Description

[Technical field]

[0001] The present invention relates to a system for controlling light output, and more particularly to a system for controlling the light output of an optical device that includes a solid-state light source. [Background technology]

[0002] It is known that the actual light emission of solid-state light sources such as LEDs varies depending on the temperature of the solid-state light source, even when the same amount of current is input. Under such circumstances, a feedback control has been proposed as a technology for stabilizing the light output of LEDs, in which a part of the light emitted from the LED is received by a photosensor, and the amount of current supplied to the LED from the power supply circuit is adjusted based on the amount of light received.

[0003] However, in the case of feedback control using a photosensor, it is difficult to control the light output with high precision because the photosensor itself is affected by temperature, and the photosensor is also easily affected by other disturbances, making it difficult to follow short-term output fluctuations.

[0004] As a countermeasure to such problems, feedforward control has been proposed, in which the temperature of the LED is measured and the value of the current supplied to the LED is controlled in accordance with the value of the measured temperature (see, for example, Patent Document 1 below).

[0005] However, according to the method described in Patent Document 1, a data table is prepared in which the relationship between light output, temperature, and current is recorded in advance, and in order to realize a desired light output, a control is performed in which a current corresponding to a current value read from this data table is supplied to the LED. However, in order to precisely control the light output with this method, a huge amount of data needs to be recorded in the data table.

[0006] In addition, in order to determine the necessary amount of current, a process of reading data close to the desired light output and measured temperature from a data table and a supplementary process are required, and there is a limit to realizing a fast response. In particular, for a light source used in an application such as an endoscope in which the light output is expected to be finely adjusted during illumination, a fast response to the adjustment of the light output is required, so it is difficult to adopt the above control method.

[0007] From this perspective, the present inventor has proposed a technology that uses feedforward control and enables highly responsive optical output control while requiring less data than conventional control methods (see Patent Document 2 below). [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Japanese Patent Application Publication No. 3-36777 [Patent Document 2] JP 2022-133879 A Summary of the Invention [Problem to be solved by the invention]

[0009] The method proposed in Patent Document 2 is briefly described as follows. An execution control function that specifies the relationship between the temperature of the LED element, the applied current, and the light output is stored in advance. When the light source device is actually operated, information on the target light output is input, and the input target light output and information on the measured environmental temperature of the LED element are substituted into the execution control function to derive the applied current value that realizes the target output by calculation. Then, the amount of current is controlled so that the amount of current corresponding to the derived applied current value is supplied to the LED element. This allows the light source device to obtain a light output that approximately corresponds to the target light output.

[0010] Incidentally, the optical device side is usually equipped with an optical unit such as a filter and a lens, and the configuration of the optical unit often differs depending on the device. In particular, when a filter is installed, it is configured to transmit a specific wavelength range and suppress the transmission of another wavelength range, so it is expected that the emission spectrum of the LED element installed in the light source device and the spectrum of the light emitted from the optical device via the optical unit will be strictly different.

[0011] Since optical devices are intended to be used by irradiating light onto an object, it is important for users of optical devices to recognize the amount of light energy that actually contributes to the object. In other words, there is a reason to want to control the integral value of the light output over the wavelength range received by the object to a desired value, rather than the light output emitted by the LED element mounted on the light source device.

[0012] For this reason, even if the light output emitted from the LED element is controlled to a desired value based on the method described in Patent Document 2, the light output emitted through the optical unit may deviate from the desired value. Furthermore, depending on the object to be irradiated, the sensitivity may differ depending on the wavelength, so that even if the light output emitted from the LED element is controlled to a desired value, the light energy actually received by the object to be irradiated may deviate from the desired value.

[0013] The present invention has been made in consideration of the above problems, and has an object to provide an optical output control system that makes it possible to control the optical output to a desired level depending on how the optical device is used. [Means for solving the problem]

[0014] The light output control system according to the present invention is a system for controlling the light output of an optical device including a light source unit including a solid-state light source and a light source control unit that adjusts an amount of current supplied to the light source unit to control the light output of the light source unit, a first storage unit in which TIS data is recorded that defines a relationship between an optical output P1(λ) for each wavelength λ of the light source unit, an environmental temperature T1 of the light source unit, and an amount of current I1 supplied to the light source unit; A second storage unit in which sensitivity data is recorded regarding a sensitivity ratio D(λ) for each wavelength λ on an irradiation surface of an irradiation object when the light emitted from the light source unit is irradiated onto the irradiation object via an optical unit mounted on the optical device; a data creation unit that corrects the optical output P1(λ) included in the TIS data output from the first storage unit based on the sensitivity ratio D(λ) defined in the sensitivity data output from the second storage unit, derives corrected TIS data which is a relationship between the optical output P2(λ) for each wavelength λ on the irradiation surface of the irradiation object, the environmental temperature T1 of the light source unit, and the amount of current I1 supplied to the light source unit, and creates, by calculation, from the corrected TIS data, an integrated value Φ of the optical output P2(λ) over a specific wavelength range, and TIΦ data which is a relationship between the environmental temperature T1 of the light source unit, and the amount of current I1 supplied to the light source unit; a coefficient determination unit that determines a coefficient to be assigned to a control function by fitting the TIΦ data to a control function including a first variable corresponding to the integrated value Φ, a second variable corresponding to an environmental temperature T1 of the light source unit, and a third variable corresponding to an amount of current I1 supplied to the light source unit; The light source control unit is characterized in that it determines the amount of current to be supplied to the light source unit by applying a target value of the light output emitted from the optical device to the object to be irradiated and the environmental temperature of the light source unit mounted in the optical device to an execution control function in which the coefficient determined by the coefficient determination unit is assigned to the control function.

[0015] According to the above configuration, the sensitivity data, which is data on the light intensity according to the wavelength of the optical unit mounted on the optical device and / or the irradiation object irradiated with the light from the optical device, is recorded in the second storage unit. Specifically, the sensitivity data can be one or both of the transmission spectrum data of the optical system mounted on the optical device and the sensitivity spectrum data of the irradiation object.

[0016] Then, based on this sensitivity data, TIS data, which is data related to the characteristics of the light source unit mounted in the optical device, is corrected to generate TIΦ data. In other words, this TIΦ data is data that pseudo-indicates the relationship between the environmental temperature T of the light source unit, the amount of current I supplied to the light source unit, and the light output Φ received by the irradiation object. In other words, the TIΦ data is data that reflects not only the characteristics of the light source unit mounted in the optical device, but also the degree of light energy that actually contributes to the irradiation object.

[0017] Therefore, if the amount of current I obtained by substituting the environmental temperature T of the light source unit and the target light output Φ into the execution control function generated by fitting the control function to this TIΦ data is controlled to be supplied to the light source unit, it is possible to obtain a light output close to the light output that is actually desired to be irradiated to the object to be irradiated.

[0018] By recording the sensitivity data recorded in the second memory unit in advance according to the optical device and the object to be irradiated, it becomes possible to control the light output according to the purpose of the user who actually uses the optical device.

[0019] In this specification, the term "execution control function" refers to a function indicating a relationship expressed by multiple variables and a single or multiple specified coefficients, and a unique solution is determined by determining the values ​​of the variables. On the other hand, the term "control function" refers to a function indicating a relationship expressed by multiple variables and a single or multiple coefficients, but in a state where the values ​​of the coefficients have not been specifically determined. In other words, the "control function" is merely a concept that defines the "type" of a function, and is in a state where the relationship between each variable is not uniquely determined until the coefficients are determined. And a function in a state where the "single or multiple coefficients" defined under the control function are determined corresponds to an "execution control function".

[0020] The coefficient determination unit determines the coefficients and determines the function by fitting a control function with a specified function type based on the TIΦ data obtained by the data creation unit. This determined function is the execution control function. Any fitting method can be used, but the least squares method can be used as an example.

[0021] According to the above-mentioned light output control system, when the optical device is actually used, the light source control unit only needs to supply the light source unit with the current amount derived by simple arithmetic processing by inputting information on the target light output and information on the environmental temperature of the light source unit to the execution control function. Therefore, it is possible to control the light output with a small number of processes, and high responsiveness is obtained.

[0022] The solid-state light source included in the light source unit is assumed to be an LED element or an LD element. In particular, the LED element has a relatively large half-width and a peak wavelength that is easily affected by temperature, so the above control system is highly useful.

[0023] The environmental temperature of the light source unit mounted in the optical device may be, for example, a measurement value of a temperature detector mounted in the light source unit. The environmental temperature of the light source unit detected by the temperature detector may be the temperature of an area (substrate) on which the solid-state light source included in the light source unit is mounted, or may be the temperature of the solid-state light source itself. In addition, when the solid-state light source is disposed in a closed space, the environmental temperature may be the temperature of the atmosphere in the closed space.

[0024] In this specification, the term "specific wavelength range" refers to a wavelength range that serves the purpose of irradiating an object with light by irradiating the object with light from an optical device. In other words, in a situation where the light output is actually controlled using this system, the object is specified, and therefore a "specific wavelength range" is set according to the object. In other words, the integrated value Φ of the light output P2(λ) over the range of the specific wavelength range means the integrated value Φ of the light output P2(λ) over the range of the specific wavelength range set according to the object to be irradiated.

[0025] When the object to be irradiated with light using this system is predetermined, information about the specific wavelength range may be recorded in advance in a storage unit in the system. When candidates for the object to be irradiated with light using this system are predetermined, information about the specific wavelength range for each candidate may be recorded in advance in a storage unit in the system. Furthermore, the information about the specific wavelength range may be configured to be input from outside.

[0026] The optical output control system includes: a first server having the first storage unit; a second server having the second storage unit and installed at a location different from the first server, the data creation unit and the coefficient determination unit are mounted in the optical device, The data creation unit may create the TIΦ data based on the TIS data downloaded from the first memory unit of the first server and the sensitivity data downloaded from the second memory unit of the second server.

[0027] According to this configuration, the optical device reads information (TIS data) regarding the characteristics of the light source unit from the first server, and reads information (sensitivity data) regarding the characteristics of the optical device (more specifically, the characteristics of the optical unit) from the second server, and TIΦ data is created within the optical device.

[0028] The first server may be, for example, a server managed by a light source manufacturer, and the second server may be, for example, a server managed by an apparatus manufacturer.

[0029] the optical output control system includes a first server having the first storage unit; the second storage unit, the data creation unit, and the coefficient determination unit are mounted within the optical device, The data creation unit may create the TIΦ data based on the TIS data downloaded from the first storage unit of the first server and the sensitivity data read from the second storage unit.

[0030] According to this configuration, the optical device reads information (TIS data) regarding the characteristics of the light source unit from the first server, and reads information (sensitivity data) regarding the characteristics of the optical device from a second memory unit installed in the optical device, and TIΦ data is created within the optical device.

[0031] In this configuration, the second storage unit may be a storage area provided within the optical device, or may be a storage medium attached to the optical device.

[0032] the first storage unit is mounted on the optical device in a state where it is attached to the light source unit, the second storage unit, the data creation unit, and the coefficient determination unit are mounted within the optical device, The data creation unit may create the TIΦ data based on the TIS data read from the first storage unit and the sensitivity data read from the second storage unit.

[0033] The optical output control system includes: The optical device; a calculation processing server that is installed at a location separate from the optical device and includes the data creation unit and the coefficient determination unit; A function memory unit mounted in the optical device, the optical device downloads information about the execution control function, which has been determined by the coefficient determination unit in the arithmetic processing server, from the arithmetic processing server and records the information in the function storage unit; The light source control unit may determine the amount of current to be supplied to the light source unit by using the execution control function read from the function storage unit.

[0034] According to this configuration, the creation of TIΦ data and the determination of coefficients are performed in a calculation processing server installed at a location separate from the optical device, and the light source device records information regarding the execution control function determined by the coefficients downloaded from the calculation processing server. Effect of the Invention

[0035] According to the light output control system of the present invention, it is possible to control the light output with excellent accuracy and responsiveness, while reflecting the usage mode of the light source device. [Brief description of the drawings]

[0037] Hereinafter, embodiments of the optical output control system according to the present invention will be described with reference to the drawings.

[0038] The optical output control system is a system for controlling the optical output emitted from an optical device to a desired optical output in accordance with the manner in which the optical device is used.

[0039] [First embodiment] A first embodiment of a light output control system according to the present invention will be described with reference to the drawings as appropriate.

[0040] 1A and 1B are flow charts showing a typical procedure executed by an optical output control system. This procedure is common to the optical output control systems of the second and subsequent embodiments. In the following description, step numbers (e.g., step #1) shown in Figs. 1A and 1B will be referred to as appropriate.

[0041] 1C is a block diagram showing a schematic configuration of an example of the optical output control system of this embodiment. The optical output control system 1 includes an optical device 2, a first server 60, and a second server .

[0042] The optical device 2 includes a light source unit 10 including a solid-state light source, an optical unit 14 that guides the light emitted from the light source unit 10, a current supply unit 12 that supplies current to the light source unit 10, a light source control unit 7 that determines by calculation the amount of current supplied from the current supply unit 12 to the light source unit 10, and a temperature detection unit 13 that detects the environmental temperature T of the light source unit 10. Note that a target light output input unit 41 shown in FIG. 1C will be described later.

[0043] The light source unit 10 includes a substrate on which one or more solid-state light sources are mounted, and a cooling mechanism (not shown). Examples of the cooling mechanism include a heat sink, a fan, a water-cooled panel, and a heat pipe. The solid-state light source mounted in the light source unit 10 is typically an LED, but may be another solid-state light source such as a laser diode element (LD element).

[0044] The optical unit 14 is an intermediate member that guides the emitted light from the light source unit 10 to the irradiation object 19, and is composed of a lens, a filter, etc. The light source unit 10 emits light when a current is supplied from the current supply unit 12, and this light is irradiated to the irradiation object 19 as emitted light L2 via the optical unit 14. The irradiation object 19 is changed depending on the purpose of use of the optical device 2.

[0045] The first server 60 includes a first storage unit M1, and is configured to be able to exchange information with the optical device 2 via an electric communication line 51. The second server 70 includes a second storage unit M2, and is configured to be able to exchange information with the optical device 2 via an electric communication line 52. Note that the electric communication line 51 and the electric communication line 52 may be a common electric communication line or may be different electric communication lines.

[0046] The first storage unit M1 included in the first server 60 stores information (hereinafter, referred to as "TIS data") related to the characteristics of the light source unit 10. The first storage unit M1 may store TIS data for each type α of the light source unit 10.

[0047] The TIS data is data that specifies the relationship between the optical output P1(λ) of the light source unit 10 for each wavelength λ, the environmental temperature T1 of the light source unit 10, and the amount of current I1 supplied to the light source unit 10 for each type α of the light source unit 10. For example, the TIS data may be data related to the emission spectrum S(T1, I1) when the environmental temperature T1 of the light source unit 10 and the amount of current I1 supplied to the light source unit 10 are respectively varied. Also, for example, the TIS data may be a four-dimensional data string that specifies the optical output P1 of the light source unit 10 by the environmental temperature T1 of the light source unit 10, the amount of current I1 supplied to the light source unit 10, and the wavelength λ.

[0048] For example, if the administrator who manages the first server 60 is a light source manufacturer, the environmental temperature T1 of the light source unit 10 and the amount of current I1 supplied to the light source unit 10 can be respectively set for each type α of the light source unit 10 sold by the light source manufacturer before shipping, the emission spectrum of the light source unit 10 can be measured, and the TIS data based on the measurement results can be recorded in the first storage unit M1. However, in the present invention, the administrator of the first server 60 is not limited to the light source manufacturer.

[0049] The second storage unit M2 included in the second server 70 stores information (hereinafter referred to as "sensitivity data") related to the characteristics of the optical device 2. The second storage unit M2 may store sensitivity data for each type β of the optical device 2, for each type γ of the irradiation object 19, or for both the type β of the optical device 2 and the type γ of the irradiation object 19.

[0050] The sensitivity data is data indicating the sensitivity for each wavelength from the time when the light emitted from the light source unit 10 is actually irradiated onto the irradiation object 19. For example, the sensitivity data is one or both of data on the transmittance for each wavelength of the optical unit 14 mounted on the optical device 2 and data on the light sensitivity for each wavelength of the irradiation object 19 to which the optical device 2 is applied.

[0051] For example, if the administrator who manages the second server 70 is the manufacturer of the optical device 2, the administrator can recognize information about the optical unit 14 mounted on the optical device 2 sold by the manufacturer. Therefore, for each type β of the optical device 2, data about the transmittance by wavelength of the optical unit 14 mounted on the optical device 2 can be recorded in the second storage unit M2. Here, if a plurality of optical units 14 are mounted on the optical device 2, the composite data of the transmittance by wavelength may be recorded in the second storage unit M2, or the data of the transmittance by wavelength for each type of optical unit 14 mounted on the optical device 2 may be recorded in the second storage unit M2, and the composite data of the transmittance by wavelength of each optical unit 14 may be derived in the second server 70.

[0052] Furthermore, if the administrator who manages the second server 70 is the manufacturer of the optical device 2, the administrator can also grasp the use of the optical device 2, in other words, the type of the irradiation object 19 to which the light L2 from the optical device 2 is irradiated. Depending on the irradiation object 19, a tendency of wavelength sensitivity may appear for each wavelength of the light L2. In such a case, data on the sensitivity spectrum for each type γ of the irradiation object 19 is recorded in the second storage unit M2.

[0053] That is, the sensitivity data for each optical device 2 recorded in the second storage unit M2 corresponds to information on the light intensity for each wavelength λ that is actually irradiated onto the irradiation target 19, assuming that the light emitted from the light source unit 10 mounted on the optical device 2 is light exhibiting a single intensity. In other words, the sensitivity data for each optical device 2 is information on the spectral transmittance D(λ) of the light source unit 10.

[0054] However, in the present invention, the managing entity of the second server 70 is not limited to the device manufacturer.

[0055] The light output control system 1 includes a data creation unit 3, a coefficient determination unit 4, a function storage unit 5, an execution function storage unit 6, and a light source control unit 7. In the light output control system 1 of this embodiment, the data creation unit 3, the coefficient determination unit 4, the function storage unit 5, the execution function storage unit 6, and the light source control unit 7 are all configured by an arithmetic processing unit 20 mounted in the optical device 2.

[0056] The data creation unit 3, the coefficient determination unit 4, and the light source control unit 7 are functional means for performing arithmetic processing, and are software means or hardware means. The function storage unit 5 and the execution function storage unit 6 are storage areas in which information about functions described later is recorded, and are composed of, for example, a hard disk, a non-volatile memory, etc.

[0057] The data creation unit 3 reads out the TIS data recorded in the first storage unit M1 and the sensitivity data recorded in the second storage unit M2 (steps #1 and #2), corrects the TIS data based on the sensitivity data, and creates corrected TIS data (step #3). Note that the optical device 2 may include a data reading means (not shown), which reads out the TIS data recorded in the first storage unit M1 and the sensitivity data recorded in the second storage unit M2, temporarily records them in a storage unit (not shown), and the data creation unit 3 may read out the TIS data and the sensitivity data from the storage unit and process them.

[0058] As described above, the TIS data recorded in the first memory unit M1 is data that specifies the relationship between the optical output P1(λ) for each wavelength λ of the light source unit 10, the environmental temperature T1 of the light source unit 10, and the amount of current I1 supplied to the light source unit 10 for each type α of the light source unit 10. In other words, this TIS data takes into consideration the characteristics of the light source unit 10 mounted on the optical device 2, but does not take into consideration the characteristics of the optical device 2, more specifically, information related to the transmission spectrum of the optical unit 14 mounted on the optical device 2 and the sensitivity spectrum of the irradiation target 19.

[0059] Therefore, the data creation unit 3 performs a process of correcting the TIS data based on the sensitivity ratio D(λ) defined in the sensitivity data related to the characteristics of the optical device 2 side, which is recorded in the second storage unit M2 (step #3). The data obtained by this process is called "corrected TIS data."

[0060] As a specific example, the corrected TIS data can be obtained by multiplying the optical output P1(λ) for each wavelength λ of the light source unit 10, which is defined by the environmental temperature T1 of the light source unit 10 and the amount of current I1 supplied to the light source unit 10, by the sensitivity ratio D(λ) recorded in the second storage unit M2. According to the corrected TIS data derived by this calculation, the relationship between the optical output P2(λ) for each wavelength λ on the irradiation surface of the irradiation target 19, the environmental temperature T1 of the light source unit 10, and the amount of current I1 supplied to the light source unit 10 is defined.

[0061] Furthermore, based on the obtained corrected TIS data, the data creation unit 3 creates TIΦ data by calculation, which is the relationship between the integrated value Φ of the optical output P2(λ) over a specific wavelength range, the environmental temperature T1 of the light source unit 10, and the amount of current I1 supplied to the light source unit 10 (step #4).

[0062] Since the corrected TIS data is information regarding the optical output P2(λ) for each wavelength λ on the irradiation surface of the object to be irradiated 19, which is determined by the environmental temperature T1 of the light source unit 10 and the amount of current I1 supplied to the light source unit 10, by integrating the optical output P2 over a predetermined wavelength range Λ under the conditions specified by the environmental temperature T1 of the light source unit 10 and the amount of current I1 supplied to the light source unit 10, the integrated value Φ of the optical output under the conditions specified by the environmental temperature T1 of the light source unit 10 and the amount of current I1 supplied to the light source unit 10 is derived.

[0063] Here, the wavelength range Λ to be integrated may be a wavelength range in which the target processing can be performed on the irradiation object 19 by supplying light energy to the irradiation object 19. In other words, it may be a wavelength range with relatively high sensitivity excluding wavelength ranges with extremely low sensitivity in the sensitivity spectrum of the irradiation object 19. In other words, the wavelength range Λ may be set according to the type γ of the irradiation object 19.

[0064] The TIΦ data created by the data creation unit 3 is information indicating the total value Φ of the optical output over a specific wavelength range Λ on the irradiation surface of the irradiation object 19 under conditions defined by the environmental temperature T1 of the light source unit 10 and the amount of current I1 supplied to the light source unit 10. In other words, according to the TIΦ data, when the amount of current I1 supplied to the light source unit 10 mounted on the optical device 2 and the environmental temperature T1 of the light source unit 10 mounted on the optical device 2 are specified, it is possible to specify the value Φ of the optical output acting on the irradiation object 19 when the irradiation object 19 is irradiated with light L2 using the optical device 2.

[0065] The function storage unit 5 stores information on the control function used to determine the amount of current to be supplied to the light source unit 10. As described above, the "control function" is a function whose coefficient values ​​have not been specifically determined, and is a concept that defines the "type" of the function. The control function is, for example, a quadratic function, a trigonometric function, or a binary multi-dimensional linear combination function determined by arbitrary variables and coefficients. Meanwhile, the coefficient determination unit 4 determines the coefficient to be applied to the "control function" by arithmetic processing. The coefficient to be applied to the control function is specified by the coefficient determination unit 4, and thus the function to be actually used for current control for the light source unit 10 is determined. The control function whose coefficients have been determined in this manner is called an "execution control function."

[0066] The coefficient determination unit 4 determines coefficients by fitting the control function recorded in the function storage unit 5 based on the TIΦ data obtained by the data creation unit 3, thereby determining the execution control function (step #5). As a specific example, the coordinate group (x i ,y i ,z i ) (where i=0, 1, ..., n), a control function defined in the following equation (1) is fitted using, for example, the least squares method, where k and j are integers equal to or greater than 1.

[0067] Here, as a specific example, a detailed description will be given of the case where k = 2 and j = 2. In this case, the above formula (1) is specifically defined by the following formula (2).

[0068] The coefficient α to be found tsIf we express it as a vertical vector C, it can be defined by the following equation (3).

number

[0071] In this case, the coefficient α defined by the vertical vector C in equation (3) ts is calculated based on the following formula (6): T is the transpose of matrix (column vector) A, (A T A) -1 is a matrix (A T ·A) is the inverse matrix.

number

[0072] Each element of the matrix C obtained by the above formula (6) has a coefficient α ts (t=0,1,2; s=0,1,2). In other words, the coefficient determination unit 4 performs the calculation defined by the above formula (6) to determine each coefficient α ts Then, this coefficient α tsThe formula obtained by applying the above to formula (2) corresponds to the execution control function. This execution control function is a set of coordinates (x i ,y i ,z i ) (where i=0, 1, . . . , n) by the least squares method, and corresponds to a curved surface function in this embodiment. ts is a factor that determines the shape of the control function.

[0073] The coefficient α determined by the coefficient determination unit 4 in this manner ts is applied to the control function indicating the "type" of the function recorded in the function storage unit 5, and the execution control function is determined (step #5). Information about the determined execution control function is recorded in the execution function storage unit 6.

[0074] In other words, the execution control function recorded in the execution function memory unit 6 is information that specifies the relationship between the environmental temperature T1 of the light source unit 10, the amount of current I1 supplied to the light source unit 10, and the integrated value Φ of the light output irradiated to the irradiation object 19, while reflecting the characteristics of the light source unit 10 mounted on the optical device 2 as well as the characteristics of the optical unit 14 and / or the irradiation object 19 mounted on the optical device 2.

[0075] The temperature detection unit 13 outputs information on the temperature (ambient temperature) T in the vicinity of the installation location of the light source unit 10 including the solid-state light source to the light source control unit 7 at intervals of, for example, several microseconds to several tens of seconds. The temperature detection unit 13 may use a known temperature measurement means such as a radiation thermometer or a thermistor as long as it is configured to be able to detect temperature and output the detected information. The installation location of the temperature detection unit 13 is not limited as long as it can detect the ambient temperature of the light source unit 10. For example, the temperature detection unit 13 may be built into the light source unit 10, or may be installed in the vicinity of the outside of the light source unit 10.

[0076] The target light output input unit 41 is a means for inputting an instruction signal for adjusting the light output of the light source unit 10, and is typically operated by a user. As an example, the target light output input unit 41 is composed of an operation button, a knob, a dial, a scroll bar on a touch panel, an input form, and the like. The target light output input unit 41 may be attached to the housing of the optical device 2, or may be composed of an operation terminal, a smartphone, and the like provided at a position away from the optical device 2. The target light output input unit 41 may also be one that inputs a target value by a program or sequence including information on the irradiation time, light intensity, and lighting interval, and the like. Furthermore, the target value may be input by a separate detection means. As an example, in order to keep the illuminance of the irradiation surface constant, distance information can be measured and a light output value corresponding to the distance can be input as a target value.

[0077] When the user wishes to increase or decrease the current optical output of the light L2, the user operates the target optical output input unit 41 to specify the desired optical output. Information on the desired optical output inputted through the target optical output input unit 41 (information corresponding to the target optical output Φ) is inputted to the light source control unit 7.

[0078] The light source control unit 7 reads out information about the environmental temperature T of the light source unit 10 output from the temperature detection unit 13 and information about the target light output Φ input from the target light output input unit 41 (steps #11 and #12). Then, the light source control unit 7 reads out an execution control function from the execution function storage unit 6 and substitutes the values ​​of the environmental temperature T and the target light output Φ to calculate the amount of current I to be supplied to the light source unit 10 (hereinafter, sometimes referred to as "amount of supply current I") (step #13).

[0079] For example, in the control function defined by the above equation (2), each coefficient α tsInformation on the control function in a state where the values ​​of (t=0,1,2; s=0,1,2) are determined, i.e., information on the execution control function, is recorded in the execution function storage unit 6. The light source control unit 7 converts the information on the target light output Φ input from the target light output input unit 41 into the information on the target light output Φ defined by the formula (2) and each coefficient α ts After the value of z is determined, a calculation is performed by substituting the variable x of the execution control function and the environmental temperature T of the light source unit 10 input from the temperature detection unit 13 into the variable y of the same function, and the obtained value of z is used as the amount of supply current I.

[0080] The current supply unit 12 supplies the current of the current amount I calculated by the light source control unit 7 to the light source unit 10 (step #14). The current supply unit 12 is a circuit that can vary the amount of current, and is connected to a power source (not shown).

[0081] The light source control unit 7 repeats the above steps #13 to #14 until an end instruction is received (No in step #15). More specifically, if the information on the target light output Φ has not been changed via the target light output input unit 41 (No in step #16), the light source control unit 7 reads out information on the environmental temperature T from the temperature detection unit 13 and performs calculation processing corresponding to steps #13 to #14 to calculate the amount of supply current I. The current supply unit 12 adjusts the amount of supply current I to the light source unit 10 every time the information on the amount of supply current I is updated by the light source control unit 7.

[0082] Furthermore, when information on the target light output Φ is changed via the target light output input unit 41 (Yes in step #15), the light source control unit 7 reads information on the environmental temperature T from the temperature detection unit 13, and also reads information on the newly input target light output Φ from the target light output input unit 41 (steps #11, #12), and performs calculations corresponding to steps #13 to #14 to calculate the amount of supply current I. The current supply unit 12 adjusts the amount of supply current I to the light source unit 10 every time the information on the amount of supply current I is updated from the light source control unit 7.

[0083] When an instruction to end the irradiation of light L2 is given to the optical device 2 (Yes in step #15), the control of the light output control system 1 is ended.

[0084] As described above, according to the light output control system 1 of the present embodiment, feedforward control is performed based on an executive control function that reflects the characteristics (light source side characteristics) of the light source unit 10 mounted on the optical device 2 and the characteristics (light source user side characteristics) of the optical unit 14 and / or the irradiation object 19 arranged downstream of the light source unit 10. According to this type of control, it is possible to obtain an optical output close to the optical output Φ that is actually desired to be irradiated onto the irradiation object 19. Furthermore, the calculation required when actually controlling the optical output is simply a process of substituting the environmental temperature T and the target optical output Φ into the executive control function to calculate the supply current amount I, so the amount of calculation is extremely small, and fast responsiveness is achieved.

[0085] In the light output control system 1 of this embodiment, the data creation unit 3 creates corrected TIS data based on the TIS data recorded in the first storage unit M1 in the first server 60 and the sensitivity data recorded in the second storage unit M2 in the second server 70. In this case, the optical device 2 may access the first server 60 through the electric communication line 51 and download the TIS data corresponding to the type α of the light source unit 10 mounted in the optical device 2. Similarly, the optical device 2 may access the second server 70 through the electric communication line 52 and download the sensitivity data corresponding to the type β of the optical device 2 and / or the type γ of the irradiation target 19.

[0086] As a detailed example, when the optical device 2 accesses the first server 60, information on the type β of the optical device 2 or identification information unique to the device may be transmitted to the first server 60, and the first server 60 may identify the type α of the corresponding light source unit 10 and transmit TIS data corresponding to the type α of the light source unit 10 to the optical device 2. Similarly, when the optical device 2 accesses the second server 70, information on the type β of the optical device 2 or identification information unique to the device may be transmitted to the second server 70, and the second server 70 may transmit sensitivity data corresponding to the type β of the corresponding optical device 2 to the optical device 2. Furthermore, information corresponding to the type γ of the irradiation object 19 may be transmitted from the optical device 2 to the second server 70, and the second server 70 may transmit sensitivity data corresponding to the type γ of the corresponding irradiation object 19 to the optical device 2.

[0087] [Second embodiment] A second embodiment of the optical output control system according to the present invention will be described, focusing mainly on the differences from the first embodiment. In the following embodiments, elements common to the first embodiment are given the same reference numerals, and the description thereof will be appropriately simplified or omitted. The optical output control systems of the following embodiments are also common to the first embodiment in that the processes shown in Figures 1A and 1B are executed.

[0088] Fig. 2 is a block diagram showing a schematic example of the configuration of the light output control system 1 of this embodiment. As shown in Fig. 2, the light output control system 1 of this embodiment is different from the first embodiment in that a second storage unit M2 in which sensitivity data is recorded is installed in the optical device 2.

[0089] As described above in the first embodiment, the second storage unit M2 records sensitivity data reflecting the characteristics of the optical device 2. For this reason, for example, an equipment manufacturer can mount in the optical device 2 a second storage unit M2 in which data relating to the characteristics of the optical device 2, more specifically, the transmittance by wavelength of the optical unit 14 mounted in the optical device 2, is recorded in advance.

[0090] In addition, when the purpose of use of the optical device 2 is limited, data regarding the optical sensitivity by wavelength of the irradiation object 19 to which L2 is actually irradiated using the optical device 2 can also be recorded in advance in the second memory unit M2 within the optical device 2.

[0091] In the case of the light output control system 1 of this embodiment, the optical device 2 accesses the first server 60 and downloads TIS data corresponding to each type α of the light source unit 10. Then, the data creation unit 3 creates corrected TIS data based on the TIS data downloaded from the first server 60 and the sensitivity data related to the optical device 2 read from the second storage unit M2 included in the optical device 2 (step #3). Then, the data creation unit 3 creates TIΦ data based on the obtained corrected TIS data in the same manner as in the first embodiment (step #4). The process of determining a coefficient for identifying an execution control function, which is performed by the coefficient determination unit 4 (step #5), is the same as in the first embodiment.

[0092] According to the optical output control system 1 of this embodiment, it is not necessary to make the optical device 2 access the second server 70 managed by, for example, an equipment manufacturer. Therefore, the user of the optical device 2 will not access information managed by the equipment manufacturer, and the equipment manufacturer of the optical device 2 can easily propose the use of the optical output control system 1 to the user of the optical device 2.

[0093] In this embodiment, the second storage unit M2 may be an external storage medium that can be attached to the optical device 2, such as a memory card.

[0094] [Third embodiment] A third embodiment of the optical output control system according to the present invention will be described, focusing mainly on the differences from the first embodiment.

[0095] Fig. 3 is a block diagram showing a schematic example of the configuration of the light output control system 1 of this embodiment. As shown in Fig. 3, the light output control system 1 of this embodiment is different from the second embodiment in that a first storage unit M1 in which TIS data corresponding to the light source unit 10 is recorded is installed in the optical device 2.

[0096] As described above in the first embodiment, the first storage unit M1 records TIS data that defines the relationship between the optical output P1(λ) for each wavelength λ of the light source unit 10, the environmental temperature T1 of the light source unit 10, and the amount of current I1 supplied to the light source unit 10. For this reason, it is possible for a light source manufacturer to attach to the light source unit 10 a first storage unit M1 in which TIS data related to the light source unit 10 is recorded in advance.

[0097] In the case of the light output control system 1 of this embodiment, the optical device 2 reads out TIS data from a first storage unit M1 attached to the light source unit 10, in other words, mounted in the optical device 2, and further reads out sensitivity data from a second storage unit M2 mounted in the optical device, and the data creation unit 3 creates corrected TIS data based on both data (step #3). Then, the data creation unit 3 creates TIΦ data based on the obtained corrected TIS data in the same way as in the first embodiment (step #4). The process of determining coefficients for identifying the execution control function, which is performed by the coefficient determination unit 4 (step #5), is the same as in the first embodiment.

[0098] That is, the optical output control system 1 of this embodiment can perform stand-alone output control of the light L2 emitted from the optical device 2. Therefore, according to the optical output control system 1 of this embodiment, it is not necessary to make the optical device 2 access the first server 60 managed by a light source manufacturer and the second server 70 managed by an equipment manufacturer, for example. Therefore, the user of the optical device 2 will not access information managed by the light source manufacturer or the equipment manufacturer, and it becomes easier for the light source manufacturer and the equipment manufacturer to propose the use of the optical output control system 1 to the user of the optical device 2.

[0099] In this embodiment, the first storage unit M1 and / or the second storage unit M2 may be an external storage medium that can be attached to the optical device 2, such as a memory card.

[0100] [Fourth embodiment] A fourth embodiment of the optical output control system according to the present invention will be described, focusing mainly on the differences from the first embodiment.

[0101] Fig. 4 is a block diagram showing a schematic example of the configuration of the optical output control system 1 of this embodiment. As shown in Fig. 4, the optical output control system 1 of this embodiment is different from the first embodiment in that it includes a calculation processing server 80 arranged outside the optical device 2. The data creation unit 3, the coefficient determination unit 4, and the function storage unit 5 are mounted on the calculation processing server 80, not on the optical device 2.

[0102] As described above, in the light output control system 1 of the first embodiment, the data creation unit 3 mounted in the optical device 2 creates corrected TIS data by arithmetic processing, and the coefficient determination unit 4 mounted in the optical device 2 determines coefficients for identifying an execution control function by arithmetic processing. In contrast, the light output control system 1 of the present embodiment is different in that the arithmetic processing for creating corrected TIS data and the arithmetic processing for determining the coefficients are performed by the arithmetic processing server 80 installed outside the optical device 2. In other words, the processes relating to steps #1 to #5 are performed by the arithmetic processing server 80.

[0103] The arithmetic processing server 80 is configured to be able to exchange information with the first server 60 via the electric communication line 53. The arithmetic processing server 80 is configured to be able to exchange information with the second server 70 via the electric communication line 54. The arithmetic processing server 80 is configured to be able to exchange information with the optical device 2 via the electric communication line 55. Two or more of the electric communication lines 53, 54, and 55 may be a common communication line, or all of the electric communication lines 53, 54, and 55 may be different communication lines.

[0104] When an instruction signal is input from the optical device 2, the arithmetic processing server 80 accesses the first server 60 and downloads from the first storage unit M1 the TIS data corresponding to each type α of the light source unit 10 mounted in the optical device 2. Here, the instruction signal input from the optical device 2 to the arithmetic processing server 80 may include information on the type β of the optical device 2 or identification information unique to the device. In this case, the arithmetic processing server 80 downloads the TIS data corresponding to the type α of the light source unit 10 mounted in the optical device 2 from the first server 60, based on the information on the type β of the optical device 2 or the identification information unique to the device.

[0105] Here, the arithmetic processing server 80 may specify the type α of the light source unit 10 based on information related to the type β of the optical device 2 or identification information unique to the device, and request the first server 60 for TIS data corresponding to the type α of the light source unit 10. In this case, the first server 60 transmits the requested TIS data corresponding to the type α of the light source unit 10 to the arithmetic processing server 80.

[0106] As another example, the arithmetic processing server 80 may transmit information related to the type β of the optical device 2 or device-specific identification information to the first server 60, and the first server 60 may specify the type α of the light source unit 10. In this case, the first server 60 transmits to the arithmetic processing server 80 TIS data corresponding to the type α of the light source unit 10 specified by the first server 60.

[0107] When an instruction signal is input from the optical device 2, the calculation processing server 80 further accesses the second server 70 and downloads sensitivity data corresponding to the type β of the optical device 2 and / or the type γ of the irradiation object 19 from the second memory unit M2.

[0108] The calculation processing server 80 creates corrected TIS data in the data creation section 3 based on the TIS data downloaded from the first server 60 and the sensitivity data downloaded from the second server 70, and also creates TIΦ data based on the corrected TIS data (steps #3 and #4). The methods of creating the corrected TIS data and TIΦ data are similar to the processes described above in the first embodiment.

[0109] Furthermore, the calculation processing server 80 determines coefficients and determines the execution control function by fitting the control function recorded in the function storage unit 5 based on the TIΦ data obtained by the data creation unit 3 in the coefficient determination unit 4 (step #5). The method of determining the coefficients to be applied to the control function is the same as the process of step #5 described above in the first embodiment.

[0110] The arithmetic processing server 80 transmits information about the execution control function that has been determined by the coefficient determination unit 4 to the optical device 2 via the electric communication line 55, and this information is recorded in the execution function storage unit 6. Note that, if information about the control function before the coefficient is determined is recorded on the optical device 2 side, only the information about the coefficient may be transmitted from the arithmetic processing server 80 to the optical device 2, and the optical device 2 may determine the execution control function by applying the determined coefficient to the control function and record it in the execution function storage unit 6.

[0111] The processing contents of the light source control unit 7 are the same as steps #11 to #16 described above in the first embodiment. That is, the light source control unit 7 applies the environmental temperature T of the light source unit 10 input from the temperature detection unit 13 and the target light output Φ input from the target light output input unit 41 to the execution control function recorded in the execution function storage unit 6, thereby calculating the amount of current I to be supplied to the light source unit 10.

[0112] According to the light output control system 1 of this embodiment, the arithmetic processing required to identify the execution control function is performed by the arithmetic processing server 80 outside the optical device 2, so that the optical device 2 does not need to temporarily or continuously store information regarding the characteristics of the light source unit 10 or information regarding the characteristics of the optical device 2. This makes it possible to reduce the possibility that the user of the optical device 2 will access the information regarding the characteristics of the light source unit 10 or information regarding the characteristics of the optical device 2.

[0113] Also, in this embodiment, a second storage unit M2 in which sensitivity data is recorded may be mounted in the optical device 2 as in the second embodiment (see FIG. 5). In this case, sensitivity data reflecting the characteristics of the optical device 2 is uploaded from the optical device 2 to the calculation processing server 80, and the calculation processing server 80 creates corrected TIS data and TIΦ data in the data creation unit 3 based on the TIS data downloaded from the first server 60 and the sensitivity data received from the optical device 2.

[0114] Furthermore, in this embodiment, similarly to the third embodiment, a first storage unit M1 in which TIS data corresponding to the light source unit 10 is recorded, and a second storage unit M2 in which sensitivity data is recorded may be mounted in the optical device 2 (see FIG. 6). In this case, the optical device 2 uploads TIS data reflecting the characteristics of the light source unit 10 and sensitivity data reflecting the characteristics of the optical device 2 to the calculation processing server 80, and the calculation processing server 80 creates corrected TIS data and TIΦ data in the data creation unit 3 based on the TIS data and sensitivity data received from the optical device 2.

[0115] [Another embodiment] Another embodiment will now be described.

[0116] <1> In the light output control system 1 of the second embodiment described above with reference to Fig. 2, the second storage unit M2 is mounted in the optical device 2, but the first storage unit M1 may be mounted in the optical device 2 (see Fig. 7). In this case, the data creation unit 3 mounted in the optical device 2 reads out TIS data from the first storage unit M1 attached to the light source unit 10, in other words, mounted in the optical device 2, reads out sensitivity data from the second server 70, and creates corrected TIS data and TIΦ data based on both data.

[0117] Similarly, in the light output control system 1 of the fourth embodiment described above with reference to Fig. 5, the second storage unit M2 is mounted in the optical device 2, but the first storage unit M1 may be mounted in the optical device 2 (see Fig. 8). In this case, TIS data reflecting the characteristics of the light source unit 10 is uploaded from the optical device 2 to the arithmetic processing server 80. The arithmetic processing server 80 generates corrected TIS data and TIΦ data in the data creation unit 3 based on the TIS data received from the optical device 2 and the sensitivity data downloaded from the second server 70.

[0118] <2> It is assumed that the light source unit 10 will need to be replaced due to factors such as deterioration of the life span of the solid-state light source mounted in the light source unit 10 over time or a malfunction. When the light source unit 10 is replaced, the solid-state light source mounted in the light source unit 10 will be different.

[0119] Therefore, the data creation unit 3 of the light output control system 1 of each of the above embodiments may perform a process of creating corrected TIS data and TIΦ data and update the TIΦ data when the light source unit 10 is replaced. In this case, the coefficient determination unit 4 of the light output control system 1 of each of the embodiments fits a control function to the updated TIΦ data to newly determine the coefficient. The newly determined execution control function is recorded in the execution function storage unit 6. This updates the execution control function used to control the amount of current I supplied to the light source unit 10.

[0120] According to the above configuration, even if the light source unit 10 is replaced, the light output of the optical device 2 can be controlled using an execution control function that takes into account the characteristics of the solid-state light source installed in the new replaced light source unit 10.

[0121] <3> In the fourth embodiment described above, the arithmetic processing server 80 may include a first storage unit M1 in which TIS data relating to the characteristics of the light source unit 10 mounted on the optical device 2 is recorded (see FIG. 9). In this case, the arithmetic processing server 80 also serves as the first server 60 of the light output control system 1 in FIG. 4.

[0122] Similarly, in the fourth embodiment described above, the arithmetic processing server 80 may include a second storage unit M2 in which sensitivity data relating to the characteristics of the optical device 2 is recorded (see FIG. 10). In this case, the arithmetic processing server 80 also serves as the second server 70 of the light output control system 1 in FIG.

[0123] Furthermore, in the above-described fourth embodiment, the arithmetic processing server 80 may include both the first memory unit M1 and the second memory unit M2 (see FIG. 11). In this case, the arithmetic processing server 80 serves as both the first server 60 and the second server 70 of the optical output control system 1 in FIG. 4.

[0124] <4> In the above-described embodiment, one or more of the first server 60, the second server 70, and the calculation processing server 80 may be a cloud server.

[0125] <5> In the fourth embodiment described above with reference to Figs. 4 to 6, the calculation processing server 80 may include only the data creation unit 3, and the coefficient determination unit 4 and the function storage unit 5 may be realized by a server or computer (hereinafter referred to as "another computer") other than the calculation processing server 80. In this case, information on the TIΦ data created by the data creation unit 3 in the calculation processing server 80 is transmitted to the other computer, and in the other computer, the coefficient determination unit 4 performs processing corresponding to step #5 to determine the execution control function. Information on the determined execution control function is transmitted to the optical device 2 and recorded in the execution function storage unit 6. The control based on the execution control function is similar to steps #11 to #16 performed in each embodiment.

[0126] <6> The present invention is not limited to the above-described embodiment, and various modifications are included. That is, the light output control system 1 according to the present invention is not limited to a specific configuration as long as each of the processing procedures described above with reference to Figs. 1A to 1B is executed. For example, the above-described embodiment has been described in detail for a better understanding of the present invention, and is not necessarily limited to a system having all of the configurations described. The scope of the present invention is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. [Explanation of symbols]
