Full-color LED light strip: The so-called LED full-color light strip refers to the assembly of LED on the ribbon FPC flexible circuit board or PCB hard board, which is named because its product shape is like a strip. The full-color LED light strip and the mirror-color horse-racing light strip can control the changes of tricks such as single-light horse-racing, running water, window opening, meteor rear-end chasing and chasing. Any color can be displayed, and can be combined into any trick at will, especially used as a light bar screen.

Full color LED light strip

The full color LED light belt and the light source of the mirror-color racetrack light belt are rich and colorful, with high visibility and visual appeal. It is widely used in wall corridors, indoor environment decoration, entertainment places, bar backlight, ceiling backlight, LED light box light source, LED luminous signs, aquatic products, car decoration, etc. It is a new generation of lighting source that replaces traditional neon lights, fluorescent lights and tubes.

Full-color LED light belt is more and more popular with consumers because of its good features such as energy saving, multiple tricks, dazzling changing effects, high brightness, suitable price, wide application environment and simple installation. In the whole profession, everyone has different names or nomenclature about full-color light strips. The professional nomenclature is that full-color LED light strips are also called LED slide light strips.

Compared with the general light strip in the mall, this product has one more drive IC on the FPC board. There are certain specifications for its copper requirements in the process of making the board. If the copper is not used properly during the manufacturing process, it will seriously lead to the unstable condition of the product. Therefore, it is customary that the requirements for full-color LED light with 12V 30 light boards will be more than 2A copper on the double-sided board. 144 The lamp should be above 2.5A copper.

LED full-color light strip and LED full-color light strip are generally universal, both refer to flexible light strip; However, the slide light belt refers specifically to the flexible light belt, that is, the light belt using FPC as the circuit board. The light strip includes soft light strip and hard light strip. One is to use FPC as circuit board, and the other is to use hard board as circuit board. The general specification of applied voltage is DC 12V, and 24V voltage is also selected. There are also specially customized ones, which are available for 6V and 9V. The common lamp strip specification on the market is to select 12V voltage.

LED dazzle light - TF-S166

Here, we recommend a new LED dazzle lamp TF-S166, which is represented by Gongcai Electronics from Taiwan. TF-S166 is a dedicated output channel of 3-way RGB LED driver circuit. It also includes internal intelligent digital port data latch and signal shaping amplification drive circuit. TF-S166 uses single NZR communication mode. After the chip is powered on and reset, the DIN port receives data from the controller. The first IC collects the initial 24-bit data, and then sends it to the internal data latch. The other data is shaped by the internal signal shaping and amplification circuit, and then sent to the next cascade IC through the DO port. After each chip is transmitted, the signal is reduced by 24 bits. The IC adopts automatic shaping transmission technology, so that the number of chip cascades is not limited by signal transmission, but only depends on the speed of signal transmission.

The data locking of IC depends on the received 24-bit data in IO_ R、IO_ G、IO_ Port B generates different duty cycle signals. When the DIN port inputs a reset signal, all chips send the received data to each segment synchronously. After the reset signal ends, it will receive new data again. Before receiving a new reset signal, IO_ R、IO_ G、IO_ The control signal of port B remains unchanged. The IC sends the correctly received PWM data to IO_ R、IO_ G、IO_ Port B, after receiving the low voltage reset signal, the time shall be at least 24us.

In the field of full-color LED light strips, Taiwan Wanghong is one of the best. To learn more about the technical application of Taiwan's LED dazzle lights, please log in to the official website of Gongcai for consultation.
