Handling with care for this product -Both the light emitting area and white rim around the light emitting area is composed of resin materials. Please avoid the resin area from being pressed, stressed, rubbed, come into contact with sharp metal nail (e.g. edge of reflector part) because the function, performance and reliability of this product are negatively impacted. -Please be aware that this product should not come into contact with any other parts while incorporating in your lighting apparatus or your other products. -Please be aware that careful handling is required after the attachment of lead wires to prevent the application of any load to the connections. -For more information, please refer to application note "Instruction Manual(COB LED Package)". 7-2. Countermeasure against static electricity -Handling of this product needs countermeasures against static electricity because this is a semiconductor product. -Please take adequate measures to prevent any static electricity being produced such as the wearing of a wristband or anti-static gloves when handling this product. -Every manufacturing facility in regard to the product (plant, equipment, machine, carrier machine and conveyance unit) should be connected to ground and please avoid the product to be electric-charged. -ESD sensitivity of this product is over 1000V (HBM, based on JEITA ED-4701/304). -After assembling the LEDs into your final product(s), it is recommended to check whether the assembled LEDs are damaged by static electricity (electrical leak phenomenon) or not. -It is easy to find static damaged LED dies by a light-on test with the minimum current value. 7-3. Caution of product assembly -Regarding this product assembling on the heat sink, it is recommended to use M3 screw. It might be good for screw tightening on the heat sink to do temporary tightening and final tightening. In addition, please don’t press with excess stress on the product. -The condition of the product assembling on the heat sink and the control of screw tightening torque needs to be optimized according to the specification of the heat sink. -Roughness, unevenness and burr of surface negatively impact thermal bonding between the product and heat sink and increase heat thermal resistance between them. Confidence of thermally and mechanical coupling between the product and heat sink are confirmed by checking the mounting surface and measuring the case temperature of the product. -In order to reduce the thermal resistance at assembly, it might be good to use TIM (Thermal Interface Material) on whole contact surface of the product. In case of using thermal grease for the TIM, it might be good to apply uniformly on the contact surface of the product. In case of using thermal sheet for the TIM, it might be good to make sure that the product is NOT strained by stress when the screws are tightened for assembly. -For more information, please refer to application note "Instruction Manual(COB LED Package)". 11 Ref.CE-0174P-201801 7-4. Thermal Design -The thermal design to draw heat away from the LED junction is most critical parameter for an LED illumination system. High operating temperatures at the LED junction adversely affect the performance of LED’s light output and lifetime. Therefore the LED junction temperature should not exceed the absolute maximum rating in LED illumination system. -The LED junction temperature while operation of LED illumination system depends upon thermal resistance of internal LED package (Rj-c), outer thermal resistances of LED package, power loss and ambient temperature. Please take both of the thermal design specifications and ambient temperature conditions into consideration for the setting of driving conditions. -For more information, please refer to application note "Thermal Management", "Instruction Manual(COB LED Package)". 7-5. Driving Current -A constant current is recommended as an applying driving current to this product. In the case of constant voltage driving, please connect current-limiting resistor to each products in series and control the driving current to keep under the absolute maximum rating forward current value. -Electrical transient might apply excess voltage, excess current and reverse voltage to the product(s). They also affect negative impact on the product(s) therefore please make sure that no excess voltage, no excess current and no reverse voltage is applied to the product(s) when the LED driver is turn-on and/or turn-off. -For more information, please refer to application note "Driving", "Instruction Manual(COB LED Package)". 7-6.

Electrical Safety -This product is designed and produced according to IEC 62031:2008 (IEC 62031:2008 LED modules for general lighting. Safety specification) -Dielectric voltage withstand test has been conducted on this product to see any failure after applying voltage between active pads and aluminum section of the product, and to pass at least 500V. -Considering conformity assessment for IEC62031:2008, almost all items of the specification depend upon your final product of LED illumination system. Therefore, please confirm with your final product for electrical safety of your product. As well, the products comply with the criteria of IEC62031:2008 as single LED package. 12 Ref.CE-0174P-201801 7-8. Recommended soldering Condition (This product is not adaptable to reflow process.) -For manual soldering Please use lead-free soldering. Soldering shall be implemented using a soldering bit at a temperature lower than 350C, and shall be finished within 3.5 seconds for one land. No external force shall be applied to resin part while soldering is implemented. Next process of soldering should be carried out after the product has return to ambient temperature. Contacts number of soldering bit should be within twice for each terminal. * Citizen Electronics cannot guarantee if usage exceeds these recommended conditions. Please use it after sufficient verification is carried out on your own risk if absolutely necessary. -For more information, please refer to application note "Instruction Manual(COB LED Package)". 7-9. Eye Safety -The International Electrical Commission (IEC) published in 2006 IEC 62471 ”2006 Photobiological safety of lamps and lamp systems ” which includes LEDs within its scope. When sorting single LEDs according to IEC 62471, almost all white LEDs can be classified as belonging to either Exempt Group (no hazard) or Risk Group 1 (low risk). -However, Optical characteristics of LEDs such as radiant flux, spectrum and light distribution are factors that affect the risk group determination of the LED, and especially a high-power LED, that emits light containing blue wavelengths, might have properties equivalent to those of Risk Group 2 (moderate risk). -Great care should be taken when directly viewing an LED that is driven at high current, has multiple uses as a module or when focusing the light with optical instruments, as these actions might greatly increase the hazard to your eyes. -It is recommended to regard the evaluation of stand-alone LED packages as a reference and to evaluate your final product. 7-10. This product is not designed for usage under the following conditions. If the product might be used under the following conditions, you shall evaluate its effect and appropriate them. In places where the product might: -directly and indirectly get wet due to rain and/or at place with the fear. -be damage by seawater and/or at place with the fear -be exposed to corrosive gas (such as Cl2, H2S, NH3, SOx, NOx and so on) and/or at place with the fear. -be exposed to dust, fluid or oil and/or at place with the fear. 13 Ref.CE-0174P-201801 Precautions with regard to product use (1) This document is provided for reference purposes only so that CITIZEN ELECTRONICS' products are used as intended.
