Abstract
Disclosed is a lighting device which comprises: an optical member comprising a protruding optical pattern forming a gap with an adjacent layer; at least one light emitting unit inserted into the optical member; and a resin layer formed on the optical member and the at least one light emitting unit, whereby it is possible to obtain an effect that the shapes of light change depending on the viewing angle when viewing the light source by producing various protruding optical patterns, an effect that the whole thickness can be reduced, and an effect that the degree of design freedom can be enhanced when designing products thanks to an enhanced flexibility.
