Technical Data Sheet,INTEGRATED LIGHT SOURCE INTELLIGENT CONTROL. OF CHIP ON TOP SMD TYPE LED,Model SK6812,1 Product Overview. SK6812 is a smart LED control circuit and light emitting circuit in one controlled LED source which. has the shape of a 5050 LED chip Each lighting element is a pixel and the intensities of the pixels are. contained within the intelligent digital interface input The output is driven by patented PWM. technology which effectively guarantees high consistency of the color of the pixels The control. circuit consists of a signal shaping amplification circuit a built in constant current circuit and a high. precision RC oscillator, The data protocol being used is unipolar NRZ communication mode The 24 bit data is transmitted. from the controller to DIN of the first element and if it is accepted it is extracted pixel to pixel After an. internal data latch the remaining data is passed through the internal amplification circuit and sent out. on the DO port to the remaining pixels The pixel is reset after the end of DIN Using automatic. shaping forwarding technology makes the number of cascaded pixels without signal transmission only. limited by signal transmission speed, The LED has a low driving voltage which allows for environmental protection and energy saving. high brightness scattering angle good consistency low power and long life The control circuit is. integrated in the LED above,2 Main Application Field.

Technical Data Sheet,TOP SMD LED Application Notes. 1 Features, The Purposes of making LEDCOLOR s customers and users to have a clear understanding on the ways how to. use the LED,2 Description, Generally The LED can be used the same way as other general purposed semiconductors When using. LEDCOLOR s TOP SMD LED the following precautions must be taken to protect the LED. 3 Cautions,3 1 Dust Cleaning, This emitter has a silicone surface There are many benefits to the silicone surface in terms of optical. properties and improved reliability However silicone is a softer material and prone to attract dust While a. minimal amount of dust and debris on the LED will not cause significant reduction in illumination steps. should be taken to keep the emitter free of dust, These include keeping the LEDs in the manufacturer s package prior to assembly and storing assemblies in.
an enclosed area after installing the emitters, Surface condition of this device may change when organic solvents such as trichloroethylene or acetone. were applied, Avoid using organic solvent it is recommended that isopropyl be used as a solvent for cleaning the LEDs. When using other solvents it should be confirmed beforehand whether the solvents will dissolve the. package and the resin of not, Do not clean the LEDs by the ultrasonic When it is absolutely necessary the influence as ultrasonic. cleaning on the LEDs depends on factors such as ultrasonic power Baking time and assembled condition. Before cleaning a pre test should be done to confirm whether any damage to the LEDs will occur. 3 2 Moisture Proof Package, In order to avoid the absorption of moisture during transportation and storage LED are packed in the. aluminum envelop A desiccant is included in the aluminum envelop as it absorbs moisture When. moisture is absorbed into the AMT package it may vaporize and expand during soldering There is a. possibility that this can cause exfoliation of the contacts and damage to the optical characteristics of the. LEDs For this reason the moisture proof package is used to keep moisture to a minimum in the package. 3 3 Storage, In order to avoid the absorption of moisture It is recommended to store SMD LED in bulk or taped in the.
dry box or the desiccator with a desiccant Otherwise to store them in the following environment as. recommended,a Temperature 5 30 b Humidity 60 RH Max. It is recommended to solder the LED as soon as possible after unpacking the aluminum envelop But in case. that the LED have to be left unused after unpacking envelop again is requested. The LED should be soldering within 1 hours after opening the package. If baking is required A baking treatment should be performed as follows. 70 5 for more than 24 hours,9 12 Document No SPC SK6812 Rev No 03. www szledcolor com,Technical Data Sheet,3 4 Reflow Soldering Characteristics. In testing LEDCOLOR has found S50 LEDs to be compatible with JEDEC J STD 020C using the parameters listed below As a. general guideline LEDCOLOR recommends that users follow the recommended soldering profile provided by the manufacturer. of solder paste used, Note that this general guideline is offered as a starting point and may require adjustment for certain PCB designs and. Configurations of reflow soldering equipment,C ritical Zone T L to T P.

Technical Data Sheet,3 5 Heat Generation, Thermal design of the end product is of paramount importance Please consider the heat generation of the. LED when making the system design The coefficient of temperature increase per input electric power is. affected by the thermal resistance of the circuit board and density of LED placement on the board as well as. components It is necessary to avoid in tense heat generation and operate within the maximum rating given in. this specification The operating current should be decided after considering the ambient maximum. temperature of LEDs,3 6 Electrostatic Discharge Surge Current. Electrostatic discharge ESD or surge current EOS may damage LED. Precautions such as ESD wrist strap ESD shoe strap or antistatic gloves must be worn whenever handling of. All devices equipment and machinery must be properly grounded. It is recommended to perform electrical test to screen out ESD failures at final inspection. It is important to eliminate the possibility of surge current during circuitry design. 3 7 Moisture Proof Package, Cannot take any responsibility for any trouble that are caused by using the LEDs at conditions exceeding. our specifications, The LED light output is strong enough to injure human eyes Precautions must be taken to prevent looking.
directly at the LEDs with unaided eyes for more than a few seconds. The formal specification must be exchanged and signed by both parties before large volume purchase begins. The appearance and specifications of the product may be modified for improvement without notice. 11 12 Document No SPC SK6812 Rev No 03,www szledcolor com.
