How to choose led ceiling lamp and how to install flat lamp?

Flat-panel lamps refer to rectangular or square lamps that look thinner. This kind of lamp is more energy-saving and will not often flash. In fact, there are many kinds of flat lamps now. Next, I recommend a product with high quality and low price, that is, led ceiling lamp flat lamp. In fact, led ceiling lamp flat lamp has been used in many occasions. Let's take a look at led ceiling lamps. So, how to choose led ceiling lamp?

How to choose led ceiling lamp?

First look at the overall "power factor" of lighting: low power factor means that the driving power supply and circuit design used are not good, which will greatly reduce the service life of lighting! If the power factor is low, the lighting life of the lamp bead will not be long even if it is used well. The level of power factor can be detected by "power factor table"! Generally, the power factor of LED flat lamps for export should be above 0.85. If the power factor is lower than 0.5, it should be said that it is a substandard product or a junk product, which not only has a short service life, but also the actual power consumption is about twice as high as the nominal one, which means that compared with ordinary energy-saving lamps, it does not save electricity at all! Therefore, this is why LED flat-panel lamps need to be equipped with high-quality and efficient driving power! There is no "power factor table" to detect the power factor of LED lighting. Another method is to use "ammeter" to detect two similar products with the same nominal power. The greater the current, the greater the current harmonic, the greater the actual power consumption and the less energy saving! At the same time, the current is unstable, which is not good for the life of lamp beads and the whole lighting!

Second, look at "lighting heat dissipation conditions-materials, structure": LED lighting heat dissipation is also very important. Lighting with the same power factor and the same quality of lamp beads, if the heat dissipation conditions are not good, the lamp beads will work at high temperature, and the light attenuation will be great, and the lighting life will be shortened. The main heat dissipation materials used are copper, aluminum and PC. The thermal conductivity of copper is better than that of aluminum, and that of aluminum is better than that of PC. At present, aluminum is the most commonly used radiator material, the best is inlaid aluminum, followed by automobile aluminum (aluminum profile and extruded aluminum), and the worst is cast aluminum. Aluminum has the best heat dissipation effect!

Third, look at "the quality of lamp beads": the quality of lamp beads depends on the chip quality and packaging technology.

The quality of the chip determines the brightness and light attenuation of the lamp bead. Good lamp beads not only have high brightness, but also have small light attenuation.

Fourth, look at the driving power supply for lighting. Compared with other parts of lighting, the service life of power supply is much shorter. The service life of power supply affects the overall service life of lighting. The theoretical life of the lamp bead is 5-65438+ 10,000 hours, while the life of the power supply is 0.2? -30,000 hours, the design and material selection of the power supply will determine the service life of the power supply. The power drive of aluminum alloy to appearance is better than that of engineering plastics. First, good heat dissipation. Second, it can effectively protect internal parts from being crushed and loosened during transportation and use, and reduce the failure rate of power drive.

How to install a flat lamp

(1) When installing the living room flat lamp in the masonry structure, should it be fixed with embedded bolts or with expansion bolts, nylon plugs or plastic plugs? ; Don't use wooden wedges. And the bearing capacity of the fixing piece should match the weight of the living room flat lamp. Ensure that the flat lamp in the living room is fixed firmly and reliably, and prolong its service life.

(2) When the expansion bolt is used for fixing, the bolt specification should be selected according to the technical requirements of the product, and the drilling diameter and buried depth should be consistent with the bolt specification.

(3) The number of bolts for fixing the lamp holder should not be less than the number of fixing holes on the lamp holder, and the diameter of the bolts should match the aperture; For lamps without fixed mounting holes on the base (self-drilling during installation), there should be no less than two bolts or screws for fixing each lamp, and the center of gravity of lamps should be the same as that of bolts or screws; Only when the diameter of the insulating platform is less than or equal to 75mm can it be fixed with 1 bolts or screws.

(4) The flat lamp in the living room cannot be directly installed on flammable materials. For the sake of beauty, some families line the back of the flat lamp in the living room with colored plywood. In fact, this is very dangerous and heat insulation measures must be taken. If the high-temperature parts on the surface of lamps are close to combustible materials, heat insulation or heat dissipation measures should also be taken.

(5) Before installing flat-panel lamps in the living room, it should also be checked: ① Lead out the conductor core section of each lamp, with the soft copper core not less than 0.4 mm2 and the copper core not less than 0.5 mm2, otherwise the conductor must be replaced. (2) The connection between wires and lamp holders, and the connection between parallel wires between lamp holders should be firm? Solid and electrical contact should be good, so as to avoid danger caused by sparks between wires and terminals due to poor contact.

The above is a detailed introduction of led ceiling lamp flat lamp. After reading the above, we know that the led ceiling lamp has a remarkable effect. Many friends like led ceiling lamps and flat lamps very much. There are many brands of led flat lamps on the market, such as NVC, Opal and Yaming. These brands of lamps are very famous. After reading the article, everyone has a deep understanding of led ceiling lamps. For led ceiling lamps, you should learn more and buy them well.
