at the following description: Recognizing the energy-saving lamps for general lighting with self-ballasted fluorescent lamp is a single-ended fluorescent tubes and electronic ballasts together constitute a new type of compact electric light source (commonly known as energy-saving lamps), energy-saving lamps are small, provincial electricity, light, high efficiency, light, soft, etc., are therefore more and more energy-efficient lighting products to the general consumer acceptance and use. Energy-saving lamps on the market today are mostly compact, incandescent lamp socket with the complete reunification. The general energy-saving lamps is based on tube shape to carry out Category: English alphabet pictographic naming of places, for example: H-shaped, U-shaped, D-shaped, spiral-shaped and so on, a different shape to adapt to different assembly requirements. Energy-saving lamps, compared with ordinary light bulbs or tubes, first with a light-emitting efficiency, energy-saving advantages of good effect. To H-type energy-saving lamps, for example, H-1 7W energy-saving lamps 40W luminous flux and the very ordinary incandescent light. Can be seen that general lighting with self-ballasted fluorescent lamp light effect is the incandescent lamp 6 ~ 7 times more than the normal straight tubular fluorescent lamps higher than 30%. In addition, energy-saving fluorescent lamp ballasts, compared with the inductive type, in addition to energy-efficient, small size, light weight, etc., but also has: 1, no flicker, no noise, good for your health. 2, low-voltage start-up performance is good. Fluorescent Lamp Ballast, when the voltage drops below 180V, it is difficult to start, while the electronic ballast energy-saving lamp in the supply voltage 130V ~ 250V range. After about 2 seconds or so, you can quickly ignite a one-time starter. 3, pairs of low-quality network adaptability. 4, long life. Inductor rated life of fluorescent lamps is 2000 hours, while the electronic energy-saving lamps rated life of 3000 ~ 5000 hours, some as high as 8000 ~ 10000 hours. The basic parameters of energy-saving lamps directly affects the quality of its products, its basic parameters of the main electrical parameters and optical parameters are divided into two categories, the following a few basic technical parameters from the energy-saving lamps look at the quality of a specific analysis. 1. Power of the size of the reflected power and brightness of the lamp Size: 10 square meters following a small area lighting 9 ~ 13W more appropriate, these types of power energy-saving lamps in the process is more mature, the relative price of relatively cheap and cost-effective high ; more than 10 square meters room lighting can choose more than 15W energy-saving lamps, high-power energy-saving lamps prices are relatively expensive. It should be noted that some companies tend to increase the price into the high-power low-power beacon light, to deceive the consumer, directly damaging the interests of consumers. 2. Power Factor: The experiment proved that the lower the power factor, energy efficiency worse, tube ends prematurely, the more likely black, corresponding to shorten life. Good quality energy-saving lamps, power factor can reach 0.9 or more, brand name manufacturers to produce large power energy-saving lamps with power factor correction technology, its power factor even higher, almost as a pure resistance. 3. The total current harmonic should normally be 50% or less, this value is smaller, the smaller the harmonic currents, arising from the use of the less high-frequency interference. 4. Luminous flux and luminous flux maintenance ratio: the former reflects the lamp light-emitting efficiency is high or low value the bigger the better, which indicated that the speed of lamp aging, generally after 2000 hours of luminous flux maintenance rate should be above 80%. 5. Color rendering index should normally be between 63 ~ 85, this value is greater that the closer the spectral lamp issue of natural light, for vision better, the human eye seems to have been more comfortable. There are many other energy-saving lamps can assess the quality of technical parameters, such as crest factor, start-up time, color, etc. tolerance. So, ordinary consumers on how to identify energy-saving lamps in the quality of the bad? Here's from a few simple-pronged approach to describe how to choose good quality energy-saving lighting products: 1. Should be selected by the safety certification of products, such as Philips (PHILIPS), Germany Aasland (OSRAM), General ( GE), Weihai Beiyang, sunlight Group, Far East, the electricity giant's products, its quality can be guaranteed. 2. From the packaging point of view, should look fine, printing beautiful, name and address, telephone and package insert, etc. are well documented. Check the appearance of light, in the light of the plastic pieces to be clearly labeled parts of the source of light mark (which may be a trademark or manufacturer's name), rated voltage and voltage range, rated power, rated frequency; the glass tube should be smooth , no bubble; the phosphor coating inside the lamp should be fine, no particles, uniformly white; lamp and the lamp should be vertical state, should not be tilted; tube and plastic parts should be firmly connected between the and should not be loose; There should be shaking his hand the whole ring lights. 3. Energy-saving lamp plastic cover must be made flame retardant engineering plastics, ordinary plastic banned the production of energy-saving lamps. In addition, from an overall point of view, and more than can be put together to compare lights, fluorescent tubes and consistency in good shape and size are mostly mass-produced products, quality is guaranteed. And the shell can not have cracks, loose, sealing Department should not have broken. 4. From the start-up performance perspective. If the voltage regulator with the time of purchase the best power-off state voltage regulator should first transferred to 150V (or press statement marked the Moldlowest turn-on voltage), fitted with an energy-saving lamps, hand and body away from the lights, then After the power should be able to pass a fire. Because there are two characteristics of energy-saving lamps to start: First, the higher the temperature, start the more likely; Second, under the effect of induction in the human body easy to start. It is worth mentioning is that many energy-saving lamps which opened a bright, which is also unfavorable to the lamp life, energy-saving lamps should be equipped with filament preheating in its internal circuit, there should be about 0.4 seconds startup delay time. 5. Look at anti-jamming case. Electromagnetic compatibility is the performance of household electrical appliances must have. Users to buy, we should examine whether there is on the box through the national symbol of electromagnetic compatibility test. 6. Energy-saving lamps in the normal working state, its temperature rises to be very low, otherwise, energy-saving lamp life will be short. Meanwhile, energy-saving Moldlamps lit, the lamp at both ends of black, red or flashing the filament, are stating that the energy-saving lamps of questionable quality. 7. Energy-saving lamps in use before the first should look at the instructions for use, the current domestic energy-saving lamps are not available for most of the dimming circuit, therefore, which warnings should be indicated in the use statement. In addition, energy-saving lamps contain ballast circuit, it is best not to use light sources in the need to frequently switch places. 8. Buy energy-saving lamps, we must not only consider the price, regardless of quality. Some enterprises are based on customer psychology, producing multiple grades of products, how much money your product will give you what grade of light, if the blind pursuit of low prices, it is very possible to buy substandard products at home.
