The main advantages of LED lamps and other lamps are: energy saving, long life, and environmental protection. But quality LED lamps on the market is uneven, said this led integrated ceiling lighting fixtures, product quality on the market will have a big gap. So how do you choose integrated ceiling led lights ? The following small series for everyone to briefly introduce.
First, see if the work is fine?
A good quality LED lamp, in addition to the above mentioned several major aspects, but also according to different use of the environment, there are different technical requirements, such as moisture, dust, magnetic, lightning and so on.
Second, look at the overall "power factor of the lamp": low power factor, indicating that the use of power supply, circuit design is not good, will greatly reduce the life of the lamp, low power factor, the use of a good lamp lamp life will not be long .
The power factor can be detected with the "Power Factor Meter"! General export LED lamp power factor requirements to reach 0.85 or more. Power factor is lower than 0.5, it should be said that unqualified products or garbage products, not only short life, and the actual power consumption is about twice as high than the nominal, that is, compared with ordinary energy-saving lamps, simply do not save power! So, this is why LED lamps need to be equipped with high-quality, high-efficiency drive power!
There is no "power factor meter" consumers, there is a way to use the "current meter" to detect two similar products of the same nominal power, the greater the current and current harmonics, indicating that the actual power consumption is large, also The less power! At the same time, the current is unstable, which is unfavorable to the life of the lamp beads and the life of the whole lamp!
Third, look at the "lamp beads quality": lamp beads quality is determined by the chip quality and packaging technology. The quality of the chip determines the brightness and light decay of the lamp beads. A good lamp is not only bright and bright, but also has a low light decay.
Fourth, look at the use of driving power lamps, power supply life compared to other parts of the lamp, the life expectancy is much shorter, the life of the power supply affects the overall life of the lamp, lamp beads theoretical life of 5-10 million hours, and the power supply The service life is 0.2-30 thousand hours. The design and material selection of the power supply will determine the service life of the power supply.
Fifth, see the light effect: the same lamp power, the higher the luminous efficiency, the higher the brightness, the same brightness, the smaller the power consumption, the more energy-efficient.
Six, look at the power efficiency, the higher the power efficiency as possible, the higher, indicating that the power consumption of the power itself is smaller, the greater the power output.
Seven, to see if it meets the safety standards? China's LED lighting safety standards have been introduced, please select LED lamps according to national safety standards.
Eight, look at the "heating conditions of lamps - materials, structures": LED lamps heat is also very important, the same power factor lamps and the same quality of the lamp beads, if the cooling conditions are not good, the lamp beads work at high temperatures, light decline will Large, lamp life will be reduced.
At present, the heat-dissipating materials used mainly include copper, aluminum, and PC. The heat conductivity of copper is better than that of aluminum. The thermal conductivity of aluminum is better than that of PC. Nowadays, the heat sink material used for the integrated ceiling is generally made of aluminum, and the best one is for the plug. Aluminium, car aluminum (aluminum extrusions, extruded aluminum) followed, the worst is cast aluminum, insert aluminum cooling effect is best! If you use air convection to dissipate heat, be sure to handle the circuit and power supply insulation issues. Otherwise, the lamp works in a relatively humid environment, and it is prone to circuit short-circuit, resulting in a safety accident!
Editor's summary: Here's how to choose the best integrated ceiling LED. For more information, you can follow this site information.
