7 Precautions
7-1．General handling
① The voltage must be applied to LED only as a forward direction. Moreover, please design
circuit diagram considering no voltage gap between Anode and Cathode during off state.
If the reverse voltage is applied to LED for a long term, the electro-migration is generated
and there is a possibility of the short-circuit of the circuit.

② This product is sensitive for electrostatic voltageand surge voltage.Static electricity or surge
voltage can deteriorate product and its reliability. Please make sure that all devices and
equipments must be grounded.
We recommend to built in zener diode or TVS(Transient Voltage Suppression) as
protectioncircuit against static electricity.
③ This product is composed of blue LED chip and special phosphor.
Color tone is possibleto vary in some degree, depending on the operating conditions such
as ambient temperature or current amount. Also it is subject to variation due to the
afterglow of the phosphor in pulse drive.
So please verify the performancebefore use.
④ Do not look directly at LEDs with unshielded eyes, or damage to your eyes may result.
⑤ Materials with high thermal conductivity are used in this product in order to allow generated
heat to escape effectively out of the product.Avoid locating other heat sources
(ex. resistance, etc.) near the products on circuit board to protect the devices from the
heatdamage. Please make sure that case temperature is always under 100 ℃
during operation, including the self-heating.
⑥ Since dust on the surface of the radiation part is hard to remove and may decrease the
luminous intensity, please handle the products in a clean, non-dusty condition.
⑦ The lensof this product is formed with silicone resin. In the case of handling this device,
please do not push the lens portion by the sharp tools. The crackandpeeloffof the lens,
and the wire deformation are generated and it causes not lighting.
・ Especially do not apply the load from horizontal direction to the side of the lens of this product.
・ Please do not apply the static loadof 2.5N or more (1.4mmφor less)fromthe diagonal 45
degrees of this productslens portion to the direction of an optical axis.
⑧ This product is the small size andthe lens portion is formed by silicone resin, there isa
possibilityto have damage by the external stress.
