1. A hidden lighting lamp comprising:
a light source;
a lens projecting light of the light source to an outside of the hidden lighting lamp; and
a color conversion member spaced apart from the light source by a first air gap to form a transmission path of light energy emitted from the light source,
wherein the color conversion member includes a phosphor layer having a fluorescent material and a front-phosphor layer between the phosphor layer and the lens,
wherein the front-phosphor layer forms an integrated structure or a separated structure with respect to the lens,
wherein the front-phosphor layer is modified into any one of a deposition layer, a painting layer, a top coating layer, a color painting layer, and a base coating layer, and
wherein a light transmission hole is formed in each of the deposition layer, the coating layer, the top coating layer, the color coating layer, and the base coating layer to increase light transmittance.
