(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 voltage, circuit b is recommended . if the leds are operated with constant voltage using circui t a, the current through the leds may vary due to the variation in forward voltage ch aracteristics of the leds. (a) ... (b) ... this product should be operated using forward curre nt. 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 long time, the main power supply should be switched off for safety. pulse width modulation (pwm) is recommended for dimm ing leds as color point changes with drive current. it is recommended to operate the leds at a current greater th an 10% of the sorting current to stabilize the led characteristic s. ensure that excessive voltages such as lightning surges are not applied to the leds. for outdoor use, necessary measures should be taken to prevent water, moisture and salt air damage. (3) handling precautions do not handle the leds with bare hands as it will contaminat e the led surface and may affect the optical characteristics: it might cause the led to be deformed and/or the wi re 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, ch ipped, delaminate or deform ed, causing wire-bond breaks and catastrophic failures. dropping the produc t may cause damage. do not stack assembled the products. fail ure to comply can cause the resin portion of the product to be cut, chipped, delaminated and/or deformed. it may cause wi re to break, leading to catastrophic failures.
nichia sts-da1-3444 15 (4) design consideration volatile organic compounds that have been released from materials present around the leds (e.g. housing, 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 enviro nment, these volatile compounds ca n discolor after being exposed to heat and/or photon energy and it may greatly re duce 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 shift. 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. excessive forces on this product can cause the ceramic package to crack. it is recommended to use a holder when fixing this product to a chassis. it is recommended to use a thermal film or thermal grease be tween the product and a chassis for increased heat dissipation. (5) electrostatic discharge (esd) the products are sensitive to static electricity or surge voltage. esd can damage a die and its reliability. 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 mach ines that are being used are properly grounded and that proper grounding techniques are used in wo rk areas. for devices/equipment that mount the leds, protection against surge voltages should also be used. if tools or equipment contain insulating materials such as glass or plastic, the following measures against electros tatic discharge are strongly recommended: dissipating static charge with conductive materials preventing charge generation with moisture neutralizing the charge with ionizers (6) thermal management proper thermal management is an impo rtant when designing produc ts with leds. led die temperature is affected by led module thermal resistance and led spacing. please design products in a way that the led die temperature does not exceed the maximum junction temperature (t j ). the dice temperature of the products should be calculated, using the case temperature (t c ) of the product incorporated into the end-product, by the following equation. t j =t c +r jc ? w *t j =led junction temperature: c t c =case temperature: c r jc =thermal resistance from junction to t c measuring point: c/w w=input power(i f v f ): w tc point
nichia sts-da1-3444 16 (7) cleaning the leds should not be cleaned with water, benzine, and/or thinner. if required, isopropyl alcohol (ipa) should be used. ot her 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 safety 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 ha ve 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 belo nging into either the exempt group or risk group 1. high-power leds, that emit ligh t 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. (9) others the leds described in this brochure are intended to be used for ordinary electronic equipment (such as office equipment, communications equipment, measurement instruments and household appliances). consult nichia's sales staff in advance for information on the applicat ions in which exceptional quality and reliability are required, particularly when the failure or malfunction of the leds may directly jeopardize life or health (such as for airplanes, aerospace, submersibl e repeaters, nuc lear reactor control system, automobiles, traffic control equipment, life support systems and safety devices). the customer shall not reverse engineer by disassembling or analysis of the leds without having prior written consent from nichia. when defective leds are found, the customer shall inform nichia directly before disassembling or analysis. the specifications and appearance of th is 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.
