1. Introduction
1-1. Product Description
CITIZEN ELECTRONICS is the first COB manufacture. Our advanced knowledge and packaging technology for many
years has excellent reliability and high quality of our products. CITILED COB Series covers a wide range of luminous flux
from a 10W incandescent bulb to a 500W sodium lamp in general lighting sources. The element arrangement of LED
package is capable of utilizing light more effectively and higher performance.
The new version of CITILED COB series increase the performance significantly from previous version. New version
creates more options to match luminaire's products design (ex. High performance , Cost effective , Small Light Emitting
Surface(LES), Increased allowable max. If). Emitted light density of the LED package is improved higher for suitable use of
light-condensing products. The outline and LES size is the same as for previous version. Thus existing parts of 3rd
parties are compatible in mechanical characteristics. All of specs are at hot binning (Tj=85℃).

-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 a connector.
In cases where M3 screw is used, it might be good for screw tightening on the heat sink to do temporary tightening and
final tightening with tightening torque of 0.4N・m.
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 grease as TIM (Thermal Interface Material)
on the 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.

Ref.CE-P3326 09/15
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.
-Please be aware that this product should be used not to exceed the Tc limit.
-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)".
7-5. Driving Current
-A constant current is recommended as an applying driving current to this product.
In the case of constant voltage driving, please connect current-limiting resistor to each products in series and control
the driving current to keep under the absolute maximum rating forward current value.
- This package shall be allowed for use only when each channel independently operates with one power source for one
channel. Neither series nor parallel connection that connects the two channels is allowed in the package.
- When different amount of current is applied to each channel, it is recommended that such difference is kept 10% or
smaller. However, some brightness variation can be produced between two channels even if the difference in current
between channels is 10% or smaller. For this reason, please conduct a sufficient verification using an apparatus.
-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, no excess current
and no reverse voltage is applied to the product(s) when the LED driver is turn-on and/or turn-off.
-If you desire to connect a driver in the series connection, it is required to contact a driver manufacturer beforehand to
check whether such a usage is acceptable. Also, please conduct a sufficient verification using an apparatus. Please be
aware that this product can be in excess of the working voltage range specified in the UL standard.
-For more information, please refer to application note "Driving", "Instruction Manual(COB LED Package)".
7-6. Lighting at a minimum current value
-In a case where the minimum current(IF min) is applied to the product, some of LED dice in the product might look
different in their brightness due to the individual difference of the LED dice, and they are not failed.
12
Ref.CE-P3326 09/15
7-7. Electrical Safety
-This product is designed and produced according to IEC 62031:2008
(IEC 62031:2008 LED modules for general lighting. Safety specification)
-Dielectric voltage withstand test has been conducted on this product to see any failure after applying
voltage between active pads and aluminum section of the product, and to pass at least 500V.
-Considering conformity assessment for IEC62031:2008, almost all items of the specification depend upon
your final product of LED illumination system.
Therefore, please confirm with your final product for electrical safety of your product.
As well, the products comply with the criteria of IEC62031:2008 as single LED package.
7-8. Recommended soldering Condition (This product is not adaptable to reflow process.)

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.
