Description

Technical Field

[0001] This application belongs to the field of laser equipment, and in particular relates to a laser equipment control method and related equipment. Background Technology

[0002] Laser light source devices are used in laser display and lighting applications. The laser tubes in these devices generate heat during operation, and lasers are highly sensitive to temperature. Temperature fluctuations cause fluctuations in the laser's output power, resulting in changes in the color and brightness of the displayed or illuminated area. Therefore, to maintain a relatively constant temperature, cooling components are typically needed to regulate the internal temperature of the laser.

[0003] Because the cooling components, while regulating the temperature of the laser, also affect the temperature of the entire operating environment inside the semiconductor laser device, a decrease in temperature will correspondingly reduce the saturated water vapor content. If the temperature drop is too large, condensation of water vapor in the working environment can occur. Condensation can pose a potential hazard to electrical equipment.

[0004] Existing solutions use dehumidifiers to reduce ambient humidity, thereby keeping the internal temperature of the equipment low and preventing condensation. However, for applications such as movie screenings, the space requiring dehumidification is often large, and using dehumidifiers incurs significant costs. Summary of the Invention

[0052] This application provides a laser equipment control method to solve the problem of condensation that occurs in existing laser equipment during use.

[0053] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application are clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0054] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0055] During the operation of the light source equipment, the laser components generate heat. To ensure the normal operation of the equipment, a cooling component is configured to cool the laser. The operation of the cooling component will lower the temperature of the entire working environment inside the light source equipment. As the temperature decreases, the saturated water vapor content in the environment will also decrease. When the humidity inside the light source equipment is the same as the ambient humidity, the operation of the cooling component may cause condensation of gaseous water inside the light source equipment. When condensation occurs, it may cause damage to the internal circuit boards by the condensed water droplets.

[0056] To address the aforementioned problems, this application provides a laser device control method. Please refer to [link / reference]. Figure 1 One embodiment of the laser device control method of this application includes steps 101-105.

[0057] 101. Get the current temperature.

[0058] The current temperature is obtained from the temperature sensor, which is located inside the laser device to monitor the internal temperature. In the actual implementation of this solution, the current temperature acquisition step can be performed in real time or cyclically at certain time intervals to promptly detect changes in the internal temperature of the laser device.

[0059] 102. Determine the relationship between the difference between the current temperature and the ambient temperature and the preset temperature difference.

[0060] The relationship between the difference between the current temperature and the ambient temperature and the preset temperature difference is determined. The ambient temperature refers to the temperature of the environment in which the laser equipment is located. The ambient temperature can be obtained from a temperature sensor located outside the laser equipment or set manually. When the laser equipment is not operating, the current temperature equals the ambient temperature. Therefore, the ambient temperature can be calculated by averaging the current temperature data over a certain period. The specific method of obtaining the ambient temperature can be determined based on the actual situation and is not limited here. The difference between the current temperature and the ambient temperature (hereinafter referred to as the current temperature difference) represents the impact of the cooling module on the internal environment of the laser equipment.

[0061] The saturated water vapor content parameter is highly correlated with temperature; the higher the temperature, the greater the saturated water vapor content. This can be understood as a higher ambient temperature resulting in a greater mass of water that can dissolve in the air. Condensation easily occurs when the temperature drops, as the mass of water that can dissolve in the air decreases. The condensed water droplets can adhere to the inside of the laser equipment, posing a safety hazard. Therefore, it is necessary to monitor the relationship between the current temperature difference and the preset temperature difference in real time. If the current temperature difference is greater than the preset temperature difference, there is a risk of condensation, requiring adjustment, i.e., executing step 103 to send a slow cooling command to the cooling module. If the current temperature difference is less than the preset temperature difference, no action is needed for now, and the process ends.

[0062] Specifically, the preset temperature difference can be determined based on the ambient temperature. For example, a larger preset temperature difference can be set when the ambient temperature is high, and a smaller preset temperature difference can be set when the ambient temperature is low.

[0063] On the other hand, the critical conditions for condensation to occur vary with the temperature and humidity in the environment. Therefore, the preset temperature difference can be adjusted under different temperature and humidity conditions.

[0064] Specifically, the preset temperature difference can be determined based on the ambient temperature and current ambient humidity.

[0065] For example, when the current ambient humidity is high, a smaller preset temperature difference can be set; when the current ambient humidity is low, a larger preset temperature difference can be set.

[0066] Alternatively, when the current ambient humidity is high but the ambient temperature is also high, a larger preset temperature difference can be designed; when the current ambient humidity is low but the ambient temperature is also low, a larger preset temperature difference can be designed.

[0067] 103. Send a slow cooling command to the cooling module.

[0068] A slow cooling command is sent to the cooling module. Specifically, the slow cooling command reduces the power of the cooling module in the laser device, slowing down the rate of temperature decrease inside the light source device. This reduces the temperature difference between the inside of the light source device and the external environment. For example, if the ambient temperature is 20°C, the cooling module will normally cool the internal temperature of the light source device to 5°C, while the preset temperature difference is 8°C. During the gradual operation of the cooling module, steps 101 and 102 will be executed repeatedly. When the internal temperature of the light source device drops to 12°C, the slow cooling command is triggered. This command reduces the power of the cooling module, maintaining the internal temperature of the light source device at 12°C. This ensures that the temperature difference between the inside of the light source device and the external environment is not too large, thus reducing the risk of condensation. It is understood that the specific adjustment range of the slow cooling command to the cooling module can be determined according to the actual situation, and is not limited here. The cooling module can be a circulating water chiller, a thermoelectric cooler, or other cooling equipment used for cooling and maintaining temperature stability. The specific form of the cooling module can be determined according to the actual situation, and is not limited here.

[0069] As can be seen from the above technical solutions, the embodiments of this application have the following advantages: This solution includes: obtaining the current temperature inside the laser device, determining the relationship between the difference between the current temperature and the ambient temperature and a preset temperature difference; if the difference between the current temperature and the ambient temperature is greater than the preset temperature difference, then sending a slow cooling command to the cooling module. This ensures that the temperature drop inside the laser device is not too large, and the temperature difference between the inside of the laser device and the external environment is maintained within a certain range, thereby avoiding condensation.

[0070] based on Figure 1 The provided embodiments are optional. This application also provides more detailed embodiments that are practically applicable; for details, please refer to [link to specific embodiments]. Figure 2 One embodiment of the laser device control method of this application includes steps 201-207.

[0071] 201. Get the current temperature.

[0072] The current temperature is obtained from the temperature sensor, which is located inside the laser device to monitor the internal temperature. In the actual implementation of this solution, the current temperature acquisition step can be performed in real time or cyclically at certain time intervals to promptly detect changes in the internal temperature of the laser device.

[0073] It is understandable that current temperature data can be stored as historical data for later use, such as in the process of determining ambient temperature. The specific use will depend on the actual situation and is not limited here.

[0074] 202. Determine the relationship between the difference between the current temperature and the ambient temperature and the preset temperature difference.

[0075] The process involves determining the relationship between the difference between the current temperature and the ambient temperature and a preset temperature difference. If the current temperature difference is greater than the preset temperature difference, step 203 is executed; otherwise, the process ends. The implementation method of this step is the same as described above. Figure 1 Step 102 in the corresponding embodiment is similar, and will not be described in detail here.

[0076] It is worth noting that the preset temperature difference value corresponds to the current humidity. Specifically, if the current humidity is 90%, it indicates that the current ambient humidity is high, and even a small change in temperature can easily lead to the dew point. In this case, condensation is likely to occur even with a small temperature difference between the laser equipment's internal temperature and the external environment. Therefore, the preset temperature difference corresponding to 90% humidity can be a lower value, such as 3 or 5 degrees Celsius. Conversely, for lower humidity, such as 30%, condensation is less likely to occur even with a larger temperature difference between the laser equipment's internal temperature and the external environment. Therefore, the preset temperature difference corresponding to 30% humidity can be set to 10 or 15 degrees Celsius. The specific setting can be determined based on the actual situation and is not limited here. This approach makes the solution more suitable for practical use and improves its feasibility.

[0077] 203. Send a slow cooling command to the cooling module.

[0078] A slow cooling command is sent to the cooling module. This command reduces the power of the cooling module in the laser device, slowing the rate of temperature decrease within the light source and thus reducing the temperature difference between the inside of the light source and the external environment. This step is similar to the previously mentioned... Figure 1 Step 103 in the corresponding embodiment is similar, and will not be described in detail here.

[0079] 204. Get the current humidity.

[0080] The current humidity can be obtained through a hygrometer installed inside the device. The humidity value is relative humidity, and the specific value can be determined according to the actual situation. No specific limit is set here.

[0081] 205. Determine if the current humidity exceeds the preset range.

[0082] The system determines whether the current humidity exceeds a preset range. This preset range is set to ensure equipment safety; excessively high humidity can lead to condensation. Therefore, further monitoring of the humidity value is necessary. If the humidity exceeds the preset range, step 206 is executed, sending a stop-work command. If the humidity does not exceed the preset value, it indicates that the current environment will not cause condensation, and no further action is required. It is understood that in actual implementation, step 205 can be repeatedly executed to promptly detect humidity changes, thereby minimizing the occurrence of condensation.

[0083] 206. Send a stop operation command.

[0084] If the current humidity exceeds the preset range, it indicates a high probability of condensation. Therefore, the light source equipment should be stopped to avoid any damage.

[0085] 207. Adjust the white balance reference point of the laser tube.

[0086] The white balance reference point of the laser tube in the laser device is adjusted. For the laser device, when a slow cooling command is issued, the laser tube should normally be cooled to 5 degrees Celsius. However, due to the slow cooling command, the laser tube is only cooled to 15 degrees Celsius. At this point, the laser tube is not operating under the predetermined temperature conditions, resulting in a certain white balance shift. Therefore, the white balance reference point of the laser tube needs to be adjusted. Specific white balance reference point adjustment methods include:

[0087] (1) White balance reference point calibration is performed using a sensor device with white balance reference point detection function. A sensor device with white balance reference point detection function can be used to directly detect the current white balance reference point of the light beam emitted by the light source. The method involves using the sensor device to receive the light beam emitted by the light source, and then the processor built into the sensor device calculates the current white balance reference point of the light beam based on the RGB light intensity values ​​detected by the sensor. Generally, the built-in detection device of the sensor device can be a CCD (Charge-coupled Device) or a CMOS (Complementary Metal-Oxide-Semiconductor).

[0088] (2) White balance reference point correction is performed based on the correspondence table between color temperature and white balance reference point. In some optimization measures, the correspondence table between color temperature and white balance reference point is stored in advance. Then, the color temperature corresponding to the current RGB laser light intensity ratio is detected by the light intensity sensor. Then, the corresponding white balance reference point is found in the correspondence table between color temperature and white balance reference point based on the color temperature.

[0089] (3) White balance reference point correction is performed based on the difference between the laser wavelength of each RGB color and the preset wavelength. In some cases, the difference between the laser wavelength of each RGB color and the preset laser wavelength can be calculated, and then the corrected white balance reference point can be calculated based on this difference. Then, based on the calculated white balance reference point and the number of laser tubes of each color, the correction that can be made for each laser tube is calculated. When there are many laser tubes, the adjustment required for a single laser tube is relatively small.

[0090] It is understandable that the white balance reference point calibration method selected in the actual implementation process can be determined according to the actual situation, and no specific limit is made here. There is no logical relationship in terms of timing between the white balance reference point adjustment process and the humidity-based control process. The specific execution order can be determined according to the user settings, or they can be executed simultaneously, and no specific limit is made here.

[0091] As can be seen from the above technical solutions, the embodiments of this application have the following advantages: This solution includes: acquiring the current temperature inside the laser device, determining the relationship between the difference between the current temperature and the ambient temperature and a preset temperature difference; if the difference between the current temperature and the ambient temperature is greater than the preset temperature difference, a slow cooling command is sent to the cooling module. This reduces the power of the cooling module, ensuring that the temperature difference between the inside of the laser device and the external environment is not too large, thereby avoiding condensation. Simultaneously, humidity information is monitored to minimize the occurrence of condensation. Furthermore, adjusting the white balance reference point of the laser device ensures its performance and improves the feasibility of this solution.
