How to choose LED tunnel lights
Compared with other lamps and lanterns, LED tunnel lights have the advantages of being ultra-thin, ultra-bright, energy-saving, long-life, and green. However, the quality of LED tunnel lights varies greatly, and many consumers do not know how to choose LED tunnel lights? In fact, the significance of applying LED technology to the field of tunnel lighting affects the healthy development of LED tunnel lights. As a manufacturer of LED tunnel lights, it is the responsibility to introduce and explain how to choose LED tunnel lights.
How to choose LED tunnel lights
1. Look at the overall "power factor of lighting"
The low power factor of the LED tunnel light indicates that the use of the driving power is not good, and the circuit design will greatly reduce the service life of the lighting. The power factor is low, and the lighting life of good lamp beads will not be very long. Power factor can be detected with a "power factor meter". LED tunnel lights need to be equipped with high quality and efficient driving power supply, there is no power factor meter to detect the power factor of LED lighting consumers, there is another way to use an "ammeter" to detect two similar products with the same nominal power The larger the power, the greater the current harmonics, which means that the actual power consumption is larger.
2. Look at the heat dissipation conditions and materials of the tunnel lamp
The lighting and heat dissipation of LED tunnel lights are also very important. When the lamp beads work at high temperatures, the light attenuation will be very large, and the lighting life will be greatly reduced. The main heat dissipation materials used in LED tunnel lights are copper, aluminum, pc, and copper has better thermal conductivity than aluminum, and aluminum has excellent thermal conductivity. The quality of lamp beads depends on the quality of the chip and packaging technology. The quality of the chip determines the brightness and light decay of the lamp bead. A good lamp bead is not only bright and bright, but also has little light decay.
3. Look at the driving power used by the lighting
The life of the power supply of the LED tunnel light affects the overall life of the lighting. The appearance of the LED tunnel light is better than that of engineering plastics driven by aluminum alloys. First, its heat dissipation is good. Second, the transportation and use process can effectively protect the parts inside. It will not be crushed and loosened, reducing the failure rate of the power drive.
All in all, the purchase of LED tunnel lights can be referenced from the above three aspects. One is to look at the overall "power factor of the lighting", the second is to look at the heat dissipation conditions and material requirements of the tunnel lights, and the third is to look at the driving power used by the lighting. In addition, the higher the power of the same lamp beads in the waterproof LED tunnel light, the higher the light efficiency, the higher the brightness, and the stronger the energy saving effect.
