[0030] In this embodiment, as shown in Fig. 3As shown, the opening is provided with an air duct 80, which is communicated with the inside and outside of the operation space and has at least one turning part with the operation space to avoid the light from the outside of the operation space entering the operation space and affecting the production of the film. Specifically, the opposite two walls 10 are provided with openings, and the air duct 80 is arranged at the top of the operation space, and the two ends thereof pass through the openings and are communicated with the outside of the operation space. The air duct 80 is also provided with an air outlet at the floor 30, and the plane of the air outlet is perpendicular to the plane of the opening, so that the external light cannot enter the operation space through the air duct 80. The two openings are coaxially arranged, and can also be arranged in a non-coaxial manner, that is, the turning part can also be realized by the design of the air duct 80 itself. In other embodiments, the air duct 80 can also be arranged outside the operation space and send air or exhaust air to the operation space through the opening. The specific size and position of the opening are set according to the actual demand or the layout of the workshop, so as to avoid the external light entering the operation space from the air duct 80 when the opening is too large or too close.

[0031] In this embodiment, a fan 110 is arranged in the air duct 80 to facilitate efficient air exhaust and air supply and ensure air circulation in the operation space. Specifically, the fan 110 is a bidirectional rotating fan 110 and can realize air exhaust and air supply. In other embodiments, two fans 110 can also be arranged to realize air exhaust and air supply. The two ends of the air duct 80 are provided with a cover 120 to prevent foreign matters outside the operation space from entering the air duct 80 and damaging the fan 110, and even entering the operation space to affect the production. Specifically, the two ends of the air duct 80 are arranged at the openings of the walls 10 and are communicated with the outside, and the cover 120 is fixed on the walls 10 at positions corresponding to the openings.

[0032] In this embodiment, a partition plate 803 is arranged in the air duct 80, which divides the air duct 80 into an air inlet section 801 and an air outlet section 802. The air inlet section 801 and the air outlet section 802 are both communicated with the operation space, and the fan 110 is arranged in the air inlet section 801 and the air outlet section 802 to realize air supply and air exhaust, respectively. Specifically, the partition plate 803 is arranged directly above the air outlet.

Preferably, the wind guide vane can swing relative to the partition plate 803 to guide the gas in the air inlet section 801 into the operation space, or guide the gas in the operation space into the air outlet section 802. The swing amplitude of the wind guide vane is between 0 degrees and 90 degrees. In other embodiments, the air inlet is provided with a cover 120. The gas in the operation space is first filtered by the cover 120 and then guided into the air duct 80 by the wind guide 130 to prevent damage and blockage of the wind guide vanes by waste materials.

[0034] In this embodiment, the wall 10 is provided with a light shield at the position of the door to avoid the influence of other light sources entering through the gap between the door and the wall 10 on the film production. In some embodiments, the wall 10 is provided with a ventilated window, and the window is provided with a light-shielding coating, which can be black or other light-shielding materials. When producing and processing, the window is closed, and the light-shielding coating can shield the external light source outside the operation space; after completing the production and processing, the window is opened to facilitate ventilation.

[0035] The working principle of the film production workshop according to the present embodiment is as follows:

[0036] Before production, the doors and windows are closed to prevent light sources other than the light emitting device 40 from entering the operation space and affecting production, and to control the light emitting device 40 to emit uniform spectrum distribution of illumination light towards the floor 30. The operator sets the predetermined value under the illumination light, such as setting the preset temperature to 16℃-31℃ and the preset humidity to 50±10%RH when preparing UV adhesion-reducing film, and then adjusts the light emitting device 40 to processing mode to emit yellow light with a wavelength range of 570nm-590nm.

[0037] During production, the light emitting device 40 is controlled to emit yellow light with a constant wavelength towards the floor 30. The temperature sensor 70 and the humidity sensor 90 detect and control the environmental temperature and humidity of the operation space, and at the same time, the corresponding operation of the fan 110 is controlled to ensure that the environment of the operation space meets the production requirements. Specifically:

[0038] When the temperature sensor 70 detects that the ambient temperature of the operation space is higher than the preset temperature, the temperature sensor 70 controls the surface cooler 50 to work for refrigeration until the preset temperature is reached, and then the temperature sensor 70 controls the surface cooler 50 to be turned off; when the temperature sensor 70 detects that the ambient temperature of the operation space is lower than the preset temperature, the temperature sensor 70 controls the heater 60 to work for heating until the ambient temperature of the operation space reaches the preset temperature, and then the temperature sensor 70 controls the heater 60 to be turned off. Through the cooperation between the temperature sensor 70 and the surface cooler 50 and the heater 60, it is ensured that the operation space is kept within the predetermined temperature range, and the film defects and waste caused by temperature factors are reduced. At the same time, the fan 110 of the air inlet section 801 can also be controlled to work for air supply, so as to further improve the efficiency of refrigeration or heating.

[0039] When the humidity sensor 90 detects that the humidity of the operation space is lower than the preset humidity, the humidity sensor 90 controls the humidifier 100 to work until the preset humidity is reached. During the production process, the ambient temperature and humidity of the operation space are always kept within the predetermined range, and the fan 110 works correspondingly to ensure the circulation of the gas in the operation space.

[0040] Until the current production work is completed, the light emitting device 40 is controlled to stop emitting the light of the predetermined wavelength, and the illumination light with uniform spectrum distribution is emitted again to end the current processing. When the next production work is needed, the related preset values are adjusted and the above steps are repeated.

[0041] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application should be covered within the protection scope of the present application.
