Note: 

The specifications above are the values where the product is turned on the following conditions: the 

input voltage:230V, base-up positioned, the ambient temperature:25 ℃, using the TLT standard 

heat sink(Tc:50℃:1100lm type,Tc60℃:1600lm type), and at the first use (0hr lighting time).

3. Installation Manual 

We show a procedure to install LED Light Engine in Socket. 

(i)Make a direction △ mark of LLE even with Mechanical Key (which there is between earthing 

contact and no.4 contact)of the socket. 

(ii)Fit LLE in the socket. 

(iii)Turn it 15° in clockwise direction.

Socket moves about 0.5mm to the bottom of the figure. LLE is strongly attached to the heat sink by 

the spring built-in the socket.

△ mark 

To make the installation easier, we suggest to put a mark (like the △ mark above) on the fixture 

side.

4. Heat release design 

(1)Case Temperature (Tcase) measurement method 

We define Case Temperature (Tcase) that is the temperature of φ30mm of the cap center of LLE. 

Some characteristics of LLE depend on Tcase. 

And, tc defined by EN 62031 (rated maximum temperature) is evaluated the temperature at the 

measurement area. In the LLE, 

1100 lm type tc=65℃, 

1600 lm type tc=75℃, 

Tcase shall be measured with a thermocouple. By making a hole etc., avoid the attachment part with 

a thermocouple being apart from heat sink.

(2)Heat release design for fixtures 

To use the LED light engine safely and to exploit the product specification such as luminous output 

and life time, heat release design for fixtures is very important. That is why heat sink shall be 

attached to the socket side of the LED light engine. 

The heat sink design in this case can be reduced as long as the Tc remains under 65 ℃(1100 lm type), 

75℃(1600 lm type). 

This LED light engine has been designed to meet the rated luminous output and light maintenance 

at the Tcase=50℃(1100 lm type),Tcase=60℃(1600 lm type). In normal operating (for instance, 

ambient temperature 25℃, rated voltage input), we recommend to use a heat sink which Tcase 

become 50℃ or 60℃. 

(3)TLT standard heat sink 

Here, we show TLT standard heat sink. TLT standard heat sink has a hole(φ15) in the center for 

temperature measurement use.

(4)Heat releases silicon sheet 

The attached sheet on the base cap is heat release silicon sheet. This sheet has appropriate 

elasticity(thickness:0.5mm), which fill in the space between the light engine and heat sink, and 

greatly help heat release cycle from the light engine to heat sink. 

The heat release silicon sheet never shall be taken off.
