(2) directions for use the circuit must be designed to ensure that the absolute maximum ratings are not exceeded for each led. the leds should be operated at a constant current per led. in the case of operating at a constant voltage, circuit b is recommended. if circuit a is used, it may cause the currents flowing through the leds to vary due to the variation in the forward voltage characteristics of the leds on the circuit. this led is designed to be operated at a forward current. ensure that no voltage is applied to the led in the forward/rever se direction while the led is off. if the leds are used in an environment where reverse voltages are applied to the led continuously, it may cause electrochemical migration to occur causing the led to be damaged. when not in use for a long period of time, the systems power should be turned off to ensure that there are no issues/damage. when using the leds with a dimmer, the color may vary depending on the current through the led; it is recommended to operate the led with pulse width modulation (pwm) to minimize this issue. to stabilize the led characteristics while in use, nichia recommends that the leds are o perated at currents 10% of the sorting current. ensure that transient excessive voltages (e.g. lighting surge) are not applied to the leds. if the leds are used for outdoor applications, ensure that necessary measures are taken (e.g. protecting the leds from water/salt damage and high humidity). (3) handling precautions do not handle the leds with bare hands: - this may contaminate the led surface and have an effect on the optical characteristics, - this may cause the led to deform a nd/or the wire to break causing a catastrophic failure (i.e. the led not to illuminate). ensure that when handling the leds with tweezers, excessive force is not applied to the led. otherwise, it may cause damage to the resin (e.g. cut, scratch, chip, crack, delamination and deformation) and the wire to break causing a catastrophic failure (i.e. the led not to illuminate). dropping may cause damage to the led (e.g. deformation). do not stack the leds. otherwise, it may cause damage to the resin (e .g. cut, scratch, chip, crack, delamination and deformation) and the wire to break causing a catastrophic failure (i.e. the led not to illuminate).

nichia sts - da1 - 4973a 19 (4) design consideration volatile organic compounds that have been released from materials present aroun d the leds (e.g. housing, gasket/seal, 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 being exp osed to heat and/or photon energy and it may greatly reduce the led light output and/or color shift. in this case, ventilating the environment may improve the redu ction in light output and/or color shift. perform a light - up test of the chosen application f or optical evaluation to ensure that there are no issues, especially if the leds are planned to be used in a hermetically sealed environment. this led uses a ceramic material for the substrate; if the led is attached to a housing in an inappropriate man ner (e.g. uneven application of force to the ceramic substrate, unstable holding, etc.), it may cause the substrate to crack. nichia recommend s using a specially designed holder to attach the leds to a housing. if the leds are attached to a housing with out a thermal interface material (e.g. thermal film, thermal grease, etc.), it may cause the heat dissipation to decrease. nichia recommends using a thermal interface material between the led and housing. (5) electrostatic discharge (esd) this led is s ensitive to transient excessive voltages (e.g. esd, lightning surge). if this excessive voltage occurs in the circuit, it may cause the led to be damaged causing issues (e.g. the led to become dimmer or not to illuminate [i.e. catastrophic failure ]). en sure that when handling the leds, necessary measures are taken to protect them from an esd discharge. the following examples are recommended measures to eliminate 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 all necessary measures are taken to prevent the leds from being exposed to transient excessive voltages (e.g. e sd, lightning surge): - tools (e.g. soldering irons), jigs, and machines that are used are properly grounded - appropr iate esd materials/equipment are used in the work area - the system/assembly is designed to provide esd protection for the leds. if the tool/equipment used is an insulator (e.g. glass cover, plastic, etc.), ensure that necessary measures have bee n taken to protect the led from transient excessive voltages (e.g. esd). the following examples are recommended measures to eliminate the charge: - dissipating static charge with conductive materials - preventing charge generation with moisture - neutralizing the charge with ionizers
nichia sts - da1 - 4973a 20 (6) thermal management when using this product, ensure that proper thermal management is provided and the die temperature does not exceed the maximum junction temperature (t j ). the temperature at the led junction, once the saturation temperature has been reached, can be calcul ated using 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 measurement point: c/w w=input power(i f v f ): w r jc may change depen ding on the properties for both the thermal interface material used (e.g. film, gel sheet, paste, or glue) and the heat sink/housing and the surface state of those materials. ensure that when mounting the leds on to the heat sink/housin g, the following poi nts are considered: - a thermal interface material with a low thermal resistance should be used for the interface between the led and heat sink/housing. - the surface of the heat sink used with the leds must not have any small recesses, cavities, or holes; if necessary, the surface must be leveled before mounting the leds. - if a holder and/or thermal interface material are used, ensure that these materials are properly used and the heat is effectively dissipated. during use if the thermal interface material deteriorates due to heat and the dimensions change and/or the properties degrade , it may cause these materials not to dissipate the heat properly; this may cause the led to be damaged. ensure that reliabilit y verification is performed for the chosen application. when measuring the temperatures of leds for the thermal management design, a non - contact temperature measuring instrument (e.g. thermal imaging camera) should be used. refer to the relevant applic ation notes for detailed information (e.g. how to handle the cob leds, the effect of adhesion strength between the cob and the housing, thermal design considerations, etc.). to access the application notes, go to the technical suggestions and recommendatio ns section of nichias website. (7) cleaning do not clean the leds with water, benzine and/or thinner. to clean the leds, use isopropyl alcohol (ipa). if another solvent is used, it may cause the led package/resin to be damage d causing issues; ensur e that sufficient verification is performed prior to use. additionally, ensure that the solvent being used does not cause any other issues (e.g. cfc - based solvents are heavily regulated). if an led is contaminated (e.g. dust/dirt), use a cloth soaked wi th isopropyl alcohol (ipa). ensure that the cloth is firmly squeezed before wiping the led. do not clean the leds with an ultrasonic cleaner. if cleaning must be done, ensure that sufficient verification is performe d by using a finished assembly with le ds to determine cleaning conditions (e.g. ultrasonic power, led position on the pcb assembly) that do not cause an issue. t c m e a s u r e m e n t p o i n t
nichia sts - da1 - 4973a 21 (8) eye safety there may be two important international specifications that should be noted for safe use of the leds: iec 62471:2 006 photobiological safety of lamps and lamp systems and iec 60825 - 1:2001 (i.e. edition 1.2) safety of laser products - part 1: equipment classification and requirements. ensure that when using the leds, there are no issues with the following points: - leds have been removed from the scope of iec 60825 - 1 since iec 60825 - 1:2007 (i.e. edition 2.0) was published. however, depending on the country/region, there are cases where the requirements of the iec 60825 - 1:2001 specifications or equi valent must be adhered to. - leds have been included in the scope of iec 62471:2006 since the release of the specification in 2006. - most nichia leds will be classified as the exempt group or risk group 1 according to iec 62471:2006. however, in the case of high - power leds containing blue wavelengths in the emission spectrum, there are leds that will be classified as risk group 2 depending on the characteristics (e.g. radiation flux, emission spectrum, directivity, etc.) - if the led is used in a manner that produces an increased output or with an optic to collimate the light from the led, it may cause damage to the human eye. if an led is operated in a manner that emits a flashing light, it may cause health issu es (e.g. visual stimuli causing eye discomfort). the system should be designed to ensure that there are no harmful effects on the human body.
