Thermal Management
The optical, electrical, and reliability characteristics of the
LED are affected by temperature. Keep the junction
temperature (TJ) of the LED below the allowable limit at all
times. TJ can be calculated as follows:
TJ = TA + RθJ-A x IF x VFmax
where:
TA = Ambient temperature (°C)
RθJ-A = Thermal resistance from LED junction to
ambient (°C/W)
IF = Forward current (A)
VFmax = Maximum forward voltage (V)
The complication of using this formula lies in TA and RθJ-A.
Actual TA is sometimes subjective and hard to determine.
RθJ-A varies from system to system depending on design
and is usually not known.
Another way of calculating TJ is by using the solder point
temperature, TS as follows:
TJ = TS + RθJ-S x IF x VFmax
where:
TS = LED solder point temperature as shown in the
following figure (°C)
RθJ-S = Thermal resistance from junction to solder point
(°C/W)
IF = Forward current (A)
VFmax = Maximum forward voltage (V)
Figure 16: Solder Point Temperatures on PCB
TS can be easily measured by mounting a thermocouple on
the soldering joint as shown in preceding figure, while RθJ-S
is provided in the data sheet. Verify the TS of the LED in the
final product to ensure that the LEDs are operating within all
maximum ratings stated in the data sheet.
Eye Safety Precautions
LEDs may pose optical hazards when in operation. Do not
look directly at operating LEDs because it might be harmful
to the eyes. For safety reasons, use appropriate shielding or
personal protective equipment.
