-3- (2) installation the following figure shows the lum i nous intensity standard led should be held by a holder. the m easurem ent distance shall start from the top surface of the led. please refer to ?outline dimensions? on the following page. the surface of detector shall be perpendicula r to the m echanical axis of the standard led. (3) measurem ent the standard led should be m easured when the lum i nous intensity has stabilized after the start of tem perature control and constant current drive. typically, the standard led will be stable and ready to be used f o r calibration within 1 to 3 m i nutes. please refer to ?typ.characteristics? on the following page for the characteristics during the first 5 m i nutes after the led starts em ission. 11.cautions (1) storage this product should be kept at 30c or less a nd 70% rh or less. w h en storing, m o isture proof packaging with absorbent m aterial (silica gel) is recom m ended. please avoid rapid transitions in am bient tem perature, especially in high hum idity environm ents where condensation can occur. (2) static electricity static electricity or surge voltage dam ages the leds. it is recom m ended that a wrist band or an anti-electrostatic glove be used when handling the leds. all devices, equipm ent and m achinery m u st be properly grounded. it is recom m ended that precautions be taken against surge voltage to the equipm ent that m ounts the leds. w h en inspecting the final products in which leds were assem b led, it is recom m ended to check whether the assem b led leds are dam aged by static electricity or not. it is easy to find static-dam aged leds by a light-on test or a vf test at a lower current (below 1m a is recom m ended). dam aged leds will show som e unusual characteristics such as the forward voltage becom es lower, or the leds do not light at the low current. c r i t e r i a : ( v f > 2.0v at i f =0.5m a) exam ple 1: (h eld by the part w ith 25m m diam eter) exam ple 2: (h eld by the part w ith 20m m diam eter) a holde r a holde r nichia sts-da1-0563
-4- (3) saf ety guideline f o r hum an eyes the international electrical com m i ssion (iec) published in 2006 iec 62471: 2006 photobiological safety of lamps and lamp systems which includes leds within its scope. meanwhile leds were rem oved from the scope of the iec 60825-1:2007 laser safety standard, the 2001 edition of which included led sources within its scope. however, keep in m i nd that som e countries and regions have adopted standards based on the iec laser safety standard iec 60825-1:2001 which includes leds within its scope. following iec 62471:2006, m ost of nichia leds can be classified as belonging to either exem pt group or risk group 1. optical characteristics of a led such as output power, spectrum and light distribution are factors that affect the risk gr oup determ ination of the led. especially a high-power led, that em its light containing bl ue wavelengths, m a y be in risk group 2. great care should be taken when viewing directly the led driven at high current or the led with optical instrum ents, which m ay greatly increase the hazard to your eyes. (4) others flashing lights have been known to cause discom fort in people; you can prevent this by taking precautions during use. also, people should be cautious when using equipm ent that has had leds incorporated into it. this product is designed to be used for calibration. do not use this product for any other purposes or other applications. user shall not reverse engineer by disassem bling or analysis of the leds without having prior written consent from nichia. w h en defective leds are found, the user shall inform nichia directly before disassem b ling or analysis. the form al specifications m u st be excha nged and signed by both parties before purchase. the appearance and specifications of the product m ay be m odified for im provem ent without notice. nichia sts-da1-0563
