money." Therefore, to buy energy-saving lamps to choose a well-known brand.
When purchasing, please confirm that the product packaging is complete and the logo is complete. The life of the energy-saving lamp, the color rendering, and the correct installation position are usually described on the outer package. After opening the package, there should be some necessary signs on the energy-saving lamps, including: power supply voltage, frequency, rated power, manufacturer's name and trademark.
When checking the quality of the selected energy-saving lamps, look at whether the surface is smooth, whether the powder is even, whether there is blackening, if not, do not; in addition, you can shake the energy-saving lamps up and down, good energy-saving lamps, the interior should be broken The sound of slag is moving. Then, it can be repeatedly installed and unscrewed several times on one lamp holder, and the lamp cap should not loosen and fall off. Finally, look at the center of the lamp joint, and the center solder joints of the goods are even and shiny.
Precautions for the use of energy-saving lamps Energy-saving lamps have U-shape, spiral shape, petal shape, etc., and the power ranges from 3 watts to 40 watts. The prices of energy-saving lamps of different models, different specifications and different origins vary greatly.
In the home, energy-saving lamps can usually be installed in lamps such as downlights, chandeliers, and ceiling lamps. Energy-saving lamps are generally not suitable for use in high temperature and high humidity environments. Therefore, energy-saving lamps should be avoided in bathrooms and kitchens.
There are three points to note when using energy-saving lamps:
First, the lamp with the dimmer switch cannot be used;
Second, the power supply voltage should be stable and should match the nominal rated voltage of the lamp;
Third, when replacing the energy-saving lamp, avoid holding the lamp and pay attention to replace it after power off.
Advant Master is a widely installed and actively supported ABB DCS. It is used by many customers that plan to stay on the platform for several years to come. A majority of customers have enhanced user experience by adding the System 800xA HMI to their Advant systems controllers and I/Os.
Released in 1992, Advant Master DCS was the result of the development of a common hardware and software platform for evolving the ABB Master and Taylor MOD 300 systems.
Advant Master DCS introduced two high capacity controllers, AC450 and AC410, and the S100 rack mounted I/O featuring an improved redundancy scheme, along with a state of the art operator interface, based on UNIX workstations. In 1996 the S800 remote I/O was launched, providing modular flexibility with redundant communication and a 1ms time stamp.
The predecessor to Advant Master DCS, ABB Master, was introduced in 1984 based on MasterPiece 200 controllers with the rack mounted S100 I/O along with the MasterView 800 operator interface with high end Tesselator Display system, further adding remote S400 I/O in 1988. Remote EX S800 I/O and Profibus DP support for connection to third party sub systems was released in the late 1990s.
