LED lamp beads are actually light-emitting diodes. At present, a type of decorative lighting products often used in the commercial and home lighting industry not only have the effect of lighting, but because the light is relatively soft, they are used for interior decoration and can adjust people to a certain extent. People’s mood is relieved, and because the types and types of LED lamp beads on the market are very diverse, what details should consumers pay attention to during the purchase process?
1. The brightness of LED lamp beads
Different colors of LED lamp beads will have different luminous intensities, and the common units are mcd and lm, that is, millicandela. The higher the value, the greater the luminous intensity, that is, the brighter. This is an important indicator for selecting LED lamps. The higher the brightness requirement, the more expensive the lamp is. This is because high-brightness LED chips are more expensive.
2. The color of the LED
There are many small packaging factories that do not have a spectroscopy and color separation machine, so it is difficult to guarantee the quality. LEDs that have not undergone color separation have poor color consistency, and of course the price difference is relatively large.
3. LED chip
The chip origin determines the price and the quality of the lamp. Customers can often determine the quality of the LED lamp by understanding the LED chip supplier used in the LED lamp, because the biggest factor in determining the price of the LED is the chip. Therefore, knowing the chip supplier can roughly determine the price range of LED lights, which is one of the effective methods for experienced buyers to evaluate suppliers.
4. LED package
The encapsulation of LED lamp beads is divided into resin encapsulation and silicone encapsulation. The price of the resin package is cheaper, because the heat dissipation performance is slightly worse, and the others are the same. Silicone encapsulation has good heat dissipation performance, so the price is slightly more expensive than resin encapsulation.
5. Service life
Although the lifespan of LEDs is 80,000 to 100,000 hours, because LEDs are constant current components, the constant current effects of LED lights produced by different manufacturers are different, and of course the lifespan is different.
