What are the types of LED light strips?
According to the type of SMD lamp beads:
LED light strips are generally composed of PCB substrate (flexible or hard board), LED lamp beads, and other accessories. The core part is LED lamp beads, generally SMD patch lamp beads are the main ones.
Regular models can generally be divided into the following 6 types:
(1) SMD5050 led light strip
5050 is the earliest lamp bead packaging form that appeared. The initial power was very low, usually 0.1-0.2W. However, with the development of technology, there are already 1W-3W SMD5050 light strips.
Moreover, because the 5050 lamp bead is large in size and has many color changes, it can be made into RGB, RGB+W, RGB+CCT; there are also many kinds of control ICs that are also packaged in the lamp bead. Generally, the 5050 lamp bead has 6 solder joints. Pads, if a control IC is added, some may have as many as 8 pads.
(2) SMD3528 led light strip
3528 appears after 5050 and is the elder brother of 3014 and 2835. Its size is larger than that of 2835, and its power is similar to that of 3014. With the widespread use of 2835, the cost performance of 3528 lamp beads is no longer advantageous, and it is slowly withdrawing from the market.
(3) SMD3014 led light strip
3014 appeared earlier than 2835, with low power, generally only 0.1W, and small size and light-emitting surface. It was first used in backlights and has the advantage of small size. When used on a light strip, it cannot compare to 2835 in terms of brightness or luminous surface.
(4) SMD2835 led light strip
2835 is the most widely used and mature packaging form besides 5050. Power ranges from 0.1W to 1W, widely used in various indoor lighting fixtures, LED light strips, outdoor lighting fixtures, etc.
The 2835 package generally only has two pads, positive and negative, and are mostly used with single-color temperature lamp beads. Generally, dual color temperature or RGB cannot be done. However, it has stable performance, good heat dissipation and high luminous efficiency. It is the most common type of light strip.
(5) SMD5730/5630 led light strip
5730 or similar 5630 is actually the same package type. This type of light-emitting surface is large and the power is also large, usually 0.5-1W per piece. If used on a light strip, the power of a single lamp bead will be too high, and the power and brightness of the entire light strip will be too high. Of course, the cost is also high. Therefore, they are generally not used much, and are commonly found on high-voltage 220v light strips.
(6)COB light strip
COB means chips on board, which means that the light-emitting chip is placed directly on the PCB, without the need for gold wires and brackets. A layer of phosphor is cast on the surface. This is a relatively new light strip product with the advantages of high brightness, uniform light strips and no graininess. Moreover, it is more tensile-resistant than ordinary SMD light strips. With the development and popularization of applications and lighting markets, COB light strips will become the mainstream of LED light strips in the future.
