Energy-saving lamps and ordinary light bulbs which is good
There are many home lighting products on the market, and the characteristics of lighting lamps with different light sources are also different. Energy-saving lamps are a common indoor lighting product. Compared with traditional ordinary light bulbs, which one is energy-saving lamp and ordinary light bulb? Okay? What are the common types of energy-saving lamps in the home and their purchasing skills? Let's follow the editor of Benwei lighting to get to know it, I hope it will be helpful to everyone.
Energy-saving lamps
Which is better, energy-saving lamp or ordinary light bulb:
Energy-saving lamps are the energy-saving bulbs we call in our daily lives. Ordinary incandescent bulbs are not energy-efficient, but the price is still relatively cheap. Which is better, let's take a look at the following 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 light bulbs, and energy-saving lamps consume 57% less power than ordinary light bulbs. A 5 watt energy-saving light is approximately equal to a 25 watt ordinary light bulb Brightness, a 7-watt energy-saving light is approximately equal to the brightness of a 40-watt ordinary light bulb, and a 9-watt energy-saving lamp is approximately equal to the brightness of a 60-watt ordinary light bulb. 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 heat generated when electric current passes through the filament. The filament continuously gathers heat to make the filament temperature reach 2000 Above degrees Celsius, the higher the filament temperature, the brighter the light emitted. When ordinary bulbs emit light, a large amount of electric energy is converted into heat energy, and a very small part of it is converted into useful light energy. Due to the low conversion efficiency of electricity to light, it first generates heat and then emits light, so infrared The 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 many viruses and bacteria such as E. coli. Energy-saving lamps can also change the air quality of the room. It has advanced manufacturing technology, high efficiency and long service life. 6 times that of ordinary incandescent lamps.
4. Lifespan comparison:
The lifespan of ordinary fluorescent lamps mainly depends on the tungsten wire. The faster tungsten sublimates, the shorter the lifespan of ordinary fluorescent lamps. Energy-saving lamps rely on gas and the luminescent material coated on the tube wall to work, and their luminous efficiency is higher and more durable than tungsten. Therefore, the lifespan of energy-saving lamps is longer than that of ordinary light bulbs. Ordinary light bulbs usually have a life span of 2500-3500 hours, and the national standard life span is 1000 hours, while energy-saving lamps can reach as high as 50,000 hours.
Energy-saving lamps
The above is a brief introduction about the detailed comparison between energy-saving lamps and ordinary light bulbs. I believe that after the above introduction, everyone will have a better 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 Internet. What are the common types and purchasing skills of household energy-saving lamps? Let's take a look at the following introduction:
Common types of home energy-saving lamps and purchasing skills:
1. Common types of home energy-saving lamps:
1. High-voltage sodium lighting:
The efficiency is 90-100 lumens/watt, which is 2 times and 7 times higher than the light efficiency of mercury lamps and incandescent lamps, respectively. The color rendering index is 60, the ultraviolet component is less, it does not attract insects, and the illuminated object does not fade. The color temperature is only 2100K.
2. Metal halide lamp:
A new light source with a color rendering index of 80 or more, a luminous efficiency of 75 lumens/watt or more, a color temperature of 6000K, long life, high luminous efficiency, good color rendering, and obvious power-saving effects. It is the fourth-generation light source in the world today.
3. Electronic ballast:
Compared with inductive ballasts, 40 watt and 20 watt electronic ballasts can save 5 watts and 3 watts respectively in power consumption. A 20 watt electronic ballast can save 20 kWh per year for household use, and one 40 watt. The electronic ballast saves 60 degrees of electricity per year.
4. Self-ballasted fluorescent lamp:
The luminous efficiency is above 60 lumens/watt, which is 4 times higher than that of ordinary incandescent lamps, and the life span is more than 8000 hours.
5. Double-ended fluorescent lamp (thin tube diameter):
Compared with the double-capped fluorescent lamp (thick tube diameter), the life span is extended by 20%, the luminous efficiency is increased by 22%, the energy saving is 10%, and the life span can reach more than 10,000 hours.
2. Buying tips for home energy-saving lamps:
1. Look at the packaging and trademarks:
The state mandates that energy-saving lamp products be marked with the following content on the outer packaging: source mark, rated voltage, voltage range, rated power, rated frequency, on the lamp, package, or on the instruction manual to mark the current of the lamp, and other related information. Supplementary instructions for safe use. Generally speaking, the trademarks of high-quality products have good printing quality, clear fonts, and are not easy to fall off. Wipe with a soft damp cloth, the signs are clear and identifiable, not easy to erase, there are manufacturer’s trademarks and related certification signs, fake and inferior Product printing quality is poor, font is fuzzy, easy to erase, no manufacturer's trademark and related certification marks.
2. Look at the quality of plastic parts:
The plastic shell of energy-saving lamps must be made of flame-retardant engineering plastics. The advantages are: heat-resistant and flame-retardant, good electrical insulation, high hardness, good rigidity, crack resistance, easy to print, white and no color; the disadvantage is: the cost is slightly more expensive , Ordinary plastics are forbidden to be used in the production of energy-saving lamps, while low- and medium-grade plastics are used for fake and inferior products. Their heat resistance and flame retardancy do not meet the standard requirements. They are brittle and easy to crack, yellow and fade, and pose safety risks.
3. Look at the appearance of the lamp:
Compare multiple tubes together. Most of the tubes with better consistency in shape and size are mass-produced products. The quality is guaranteed. At the same time, there should be no cracks or looseness in the shell, and there should be no traces of prying on the seal. , In the process of installation and disassembly, the lamp cap should not be loose or tilted.
4. Look at the fluorescent powder of the lamp:
High-quality products use rare earth three-color phosphor coating. It has high luminous efficiency, high color rendering index, good thermal stability, resistance to light decay caused by 185nm ultraviolet rays, and long life. A high-quality energy-saving lamp is equivalent to 3 to 8 inferior energy-saving lamps. The use time of the lamp, but the price is high. The counterfeit and inferior products use halogen powder or rare earth three-color phosphor mixed with halogen powder mixed powder coating. Its luminous efficiency is 30% lower than that of rare earth three-color phosphor, low color rendering index, and poor thermal stability. , The light decay is serious and the life is short, especially not suitable for use in thin tube fluorescent lamps.
5. Look at the quality of electronic ballasts:
High-quality products are produced through reasonable circuit design and selection of high-quality electronic components. They have low heat generation, high power factor, filter components, low harmonic content, basically no electromagnetic interference to electrical equipment, and high-frequency design. Reach the level of non-stroboscopic flash source, protect people's eyesight and health. In order to save production costs, fake and inferior products are assembled and produced through outsourcing inferior electronic ballasts. The quality cannot be guaranteed, the failure rate is high, and serious fires may be caused. Security issues.
