1 pin insertion (DIP)

This LED lamp bead is a simpler light -emitting diode, because there are two filaments like "feet" under the lamp bead, which can be directly put on the circuit board, so it is called a pins inserted lamp bead. It has good safety and stable performance. It can glow in the case of low voltage, and it can also be lit with low loss, high efficiency, and long life.

Common shape:

This kind of lamps can have a variety of shapes, such as circular, oval, square, and even alien. Although it looks roughly, the shape and size are not much different, but the cross section of different shapes of lamp beads is different.

Lighting type:

If you carefully observe different lamp beads, you will find that the number of "pin" of some lamp beads is different. These "pin" can make the light -emitting diode generated different colors of light.

Application field:

In the field of lighting, inserted lamp beads are hardly used in pins; generally used as car lights, indicators, display screens, etc.

Little power surface paste (SMD)

This light bead source is welded on the surface of the circuit board instead of crossing the circuit board. It is small, and some are even smaller than the lamp beads inserted into the pin.

Common models:

There are many models of this type of lamp beads, which are 2835 (PCT), 4014, 3528, 3014, etc. The first two of each model indicate the wide "X.X mm", and the latter two indicate "x.x mm". Essence For example, 2835 represents 2.8 mm wide and 3.5 mm long.

The surface is painted with yellow fluorescent powder, which emits white light.

Application field:

The use range of this type of small -power gauge lamp beads is very wide. Because it is small, it can be used anywhere, so it can be pasted in various LED lights, and the number can be adjusted and changed according to the needs.

Uther power surface paste type

The third lamp bead is also a table sticker. It is essentially similar to the small power table, but the high power and volume are larger; in the fine structure, there is a lens that can better gather the light on the light in Together.
