1 product overview:
XT151RGBXP8-XX is a set of intelligent control circuit and the light emitting circuit in one of the LED light source control. The appearance of a 5050LED lamp, each element is a pixel. Inside the pixel dot contains has intelligent digital interface data latch signal shaping amplification driving circuit, voltage stabilizing circuit of a power supply, a built-in constant current circuit, high precision RC oscillator output drive uses a patented PWM technology, effectively guarantee the pixel has in light of high color consistency.
Protocol data using unipolar return to zero code communication method, the pixel points after power on reset, end DIN received from the control data transmission over, first send 32bit data is the first pixel extraction, data sent to the pixels in the lock latch, the remaining number according to after internal plastic processing circuit shaping amplification by dissolved oxygen (do) the port started forward output to a cascade of pixels, each passing through a pixel, signal reduction 32bit. Pixels with automatic shaping forwarding technology, the cascade of the pixel number no signal transmission limit, limited only by the signal transmission speed).
Led with low driving voltage, energy saving and environmental protection, highly, scattering angle large, good consistency, ultra low power rate, ultra long life and other advantages. The control circuit is integrated in the LED above, circuit becomes more simple, small size, convenience installation more simple.
2 main application areas:
The full-color LED string light, LED full color module, LED super hard and soft lights, LED guardrail tube, LED appearance / scene lighting
The LED point source, LED pixel screen, LED shaped screen, a variety of electronic products, electrical equipment etc..
The replacement for SOP8 external IC; the product can realize the light, do not see other components;
3 characteristic description:
Top - SMD integrated high quality external control line serial cascade constant current IC;
] structure and sop8 package form, control circuit and chip integration in SMD 5050 components that constitute a complete external control pixel, color temperature effect fruit is uniform and consistent.
] built in data shaping circuit, a pixel signal is received after wave shaping and output, guarantee line road waveform distortion not will be carried over.
The built-in power on reset and reset circuit, the power does not work;
The gray level adjusting circuit (256 level adjustable),
The red drive special processing, color balance,
The single data transmission, infinite cascade.
The plastic forward strengthening technology, transmission distance between two points is more than 10M.
The data transmission frequency up to 800Kbps, when the refresh rate of 30 frames per second, the number of cascade is less than 1024.
