[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] The terms "first" and "second" in this application are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. In the description of this application, "several" and "multiple" mean at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0034] In the related art, the electronic colposcope light source uses a white light source for illumination. If the cervical vascular structure needs to be highlighted, electronic staining is used. However, when using electronic staining technology, the image obtained is processed by the sensor later, not directly reflected by the object to be measured, and the obtained image often has insufficient clarity and brightness and cannot meet the requirements. At the same time, if a filter is added to the white light source, the operation of replacing the filter is complicated and cumbersome due to the need for hardware support, which makes the real-time and stability of the electronic colposcope light source poor. Moreover, the transmitted light after passing through the filter will become darker, so that a higher-power light source is required, which makes the requirements for system power consumption and heat dissipation very high. In addition, frequent replacement of filters in clinical use will cause a decrease in doctor efficiency. At present, the cost of electronically adjustable filters that are electrically adjusted is very high. For cost control, the use of electronically adjustable filters is not advisable.

[0035] In order to solve the above technical problems, a technical solution adopted by the present application is: to provide a light source device, the light source device 10 includes a light source assembly 1 and a control circuit. The light source assembly 1 includes a plurality of white light sources 11 and a plurality of color light sources 12, the color light sources 12 include a blue light source 121, and / or a blue-violet light source 123, and / or a green light source 122; the control circuit is used to control the white light source 11 to emit light and the color light source 12 to turn off, so as to illuminate the object to be tested to obtain an overall image; and is used to control the color light source 12 to work, so as to illuminate the object to be tested to obtain a middle layer and / or surface layer blood vessel image.

[0036] Please combine Figure 1-4 , Figure 1 is a structural schematic diagram of an embodiment of a light source assembly of a light source device provided by the present application, Figure 2 is a structural schematic diagram of another embodiment of a light source assembly of a light source device provided by the present application, Figure 3 is a structural schematic diagram of another embodiment of a light source assembly of a light source device provided by the present application, Figure 4It is a structural schematic diagram of other embodiments of the light source assembly of the light source device provided by the present application.

[0037] Specifically, in one embodiment, the colored light source 12 may include only a blue light source 121, and the white light source 11 may be controlled to emit light while the blue light source 121 is turned off, so as to irradiate the object to be measured to obtain an overall image; the white light source 11 and the blue light source 121 may be controlled to emit light at the same time, so as to irradiate the object to be measured to obtain an image of surface blood vessels; or the white light source 11 may be controlled to be turned off, and the blue light source 121 may be controlled to emit light alone, so as to irradiate the object to be measured to obtain an image of surface blood vessels.

[0038] In another embodiment, the colored light source 12 may include only the green light source 122, and the white light source 11 may be controlled to emit light and the green light source 122 may be turned off, so as to irradiate the object to be tested to obtain an overall image; the white light source 11 and the green light source 122 may be controlled to emit light at the same time, so as to irradiate the object to be tested to obtain an image of the middle-layer blood vessels; or the white light source 11 may be controlled to be turned off, and the green light source 122 may be controlled to emit light alone, so as to irradiate the object to be tested to obtain an image of the middle-layer blood vessels.

[0039] In another embodiment, the colored light source 12 may also include a blue light source 121 and a green light source 122 at the same time, and the white light source 11 is controlled to emit light alone, and the blue light source 121 and the green light source 122 are turned off at the same time, so as to illuminate the object to be measured to obtain an overall image; the white light source 11, the blue light source 121 and the green light source 122 are controlled to emit light at the same time, so as to illuminate the object to be measured to obtain an image of mid-surface blood vessels.

[0040] In another embodiment, the color light source 12 may also include only the blue-violet light source 123, and the blue-violet light source 123 and the blue light source 121 may have the same effect, and can irradiate the object to be tested to obtain a surface blood vessel image. In other embodiments, the color light source 12 may also include the blue light source 121, the green light source 122 and the blue-violet light source 123 (not shown in the figure) at the same time, so as to irradiate the object to be tested to obtain a mid-surface blood vessel image.

[0041] In the embodiment of the present application, the light source device 10 includes a compensation circuit, and the compensation circuit is used to adjust the brightness and / or chromaticity of the white light source 11 and / or the color light source 12.

[0042] Specifically, in one embodiment of the present application, the compensation circuit can adjust the light intensity ratio of the white light source 11 and the color light source 12 according to specific clinical needs and the user's personal habits to achieve a variety of combinations such as light green light source, dark green light source, light blue light source, dark blue light source, light blue-green light source, dark blue-green light source, light blue-purple light source, dark blue-purple light source, and white light source, thereby realizing a multi-spectrum light source to meet the vast majority of clinical use scenarios. In another embodiment of the present application, the compensation circuit can also perform chromaticity compensation on the white light source 11 and the color light source 12 by controlling the current intensity and voltage intensity.

[0043] In one embodiment of the present application, a plurality of white light sources 11 and a plurality of colored light sources 12 are arranged in a ring structure. Specifically, the ring structure can make the white light source 11 and the colored light source 12 surround the lens, reduce the uneven brightness, improve the uniformity of illumination, reduce lens halo, and thus improve image quality. At the same time, the ring structure enables each white light source 11 and the colored light source 12 to orient the lens. By adjusting the angle of each light source, the illumination direction can be flexibly controlled to achieve fill light for the dark part of the subject.

[0044] In another embodiment of the present application, the colored light sources 12 are arranged in a centrally symmetrical manner, which can improve the overall illumination uniformity. That is, when white light is used alone, the colored light source 12 is not lit, thereby reducing the impact of the colored light source 12 on the overall illumination uniformity of the light source.

[0045] Specifically, in one embodiment, the colored light source 12 may include only a blue light source 121, and eight white light sources 11 and four blue light sources 121 are provided, wherein the four blue light sources 121 are centrally symmetrically arranged, and the white light sources 11 and the blue light sources 121 are arranged in a ring structure, so that the light emitted by the light source is more uniform, thereby improving the uniformity of the illumination, thereby enabling the blue light source 121 to illuminate the object to be measured to obtain a surface blood vessel image.

[0046] In another embodiment, the colored light source 12 may also include only a green light source 122. Eight white light sources 11 and four green light sources 122 are arranged in a ring structure. The four green light sources 122 are symmetrically arranged in pairs and are respectively distributed at the six o'clock, twelve o'clock, three o'clock and nine o'clock directions, so that the green light source 122 can illuminate the object to be measured to obtain a middle-layer blood vessel image.

[0047] In another embodiment, the colored light source 12 may also include only a blue-violet light source 123, and a plurality of white light sources 11 and a plurality of blue-violet light sources 123 are arranged in a ring structure, and the blue-violet light sources 123 are centrally symmetrically arranged to enable the blue-violet light sources 123 to illuminate the object to be measured to obtain a surface blood vessel image.

[0048] In another embodiment, the color light source 12 may also include a blue light source 121 and a green light source 122 at the same time, and eight white light sources 11, two blue light sources 121 and two green light sources 122 are provided. These twelve light sources are arranged in a ring structure, wherein the two blue light sources 121 are arranged in a central symmetric manner and are respectively located at the nine o'clock and three o'clock directions of the ring structure, and the two green light sources 122 are also arranged in a central symmetric manner and are respectively located at the six o'clock and twelve o'clock directions of the ring structure. This arrangement of light sources forms a multi-spectral light source, thereby improving the contrast and authenticity of the acquired image. It may also be arranged so that two blue-violet light sources are located at the six o'clock and twelve o'clock directions, and two green light sources are located at the nine o'clock and three o'clock directions. Among them, the color light source 12 may also include a blue-violet light source 123 and a green light source 122 at the same time, and a similar arrangement structure as described above can achieve the same effect, thereby improving the contrast and authenticity of the acquired image.

[0049] In other embodiments, the colored light source 12 may also include a blue light source 121, a green light source 122 and a blue-violet light source 123 at the same time, and six white light sources 11, two blue light sources 121, two blue-violet light sources 123 and two green light sources 122 are provided. These twelve light sources are arranged in a ring structure, wherein the two blue light sources 121, the two green light sources 122 and the two blue-violet light sources 123 are arranged symmetrically in the center, respectively. This arrangement of light sources forms a multi-spectral light source, so that only a few sets of parameters need to be preset to switch the light emission mode of the light source assembly 1 in real time, without the need to set an additional filter, thereby reducing the production cost of the light source assembly 1, and the light emission mode can be flexibly adjusted. The light intensity ratio of the white light source 11 and the colored light source 12 can be adjusted according to specific clinical needs and the user's personal habits, to achieve a variety of combinations such as light green light source, dark green light source, light blue light source, dark blue light source, light blue-green light source, dark blue-green light source, light blue-violet light source, dark blue-violet light source, white light source, etc., thereby improving the contrast and authenticity of the acquired image and meeting the vast majority of clinical usage scenarios.

[0050] In one embodiment of the present application, the light source assembly 1 further includes a circuit board 13, and the white light source 11 and the color light source 12 are both disposed on the circuit board 13. In another embodiment of the present application, the light source assembly 1 further includes a connector 14, which is disposed on the circuit board 13 and is used to interconnect with a power source, thereby providing power to the light source device 10, so that the light source device 10 can radiate light.

[0051] In the related art, the lens uses a discrete lens. During installation, the lenses need to be installed one by one into the front shell, and then fixed with an additional fixing device, such as a sponge pad. This causes inconvenience in installation and reduces the light intensity of the entire light source due to an extra layer of sponge pad between the light emitting device (usually the light source lamp bead) and the lens, thereby affecting the luminous efficiency.

[0052] To solve related technical problems, please refer to Figure 5 , Figure 5 1 is a schematic diagram of the structure of an embodiment of a lens assembly of a light source device provided in the present application. In the embodiment of the present application, the light source device 10 further includes a lens assembly 2, the lens assembly 2 includes a plurality of lenses 21, the plurality of lenses 21 are connected as a whole, the lens assembly 2 is arranged on one side of the light source assembly 1, and the lenses 21 are used to dim the white light source 11 and the color light source 12.

[0053] Specifically, in one embodiment of the present application, several lenses 21 are connected as one, which reduces the impact of individual differences of the lenses 21 on the uniformity of light, simplifies the installation steps of the lens assembly 2, and reduces the gap between the lens 21 and the white light source 11 and the color light source 12, thereby improving the luminous efficiency and light intensity.

[0054] Furthermore, the lens assembly 2 is arranged on one side of the light source assembly 1, and the plurality of white light sources 11 and the plurality of color light sources 12 correspond to the lens 21 one by one, thereby improving the uniformity of illumination. In one embodiment, the white light source 11 and the color light source 12 may be light emitting diodes. In another embodiment, the light source assembly 1 may also use a laser diode, an organic light emitting diode, a light emitting polymer, or an equivalent solid micro light emitting device.

[0055] In one embodiment of the present application, the lens assembly 2 may include a connecting portion 22, which is located between adjacent lenses 21 and is used to connect a plurality of lenses 21 into one. Specifically, the connecting portion 22 is provided between the lenses 21 to connect a plurality of discrete lenses 21 into a whole, so that when the lens assembly 2 is manufactured, all lenses 21 can be completed through a one-step mold manufacturing process, simplifying the manufacturing process, and installing a plurality of lenses 21 as a whole into the light source device 10, simplifying and facilitating the manufacture and installation of the lens assembly 2.

[0056] In another embodiment, the lens assembly 2 may not be provided with the connecting portion 22, and the lenses 21 may be directly connected to each other, thereby simplifying the process and facilitating installation.

[0057] In another embodiment of the present application, the lens 21 includes a lens body 211 and a lens hole 212; the lens body 211 includes a focusing surface; the lens hole 212 is arranged on the lens body 211, so that the white light source 11 and the color light source 12 pass through the lens hole 212 and are located on one side of the focusing surface, and the focusing surface makes the distribution of light emitted by the lens 21 more uniform, thereby enhancing the regulating effect of the lens 21 on the light emitted by the white light source 11 and the color light source 12, thereby improving the uniformity of the light distribution.

[0058] Furthermore, a focusing curved surface is provided at the bottom of the lens hole 212 for focusing and adjusting part of the light emitted by the white light source 11 and the color light source 12, and the outer side surface of the lens body 211 close to the light source assembly 1 is a total reflection surface for totally reflecting part of the light emitted by the light emitting device to emit parallel light. The focus of the total reflection surface coincides with the focus of the focusing curved surface, which improves the uniformity of the light emitted through the lens 21, and controls the emitted light to diverge within a suitable angle range, so that it only irradiates the area to be inspected, reduces excessive irradiation of the object to be tested, and thus improves or avoids image quality problems caused by reflection or refraction of the object to be tested.

[0059] In another embodiment of the present application, the light source assembly 1 is bonded to the lens assembly 2, and no sponge pad and / or silicone pad adhesive is provided between the light source assembly 1 and the lens assembly 2. Specifically, the light source assembly 1 and the lens assembly 2 are directly bonded to minimize the gap between the white light source 11, the color light source 12 and the lens 21, reduce the loss of light being blocked or absorbed at the contact point between the two, improve the optical transmission efficiency between the white light source 11, the color light source 12 and the lens 21, and thus improve the lighting performance of the light source device 10.

[0060] See also Figure 6 , Figure 6 1 is an exploded structural diagram of an embodiment of a light source device provided by the present application. In the embodiment of the present application, the light source device 10 further includes a housing 3 and a heat sink 4. The housing 3 is used to accommodate the lens assembly 2 and the light source assembly 1; the heat sink 4 is arranged on the side of the light source assembly 1 away from the lens assembly 2.

[0061] Specifically, the housing 3 is used to accommodate the lens assembly 2 and the light source assembly 1, thereby playing a protective role and reducing the damage to the lens assembly 2 and the light source assembly 1 caused by mechanical collision. The heat sink 4 is arranged on the side of the light source assembly 1 away from the lens assembly 2. When the light source assembly 1 is working, heat is generated. If too much heat is accumulated, it will cause the light source assembly 1 to deteriorate and be damaged. The independent heat sink 4 can play a heat dissipation role, and quickly conduct the heat generated by the light source assembly 1 to reduce the temperature of the light source assembly 1 itself, thereby improving the phenomenon that the light source assembly 1 fails due to long-term high-temperature operation.

[0062] Furthermore, in one embodiment, the light source assembly 1, the lens assembly 2, the heat sink 4 and the housing 3 can be connected and fixed by a fixing device to improve the overall stability of the light source device 10, while improving the accuracy and uniformity of light irradiation. In another embodiment, the internal structures of the light source device 10 can also be installed and fixed in coordination with each other, simplifying the installation steps and facilitating installation and disassembly.

[0063] Another embodiment of the present application also includes a second technical solution, which provides an electronic colposcope, including an image acquisition device and the above-mentioned light source device 10, and the image acquisition device is used to acquire the image of the object to be tested when the light source device 10 is started.

[0064] Specifically, in an embodiment of the present application, the image acquisition device may be a camera device. After the light source device 10 is started, the camera device acquires an image of the object to be measured through the illumination provided by the light source device 10, thereby performing the next operation.

[0065] See also Figure 7 , Figure 7 1 is a schematic diagram of the overall structure of an embodiment of a light source device provided by the present application. In the embodiment of the present application, the light source assembly 1 is located around the image acquisition device 5. Specifically, the light source assembly 1 surrounds the image acquisition device 5, which can improve the uniformity of light distribution, so that the doctor or user can clearly observe the results.

[0066] See also Figure 8 , Figure 8 The figure is a schematic diagram of the steps of an embodiment of the electronic colposcope detection method provided by the present application. In the embodiment of the present application, a third technical solution is also included, providing an electronic colposcope detection method including:

[0070] If the doctor cannot make a correct judgment on the obtained white light image, or if the doctor finds a lesion and needs further observation, the multi-spectral light source can be switched, that is, the green light source 122 or the blue light source 121 in the light source is turned on.

[0071] In one embodiment, the green light source 122 or the blue light source 121 can be lit alone, and the driving current or driving voltage of the light source assembly 1 can be adjusted by the compensation circuit to change the light intensity of the light source, so that images with different degrees of colorization, such as light green, dark green images, or light blue, dark blue images, can be obtained. The degree of colorization of the image can be determined according to the light intensity.

[0072] In another embodiment, the green light source 122 and the white light source 11 may be simultaneously lit to obtain light green or dark green images, or the blue light source 121 and the white light source 11 may be simultaneously lit to obtain light blue or dark blue images, thereby compensating for insufficient light intensity caused by lighting the green light source 122 or the blue light source 121 alone.

[0073] In another embodiment, by changing the light intensity ratio of the white light source 11 and the blue or green light source 122, images with different degrees of coloring, such as light green or dark green images with higher light intensity, or light blue or dark blue images, can be obtained. The blue and green light sources 122 can also be lit at the same time to obtain images with different degrees of coloring, such as blue-green, light blue-green, and dark blue-green.

[0074] In other embodiments, the blue, green and white light sources 11 can be lit at the same time to obtain images with different degrees of dyeing such as blue-green, light blue-green, dark blue-green, etc. with higher light intensity. They can also be flexibly adjusted and preset according to the habits of doctors or users to improve the overall lighting uniformity and meet the vast majority of clinical usage scenarios.

In another embodiment of the present application, the intensity ratio of the white, green, and blue light sources needs to be adjusted, and adjusting the light source parameters to match the environment of the object to be measured includes:

[0079] S210, obtaining an initial image of the object to be measured reflecting the light source of the object to be measured based on a preset light intensity;

[0080] After the light source device 10 is turned on, the control circuit controls the white light source 11 to emit light alone, and at the same time the system initializes parameters, and illuminates the object to be measured through the light source device 10, so that the image acquisition device 5 obtains the overall image of the object to be measured.

[0081] S220, converting the initial image into an image signal to obtain an initial brightness value and an initial chromaticity value of the image signal;

[0082] The image acquisition module converts the overall image into an image signal through analog-to-digital conversion, and then separates the brightness value and chromaticity value to obtain the current brightness value and chromaticity value, which are the initial brightness value and initial chromaticity value of the image signal.

[0083] S230 , based on the comparison result between the initial brightness value and the preset brightness value, and the comparison result between the initial chromaticity value and the preset chromaticity value, performing brightness and chromaticity compensation on the light source of the object to be measured.

[0084] The system is preset with brightness value and chromaticity value, and the preset brightness value and chromaticity value are used as a reference to judge whether the brightness and chromaticity of the image are normal. When the initial brightness value is lower or higher than the preset value, the brightness of the white light source 11 can be controlled by the compensation circuit to compensate for the light source of the object to be measured, or the current intensity or voltage intensity can be controlled to compensate. When the initial chromaticity value is lower or higher than the preset value, such as light green or dark green, the current intensity and voltage intensity can be controlled by the compensation circuit to compensate for the light source of the object to be measured. When compensating for the light source of the object to be measured, the white light source 11 is compensated first, and then the colored light source 12 is compensated.
