Collection! How to buy LED flat purification lamp
Compared with other lighting fixtures, LED flat purification lamps have outstanding advantages: ultra-thin, ultra-bright, ultra-energy-saving, ultra-long life, ultra-saving and worry-free! Green. However, the quality of LED panel lights varies greatly, and consumers do not know how to choose?
In view of the vicious competition in the market price of flat panel lamps, a large number of substandard products are listed (professionals call it (bad, bad, bad), which has violated the true value of LED energy saving, long life, environmental protection, etc., and violated the LED The significance of the application of technology to the field of integrated ceilings has seriously affected the healthy development of integrated ceiling LED flat-panel purification lamps. As the manufacturer of LED flat-panel purification lights, it is the responsibility to introduce and explain to everyone how to choose LED flat-panel purification lights or identify LED flat-panel purification The quality of the lamp:
1. Look at the overall "power factor of lighting": low power factor means that the driving power and circuit design used are not good, which will greatly reduce the service life of the lighting! Low power factor, no matter how good the lamp beads are used, the lighting life will not be long .
The level of power factor can be detected with a "power factor meter"! Generally, the power factor of export LED flat lights is required to reach 0.85 or more. If the power factor is lower than 0.5, it should be said that substandard products or junk products not only have a short lifespan, but also the actual power consumption is about twice as high as the nominal. That is to say, compared with ordinary energy-saving lamps, it does not save electricity at all! , This is why the LED flat panel purification lamp needs to be equipped with high-quality and high-efficiency driving power! Consumers who do not have a "power factor meter" to detect the power factor of LED lighting, there is another way to use an "amperometer" to detect the second A similar product with the same nominal power, the larger the current and the larger the current harmonics, the greater the actual power consumption, and the less power saving! At the same time, the current is unstable, which is detrimental to the life of the lamp beads and the life of the overall lighting!
2. Look at "Lighting Heat Dissipation Conditions--Material and Structure": The heat dissipation of LED lighting is also very important. For lighting 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 under high temperature and the light will decline. Very large, the life of the lighting will be reduced. The main heat dissipation materials used are copper, aluminum, and PC. Copper has better heat conduction than aluminum, and aluminum has better heat conduction than PC. Nowadays, aluminum is generally used as the most radiator material, which is insert aluminum and car aluminum (aluminum profile, extruded aluminum) Secondly, the worst is cast aluminum, and the insert aluminum has the best heat dissipation effect!
3. Look at the "lamp bead quality": the quality of the lamp bead is determined by the chip quality and packaging technology.
The quality of the chip determines the brightness and light attenuation of the lamp beads. Good lamp beads not only have high luminous flux, but also have low luminous decay.
4. Look at the driving power used by the lighting. The service life of the power supply is much shorter than that of other parts of the lighting. The service life of the power supply affects the overall life of the lighting. The service life is between 0.2 and 30,000 hours. The design and material selection of the power supply will determine the service life of the power supply. The appearance of the power drive with aluminum alloy is better than that of engineering plastics. One is that it has better heat dissipation. The other is that the parts inside can be effectively protected from being crushed and loose during transportation and use, and the failure rate of the power drive is reduced.
5. Look at the light effect: the same lamp bead power, the higher the light effect, the higher the brightness, the same lighting brightness, the less power consumption, the more energy-saving.
6. Look at the efficiency of the power supply. The higher the efficiency of the power supply, the better, and the higher it is, indicating that the power consumption of the power supply itself is smaller and the output power is greater. After reading the above points, do you know how to distinguish it now?
