LED lamps and lanterns have been very popular in the market because of their energy-saving, beautiful, light source color, variety and many other advantages, and also favored by consumers. However, when consumers face the complex LED market, how to refine a pair of fire eyes, can accurately identify the cheap LED lamps and lanterns?
In the era of energy-saving lamps and LED lamps, society has been paying far more attention to these lamps than in any period of the development of lamps. At the same time, some medical professionals and electric light source experts pointed out that many LED lamps have serious blue light overflow problems, long-term time will cause the human eye retina by a great degree of damage.
LED lamps can cause a glare hazard. Glare is in the field of vision due to the vision of discomfort of the human body and reduces the visibility of the object, glare is one of the important factors to judge the quality of lighting.
Improper selection of heat dissipation material for LED lamps
Nowadays, under the influence of low market demand, plastic heat-dissipation materials are widely used in LED lamps. But in terms of cost, to meet the fire grade requirements of plastic compared with ordinary plastic prices are very different. Power supply problem for LED lamps
Due to the low power factor, in the large area of LED lamps, it is easy to cause too large wire load and temperature rise, resulting in circuit safety.
Therefore, when choosing LED lamps and lanterns, we must pay special attention to not taking inferior LED lamps and lanterns home, cause our trouble, at the same time, also affect our health. How do we distinguish inferior LED lamps, do you recognize them?
LED product quality problems are numerous, the quality and low price of products have seriously affected the reputation of LED in the market, and become an obstacle to the popularization of LED lamps. In the vicious competition of LED market price competition, the listing of a large number of unqualified products has violated the real value of LED energy saving, long life, environmental protection, etc. How to distinguish the advantages and disadvantages of LED lamps should start from the following aspects:
low power factor, indicating that the use of drive power supply, and circuit design is not good, will greatly reduce the service life of lamps, power factor is low, the life of lamps will not be long;
Look at "lamp cooling conditions-material, structure":
LED lamps heat dissipation is also very important, the same power factor of lamps and the same quality of lamp beads, if the cooling condition is not good, lamp beads in high-temperature work, light decay will be very large, the life of lamps will be reduced;
Look at the "lamp bead quality":
The quality of the lamp beads depends on the chip quality and packaging technology;
Look at the drive power supply used by lamps:
the service life of the power supply is much shorter than other parts of the lamps, the life of the power supply affects the overall life of the lamps, the theoretical life of the lamp bead is 50,000-100,000 hours, and the life of the power supply is in 02,000-30,000 hours, the design of the power supply and material selection will determine the service life of the power supply;
Look at the light effect:
the same lamp bead power, the higher the light efficiency, the higher the brightness, the amse lighting brightness, the smaller the power consumption, the more energy saving;
Look at the power supply efficiency:
the higher the power supply efficiency, the better, the higher, indicating that the smaller the power consumption of the power supply itself, the greater the output power;
China's LED lamps safety standards have been issued, please choose LED lamps according to the national safety standards;
Whether the workmanship is fine.
A good quality LED lamps and lanterns, in addition to the above-mentioned several main aspects, but also according to different use environments, there are different technical requirements, such as moisture-proof, dustproof, anti-magnetism, lightning strike.
