"Light-emitting diodes (leads) are semiconductor devices that emit light when an electric current is passed through them. Light is produced when particles carrying electric currents, called electrons and holes, combine in a semiconductor material. Essentially, leds are tiny beads of light that are easy to install into a circuit. But unlike incandescent bulbs, ucs2904b led strip light doesn't burn the filament, uses less power, and doesn't generate a lot of heat. They emit light only through the movement of electrons in a semiconductor material, and have a lifetime as lengthy as a standard transistor.
Leds last thousands of hours longer than incandescent bulbs. Because of these advantages, LED has become one of the most popular lighting technologies. It is mainly divided into three kinds: DIP LED, SMD LED and COB LED. Today, we will make a comparison between SMD and COB. First, look at the following picture to distinguish the two LED lights from their appearance:
1, SMD LED chip in a chip can have up to 3 diodes, each diode has a separate circuit. Each circuit has a cathode and an anode, resulting in two, four, or six contacts in the chip.
The chip can contain a red, green, and blue diode, and you can create any color by merely adjusting the output frequency.
A variety of sizes can support complex design chips.
SMD chips are known for their brightness, producing 50-100lm/w.
2. COB chips generally have 9 or more diodes. It also has 1 circuit and 2 contacts, but it does not depend on the number of diodes.
COB LED lights cannot be used to produce color-changing bulbs or lamps and need to be adjusted through multiple channels to produce a color-changing effect.
Since the leds of all the lamps are concentrated in one area, greater cooling capacity is required."
