1. A light device, comprising:
a cover configured to transmit light;
a light emitter disposed in the cover and including a first end, a second end, and an intermediate region disposed between the first end and the second end; and
a power board configured to supply power to the light emitter,
wherein the light emitter comprising:
light sources including a first light source and a second light source that are closest, among the light sources, to the first end and the second end, respectively, each of the light sources including a first contact electrode and a second contact electrode;
a first electrode pad electrically connected to at least one of the first contact electrodes of the light sources;
a second electrode pad electrically connected to at least one of the second contact electrodes of the light sources;
a wavelength converter configured to convert a wavelength of light emitted from at least one of the light sources, and
a connection line disposed on an insulation layer and electrically connected to the first electrode pad or the second electrode pad that is electrically connected to the light sources,
wherein a first distance measured as a shortest distance between the first light source and a first region of the cover is different from a second distance measured as a shortest distance between the second light source and a second region of the cover.
