  1 shows an example in which the number of LED modules 21 that can be mounted on the LED illumination unit 11 is three, but it is also possible to have one, two, or four or more, for example. .

  The nonvolatile memory 23 stores attribute data of the LED illumination unit 11 including the shape of the LED illumination unit 11 in a manufacturer that produces the LED illumination unit 11, for example.

  The connectors 22a to 22c, the memory 23, and the connector 24 are electrically connected, and the connector 24 is connected to the connector 56 of the lighting control device 12.

  The LED drive circuits 51a to 51c of the illumination control device 12 drive the LED chips 41a to 41c of the LED modules 21a to 21c, respectively, based on the control of the LED control circuit 52.

Further, the LED control circuit 52 reads the attribute data of the LED illumination unit 11 from the memory 23 of the LED illumination unit 11. Furthermore, the LED control circuit 52 acquires setting information for setting the LED light quantity, ON / OFF, external control setting by an external trigger, and the like, which are input by the user using the input device 53. Further, the LED control circuit 52 supplies data indicating the characteristics, temperature, state, and the like of each LED module 21 to the microscope apparatus 14 and the external control apparatus 15 as necessary. Further, the LED control circuit 52 acquires a control signal for instructing control of the lighting state of each LED chip 41 from the microscope device 14 and the external control device 15.

  The LED control circuit 52 includes setting information acquired from the input device 53, characteristic data and temperature data acquired from each LED module 21, driving current and driving voltage of each LED chip 41 acquired from the LED driving circuit 51, the microscope device 14 and Each LED drive circuit 51 is controlled based on a control signal supplied from the external control device 15.

  The epi-illumination unit 13 controls the optical path of the illumination light emitted by the LED illumination unit 11 or extracts a predetermined wavelength component from the illumination light, and is a specimen placed on a stage (not shown) of the microscope apparatus 14. Illuminate with illumination light. The epi-illumination unit 13 includes a filter turret that can be equipped with a plurality of filter cubes including filters such as a barrier filter and an exciter filter and can select a filter cube to be used. The epi-illumination unit 13 supplies data indicating the characteristics (for example, transmission wavelength) of the filter cube set to transmit the illumination light to the microscope apparatus 14.

  The microscope device 14 is a microscope capable of observing a specimen using epi-illumination light irradiated through the epi-illumination unit 13.

  The external control device 15 is configured by, for example, a PC (personal computer). The external control device 15 controls the microscope device 14 and the LED control circuit 52, acquires the specimen image observed by the microscope device 14 and data indicating the state of the microscope device 14, and displays the acquired image and data. To do.

  Next, the illumination control process executed by the microscope system 1 will be described with reference to the flowchart of FIG. This process is started, for example, when the illumination control device 12 is turned on.

  In step S1, the LED control circuit 52 reads the characteristic data of the LED modules 21a to 21c attached to the LED illumination unit 11 from the memories 42a to 42c.

  In step S <b> 2, the LED control circuit 52 reads the attribute data of the LED illumination unit 11 from the memory 23.

  In step S3, the LED control circuit 52 determines whether or not the shapes of the LED modules 21a to 21c are compatible with the LED lighting unit 11 based on the module shape data of the LED modules 21a to 21c and the attribute data of the LED lighting unit 11. Determine whether. If it is determined that the shape of the LED modules 21a to 21c is compatible with the LED illumination unit 11, the process proceeds to step S4.

  In step S4, the LED control circuit 52 determines whether or not interlock control is necessary. Specifically, the LED control circuit 52 detects that at least one of the LED modules 21a to 21c is irradiated with light having a risk of adversely affecting the human body, such as ultraviolet rays, based on the LED type data. In this case, it is determined that interlock control is necessary, and the process proceeds to step S5.

  In step S5, the microscope system 1 performs interlock control. Specifically, the LED control circuit 52 of the illumination control device 12 from the microscope device 14 has an optical path setting in which the illumination light emitted from the LED illumination unit 11 reaches the eyepiece of the microscope device 14. Is input. If the LED control circuit 52 detects that the light path is set so that the illumination light reaches the eyepiece of the microscope apparatus 14 based on the signal, the risk of adversely affecting the human body among the LED chips 41a to 41c. The LED drive circuits 51a to 51c are controlled so as not to turn on the LED chip that emits the characteristic light. As a result, it is possible to prevent the user's eyes and the like from being accidentally irradiated with light having a risk of adversely affecting the human body. Thereafter, the process proceeds to step S6.

  On the other hand, when it is determined in step S4 that the interlock control is not necessary, the process of step S5 is skipped, and the process proceeds to step S6.

  In step S6, the LED control circuit 52 sets a maximum current value. Specifically, the LED control circuit 52 controls each LED drive circuit 51 so that the maximum value of the drive current that drives each LED module 21 is equal to or less than the rated value indicated by the maximum current data of each LED module 21. Set. Thereby, the variable range of the drive current flowing through each LED module 21 is automatically set without manually setting the rated value of the drive current. Further, it is possible to prevent the LED chips 41a to 41c from being broken due to the drive current exceeding the rated value flowing regardless of the drive current of the LED chips 41a to 41c.

  In step S7, the LED control circuit 52 sets the maximum drive voltage. Specifically, the LED control circuit 52 sets the voltage applied to each LED module 21 based on the forward voltage data of each LED module 21 to an optimum voltage for driving each LED module 21. In addition, each LED drive circuit 51 is controlled. Thereby, for example, when linear constant current control is performed on each LED module 21 in order to reduce flicker noise of illumination light, the driving voltage of each LED module 21 can be optimized, and each LED module 21 can be optimized. Heat generation of a constant current circuit (not shown) of the drive circuit 51 can be suppressed.

  In step S8, the LED control circuit 52 determines whether or not characteristic data is requested. When the LED control circuit 52 determines that the characteristic data is requested from the external control device 15, the process proceeds to step S9.

  In step S <b> 9, the LED control circuit 52 transmits the characteristic data of each LED module 21 to the external control device 15.

  In step S10, the external control device 15 performs processing based on the characteristic data. For example, the external control device 15 reads out from the microscope device 14 data indicating the characteristics of the currently set filter cube of the incident illumination light. The external control device 15 displays the transmission characteristics of the filter cube and the wavelength characteristics (for example, center wavelength, half-value width, etc.) of each LED chip 41. Thereby, it can be easily confirmed whether or not the combination of the LED chips 41a to 41c and the filter cube is appropriate, and it is possible to prevent the wrong combination from being used.

  Further, for example, when the LED chip 41a to 41c includes a white LED, the external control device 15 displays the color temperature of the LED chip 41. Since the white LED has a large variation in color temperature, for example, when the color tone of illumination light is to be adjusted by a plurality of microscopes, the LED module 21 having the same color temperature in each microscope can be selected by displaying the color temperature. Becomes easier.

  Thereafter, the process proceeds to step S11.

  On the other hand, if it is determined in step S8 that the characteristic data is not requested, the processes in steps S9 and S10 are skipped, and the process proceeds to step S11.

  In step S <b> 11, the LED control circuit 52 acquires measurement data of each LED module 21. Specifically, the LED control circuit 52 acquires temperature data of the LED modules 21a to 21c from the temperature sensors 33a to 33c. Further, the LED control circuit 52 acquires data indicating the values of the drive currents and drive voltages of the LED chips 41a to 41c from the LED drive circuits 51a to 51c.

  The LED control circuit 52 is based on the temperature of the LED substrate 31a detected by the temperature sensor 33a, the thermal resistance between the junction of the LED chip 41a and the temperature sensor 43a, and the driving voltage and driving current of the LED chip 41a. The temperature of the LED chip 41a is calculated. The LED control circuit 52 similarly calculates the temperatures of the LED chips 41b and 41c.

  In step S12, the LED control circuit 52 determines whether measurement data is requested. When the LED control circuit 52 determines that the measurement data is requested from the external control device 15, the process proceeds to step S13.

  In step S <b> 13, the LED control circuit 52 transmits measurement data, that is, data indicating the drive current, drive voltage, and temperature of the LED chips 41 a to 41 c to the external control device 15.

  In step S14, the external control device 15 records the measurement data. Specifically, the external control device 15 calculates the light emission wavelength of each LED chip 41 based on the temperature coefficient data of the temperature of each LED chip 41 and the light emission wavelength. Further, the external control device 15 calculates the light emission output of each LED chip 41 based on the temperature of each LED chip 41 and the temperature coefficient data of the light emission output. The external control device 15 records the drive current, drive voltage, temperature, emission wavelength, and emission output of each LED chip 41 together with the current time.

  Thus, by recording the measurement data relating to the LED chips 41a to 41c in time series, for example, in the different microscope system 1 or the same microscope system 1, the same observation condition (illumination intensity) is reproduced later, and the specimen It becomes easy to observe.

  The light emission output of the LED has a large individual difference compared to a light source such as a halogen lamp, and there is a large variation even with the same model number. Further, the brightness of the illumination at the time of observation when the LED is incorporated in the illumination device of the microscope is approximately proportional to the light emission output of the LED and the drive current of the LED, and is expressed by the following equation (1).

  Lighting brightness 明 る LED emission output × LED drive current (1)

  For example, in an environment where there are a plurality of microscopes having the same configuration, there is a case where it is desired to observe a specimen by reproducing observation conditions performed on one of them with another microscope. In this case, by calculating the drive current B of the LED of the microscope B having the same configuration as the microscope A based on the information on the light emission output A and the drive current A of the LED in the reference microscope A, the LED is driven, The specimen can be observed under almost the same observation conditions as the microscope A. At this time, the driving current B of the microscope B can be calculated by the following equation (2).

  Drive current B = drive current A × light emission output A / light emission output B (2)

  Here, more specifically, a specimen in another microscope system 1 (hereinafter referred to as microscope system 1B) under the same observation condition as that observed with one reference microscope system 1 (hereinafter referred to as microscope system 1A). Consider the case of observing.

  In this case, by supplying the measurement data A recorded in the external control device 15A of the microscope system 1A to the microscope system 1B, the LED control circuit 52 of the microscope system 1B causes the light emission output A and the LED chip 41 of the microscope system 1A and Time series data of the drive current A can be obtained. Further, as described above, the LED control circuit 52 of the microscope system 1B can obtain the temperature data of its own LED chip 41, and calculates the light emission output B of its own LED chip 41 based on the obtained temperature data. can do. Then, the LED control circuit 52 of the microscope system 1B calculates the drive current B for driving its own LED chip 41 based on the calculated light emission output B using the above-described equation (2), and calculates the calculated drive current. The LED drive circuit 51 is controlled so that B flows through the LED chip 41.

  Thereby, the observation conditions in the microscope system 1A can be reproduced almost accurately in the microscope system 1B. In other words, the specimen can be observed with the same image brightness even if there is a time interval and a difference between the microscopes. Further, by illuminating the specimen with substantially the same amount of illumination, for example, in fluorescence observation using LED illumination, it is possible to control the influence of fading of the specimen due to excitation light to the same level.

  In the same way, when the same observation condition is reproduced with time in one microscope system 1, the observation condition can be reproduced almost accurately in the same manner.

  Note that the emission wavelength and emission output of each LED chip 41 can be calculated later if there is temperature of each LED chip 41 and temperature coefficient data of the emission wavelength and emission output. Therefore, instead of the light emission wavelength and the light output of each LED chip 41, the light emission wavelength of each LED chip 41 and the temperature coefficient data of the light output may be recorded together with other measurement data.

  Further, the external control device 15 may display the measurement data as necessary. Further, instead of the external control device 15, the LED control circuit 52 may calculate and record all measurement data.

  Thereafter, the process proceeds to step S15.

  On the other hand, when it is determined in step S12 that the measurement data is not requested, the processes in steps S13 and S14 are skipped, and the process proceeds to step S15.

  In step S <b> 15, the illumination control device 12 drives each LED chip 41. Specifically, the LED control circuit 52 acquires setting information input by the user using the input device 53. The LED control circuit 52 sends a command to the LED drive circuits 51a to 51c based on the acquired setting information, and the LED drive circuits 51a to 51c control lighting of the LED chips 41a to 41c based on the command. Further, the LED drive circuits 51a to 51c reduce the drive current and suppress the heat generation of the LED chips 41a to 41c when the temperature of the LED chips 41a to 41c calculated by the LED control circuit 52 is high.

  In step S16, the illumination control device 12 displays the current state. Specifically, the LED control circuit 52 supplies characteristic data, measurement data, and data indicating the lighting state of each LED module 21 to the display unit 54, and the display unit 54 displays the acquired data. The type of data displayed at this time is selected and set by the user in advance, for example.

  Thereafter, the process returns to step S1, and the processes of steps S1 to S16 are repeatedly executed until the illumination control device 12 is turned off.

  On the other hand, if it is determined in step S3 that at least one of the LED modules 21a to 21c is not suitable for the LED illumination unit 11, the process proceeds to step S17.

  In step S <b> 17, the display unit 54 displays shape incompatibility. That is, the display 54 displays a message notifying that at least one of the LED modules 21a to 21c is not compatible with the LED illumination unit 11 under the control of the LED control circuit 52. Thereafter, the LED chips 41a to 41c are not driven, and the illumination control process ends.

  As described above, the LED that is the light source of the illumination light of the microscope system 1 can be easily replaced and used. In other words, the newly installed LED module 21 can be appropriately driven and used simply by installing the LED module 21 without performing any special settings.

  Further, by modularizing the LED, it becomes easy to replace the LED, and the wavelength of the illumination light to be used can be easily changed. Furthermore, for example, when a high-brightness, high-power LED chip is newly released, it can be modularized in the same way as the LED module 21 so that a new LED chip can be used regardless of differences in the specifications and shape of the LED chip. The LED illumination unit 11 can be attached and used.

  Note that wireless communication such as RFID (Radio Frequency IDentification) may be used for reading the characteristic data of the LED module 21.

  Moreover, although the example in the case of performing epi-illumination control was shown in the above description, this invention can also be used for control of illumination (for example, transmission illumination) other than epi-illumination.

  Furthermore, in the above description, an example of controlling illumination using an LED as a light source has been shown, but the present invention can also be applied to controlling illumination using a light source other than an LED. .

  Further, the above-described processing related to the control of the LED control circuit 52 by the external control device 15 may be performed by the LED control circuit 52 itself.

  The embodiment of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.
