  • Patent number: 11788691
    Abstract: 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.
