A lighting unit according to one embodiment includes a board, a support member, and a plurality of heat radiation fins. A light emitting element is disposed on a first surface of the board. The support member has an interior surface on which a second surface of the board that is opposite to the first surface is disposed to be in contact therewith to enable heat conduction from the board to the support member. The heat radiation fins are disposed on an exterior surface of the support member substantially parallel with each other and with a clearance between each other, and each having a flat shape that extends outwardly from the exterior surface.

Lighting unit and lighting device

A light emitting module () comprises a module substrate (), a light emitting diode string (), and a sealing member (). The light emitting diode string () includes light emitting diode elements () and bonding wires () which connect the light emitting diode elements (). The light emitting diode element () has a pair of element electrodes () and has a rectangular shape extending in a direction along which the element electrodes () are aligned. The sealing member () is laminated on the module substrate () to seal the light emitting diode string (). The light emitting diode elements () are arranged at intervals in a direction crossing the direction along which the element electrodes () are aligned, and the element electrodes () with the same polarity are aligned to be adjacent to each other in an arrangement direction of the light emitting diode elements () between the light emitting diode elements () adjacent to each other. Each bonding wire () is obliquely wired with respect to the arrangement direction of the light emitting diode elements () to connect the element electrodes () with different polarities of the light emitting diode elements () adjacent to each other.
