Why LED lights the best price and quality?

Recently, the public Liu to the supermarket to buy light bulbs, lamp array can be on the shelves, let him pick dazzled. "In addition to traditional incandescent and energy-saving lamps, there is a LED light, I do not know how the lighting effects of the lamp?" Incandescent, energy saving lamps, high LED light which price? Found through experiments, home lighting or LED lights cost .

LED light is 16 times more expensive than incandescent

Currently, the incandescent lamp is facing a situation of being phased out, energy-saving lamps into the mainstream market. Reporters saw at a large supermarket, energy-saving lamps become flagship product, the rise of new LED lights are difficult to buy, while the incandescent lamp has been hard to find. Judging from the appearance, with different shapes CFL lamps, LED lamp bulb is spherical, similar to incandescent lamps. But the packaging label display, LED lamp power is far lower than ordinary incandescent lamp.

"You're holding a light bulb is 5 watts of power, lighting brightness equivalent to 40 watt incandescent." Supermarket shopping guide told reporters, pick brightness LED lamps and energy-saving lamps is to look on the box marked with incandescent correspondence wattage. Reporters also noted that the addition of a labeled 3-watt LED lights, its illumination is equivalent to 25 watt incandescent.

Shopping guide told reporters that many people still choose incandescent or energy-saving lamps, LED bulbs to buy not many customers. "LED lights are too expensive." Reporters noted that a certain brand of 5-watt LED lamp price of 49.8 yuan, 16 times more than other energy-saving lamps or incandescent expensive. However, I understand, marked the life of this LED lights up to 15 years.

Incandescent most power

So, these types of bulbs to use the common market of the actual results so far? Here comparative tests (3) of the common market on the bulb.

3 bulbs are incandescent, energy saving lamps and LED lights, prices ranging from three yuan to 49.8 yuan. Wherein the incandescent lamp rated at 40 watts, energy-saving lamp rated power of 8 watts, which corresponds to the nominal brightness 40 watt incandescent, LED lights and a power rating of 5 watts, the nominal brightness equivalent to 40 watts incandescent.

Experiment, in a dark room, these three bulbs are connected to the 220 volts of lamp, the measured current ammeter to measure the actual power the lamp. Meanwhile, the three bulbs in the box is placed at a distance of 30 cm bulb, a fixed amount of exposure by the camera shot of the box reflective case, as intuitive feelings distinguish three bulbs.

Through the test current, and soon we come to the actual power three light bulbs. An incandescent lamp current of approximately 0.18, found about 40 watts of power; energy-saving lamp current of approximately 0.035 Ann, measured about 7.7 watts of power; LED lights approximately 0.021 Ann, measured about 4.6 watts of power. From these data point of view, the highest measured power incandescent lamp, is the most power-hungry.

LED lights the brightest and most "cold"

So, the actual lighting effects three bulbs and how? In the same exposure combination shoot a group of photos, recording the different light bulbs box reflective, the photo display, LED bulb, although only 5 watts nominal power, the brightness but the highest. Incandescent lamp brightness is slightly lower, although sporadic yellow looks very bright, but it feels relatively soft. CFL lamp shape is back to form larger light-emitting area, but white color, look at slightly harsh.

With the equivalent of 40 watts or 40 watts, why lighting effects there's the difference? This is because, incandescent and energy-saving lamps to the surrounding light is diverging, while LED lamp light is emitted in one direction, so it is more than the other two bulbs brighter.

In the heat, the use of incandescent bulbs in two minutes after the temperature is too high can not touch it directly, although significant energy saving lamps fever, but the hand holding the lamp does not feel very hot, while the LED bulb is minimal, only light bulb near the mouth, you can feel when you touch lukewarm.

LED lights highest price

Just from the price point of view, buy a LED light, equivalent to the purchase of 16 incandescent, buy an energy-saving lamp, it is equivalent to spending nine incandescent price. Buy LED lights clearly not cost-effective energy-saving lamps and incandescent lamps. But count factors such as power consumption and lamp life, the LED lighting life of 15,000 hours, equivalent to 15 incandescent or energy-saving lamps and three. On consumption, incandescent need to consume 600 kWh, energy-saving lamps to 115.5 degrees, while the LED lamp is only 69 degrees.

According to 0.48 yuan per kilowatt basis, the use of 15,000 hours, the electricity generated by the use of incandescent lamps is 333 yuan, energy-saving lamps to 139.44 yuan, while LED lights only 82.92 yuan. If long-term use, or the most cost-effective LED lights, and the best lighting effects.

Energy-saving lamps do not worry?

Living room chandeliers, desk lamps, bedside lamps ...... At present, energy-saving lamps universal access to family, be welcomed by consumers. However, for energy-saving lamps controversy has continued, "radiation carcinogenesis" and "hurt the eyes discontinuous spectrum," the statement caused a lot of controversy.

Energy-saving lamp is actually a compact, self-ballast fluorescent lamps. Power, the mercury atoms inside a tube to release the human eye can not see ultraviolet light, the ultraviolet light hit the inner wall of the phosphor coating, then converted into a visible light. However, it is precisely this road the invisible ultraviolet light, so that energy-saving lamps labeled a "radiant light" hat.

It is understood that energy-saving lamps will indeed release a small amount of ultraviolet light, but in fact, all the lights will be doing. Energy-saving lamps emit ultraviolet content is very low, in the range that people can afford. For the public, deal with energy-saving lamps radiate a variety of initiatives, the most direct way is to buy low-E energy-saving lamps. The second way is to check the product before the purchase of energy-saving lamp test reports, in accordance with the "field strength shall not exceed 200 V / m, magnetic field strength should be less than 10 micro Tesla" standard purchase.

Wave radiation in the transmission will continue to weaken with distance, away from energy-saving lamps, can further reduce the chance of injury. So, to be safe, it is best to make energy-saving lamps to maintain a certain distance from the human body, in general, as long as energy-saving lamps to keep one meter distance is safe. Best not to choose to use energy-saving lamps in a position relatively close distance of the head, such as: the bedside reading lights and so on.

A more important question about energy-saving lamps, is waste lamp recycling, because the mercury lamp will cause great environmental pollution, mercury and toxic substances belonging to the body disposable inhaler more than 2.5 g may lead to death. Members of the public in the use of energy-saving lamps must be prevented from being damaged, discard the lamp should be marked to remind, to avoid harm to others.

From October ban incandescent lighting ≥60 Wapu

2014 just opened, the "ban incandescent" are listed on the delisting agenda in Asia. From January 1, the US market stopped selling the best-selling 40-watt and 60-watt incandescent, South Korea, Thailand, the Philippines have also taken measures to promote energy-saving lamps have. October 1 this year, China also will ban the import and sale of 60 watts and above ordinary incandescent lighting. Industry insiders said, LED lighting market suddenly "lit" up, will open in 2014 to replace the light source in the world.

Reporters learned that, in fact, in 2011 China had the incandescent phase-out schedule, according to the incandescent phase-out plan, after the transitional period, 100 watts and above ordinary incandescent lighting came into effect October 1, 2012 banned the import and Sales. This year will enter the third stage, from October 1, 2014 banned the import and sale of 60 watts and above ordinary incandescent lighting. October 1, 2015 to September 30, 2016 for the mid-term evaluation period; since October 1, 2016 banned the import and sale of 15 watts and above ordinary incandescent lighting, or, as the mid-term evaluation results to adjust.

Illuminating Engineering Society experts say, incandescent tungsten filament produces heat emitting by only 5% in the use of electricity for lighting, the remaining 95% of the total consumed by the heat. Energy-saving lamps are able to 80% of the electrical energy into light, LED lights can be directly put electricity into light, lower power consumption. "After the light source replacement, energy-saving lamps and LED lights will occupy lighting market."
