General Description
OSTW5050C1A is a intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 components.
It internal include intelligent digital port data latch and signal reshaping amplification drive circuit.
Also include a precision internal oscillator and a 12V voltage programmable constant curre-nt control part, effectively ensuring the pixel point
light color height consistent.
The data transfer protocol use single NZR communication mode. After the pixel power-on reset, the DIN port receive data from controller, the
first pixel collect initial 24bit data then sent to the internal data latch, the other data which reshaping by the internal signal reshaping
amplification circuit sent to the next cascade pixel through the DO port.
After transmission for each pixel the signal to reduce 24bit. pixel adopt auto resha-ping transmit technology, making the pixel cascade number
is not limited the signal transmission, only depend on the speed of signal transmission. LED with low driving voltage, environmental
protection and energy saving, high brightness, scattering angle is large, good consistency, low power, long life and other advantages.
The control chip integrated in LED above becoming more simple circuit, small volume, convenient installation.

Storage
· Storage Conditions
Before opening the package:
The LEDs should be kept at 30°C or less and 60%RH or less. The LEDs should be used within a year. When storing the LEDs, moisture proof
packaging with absorbent material (silica gel) is recommended.
· After opening the package:
Soldering should be done right after opening the package (within 24hrs).
Keeping of a fraction, sealing and Temperature: 5~40 Humidity: Less than 30%.
If the package has been opened more than 1 week or the color of desiccant changes, components should be dried for 10-12hrs, at 60±3 .
· Optosupply LED electrode sections are comprised of a silver plated copper alloy. The silver surface may be affected by environments which
contain corrosive gases and so on. Please avoid conditions which may cause the LED to corrode, tarnish or discolor. This corrosion or
discoloration may cause difficulty during soldering operations. It is recommended that the User use the LEDs as soon as possible.
· Please avoid rapid transitions in ambient temperature, especially in high humidity environments where condensation can occur.
■
Soldering Heat Reliability:
Reflow soldering Profile
· Reflow soldering should not be done more than two times.
· When soldering, do not put stress on the LEDs during heating.
· After soldering, do not warp the circuit board.
· Repairing should not be done after the LEDs have been soldered. When repairing is unavoidable,
a double-head soldering iron should be used. It should be confirmed beforehand whether the
Characteristics of the LEDs will or will not be damaged by repairing.
