Temperature controller Standard LED Constant current power supply for LED drive Digital multimeter (Vf measurements) Recommended specifications for the peripheral equipments Temperature controller PID controller. Temperature measurement accuracy of ± 0.03°C. Constant current power supply Drive current accuracy: ≤ 0.1% of the set current for LED drive Digital multimeter (Vf measurements) Input impedance: ≥ 1 GΩ Please refer to “INTERNAL CIRCUIT”on the following page for circuit wiring. -2- Nichia STS-DA1-0567 <Cat.No.081105> (2) Installation · The following figure shows the Luminous Flux Standard LED should be held by a holder. Example 1: Example 2: (Held by the part with 25mm diameter) (Held by the part with 20mm diameter) A holder A holder · The measurement distance shall start from the top surface of the LED. Please refer to “OUTLINE DIMENSIONS” on the following page. (3) Measurement · The Standard LED should be measured when the luminous flux has stabilized after the start of temperature control and constant current drive. Typically, the standard LED will be stable and ready to be used for calibration within 1 to 3 minutes. Please refer to “TYP.CHARACTERISTICS ” on the following page for the characteristics during the first 5 minutes after the LED starts emission. 11.CAUTIONS (1) Storage · This product should be kept at 30°C or less and 70%RH or less. When storing, moisture proof packaging with absorbent material (silica gel) is recommended. · Please avoid rapid transitions in ambient temperature, especially in high humidity environments where condensation can occur. (2) Static Electricity · Static electricity or surge voltage damages the LEDs. It is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs. · All devices, equipment and machinery must be properly grounded. It is recommended that precautions be taken against surge voltage to the equipment that mounts the LEDs. · When inspecting the final products in which LEDs were assembled, it is recommended to check whether the assembled LEDs are damaged by static electricity or not. It is easy to find static-damaged LEDs by a light-on test or a VF test at a lower current (below 1mA is recommended). · Damaged LEDs will show some unusual characteristics such as the forward voltage becomes lower, or the LEDs do not light at the low current. Criteria : (VF > 2.0V at IF=0.5mA) -3- Nichia STS-DA1-0567 <Cat.No.081105> (3) Safety Guideline for Human Eyes · The International Electrical Commission (IEC) published in 2006 IEC 62471:2006 Photobiological safety of lamps and lamp systems which includes LEDs within its scope. Meanwhile LEDs were removed 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 mind that some 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, most of Nichia LEDs can be classified as belonging to either Exempt Group or Risk Group 1. Optical characteristics of a LED such as output power, spectrum and light distribution are factors that affect the risk group determination of the LED. Especially a high-power LED, that emits light containing blue wavelengths, may be in Risk Group 2. Great care should be taken when viewing directly the LED driven at high current or the LED with optical instruments, which may greatly increase the hazard to your eyes. (4) Others · Flashing lights have been known to cause discomfort in people; you can prevent this by taking precautions during use. Also, people should be cautious when using equipment 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 disassembling or analysis of the LEDs without having prior written consent from Nichia. When defective LEDs are found, the User shall inform Nichia directly before disassembling or analysis. · The formal specifications must be exchanged and signed by both parties before purchase. · The appearance and specifications of the product may be modified for improvement without notice. -4- Nichia STS-DA1-0567 <Cat.No.081105> Time vs. Relative Chromaticity Coordinate x 0.003 0.002 0.001 0 -0.001 -0.002 0 100 200 300 0.003 0.002 0.001 0 -0.001 -0.002 -0.003 0 100 Time (s) Relative Luminous Flux (%) Relative Chromaticity Coordinate y 100 200 Time (s) (注1) (注2) (注3) 300 1.2 1 0.8 0.6 0.4 0.2 0 300 400 500 600 700 800 Wavelength λ (nm) Time vs. Relative Chromaticity Coordinate y 0.5 0.4 0.3 0.2 0.1 0 -0.1 -0.2 -0.3 -0.4 -0.5 0 200 Time (s) Time vs. Relative Luminous Flux Spectrum Relative Emission Intensity (a.u.) 0.004 Relative Chromaticity Coordinate x Relative Forward Voltage Vf (V) Time vs. Relative Forward Voltage 300 Ta=30℃ Ta=25℃ Ta=20℃ 0.003 0.002 0.001 0 -0.001 -0.002 -0.003 0 100 200 300 Time (s) 標準ＬＥＤに取り付けられた白金測温抵抗素子の温度が30℃になるように温度コントロールしたときの特性です(If=20mA)。 温度コントローラーの温度制御安定度は±0.03℃です(メーカー仕様値)。 点灯時間－相対順電圧特性、点灯時間－相対光束特性、点灯時間－相対色度x特性、 点灯時間－相対色度y特性は、Ta=25℃、ＬＥＤ点灯300s後の値を基準としています。 (NOTE 1) The graphs show the characteristics when the platinum RTD incorporated in the Standard LED is controlled to be 30±0.03℃(If=20mA).
