The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] like Figure 1 As shown, the present invention discloses a lighting fixture 10 with healthy light, including: a base 20, a light source 30, and a fan assembly 40.

[0040] The light source 30 and the fan assembly 40 are mounted on the base 20.

[0041] like Figure 2 As shown, the fan assembly 40 includes a turntable 100 and a plurality of fan blades 200. The turntable 100 is rotatably mounted on the base 20. Each fan blade 200 is rotatably positioned at the edge of the turntable 100 via an angle adjustment member 300. The plurality of fan blades 200 are arranged in a circular array around the rotation axis of the turntable 100. The fan assembly 40 also includes a driver (not shown) that is drivenly connected to the turntable 100. In this embodiment, the driver is a motor.

[0042] like Figure 1 and Figure 2 As shown, the axis of rotation of turntable 100 is perpendicular to the horizontal plane, and the axis of rotation of fan blade 200 is parallel to the horizontal plane.

[0043] like Figure 1 and Figure 2 As shown, the light source 30 is located at the center of the area enclosed by multiple fan blades 200.

[0044] Each blade 200 is rotatably positioned on the edge of the turntable 100 via the angle adjustment component 300. This can be understood as follows:

[0045] like Figure 1 As shown, the fan blades 200 can be adjusted to be parallel to the horizontal plane by the angle adjustment component 300. At this time, the multiple fan blades 200 are in a divergent state. When the multiple fan blades 200 are in a divergent state, the light source 30 is not blocked by the multiple fan blades 200, and the light emitted by the light source 30 can illuminate a larger area to achieve the purpose of large-area lighting.

[0046] like Figure 2As shown, the fan blades 200 can be adjusted to be perpendicular to the horizontal plane by the angle adjustment component 300. At this time, the multiple fan blades 200 are in a converged state. When the multiple fan blades 200 are in a converged state, the light source 30 is blocked by the multiple fan blades 200. The light emitted by the light source 30 can only shine out through the opening formed by the multiple fan blades 200, achieving the effect of small-area focused lighting, similar to a downlight.

[0047] In this invention, the fan blades 200 are made of an opaque material, so that when multiple fan blades 200 are clustered together, the light emitted by the light source 30 will not pass through the panel. Preferably, the fan blades 200 are made of wood. Of course, the fan blades 200 can also be made of plastic.

[0048] like Figure 2 and Figure 3 As shown, in this invention, the fan blade 200 has a windward side 210 and a blocking side 220. When multiple fan blades 200 are in a converged state, the windward side 210 of one fan blade 200 presses against the blocking side 220 of another adjacent fan blade 200. When multiple fan blades 200 change from a converged state to a divergent state, the fan blades 200 rotate with the turntable 100, and their windward side 210 can face the wind to achieve the overall lifting of the fan blade 200.

[0049] The lighting fixture 10 with healthy light of the present invention has a light source 30 comprising: visible light LED, ultraviolet LED, and infrared LED. The spectral range of the light source 30 is from ultraviolet light to infrared light. This lighting source not only has ordinary lighting function, but also ultraviolet sterilization function and infrared health care function.

[0050] For example, the remote control used to control the light source 30 has three buttons: general lighting, ultraviolet sterilization, and infrared health care. When the general lighting button is pressed, the visible light LED lights up, thus realizing the function of general lighting; when the ultraviolet sterilization button is pressed, the ultraviolet LED lights up, thus realizing the function of ultraviolet sterilization; when the infrared LED button is pressed, the infrared LED lights up, thus realizing the function of infrared health care.

[0051] The present invention also aims to solve the following technical problem:

[0052] The lighting fixture is suspended from the ceiling at a certain height from the ground. One method to adjust the angle of the fan blades 200 is to install an angle adjustment controller on the lighting fixture, which then drives the fan blades 200 to adjust their angle. However, adding an additional angle adjustment controller significantly increases production costs.

[0053] Therefore, how to optimize the structure of the angle adjustment component 300, and use the rotation of the fan blade 200 itself to achieve angle adjustment through the start-stop driver, so that multiple fan blades 200 can switch between divergent and convergent states, is a technical problem that needs to be solved.

[0054] Please refer to the following: Figure 3 , Figure 4 , Figure 5 and Figure 6 Specifically, the angle adjustment component 300 includes: a fixed base 400, a shaft 500, and a sleeve 600.

[0055] The fixed base 400 has a receiving cavity 410 (e.g. Figure 4 As shown, the shaft 500 is inserted into the fixed base 400 and partially located in the receiving cavity 410. In this embodiment, the shaft 500 is a bolt structure.

[0056] The sleeve 600 is rotatably fitted onto the shaft 500, and the fan blade 200 is connected to the outer wall of the sleeve 600.

[0057] like Figure 4 and Figure 6 As shown, an angle adjustment groove 610 is provided on the end face of the sleeve 600, and an angle adjustment block 700 that cooperates with the angle adjustment groove 610 is rotatably provided on the cavity wall of the accommodating cavity 410.

[0058] Please refer to the following: Figure 7 , Figure 8 and Figure 9 The angle adjustment groove 610 has a first blocking surface 611 and a second blocking surface 612 located at both ends of the groove body. The angle adjustment groove 610 is provided with a middle stop head 613 and an end stop head 614. The middle stop head 613 is located in the middle of the angle adjustment groove 610, and the end stop head 614 is located close to the first blocking surface 611.

[0059] like Figure 9 As shown, the angle adjustment block 700 has a first end face 710 and a second end face 720 located at both ends of the block body. A first slot 711 is provided on the first end face 710, and a second slot 721 is provided on the second end face 721.

[0060] The working principle of the above-mentioned lighting fixture 10 with healthy light will be explained below, taking into account the specific structure of the angle adjustment component 300:

[0061] Let the initial state be when multiple fan blades 200 are in a divergent state (e.g.) Figure 1As shown), the driver is not started at this time, the turntable 100 does not rotate, and the multiple fan blades 200 do not rotate (i.e., the fan assembly 40 is in a non-working state). The light source 30 is not blocked by the multiple fan blades 200, and the light emitted by the light source 30 can illuminate a larger area, achieving the purpose of large-area lighting; as shown Figure 10 As indicated by reference numeral 1, in this state, the intermediate stop head 613 is pressed into the first slot 711 of the angle adjustment block 700 to form a stable support;

[0062] When the driver is started, the turntable 100 rotates, and the multiple fan blades 200 also rotate (i.e., the fan assembly 40 is in working condition). At this time, the multiple fan blades 200 are still in a divergent state, and the light source 30 is not blocked by the multiple fan blades 200. The light emitted by the light source 30 can illuminate a wider area; such as Figure 10 As shown in reference numeral 2, during this process, the fan blade 200 generates a lifting force as it rotates with the turntable 100. This lifting force causes the sleeve 600 to rotate around the shaft 500. When the sleeve 600 rotates, the end stop 614 contacts the second end face 720 and pushes the angle adjusting block 700 to rotate (the first slot 711 separates from the middle stop 613); as Figure 10 As indicated by reference numeral 3, the sleeve 600 continues to rotate until the first end face 710 contacts the first blocking surface 611, at which point the sleeve 600 stops rotating and remains in this state; it can be understood that as long as the fan assembly 40 is in operation, the first end face 710 and the first blocking surface 611 will remain in contact.

[0063] When the driver is turned off, the turntable 100 stops rotating, and the multiple fan blades 200 also stop rotating (i.e., the fan assembly 40 is in working condition). Under the influence of gravity, the fan blades 200 will fall (i.e., the sleeve 600 rotates in the opposite direction around the shaft 500), and the multiple fan blades 200 will be in a converged state. The light source 30 is blocked by the multiple fan blades 200, and the light emitted by the light source 30 can only shine out through the opening formed by the multiple fan blades 200, achieving the effect of small-area focused lighting; such as Figure 10 As indicated by reference numeral 4, during this process, the sleeve 600 rotates in the opposite direction around the shaft 500, and the intermediate stop head 613 contacts the angle adjusting block 700 (the first end face 710 separates from the first blocking surface 611). The intermediate stop head 613 causes the angle adjusting block 700 to rotate a small angle to adjust to a suitable posture; as shown in Figure 4. Figure 10 As shown in reference numeral 5, the sleeve 600 continues to rotate in the opposite direction around the shaft 500, and the second end face 720 of the angle adjusting block 700, which has been adjusted to a suitable posture, will abut against the second blocking surface 612; after the second end face 720 abuts against the second blocking surface 612, the sleeve 600 rotates in the opposite direction around the shaft 500 to the position.

[0064] Restarting the driver causes the turntable 100 to rotate, and the multiple fan blades 200 also rotate (i.e., the fan assembly 40 is in operation). As the fan blades 200 rotate with the turntable 100, they generate a lifting force. This lifting force causes the sleeve 600 to rotate forward around the shaft 500 (separating the second end face 720 from the second blocking surface 612). Figure 10 As indicated by reference numeral 6, during rotation, the end stop 614 will be engaged in the first slot 711 (the angle adjustment block 700 rotates slightly during engagement, which prepares for the subsequent engagement of the intermediate stop 613 in the second slot 721); it is worth noting that in this state, the end stop 614 is engaged in the first slot 711 (the end stop 614 is not abutting against the first end face 710), and the angle adjustment block 700 will be locked after only a slight rotation and will not be able to continue rotating;

[0065] Next, the drive is turned off, the turntable 100 stops rotating, and the multiple fan blades 200 also stop rotating (i.e., the fan assembly 40 is in the working state). Under the influence of gravity, the fan blades 200 will fall (i.e., the sleeve 600 rotates in the opposite direction around the shaft 500). It is worth noting that at this time, the multiple fan blades 200 will not be in a convergent state, as... Figure 10 As indicated by reference numeral 1, this is because the intermediate stop head 613 is stuck in the second slot 721 (which can also be regarded as the first slot 711), and is blocked by the angle adjustment block 700, so the multiple fan blades 200 still remain in a divergent state; it should also be noted that when the intermediate stop head 613 is stuck in the second slot 721, the angle adjustment block 700 rotates slightly, which prepares for the subsequent end stop head 614 to touch the end face of the angle adjustment block 700 and push it to rotate;

[0066] Restart the drive; turntable 100 rotates, and multiple fan blades 200 also rotate (i.e., fan assembly 40 is in operation). Figure 10 As shown in reference numeral 2, the end stop head 614 will contact the first end face 710 (which can also be regarded as the second end face 720) and push the angle adjustment block 700 to rotate;

[0067] This cycle repeats itself.

[0068] As can be seen from the above explanation of the working principle of the lighting fixture 10 with healthy light, simply starting and stopping the driver can switch the multiple fan blades 200 between a diverging state and a converging state. Of course, if the driver of this lighting fixture 10 with healthy light is always on (equivalent to realizing a blowing function), the multiple fan blades 200 can only exhibit a diverging state.

[0069] In this invention, angle adjustment grooves 610 are provided on both end faces of the sleeve 600, and two angle adjustment blocks 700 are provided, each corresponding to an angle adjustment groove 610 on one end face of the sleeve 600. This structural design can better improve the stability of the fan assembly 40 during the angle adjustment and positioning process.

[0070] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
