LED lights to consume 25 percent of the energy used in energy saving lamps, because ordinary energy-saving lamps still consume some of the electricity to be converted to heat, and LED lights don’t have that problem. LED lights have a longer lifespan, and quality LED bulbs can last between 10,000 and 20,000 hours, while the same energy-saving lamps can last between 6,000 and 10,000 hours.
LED lights are more environmentally friendly. Mercury is one of the indispensable luminescent materials for energy saving lamps. As time goes by, the sealing of energy saving lamps will appear gaps, among which the mercury will evaporate into the air and cause pollution to the air. LED lights are completely free from this problem and are safe and environmentally friendly. LED lights are much better than energy-saving bulbs in terms of anti-seismic and lightning protection. The effect of the continuous switch caused by an unstable voltage on the LED is much less than that of the energy saving lamp.
And energy-saving lamp if frequent switch, service life can be greatly reduced. At present, one of the major reasons for the obstacles to the promotion of LED lights is that the price is too expensive. For ordinary users, service life, energy conservation, and environmental protection, after all, can’t be directly observed, only the price can be directly perceived. However, considering the advantages of LED lamps mentioned above, the installation cost is acceptable. After all, the service life is so long, and the stability is not bad. In the long run, it is definitely cheaper than buying energy-saving lamps.
LED energy-saving lamps are increasingly popular among consumers due to their features of obvious power saving effect, long service life, no stroboscopic effect, no noise, soft light, and wide operating voltage range. But there are a lot of LEDs on the market, both good and bad. How to choose the product that oneself is satisfied with the energy saving lamp of full of beautiful things in lamps and lanterns shop? Through the “five looks” can identify the pros and cons of energy-saving lamps, introduced as follows.
LED lighting manufacturer is required to mark the following contents on the outer package: rated voltage, voltage range, rated power, and rated frequency. Generally speaking, the trademark of high-quality products is printed with good quality, the font is clear, not easy to fall off, wipe with a soft wet cloth, the mark is clear, not easy to erase, and there are the trademarks of manufacturers and related certification marks. The poor printing quality of fake and inferior products, blurry font, easy to erase, no manufacturer’s trademark and related certification mark.
Real LED energy-saving lamps, with a three-color tube, tube white, with the hand covered to see, more white. Additional, look from lamp tube, can put many lamps together to compare, lamp tube shape and dimension are consistent better to machine bend fold molding, it is the product that produces on a large scale more. The product has good consistency, quality is easy to be guaranteed, and interchangeability is better during maintenance. Of course, there should be no visible cracks, loose or pried marks between the joints. During installation and disassembly, the lamp holder should not be loose and tilt.
The lamp’s plastic case must be of the engineering plastic flame retardant type. Common plastics are deformable and flammable and are prohibited from being used in the production of energy saving lamps. The latter has a smooth and lustrous surface, while the former has a similar texture to sanded glass.
LED bulb lamp under the normal working condition, its temperature rise should be very low. Otherwise, LED bulb lamp life is very short. At the same time, when the energy-saving lamp lights up, there is a quick flash, or very dazzling fluctuations, which indicates that the energy-saving lamp has quality problems.
The LED lamp starts with two characteristics: first, the higher the temperature, the easier it is to start; The second is that the lights are turned off and do not flash. In addition, it is worth mentioning that many LED energy-saving lamps are dark on, which is bad for the life of the bulb. The LED energy-saving lamps should be equipped with a power circuit and PCB board inside.
In our country, the electromagnetic compatibility is appliances must pass the project, however, this project is very complicated, the light users buy a look at the package whether have through the national flag of electromagnetic compatibility test, 2 it is to take a medium shortwave radio, when the lamp is working, turn the radio on nearby, radio to medium shortwave radio station in the lower noise, electromagnetic compatibility of the measured light is better.
In terms of working efficiency, the high-efficiency fluorescent tubes over 20W are similar to the high-power LED lamps. The working efficiency of LED of lamps under 20W is higher than that of ordinary fluorescent energy-saving lamps (most lamps under 20W are conventional fluorescent tube energy-saving lamps).
The service life is better than LED lamps, which is about five times as long as that of ordinary fluorescent tubes, and twice as long as that of efficient fluorescent tubes.
LED does not contain toxic substances; Fluorescent tube energy – saving lamp breaks in the work, can leak toxic mercury vapor.
For color rendering, both LED and fluorescent tube energy-saving lamps can be above 0.9. The two have slightly different spectral characteristics, but the color performance of low cost LED lamps is worse than that of fluorescent tubes.
LED light sources are often combined with lamps. Therefore, the high-efficiency fluorescent tube energy saving lamp is more suitable for over 20W. Below 20W, LED lamps are appropriate. Under 20W of the ordinary fluorescent fluorescent lamp or price advantage. The smaller night lights under 2W are already non-led.
Synthetically before and after light source history development. LED lights have huge advantages. On the brightness of the 8W bulb, the lamp can be top of 17W home spiral energy – saving lamp test. The 12WLED bulb can completely replace the general fluorescent lamp. (I said full power LED bubble, online gray goods do not comment), save electricity to see the power contrast. LED8W< spiral CFL 17W. Lifespan: 50, 000 hours of LED in theory and 20, 000 hours in practice (temperature seriously affects lifespan). 20,000 hours. Six hours a day. Available for 3333 days. Eye protection: please do not buy lamps and lanterns of unknown origin. At present, it is proposed that the blue light of the LED lamp can hurt the eyes, deviate from the evolution of the sunlight to the eyeball, and buy the lamps produced by normal manufacturers first. Second, turn on the phone camera to light up the lamp and see if the screen is flashing. It means stroboscopic. You can get visual fatigue.
