More than half of the heat generated at the LED light source is directly transmitted via the path LED -> filling gas -> vessel or indirectly via the path LED -> carrier -> filling gas -> vessel via the filling gas 5 to the Transfer vessel wall.
- the filling gas comprises a mixture of at least one gas having a high thermal conductivity and at least one gas having a different physical property.
- helium or hydrogen can be used as the high thermal conductivity gas.
