A luminous lamp having an ultraviolet filtering and explosion-proof thin film is disclosed. An outside of a lamp is coated by a transparent layer which comprises phosphor powder. Energy generated by the lamp is absorbed by the phosphor powder while the lamp is shining. The phosphor powder would release energy to shot brilliance, so as to provide auxiliary lighting after turning off the lamp. Additionally, the phosphor powder can absorb harmful ultraviolet and other harmful radiations with shorter wavelengths to be one part of the thin film for filtering harmful radiations. The harmful ultraviolet can be transformed by the phosphor powder into visible light to red shift radiations with short wavelengths; hence the harmful radiations with shorter wavelengths can be eliminated. The illumination of visible light can be further increased. The transparent layer can catch broken fragments of the outside of the lamp to decrease accidents when the lamp is broken.
