There are many styles and forms of pixel LED strips in the market, but in general, they can be divided into SPI pixel LED strips and DMX512 pixel LED strips.
At the beginning, led pixel products were all DMX512 products, patented, and there was a special DMX software system to control the lights. The cost of equipment is high, and the number of people who can use the system is very rare, which greatly restricts the development of pixel products.
Later, based on the product performance of DMX512 light strips, some companies in the market have designed SPI signal products that have similar effects and can break the DMX512 patent limit, and the price is cheaper. Soon, SPI products became popular in the market.
Compared with DMX512 pixel led light strip, SPI pixel led light strip is cheaper and more popular in the market, and its styles are more diverse.
Divided by the position of the IC, SPI light strips can be divided into built-in IC pixel led strips and external IC pixel led strips.
Divided by voltage, it can be divided into 5V, 12V, 24V
According to whether there are 2 communication lines, it can be divided into breakpoint continue led strip and non-breakpoint continue led strip
Divided by the color of the light strip, it can be divided into white color, dual color, RGB, RGBW and RGBWW pixel led strips
According to the direction of the lamp beads, it can be divided into positive glowing magic light strip and side glowing magic light strip
In general, SPI can meet most of your functional requirements, so if there is no special requirement, you only need to choose the right one from the SPI magic light bar.
Of course, DMX512 pixel led strips also has incomparable advantages, which are mainly reflected in the following aspects:
1. The DMX512 led strip can be arranged by the address code and cooperate with the DMX512 system to achieve more complex functions and effects
2. DMX512 signal has higher data transmission frequency and stronger anti-interference, suitable for more high-end applications
3. DMX512 is a dual-signal transmission, and it has the function of resuming the transmission. The damage of a single IC will not affect the work of the entire light bar.
Therefore, compared to the SPI magic light bar, the DMX512 magic light bar is more high-end. If your project has higher requirements for quality and stability, or you want to achieve more complex control, it is recommended to use DMX512 magic light bar.
In general, SPI is more cost-effective and has many styles. It is better to use SPI signal light strips for conventional projects; DMX512 Symphony light strips have more stable performance and are more suitable for high-end projects.
