Abstract
A light-emitting module may be configured to have improved light emission efficiency and light distribution characteristics. A light-emitting module may include a substrate having a front surface side as a component mounting surface and a rear surface side as a flat heat dissipating surface, a plurality of light-emitting elements arranged in a manner protruding at a central portion of the component mounting surface of the substrate. The light-emitting elements may radiate light at least in an upper surface direction and in a direction along the component mounting surface. The module may further include one or more lighting circuit components electrically connected to the light emitting elements by a wiring pattern arranged on the substrate and which is arranged closer to the peripheral edge side of the substrate than the light emitting elements on the component mounting surface of the substrate, and a connector for power supply connection.
