(8) Variation of luminous intensity depending on ambi-
ent 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.)
FStorage precautions
Storage in a dry box is best. However, if this is not pos-
sible we recommend the following conditions :
Temperature : 5 to 30_C
Humidity : 60%RH max.
FRecommended PCB
We recommend the following hole diameters. Note, how-
ever, thatthesemayvarydependingontheboardmateri-
al, 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 = 40_C or above, the maximum
forward current (IF Max.) decreases.
4. Calculate the maximum tolerable peak current (IF
peak Max.).
FLED lamp product names
The product names of ROHM LED lamps and chip LEDs
are coded as follows :
Example
Iff=1kHz, DF=10%, andTa=40_C, themaximumtoler-
ablepeakcurrentratiofromFigure2is3.0forred, orange
and yellow, and 2.4 for green.
The maximum forward current IF Max. at Ta = 40_C 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 :
FRed, orange and yellow . . 20 mA 3.0 = 60 mA
FGreen . . . . . . . . . . . . . . . . . . 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.
(Refer to Figure 3)
