LED lamp and energy-saving lamp which is good LED ceiling lamp purchase tips
With the continuous development of science and technology, there are many types of lamps. LED lamps and energy-saving lamps are more popular now. Both of them are more energy-saving and environmentally friendly lighting products. Many people do not particularly understand these two types of lighting. Which is better, lamp or energy-saving lamp? In the process of home decoration, what are the tips for purchasing LED ceiling lights? Let's follow Benwei to find out.

Which is better, led lamp or energy-saving lamp:
1. In terms of working efficiency, high-efficiency fluorescent tube energy-saving lamps above 20W are similar to high-power LED lamps. Lamps below 20W have LED working efficiency higher than ordinary fluorescent energy-saving lamps (mostly ordinary fluorescent tubes below 20W) Energy-saving lamps).
2. Energy-saving lamps are easily damaged and have a short lifespan. The service life of LED lamps can reach more than 100,000 hours and can work at high speed. If the energy-saving lamp is frequently turned on or off, the filament will turn black and quickly break down.
3. Mercury pollution occurs during the production process of energy-saving lamps and after use and disposal. At present, Western countries attach great importance to mercury pollution, and Chinese people are increasingly aware of the harmfulness of mercury pollution. LED lights are environmentally friendly and have no harmful substances of mercury.
4. Energy-saving lamps consume more power. White LED lamps consume only 1/10 of incandescent lamps and 1/4 of energy-saving lamps. Therefore, LED lamps are more power-efficient.
5. Because energy-saving lamps are glass products, they are easy to break, difficult to transport, and difficult to install. The solid-state package of LED lamps belongs to the type of cold light source, so it is very convenient to transport and install, and can be installed in any miniature and enclosed equipment. It is not afraid of vibration and basically does not need to consider heat dissipation.

The above is a brief introduction about which is good for led lamps and energy-saving lamps. I believe that after the above introduction, everyone will have a further understanding of these two kinds of lighting. As for which is good, everyone's preferences are different. It is recommended It’s best to choose according to your own preferences and actual conditions, but I personally think that LED lamps are better. LED lamps have good power saving effects, long service life, no stroboscopic effect, no noise, soft lighting, and general ceilings. Many people choose LED installations for lights. Faced with so many LED lighting products on the market, what are the tips for purchasing LED ceiling lights? Take a look at the following introduction:
Tips for purchasing LED ceiling lights:
1. See if the workmanship is fine:
In addition to the main aspects mentioned above, a good-quality LED lamp has different technical requirements according to different use environments, such as moisture-proof, dust-proof, anti-magnetic, and anti-lightning.
2. Look at the overall "power factor of lamps and lanterns":
The low power factor means that the driving power supply and circuit design used are not good, which will greatly reduce the service life of the lamp. No matter how good the lamp beads are used, the lamp life will not be long. The power factor level can be detected with the "power factor meter" , Generally, the power factor of export LED lamps is required to reach 0.85 or more, and the power factor is less than 0.5. It should be said that unqualified products or junk products, not only have a short lifespan, but also the actual power consumption is about twice as high as the nominal value, that is to say, Compared with ordinary energy-saving lamps, it does not save electricity at all! Therefore, this is the reason why LED lamps need to be equipped with high-quality and high-efficiency driving power. For consumers who do not have a "power factor meter", there is another way to use an "amperometer" to detect two similar products with the same nominal power. , The larger the current and the larger the current harmonics, it means that the actual power consumption is larger, and the less power is saved! At the same time, the current is unstable, which is detrimental to the life of the lamp beads and the life of the overall lamp.
3. Look at the "Quality of Lamp Beads":
The quality of the lamp beads is determined by the chip quality and packaging technology. The chip quality determines the brightness and light decay of the lamp beads. A good lamp bead not only has high luminous flux, but also has low light decay.
4. Look at the driving power used by the lamps:
Compared with other parts of the lamp, the service life of the power supply is much shorter. The service life of the power supply affects the overall life of the lamp. The theoretical life of the lamp bead is 50,000 to 100,000 hours, while the life of the power supply is 20,000 to 30,000 hours. The design and material selection will determine the service life of the power supply.
5. Look at the light effect:
The same lamp bead power, the higher the luminous efficiency, the higher the brightness, the same lighting brightness, the lower the power consumption, the more energy-saving.
6. Look at the power efficiency:
The higher the efficiency of the power supply, the better, and the higher it is, the lower the power consumption of the power supply itself, the greater the output power.
7. See if it meets safety standards:
my country's LED lighting safety standards have been issued, please choose LED lighting according to the safety standards stipulated by the country.
8. Look at "heat dissipation conditions of lamps and lanterns-materials and structure":
The heat dissipation of LED lamps is also very important. For lamps with the same power factor and lamp beads of the same quality, if the heat dissipation conditions are not good, the lamp beads will work at high temperature, the light decay will be large, and the lamp life will be reduced. At present, the heat dissipation materials used There are mainly copper, aluminum, and PC. Copper has better heat conduction than aluminum, and aluminum has better heat conduction than PC. Now the flat light radiator materials used in integrated ceilings generally use aluminum the most, and the best is the insert aluminum and the car aluminum ( Aluminum profile, extruded aluminum), the worst is cast aluminum, and the insert aluminum has the best heat dissipation effect. If air convection is used to dissipate heat, the insulation problem of the circuit and power supply must be dealt with. Otherwise, the lamps are comparing Working in a humid environment is prone to short circuits and cause safety accidents.
