The present invention relates to a fan technique and, in particular, to a uniformly luminous fan shield structure and a fan having the same.
In engines, central processing units (CPUs), hard disk drives (HDDs), power supplies, computer housings, or other products, usually a heat dissipation fan is utilized for cooling so as to prevent damage caused by overheating. In order to increase a value of the heat dissipation fan, a light source is installed in the heat dissipation fan for decoration and fun.
However, in practice, the luminous heat dissipation fan has the following disadvantages. Due to the structure design, configuration and a light emitting direction of the light source is limited, so only a small area or a single dot in the fan can emit light.
Accordingly, the target of the present invention is to solve the above-mentioned problems, on the basis of which the present invention is accomplished.
It is an object of the present invention to provide a uniformly luminous fan shield structure and a fan having the same. The light-transparent cover collaborates with the light emitting diode (LED) module to achieve uniform luminosity of the light-transparent cover.
Accordingly, the present invention provides a uniformly luminous fan shield structure which comprises a light-transparent cover and a light emitting diode module. The light-transparent cover includes a central area and a ring around the central area. The ring includes a groove. A side surface of the groove includes a plurality of light guide structures. The light emitting diode module is accommodated in the groove. The light emitting diode module includes a plurality of light emitting diodes. Each light emitting diode illuminates toward each light guide structure and the central area.
Accordingly, the present invention provides a fan having a fan shield structure. The fan has a uniformly luminous fan shield structure and a fan member. The fan shield structure includes a light-transparent cover and a light emitting diode module. The light-transparent cover includes a central area and a ring around the central area, the ring includes a groove, and a side surface of the groove includes a plurality of light guide structures. The light emitting diode module is accommodated in the groove, the light emitting diode module includes a plurality of light emitting diodes, each light emitting diode illuminates toward each light guide structure and the central area. On the fan member, the fan shield structure is disposed, and the fan member is arranged at one side of the fan shield structure.
The present invention further has the following functions. By using the light guide structure and light guide notches, the light emitted by each light emitting diode is uniformly distributed to most area of the light-transparent cover. The hexagonal substrate and the Y-shaped light guide supporter cover an overall circular surface, so that uniform luminosity is achieved.
The disclosure will become more fully understood from the detailed description and the drawings given herein below for illustration only, and thus does not limit the disclosure, wherein:
Detailed descriptions and technical contents of the present invention are illustrated below in conjunction with the accompany drawings. However, it is to be understood that the descriptions and the accompany drawings disclosed herein are merely illustrative and exemplary and not intended to limit the scope of the present invention.
Referring to
The light-transparent cover 10 can consist of polymethyl methacrylate (PMMA) resin. The light-transparent cover 10 has a central area 11 and a ring 12. The central area 11 includes a hexagonal substrate 111 and a plurality of standing plates 112 extending upwards from a periphery of the hexagonal substrate 111. A plurality of light guide notches 113 is disposed on an inner surface of each standing plate 112.
The ring 12 is a circle around the central area 11. A groove 121 is disposed inside the ring 12, and the groove 121 has a shape matching with a shape of the ring 12. The groove 121 is formed by a bottom plate 122 and by an inner side wall 123 and an outer side wall 124 connected to the bottom plate 122. The bottom plate 122, the inner side wall 123 and the outer side wall 124 are of round annular shape. A plurality of light guide structures 125 are formed on a surface of the inner side wall 123, and the light guide structure 125 is a longitudinal notch. The ring 12 includes a wire outlet opening 126 at one side of the outer side wall 124.
Furthermore, the central area 11 and the ring 12 are connected by means of a plurality of Y-shaped light guide supporters 13, a bottom end of each of the Y-shaped light guide supporters 13 is connected to a corresponding corner of the hexagonal substrate 111, a top end of each of the Y-shaped light guide supporters 13 is connected to an inner surface of the ring 12, and a Y-shaped channel 131 is disposed inside each of the Y-shaped light guide supporters 13. A plurality of connection elements 14, spaced apart at equal intervals, extend from an outer circumferential surface of the ring 12, and a top end of each of the connection elements 14 includes a hollow cylindrical pillar 141.
In the present embodiment, the light emitting diode module 30 is of round annular shape. The light emitting diode module 30 includes an annular circuit 31 and a plurality of light emitting diodes 32 disposed on an inner surface of the annular circuit 31. Each light emitting diode 32 is a red-green-blue (RGB) light emitting diode (LED). The annular circuit 31 is accommodated in the groove 121 of the ring 12. Each light emitting diode 32 illuminates toward each light guide structure 125 and the central area 11. By utilizing a controller (not illustrated), each light emitting diode 32 can emit light which may be continuous, intermittent, blinking, or in other forms. A wire 33 is electrically connected to one side of the annular circuit 31, and the wire 33 protrudes out of the ring 12 from the wire outlet opening 126.
Moreover, the uniformly luminous fan shield structure 1 further includes a press plate 50, and the press plate 50 is of round annular shape. The press plate 50 is disposed corresponding to the groove 121 and is connected to the ring 12 to thereby enclose the light emitting diode module 30 between the ring 12 and the press plate 50. An engagement block 51 extends from one side of the press plate 50, and the engagement block 51 is engaged with the wire outlet opening 126.
Referring to
In summary, the uniformly luminous fan shield structure and the fan having the same certainly can achieve anticipated objectives and solve the conventional defects. The present invention also has novelty and non-obviousness, so the present invention completely complies with the requirements of patentability. Therefore, a request to patent the present invention is filed pursuant to patent law. Examination is kindly requested, and allowance of the present application is solicited to protect the rights of the inventor.
