LIGHTING DEVICE AND LIGHTING EQUIPMENT

摘要

Provided is a lighting device in which heat dissipation properties are improved without obstructing the dissipation of heat from a light-emitting element. The lighting device (1) comprises: a plurality of light source units (30) having a light-emitting element substrate (12); a power supply unit (16) that is sandwiched by the light source units (30) in the substrate surface direction of the light-emitting element substrate (12) and that accommodates a circuit substrate (163) for supplying power to a light-emitting element (11); and a light source unit support member (17) that has the power supply unit (16) fixed thereto and that supports the light source units (30). The circuit substrate (163) is arranged more on the light source unit support member (17) side than on the light-emitting substrate (12) side in an internal space in the power supply unit (16).
