We transform the problem of energy dissipation into a problem of heat conduction by the introduction of external heat sink.

引入外部热汇后，我们将能量耗散问题转化为一个热传导问题。

If the machine temperature rise is too high, but also consider the problem of the installation of the fan, increase heat dissipation.

假如机器温升过高，还要思索问题加装风扇，增加散热。

Now there are still a number of technical difficulties in LED application for automotive headlamp, one more difficult to overcome of which is the heat dissipation problem of LED headlamp.

但目前LED运用于汽车前照灯还面临许多技术难点，其中较难克服的一部分是LED灯具的散热问题。
