Appendix1-Rev1.0 LED lamps LED lamps (8) Variation of luminous intensity depending on ambient temperature ROHM LED lights have a temperature coefficient of approximately -1% for red and orange, and 0.5% for yellow and green. (Refer to the luminous intensity vs. case temperature characteristics for each LED type.) Storage precautions Storage in a dry box is best. However, if this is not possible we recommend the following conditions : Temperature : 5 to 30C Humidity : 60%RH max. Recommended PCB We recommend the following hole diameters. Note, however, that these may vary depending on the board material, degree of integration, and wiring. Determine the pulse drive conditions as follows. 1. Decide what repetition frequency (f) and duty factor (DF) will be used. 2. Determine the maximum tolerable peak current ratio from Figure 2. IF peak Max. IF Max. 3. Determine the maximum forward current from Figure 3. For example, when Ta = 40C or above, the maximum forward current (IF Max.) decreases. 4. Calculate the maximum tolerable peak current (IF peak Max.). Example If f = 1 kHz, DF = 10%, and Ta = 40C, the maximum tolerable peak current ratio from Figure 2 is 3.0 for red, orange and yellow, and 2.4 for green. The maximum forward current IF Max. at Ta = 40C is 20 mA for red, orange and yellow, and 25 mA for green. Therefore, the maximum tolerable peak current under these conditions is as follows : Red, orange and yellow . . 20 mA 3.0 = 60 mA Green . . . . . . . . . . . . . . . . . . 25 mA 2.4 = 60 mA For the repetition frequency, we recommend 1 kHz or above. (7) Decrease of rated current The maximum rated forward current of LED lamps will vary depending on the ambient operating temperature.
