Abstract: A full spectrum light emitting lamp and one or more translucent base bodies surrounding the lamp are disposed in the lighting apparatus, the one or more translucent bas bodies having a photocatalytic reaction layer which bears a photocatalyst made of a titanium dioxide thin film therein, or the one or more translucent base bodies having the photocatalytic reaction layer which bears the photocatalyst made of the titanium dioxide thin film therein and having infrared light-absorbing functions, and a space through which air can flow is formed between the lamp and the translucent base body. Therefore, an ultraviolet light, a visible light and an infrared light can effectively be utilized according to characteristics such as an air purifying function of the ultraviolet light, a lighting function of the visible light, and a heating function of the infrared light to thereby save optical energy emitted from the lamp. Further, forced convection is generated in the air flow space by a heating effect of the infrared light emitted from the lamp in addition to a heating effect of the optical energy emitted from the lamp, so that the air can sufficiently be ventilated to promote an air purifying effect.
