How to install LED flat panel lights? In addition, its purchase and installation is also a knowledge.
LED flat lights are generally installed in bedrooms and other spaces for decoration and lighting, and their lampshades are usually made of high-grade acrylic materials. Simple and practical appearance. This kind of lamp has the advantages of energy saving, environmental protection, dustproof, antistatic, transparency and light stability, and is very popular among people. Because it is an emerging light source, the following introduces the installation of LED flat lights. How to install LED panel light? In addition, its purchase and installation is also a knowledge.
Purchase of LED flat panel lights
1. Power factor
The power factor of Led flat panel lamps can be detected with a "power factor meter"! Low power factor indicates poor driving power supply and circuit design, which will greatly reduce the service life of the lighting. Generally, the power factor requirement of LED flat panel lights is 0.85 or higher, and the power factor is lower than 0.5. It should say that the product is unqualified or rejected. Not only is the lifespan short, but the actual power consumption is about twice the nominal value. Of course, if you want to buy a "power factor meter" when buying this type of lighting product, if you don't have it, you can choose the ammeter to test. The greater the current, the greater the current harmonics, the greater the actual power consumption, and the less energy saved. At the same time, the current is unstable, which is not good for the life of the lamp beads and the life of the overall lighting.
2. Heat dissipation material
The heat dissipation of LED lighting is also very important. For the same power factor lighting and the same quality lamp beads, if the heat dissipation conditions are not good, the lamp beads will work at high temperatures. , the light attenuation will be very large, and the life of the bulb will be very long and shortened. At present, the main heat dissipation materials of LED flat panel lights are copper, aluminum, PC, etc. Generally speaking, the thermal conductivity of copper is better than that of aluminum. The thermal conductivity of aluminum is better than that of PC. Today's heat sink materials are generally aluminum, the best is plugged aluminum, automotive aluminum (aluminum profiles, extruded aluminum), the worst is cast aluminum, plugged aluminum is the best for heat dissipation, so when purchasing such a lamp, you must I’m asking what materials commercial lighting materials are.
3. The quality of the lamp beads
The quality of the lamp beads directly determines the long service life of the flat panel lamp. The quality of the LED flat panel lamp depends on the chip quality and packaging technology. The quality of the chip determines the brightness and light attenuation of the lamp beads. Good lamp beads are not only bright and bright. The light attenuation is also very small. There are currently two main camps on the market, namely imported products and domestic products. Of course, whether you choose imported chips or domestic chips, you must choose high quality.
4. Driving power
The service life of the power supply will affect the overall life of the lighting. The theoretical life of the lamp is 50-100,000 hours, while the life of the power supply is 0-2-3 million hours. The design and material selection of the power supply will determine the service life of the power supply. Aluminum alloy appearance power driver is better than engineering plastic. First of all, its heat dissipation performance is very good. Secondly, the transportation and use process can effectively protect the internal parts from being crushed and loosened, and reduce the failure rate of the power supply drive.
5. Works normally
Good quality LED flat panel light is a high-quality driving power supply, good heat dissipation conditions, high-quality chips and perfect and exquisite workmanship. This is the only way It can be regarded as a good lighting product, suitable for work, as long as you visit the lighting market?
