[0032] Reference Figures 2 to 4This utility model proposes an integrated surface light source for air ducts, comprising:

[0033] The front panel 10 of the air duct is provided with a light guide groove 11, and a light lamp groove 12 is recessed at one end of the bottom of the light guide groove 11.

[0034] Lighting element 20, which is installed in the lighting groove 12;

[0035] A reflective sheet 30 and a light guide plate 40 are mounted within the light guide groove 11, with the light guide plate 40 positioned on the side of the reflective sheet 30 facing away from the front panel 10 of the air duct; and

[0036] A diffuser plate 50 is attached to the front panel 10 of the air duct and covers the openings of the light guide groove 11 and the light groove 12.

[0037] The integrated surface light source of this utility model includes a duct front plate 10, a light element 20, a reflector 30, a light guide plate 40, and a diffuser plate 50. The duct front plate 10 is provided with a light guide groove 11, and a light groove 12 is recessed at the bottom of the light guide groove 11. The light element 20 is installed in the light groove 12, and the reflector 30 and the light guide plate 40 are installed in the light guide groove 11, with the light guide plate 40 located on the side of the reflector 30 away from the duct front plate 10. Furthermore, the diffuser plate 50 is pasted onto the duct front plate 10 and covers the openings of the light guide groove 11 and the light groove 12, thereby completing the assembly of the integrated surface light source. Compared with the existing technical solution of sealing the edges with transparent tape and then installing an aluminum alloy or plastic frame, the technical solution of this application facilitates the assembly of the integrated surface light source and improves the installation efficiency of the integrated surface light source.

[0038] It should be noted that the area of ​​the light guide groove 11 can be slightly larger than the area of ​​the light guide plate 40 and / or the reflector 30, and the area of ​​the light groove 12 is slightly larger than the light element 20. That is, the light guide plate 40 and / or the reflector 30 are not completely fixed in the light guide groove 11, the light element 20 can have a small range of movement in the light groove 12, and the light guide plate 40 and / or the reflector 30 can have a small range of movement in the light guide groove 11. Since the diffuser plate 50 is sealed and connected to the opening of the light guide groove 11 and the light groove 12, the diffuser plate 50 is used to limit the light element 20 and the light guide plate 40 in the thickness direction, so it does not affect the normal operation of the light guide plate 40 and the light element 20.

[0039] Of course, in other embodiments, the size of the light guide groove 11 is adapted to the size of the light guide plate 40, and the size of the light groove 12 is adapted to the size of the light component 20. When the light component 20 and the light guide plate 40 are respectively installed in the light groove 12 and the light guide groove 11, the light component 20 and the light guide plate 40 are respectively locked in the light groove 12 and the light guide groove 11 to limit and fix the light component 20 and the light guide plate 40.

[0040] Specifically, the front panel 10 of the air duct is provided with a dispensing groove 13, and the diffuser plate 50 is attached to the front panel 10 of the air duct through the dispensing groove 13. Understandably, by providing the dispensing groove 13, the adhesive can be contained within it, thereby reducing the amount of adhesive overflowing when the diffuser plate 50 is attached to the front panel 10 of the air duct. This reduces the amount of adhesive overflowing into the light guide groove 11 and the light groove 12, and also reduces the amount of adhesive overflowing onto the outer periphery of the diffuser plate 50 and the front panel 10 of the air duct. This further reduces the need for subsequent work such as cutting and repairing the solidified adhesive after the assembly of the integrated surface light source, thus facilitating the assembly of the integrated surface light source.

[0041] Reference Figures 4 to 6 Furthermore, the adhesive groove 13 is located on the side of the front panel 10 facing the diffuser plate 50. That is, the front panel 10 and the diffuser plate 50 are glued and fixed on opposite sides. Compared with the technical solution of gluing and fixing the diffuser plate 50 to the front panel 10 via its periphery, the adhesive groove 13 being located on the side of the front panel 10 facing the diffuser plate 50 increases the bonding area between the front panel 10 and the diffuser plate 50, thereby improving the installation strength of the diffuser plate 50 and thus improving the stability and reliability of the integrated surface light source of the air duct.

[0042] Furthermore, the light guide groove 11 and the light slot 12 are located inside the adhesive dispensing groove 13. That is, the adhesive dispensing groove 13 is arranged circumferentially along the light guide groove 11 and the light slot 12, thereby further increasing the bonding area between the diffuser plate 50 and the front panel of the air duct 10. Moreover, the adhesive dispensing groove 13 is arranged circumferentially around the light guide groove 11 and the light slot 12, thereby increasing the sealing effect between the diffuser plate 50 and the front panel of the air duct 10, and thus improving the waterproof effect of the integrated surface light source of the air duct.

[0043] In one embodiment, a plurality of support protrusions 14 are spaced apart on the inner peripheral wall of the light guide groove 11. The support protrusions 14 extend along the direction close to the diffuser plate 50 and protrude from the opening of the light guide groove 11. The plurality of support protrusions 14 are arranged in a ring around the adhesive dispensing groove 13. Understandably, when the diffuser plate 50 is bonded to the front panel 10 of the air duct, adhesive is first placed in the adhesive dispensing groove 13, and then the diffuser plate 50 is pressed onto the front panel 10 of the air duct, thereby achieving bonding and fixation between the diffuser plate 50 and the front panel 10 of the air duct. However, during the pressing process of the diffuser plate 50, the diffuser plate 50 inevitably undergoes concave deformation, which can easily cause the adhesive in the adhesive dispensing groove 13 to overflow into the light guide groove 11 and the light slot 12. Then, when the pressure on the diffuser plate 50 disappears and the diffuser plate 50 returns to its initial state, the amount of adhesive in the adhesive dispensing groove 13 decreases, which can easily lead to misalignment between the diffuser plate 50 and the front panel 10 of the air duct. If there is less adhesive between the diffuser plate 50 and the front panel 10 of the air duct, the bonding between them may become weak, making the diffuser plate 50 prone to detachment. Therefore, in this application, multiple support protrusions 14 are provided at intervals along the circumference of the dispensing groove 13. These support protrusions 14 reduce the probability of the diffuser plate 50 deforming in the area near the dispensing groove 13, thereby reducing the possibility of adhesive overflow in the dispensing groove 13. This ensures the amount of adhesive between the diffuser plate 50 and the front panel 10 of the air duct, thereby improving the bonding and fixing effect between the diffuser plate 50 and the front panel 10 of the air duct, and thus improving the stability and reliability of the integrated surface light source of the air duct.

[0044] Furthermore, the supporting protrusion 14 is flush with the side of the diffuser plate 50 facing the front panel 10 of the air duct facing the diffuser plate 50. The adhesive groove 13 is located between the supporting protrusion 14 and the outer periphery of the front panel 10 of the air duct. Therefore, by aligning the upper surface of the supporting protrusion 14 with the upper surface of the front panel 10 of the air duct, the supporting protrusion 14 and the side of the front panel 10 facing the diffuser plate 50 support the diffuser plate 50. This further reduces the possibility of deformation of the diffuser plate 50 during pressing in the area of ​​the adhesive groove 13, thereby reducing adhesive overflow in the adhesive groove 13, improving the bonding and fixing effect between the diffuser plate 50 and the front panel 10 of the air duct, and ultimately improving the stability and reliability of the integrated surface light source of the air duct.

[0045] Reference Figure 1In one embodiment, the diffuser plate 50 protrudes from the outer peripheral surface of the duct front panel 10. That is, the diffuser plate 50 is completely pressed against the duct front panel 10, forming an overhanging, roof-like structure. This ensures that the adhesive surface between the diffuser plate 50 and the duct front panel 10 is covered on the side of the diffuser plate 50 facing the duct front panel 10, preventing the adhesive surface from being directly exposed. This reduces the amount of external water entering the light guide groove 11 and the light groove 12 through the adhesive surface between the diffuser plate 50 and the duct front panel 10, thereby improving the waterproof effect of the integrated surface light source and extending its service life. Simultaneously, preventing the adhesive surface between the diffuser plate 50 and the duct front panel 10 from being directly exposed also improves the appearance of the integrated surface light source, enhancing its aesthetics and user experience.

[0046] Reference Figure 4 Preferably, the light guide plate 40 and the diffuser plate 50 are spaced apart. Understandably, if the light guide layer and the diffuser layer are in direct contact, uneven local bonding pressure will cause abnormal light scattering at the contact point, forming uneven patches of light and dark. Traditional surface light sources require strict control of the parallelism between the light guide layer and the diffuser layer; even slight assembly deviations can lead to uneven light emission, demanding extremely high precision in manual operation. Therefore, by spaced apart the light guide plate 40 and the diffuser plate 50, optical effects can be guaranteed without precise leveling, significantly reducing assembly difficulty and improving the assembly effect of the duct-integrated surface light source. Furthermore, the gap between the light guide plate 40 and the diffuser plate 50 provides a dissipation channel for the heat generated by the lamp element 20, preventing heat accumulation in the enclosed space that could cause yellowing or deformation of the light guide layer, thereby extending the service life of the duct-integrated surface light source.

[0047] Reference Figure 6 Specifically, it can be understood that the lighting component 20 is electrically connected to a power source within the cooling equipment or an external power source via a wire, thereby providing power to the lighting component 20. Therefore, in one embodiment, the front panel 10 of the air duct is provided with a notch 15, through which the power cord of the lighting component 20 is connected to the power source, and the notch 15 is sealed with adhesive. In this way, the power cord of the lighting component 20 passes through the notch 15 and is electrically connected to the power source. Simultaneously, the notch 15 is sealed with adhesive, thereby greatly reducing the entry of external water and debris into the light guide groove 11 and the lighting groove 12 through the notch 15, thus improving the waterproof effect and service life of the integrated surface light source in the air duct. The lighting component 20 can be an LED light, a lamp tube, etc.
