    The light intensity can be explained by the heat generation that takes place between the mercury core which emits the radiation and the direct contact with the connection of the lamp in the glass tube.
    BRIEF DESCRIPTION OF THE INVENTION The object of the present invention is to optimize the function of the UV lamps used in the treatment process due to variations in the environment regarding operating temperatures.
    This object is achieved with the features of the independent claims. Preferred embodiments of the present invention are found in the subclaims.
    According to a main aspect of the invention, it is characterized by a device to be used with a liquid treatment device, which liquid treatment device comprises a casing having an enclosure, an inlet and an outlet arranged to said casing for providing a liquid flow through said enclosure to UV radiation. said housing and arranged in said enclosure, capable of emitting radiation in the range of 130 nm to 400 nm, the device comprising a temperature control circuit arranged in the vicinity of the attachment of the lamp to the housing and capable of controlling the temperature around the attachment of said lamp.
    According to another aspect of the invention, it is characterized in that the temperature control circuit comprises a protective device.
    According to a further aspect of the invention, it is characterized in that the spring medium comprises a resistance circuit.
    According to another aspect of the invention, it is characterized in that the temperature control circuit comprises a cooling device.
    According to yet another aspect of the invention, it is characterized in that said temperature control circuit further comprises a temperature meter capable of measuring the temperature around the attachment of the lamp. Preferably, said temperature control circuit comprises a microprocessor capable of controlling the temperature.
    The advantages of the present invention are yours. Thanks to the present invention, the temperature of a UV-generating lamp is controlled in such a way that the optimum operating temperature is maintained, whereby the light intensity is maximized.
    The liquid treatment device can thus be used both for hot and cold liquids and in hot or cold environments.
    Since the temperature is controlled around the attachment of the lamp, the temperature closest to the lamp, which affects the effect of the lamp the most, is controlled in the most efficient way.
    The control circuit preferably uses a temperature meter to measure the temperature around the mounting, which temperature measurements are used to control the amount of heat or cold to the lamp.
    When the lamp is to be heated, a resistance circuit can be used, which has low power consumption. Preferably, a microprocessor is used to control the temperature control circuit. The microcontroller. can be programmed to function in different ways and with additional devices and functions connected to the temperature control device. For example, it may be your temperature meter arranged to the device, such as to measure the liquid inside the enclosure, i.e. the temperature of the liquid to be treated. Furthermore, the microcontroller may comprise energy measuring means instead of measuring the energy consumption of the heating / cooling devices to regulate and control the energy in order to avoid overloading of components.
    These and other aspects and advantages of the present invention will become apparent from the following detailed description and the accompanying drawings.
    BRIEF DESCRIPTION OF THE DRAWING FIGURES In the detailed description of the invention, reference will be made to the accompanying drawings, in which Fig. 1 is called the water treatment, shows a diagram of a UV lamp commonly used in Fig. 2 invention, and shows an example of a water purification unit comprising the present Fig. 3 treatment unit. shows a detailed view of the present invention connected to a DETAILED DESCRIPTION OF THE INVENTION As shown in Figure 1, the intensity of a UV lamp depends on the temperature surrounding the lamp. An ideal temperature range would be in the range of 25 - 30 degrees Celsius.
    To ensure this, the present invention has been developed and will be described in connection with an example of a water purification unit marketed and sold by the applicant for the present invention.
    The treatment unit according to Fig. 2 comprises a substantially elongate tube 10, which creates a treatment space and which has an inlet 12 and an outlet 14.
    Inside the treatment space a quartz glass tube is arranged (not shown), inside which a lamp is arranged. The lamp is capable of generating light in the UV range, ie. in the range 150 to 400 nm. The lamp is connected to an end piece 16, which in turn is removably connected to the tube 10.
    The lamp is further connected to a drive unit 18 via a cable 20, which drive unit is capable of providing sufficient energy to the lamp to emit UV radiation inside the treatment space. For this purpose, the drive unit is connected to a power source via a power cable 21. The end piece to which the lamp is connected is in many cases made of metal such as brass, aluminum or the like. According to the invention, it comprises a temperature control circuit 22, Fig. 3. The temperature control circuit comprises a microprocessor 24 with a function which will be described below.
    The temperature control circuit is connected to a power source via a cable 25.
    The temperature circuit further comprises a heater 26 connected to the end piece 16 and capable of emitting heat to the connection between the lamp and the end piece. The heater may, for example, be a resistance circuit which heats the immediate surroundings of the metal bracket when driven by the microprocessor. However, it should be understood that other types of spring organs may be used. However, it is advantageous if the heating circuit is low consuming.
    The temperature control circuit 22 further preferably includes a temperature gauge 28 connected to the microprocessor and capable of measuring the temperature around the mount.
    Thus, the microprocessor activates or deactivates the heating circuit depending on the temperature measured by the temperature meter 28. In the above embodiment a heating element has been discussed but it should be understood that also a cooling device can be used instead of, or together with, the heating circuit, depending on the application. simplest example may be a fl genuine 30, but it should be understood that a circuit with cooling media can be connected to the lamp holder. For example, if the treatment unit is to be used to treat hot liquids or is located in a hot environment, the lamp needs to be cooled instead.
    In addition, both a protection circuit and a cooling circuit can be provided to the lamp if the treatment unit is used in both hot and cold environments.
    It is to be understood that the embodiments of the invention described above and shown in the drawings are to be considered as non-limiting examples of the invention only and that it may be modified in many ways within the scope of the claims.
