In-line LED, also known as plug-in LED, the main specifications are: straw hat/helmet, round head, concave, oval, square (2*3*4) bullet head, flat head, (3/5/flat head/bread type) Piranhas etc. According to the size, it can be divided into 2mm, 3mm, 4mm, 5mm, 8mm, 10mm and so on.

SMD is the SMD LED, which is generally divided into front-side lighting (such as 3020/3528/5050, etc.) 020/1016/1024, etc. These are side-emitting light sources. Compared with plug-in LEDs, SMD LED lamp beads are smaller and have a wider range of applications.

High-power LEDs cannot be classified into SMD chip series, their power and current usage are different, and the photoelectric parameters are very different. If a single high-power LED light source does not have a heat dissipation base (usually a hexagonal aluminum base), its appearance is not much different from that of ordinary patches. However, it is essentially different from SMD patches in terms of use conditions/environments/effects.

A brief introduction to LED lamp beads, let's talk about the prospects of LED lamp beads. The full name of LED lamp beads is called semiconductor light-emitting diodes. Semiconductor light-emitting devices; LED lamp beads are mainly characterized by low power consumption, high brightness, bright colors, anti-vibration, long life (80,000-100,000 hours of normal light), cold light sources, etc., realizing the real "green lighting". As a new light source, LED lighting products will inevitably replace white woven lamps in the future of the 21st century and become another revolution in human lighting. Why is it said that LED lamp beads will inevitably replace white woven lamps? The LED lamp beads are very small in size, and each unit LED chip is 3-5mm square, so it can be prepared into various shapes of devices and is suitable for variable environments. There is also stability, which can continuously emit light for 100,000 hours, and the light decay is 50% of the initial value.
