Description

Technical Field

[0001] This invention belongs to the field of laser lamp technology, and particularly relates to a control system and method for internal humidity of a laser lamp, as well as a high-power RGB laser lamp. Background Technology

[0002] High-power RGB laser lights are widely used in outdoor cultural and tourism lighting, stage lighting, landmark laser shows, and other scenarios. To adapt to complex outdoor environments, laser lights typically need to achieve a high level of waterproof and dustproof protection. Currently, high-power RGB 850W laser lights usually adopt an IP66 waterproof rating design to achieve full-sealed protection.

[0003] In high-power RGB laser lights, the red laser source has extremely strict requirements for operating temperature, which needs to be precisely controlled within the range of 30℃ to 35℃. To this end, existing technologies typically use a TEC (Thermoelectric Cooler) to actively control the temperature of the laser source—activating TEC cooling when the temperature exceeds 35℃ and TEC heating when the temperature falls below 30℃, in order to maintain the laser source within its optimal operating temperature range.

[0004] However, existing technologies have the following problems: First, the fully sealed lamp body has a deficiency in terms of internal air pressure balance. Traditional solutions usually install a waterproof vent valve on the fully sealed lamp body to balance the internal and external air pressure. However, the vent valve is at risk of aging of the vent membrane and a decrease in waterproof performance during long-term use. In addition, it may draw in moisture through the vent membrane in high humidity environments, leading to condensation inside.

[0005] Secondly, the TEC (Transmission Controlled Refrigerant) system is highly susceptible to condensation in high-temperature and high-humidity environments. When the ambient temperature exceeds 35°C and the relative humidity is greater than 75%, after the laser light source emits a bubble-start (activation) signal, the TEC first activates cooling. This rapid cooling causes moisture in the air to condense inside the laser light source, forming condensation. Mild condensation can reduce the luminous efficiency of the laser light source, and severe condensation can cause short circuits or even burn out the light source. Although existing technologies employ dehumidifiers for internal dehumidification, dehumidifiers are complex in structure, expensive, and cannot solve the problem of localized condensation caused by the instantaneous cooling of the TEC.

[0006] Third, existing humidity control strategies lack tiered early warning and linkage protection mechanisms, making it impossible to proactively protect laser light sources under extreme humidity conditions. Summary of the Invention

[0007] This invention provides a control system for the internal humidity of a laser lamp, aiming to solve technical problems in existing high-power RGB laser lamps, such as defects in the internal air pressure balance of the fully sealed lamp body, the condensation problem caused by TEC in high temperature and high humidity environments, and the lack of graded early warning and linkage protection mechanisms in the humidity control strategy.

Wherein, the first humidity threshold is greater than the second humidity threshold, the second humidity threshold is less than or equal to the minimum value of the buffer humidity range, and the extreme humidity threshold is greater than or equal to the maximum value of the buffer humidity range.

[0010] In one embodiment, the humidity control unit includes: A humidity sensor, installed within the fully sealed lamp body and electrically connected to the controller, is used to collect real-time humidity data of the internal space of the fully sealed lamp body; and The heating module, which is installed in the fully sealed lamp body and electrically connected to the controller, is used to heat the internal space or stop heating. The controller is used for: Receive the real-time humidity and obtain the pre-stored first humidity threshold and second humidity threshold; Compare the real-time humidity with the first humidity threshold and the second humidity threshold; When the real-time humidity is greater than the first humidity threshold, the heating module is activated to heat the internal space until the real-time humidity drops to less than or equal to the second humidity threshold; and When the real-time humidity is less than or equal to the second humidity threshold, if the heating module has been activated, it shall be turned off; if the heating module has not been activated, it shall remain turned off.

[0011] In one embodiment, the controller includes an integrated temperature control module, a humidity control module, an alarm control module, and a light source control module. The temperature control module is electrically connected to the light source temperature control unit, the humidity control module is electrically connected to the humidity control unit, the alarm control module is electrically connected to the humidity warning unit, and the light source control module is electrically connected to the laser light source.

[0012] In one embodiment, the heating module is a diode with a heat sink.

[0013] In one embodiment, the volume of the elastic airbag is 3% to 20% of the volume of the internal space.

[0014] This invention also provides a method for controlling the internal humidity of a laser lamp, applied to the control system for the internal humidity of a laser lamp as described in any of the above embodiments. The method for controlling the internal humidity of a laser lamp includes: The light source temperature control unit is controlled to collect the real-time light source temperature of the laser light source, obtain the pre-stored first temperature threshold and second temperature threshold, and compare the real-time light source temperature with the first temperature threshold and the second temperature threshold. When the real-time light source temperature is greater than the first temperature threshold, the light source temperature control unit is controlled to cool down the laser light source until the real-time light source temperature drops to the normal temperature range. When the real-time light source temperature is less than the second temperature threshold, the light source temperature control unit is controlled to heat up the laser light source until the real-time light source temperature rises to the normal temperature range. The humidity control unit collects the real-time humidity of the internal space of the fully sealed lamp body, obtains a pre-stored first humidity threshold, a second humidity threshold, a buffer humidity range, and a limit humidity threshold, and compares the real-time humidity with the first humidity threshold, the second humidity threshold, the buffer humidity range, and the limit humidity threshold.

When the real-time humidity is less than or equal to the second humidity threshold, the humidity control unit is deactivated if it is already activated, and remains deactivated if it is not activated. When the real-time humidity is within the buffer humidity range, the humidity control unit is controlled to be in standby mode. When the real-time humidity is greater than the limit humidity threshold and the laser light source is turned off, the humidity warning unit is controlled to issue an alarm and keep the laser light source off. When the real-time humidity is greater than the limit humidity threshold and the laser light source is turned on, the humidity warning unit is controlled to issue an alarm and turn off the laser light source. When the real-time humidity is less than the first humidity threshold, the alarm of the humidity warning unit is deactivated and the laser light source is turned on.

[0015] This invention also provides a high-power RGB laser light, comprising: Base; A fully sealed lamp body rotatably mounted on the base, wherein a laser light source is disposed within the fully sealed lamp body; and The control system for the internal humidity of the laser lamp as described in any of the above claims is disposed in the fully sealed lamp body and on the fully sealed lamp body.

[0016] In one embodiment, the high-power RGB laser light further includes: The U-shaped support arm includes a bottom support arm rotatably mounted on the base and two side support arms located at both ends of the bottom support arm. The fully sealed lamp body is rotatably mounted between the two side support arms. The air pressure balance unit is located on one side of the fully sealed lamp body and is situated in one of the side support arms.

[0017] In one embodiment, another of the side support arms is provided with a connecting pipe that connects the fully sealed lamp body to the base.

[0018] The humidity control system inside the laser lamp according to embodiments of the present invention has the following beneficial effects: 1. Effectively prevents condensation: By controlling the temperature control unit to preheat the internal space of the fully sealed lamp body when the real-time humidity is greater than the first humidity threshold, the humidity of the internal space is actively reduced before cooling, which fundamentally eliminates the conditions for condensation and avoids the problem of water vapor condensation caused by rapid cooling of TEC in traditional solutions.

[0019] 2. High reliability of fully sealed structure: Abandoning the traditional vent valve solution, an elastic airbag is used to balance the air pressure in the internal space of the fully sealed lamp body. This maintains a high level of fully sealed dustproof and waterproof performance, and solves the problem of internal and external pressure difference caused by thermal expansion and contraction, avoiding the risk of moisture being drawn in through the vent valve.

[0020] 3. Intelligent hierarchical protection: By setting control thresholds to start preheating when the real-time humidity is greater than the first humidity threshold and to shut down preheating when the real-time humidity is less than the second humidity threshold, as well as setting a hierarchical strategy to set standby buffer when the real-time humidity is within the buffer humidity range and alarm defoaming when the real-time humidity is greater than the extreme humidity threshold, multi-level humidity management from active prevention to passive protection is realized.

[0021] 4. Avoid frequent equipment start-ups and shutdowns: The buffer humidity range setting effectively prevents the light source temperature control unit from frequently starting and stopping near the threshold, extending the equipment's lifespan and reducing energy consumption.

[0022] 5. Ensure light source safety: Automatically prevents or forcibly extinguishes bubbles under extreme humidity conditions, eliminating the risk of laser light source burning out due to short circuit caused by water vapor. Attached Figure Description

[0030] Please see Figures 1 to 3 The laser lamp includes a fully sealed lamp body 10 and a laser source 20 disposed in the fully sealed lamp body 10. The humidity control system 101 inside the laser lamp according to this embodiment of the invention includes: The controller 1 is installed in the fully sealed lamp body 10 and electrically connected to the laser light source 20; A pressure balancing unit 2 is disposed on and sealed in communication with the fully sealed lamp body 10. The pressure balancing unit 2 includes an elastic airbag that communicates with the internal space of the fully sealed lamp body 10. The light source temperature control unit 3 is installed on the laser source 20 and electrically connected to the controller 1. The light source temperature control unit 3 is used to collect and adjust the real-time light source temperature of the laser source 20. The controller 1 is used to control the light source temperature control unit 3 to cool or heat the laser source 20 when the real-time light source temperature is greater than the first temperature threshold or less than the second temperature threshold, so as to control the light source temperature of the laser source 20 within the normal temperature range. A humidity control unit 4, installed within the fully sealed lamp body 10 and electrically connected to the controller 1, is used to collect and adjust the real-time humidity of the internal space of the fully sealed lamp body 10. The controller 1 is used to: control the humidity control unit 4 to heat or not heat the internal space when the real-time humidity is greater than a first humidity threshold or less than or equal to a second humidity threshold, so as to control the humidity in the fully sealed lamp body 10 to be less than or equal to the second humidity threshold; and control the humidity control unit 4 to be in standby mode when the real-time humidity is within a buffer humidity range. The humidity warning unit 5 is installed on the fully sealed lamp body 10 and electrically connected to the controller 1. The controller 1 is used to: control the humidity warning unit 5 to issue an alarm and keep the laser light source 20 off when the real-time humidity is greater than the limit humidity threshold and the laser light source 20 is off; control the humidity warning unit 5 to issue an alarm and turn off the laser light source 20 when the real-time humidity is greater than the limit humidity threshold and the laser light source 20 is on; and deactivate the alarm of the humidity warning unit 5 and turn on the laser light source 20 when the real-time humidity is less than the first humidity threshold. Among them, the first humidity threshold is greater than the second humidity threshold, the second humidity threshold is less than or equal to the minimum value of the buffer humidity range, and the extreme humidity threshold is greater than or equal to the maximum value of the buffer humidity range.

[0031] The humidity control system 101 inside the laser lamp according to this embodiment of the invention has the following beneficial effects: 1. Effectively prevents condensation: By controlling the temperature control unit 4 to preheat the internal space of the fully sealed lamp body 10 when the real-time humidity is greater than the first humidity threshold, the humidity of the internal space is actively reduced before cooling, which fundamentally eliminates the conditions for condensation and avoids the problem of water vapor condensation caused by rapid cooling of TEC in traditional solutions.

[0032] 2. High reliability of fully sealed structure: Abandoning the traditional vent valve solution, an elastic airbag is used to balance the air pressure in the internal space of the fully sealed lamp body 10. This maintains a high level of fully sealed dustproof and waterproof performance, solves the problem of internal and external pressure difference caused by thermal expansion and contraction, and avoids the risk of moisture being drawn in through the vent valve.

[0033] 3. Intelligent hierarchical protection: By setting control thresholds to start preheating when the real-time humidity is greater than the first humidity threshold and to shut down preheating when the real-time humidity is less than the second humidity threshold, as well as setting a hierarchical strategy to set standby buffer when the real-time humidity is within the buffer humidity range and alarm defoaming when the real-time humidity is greater than the extreme humidity threshold, multi-level humidity management from active prevention to passive protection is realized.

[0034] 4. Avoid frequent equipment start-ups and shutdowns: The buffer humidity range setting effectively prevents the light source temperature control unit 3 from frequently starting and stopping near the threshold, extending the equipment's service life and reducing energy consumption.

[0035] 5. Ensure light source safety: Automatically prevents or forcibly extinguishes bubbles under extreme humidity conditions, eliminating the risk of the laser light source 20 burning out due to short circuit caused by water vapor.

[0036] The humidity control system 101 for the internal humidity of the laser lamp in this embodiment of the invention can be widely used in various outdoor high-power laser lamps (including LED lamps), especially suitable for scenarios with high requirements for waterproofing and moisture-proofing, such as cultural and tourism lighting, stage lighting, and landmark lasers. It has good industrial practical value and market promotion prospects.

[0037] Specifically, the fully sealed lamp body 10 can be made of aluminum alloy, with silicone rubber sealing rings at all joints, achieving an IP66 protection rating to ensure the high requirements of waterproofing, dustproofing, and lifespan for outdoor applications. The laser light source 20 can be an RGB laser light source with a rated power of 850W, ensuring the high power output requirements of the laser light.

[0038] The actual structure and arrangement of the fully sealed lamp body 10 and the laser light source 20 do not involve the core inventive points of this invention. Please refer to the laser lamps in the prior art. They will not be described in detail here.

[0039] The controller 1 of this invention has temperature control function, humidity control function, alarm control and display function and light source drive control function. Various working data can be pre-stored in the controller 1, such as first temperature threshold, second temperature threshold, normal temperature range, first humidity threshold, second humidity threshold, buffer humidity range and extreme humidity threshold, etc. When controlling the corresponding unit to work, the corresponding working data can be directly read.

[0040] Of course, the laser lamp can also be equipped with an independent memory that is electrically connected to the controller 1 to store the various working data mentioned above and other data used to control the operation of the laser lamp, which can provide more storage space and reduce the storage burden on the controller 1.

[0041] Furthermore, the controller 1 includes an integrated temperature control module, humidity control module, alarm control module, and light source control module. The temperature control module is electrically connected to the light source temperature control unit 3, the humidity control module is electrically connected to the humidity control unit 4, the alarm control module is electrically connected to the humidity warning unit 5, and the light source control module is electrically connected to the laser light source 20. In this way, the actual operation of the above-mentioned units can be controlled by each control module.

[0042] In one embodiment, the controller 1 can also be divided into multiple control modules as described above, and deployed in the light source temperature control unit 3, humidity control unit 4, and humidity warning unit 5 as part of each unit, so that each unit can independently perform the corresponding task.

[0043] In one embodiment, controller 1 can be an MCU (Microcontroller Unit 4) used to accurately and efficiently control the operation of the entire laser light.

[0044] In this embodiment of the invention, the elastic airbag, which serves as the air pressure balancing unit 2, is connected to the internal space of the fully sealed lamp body 10 through a connecting pipe. When the air pressure inside the fully sealed lamp body 10 increases or decreases due to temperature changes, the elastic airbag expands or contracts accordingly to balance the internal and external air pressure difference of the fully sealed lamp body 10, thereby preventing the fully sealed lamp body 10 from deforming or failing to seal due to the fully sealed structure.

[0045] In one embodiment, the volume of the elastic airbag is 3% to 20% of the volume of the internal space of the fully sealed lamp body 10. This can effectively balance the air pressure and control the volume of the elastic airbag, reducing the space occupied by the laser lamp and promoting the miniaturization of the laser lamp.

[0046] Furthermore, the volume of the elastic airbag is 5% to 15% of the volume of the internal space.

[0047] In one embodiment, the elastic airbag is made of aging-resistant silicone rubber, which ensures both good deformation capacity and service life of the elastic airbag.

[0048] Please see Figure 3 In one embodiment, the light source temperature control unit 3 includes: A temperature sensor 301, mounted on the laser source 20 and electrically connected to the controller 1, is used to collect the real-time temperature of the laser source 20; and Thermoelectric cooler (TEC), which is mounted on the laser source 20 and electrically connected to the controller 1, is used to cool or heat the laser source 20. Controller 1 is used for: Receive the real-time light source temperature and obtain the pre-stored first temperature threshold and second temperature threshold; Compare the real-time light source temperature with the first and second temperature thresholds; When the real-time light source temperature exceeds a first temperature threshold, the semiconductor cooling chip 302 is controlled to cool the laser light source 20 until the real-time light source temperature drops to within the normal temperature range; and When the real-time light source temperature is lower than the second temperature threshold, the semiconductor cooling chip 302 is controlled to heat the laser light source 20 until the real-time light source temperature rises to the normal temperature range.

[0049] Specifically, the temperature sensor 301 and the semiconductor cooling chip 302 can be attached to the corresponding positions of the laser source 20, such as the bottom of the laser source 20, to accurately detect the temperature of the laser source 20 and effectively cool or heat the laser source 20.

[0050] In this embodiment of the invention, the first temperature threshold can be 35°C, the second temperature threshold can be 30°C, and the normal temperature range can be 30°C to 35°C. That is, the controller 1 controls the semiconductor cooling chip 302 to cool or heat according to the real-time light source temperature of the laser light source 20 collected by the temperature sensor 301. When the controller 1 confirms that the temperature of the laser source 20 exceeds 35°C based on the real-time light source temperature of the laser source 20 collected by the temperature sensor 301, it activates the cooling mode of the semiconductor cooling chip 302 to cool down the laser source 20. When the controller 1 confirms that the temperature of the laser source 20 is below 30°C based on the real-time light source temperature collected by the temperature sensor 301, it activates the heating mode of the semiconductor cooling chip 302 to raise the temperature of the laser source 20, thereby maintaining the temperature of the laser source 20 within the range of 30°C to 35°C and ensuring the normal operation of the laser source 20.

[0051] Please see Figure 3 In one embodiment, the humidity control unit 4 includes: A humidity sensor 401, installed inside the fully sealed lamp body 10 and electrically connected to the controller 1, is used to collect the real-time humidity of the internal space of the fully sealed lamp body 10; and The heating module 402, which is installed in the fully sealed lamp body 10 and electrically connected to the controller 1, is used to heat the internal space or stop heating. Controller 1 is used for: Receive real-time humidity and obtain the pre-stored first humidity threshold and second humidity threshold; Compare the real-time humidity with the first humidity threshold and the second humidity threshold; When the real-time humidity is greater than a first humidity threshold, the heating module 402 is activated to heat the internal space until the real-time humidity drops to less than or equal to a second humidity threshold; and When the real-time humidity is less than or equal to the second humidity threshold, if the heating module 402 has been started, it will be turned off; if the heating module 402 has not been started, it will remain turned off.

[0052] Specifically, the humidity sensor 401 and the heating module 402 can be set at corresponding positions in the fully sealed lamp body 10, such as in the bottom space of the fully sealed lamp body 10 (i.e., the space where the laser light source 20 is not set), so as to accurately detect the humidity in the internal space of the fully sealed lamp body 10 and effectively heat the internal space, while avoiding affecting the normal light emission of the laser light source 20.

[0053] In one embodiment, the heating module 402 is a diode with a heat sink, which has both preheating and heating capabilities and can control the cost of the heating module 402.

[0054] In this embodiment of the invention, the first humidity threshold can be 60%, the second humidity threshold can be 55%, and the buffer humidity range can be 55% to 75%. That is, the controller 1 controls the heating module 402 to heat the internal space, stop heating, or go into standby mode based on the real-time humidity of the internal space of the fully sealed lamp body 10 collected by the humidity sensor 401. When the controller 1 confirms that the humidity of the internal space is greater than 60% based on the real-time humidity collected by the humidity sensor 401, it starts the heating module 402 to heat the internal space and reduce the relative humidity by raising the temperature of the internal space. When the controller 1 confirms that the humidity of the internal space is 55% or below based on the real-time humidity collected by the humidity sensor 401, if the heating module 402 has been started, the controller 1 will turn off the heating module 402 to stop heating; if the heating module 402 has not been started, the controller 1 will keep it off to reduce the energy consumption of the laser lamp. When the controller 1 confirms that the humidity of the internal space is within the range of 55% to 75% based on the real-time humidity collected by the humidity sensor 401, it controls the heating module 402 to standby / off state to avoid frequent start-up and shutdown of the heating module 402 due to humidity fluctuations near the threshold.

[0055] In this embodiment of the invention, the extreme humidity threshold can be 75%, and the humidity warning unit 5 can be an audible and visual alarm unit, such as a buzzer and / or warning light installed at the corresponding position of the fully sealed lamp body 10, which can emit audible and / or visual alarms. The controller 1 controls the operation of the humidity warning unit 5 according to the real-time humidity of the internal space of the fully sealed lamp body 10 collected by the humidity sensor 401. When the controller 1 confirms that the humidity of the internal space is greater than 75% based on the real-time humidity collected by the humidity sensor 401, the humidity warning unit 5 issues an alarm for "high humidity". For example, the buzzer sounds an alarm or the warning light emits a corresponding warning light. If the laser light source 20 is not turned on at this time, the laser light source 20 is prohibited from igniting. If the laser light source 20 is in the lit state (i.e., it is turned on), the light source is automatically extinguished (the light source is turned off), and the heating module 402 is started to continue heating. When the controller 1 confirms that the humidity of the internal space has dropped to 60% or below based on the real-time humidity collected by the humidity sensor 401, it will deactivate the alarm of the humidity warning unit 5 and allow the laser light source 20 bulbs to turn on the light tube, and continue to turn on the heating module 402 until the humidity drops to below 55% before turning it off.

[0056] For example, the working principle of the humidity control system 101 inside the laser lamp in this embodiment of the invention is as follows: Under normal operating conditions, the controller 1 controls the semiconductor cooling chip 302 to maintain the temperature of the laser light source 20 within the range of 30℃ to 35℃ based on the temperature detection of the laser light source 20 by the temperature sensor 301. At the same time, the humidity sensor 401 continuously monitors the humidity inside the fully sealed lamp body 10.

[0057] If the ambient temperature exceeds 35°C and the humidity is greater than 75%, and the laser light source 20 receives a bubble signal, under normal circumstances, the controller 1 will directly control the semiconductor cooling chip 302 to cool the laser light source 20 rapidly. However, since the humidity inside the fully sealed lamp body 10 is too high at this time, in this solution, the controller 1 will first control the heating module 402 to start in advance to heat the internal space of the fully sealed lamp body 10, so that the temperature of the internal space increases to reduce the relative humidity. When the relative humidity drops below 75%, the semiconductor cooling chip 302 will be turned on, thereby avoiding the problem of water vapor condensing on the surface of the laser light source 20 when the semiconductor cooling chip 302 is turned on to rapidly cool the laser light source 20.

[0058] Once the relative humidity drops below 55%, controller 1 shuts down heating module 402, and the system enters a buffer humidity range (55%–75%). Within this range, heating module 402 will not start frequently, avoiding energy waste and equipment damage. However, if the humidity is detected to exceed 75%, it indicates that the external environment of the laser light is extremely harsh. Controller 1 then controls humidity warning unit 5 to automatically issue an alarm and prohibits the laser light source 20 from activating its bulb or forcibly extinguishes the bulb. Only after heating module 402 is activated to heat the internal space until the humidity drops below 60% can the laser light source 20 resume normal operation.

[0059] Throughout the entire control process, the elastic airbag expands or contracts adaptively with changes in internal temperature, always maintaining the internal and external air pressure balance of the fully sealed lamp body 10.

[0060] Please see Figure 3 and Figure 4 The method for controlling the internal humidity of a laser lamp according to this invention is applied to the control system 101 for the internal humidity of a laser lamp in any of the above embodiments. The method for controlling the internal humidity of a laser lamp includes the following steps: S10: Control the light source temperature control unit 3 to collect the real-time light source temperature of the laser light source 20, obtain the pre-stored first temperature threshold and second temperature threshold, and compare the real-time light source temperature with the first temperature threshold and the second temperature threshold. S20: When the real-time light source temperature is greater than the first temperature threshold, control the light source temperature control unit 3 to cool down the laser light source 20 until the real-time light source temperature drops to the normal temperature range. When the real-time light source temperature is less than the second temperature threshold, control the light source temperature control unit 3 to heat up the laser light source 20 until the real-time light source temperature rises to the normal temperature range. S30: Control the humidity control unit 4 to collect the real-time humidity of the internal space of the fully sealed lamp body 10, obtain the pre-stored first humidity threshold, second humidity threshold, buffer humidity range and extreme humidity threshold, compare the real-time humidity with the first humidity threshold, second humidity threshold, buffer humidity range and extreme humidity threshold, wherein the first humidity threshold is greater than the second humidity threshold, the second humidity threshold is less than or equal to the minimum value of the buffer humidity range, and the extreme humidity threshold is greater than or equal to the maximum value of the buffer humidity range; S40: When the real-time humidity is greater than the first humidity threshold, activate the humidity control unit 4 to heat the internal space until the real-time humidity drops to less than or equal to the second humidity threshold. When the real-time humidity is less than or equal to the second humidity threshold, if the humidity control unit 4 has been activated, deactivate it; otherwise, keep it deactivated. When the real-time humidity is within the buffer humidity range, control the humidity control unit 4 to be in standby mode. S50: When the real-time humidity is greater than the limit humidity threshold and the laser light source 20 is turned off, the humidity warning unit 5 is controlled to issue an alarm and keep the laser light source 20 off. When the real-time humidity is greater than the limit humidity threshold and the laser light source 20 is turned on, the humidity warning unit 5 is controlled to issue an alarm and turn off the laser light source 20. When the real-time humidity is less than the first humidity threshold, the alarm of the humidity warning unit 5 is deactivated and the laser light source 20 is turned on.

[0061] The method for controlling the internal humidity of a laser lamp according to embodiments of the present invention has the following beneficial effects: 1. Effectively prevents condensation: By controlling the temperature control unit 4 to preheat the internal space of the fully sealed lamp body 10 when the real-time humidity is greater than the first humidity threshold, the humidity of the internal space is actively reduced before cooling, which fundamentally eliminates the conditions for condensation and avoids the problem of water vapor condensation caused by rapid cooling of TEC in traditional solutions.

[0062] 2. High reliability of fully sealed structure: Abandoning the traditional vent valve solution, an elastic airbag is used to balance the air pressure in the internal space of the fully sealed lamp body 10. This maintains a high level of fully sealed dustproof and waterproof performance, solves the problem of internal and external pressure difference caused by thermal expansion and contraction, and avoids the risk of moisture being drawn in through the vent valve.

[0063] 3. Intelligent hierarchical protection: By setting control thresholds to start preheating when the real-time humidity is greater than the first humidity threshold and to shut down preheating when the real-time humidity is less than the second humidity threshold, as well as setting a hierarchical strategy to set standby buffer when the real-time humidity is within the buffer humidity range and alarm defoaming when the real-time humidity is greater than the extreme humidity threshold, multi-level humidity management from active prevention to passive protection is realized.

[0064] 4. Avoid frequent equipment start-ups and shutdowns: The buffer humidity range setting effectively prevents the light source temperature control unit 3 from frequently starting and stopping near the threshold, extending the equipment's service life and reducing energy consumption.

[0065] 5. Ensure light source safety: Automatically prevents or forcibly extinguishes bubbles under extreme humidity conditions, eliminating the risk of the laser light source 20 burning out due to short circuit caused by water vapor.

[0066] The method for controlling the internal humidity of the laser lamp in this embodiment of the invention can be applied to controller 1 in the control system and executed by controller 1.

[0067] For example, the method for controlling the humidity inside a laser lamp according to an embodiment of the present invention can be summarized as follows: Step S1: The controller 1 monitors the temperature of the laser source 20 in real time through the temperature sensor 301. When the temperature is >35℃, it controls the semiconductor cooling chip 302 to cool down. When the temperature is <30℃, it controls the semiconductor cooling chip 302 to heat up, so as to maintain the temperature of the laser source 20 within the range of 30℃ to 35℃. Step S2: Controller 1 monitors the humidity inside the fully sealed lamp body 10 in real time via humidity sensor 401; Step S3: When the humidity is >60%, the controller 1 starts the heating module 402 to heat; Step S4: When the humidity drops to ≤55%, controller 1 controls heating module 402 to turn off; Step S5: When the humidity is between 55% and 75%, the heating module 402 remains in its current state to avoid frequent start-stop. Step S6: When the humidity is >75%, the controller 1 controls the humidity warning unit 5 to issue an alarm display of "humidity too high". The controller 1 disables the laser light source 20 from lighting up. If the laser light source 20 is currently in a lit state, the controller 1 will turn off the light. Step S7: When the humidity drops to <60%, the controller 1 deactivates the alarm of the humidity warning unit 5 and restores the dotting permission of the laser light source 20.

[0068] During the execution of the above steps, the elastic airbag expands or contracts adaptively with the air pressure changes inside the fully sealed lamp body 10, balancing the internal and external air pressures.

[0069] Please see Figures 1 to 3 The high-power RGB laser light 100 of this invention includes: Base 30; A fully sealed lamp body 10 is rotatably mounted on the base 30, and a laser light source 20 is disposed within the fully sealed lamp body 10; and The control system 101 for the internal humidity of the laser lamp in any of the above embodiments is disposed in the fully sealed lamp body 10 and on the fully sealed lamp body 10.

[0070] The high-power RGB laser lamp 100 of this invention has the following beneficial effects: 1. Effectively prevents condensation: By controlling the temperature control unit 4 to preheat the internal space of the fully sealed lamp body 10 when the real-time humidity is greater than the first humidity threshold, the humidity of the internal space is actively reduced before cooling, which fundamentally eliminates the conditions for condensation and avoids the problem of water vapor condensation caused by rapid cooling of TEC in traditional solutions.

[0071] 2. High reliability of fully sealed structure: Abandoning the traditional vent valve solution, an elastic airbag is used to balance the air pressure in the internal space of the fully sealed lamp body 10. This maintains a high level of fully sealed dustproof and waterproof performance, solves the problem of internal and external pressure difference caused by thermal expansion and contraction, and avoids the risk of moisture being drawn in through the vent valve.

[0072] 3. Intelligent hierarchical protection: By setting control thresholds to start preheating when the real-time humidity is greater than the first humidity threshold and to shut down preheating when the real-time humidity is less than the second humidity threshold, as well as setting a hierarchical strategy to set standby buffer when the real-time humidity is within the buffer humidity range and alarm defoaming when the real-time humidity is greater than the extreme humidity threshold, multi-level humidity management from active prevention to passive protection is realized.

[0073] 4. Avoid frequent equipment start-ups and shutdowns: The buffer humidity range setting effectively prevents the light source temperature control unit 3 from frequently starting and stopping near the threshold, extending the equipment's service life and reducing energy consumption.

[0074] 5. Ensure light source safety: Automatically prevents or forcibly extinguishes bubbles under extreme humidity conditions, eliminating the risk of the laser light source 20 burning out due to short circuit caused by water vapor.

[0075] Please see Figure 1 and Figure 2 In one embodiment, the high-power RGB laser light 100 further includes: U-shaped support arm 40, which includes a bottom support arm 41 rotatably mounted on the base 30 and two side support arms 42 mounted at both ends of the bottom support arm 41. The fully sealed lamp body 10 is rotatably mounted between the two side support arms 42. The air pressure balance unit 2 is mounted on one side of the fully sealed lamp body 10 and located in one of the side support arms 42.

[0076] The bottom support arm 41 is sealed to the two side support arms 42, and the two side support arms 42 are sealed to the fully sealed lamp body 10, ensuring the overall sealing effect of the high-power RGB laser lamp 100.

[0077] By placing the air pressure balancing unit 2 in a side support arm 42, it is possible to facilitate direct connection between the air pressure balancing unit 2 and the fully sealed lamp body 10, effectively utilize the internal space of the side support arm 42, and protect the air pressure balancing unit 2 from external damage, dirt, etc., thereby extending the service life of the air pressure balancing unit 2.

[0078] Please see Figure 1 and Figure 2 In one embodiment, the other side support arm 42 is provided with a connecting pipe 43 that connects the fully sealed lamp body 10 and the base 30.

[0079] Specifically, the connecting pipe 43 can be a silicone tube, which can be used for electrical wiring between the base 30 and the fully sealed lamp body 10 to ensure the centralized and orderly arrangement of cables, and also for gas communication and exchange between the base 30 and the fully sealed lamp body 10 to balance the internal and external air pressure and carry out effective heat exchange.

[0080] For example, the application scenario test of the high-power RGB laser lamp 100 of this embodiment of the invention is as follows: Under simulated outdoor high temperature and high humidity conditions of 40℃ and 85% relative humidity, when the controller 1 detects that the humidity inside the fully sealed lamp body 10 is >60%, the heating module 402 is activated, the temperature inside the fully sealed lamp body 10 rises by about 5℃ to 8℃, and the relative humidity drops from 75% to 52% to 55%. Subsequently, the semiconductor cooling chip 302 starts cooling to reduce the temperature of the laser light source 20, and there is no condensation on the surface of the laser light source 20.

[0081] When the humidity inside the fully sealed lamp body 10 continues to rise above 75%, the controller 1 controls the laser light source 20 to extinguish the bubbles and controls the humidity warning unit 5 to issue an alarm. After the humidity drops below 60%, the operation of the laser light source 20 is restored. The laser light source 20 is not damaged at all during the entire process, and its reliability has been verified in practice.
