(7) 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 this specification.
· Please determine the operating current with consideration of the ambient temperature local to the LED
and refer to the plot of Ambient temperature vs. Allowable Forward Current on CHARACTERISTICS
in this specifications. Please also take measures to remove heat from the area near the LED to improve
the operational characteristics of the LED.
· The equation 1 indicates correlation between Tj and Ta, and the equation 2 indicates correlation
between Tj and Ts.
Tj=Ta + Rja W
1
Tj=Ts + Rjs W
2
Tj = Dice Temperature : °C, Ta = Ambient Temperature : °C,
Ts = Solder Temperature (Cathode Side) : °C,
Rja = Heat resistance from Dice to Ambient temperature : °C /W,
Rjs = Heat resistance from Dice to Ts measuring point ≒ 65°C /W,
W = Inputting Power (IF
VF) : W
(8) Others
· The LED light output is strong enough to injure human eyes. Precautions must be taken to prevent
looking directly at the LEDs with unaided eyes for more than a few seconds.
· Flashing lights have been known to cause discomfort in people; you can prevent this by taking
precautions during use. Also, people should be cautious when using equipment that has had LEDs
incorporated into it.
· The LEDs described in this brochure are intended to be used for ordinary electronic equipment (such
as office equipment, communications equipment, measurement instruments and household appliances).
Consult Nichia’s sales staff in advance for information on the applications in which exceptional quality
and reliability are required, particularly when the failure or malfunction of the LEDs may directly
jeopardize life or health (such as for airplanes, aerospace, submersible repeaters, nuclear reactor
control systems, automobiles, traffic control equipment, life support systems and safety devices).
· User shall not reverse engineer by disassembling or analysis of the LEDs without having prior written
consent from Nichia.
When defective LEDs are found, the User shall inform Nichia directly before
disassembling or analysis.
· The formal specifications must be exchanged and signed by both parties before large volume purchase begins.
· The appearance and specifications of the product may be modified for improvement without notice.
