Description

UV chamber equipped with an automatic position-adjusting photometer and a method for measuring UV light intensity using the same

[0001] The present invention relates to a UV chamber equipped with an automatic position-adjusting photometer, and more specifically, to a UV chamber equipped with a lamp that selectively illuminates UV-A, UV-B, and UV-C, and a light blocking part that can be quickly and automatically opened and closed to ensure that UV light is irradiated to a sample for an accurate period of time, and a UV detection device that can move up, down, left, and right to measure and apply an accurate UV light amount at a location where a sample is placed, and a method for measuring UV light amount using the same.

[0002] The UV chamber of the present invention is a device for studying biochemical reactions, etc., due to UV irradiation on samples such as microorganisms and mammalian cells cultured in a culture device, and is commonly used in laboratories for various purposes, such as studying the effect of UV on the reaction of cultured microorganisms and cells, inducing DNA damage in cells, binding DNA or RNA to a membrane in biological experiments, and sterilizing laboratory equipment.

[0003] In a UV chamber, important factors include the type, time, and location of light, and these factors must be adjustable depending on the sample being irradiated. Conventional UV chambers or irradiators place the sample to be irradiated on a stage located within a housing, and irradiate it by moving the upper and lower sources that emit ultraviolet light on the stage. The upper and lower sources irradiate UV corresponding to UV-A, UV-B, or UV-C to the sample. However, the above conventional technology does not allow for the determination of whether UV light is being irradiated. This requires the user to manually measure the UV light intensity at various locations within the UV chamber using a UV light meter. This direct measurement by the user not only makes it difficult to monitor the UV light intensity for a long time, but can also delay the measurement time and result in inaccurate measurements.

[0004] In addition, since there is no separate blocking section inside the UV chamber capable of blocking the light irradiating thereon, the UV transmitted to the sample is manually blocked using a material that does not allow the light to pass through, or the user directly turns off the power to the UV source (UV lamp), or the UV light is blocked by manually opening and closing a sliding door-type blocking screen. Therefore, there is a need to develop a UV chamber capable of providing the correct amount of UV light from the sample.

[0032] Referring to the drawings, the UV irradiator is configured as a chamber-shaped device for studying biochemical reactions of cells, etc. according to UV irradiation using microorganisms, mammalian cells, etc. cultured in a culture device. The UV irradiator comprises a lighting device (100) including a UV lamp that irradiates UV light into the inside of the UV chamber (10), a light blocking unit (200) located below the lighting device (100), a table (500) for placing the sample inside the UV chamber (10), a UV detection device (300) located above the sample and moving the table to measure the amount of UV light, a UV shielding screen (400) located above the table and covering the UV detection device (300) from the lighting device (100), and a control unit (600) for controlling the light blocking unit (200) and the UV detection device (300).

[0033] An opening (700) consisting of one door or one or more windows is provided on the front of the UV chamber (10) so that the UV chamber (10) can be opened and closed. The opening (700) allows a sample to be placed inside the UV chamber (10) and the sample to be discharged after irradiation is completed. The opening (700) can be opened in any one of the up, down, left, or right directions.

[0034] The above lighting device (100) is connected to and mounted on the upper surface of the UV chamber (10), and a UV lamp (not shown in the drawing) is installed inside the UV chamber (10) to irradiate UV light into the inside of the UV chamber (10). The UV lamp can change the type of light depending on the purpose of irradiation, and the type of UV lamp can be selected from among UV-A, UV-B, and UV-C, and the UV light can be replaced as needed. The UV lamp can be replaced with a necessary UV lamp each time the sample is observed, and after each type of UV lamp is installed in the lighting device (100) as a replacement, a desired UV light can be selected through the control unit (600) and irradiated to the sample.

[0035] The above light blocking unit (200) is installed at the bottom of the lighting unit (100) to control the amount of UV light irradiated from the lighting unit (100) into the UV chamber (10). The light blocking unit (200) can have its opening and closing time controlled by the control unit (600) to control the amount of UV light irradiated to the sample, and the light blocking unit (200) can be configured in various ways depending on its shape.

[0036] The light blocking unit (200) may be controlled by a solenoid blocking method that can open and close the light blocking unit (200) using a solenoid, a rotating plate method that can reduce or increase the area of ​​the formed hole by rotating either a plate in which a hole is formed or a plate covering the upper and lower portions of the hole, and thus control the amount of UV light irradiated from the sample, or a slide shutter method that can control the amount of UV light temporally by forming an opening and closing port and controlling the opening and closing port with a slide type, and controlling the shutter time of the opening and closing port, and so on. The light blocking unit (200) may be performed by selecting any one of the following methods.

[0037] Fig. 3 is a drawing showing the inner side of a UV chamber according to one embodiment of the present invention, and Fig. 4 is a drawing showing the upper surface of the inside of a UV chamber equipped with an automatic position adjustment UV detection unit according to one embodiment of the present invention. Referring to the drawings together, the table (500) is installed inside the UV chamber (10) and is formed parallel to the lower surface of the UV chamber (10), and allows a sample to be studied to be placed on the upper surface of the table (500).

[0038] The above table (500) can be mounted one or more times inside the UV chamber (10), and is coupled with a z-axis guide (800c) installed inside the UV chamber (10) so as to be able to move up and down along the z-axis guide (800c). In addition, by moving the table (500) up and down, the gap between the UV detection device (300) and the sample positioned above the table (500) can be adjusted.

[0039] The UV shield (400) is positioned above the table (500) and is positioned parallel to the lower surface. The UV shield (400) can be used in a fixed state for the purpose of protecting the UV detection device (300) when the UV lamp irradiates UV light to the sample. In addition, when the UV detection device (300) is not in use, the UV detection device (300) can be hidden under the light blocking part (200) to block UV light irradiated from the lighting device (100). This allows the UV detection device (300) to be moved to the lower part of the UV shield (400) to avoid UV light in order to avoid measuring unnecessary UV light amounts.

[0040] The UV detection device (300) is positioned between the table (500) and the light blocking unit (200), and functions as a UV photometer that measures the amount of UV light provided to the sample. The UV detection device (300) can move in the x-axis and y-axis through the x-axis guide (800a) and the y-axis guide (800b) above the sample located on the upper surface of the table (500), and the movement can be controlled from the control unit (600). FIG. 5 is a drawing showing the order in which the UV detection unit moves to measure the amount of UV light according to one embodiment of the present invention, and shows the upper surface inside the UV chamber (10). When the table (500) is divided into three equal parts by the x-axis and y-axis, and is configured as a total of nine sections, the UV detection device (300) moves in the x-axis direction from 1 to 2 and then 3, and then moves to specific positions on the x-axis and y-axis in the order of 4, 5, 6, 7, 8 and 9 to measure the amount of UV light, and, if necessary, moves along the z-axis to measure the amount of UV light.

[0041] The control unit (600) controls the opening and closing of the light blocking unit (200) and controls the position of the UV detection device (300). In addition, when the UV lamps are configured in multiples and one lamp is irradiated, a desired UV lamp can be irradiated through the control unit (600), and the opening and closing time of the light blocking unit (200) can be controlled or the irradiation time of the lighting device (100) can be controlled so that the amount of UV light transmitted to the sample is constant, and the UV detection device (300) can be operated or stopped to measure the amount of UV light.

[0042] Hereinafter, a UV light intensity measurement method using the UV chamber (10) according to an example of the present invention will be described. The measurement method of the present invention can utilize the above-described UV chamber (10), and descriptions of content overlapping with the above-described UV chamber (10) will be omitted.

[0043] FIG. 6 is a flowchart illustrating a method for measuring UV light intensity using a UV chamber equipped with an automatic position-adjusting UV detection device according to an embodiment of the present invention. Referring to FIG. 1, a sample to be observed is placed on a table (500) inside a UV chamber (10). Then, power is supplied to the UV chamber (10) to prepare for measurement, motion, control, etc. After reading and initializing the current status values ​​of measurement, motion, control, etc., a UV light irradiation step (S100) in which a UV lamp inside a UV lighting device (100) irradiates UV light to a sample inside the UV chamber (10), a light blocking unit control step (S200) in which the opening and closing of the light blocking unit (200) is controlled to adjust the amount of UV light provided to the sample, and a UV light amount measurement step (S300) in which a UV detection device (300) located above the sample moves to measure the amount of UV light provided to the sample from the UV lamp are performed.

[0044] In the above UV ray irradiation step (S100), the UV lamp irradiates UV rays to the sample, and the UV lamp further includes a step (S110) of selecting one of UV-A, UV-B, and UV-C, which can be performed by turning it on / off in the control unit (600) or by the user replacing the lamp.

[0045] In the above light blocking unit control step (S200), the light blocking unit (200) can control the opening and closing of the hole of the light blocking unit (300) through which UV light passes from the control unit (600).

[0046] In order to measure the amount of UV light, the UV detection device (300) can move in the x-axis and y-axis through the x-axis guide (800a) and y-axis guide (800b) from the upper portion of the sample to measure the amount of UV light, and, if necessary, move in the z-axis along the z-axis guide (800c) to enable measurement of the amount of UV light at all positions. In addition, when irradiating an actual sample, the UV detection device (300) can move to the bottom of the UV shield (400) to avoid irradiation of unnecessary UV light.

[0047] When the measurement is completed, the control unit (600) outputs the results such as charts, dose maps, and analysis-result reports, and saves the results of tasks such as measurement, processing, and analysis and the output results.

[0048] While the embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without altering the technical spirit or essential characteristics thereof. Therefore, the embodiments described above should be understood to be illustrative in all respects and not restrictive.
