Luminaire and method of thermal radiation of the luminaire
摘要：
According to one embodiment, a luminaire includes: a light-emitting portion (20) having a light-emitting element; a circuit board (30) having a notch (31) or a through hole (32); an electronic component (40) mounted on a side of a second main surface (30b) opposite to a first main surface (30a) of the circuit board (30); a thermal radiator (10) provided on a side of the first main surface (30a) and including the light-emitting portion (20) disposed on the thermal radiator (10); a thermally-conductive medium (50) disposed on the side of the first main surface (30a) of the circuit board (30) and being in contact with the electronic component (40) through the notch (31) or the through hole (32), and capable of transferring heat generated by the electronic component (40) to the side of the first main surface (30a) of the circuit board (30); and an outer frame member (60) accommodating the light-emitting portion (20), the circuit board (30), the electronic component (40), and the thermally-conductive medium (50).
摘要（中）：

根据一个实施例，一种照明器包括：具有发光元件的发光部分（20）; 具有凹口（31）或通孔（32）的电路板（30）; 安装在与所述电路板（30）的第一主表面（30a）相对的第二主表面（30b）侧的电子部件（40）; 设置在所述第一主表面（30a）的一侧并且包括设置在所述散热器（10）上的所述发光部分（20）的散热器（10）; 设置在所述电路板（30）的所述第一主表面（30a）侧并且通过所述凹口（31）或所述通孔（32）与所述电子部件（40）接触的导热介质（50） ），能够将由电子部件（40）产生的热量传递到电路基板（30）的第一主面（30a）侧。 以及容纳发光部（20）的外框构件（60），电路基板（30），电子部件（40）和导热介质（50）。
