The invention provides an ultraviolet irradiation device which has an excimer lamp and can surely detect whether the excimer lamp is lit up or not. The ultraviolet irradiation device is provided with a discharge container, an excimer lamp and a power supply device, wherein, at least part of the discharge container is formed by dielectric medium material which can transmit ultraviolet rays and gasfor discharging is filled in the inner discharging space; the excimer lamp is provided with a pair of electrodes which are arranged face to face across the dielectric medium material of the dischargecontainer; the power supply device is connected with the pair of electrodes and used to supply the excimer lamp with power. The ultraviolet irradiation device is characterized in that the power supply device is connected electrically with at least one end of any electrode. The ultraviolet irradiation device is provided with a light guiding part, a light receiving part and a lightingup detecting component, wherein, in an effective lighting area, the light guiding part is configured correspondingly in the area which is more closer to the other end of the electrode than the end connected with the power supply device, so that the light which is emitted by the excimer lamp and entered from one end of the electrode can be emitted from the other end; the light receiving part is used to receive the light emitted from the light guiding part.
