As everyone's awareness of energy conservation increases, various energy-saving products are very popular. On the other hand, electricity bills are also rising, so it is necessary to install energy-saving lamps in the home. There are many types of energy-saving lamp holders on the market. What do you know? I believe that many people should not know how to buy energy-saving lamp holders. Xiaobian has already summarized the types of energy-saving lamp holders and the purchase tips of energy-saving lamps. Let's take a look!
First, what kinds of energy-saving lamp heads
1, self-ballasted fluorescent lamps
The luminous efficiency is above 60lm/W, which is 4 times higher than that of ordinary incandescent light, and the service life is over 8000h.
2, double-ended fluorescent lamp e27 lamp holder
(Thin pipe diameter) Compared with double-ended fluorescent lamps (thick pipe diameter), the service life is extended by 20%, the luminous efficiency is increased to 22%, the direct energy saving is 10%, and the service life can reach 10000h or more.
3, high pressure sodium lamp
The luminous efficacy is 90-100lm/W, which is 2 times and 7 times higher than that of mercury and incandescent lamps, respectively. The color rendering index is 60. The ultraviolet component is small, it is not rusted, and the object to be illuminated does not fade. The color temperature is only 2100K.
4, electronic ballast
40W, 20W electronic ballast and magnetic ballast save 5W, 3W respectively, the household with a 20W electronic ballast annual power saving 20kwh, a 40W electronic ballast annual energy saving 60 Kilowatt hours, in addition to the voltage as low as 130V can also illuminate.
5, metal halide lamp
The lamp head is a new light source with a color rendering index of more than 80, a luminous efficacy of 75 lm/W or more, and a color temperature of 6000K. The advantages are long life, high luminous efficiency, good color rendering and obvious power saving effect. It is the fourth generation light source in the world today.
Second, the purchase of energy-saving lamps
1, look at the packaging and trademark
The state mandates that the energy-saving lamp products be marked with the following contents on the outer packaging: source mark, rated voltage, voltage range, rated power, and rated frequency. On the lamp, on the package, or in the instruction manual, the current on the lamp and other supplementary instructions related to safe use are generally mentioned. Generally speaking, the quality of the product of the high-quality product is good, the font is clear and not easy to fall off, and it is wiped with a soft damp cloth. The mark is clear and identifiable and difficult to wipe off. There are trademarks and related certification marks of the manufacturer. The printing quality of the fake and inferior products is poor, the font is fuzzy and easy to erase, and there is no trademark of the manufacturer and related certification marks.
2, look at the quality of plastic parts
The plastic casing of the energy-saving lamp must be made of flame-retardant engineering plastic. The advantages are: heat-resistant flame retardant, good electrical insulation, high hardness, good rigidity, resistance to cracking, easy printing, whitening and no discoloration. The disadvantage is that the cost is slightly more expensive. Ordinary plastics are forbidden to be used in the production of energy-saving lamps, while counterfeit products use medium and low-grade plastics. Their heat resistance and flame retardancy do not meet the standard requirements. They are brittle and easy to crack, easy to yellow and fade, and there are potential safety hazards.
3, look at the appearance of the tube
Comparing multiple tubes together, the shape and size consistency of the tubes are mostly mass-produced products, the quality is guaranteed, and the shell can not be cracked or loosened, and there should be no traces of the seals. During the installation and disassembly process, the lamp cap should not be loose or smashed.
4, look at the tube phosphor
The high-quality product adopts rare earth trichromatic phosphor coating, which has high luminous efficiency, high color rendering index, good thermal stability, light decay caused by 185nm ultraviolet light, and long life. A high-quality energy-saving lamp is equivalent to 3 to 8 inferior energy-saving lamps. The use time, but the price is high, the counterfeit product adopts the mixed powder coating of halogen powder or rare earth trichromatic phosphor mixed with halogen powder, the luminous efficiency is lower than the rare earth trichromatic phosphor by 30%, the color rendering index is low, and the thermal stability is poor. The light decay is severe and the life is short, which is especially unsuitable for use in thin tube fluorescent lamps.
5, look at the quality of electronic ballasts
The high-quality products have been produced by reasonable circuit design and selected high-quality electronic components. The heat generated during operation is small, the power factor is high, the filter components are installed, the harmonic content is low, and there is basically no electromagnetic interference to the electrical equipment. The designed working frequency is high. Achieving the level of non-frequency flash source, protecting consumers' vision and physical health. In order to save production costs, counterfeit products are assembled and produced through outsourced inferior electronic ballasts. The quality cannot be guaranteed, the failure rate is high, and serious fires may occur. And other security issues.
The above is what the energy-saving lamp heads shared by you in the small-package network Xiaobian, the purchase tips of energy-saving lamps, I hope to help you.
