LED display module

What are the three types of LEDs?

Different from the process of LED screen surface treatment, we can divide it into plug -in modules, table stickers

1. Plug -in module-DIP (Used for outdoor)
It refers to the DIP packaging lights through the PCB board and filled the tin into the light hole by welding. The LED module made of this process is the lamp module; Okay; the disadvantage is that the pixel density is small.

2、Second, table sticker module-SMD (Used for indoor)
The table sticker is also called SMT. The lamp encapsulated SMT packaging is welded on the surface of the PCB board through the welding process. The lights do not need to pass through the PCB board. The advantages are: large perspectives, the graphics are soft, the pixel density is large, suitable for indoor viewing; the disadvantage is that the disadvantage is that the disadvantage is The brightness is not high enough, and the light tube itself is not good enough..

Advantages：

1. Energy -saving:
A few degrees a few degrees of electricity for a thousand hours (the ordinary 60W incandescent lamp is consuming 1 degree at 17 hours, and the ordinary 10W energy -saving lamp is consumed by 1 degree per hour)
2. Super long life:
Semiconductor chips are glowing, no light wire, no glass bubbles, not afraid of vibration, not easy to break, the service life can reach 50,000 hours (the service life of ordinary incandescent lamps is only 1,000 hours, and the service life of ordinary energy -saving lamps is only 8,000 hours)
3. High brightness, small heat calories:
90%of the electrical energy can be converted into visible light (80%of the electrical energy of 80%of ordinary incandescent lamps into heat energy, and only 20%of electrical energy is converted into optical energy).
4. Green environmental protection:
No harmful elements such as mercury and crickets are conducive to recycling. The light does not contain ultraviolet and infrared rays, and does not produce radiation (ordinary lights contain ultraviolet and infrared rays)
5. High safety factor:
The required voltage and current are small, the heat is small, no safety hazards occur, in dangerous places such as mines
6. Great market potential:
Low -voltage, DC power supply, battery and solar power supply, in remote mountainous areas and field lighting, etc.
