Which is better between energy-saving lamps and ordinary light bulbs:
Energy-saving lamps are what we call energy-saving light bulbs in our daily life. Ordinary incandescent light bulbs are not energy-saving enough, but the price is still relatively cheap. Which of the two is better? Let’s first take a look at the comparison of the two:
1. Energy saving comparison:
Generally speaking, in the case of the same wattage, energy-saving lamps save 80% energy than ordinary bulbs, and energy-saving lamps consume 57% less electricity than ordinary bulbs. A 5-watt energy-saving lamp is about equal to a 25-watt ordinary bulb. Brightness, 7 watts of energy-saving lamps are about equal to the brightness of 40 watts of ordinary light bulbs, and 9 watts of energy-saving lamps are about equal to the brightness of 60 watts of ordinary light bulbs. It can be seen that energy-saving lamps are more energy-efficient than ordinary white woven lamps.
2. Principle comparison:
Energy-saving lamps use the principle of gas discharge to operate, that is, self-ballasted fluorescent lamps. The heat radiation of energy-saving lamps is only 20%, while ordinary light bulbs are the heat energy generated by the current passing through the filament. Above Celsius, the higher the temperature of the filament, the brighter the light emitted. When ordinary light bulbs emit light, a large amount of electrical energy is converted into heat energy, and a very small part is converted into useful light energy. generation of radiation.
3. Health comparison:
Energy-saving lamps can effectively remove formaldehyde and dirt, and the active oxygen released at the same time can absorb and kill various viruses and bacteria such as Escherichia coli. 6 times that of ordinary incandescent lamps.
4. Life comparison:
The life of ordinary fluorescent lamps mainly depends on the tungsten wire. The faster the tungsten sublimates, the shorter the service life of ordinary fluorescent lamps, while the energy-saving lamps rely on gas and luminescent materials coated on the tube wall to work, and the luminous efficiency is higher and more durable than tungsten. Therefore, the lifespan of energy-saving lamps is longer than that of ordinary bulbs. The lifespan of ordinary bulbs is usually 2500-3500 hours, and the national standard lifespan is 1000 hours, while energy-saving lamps can be as high as 50,000 hours.

The above is a brief introduction about the detailed comparison of energy-saving lamps and ordinary light bulbs. I believe that after the above introduction, everyone will have a further understanding of energy-saving lamps and ordinary lighting lamps. Natural energy-saving lamps are much better than ordinary lighting lamps. The current market There are many types of energy-saving lamps on the market. What are the common types and purchasing skills of energy-saving lamps at home? Let's take a look at the following introduction:
Common types and purchasing skills of home energy-saving lamps:
1. Common types of home energy-saving lamps:
1. High voltage nano light:
The efficiency is 90-100 lumens/watt, which is 2 times and 7 times higher than that of mercury lamps and incandescent lamps, respectively, with a color rendering index of 60, less ultraviolet components, no insects, no fading of illuminated objects, and a color temperature of only 2100K.
2. Metal halide lamps:
A new light source with a color rendering index of more than 80, a luminous efficiency of more than 75 lumens/watt, and a color temperature of 6000K. It has the advantages of long life, high light efficiency, good color rendering, and obvious power saving effect.
3. Electronic ballast:
Compared with 40W and 20W electronic ballasts and magnetic ballasts, the power consumption can be saved by 5W and 3W respectively. A 20W electronic ballast for households can save 20kWh of electricity annually, and a 40W one can save electricity. Electronic ballasts save 60 degrees of electricity annually.
4. Self-ballasted fluorescent lamps:
The light effect is above 60 lumens/watt, which is 4 times higher than that of ordinary incandescent light, and the life span is more than 8000 hours.
5. Double-ended fluorescent lamp (thin tube diameter):
Compared with double-ended fluorescent lamps (thick tube diameter), the lifespan is extended by 20%, the light efficiency is increased by 22%, the energy saving is 10%, and the lifespan can reach more than 10,000 hours.
Second, home energy-saving lamps purchasing skills:
1. Look at the packaging and trademarks:
The state mandates that energy-saving lamp products be marked with the following contents on the outer packaging: source mark, rated voltage, voltage range, rated power, rated frequency, on the lamp, on the packaging, or on the instruction manual to mark the current of the lamp, and other related information. Supplementary instructions related to safe use. Generally speaking, the trademarks of high-quality products have good printing quality, clear fonts, and are not easy to fall off. When wiped with a soft damp cloth, the marks are clear and legible, and they are not easy to erase. The printing quality of the product is poor, the font is fuzzy, easy to erase, and there is no manufacturer's trademark and related certification marks.
2. Look at the quality of plastic parts:
The plastic shell of the energy-saving lamp must be made of flame retardant engineering plastics. The advantages are: heat resistance and flame retardant, good electrical insulation, high hardness, good rigidity, crack resistance, easy printing, white and no discoloration; disadvantages: slightly expensive cost , Ordinary plastics are forbidden to be used in the production of energy-saving lamps, and the fake and inferior products use medium and low-grade plastics, whose heat resistance and flame retardancy do not meet the standard requirements, and are brittle and easy to crack, easy to yellow and fade, and there are potential safety hazards.
3. Look at the appearance of the lamp:
Comparing multiple lamps together, the lamps with better shape and size consistency are mostly mass-produced products, the quality is guaranteed, and the shell should not have cracks or loosening, and there should be no signs of being pryed at the seal. , In the process of installation and disassembly, the lamp head should not be loose or tilted.
4. Look at the fluorescent powder of the lamp:
High-quality products are coated with rare earth tri-color phosphors, which have high luminous efficiency, high color rendering index, good thermal stability, resistance to light decay caused by 185nm ultraviolet rays, and long life. One high-quality energy-saving lamp is equivalent to 3 to 8 low-quality energy-saving lamps. The lamp can be used for a long time, but the price is high. The fake and inferior products are coated with halogen powder or rare earth three-primary phosphor powder mixed with halogen powder. Its luminous efficiency is 30% lower than that of rare earth three-primary phosphor powder, with low color rendering index and poor thermal stability. , serious light decay, short life, especially not suitable for use in thin tube fluorescent lamps.
5. Look at the quality of the electronic ballast:
High-quality products are produced through reasonable circuit design and high-quality electronic components. They have low heat generation, high power factor, filter components, low harmonic content, and basically no electromagnetic interference to electrical equipment. The designed working frequency is high, and the basic Reaching the level of non-frequency flash source, protecting people's eyesight and physical health. In order to save production costs, fake and inferior products are assembled and produced by purchasing inferior electronic ballasts. The quality cannot be guaranteed, the failure rate is high, and serious fires may be caused. security issues.
