(2) directions for use when designing a circuit, the current through each led must not exceed the absolute maximum rating. operating at a constant current per led is recommended. in case of operating at a constant vo ltage, circuit b is recommended. if the leds are operated with constant voltage using circuit a, the current through the leds may vary due to the v ariation in forward voltage characteristics of the leds. (a) ... (b) ... this product should be operated using forward current. ensure that the product is not subjected to either forward or reverse voltage while it is not in use. in particular, subjecting it to continuous reverse voltage may cause migration, which may cause damage to the led die. when used in displays that are not used for a lon g time, the main power supply should be switched off for safety. it is recommended to operate the leds at a current greater than 10% of the sorting current to stabilize the led char acteristics. ensure that excessive voltages such as lightning surges are not applied to the leds. for outdoor use, necessary measures should be taken to pr event water, moisture and salt air damage.
nichia sts-da1-3082c 15 (3) handling precautions do not handle the leds with bare hands as it will contaminate the led surface and may affect the o ptical characteristics: it might cause the led to be deformed and/or the wire to break, which will cause the led not to illuminate . when handling the product with tweezers, be careful not to apply excessive force to the resin. otherwise, the resin can be cut, chipped, delaminate or deformed, causing wire-bond breaks and catastrophic failures. dropping the product may cause damage. do not stack assembled pcbs together. failure to comply can cause the resin portion of the product to be cut, chipped, delaminated and/or deformed. it may cause wire to break, leading to catastrophic failures. (4) design consideration pcb warpage after mounting the products onto a pcb can cause the package to break. the led should be placed in a way to minimize the stress on the leds due to pcb bow and twist. the position and orientation of the leds affect how much mechanical stress is exerted on the leds placed near the score lin es. the led should be placed in a way to minimize the stress on the leds due to board flexing. board separation must be perf ormed using special jigs, not using hands. volatile organic compounds that have been released from materials present around the leds (e.g. ho using, packing, adhesive, secondary lens, lens cover, etc.) may penetrate the led lens and/or encapsulating resin . if the leds are being used in a hermetically sealed environment, these volatile compounds can discolor after be ing exposed to heat and/or photon energy and it may greatly reduce the led light output and/or cause a color shift. in this case, ventilating the environment may improve the reduction in light output and/or color shi ft. perform a light-up test of the chosen application for optical evaluation to ensure that there are no issues, especially if the leds are planned to be used in a hermetically sealed environment. (5) electrostatic discharge (esd) the products are sensitive to static electricity or surge voltage. esd can damage a die and its re liability. when handling the products, the following measures against electrostatic discharge are strongly recommended: eliminating the charge grounded wrist strap, esd footwear, clothes, and floors grounded workstation equipment and tools esd table/shelf mat made of conductive materials ensure that tools (e.g. soldering irons), jigs and machines that are being used are properly grounded and that proper grounding techniques are used in work areas. for devices/equipment that mount the leds, protection against surge voltages should also be used. i f tools or equipment contain insulating materials such as glass or plastic, the following measures against electrostatic discharge are strongly recommended: dissipating static charge with conductive materials preventing charge generation with moisture neutralizing the charge with ionizers the customer is advised to check if the leds are damaged by esd when performing the characteristics inspection of the leds in the application. damage can be detected with a forward voltage measurement or a light- up test at low current (1ma). esd damaged leds may have current flow at a low voltage or no longer illuminate at a low current. failure criteria: v f <2.0v at i f =0.5ma
nichia sts-da1-3082c 16 (6) thermal management proper thermal management is a n important when designing products with leds. led die temperature is affected by pcb thermal resistance and led spacing on the board. please design products in a way that the led die temperature does not exceed the maximum junction temperature (t j ). drive current should be determined for the surrounding ambient temperature (t a ) to dissipate the heat from the product. the following equations can be used to calculate the junction temperature of the products. 1) t j =t a +r ja ? w 2) t j =t s +r js ? w *t j =led junction temperature: c t a =ambient temperature: c t s =soldering temperature (cathode side): c r ja =thermal resistance from junction to ambient: c/w r js =thermal resistance from junction to t s measuring point: c/w w=input power(i f v f ): w ts point (7) cleaning the leds should not be cleaned with water, benzine, and/or thinner. if required, isopropyl alcohol (ipa) should be used. other solvents may cause premature failure to the leds due to the damage to the resin portion. the effects of such solvents should be verified prior to use. in addition, the use of cfcs such as freon is heavily regulated. when dust and/or dirt adheres to the leds, soak a cloth with isopropyl alcohol (ipa), then squeeze it before wiping the leds. ultrasonic cleaning is not recommended since it may have adverse effects on the leds depending on the ultrasonic power and how led is assembled. if ultrasonic cleaning must be used, the customer is advised to make sure the leds will not be damaged prior to cleaning. (8) eye safety in 2006, the international electrical commission (iec) published iec 62471:2006 photobiological sa fety of lamps and lamp systems, which added leds in its scope. on the other hand, the iec 60825-1:2007 laser safety standard removed leds from its scope. however, please be advised that some countries and regions have adopted standards based on the iec laser safety standard iec 60825-1:20112001, which still includes leds in its scope. most of nichia's leds can be classified as belonging into either the exempt group or risk group 1. high-power leds, that emit light containing blue wavelengths, may be classified as risk group 2. please proceed with caution when viewing directly any leds driven at high current, or viewing leds with optical instruments which may greatly increase the damages to your eyes. viewing a flashing light may cause eye discomfort. when incorporating the led into your product, please be careful to avoid adverse effects on the human body caused by light stimulation.
nichia sts-da1-3082c 17 (9) others this product is intended to be used for general lighting, household appliances, electronic devices (e.g. mobile communicati on devices); it is not designed or manufactured for use in applications that require safety critical functions (e. g. aircraft, automobiles, combustion equipment, life support systems, nuclear reactor control system, safety devices, spacecraft, submarine repeaters, traffic control equipment, trains, vessels, etc.). if the leds are planned to be used for these applications, unless otherwise detailed in the specification, nichia will neither guarantee that the product is fit for that purpose nor be responsible for any resulting property damage, injuries and/or loss of life/health. this product does not comply with iso/ts 16949 and is not intended for automotive applications. the customer shall not reverse engineer by disassembling or analysis of the leds without having pr ior written consent from nichia. when defective leds are found, the customer shall inform nichia directly before disassembling or ana lysis. the specifications and appearance of this product may change without notice; nichia does not guarantee the contents of this specification. both the customer and nichia will agree on the official specifications of supplied products before the volume production of a program begins.
