Heat Release Design For Fixtures; Tlt Standard Heat Sink - Toshiba LEV112320W827TE Technical Information

(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.
