Due to the integration of energy-saving lamps and environmental protection, it is now more and more popular and favored, but it is also because the demand for energy-saving lamps is increasing, and the market for energy conservation is becoming more and more mixed. The high-quality lamps are more and more difficult. If the energy-saving lamps bought are often replaced due to quality problems, it will not only save energy, but will also waste resources. Therefore, consumers must pay attention to some purchasing techniques when purchasing energy-saving lamps. Today Xiaobian teaches you how to buy energy-saving light bulbs .
First, the introduction of spiral energy-saving light bulbs
The spiral energy-saving lamp is also called a power-saving light bulb. It has a semi-spiral energy-saving lamp and a full-spiral energy-saving lamp. It belongs to a kind of energy-saving lamp. Generally, the energy-saving lamp inductive ballast is used to drive the fluorescent tube to emit light. The color temperature is between 2500K and 6800K. The color temperature is 2700K. We usually call it yellow light. The color temperature is 4200K, which is usually called warm light. The color temperature is 6400K. We call it white light.
Spiral energy saving lamp structure
Lamp cap: Usually used E27, B22, E40 (used by high power lamps).
Plastic parts: PP (halogen powder low-grade lamps), PC (mixed powder mid-range lamps), and PBT (flame-resistant materials for three-color high-end lamps) are commonly used in the market.
Circuit board: 94V0 flame retardant sheet is generally used.
Spiral tube: full spiral tube, half spiral tube.
Buy common sense
Seven things you must know to buy an energy-saving lamp:
1. Many consumers purchase energy-saving lamps with reference to the power of tungsten bulbs that have always been used. Most manufacturers will list the power of the product itself and the power of the tungsten light bulb with similar luminosity on the package. For example: the package has a "20W → 85W" mark, which generally means that the actual power of the lamp is 20W, claiming to emit a luminosity similar to that of an 80W tungsten wire bulb.
2. Some products have energy efficiency labels on the packaging. The product meets the safety specifications, the light is ready to reach a certain level, and the average life expectancy exceeds 8000 hours before the energy efficiency label can be issued.
3, some energy-saving lamps are available in white and yellow light colors. The average person feels that the white light is colder and the yellow light is warmer. To compare the differences between the different colors, you can go to the showroom to appreciate. Users can choose the color of the light that matches the furnishings of the home according to their personal preferences.
4, some stores provide lamp holders to test the lamp for consumers, try it before payment, to ensure that its operation is normal, observe its brightness.
5, when purchasing energy-saving lamps, we must also consider the technical parameters of the electronic ballast, such as harmonic content, power factor, whether or not equipped with filter components and other indicators. Especially in some large-area, large-volume use of energy-saving lamps, we must use low-harmonic, high-power factor, energy-saving lamps with filter components, and install as many power switches as possible to avoid simultaneous switching of large number of energy-saving lamps. The high voltage pulse of the power grid impacts and causes damage.
6, the plastic shell of the whole lamp, should choose high temperature resistant flame retardant PBT plastic shell.
7. Pay attention to observe whether the lamp is affected by the uneven illumination of the phosphor coating after the power is turned on.
I believe that everyone has a certain understanding of spiral energy-saving lamps, and know some of the purchase knowledge of spiral energy-saving lamps, we will not worry about the choice of problems, thus saving more time and effort.
Second, how to choose energy-saving light bulbs
First of all, we must understand the brand of energy-saving lamps. In the tests of the two standards of safety and performance conducted by the state in 1998 and 1999, the qualified domestic brands were only Guangdong “Hua Xingâ€, Nanjing “Electricianâ€, Beijing “North Starâ€, “Hua Mingâ€, Weihai “Beiyangâ€, etc.; Secondly, we must purchase products with the promise of “Three Guaranteesâ€; third, we must pay attention to whether the product identification is complete. Regular products generally have registered trademarks, factory names, factory addresses, contact numbers, etc. Fourth, do not buy too low prices. The product. In general, domestic energy-saving lamps with a life span of 5,000 hours to 3,000 hours are between 15 and 20 yuan. General energy-saving lamps such as 9 watts, 13 watts, 2U (4 tubes), spiral energy-saving lamps, the price is about 18 yuan - 20 yuan, 15 watts - 28 watts of 3U (6 tubes) energy-saving lamps retail price of about 30 yuan.
Nowadays, the energy-saving lamps on the market are mostly compact, and the sockets are completely unified with the incandescent lamps, and can be directly used without changing the original lines. Generally, there are H-shaped, U-shaped, etc., which can adapt to different assembly requirements, and some also cover a transparent or frosted outer cover on the outside of the lamp tube for protecting the lamp and making the light uniform. 5-20W is suitable for ordinary home lighting.
How to choose a method? Here are some "tricks" for reference when purchasing:
1. Choose those with higher brand awareness: such as PHLIPS, OSRAM, Zhejiang Sunshine, etc. Should choose the beautiful packaging, beautiful appearance, the manufacturer's address is complete and the technical description is complete.
2, look at the startup performance. If the merchant has the best voltage regulator, in the power-off state, first adjust the voltage regulator to the minimum starting voltage (such as 150v) output, install a cold light, the power supply will start flashing less when the power is turned on, the root of the lamp No red light, one-time ignitor is best.
3. Look at the working status. After the start is smooth, adjust the regulator to the maximum (such as 250v), work under high pressure for more than 5 minutes, let it heat up quickly to see if there is flicker, and smell or not smell.
4. Look at the performance after work. Finally, don't forget to compare the temperature of the lamp body. The lower the temperature, the better. In addition, after the test, there will be a black mark on the root of the lamp. The longer and darker the black segment, the lower the lamp life is.
5. Appearance inspection. The plastic shell of the lamp must be selected from flame-retardant engineering plastics. The surface is smooth and shiny, and the shape and size of the tube are consistent. Of course, there must be no cracks, looseness, and traces between the interfaces.
Third, what should be paid attention to when using energy-saving light bulbs
To play the benefits of energy-saving lamps, we must first ensure the longevity of the lamps, we must pay attention to the following points:
1. Do not use in high temperature or high humidity environment. Since the current energy-saving lamps are mostly compact, the internal heat-dissipating conditions are poor, and they are in a working state under high-frequency and high-voltage conditions. Therefore, under high temperature and high humidity, it is easy to cause denaturation of magnetic materials, discharge between lines, and secondary strike of transistors. Wear and so on. Energy-saving lamps should not be used in bathrooms and kitchens.
2. When installing or disassembling the energy-saving lamps, be sure not to hold the lamp tube parts to prevent them from being broken. Pay attention to the self-removal of this kind of lamp. First, the upper and lower parts of the lamp body are mostly bayonet rather than threaded. The second is the lamp that starts the fault. After disconnecting the external power supply, it is still possible to leave a high voltage of more than 300 volts in some parts. Be sure to pay attention to safety.
3. Do not install this kind of lamp in the lamp holder with dimming device to avoid damage.
4. When the weather is too cold or the voltage is too low, the lamp will start to be bad. Don't let the lamp always be in the high current starting state of the lamp red. It can be turned off and then turned on again. Usually the second start can work. .
Through the above introduction, I believe that everyone has a certain understanding, if the heart is moving, then act now, try it, do the energy-saving lamps purchased to save electricity and save money, why not?
