Today's Focus: Energy Saving Lamps

Key indicators

1.Lamp size. The lamp caps specified in the national standards are screw caps or bayonet caps. The quality of the lamp cap involves the interchangeability of the energy-saving lamps and safety requirements such as protection against electric shock. The unqualified lamp caps can easily cause the lamp to fall off from the lamp holder and cause electric shock.

2.Mechanical strength. Mechanical strength is a measure of the degree of firmness of the lamp head and the lamp body. The standard specifies that the lamp head should be firmly connected with the lamp body and should be able to withstand a certain amount of torque. If the strength of the connection between the lamp cap and the lamp housing is too low, the screwing or unscrewing of the torque when the user installs or replaces the lamp tends to cause the lamp cap to be detached from the lamp housing, lightly affecting the use of the lamp and causing the internal conductor to break. Short circuit.

3.Power.The standard requires that the difference between the power actually consumed by the lamp and the rated power should not exceed 15%. This indicator is an important basis for consumers when selecting lamps. When the actual power consumption of the lamp is too far from the nominal power, the light output of the lamp will be greatly reduced. This is one of the main manifestations of counterfeit and shoddy products.

4.Initial light efficiency / luminous flux. The initial luminous efficiency is the ratio of luminous flux to actual consumed power. It is an important index for objectively evaluating whether energy-saving lamps are energy-efficient. Self-ballasted fluorescent lamps have energy efficiency grades of 3, with the highest energy efficiency at grade 1 and the lowest energy efficiency at grade 3. The initial light efficiency and light decay are fast, which is also one of the main features and means of counterfeit products.

5.Lifetime.The standard requires that the rated life of the energy-saving lamps should not be less than 6000 hours.The long service life is an important advantage of the use of energy-saving lamps. At present, due to the unreasonable circuit design of some production companies, poor quality lamps or electronic components have been selected, resulting in an average lamp life of less than 6000 hours and consistency. It is very poor, and it gives consumers the feeling of saving money without saving money.

6.Harmonic current. Harmonic current should be as small as possible. Due to the limitations of energy-saving lamp size and cost, most of the energy-saving lamps are made with low power factor and harmonic currents are large. Although a single lamp may meet the requirements of the standard, there may be batch damage or even a danger to the safety of the power grid when large quantities are used together. This problem has occurred many times.

Purchase tips

1.Look at the packaging. First of all, the packaging and printing should be given clean and clear, should be marked with the name of the manufacturer; Second, should purchase a 3C certification mark and energy efficiency labeling for the 1st or 2nd; Finally, to select the appropriate power, color temperature .

2.Look at the real thing. The appearance of the energy-saving lamp should be neat and clean with clear signs; the glass bulb of the lamp should be smooth, the phosphor coating in the lamp tube should be uniform and free from particles, and the glass bulb and phosphor layer at the bend should not be too thin or have to come off. Powder; hand shaking lamp, lamp and lamp shell connection should not be loose, there should be no internal noise; lamp and lamp should not tilt; lamp thread should be neat and smooth, the lamp head solder should be flat; hard to screw the lamp and Lamp shell, its connection should be solid and reliable.

3.Pilot lights. First, when the lamp is screwed in and out of the lamp holder, it should be smooth; secondly, when the power is turned on, there should be no magenta light in the part of the lamp tube near the plastic shell. There should be no noise, and no flickering should occur. Can be lighted up; Third, there should be no light rolling light tube. The high-grade lamps themselves emit more dazzling, pure colors, and the low-grade lamps are darker in color. The powder layer of the spiral tube should not have serious uneven stripes; Fourth, after switching off the power, the lamp should not flash back.

4.Compare prices. The price of energy-saving lamps is related to brands, quality, types, and power. Below 10 watts of U-shaped energy-saving lamps prices below 10 yuan, the price of spiral tube energy-saving lamps below 13 yuan, generally low-grade products.

5.Pay attention to power. For high-volume centralized use of energy-saving lamps in public places, you should purchase energy-saving lamps with high power factory.
