nichia sts-da1- 531 5 37 (2) directions for use the circuit must be designed to ensure that the absolute maximum ratings are not e xceeded for each le d. the leds should be operated at a constant current per led. in the case of operating at a constant voltage, circuit b is recomm ended. if circuit a is used, it may cause the currents flowing through the leds to vary due to the varia tion in the forward voltage characteristics of the leds on the circuit. (a) ... (b) ... 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 v oltages 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/dama ge. to stabilize the led characteristics while in use, nichia recommends that the leds are operated at currents 10% of the so rting current. ensure that transient excessive voltages (e.g. lighting surge) are not applied to the leds. if the leds are u sed 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 and/or the wire to break causing a catastrophic failure (i.e. the led not to il luminate). 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 t o 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 assembled pcbs together. otherwise, it may cause damage to the resi n (e.g. cut, scratch, chip, crack, delamina tion and deformation) and the wire to break causing a catastrophic failure (i.e. the led not to illuminate). cri rank r9050 leds in this specification use materials that contain halogen-based compounds; the ha logen element found in these materials will not affect the leds when the leds are used under the conditions det ailed in this specification. the other cri ranks in this specification do not use these materials. due to the variation in the amount of the reflective material (white resin) that is coating the protection device, the area around the protection device may appear to be a black spot; this will not affect the characteristics of the led. do not use the location of the protection device to determine the polarity of the led; use the cathode mark. (4) design consideration if the leds are soldered to a pcb and the pcb assembly is bent (e.g. pcb depane ling process), it may cause the led package to break. the pcb layout should be designed to minimize the mechanical stress on the leds when the pcb assembly is bent/warped. the amount of mechanical stress exerted on the led from depaneling may vary depen ding on the led position/orientation on the pcb assembly (e.g. especially in areas near v-groove scores). the pcb layout should be designed to minimize the mechan ical stress on the leds when the pcb is separated into individual pcb assemblies. to separa te a pcb populated with the leds, use a specially designed tool. do not break the pcb by hand. volatile organic compounds that have been released from materials present around the led s (e.g. housing, gasket/seal, adhes ive, 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 exposed to heat and/or photon energy an d it may greatly reduce the led light output and/or color shift. in this case, ventila ting the environment may improve the reduction in light output and/or color shift. perform a light-up test of the chosen application fo r optical evaluation to ensure that there are no issues, especially if the leds are planned to be used in a hermetically sealed environment.
nichia sts-da1- 531 5 38 (5) electrostatic discharge (esd) this led is sensitive 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]). ensure 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 p revent the leds from being exposed to transient excessive voltages (e.g. esd, lightning surge): - tools (e.g. soldering irons), jigs, and machines that are used are properly grounded - appropriate 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 necessar y measures have been take n 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 to detect if an led was damaged by transient excess voltages (i.e. an esd event during t he systems assembly process), perform a characteristics inspection (e.g. forward voltage measurement) at low current (2ma). failure criteria: v f <2.0v at i f =1.0ma if the led is damaged by transient excess voltages (e.g. esd), it will cause the forward voltage (v f ) to decrease. (6) thermal management the absolute maximum junction temperature (t j ) must not be exceeded under any circumstances. the increase in the temperature of an led while in operation may vary depending on the pcb thermal resistance and the density of leds on the pcb assembly. ensure that when using the leds for the chosen application, heat is not concen trated in an area and properly manage d in the system/assembly. the operating current should be determined by considering the temperature conditions surroundi ng the led (i.e. t a ). ensure that when operating the led, proper measures are taken to dissipate the heat. the following equations can b e used to calculate the led temperature (i.e. t j ) once the saturation temperature at the junction has been reached. 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 measurement point: c/w w=input power(i f v f ): w t s measurement point
nichia sts-da1- 531 5 39 (7) cleaning do not wipe/clean the leds with a damp clo th soaked in water or solvents (e.g. benzine, thinner, etc.). if required, use isopropyl alcohol (ipa). if water or other solvent is used, it may cause is sues. before using the solvent, ensure that sufficient verification is performed to ensure that the solvent does not adversely affect the leds. i n addition, the use of cfcs such as freon is heavily regulated. when a foreign substance (e.g. dust, debris, loose materials, etc.) adheres to the leds, wipe it o ff with a damp well -squeezed cloth that was soaked only in isopropyl alcohol (ipa). do not wipe the emitting surface. otherwise, it may result in excessive pressure to the emitting surface causing issues (e. g. wire to deform, the encapsulating resin to become damaged, the color to change, etc.). if wiping the emitting surface is nece ssary, ensure that sufficient preliminary verification is performed to ensure that there are no issues; wipe the emitting surface at the customers risk. do not clean the leds with an ultrasonic cleaner. if cleaning must be done, ensure that sufficient verification is performed by using a finished assembly with leds to determine cleaning conditions (e.g. ultrasonic power, led position on the pcb assembly) that do not cause an issue. (8) eye safety there may be tw o important international specifications that should be noted for safe use of the leds: iec 62471:2006 photobiological safety of lamps and lamp systems and iec 60825-1:2001 (i.e. edition 1.2) safety of laser products - p art 1: equipment classification and requirements. ensure that when using the leds, there are no issues with the fol lowing 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 60825-1:200 1 specifications or equivalent must be adhered to. - leds have been included in the scope of iec 62471:2006 since the release of the specification in 2 006. - 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 cla ssified as risk group 2 depending on the characteristics (e.g. radiation flux, emission spectrum, directivit y, etc.) - if the led is used in a manner that produces an increased output or with an opti c 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 hea lth issues (e.g. visual stimuli causing eye discomfort). the system should be designed to ensure that there are no harmful effects on the human body.
