Description

Technical Field

[0001] This invention relates to a fan light, belonging to the field of lighting fixture technology. Background Technology

[0002] Currently, in order to achieve a lightweight effect, most fan lights on the market use plastic for their lighting base. However, plastic lighting bases are relatively weak and are easily deformed when subjected to external forces, especially when the fan is rotating. This makes the plastic lighting base more prone to deformation, thus affecting the overall lifespan of the fan light.

[0003] In view of this, it is indeed necessary to propose a new type of fan light to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a fan light that enhances the structural strength of the fan light chassis.

[0005] To achieve the above objectives, the present invention provides a fan light, the fan light comprising: The lighting assembly includes a chassis, a drive module, a light source module integrated on the chassis, and a mask fixedly connected to the chassis. The chassis and the mask together form a receiving cavity for housing the light source module, and the mask is configured to emit the emitted light from the light source module. A fan assembly includes a turntable, a fan blade structure disposed on the turntable and operable to open or close relative to the turntable, and a drive member connected to the turntable, the drive member being configured to drive the turntable to rotate and cause the fan blade structure to open or close relative to the turntable; and A suspension assembly includes a ceiling-mounted component and a hanging rod, one end of which is connected to the drive component and the other end of which is connected to the ceiling-mounted component; The chassis and the turntable are provided with a reinforcing part, which is configured to fit against the chassis.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1 and Figure 2As shown, this invention discloses a fan light 100, which includes a lighting component, a fan component, and a suspension component. The lighting component includes a chassis 10, a light source module 11 integrated on the chassis 10, a drive module 12 electrically connected to the light source module 11, and a mask 13 fixedly connected to the chassis 10. The chassis 10 and the mask 13 together form a receiving cavity for accommodating the light source module 11 and the drive module 12. The mask 13 is configured to emit the emitted light from the light source module 11 to achieve a lighting effect. In this invention, the drive module 12 is preferably integrated on the chassis 10. Of course, the drive module 12 can also be set on the fan component or the suspension component according to the actual situation, as long as the drive module 12 can drive the lighting component and the fan component.

[0037] The fan assembly includes a turntable 20, a fan blade structure 21 disposed on the turntable 20 and operable to open or close relative to the turntable 20, and a drive member 22 connected to the turntable 20. The drive member 22 is configured to drive the turntable 20 to rotate, thereby causing the fan blade structure 21 to open or close relative to the turntable 20. The suspension assembly includes a ceiling mount 30 and a hanging rod 31. One end of the hanging rod 31 is connected to the drive member 22, and the other end is connected to the ceiling mount 30. The lighting assembly is disposed below the turntable 20 and is connected to the drive member 22. The hanging rod 31 is also connected to the drive member 22, allowing the lighting assembly to be stably suspended from the roof or other mounting surface.

[0038] Combination Figure 2 , Figure 3 as well as Figure 4 As shown, the cross-section of the fan light 100 of the present invention is circular, therefore its faceplate 13, base 10, and turntable 20 are also circular. The base 10 includes a main body 101 and a protrusion 102 surrounding the outer periphery of the main body 101. A positioning part 103 is provided on the inner sidewall of the protrusion 102. The faceplate 13 is provided with a corresponding mating part 131 that cooperates with the positioning part 103. The mating part 131 is configured to cooperate with the positioning part 103 so that the faceplate 13 and the base 10 are fixedly connected.

[0039] Preferably, the positioning part 103 is configured as a rib 103 protruding towards the center of the chassis 10, and the ribs 103 are evenly distributed on the inner sidewall of the protrusion 102. The mating part 131 is configured to be recessed from the outer sidewall of the mask 13 towards the center of the mask 13, thereby fixing the chassis 10 and the mask 13 by the ribs 103 protruding into the mating part 131. This configuration simplifies the assembly of the mask 13 and the chassis 10, making the installation of the fan light 100 more convenient.

[0040] like Figure 4 , Figure 5 , Figure 6 as well as Figure 7As shown, further, the mating part 131 is arranged around the edge of the face mask 13. The face mask 13 includes a first sidewall 1310, a second sidewall 1311 disposed opposite to the first sidewall 1310, and a connecting wall 1312 connecting the first sidewall 1310 and the second sidewall 1311. The mating part 131 is formed by the first sidewall 1310 and the connecting wall 1312. The first sidewall 1310 is received in the receiving cavity and abuts against the upper surface of the rib 103. The rib 103 extends into the mating part 131 and abuts against the connecting wall 1312. The second sidewall 1311 abuts against the protrusion 102. This arrangement can reduce the gap between the face mask 13 and the base 10, making it not only difficult to disassemble the base 10 and the face mask 13 after installation, but also preventing mosquitoes from entering the receiving cavity.

[0041] Furthermore, the chassis 10 is also provided with an abutment portion 104, which protrudes toward the face mask 13 and abuts against the inner wall of the connecting wall 1312. The rib 103 and the abutment portion 104 are staggered and press against the connecting wall 1312 in the inward and outward directions. In other words, by using the staggered rib 103 and the abutment portion 104, when assembling the chassis 10 and the face mask 13, the rib 103 and the abutment portion 104 can press against the connecting wall 1312 in the inward and outward directions, further ensuring that the face mask 13 is not easy to fall off the chassis 10. At the same time, it is convenient to assemble the chassis 10 and the face mask 13 on the basis of compression and fixation, and it is not easy to disassemble after assembly.

[0042] Of course, in order to make the connection between the chassis 10 and the mask 13 tighter, the connection between the positioning part 103 and the mating part 131 can be designed as a non-detachable connection. That is, the positioning part 103 and the mating part 131 are used to fix the chassis 10 and the mask 13 together. This not only ensures that the gap between the mask 13 and the chassis 10 is smaller, but also ensures the connection stability between the components in the lighting assembly. The connection stability between the mask 13 and the chassis 10 will not be affected by human or environmental factors. At the same time, it protects the internal structure of the housing cavity to prevent dust, insects and other pollutants from entering the housing cavity, damaging the luminous efficiency of the light source module 11, damaging the lighting assembly and affecting the service life of the fan light 100.

[0043] Combination Figure 2 , Figure 3 , Figure 8 as well as Figure 9As shown, a receiving groove 105 for housing the drive module 12 is recessed in the middle of the chassis 10 towards the turntable 20, and this receiving groove 105 communicates with the receiving cavity. The light source module 11 is arranged in a ring shape, and surrounds the receiving groove 105 and is tightly fixed to the chassis 10; the light source module 11 includes a ring-shaped light source plate 110 and LED light sources 111 evenly distributed on the light source plate 110. This arrangement not only effectively improves the space utilization within the receiving cavity, but also ensures that the drive module 12 does not obstruct the light source module 11.

[0044] Specifically, the drive module 12 includes a circuit board 120 and a cover plate 121 for protecting the circuit board 120. The entire circuit board 120 is placed in the receiving groove 105 and fixedly connected to the chassis 10. The circuit board 120 integrates multiple functional components for adjusting the brightness and temperature of the lighting components, etc. The cover plate 121 is assembled and fixed to the inner wall of the receiving groove 105 to cover and protect the circuit board 120. In this invention, the cover plate 121 is fixed to the inner wall of the receiving groove 105 by a snap-fit ​​connection, but this should not be a limitation, as long as it can achieve the purpose of removing the cover plate 121 from the chassis 10.

[0045] Furthermore, combined Figure 10 As shown, the drive module 12 also includes several wires. A first rack 1210 protrudes from the side of the cover plate 121 facing the circuit board 120. Correspondingly, a second rack 1210' is provided at the center of the chassis 10. When the cover plate 121 is snapped and fixed to the chassis 10, the first rack 1210 and the second rack 1210' are arranged vertically opposite each other, forming a locking space 1211 between the first rack 1210 and the second rack 1210'. The wires are locked in the locking space 1211 to prevent pulling during wire assembly or use. Preferably, the first rack 1210 is arranged in a ring and located at the center of the cover plate 121, and the second rack 1210' is also arranged in a ring and located at the center of the chassis 10. This allows multiple wires to be concentrated and locked between the first rack 1210 and the second rack 1210' to prevent wire pulling and also facilitates installation.

[0046] Furthermore, a flame-retardant pad 14 is provided between the chassis 10 and the circuit board 120 to prevent the drive module 12 from overheating. The two sides of the flame-retardant pad 14 are fixedly connected to the chassis 10 and the circuit board 120 respectively to prevent the circuit board 120 from spontaneously combusting due to excessive temperature during operation. Of course, if the chassis 10 already contains flame-retardant materials, then the flame-retardant pad 14 may not be provided between the chassis 10 and the circuit board 120. That is, whether or not the flame-retardant pad 14 is provided depends on the specific material of the chassis 10.

[0047] The drive unit 22 is electrically connected to the drive module 12, so that the drive module 12 can provide power to the drive unit 22 or the light source module 11 independently to start the lighting component or the fan component, or it can provide power to both the drive unit 22 and the light source module 11 simultaneously to start both the lighting component and the fan component. This effectively improves the space utilization of the receiving cavity and also effectively reduces the weight of the entire fan light 100. In this embodiment, the drive unit 22 is a DC motor; of course, in other embodiments, the drive unit 22 can also be an AC motor, as long as it can drive the turntable 20 to rotate, and there is no limitation here.

[0048] Combination Figure 2 and Figure 11 As shown, the driving component 22 in this invention is preferably an external rotor motor. This external rotor motor 22 includes a stator and a rotor surrounding the stator. The stator is fixedly connected to the chassis 10, and the rotor is fixedly connected to the turntable 20. Specifically, one end of the external rotor motor 22 is connected to the hanger 31, and the other end passes through both the turntable 20 and the chassis 10, and is fixedly connected to the chassis 10. With this configuration, the turntable 20 can rotate relative to the chassis 10 under the drive of the rotor, causing the fan blade structure 21 on the turntable 20 to unfold or retract. Of course, the driving component 22 can also be a driving component of other structures, as long as it can drive the turntable 20 to rotate relative to the chassis 10; no further restrictions are placed. Furthermore, the external rotor motor 22 in this invention is smaller and thinner than traditional motors. This configuration makes the fan light 100 look more aesthetically pleasing when viewed from a 45° angle.

[0049] The fan light 100 of the present invention also includes a temperature sensor 23 for detecting the ambient temperature around the fan light 100. The temperature sensor 23 is fixedly connected to the drive component 22 and is located at one end of the drive component 22 near the hanging rod 31. Preferably, the temperature sensor 23 is a temperature sensor with intelligent control function, used to detect the ambient temperature around the fan light 100 in real time, and control the rotation speed of the fan blade structure 21 in real time according to the current ambient temperature. For example, when the ambient temperature rises, the rotation speed of the fan blade structure 21 increases, and when the ambient temperature falls, the rotation speed of the fan blade structure 21 decreases, thereby achieving the purpose of intelligent control.

[0050] A protective cover 24 is fitted onto the temperature sensor 23. The protective cover 24 is hollow and fixedly connected to the drive component 22 to protect the temperature sensor 23. Of course, the temperature sensor 23 of the present invention can also be set in other locations, as long as it can detect the temperature of the environment around the fan light 100 in real time, and no further restrictions are imposed.

[0051] Combination Figure 2 and Figure 12As shown, a reinforcing part 15 is provided between the chassis 10 and the turntable 20. The reinforcing part 15 is configured to fit against the chassis 10, and the reinforcing part 15 has a fixing part 152, which passes through the chassis 10 and is fixedly connected to the chassis 10.

[0052] Specifically, such as Figure 12 , Figure 13 as well as Figure 14 As shown, the reinforcing part 15 is located in the middle of the chassis 10. A first groove 106 with an opening facing the turntable 20 is provided on the side of the chassis 10 near the turntable 20. The reinforcing part 15 is placed inside the first groove 106 and fits against the side wall of the first groove 106. A second groove 107 is recessed in the middle of the first groove 106. A protrusion 150 corresponding to the second groove 107 is provided in the middle of the reinforcing part 15, fitting snugly inside the second groove 107. A through hole 151 is formed at the center of the protrusion 150. A corresponding through hole 108 is formed on the chassis 10. A fixing part 152 is formed by tearing on the protrusion 150. Part of the fixing part 152 is located at the edge of the through hole 151, and another part surrounds the side of the through hole 151. These fixing parts 152 all protrude towards the chassis 10 to pass through the through hole 108 and be fixedly connected to the chassis 10.

[0053] A groove 153 opposite to the protrusion 150 is formed on the reinforcing part 15. That is, when the groove 153 is formed by pressing on the reinforcing part 15, the other side of the reinforcing part 15 protrudes outward simultaneously, thus forming the protrusion 150. The driving member 22 passes through the through hole 151 and the through hole 108 in sequence and abuts against the inner wall of the groove 153. With this arrangement, the reinforcing part 15 not only strengthens the structural strength of the chassis 10 to prevent damage to the chassis 10 when the fan assembly rotates, but also can cooperate and connect with the chassis 10 and the turntable 20 to increase the heat dissipation area between the chassis 10 and the turntable 20.

[0054] To further enhance the structural strength of the chassis 10, a raised rib 154 is formed on the side of the reinforcing part 15 facing the turntable 20. The raised rib 154 is evenly distributed on the reinforcing part 15 and connects the outer wall of the groove 153 to the outer edge of the reinforcing part 15. Furthermore, the reinforcing part 15 is provided with positioning holes 155, and the chassis 10 is provided with corresponding positioning ribs 109 that mate with the positioning holes 155. During assembly, the positioning ribs 109 extend into the positioning holes 155, serving not only as pre-installation but also limiting the shaking between the reinforcing part 15 and the chassis 10. Multiple positioning holes 155 are provided, mainly including round holes and oblong holes 1550. The oblong holes 1550 are primarily designed to prevent tolerance issues during assembly of the reinforcing part 15 and the chassis 10, thereby facilitating assembly between the reinforcing part 15 and the chassis 10.

[0055] Combination Figure 2 , Figure 6 , Figure 11 as well as Figure 12 As shown, an annular groove 10A is formed near the edge of the chassis 10, with the opening of the annular groove 10A facing the turntable 20. The turntable 20 has a protruding edge 201 at its edge. After the chassis 10 and the turntable 20 are assembled, the protruding edge 201 is received in the annular groove 10A. Specifically, the annular groove 10A is formed between the body portion 101 and the protrusion 102 of the chassis 10, and the bottom of the annular groove 10A is configured to abut against the second sidewall 1311 of the face mask 13. In this invention, the turntable 20 and the base 10 are stacked vertically. The drive component 22 passes through both the turntable 20 and the base 10, fixing the rotor to the turntable 20 and the stator to the base 10. The turntable 20 has a raised edge 201 at its edge, which is housed within an annular groove 10A. This design improves the aesthetics of the assembly between the turntable 20 and the base 10, allows the raised edge 201 to rotate within the annular groove 10A, effectively controlling rotational errors, and also uses the base 10 to shield the turntable 20 from rotation. Thus, the turntable 20, drive component 22, and base 10 can be integrated into a single unit, combining the fan assembly and the lighting assembly. Under the drive of the drive component 22, the turntable 20 can rotate relative to the base 10, thereby causing the fan blade structure 21 to unfold or retract.

[0056] Combination Figure 1 , Figure 2 as well as Figure 15 As shown, the fan assembly includes three fan blade structures 21, which are evenly distributed on the turntable 20 and rotatably connected to it. A gap is formed between the preceding and following fan blade structures 21. Each fan blade structure 21 includes a leading edge 210 for air inflow, a trailing edge 211 for air outflow, and an arc surface 212 connecting the leading edge 210 and the trailing edge 211. The arc surface 212 curves downward from the leading edge 210 to the trailing edge 211 so that it can drive airflow when the fan blade structure 21 rotates. That is, air flows in from the leading edge 210 and contacts the arc surface 212, and then flows out from the trailing edge 211, thereby achieving a blowing effect.

[0057] Combination Figure 15 and Figure 16 Specifically, in this embodiment of the invention, the fan blade structure 21 further includes a side edge 213 connecting the leading edge 210 and the trailing edge 211, wherein the leading edge 210, the trailing edge 211, and the side edge 213 are all curved edges. When the fan blade structure 21 rotates, the inner leading edge 210 first contacts the airflow, and then the airflow flows from the leading edge 210 to the outer trailing edge 211 until it leaves the fan blade structure 21.

[0058] The end of the fan blade structure 21 near the side edge 213 is defined as the fan blade tip 21a, and the end of the fan blade structure 21 away from the side edge 213 is defined as the fan blade root 21b. The fan blade structure 21 includes a leading edge 210, a trailing edge 211, a side edge 213, and an arc surface 212. The side edge 213 connects the leading edge 210 and the trailing edge 211 and is located at the fan blade tip 21a. The leading edge 210, the trailing edge 211, and the side edge 213 are seamlessly connected and form the outer peripheral edge of the arc surface 212. In other words, the leading edge 210 and the trailing edge 211 are located on both sides of the width direction of the fan blade structure 21, and the arc surface 212 connects the leading edge 210 and the trailing edge 211.

[0059] Preferably, the leading edge 210 is in a concave arc shape, and the trailing edge 211 and the side edge 213 are both in a convex arc shape. In other words, the leading edge 210 and the trailing edge 211 each convex towards the leeward side, so that the two ends of the fan blade structure 21 in its length direction are located on the front side, and the middle area is located on the rear side. With this configuration, when the fan blade structure 21 rotates at high speed, the fan blade structure 21 can withstand the violent impact from the airflow and is not easy to deform or bend, thereby improving the overall strength and stability of the fan blade structure 21 and thus extending the service life of the fan blade structure 21.

[0060] Overall, the horizontal heights of both the leading edge 210 and the trailing edge 211 gradually increase from the blade root 21b towards the blade tip 21a, with the trailing edge 211 being lower than the leading edge 210. This causes the curved surface 212 to smoothly curve downwards from the leading edge 210 to the trailing edge 211, resulting in a blade structure 21 with a higher windward side and a lower leeward side. Thus, when the blade structure 21 rotates at high speed, the airflow enters the blade structure 21 from the leading edge 210, is guided by the curved surface 212, and exits the blade structure 21 through the trailing edge 211, thereby changing the airflow direction, improving the catching effect, and ultimately enhancing the blowing effect of the blade structure 21.

[0061] Furthermore, the leading edge 210 extends smoothly and gradually upwards from the blade root 21b toward the blade tip 21a, meaning that the two ends of the leading edge 210 along its length are not on the same horizontal plane. The structural design of the trailing edge 211 is the same as that of the leading edge 210. This makes the height of the entire blade root 21b lower than the height of the blade tip 21a. On the one hand, this effectively improves the direction of airflow, thereby achieving a better blowing effect. On the other hand, during the retraction of the blade structure 21, adjacent blade structures 21 are staggered and do not overlap when viewed from above, meaning that the orthographic projections of adjacent blade structures 21 on the horizontal plane do not overlap. The side of the trailing edge 211 of the preceding fan blade structure 21 near the end 21a of the fan blade is opposite to the side of the leading edge 210 of the following fan blade structure 21 near the root 21b of the fan blade. That is, the end 21a of the preceding fan blade structure 21 is located on the inner side of the front edge of the root 21b of the adjacent following fan blade structure 21, and there is a gap between them, so that the fan blade structure 21 can freely extend, retract and rotate, and it is also conducive to the miniaturization of the fan light 100 product.

[0062] The highest point of the fan blade structure 21 is located at the leading edge 210 near the end 21a of the fan blade, and the lowest point of the fan blade structure 21 is located at the trailing edge 211 near the root 21b of the fan blade. The distance between the highest point of the fan blade structure 21 and the root 21b accounts for 60% to 80% of the total length of the fan blade structure 21, preferably three-quarters. The height of the highest point of the fan blade structure 21 relative to the horizontal plane where the root 21b is located ranges from 40mm to 100mm, preferably 80mm. Furthermore, the horizontal plane where the lowest point of the fan blade structure 21 is located is flush with the horizontal plane where the root 21b is located. This improves the airflow efficiency of the fan blade structure 21, thereby increasing the air volume.

[0063] In addition, during the actual operation of the fan blade structure 21, the linear velocity at the fan blade root 21b is relatively high, while the linear velocity at the fan blade tip 21a is relatively low. In some embodiments, the fan blade structure 21 is gradually widened from the fan blade root 21b to the fan blade tip 21a. On the one hand, this can improve the overall strength and stability of the fan blade structure 21, enabling it to withstand greater centrifugal forces without deformation or damage, thus ensuring its normal operation. On the other hand, it can, to a certain extent, allow more air to flow with the fan blade structure 21 at a greater speed, thereby increasing the wind power of the fan blade structure 21. In other embodiments, the width of the fan blade structure 21 can be set to a constant value in the direction from the fan blade root 21b to the fan blade tip 21a, i.e., the distance from the leading edge 210 to the trailing edge 211 remains unchanged.

[0064] The radius of curvature of the leading edge 210 gradually increases from the blade root 21b to the blade tip 21a, while the radius of curvature of the trailing edge 211 exhibits a regular trend of first gradually increasing and then gradually decreasing, thus maintaining the curved shape of the trailing edge 211. The side edge 213 has a flow guiding function, which can reduce the airflow resistance of the blade structure 21, thereby reducing energy consumption and noise. The side edge 213 has a first end connected to the leading edge 210 and a second end connected to the trailing edge 211, wherein the radius of curvature of the side edge 213 first decreases and then increases from the first end to the second end. In summary, the changing trend of the radii of curvature of the leading edge 210 and the side edge 213 enables the blade structure 21 to reduce the airflow impact it receives during operation, thereby improving its overall strength.

[0065] Please see Figure 17 As shown, specifically, the leading edge 210 includes a first arc segment 2100 near the blade root 21b and a second arc segment 2101 connected to the side edge 213. The radius of curvature of the first arc segment 2100 is smaller than the radius of curvature of the second arc segment 2101. The radius of curvature of the leading edge 210 is between 100 mm and 110 mm. Preferably, the radii of curvature of the first arc segment 2100 and the second arc segment 2101 are 107.7 mm and 109.0 mm, respectively. The radius of curvature of the trailing edge 211 maintains its curved shape. The trailing edge 211 includes a third arc segment 2110, a fourth arc segment 2111, a fifth arc segment 2112, a sixth arc segment 2113, a seventh arc segment 2114, and an eighth arc segment 2115 extending from the blade root 21b toward the blade tip 21a. The radius of curvature of the trailing edge 211 exhibits a cyclical trend of first increasing and then decreasing from the third arc segment 2110 to the seventh arc segment 2114. The radius of curvature of the trailing edge 211 is between 85mm and 190mm. In some embodiments, the radius of curvature of the trailing edge 211 ranges from 90.7 mm to 185.2 mm. Preferably, the radii of curvature of the third arc segment 2110, the fourth arc segment 2111, the fifth arc segment 2112, the sixth arc segment 2113, the seventh arc segment 2114, and the eighth arc segment 2115 are 94.5 mm, 185.2 mm, 90.7 mm, 174.2 mm, 113.8 mm, and 181.1 mm, respectively.

[0066] The side edge 213 has a flow guiding function, which can reduce the air resistance of the fan blade structure 21, thereby reducing energy consumption and noise. The side edge 213 has a first end connected to the leading edge 210 and a second end connected to the trailing edge 211. The radius of curvature of the side edge 213 first decreases and then increases from the first end to the second end, making the side edge 213 a relatively smooth arc structure, which can improve the overall strength and stability of the fan blade structure 21. Specifically, the side edge 213 includes a ninth arc segment 2130, a tenth arc segment 2131, an eleventh arc segment 2132 and a twelfth arc segment 2133 that are connected to each other. The first end of the side edge 213 is located at the ninth arc segment 2130, and the second end of the side edge 213 is located at the twelfth arc segment 2133. The radius of curvature of the side edge 213 gradually decreases from the ninth arc segment 2130 to the tenth arc segment 2131, and gradually increases from the tenth arc segment 2131 to the twelfth arc segment 2133. The radius of curvature of the side edge 213 is between 30 mm and 100 mm. Preferably, the radius of curvature of the side edge 213 is between 30.6 mm and 97.6 mm. The radius of curvature of the ninth arc segment 2130 is smaller than that of the twelfth arc segment 2133. The radii of curvature of the ninth arc segment 2130 and the twelfth arc segment 2133 are 72.2 mm and 97.6 mm, respectively.

[0067] Preferably, the average radius of curvature of the leading edge 210 is smaller than that of the trailing edge 211, but larger than that of the side edge 213, which can improve the overall strength and stability of the fan blade structure 21. By setting the radii of curvature of the leading edge 210, trailing edge 211, and side edge 213, the wind-catching effect of the fan blade structure 21 is improved, thereby increasing the air volume.

[0068] like Figure 18As shown, specifically, in the width direction of the arc surface 212, the arc surface 212 includes a first cross-section, a second cross-section, and a third cross-section (corresponding to the cross-sections at the first dashed line A, the second dashed line B, and the third dashed line C, respectively) provided from the blade root 21b towards the blade tip 21a. That is, the first cross-section, the second cross-section, and the third cross-section are all cross-sections of the arc surface 212 along its width direction. Overall, the lateral radius of curvature of the cross-section of the arc surface 212 gradually increases and then gradually decreases from the leading edge 210 towards the trailing edge 211. In other words, the lateral curvature of the arc surface 212 gradually decreases and then gradually increases from the leading edge 210 towards the trailing edge 211, thus achieving a good catching effect. The longitudinal radius of curvature of the arc surface 212 gradually decreases and then remains essentially constant from the blade root 21b towards the blade tip 21a. In other words, the longitudinal curvature of the arc surface 212 gradually increases and then remains essentially constant from the blade root 21b towards the blade tip 21a. Thus, on the one hand, the application of the fan blade structure 21 in the fan light 100 product can reduce wind resistance and thus achieve a better blowing effect; on the other hand, it can also improve the overall strength of the fan blade structure 21.

[0069] The thickness of the fan blade structure 21 gradually decreases from the root 21b to the tip 21a, meaning the root 21b is thicker and the tip 21a is thinner, creating a gradual transition in overall thickness. This enhances the overall strength and stability of the fan blade structure 21, preventing deformation or bending during high-speed rotation and ensuring its normal operation. The thickness of both the leading edge 210 and the trailing edge 211 gradually decreases from the root 21b towards the tip 21a, forming a gradually curved structure. Furthermore, in the width direction of the arc surface 212, the thickness of the leading edge 210 is less than that of the arc surface 212, resulting in a wider and gentler airflow area, providing a more comfortable experience and achieving excellent wind-cutting performance.

[0070] Furthermore, the fan blade structure 21 also includes a connector 214, which is foldable or unfoldable and disposed on the periphery of the turntable 20, thereby improving the overall strength and airflow effect of the fan light 100. The connector 214 is fixedly connected to the side of the fan blade root 21b away from the fan blade tip 21a, and the fan blade structure 21 is connected to the turntable 20 through the connector 214. Specifically, the connector 214 is disposed between the leading edge 210 and the trailing edge 211, and protrudes from the fan blade root 21b to facilitate its connection with the turntable 20. In some embodiments, the connector 214 is assembled with the arc surface 212 to form a whole; in other embodiments, it may also be manufactured using a one-piece molding process.

[0071] The number of fan blade structures 21 is preferably three. When all three fan blade structures 21 are closed, the side of the leading edge 210 of the preceding fan blade structure 21 near the root 21b of the fan blade is opposite to the side of the trailing edge 211 of the following fan blade structure 21 near the end 21a of the fan blade, and a gap is formed between the preceding fan blade structure 21 and the following fan blade structure 21, so that the three fan blade structures 21 do not overlap with each other.

[0072] like Figure 16 As shown, to further improve the overall strength of the fan blade structure 21, a first reinforcing rib 215 and a second reinforcing rib 216 are also provided on the fan blade structure 21. The first reinforcing rib 215 is located along the length of the fan blade structure 21 near the turntable 20, extending from the fan blade root 21b towards the fan blade tip 21a. The width of the first reinforcing rib 215 gradually decreases, forming a fishbone-like structure. Preferably, the first reinforcing rib 215 is located in the middle region of the arc surface 212 in the width direction. Of course, the specific location and cross-sectional shape of the first reinforcing rib 215 can be further defined according to specific needs, and this invention does not limit this.

[0073] The second reinforcing rib 216 is disposed between the connector 214 and the blade root 21b. The connector 214 is fixedly connected to the blade root 21b through the second reinforcing rib 216 to strengthen the connection between the two. Optionally, there may be multiple second reinforcing ribs 216, which are arranged in a ring at equal intervals between the connector 214 and the blade root 21b. The specific number of second reinforcing ribs 216 can be set according to the actual size of the blade structure 21, and the present invention does not limit this.

[0074] The present invention will now use two sample test structures to illustrate the air blowing effect of the fan blade structure 21 of the present invention.

[0075] Test results Two identical fan light products 100, with rotational speed as the sole variable, were designated as Sample 1 and Sample 2. In this embodiment of the invention, Sample 1 had a rotational speed of 260 rpm, and Sample 2 had a rotational speed of 270 rpm. Multiple measurement points were defined, and various performance data of Sample 1 and Sample 2, such as test voltage, input power, and energy efficiency value, were tested when they were started. The test results are shown in Table 1. The air blowing effect of Sample 1 and Sample 2 was compared by testing the wind speed at different measurement points, and the test results are shown in Tables 2 and 3, respectively.

[0076] Table 1. Performance data of Sample 1 and Sample 2 during operation. As shown in Table 1, under otherwise identical conditions, the total air volume of Sample 1 is slightly lower than that of Sample 2 because the rotation speed of Sample 1 is lower. This indicates that the total air volume is related to the rotation speed of the fan lamp 100; as the rotation speed increases, the total air volume also increases. However, the energy efficiency value of Sample 1 is slightly higher than that of Sample 2, indicating that Sample 1 is more energy-efficient than Sample 2.

[0077] Table 2. Test results of wind speed at different measurement points for Sample 1 Table 3 Wind speed measurement results of Sample 2 at different measurement points Define the side of the test point closest to the fan light 100 as the front side of the test point, and take the center point of the fan light 100 as the center and the distance between the test point and the central axis of the fan light 100 as the radius of the ring, thus forming a ring.

[0078] As shown in Tables 2 and 3, the wind speeds measured at different test points varied. Specifically, overall, the wind speeds at the test points (including those in front, behind, to the left, and to the right of the test point) initially showed a positive correlation with the distance from the test point to the central axis of the fan light 100, followed by a negative correlation. Furthermore, the direction of the maximum wind speed at the test point varied irregularly at different circular radii, which may be related to factors such as airflow in the actual test environment.

[0079] Furthermore, when the radius of the ring is 200 meters, the average wind speeds of both Sample 1 and Sample 2 reach their maximum values, at 164.34 m / min and 164.87 m / min respectively, with very little difference between them. This may be due to the larger test distance and the influence of actual airflow factors. When the radius of the ring is 360 meters, the airflow through the ring for both Sample 1 and Sample 2 reaches its maximum values, at 21.66 m³ / min and 22.66 m³ / min respectively. This indicates that the fan light 100 has the best blowing effect at a test point 200 meters from its central axis, while the fan light 100 has the highest airflow through the ring at a test point 360 meters from its central axis. It can be seen that although the rotational speed of sample 1 is lower than that of sample 2, the average wind speed and the air volume passing through the ring of sample 1 and sample 2 are only slightly different. In other words, the fan blade structure 21 of the present invention has a better blowing effect due to the improvement of its radius of curvature when the rotational speed changes, and will not be greatly affected by the change in rotational speed.

[0080] At a circular radius of 40 meters, the average wind speed and airflow through the circular ring of sample 1 were significantly lower than those of sample 2. This is likely due to the closer distance between the test point and the central axis of the fan light 100, making wind speed the primary influencing factor. Overall, when the circular radius is between 40 and 200 meters, the average wind speed and airflow through the circular ring of the fan light 100 increase with increasing radius. When the circular radius is between 200 and 920 meters, the average wind speed of the fan light 100 decreases with increasing radius, while the airflow through the circular ring of the fan light 100 first increases and then decreases with increasing radius. When the circular radius exceeds 1000 meters, no average wind speed or airflow was measured at the test point for either sample 1 or sample 2. This is because the flowing air is continuously affected by resistance during its flow, causing the wind force to gradually weaken and eventually reach zero. At a radius of 920 meters, the average wind speed of sample 2 was higher than that of sample 1. This indicates that at this location, the average wind speed is related to the higher rotational speed of sample 2 compared to sample 1, while the influence of airflow in the test environment is relatively small. As mentioned earlier, the fan light 100 product provided by this invention can achieve wide-range airflow and can be applied in large-area locations such as workshops and warehouses that require cooling.

[0081] It should be noted that, in addition to the above-mentioned structures, the suspension assembly and fan blade structure 21 can also be configured with other features by referring to existing technical solutions, and there are no restrictions on the specific structure of the suspension assembly and fan blade structure 21.

[0082] In summary, the fan light 100 of the present invention strengthens the structural strength of the chassis 10 by providing a reinforcing part 15 between the chassis 10 and the turntable 20. When the turntable 20 rotates at high speed under the drive of the drive member 22, the chassis 10 can remain stable and better protect the lighting components. In addition, the mating connection between the chassis 10 and the mask 13 allows the mask 13 to be better fixedly connected to the chassis 10 and is not easy to detach from the chassis 10.

[0083] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
