With the progress of the times and the progress of the society, when people buy home decoration, they not only consider the practicability, but also consider the decoration and decoration, and the decoration and lighting together are more attractive. Today, the technology and characteristics of LED panel light are introduced.
1、 Purchasing skills of LED flat lamp
Compared with other lighting, the advantages of LED flat lamp are very outstanding: ultra thin, ultra bright, ultra energy saving, ultra long life, ultra energy saving! Green environmental protection. However, the quality of LED panel lights is very different, consumers do not know how to choose?
1. Look at the overall "lighting power factor": low power factor, indicating that the use of driving power, poor circuit design, will greatly reduce the service life of lighting! Low power factor, lamp bead decoration life is not long. Power factor meter can detect power factor. In general, the power factor of the exit LED flat light is more than 0.85. If the power factor is less than 0.5, it should be said that unqualified products or garbage products not only have short service life, but also the actual power consumption is about twice higher than the nominal power consumption. That is to say, compared with ordinary energy-saving lamps, there is no power saving at all! So, that's why LED flat lights need to be equipped with high-quality, high-efficiency driving power! There is no "power factor meter" to detect the power factor of LED lighting electrical equipment. Another method is to use "ammeter" to detect two similar products with the same power rating. The greater the current, the greater the harmonic current, the greater the actual power consumption, and the smaller the power saving! At the same time, the current is not stable, the life of lamp beads and the life of the whole lamp decoration are not ideal.
2. Look at "lighting and heat dissipation conditions - material and structure": LED lighting and heat dissipation are also very important. With the same power factor and the same quality of beads lighting, if the cooling conditions are not good, beads will work at high temperature, light attenuation will be very large, lighting life will be reduced. The main heat dissipation materials used are copper, aluminum and PC. copper heat conduction is better than aluminum, and aluminum heat conduction is better than PC. at present, the radiator material is generally aluminum, which is better to insert aluminum and automobile aluminum (aluminum profile, extruded aluminum), the worst is cast aluminum, and the heat dissipation effect of aluminum insert is better!
3. Look at "bulb quality": bulb quality depends on chip quality and packaging technology. The quality of the chip determines the brightness and light failure of the bulb. Good lamp beads are not only bright, but also light attenuation is small.
4. From the perspective of the driving power used in lighting, the service life of the power supply is much shorter than that of other lighting parts. The service life of power supply affects the overall life of lighting. The theoretical life of lamp beads is 5-100000 hours, and the service life of power supply is 0.22-30000 hours. The design and material selection of the power supply will determine the service life of the power supply. The driving performance of aluminum alloy is better than that of engineering plastics. First, good heat dissipation performance. Second, in the process of transportation and use, it can effectively protect the internal parts from extrusion and loosening, and reduce the failure rate of power transmission.
5. Light effect: the same lamp bead power, the higher light efficiency, the higher brightness, the same lighting brightness, the smaller power consumption, the more energy saving. From the perspective of power efficiency, the higher the power efficiency, the better, the higher the power consumption of the power supply itself, the greater the output power.
2、 Characteristics of LED panel lamp products
1. LED flat lamp adopts liquid crystal backlight technology and efficient LED chip, with unique heat dissipation design, to ensure high efficiency, low light attenuation and long life of LED.
2. The surface is bright, bright, even, soft and not dazzling.
3. 100-240Vac input voltage, high power efficiency. Start up time is short, do not flash.
4. The lamp is light in weight and easy to install. Environmental protection, safety, pollution-free, RoHS compliant.
5. Stable performance, low maintenance rate. The invention has the advantages of strong universality, convenient installation, space saving, etc,
6. The service life of LED panel lamp is more than 30000 hours, even if it is opened frequently, it will not affect the service life of the product.
7. Green lighting products, free of mercury, lead and other pollution elements;
8. LED flat lamp is free of ultraviolet and infrared rays to avoid radiation damage to objects.
9、 The flexible lighting technology is used to expand the LED panel lamp into a surface light source, eliminating glare, visual fatigue and sublimation visual effects;
10. LED flat lamp has high color rendering index, strong color reduction, clear vision and no object deformation, which is suitable for commercial lighting places;
11. No stroboscopic and pure DC operation, eliminating the visual fatigue caused by stroboscopic of traditional flat lamp.
