With the progress of society and the development of the times, LED lights have gradually replaced the credit of incandescent lamps, and have become a necessity for indoor and outdoor lighting decoration. The necessary factors for people to choose it are also because of the small size, low power consumption, and long service life of LED lights, which are more in line with practical needs. However, LED lights are only a general term. They are divided into in-line LED lamp beads and SMD LED lamp beads in terms of structure, so how to distinguish in-line LED lamp beads and SMD LED lamp beads? Next, Guangmai Technology will analyze its structure, power, use and other aspects one by one:
Appearance: It can be divided into in-line and patch-in-line LED lamp beads, which are plug-in lamp beads like a hat, and SMD-type LED lamp beads are flat SMD lamp beads, in-line and patch-type lamp beads. The chip difference is as follows. In the case of using the same light-emitting chip, there is no difference between the two types.
Angle: The angle of direct insertion of the LED lamp beads is very small, which means that the light is relatively concentrated, and the range is very far, but the irradiation range is limited; while the general angle of the SMD LED lamp beads is very large, which means that the light is relatively scattered and illuminated. The range is wide, but the range is relatively short.
Process difference: DIP plug-in technology is used for direct insertion, while SMD technology is used for patch, and the grade is higher.
Power: In-line LED lamp bead power should be higher, while SMD LED lamp bead power should be lower.
Light-emitting principle: Direct plug-in LED lamp beads are used for discharge light, while SMD LED lamp beads are used for cold light emission.
Shock resistance: The shock resistance of the direct-plug LED lamp beads is not as good as that of the SMD LED lamp beads.
Light color: In-line LED lamp beads can emit red, orange, yellow, and green light in multiple colors, while SMD LED lamp beads do not have this ability.
Uses: In-line LED lamp beads are mainly used for Christmas lights, Great Wall light strips, ceiling lights, downlights, flashlights, small Lu lights, etc. SMD LED lamp beads are mainly used for soft and hard light strips, light strips, fluorescent tubes, corn Lamps, desk lamps.
Environmental protection function: In-line LED lamp beads do not have mercury, which is a harmful metal. In comparison, SMD LED lamp beads are not good enough in environmental protection.
