For this article, we give you a comprehensive and simplistic explanation of how each LED technology model and its “LED packaging” differ from one another.
This article will guide you in choosing the right LED technology suitable for your commercial or residential space needs.
A. What Is DIP LED Technology?
DIP LED, which stands for Dual In-Line Package LEDs, is considered the standard LED technology version.
Even though it is considered the oldest form of LED technology, it is far from obsolete. DIP LEDs are still widely used today for many signages and digital displays because of their durability and high performance.
It is easy to recognize a DIP LED because of its distinct structure. It has a cylindrical body and a spherical top and has the same shape as the bullet.
Each DIP LED has a single chip and semiconductor die that emits light when supplied with electricity. The LED chip is encased with a hard-plastic epoxy lens or case and two (2) connecting pins for easy soldering to any LED circuit or LED board.
Each DIP LED is only capable of producing one color. That is why it is commonly combined with the other two differently colored DIP LEDs to achieve the RGB (red, green, blue) color scheme.
This type of LED produces around 4 lumens per single LED, and the input power is 5 volts to 12 volts.
B. What Are The Unique Features Of DIP LED?
Durable Hard Casing. One of the most sought features of DIP LED is its resistance to impacts. This LED light has durable encapsulation that protects its interior components from blows and mil collisions. Additionally, the LEDs also integrate into LED modules, which gives them extra resistance and strength.
Energy Saving. DIP LED can help you save energy by up to 80% compared to traditional lights like fluorescent bulbs. While it helps save you money, it does not compromise the brightness it provides. The beam angle of the DIP LED reaches 60 degrees.
Different Color Options. DIP LEDs can produce various colors like red, blue, green. You could also choose from warm white to pure white lights.
