    • An object of the present invention is to provide a light emitting element lamp and a lighting equipment effectively suppressing a temperature rising of a substrate on which a light emitting element is mounted by using a reflector. The present invention provides a light emitting element lamp 1 including: a heat-conductive reflector 2 having an emission opening portion and formed to be widened toward the emission opening portion with a reflecting surface 2a being provided on an inner surface side and an outer peripheral surface being exposed to an outside; a base 4 connected to the reflector 2 via a cover 3; a heat-conductive heat radiating member 8 provided on an inner peripheral surface of the reflector 2 and thermally connected to the reflector 2; a substrate 7 having a light emitting element 6 mounted thereon and attached to the heat radiating member 8 with a substrate surface being thermally connected to the heat radiating member 8 in a surface contact state; a lighting circuit 9 housed in the cover 3 to light the light emitting element 6; and a translucent cover 5 for covering the emission opening portion 2c of the reflector 2.
    • 本发明的目的是提供一种通过使用反射器有效地抑制其上安装有发光元件的基板的升温的发光元件灯和照明设备。 本发明提供一种发光元件灯1,其包括:导热反射器2,具有发射开口部分,并形成为朝向发光开口部分加宽,反射面2a设置在内表面侧和外周面 暴露在外面; 经由盖3连接到反射器2的基座4; 设置在反射体2的内周面并与反射体2热连接的导热性散热构件8; 具有安装在其上的发光元件6并且附接到散热构件8的基板7,基板表面在表面接触状态下热连接到散热构件8; 容纳在盖3中以点亮发光元件6的照明电路9; 以及用于覆盖反射器2的发射开口部分2c的半透明盖5。
