(4) Design Consideration
Volatile organic compounds that have been released from materials present around the LEDs (e.g. housing, packing,
adhesive, secondary lens, lens cover, etc.) may penetrate the LED lens and/or encapsulating resin.
If the LEDs are being used in a hermetically sealed environment, these volatile compounds can discolor after being exposed
to heat and/or photon energy and it may greatly reduce the LED light output and/or cause a color shift.
In this case, ventilating the environment may improve the reduction in light output and/or color shift.
Perform a light-up test of the chosen application for optical evaluation to ensure that there are no issues,
especially if the LEDs are planned to be used in a hermetically sealed environment.
Excessive forces on this product can cause the ceramic package to crack.
It is recommended to use a holder when fixing this product to a chassis.
It is recommended to use a thermal film or thermal grease between the product and a chassis for increased heat dissipation.
(5) Electrostatic Discharge (ESD)
The products are sensitive to static electricity or surge voltage. ESD can damage a die and its reliability.
When handling the products, the following measures against electrostatic discharge are strongly recommended:
Eliminating the charge
Grounded wrist strap, ESD footwear, clothes, and floors
Grounded workstation equipment and tools
ESD table/shelf mat made of conductive materials
Ensure that tools (e.g. soldering irons), jigs and machines that are being used are properly grounded and
that proper grounding techniques are used in work areas. For devices/equipment that mount the LEDs,
protection against surge voltages should also be used.
If tools or equipment contain insulating materials such as glass or plastic,
the following measures against electrostatic discharge are strongly recommended:
Dissipating static charge with conductive materials
Preventing charge generation with moisture
Neutralizing the charge with ionizers
(6) Thermal Management
Proper thermal management is an important when designing products with LEDs. LED die temperature is affected
by LED module thermal resistance and LED spacing. Please design products in a way that the LED die temperature
does not exceed the maximum Junction Temperature (TJ).
The dice temperature of the products should be calculated, using the case temperature (TC) of the product incorporated
into the end-product, by the following equation.
TJ=TC+RθJCW
*TJ=LED junction temperature: °C
TC=Case temperature: °C
RθJC=Thermal resistance from junction to TC measuring point: °C/W
W=Input power(IF×VF): W
