An apparatus (1) for irradiating material comprises a single UV, pulsed brigth white light or IR lamp (2) with a centrally disposed receptacle (3) for containing material to be irradiated. The lamp can be an elongate hollow tube (2) of annular construction. Internal formations may be present within the lamp to control the position of the arc. For example, the lamp may have a plurality of longitudinal segments arranged such that a discharge arc is formed within each segment or internal formations may be provided to direct the position of the arc within the lamp. A pump (36) may be included for moving material through the receptacle which is preferably the hollow area within the annulus of the elongate hollow tube. Material can be treated batchwise or in a continuous process. This apparatus is suitable for the sterilisation of biological and/or non-biological materials. A further use is in carrying out photolysis on chemical substances in photochemical reactions.
An irradiation apparatus (1) comprising a light emitter (2) for ultraviolet light, infrared light or pulsed bright white light in the form of a single linear lamp having a centrally disposed unimpeded hollow area and a receptac1e (3) for containing a material to be treated by irradiation positioned within the hollow area and in direct contact with the wall of the hollow area.
An apparatus as claimed n any one of the proceding claims, in which the lamp is a discharge lamp.
An apparatus as claimed in any one of the preceding claims, in which the light emitter is an ultraviolet light.
An apparatus as claimed in any preceding claim including cooling means (6) for controlling the temperature of the material to be treated.
An apparatus as claimed in any one of the preceding claims including a reflective jacket (4) for reflecting the generated light towards the receptacle.
An apparatus as claimed in any one of the preceding claims including shield means (5) for surrounding the lamp to prevent generated light escaping outwardly therefrom.
An apparatus as claimed in any one of the preceding claims including means for preventing intermingling of treated and untreated material.
An assembly (1) for treating a material by light irradiation comprising a single lamp (2) adapted to emit ultraviolet, infrared or pulsed bright white light of a desired wavelength, the lamp having a receptacle (20) for containing material to be treated and including an inlet and an outlet and means for supplying the material to the inlet and collecting treated material from the outlet, the passage between the inlet and the outlet being unimpeded.
