AI Technical Summary
When stage lights are used outdoors, vaporous water can enter the lamp body, causing fogging of the lens, waterproof panel glass, and circuit board, affecting the lighting effect and potentially causing electronic component malfunctions.
The system employs a combination of a reversible moisture-absorbing sheet, an electrostatic dehumidifier, and a vent valve within a closed cavity. The moisture-absorbing sheet absorbs moisture when humidity is high and releases moisture when humidity is low. Combined with the electrostatic dehumidifier, water vapor is electrolyzed and discharged, maintaining low humidity within the lamp body.
It effectively prevents condensation and fogging inside the lamp body, maintains lens clarity and circuit safety, reduces maintenance costs, and prevents circuit board burnout and short circuits.

[0007] Further limited, when the humidity in the cavity is greater than the humidity inside the moisture absorbing sheet, the moisture absorbing sheet is in the moisture absorbing state; when the humidity in the cavity is less than the humidity inside the moisture absorbing sheet, the moisture absorbing sheet is in the moisture releasing state.

[0016] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict, and the present application will be further described in detail below in combination with the drawings and specific embodiments.
[0017] As shown in the accompanying Figure 1 to the accompanying Figure 3 A dehumidification system of a stage lamp and a stage lamp thereof, comprising a lamp body 1 having a closed cavity 10, the cavity 10 is provided with reversible moisture absorbing sheets 2, the moisture absorbing sheets 2 are plant fiber dry sheets, the moisture absorbing sheets 2 have mutually switchable moisture absorbing state and moisture releasing state, the cavity 10 of the lamp body 1 is provided with an electrolytic dehumidifier 3, the electrolytic dehumidifier 3 is used to electrolyze the water vapor in the cavity 10 or / and the water vapor released by the moisture absorbing sheets 2 in the moisture releasing state and discharge the water vapor out of the cavity 10, the cavity 10 of the lamp body 1 is also provided with an air valve 4, the air valve 4 is used to balance the air pressure change in the cavity 10 caused by temperature or / and the air pressure change caused by the electrolytic dehumidifier 3 when the hydrolysis reaction occurs.
[0018] Due to the reversibility of the moisture absorbing sheet 2, the moisture absorbing sheet 2 can be recycled, avoiding frequent replacement in the later stage and reducing maintenance cost. It absorbs moisture in high humidity and releases moisture in low humidity to adjust humidity, which can be understood as follows: when the humidity in the cavity 10 is greater than the humidity inside the moisture absorbing sheet 2, the moisture absorbing sheet 2 is in a moisture absorbing state; when the humidity in the cavity 10 is less than the humidity inside the moisture absorbing sheet 2, the moisture absorbing sheet 2 is in a moisture releasing state, so as to keep the humidity stable; through the humidity adjusting function, the dehumidifying effect can be kept effective for a long time to deal with the condensation phenomenon, so as to avoid water mist on the lens, glass panel and circuit board of the lamp, keep the lens and glass panel visible and clear, maintain good light effect, and also prevent the circuit board from burning out and short circuit.
[0019] Although the moisture absorbing sheet 2 can quickly absorb most of the water vapor, gaseous water may still continuously enter the closed cavity 10 through the air vent valve 4, and the gaseous water will be liquefied into liquid water vapor in the cavity 10. When the moisture absorbing sheet 2 absorbs a certain saturation, it will slowly release the water vapor.
[0020] The user powers on the stage lamp to start the electrolytic dehumidifier 3, which electrolyzes and discharges the residual water vapor in the cavity 10 or / and the water vapor released by the moisture absorbing sheet 2, maintains a lower relative humidity in the lamp body 1, and thus prevents condensation and mist from forming inside the sealed cavity 10 due to humidity saturation and external environmental influence.
[0021] The present application combines the moisture absorbing sheet 2, the electrolytic dehumidifier 3 and the air vent valve 4 to make the stage lamp meet the functions of waterproofing, balanced air permeability and humidity adjusting.
[0022] As shown in the accompanying drawings Figure 4 The electrolytic dehumidifier 3 includes a shell 31 with an electrolytic reaction cavity 30, the electrolytic reaction cavity 30 is provided with an electrolyte membrane layer 32 separating it into a first reaction cavity 301 and a second reaction cavity 302, the first reaction cavity 301 communicates with the cavity 10, the second reaction cavity 302 communicates with the outside, the electrolyte membrane layer 32 has a dehumidifying side in the first reaction cavity 301 and a humidifying side in the second reaction cavity 302, the dehumidifying side of the electrolyte membrane layer 32 is connected with an anode terminal 33, and the humidifying side of the electrolyte membrane layer 32 is connected with a cathode terminal 34. Specifically, the anode terminal 33 is electrically connected with the positive electrode of a direct current power supply, the cathode terminal 34 is electrically connected with the negative electrode of the direct current power supply, after electrical connection, the electrolyte membrane starts to work, the water molecules in the dehumidifying side (anode) are decomposed into hydrogen ions (H + ) and oxygen (O2), the hydrogen ions move through the electrolyte membrane to the humidifying side (cathode), and are reduced with the oxygen in the outside to water vapor, which is discharged to the outside, so as to achieve a one-way irreversible dehumidifying effect.
[0023] In the embodiment, the opening of the second reaction cavity 302 is provided with a waterproof and air-permeable film layer 35 sealing the opening, preventing liquid water from entering the second reaction cavity 302, and further increasing the sealing property.
