Disclosed is a lens for a vehicle including a light source part including a plurality of light sources that irradiate light, and a lens part that outputs the light irradiated by the light source part to a front side, and the lens part includes a first lens disposed on a front side of the light source part, and a thickness of which becomes smaller as it goes toward opposite sides with respect to a leftward/rightward direction, and a second lens disposed on a front side of the first lens and deflected to be disposed on a more rear side as it goes from one end to an opposite end thereof with respect to the leftward/rightward direction.

A hidden lighting lamp uses a color conversion material and is applied to a vehicle. A color conversion member is spaced apart from a light source by a light source air gap (La) such that the color conversion member is integrally engaged with a lens for projecting light of the light source to the outside or such that the color conversion member is spaced apart from the lens by a lens air gap (Lb). Hidden lighting without deterioration of optical efficiency of LED light from the light source is thereby implemented. One or more of a black painting, a coating layer, an application layer, and a deposition layer are provided, thereby providing concealment of the lamp inner space of the lens, anti-peeling of a deposit, and diversity of fluorescent color.

A rotation light source lamp system is combined with a rotation light source device in which a chromatic aberration correction unit obviates focal distance differences occurring between incident paths “a” of lights emitted by LED light sources sequentially synchronized and turned on when first to N-th LED chips arrive at a location where each LED chip faces a signal transmitter while the first to N-th LED chips are rotated once in response to the application of a lamp turn-on signal for the vehicle from the signal transmitter. Chromatic aberration can be reduced by correcting a difference between refractive indices for each wavelength having a different color in the first to N-th LED chips.

A rotation adjustment mechanism includes a rotation target module supported to be freely rotatable with respect to a fixation member around a first rotary shaft and an adjustment unit including a slider. Rotation of the rotation target module around the first rotary shaft is regulated by a contact point where a connection groove of the rotation target module and a projection part of the slider contact each other, and a shape of a surface of the connection groove contacting the projection part is a shape formed by a locus that successively connects the contact points of the connection groove and the projection part each of which is obtained each time the rotation target module is moved around the first rotary shaft by a unit angle and simultaneously the projection part fixed to the slider is translated by a constant amount in a direction parallel to the slide axis.
