Luminous flux is the total luminous flux output as measured with an integrating sphere. 2. Iv (flux v) classification code is marked on each packing bag. 3. The chromaticity coordinates (x, y) is derived from the 1931 CIE chromaticity diagram. 4. Caution in ESD: Static Electricity and surge damages the LED. It is recommended using a wrist band or anti-electrostatic glove when handling the LED. All devices, equipment and machinery must be properly grounded. 5. CAS140B is the test standard for the chromaticity coordinates (x, y) & v. 6. The chromaticity coordinates (x, y) guarantee should be added +/- 0.01 tolerances 7. CRI measurement allowance is 5 8.

All temperatures refer to topside of the package, measured on the package body surface. 3. The soldering condition referring to J-STD-020. The storage ambient for the LEDs should not exceed 30 C temperature or 70% relative humidity. It is recommended that LEDs out of their original packaging are soldered within one week. For extended storage out of their original packaging, it is recommended that the LEDs were stored in a sealed container with appropriate desiccant, or desiccators with nitrogen ambient. If the LEDs were unpacked more than 168hrs, baking the LEDs at 60 for 60 mins before soldering process. 4. The soldering profile could be further referred to different soldering grease material characteristic. The grease vendor will provide this information. 5. A rapid-rate process is not recommended for the LEDs cooling down from the peak temperature. 6. Although the recommended reflow conditions are specified above, the reflow or hand soldering condition at the lowest possible temperature is desirable for the LEDs. 7. LiteOn cannot make a guarantee on the LEDs which have been already assembled using the dip soldering method. 018 BNC-OD-C131/A4 Created Date: 03/01/2013 Revision: 16, 06/06/2014 LED Middle POWER K140SZRxx Series 8.

Cautions 10.1 Application The LEDs described here are intended to be used for ordinary electronic equipment (such as office equipment, communication equipment and household applications).Consult Liteon's Sales in advance for information on applications in which exceptional reliability is required, particularly when the failure or malfunction of the LEDs may directly jeopardize life or health (such as in aviation, transportation, traffic control equipment, medical and life support systems and safety devices). 10.2 Storage This product is qualified as Moisture sensitive Level 3 per JEDEC J-STD-020 Precaution when handing this moisture sensitive product is important to ensure the reliability of the product. The package is sealed: The LEDs should be stored at 30C or less and 90%RH or less. And the LEDs are limited to use within one year, while the LEDs is packed in moisture-proof package with the desiccants inside. The package is opened: The LEDs should be stored at 30C or less and 60%RH or less. Moreover, the LEDs are limited to solder process within 168hrs. If the Humidity Indicator shows the pink color in 10% even higher or exceed the storage limiting time since opened, that we recommended to baking LEDs at 60C at least 24hrs. To seal the remainder LEDs return to package, it's recommended to be with workable desiccants in original package. 10.3 Cleaning Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED if necessary. 10.4 Drive Mode An LED is a current-operated device. In order to ensure intensity uniformity on multiple LEDs connected in parallel in an application, it is recommended that a current limiting resistor be incorporated in the drive circuit, in series with each LED as shown in Circuit A below Circuit model A Circuit model B 023 BNC-OD-C131/A4 Created Date: 03/01/2013 Revision: 16, 06/06/2014 LED Middle POWER K140SZRxx Series (A) Recommended circuit. (B) The brightness of each LED might appear different due to the differences in the I-V characteristics of those LEDs. 10.5 ESD (Electrostatic Discharge) Static Electricity or power surge will damage the LED. Suggestions to prevent ESD damage: Use of a conductive wrist band or anti-electrostatic glove when handling these LEDs. All devices, equipment, and machinery must be properly grounded. Work tables, storage racks, etc. should be properly grounded. Use ion blower to neutralize the static charge which might have built up on surface of the LED's plastic lens as a result of friction between LEDs during storage and handling. ESD-damaged LEDs will exhibit abnormal characteristics such as high reverse leakage current, low forward voltage, or "no lightup" at low currents.To verify for ESD damage, check for "light up" and Vf of the suspect LEDs at low currents.The Vf of "good" LEDs should be >2.0V@0.1mA for InGaN product and >1.4V@0.1mA for AlInGaP product. 10.6 Suggested Checking List: Training and Certification 1. Everyone working in a static-safe area is ESD-certified? 2. Training records kept and re-certification dates monitored? Static-Safe Workstation & Work Areas 1. Static-safe workstation or work-areas have ESD signs? 2. All surfaces and objects at all static-safe workstation and within 1 ft measure less than 100V? 3.

Garments, hairs or anything closer than 1 ft to ESD items measure less than 100V*? 4. Every wrist strap or heel strap/conductive shoes checked daily and result recorded for all DLs? 5. All wrist strap or heel strap checkers calibration up to date? Note: *50V for Blue LED. Device Handling 1. Every ESDS items identified by EIA-471 labels on item or packaging? 2. All ESDS items completely inside properly closed static-shielding containers when not at static-safe workstation? 3. No static charge generators (e.g. plastics) inside shielding containers with ESDS items? 4. All flexible conductive and dissipative package materials inspected before reuse or recycle? Others 1. Audit result reported to entity ESD control coordinator? 2. Corrective action from previous audits completed? 3. Are audit records complete and on file? 10.7 Others: Do not put any pressure on the light emitting surface either by finger or any hand tool and do not stack the products. Stress or pressure may cause damage to the wires of the LED array.
