Detailed Description

Fig. 1 is a schematic top view illustrating a light-emitting fan assembly according to an embodiment of the invention. FIG. 2 is a side view schematic diagram of the light emitting fan assembly of FIG. 1. Fig. 3 is a partial perspective view illustrating the fan of the light-emitting fan assembly of fig. 1 being lifted. Fig. 4 is a partial perspective view of the light-emitting fan assembly of fig. 1. It should be noted that fig. 3 and 4 hide the base, the fan frame and the light effect element, and the fan of fig. 4 is indicated by a dotted line to clearly show the light emitting unit located inside.

Referring to fig. 1 to 4, in the present embodiment, the fan assembly 100 is disposed on a display card (not shown), for example, but the heat source applied by the fan assembly 100 is not limited thereto. The light-emitting fan assembly 100 of the present embodiment includes a base 110, a fan 120, at least one light-emitting unit 130, and a light-emitting element 140.

As shown in fig. 2, the fan 120 is rotatably disposed above the base 110. The fan 120 includes a central housing 121 and a plurality of blades 125 extending from the central housing 121. In the present embodiment, the central housing seat 121 of the fan 120 is non-light-transmissive, such as black, but the color of the central housing seat 121 is not limited thereto.

The light emitting unit 130 is disposed between the base 110 and the central housing 121 of the fan 120, and the central housing 121 covers the light emitting unit 130. The central housing 121 has a gap 122 near the base 110, and the gap 122 is located at one side of the light emitting unit 130.

In the present embodiment, the light emitting unit 130 is a side-emitting light emitting unit, and emits light in a side direction. Part of the light emitted by the light emitting unit 130 is shielded by the non-transparent central housing 121, and part of the light can pass through the gap 122.

As shown in fig. 1, in the present embodiment, the number of the light emitting units 130 is, for example, three, but the number of the light emitting units 130 is not limited thereto. In some embodiments, the number of the light emitting units 130 may also be one, two, or more than three. In addition, each light emitting unit 130 may include a red led 132, a green led 134, and a blue led 136. Of course, in other embodiments, the light emitting unit 130 may only have a single color led, and the kind of the light emitting unit 130 is not limited thereto.

When the fan 120 rotates, the notch 122 of the central housing 121 rotates, and when the notch 122 rotates to different angles, the different light emitting units 130 are corresponding to the notch 122, so that the light streams emitted by the light emitting units 130 are emitted from the notch 122.

In the present embodiment, the light emitting unit 130 can be controlled by a controller (not shown) to generate different light emitting effects. Specifically, the manufacturer may measure the waveform of the rotation speed of the fan 120 by using TACHO Pin (not shown) of the fan 120 according to the desired lighting effect, and write the related information into the controller, and the controller may control the switches of the red, green and

blue leds

132, 134, 136 in the light emitting unit 130 according to the rotation speed to obtain different lighting effects.

As shown in fig. 3, in the present embodiment, the central housing seat 121 is cylindrical, the notch 122 is recessed in the lower edge of the central housing seat 121, and the notch 122 occupies 5% to 20% of the lower edge of the central housing seat 121 (for example, occupies 18 degrees to 72 degrees of the circumferential angle). In a preferred embodiment, the gap 122 is between 10% and 15% of the lower edge of the central housing seat 121 (e.g., between 36 and 48 degrees of circumferential angle).

The gap 122 occupies the lower edge of the central housing 121 within the above range, so that the light is more concentrated and the chroma is more saturated. If the number of the light emitting units 130 is larger, the size ratio of the gap 122 to the lower edge of the central housing seat 121 may be smaller.

It should be noted that in other embodiments, the number of the gaps 122 is not limited to one, and the number of the gaps 122 may also be multiple. If the light emitting unit 130 emits light with different colors according to different time sequences, the more the number of the notches 122 is, the easier the light mixing is, and the easier the light effect with lower chroma after light mixing is generated. Of course, if the light emitting unit 130 emits only monochromatic light, the more the notches 122 are, the more the brightness is improved.

Referring back to fig. 1 and fig. 2, in the present embodiment, the light effect element 140 is disposed on the base 110 and surrounds the light emitting unit 130, and a projection of the light effect element 140 to the base 110 is larger than a projection of the fan 120 to the base 110. Therefore, the light effect element 140 is not shielded by the fan 120, and the user can see the light effect element 140 at the front side of the fan 120 (for example, looking from the top to the bottom in fig. 1).

In the embodiment, the lamp effect element 140 has a closed ring shape, but in other embodiments, the lamp effect element 140 may have a non-closed ring shape or other shapes (e.g., polygonal shape, irregular shape, etc.).

In the present embodiment, the light effect element 140 is, for example, a white reflector, but the color and type of the light effect element 140 are not limited thereto. The light-emitting unit 130 emits light suitable for passing through the notch 122 of the central housing 121, and then irradiates the inclined inner surface 142 of the light-emitting unit 140, and is reflected by the inclined inner surface 142 of the light-emitting unit 140 to emit the light in a direction away from the base 110.

In the present embodiment, the sloped inner surface 142 is a smooth surface, as shown in fig. 2. The inclination angle θ of the inclined inner surface 142 is between 30 degrees and 60 degrees, for example, 45 degrees, but the inclination angle θ of the inclined inner surface 142 is not limited thereto. In other embodiments, the inclined inner surface 142 may be a rough surface or a surface with a special shape to provide different optical effects.

In the present embodiment, the three light emitting units 130 may emit light of the same color or different colors. Since the light emitted from the light emitting unit 130 illuminates the light effect element 140, the user can see the same or different color light effects, or see the effects of a horse race light, a gradual layer color, a breathing light effect, a flashing light effect, etc. on the light effect element 140. In addition, due to the principle of persistence of vision, these light effects can appear in human eyes simultaneously or sequentially, and the whole circle of light effect elements 140 can be seen to emit light simultaneously or alternately.

In addition, as shown in fig. 2, in the present embodiment, the height of the light effect element 140 protruding from the base 110 is less than or equal to the distance between the fan blade 125 and the base 110. The low-height lamp effect element 140 is designed to be less likely to damage the wind flow of the fan 120, so that the fan 120 assembly can maintain a good heat dissipation effect.

It should be noted that, as shown in fig. 4, the light-emitting fan assembly 100 further includes a fan circuit board 150 disposed between the base 110 (fig. 2) and the central housing seat 121 of the fan 120 and electrically connected to the fan 120. The light emitting unit 130 is disposed on the fan circuit board 150.

Specifically, the fan circuit board 150 includes a first surface 152 (e.g., an upper surface away from the base 110) and a second surface 154 (e.g., a lower surface facing the base 110) opposite to each other. In this embodiment, the light emitting unit 130 may be disposed on the second surface 154 of the fan circuit board 150, and the first surface 152 of the fan circuit board 150 may be configured with a circuit (not shown) of the fan 120.

In the present embodiment, the design that the circuits of the light emitting unit 130 and the fan 120 share the same fan circuit board 150 can effectively save the number of circuit boards, and thus can save cost and space. In addition, in other embodiments, the light emitting unit 130 may not be disposed on the fan circuit board 150, for example, a wire is disposed on the base. Alternatively, the circuits of the light emitting unit 130 and the fan 120 may be disposed on the same surface of the fan circuit board 150, such as both on the first surface 152 or both on the second surface 154, which is not limited to the above.

Referring back to fig. 1 and fig. 2, the light-emitting fan assembly 100 further includes a fan frame 160 disposed on the base 110 and surrounding the fan 120 and the light-effect element 140. The height of the fan frame 160 protruding from the base 110 is greater than the height of the lamp effect element 140 protruding from the base 110 and the height of the fan 120 protruding from the base 110, so as to protect the fan 120 and reduce the probability of foreign objects directly contacting the fan 120. In addition, the fan frame 160 can be used to prevent the user's hand from directly contacting the rotating fan blades 125.

Fig. 5 is a schematic view of a fan of a light-emitting fan assembly according to another embodiment of the invention. Referring to fig. 5, a main difference between the fan 120a of fig. 5 and the fan 120 of fig. 3 is that, in the present embodiment, a light-transmitting member 123 is disposed in the gap 122 of the central housing seat 121. The light emitted from the light emitting unit 130 is suitable for passing through the light-transmitting member 123 located in the gap 122 of the central housing 121 and irradiating on the lamp effect element 140.

In the present embodiment, the light-transmitting member 123 is, for example, a convex lens or any element capable of converging light, and can be used to enhance the light brightness. Of course, in one embodiment, the light-transmitting member 123 may be a concave lens or other optical element to provide a special optical effect.

In addition, in the present embodiment, the light-transmitting member 123 and the central housing seat 121 are integrated, and can be manufactured by two-material injection, for example. Of course, in other embodiments, the light-transmitting member 123 and the central housing seat 121 may be separately manufactured and assembled together.

In this embodiment, the light-transmitting member 123 can provide special optical effects (e.g., more concentrated light and higher brightness), and can also achieve the effect of contributing to the uniformity of the weight. In addition, the light-transmitting member 123 can prevent dust and prevent foreign matters from entering the central housing seat 121.

In summary, the central housing of the fan of the light-emitting fan assembly of the present invention has a notch close to the base. The central shell seat covers the light-emitting unit, and the notch is positioned at one side of the light-emitting unit. The lamp effect element is arranged on the base and surrounds the light-emitting unit. The light emitted by the light-emitting unit is suitable for being irradiated on the lamp effect element after penetrating out of the notch of the central shell seat. Through the design, a user can see the visual effect generated by the light rays irradiating the lamp effect element.
