The light source assembly 3 is disposed between the blade 2 and the fan main body 1. The fan body 1 is configured to rotate the blades 2, thereby performing a fan function of the fan lamp 100, in addition to serving as a mounting base for some structural members. In this application, blade 2 both had accomplished rotation blowing function as the flabellum, still accomplished the illumination function as leaded light blade. Therefore, the fan lamp 100 of the present invention not only has both the functions of fan and illumination, but also has a reduced number of parts compared to the conventional fan lamp.

Compared with the case that the accommodating member 12 is completely protruded from the chassis 111, in the embodiment, the overlapping portion of the chassis 111 and the accommodating member 12 can provide a certain supporting effect for the accommodating member 12, thereby improving the reliability of the fan lamp 100. On the other hand, the chassis 111 also has a certain shielding effect on the receptacle 12, and improves the appearance of the fan lamp 100.

In order to provide the illumination function, the blade 2 is made of a transparent material so as to guide light. Therefore, in the present application, the vane 2 may also be referred to as a light guide vane. Preferably, the light guide blade is made of one of polycarbonate and polymethacrylate, and both the polycarbonate and the polymethacrylate have high transparency and can achieve a good light emitting effect. In other embodiments, the light guide vane may be made of PP (polypropylene) or ABS (acrylonitrile-butadiene-styrene terpolymer). However, PP or ABS has poorer light transmittance than polycarbonate and polymethacrylate.

Referring to fig. 7, the blade 2 has both functions of fan and illumination, and includes a blade main body 21 and a blade root 22, the blade main body 21 is used for providing illumination and fan functions, and the blade root 22 is disposed close to the fan main body 1 relative to the blade main body 21 and is used for fixedly connecting the blade main body 21 to the fan main body 1. The blade 2 includes a light incident surface 221 and a light emergent surface, the light incident surface 221 is disposed at one end of the blade 2 close to the fan main body 1 and is located in the light emergent direction of the light source assembly 3, and the light emergent surface is formed along the length direction of the blade 2 to provide space illumination. The plane of the light incident surface 221 intersects with the plane of the light emitting surface, and the light incident surface 221 is formed along the thickness direction of the blade 2. Preferably, the long side of the light incident surface 221 is smaller than or equal to the long side of the blade root 22 and is equal to the width of the blade body 21.

The blade body 21 is provided with a light emitting structure 211, and the light emitting structure 211 is used for emitting light, so that an illumination effect is formed. The light exit structure 211 may be provided integrally with the blade body 21 or may be provided separately from the blade body 21. The light exit structure 211 is disposed on the blade body 21 in a length direction of the blade body 21. Preferably, the light exiting structure 211 is located on the upper surface of the blade body 21, and the light exiting surface is located below the light exiting structure 211, that is, the light exiting surface is located on the lower surface of the blade body 21. In the present application, the upper surface is a surface of the blade body 21 facing the mounting wall, and the lower surface is a surface of the blade body 21 facing the illumination space, i.e., near the user.

Referring to fig. 1, fig. 2 and fig. 7, the light-emitting structure 211 includes a plurality of screen dot regions, each screen dot region is formed by a plurality of screen dots 2111, and the light-emitting effect of the fan lamp 100 is realized by using the characteristics of the screen dots 2111. It can be known that the screen dots 2111 may destroy the total reflection condition inside the blade 2, so that light is emitted from the inside of the blade 2, that is, light is emitted from the lower surface of the blade body 21, thereby implementing the illumination function.

The preferred embodiment of this application has adopted the light-emitting mode of non-straight following formula, therefore, when the condition of the side of blade 2 is located to light source subassembly 3, when reducing the thickness of fan lamp 100, can introduce a problem, promptly, along with the increase of the length of blade 2, the light that reaches the blade 2 end can be weakened by a wide margin. To avoid this problem, in the present application, the area of the screen dot region and the distance from the screen dot region to the housing member 12 are designed to be positively correlated, or the density of the screen dots 2111 on the screen dot region and the distance from the screen dot region to the fan main body 1 are designed to be positively correlated. By the arrangement, the phenomenon that the light intensity of the original fan lamp 100 is different can be well solved, and the light uniformity of the fan lamp 100 is improved.

In a preferred embodiment, the area of the screen dot region, the density of the screen dots 2111 on the screen dot region, and the distance from the screen dot region to the receptacle 12 are all positively correlated. In other words, if the light intensity received by the screen dots 2111 close to the light source assembly 3 is strong, the area of the region is small, and the distribution of the screen dots is sparse. However, for the silkscreen dots 2111 far away from the light source assembly 3, the received light intensity is weak, the area of the region is larger, and the distribution of the silkscreen dots is dense, so that the light emitting effect of the whole light guide blade can be balanced, and the light emitting uniformity of the fan lamp 100 is greatly improved.

Preferably, the screen dot areas of the fan lamp 100 are divided into two rows and eight rows, and the areas of the screen dot areas in the same row and the densities of the screen dot 2111 thereon are the same. In other embodiments, the number of the screen dots 2111 may also be two rows and six rows, two rows and four rows, or one row and four rows, and the like, and may be set reasonably according to the actual size of the blade body 21, which is not further limited in this application.

In other embodiments, the area of the distribution of the screen printing dots 2111 and the distance from the screen printing dots 2111 to the receptacle 12 are designed to be positively correlated without setting the screen printing dots 2111 in a partition manner, or the density of the screen printing dots 2111 and the distance from the screen printing dots 2111 to the receptacle 12 are designed to be positively correlated, so that uniform light emission of the light guide blade can also be realized.

As shown in fig. 2-3, it can be seen that the light emitted from the light guide blade is more uniform due to the arrangement of the silk-screen dots 2111, so that the effect of uniform light emission of the fan lamp 100 is achieved, and the visual experience of the user is improved. The halftone dots 2111 may have any shape, such as circular or non-circular, etc.

In an embodiment, the blade body 21 is a planar structure, the thickness of the blade body 21 is in a uniform transition from thin to thick along the width direction of the blade body, the lower surface of the blade body 21 is horizontally arranged, that is, the blade body 21 is formed by inclining the upper surface of the blade body 21 relative to the lower surface thereof in a transition form from thin to thick, and the thinner end of the blade body 21 is located on the windward side. Therefore, the thickness of the blade body 21 changes gradually, so that the fan lamp 100 can drive more air around to flow in the rotating process, and generate larger air volume, thereby obtaining a good fan effect.

In the present embodiment, the number of the blades 2 is three, and the blades are arranged circumferentially at equal intervals on the circumferential portion of the rotor disk 11. Fewer blades 2 achieve a fanning, while also having less noise. In other embodiments, in order to improve the comfort of the air blowing, the light emitting area and the uniformity of the light emitting, the number of the blades 2 may also be increased by a proper amount, which is not further limited herein.

Referring to fig. 9-12, to further increase the wind power of the fan lamp 100, the blade body 21 may also adopt a curved surface structure, and the plane where the light emitting surface of the blade body 21 is located is crossed with the plane where the light incident surface 221 of the blade body 21 is located. Compared with the conventional flat blade, the blade 2 with the curved surface structure has a larger flow guide surface area. Therefore, when the fan lamp 100 is operated, the blade main body 21 arranged around the turntable 11 can effectively increase the flow rate of the air flow, thereby obtaining higher fan efficiency.

With continued reference to fig. 1 and 7, the receptacle 12 is provided with a first receiving cavity 121, and the blade root 22 is received in the first receiving cavity 121 and is fixedly connected to the receptacle 12. The blade root 22 is provided with a first mounting hole 222, the accommodating part 12 is correspondingly provided with a second mounting hole 122, one end of the chassis 111 close to the accommodating part is provided with a third mounting hole 1111, and a fastener such as a screw or a bolt is inserted into the third mounting hole 1111 after passing through the second mounting hole 122 and the first mounting hole 222, so that the fixed connection between the blade 2 and the accommodating part 12 is realized. In this embodiment, the third mounting hole 1111 is designed as a blind hole, and since the receiving member 12 is disposed close to the mounting wall with respect to the chassis 111, such parts as a fastening member are not in the visual field of the user, and thus the aesthetic appearance of the fan lamp 100 is improved. In other embodiments, the blade root 22 and the receptacle 12 may be fixedly connected by a snap connection or the like.

Further, the blade root 22 includes a yielding structure 223, the yielding structure 223 is formed by inward recess of the end of the blade root 22 close to the fan main body 1, the yielding structure 223 and the accommodating part 12 are enclosed to form a second accommodating cavity 224 (as shown in fig. 1), and the light source assembly 3 is arranged in the second accommodating cavity 224. The first accommodation chamber 121 communicates with the second accommodation chamber 224.

Referring to fig. 4 and 6, the light source assembly 3 can be fixed on the inner wall of the receptacle 12 by gluing or the like. Light source subassembly 3 includes base plate 31 and the lamp pearl 32 of setting on base plate 31, and lamp pearl 32 is close to into plain noodles 221 and sets up, and base plate 31 fixed connection is on the inner wall of holding piece 12, promptly, and light source subassembly 3 sets up the side direction at blade 2. Compare in traditional lamp pearl 32 and the upper and lower setting of light guide plate, the light source subassembly 3 setting of this application can reduce fan lamp 100's thickness well in the side direction of blade 2. Preferably, the substrate 31 is a printed circuit board (i.e., a PCB), and the lamp bead 32 is an LED lamp bead, which has the advantages of small volume, energy saving, environmental protection, long service life, high luminous efficiency, and the like, so that the fan lamp 100 can obtain a better light emitting effect. LED lamp pearl welding is on the PCB board, and evenly arranges on the PCB board. The specific quantity of LED lamp pearl can be set for according to actual demand, and this application does not do the restriction to this.

Preferably, the lamp beads 32 are symmetrically distributed on two sides of a vertical plane where the central axis of the light incident surface 221 is located, so as to further ensure the uniformity of the emitted light.

The fan lamp 100 further includes a control device (not shown) electrically connected to at least one of the light source assembly 3 and the turntable 11, so as to drive at least one of the blades 2 and the light source assembly 3 to meet different use requirements of users.
