Preliminary
7-4. Thermal Design
-The thermal design to draw heat away from the LED junction is most critical parameter
for an LED illumination system. High operating temperatures at the LED junction adversely affect
the performance of LED’s light output and lifetime. Therefore the LED junction temperature should
not exceed the absolute maximum rating in LED illumination system.
-The LED junction temperature while operation of LED illumination system depends upon
thermal resistance of internal LED package (Rj-c), outer thermal resistances of LED package,
power loss and ambient temperature. Please take both of the thermal design specifications
and ambient temperature conditions into consideration for the setting of driving conditions.
-For more information, please refer to application note "Thermal Management".
7-5. Driving Current
-A constant current is required as an applying driving current to this product.
-Electrical transient might apply excess voltage, excess current and reverse voltage to the product(s).
They also affect negative impact on the product(s) therefore please make sure that no excess voltage,
excess current and reverse voltage is applied to the product(s) .
-Please verify that the selected driver and dimmer switch can drive CLC020 correctly.
7-6. Electrical Safety
-This product itself is designed to cover UL requirements that may apply on the final product. however,
the UL certification still needs to be granted as the final product level which is depending on the design structure,
materials used and how the LED is placed and fixed in the final product. Therefore please confirm electrical safety
and dielectric in final product.
-Component failures can be caused by excessive voltage.
-Discharge before handling this product.
-ESD sensitivity of this product is over 1000V (based on IEC61000-4-2).
