LED energy-saving lamps are also called light-emitting diodes. They are very energy-efficient and have a long life. Buying LED lights has become a choice for many people, but LED energy-saving lamps are generally more expensive. Many people don't know how to buy LED energy-saving lamps. It is easy to buy fake products. . So today, Xiaobian introduces some of the LED energy-saving lamps to help you buy a good product.
First, look at the packaging and trademark
The state mandates that LED lamp manufacturers produce the following contents on the outer packaging: rated voltage, voltage range, rated power, and rated frequency. Generally speaking, the quality of the trademark printing of high-quality products is good, the font is clear and not easy to fall off. The wiping mark with a soft damp cloth is clearly distinguishable and difficult to wipe off, and there are trademarks of the manufacturer and related certification marks. The counterfeit products have poor printing quality, the font is fuzzy and easy to erase, and there is no manufacturer's trademark and related certification mark.
Second, look at the appearance of led light tube
The real LED energy-saving lamp is a three-color tube, which is white and covers it with your hand. It will be whiter. From the perspective of the lamp, it is possible to compare a plurality of lamps together. The shape and size consistency of the lamps are mostly bent and formed by machines, and most of them are products produced on a large scale. The consistency of the product is good, the quality is easy to be guaranteed, and the interchangeability during maintenance is better. Of course, there should be no cracks, looseness, and traces between the interfaces. During the installation and disassembly process, the lamp cap should not be loose.
The plastic shell of the lamp must be selected from the flame retardant type of engineering plastic. Ordinary plastics are easily deformed and flammable, and are prohibited from being used in the production of energy-saving lamps. The two can be easily discriminated from the surface, the latter surface is smooth and shiny, and the surface of the former has a texture similar to frosted glass.
Third, look at the driver
The life of LEDs is not as long as 50,000 hours as the manufacturer says. Now the cross-flow drive certified by the European Union on the market can basically reach 20,000 hours. Since LED lighting grade products are only available for two to three years, it is impossible to know that it can be used for 5 to 10 years without driving, and not bad, so the general manufacturers will be guaranteed for two years.
Fourth, look at the startup performance
LED energy-saving lamp startup has two characteristics: First, the higher the temperature, the easier it is to start; the second is that the lamp is turned off and will not flash. In addition, it is worth mentioning that many LED energy-saving lamps are very dark, which is not good for the life of the bulb. The LED energy-saving lamps should have a power circuit and a PCB board inside.
Fifth, look at the lighting color
Good quality light color uniform, no color difference. For example, warm white is a color temperature, but the poor light color is not uniform. For example, although the 10 lights are warm white, they look different, with color difference, some yellow, some are yellowish or even red. In addition, a good LED has a high color rendering index. The light is on the object, and the object is still the original color. The poor LED will cause the object to be discolored by the light. Simple test method: A batch of lights is lit at the same time, and there is no color difference with the naked eye.
Sixth, look at the temperature at work
When the LED energy-saving lamp is in normal working condition, its temperature rise should be very low. Otherwise, the LED energy saving lamp has a very short life. At the same time, when the energy-saving lamp is lit, there is a rapid flashing, or it is very glaring, indicating that the energy-saving lamp has quality problems.
Seven, see the interference situation
In China, electromagnetic compatibility is a project that must be passed by electrical appliances. However, the detection of this project is very complicated. When users buy lamps, they will see whether they have passed the national electromagnetic compatibility test mark on the packaging, and the second is to bring a medium and short wave radio. When the lamp is working, put the radio nearby, the lower the noise emitted by the short-wave radio station, the better the electromagnetic compatibility of the lamp under test.
