eye-response curve.  
θ
2. 1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.  
λ
3. The dominant wavelength,  
d is derived from the CIE chromaticity diagram and represents the single  
wavelength which defines the color of the device.

CAUTIONS  
1. Application  
The LEDs described here are intended to be used for ordinary electronic equipment (such as office  
equipment, communication equipment and household applications).Consult Liteon’s Sales in advance  
for information on applications in which exceptional reliability is required, particularly when the failure  
or malfunction of the LEDs may directly jeopardize life or health (such as in aviation, transportation,  
traffic control equipment, medical and life support systems and safety devices).  
2. Storage  
The storage ambient for the LEDs should not exceed 30°C temperature or 70% relative humidity.  
It is recommended that LEDs out of their original packaging are IR-reflowed within one week.  
For extended storage out of their original packaging, it is recommended that the LEDs be stored in a  
sealed container with appropriate desiccant, or in a desiccators with nitrogen ambient.  
LEDs stored out of their original packaging for more than a week should be baked at about 60 deg C  
for at least 24 hours before solder assembly.  
3. Cleaning  
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED if necessary.  
4. Soldering

5. Drive Method  
An LED is a current-operated device. In order to ensure intensity uniformity on multiple LEDs  
connected in parallel in an application, it is recommended that a current limiting resistor be incorporated  
in the drive circuit, in series with each LED as shown in Circuit A below.  
Circuit model A  
Circuit model B  
LED  
LED  
(A) Recommended circuit.  
(B) The brightness of each LED might appear different due to the differences in the I-V characteristics  
of those LEDs.  
6. ESD (Electrostatic Discharge)  
Static Electricity or power surge will damage the LED.  
Suggestions to prevent ESD damage:  
„ Use of a conductive wrist band or anti-electrostatic glove when handling these LEDs.  
„ All devices, equipment, and machinery must be properly grounded.  
„ Work tables, storage racks, etc. should be properly grounded.  
„ Use ion blower to neutralize the static charge which might have built up on surface of the LED’s  
plastic lens as a result of friction between LEDs during storage and handling.

LITE-ON TECHNOLOGY CORPORATION  
P r o p e r t y o f L i t e - O n O n l y  
ESD-damaged LEDs will exhibit abnormal characteristics such as high reverse leakage current, low  
forward voltage, or “ no lightup ” at low currents.  
To verify for ESD damage, check for “ lightup ” and Vf of the suspect LEDs at low currents.  
The Vf of “ good ” LEDs should be >2.0V@0.1mA for InGaN product and >1.4V@0.1mA for AlInGaP  
product.
