5. Heat Generation

• Thermal design of the end product is of paramount importance. Please consider the heat

generation of the LED when making the system design. The coefficient of temperature

increase per input electric power is affected by the thermal resistance of the circuit board and

density of LED placement on the board, as well as other components. It is necessary to

avoid intense heat generation and operate within the maximum ratings given in the

specification.

• The operating current should be desided after sonsidering the ambient maximum

temperature of LEDs.

6. Storage

• The LEDs should be stored at 30°C or less and 70%RH or less after being shippedand the

sorage life limits are 3 months. If the LEDs are stored for 3 months or more, they can be

stored for a year in a sealed container with nitrogen atmosphere and moisture absorbent

material.

• Please avoid rapid transistions in ambient temperature, especially in high humidity

environments where condensation can occur.
