-It is easy to find static damaged LED dies by a light-on test with the minimum current value.

7-3. Caution of product assembly

-Regarding this product assembling on the heat sink, it is recommended to use M3 screw.

It might be good for screw tightening on the heat sink to do temporary tightening and final tightening.

In addition, please don’t press with excess stress on the product.

-The condition of the product assembling on the heat sink and the control of screw tightening torque needs to be optimized

according to the specification of the heat sink.

-Roughness, unevenness and burr of surface negatively impact thermal bonding between the product and heat sink and

increase heat thermal resistance between them.

Confidence of thermally and mechanical coupling between the product and heat sink are confirmed by checking

the mounting surface and measuring the case temperature of the product.

-In order to reduce the thermal resistance at assembly, it might be good to use TIM (Thermal Interface Material) on whole

contact surface of the product.

In case of using thermal grease for the TIM, it might be good to apply uniformly on the contact surface of the product.

In case of using thermal sheet for the TIM, it might be good to make sure that the product is NOT strained by stress when

the screws are tightened for assembly.

-For more information, please refer to application note "Instruction Manual(COB LED Package)".

Ref.CE-P3085 04/15

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", "Instruction Manual(COB LED

Package)".

* Citizen Electronics cannot guarantee if usage exceeds these recommended conditions.

Please use it after sufficient verification is carried out on your own risk if absolutely necessary.

-For more information, please refer to application note "Instruction Manual(COB LED Package)".

7-9. Eye Safety

-The International Electrical Commission (IEC) published in 2006 IEC 62471

”2006 Photobiological safety of lamps and lamp systems ” which includes LEDs within its scope.

When sorting single LEDs according to IEC 62471, almost all white LEDs can be classified

as belonging to either Exempt Group (no hazard) or Risk Group 1 (low risk).

-However, Optical characteristics of LEDs such as radiant flux, spectrum and light distribution are factors

that affect the risk group determination of the LED, and especially a high-power LED, that emits light

containing blue wavelengths,

might have properties equivalent to those of Risk Group 2 (moderate risk).

-Great care should be taken when directly viewing an LED that is driven at high current, has multiple

uses as a module or when focusing the light with optical instruments, as these actions might greatly

increase the hazard to your eyes.

-It is recommended to regard the evaluation of stand-alone LED packages as a reference

and to evaluate your final product.
