Everything you should know about LED Chips

Light-Emitting Diode (LED) is a semiconductor device that emits light when a current passes through it. When particles carrying electrical current (called electrons and holes) are combined within a semiconductor material, light is produced. Basically, LEDs are small lamp beads, which are easy to install into the circuit. But unlike incandescent lamps, it does not burn filaments, consumes less electricity, and does not generate a lot of heat. They are illuminated only by the movement of electrons in semiconductor materials and have a lifetime as long as standard transistors. The service life of LEDs is thousands of hours longer than that of incandescent bulbs. Because of these advantages, LEDs are one of the most popular technologies for lighting lamps. It is mainly divided into three types, DIP LED, SMD LED, COB LED.

Dual In-Line Package (DIP) LEDs

Dual-in-line package (DIP) LED, which the chip inside a hard plastic bulbous head, with 2 straight parallel connecting pins. Although some products still use this design today, its light attenuation and CRI are low, but its efficiency is far less than that of new LED chips. Today, more advanced LED chip styles are available for home, commercial, and industrial use.

Chip-on-Board (COB) LED Design

Chip-on-board (COB) refers to sticking several chips (usually 9 or more) on an aluminum substrate and packaging them together as a lighting module. This design takes up less space and provides maximum light potential. This technology eliminates the concept of brackets, no electroplating, no-reflow soldering, and no placement process, so the process is reduced by nearly one third and the cost is also saved by one third. You will see them used in loading docks, factories, warehouses, delivery areas, and other industrial applications. COB lights often appear in high-output downlights and track lights. They are also used for street lights, parking lots, and outdoor facilities that require large areas of lighting.

Surface Mounted Device (SMD) LED Chips

Surface Mounted Device (SMD) LED Chips is the next major development after DIP. Compared with traditional LEDs, the light output generated by SMD is much higher and consumes less power. Compared with DIP LED they have a smaller, flatter design, longer service life, reduced energy consumption by up to 75 percent , and lower maintenance costs.
