The vicious price competition in the LED lighting market and the listing of a large number of substandard products have violated the true value of LED energy saving, longevity and environmental protection. The LED lamp market is facing a severe test! How to distinguish the advantages and disadvantages of LED lighting should start from the following aspects
1. Check the overall power factor of the lamps
A low power factor indicates that the driving power supply and circuit design used is improper, which will greatly reduce the life of the lamp. Low power factor will not prolong the life of lamps using the best lamp beads.
2. Check the heat dissipation of lamps and lanterns - material, structure
The heat dissipation of LED lighting is also very important. For lamps with the same power factor and bulbs with the same quality, if the heat dissipation conditions are not good, the bulbs will work at high temperatures, resulting in large light attenuation and shortened lamp life.
The radiator of the LED lighting fixture adopts a transparent design. This design can take full advantage of the principle of air convection to take away a lot of heat and prolong the service life of the light source.
3, is to see if the workmanship is fine
In addition to the above-mentioned main aspects, a good quality LED industrial lamp also has different technical requirements according to different use environments, such as moisture-proof, dust-proof, anti-magnetic, lightning-proof and so on.
4. Check the lamps that drive the power supply
The life of the power supply is much shorter than other components of LED lighting. The service life of the power supply affects the overall service life of the luminaire. The theoretical service life of the lamp beads is 500,000-100,000 hours, and the service life of the power supply is 0.2-30,000 hours. The design and material selection of the power supply will determine the life of the power supply.
5. Look at the quality of the lamp beads
The quality of lamp beads depends on chip quality and packaging technology.
6. Look at energy efficiency
The higher the efficiency of the power supply, the better, the higher the higher, the lower the power consumption of the power supply itself, the greater the output power.
7, is to see whether it meets the safety standards
China's LED lighting safety standards have been released, please choose LED lamps according to the national safety standards.
8. Look at the lighting effects
Under the same lamp bead power, the higher the luminous efficiency and the higher the brightness of the LED lighting, the lower the power consumption and the more energy-saving under the same lighting brightness.
