The public board with single-wire control 256 high gray constant current LED driver IC WS2811 as the core, the line is simple, stable performance, reliable quality and stable performance of the entire IC to ensure the stability of the PCB, while ensuring high precision constant current Light color and brightness consistency of product characteristics: In the case of fully meet the performance and stability, the board will reduce the number of components to a minimum the number of the most reasonable, not only cost savings but also due to the reduction of components in the product generation Among defect rate greatly reduced, thus greatly improving the production efficiency of customers. The public board with 3-wire connection, not only to save costs, improve efficiency, but also to facilitate the connection of customers. Advantages: 1. joints: We employ a three and signal transmission with a two-pair connectors and power supply to plug design; traditional light bar will generally use a two or three and plug the power cord and add two way design , two power cords used in the test, when lit or accidentally, it will short-circuit, causing light does not shine light bar, light bar causing severe burn entire pad 2. Design: We used rectangular oval and back surfaces of the pad design, enabling customers to freely cut links; traditional light bar design commonly used small round pad, the pad is small and round, even then carefully cut, can not re-welded. Some other pads are positive there is no pad on the back too inconvenient link, and our board all home plate inside the advantages of a design, customers do not need to worry about these aspects entirely composed of 3 parts: we using the currently most popular driver IC-WS2811-driven, highlighting stable 5050RGB lamp beads as light source; traditional light bar on the market in general will need to use some of the little-known cheap IC do drive, some secondary spectral lamp beads as light source , completely unable to guarantee product quality light bar, and we have our full confidence in the choice of materials. . . Size parameters: Driver IC: WS2811 emitting source: 5050RGB lamp beads pixels / m: 10 pixels (10) each three lamp beads Working voltage: 12V Power: 9-10W per meter waterproof rating: not waterproof Package: aluminum foil bag Product selling point: 1. The main: price, the market just started a full strip lights at least have twenty dollars, but we only need 15 yuan / m, why we can do so cheaper, because we are factory direct sales, sales of our own production of their shortened intermediate traders difference, so the price advantage can do others can not. 2. blackboard, the most common on the market are generally white light strip, strip Marquee is mostly white, why choose white, because white reflective, open up brighter. That parents who will ask, what are the advantages of your black, I'll tell pro, black, looks deep, easier integration with the surrounding black floor environment, it looks like a light where light, not disrupted due to the choice of luminous reflective sort 3. Materials: Our materials are carefully selected, proofing aging test, then the long-term assessment of suppliers was chosen, so the absolute guarantee of product quality installation: Power + controller + Light 1. First look for direction: on each light bar has a small arrow, the arrow as an output, a signal indicating the forward pass; tail of the arrow direction input signal for us to link wiring direction; 2. Each volume light strip inputs (that is, the front light bar on the tail of the arrow direction) has a three-color (red, green and white) of the plug connector with a two-color (red and white) of the plug connector ; tricolor connectors (red, green and white) access control: Red - positive vacancy is not connected (or connected to the power supply + 5V power supply positive) Green - signal output port connected to the controller above is usually: DATA white - above ground access controller ground terminal (ie 5V negative) is usually: GND or two colors COM connector (red and white) then the power: Red - positive 5V power transformer is usually above the positive: + V White - negative 5V power transformer is usually above the negative: -V or COM
