With the development of science and technology, environmental protection and energy conservation has become a hot topic and LED lights have become a must-have for every household. But there are so many brands of LED lights in the market, how consumers can distinguish the quality of LED lights? Today we give you 5 ways to distinguish the high quality and low quality LED lights.
1. See product quality from packaging and trademarks.
The packaging of genuine LED lamps should have relevant information such as brand trademark, relevant certification mark, rated voltage, voltage range, rated power, etc., and the printing quality is good, the font is clear; the trademark printing quality of counterfeit products is poor, and the trademarks of some products can be wiped easily with a damp cloth.
2. Determine the pros and cons of the product from the appearance of the product.
Whether the combination of the lamp cap and the plastic part is tight. Whether the combination of the lamp tube and the plastic part of the lower case is firm. Whether the upper and lower shell plastic parts are in place. Whether the appropriate safety element or fuse is used in the electronic circuit.
3. Look at the light decay from the LED lamp bead chip.
The illuminator of the LED is a chip. The key of the LED chip is life. The life expectancy is determined by light decay. The quality of the chip determines the brightness and light decay of the lamp bead. The good lamp bead is not only bright and high but also has low light decay.
4. See product life from power quality.
A good LED lamp must be equipped with a high-quality driver power supply. The good power supply has good heat dissipation. The IC used is imported. The power factor of the power supply is basically above 0.9. There is an automatic protection function, which makes the LED lamp last longer.
5. Grasp the heat dissipation of the product from the temperature.
Let the lamp ignite for about 5 minutes, the temperature rise is not very fast, and the hand can be placed on the lamp housing for a long time, which proves that the heat dissipation is reasonable.
