Abstract
According to one embodiment, an illuminating device includes a wiring substrate, light emitting elements, a wavelength conversion element, and a protrusion. A main surface of the wiring substrate is divided into segment areas. N light emitting elements are disposed in each of the segment areas. N is greater than 1. The light emitting elements are driven independently in units of the segment areas. The protrusion protrudes from the wiring substrate toward the wavelength conversion element between two segment areas adjacent to each other.
