with reference to fig1 , a lighting device with fluid wave projection according to the present invention comprises a lamp support 10 , a wave - generating apparatus 20 and a light source 30 . the wave - generating apparatus 20 is installed on top of the lamp support 10 , and the light source 30 is installed below the wave - generating apparatus 20 . the light emitted by the light source 30 travels through the wave - generating apparatus 20 to produce a wave - like projection at the other side of the wave - generating apparatus 20 . fig2 is an exploded schematic view of the preferred embodiment of the present invention . referring to fig1 and 2 , the structure of the lamp support 10 here serves only for illustrative purposes and is not limited thereto . the lamp support 10 includes a fixing member 11 for the installation of the light source 30 and a bearing member 12 for the installation of the wave - generating apparatus 20 . fig3 is a cross - sectional schematic view of a wave - generating apparatus in accordance with a preferred embodiment of the present invention . with reference to fig3 , the wave - generating apparatus 20 includes a tank body 21 , a fluid 22 and a pump 23 . the tank body 21 of the preferred embodiment is a cylinder , but its shape is not limited thereto . it may be a cuboid or any other shape depending on the shape of the bearing member 12 . the tank body 21 includes a cover 211 and a bottom plate 212 . the cover 211 seals the tank body after the tank body 21 is filled with the fluid 22 . the cover 211 and the bottom plate 212 are made of translucent material , such as glass , acrylic , or other similar materials , so that the light emitted by the light source 30 may pass through . the structures of the cover 211 and the bottom plate 212 may be any combination of a plane , a convex dome or a concave dome , but not limited thereto . the dome - like structure creates unique light concentration or dispersion , which variegates the projection effect . the fluid 22 is to be filled into the tank body 21 . the minimum amount thereof is one that allows the pump 23 to draw in and discharge water , and the maximum amount thereof is one that may fill the whole tank body 21 . the fluid 22 is translucent , and may be water or fluid of other density . it may be colorless or in any color . the preferred embodiment of the present invention utilizes the pump 23 as the wave - generating unit , but not limited thereto . the pump 23 is a conventional device commonly employed in water gardening . it includes a water outlet 231 and a water inlet 232 , and is powered with electricity by a first power supply cord 233 . often a sucker ( not shown in the drawing ) is disposed at the water inlet end thereof to fasten the pump 23 to the bottom plate 212 . in the present embodiment , a fastening board 214 protrudes upwardly from the bottom plate 212 to fix the pump 23 to one corner of the tank body 21 . besides , a groove ( not shown in the drawing ) may be formed protruding downwardly from the bottom plate 212 of the tank body 21 to fix the pump 23 in the groove . on the other hand , the first power supply cord 233 connected with the pump 23 may extend outwardly through a through hole 213 formed at the bottom plate 212 . the through hole 213 may be sealed with water - proof sealant to prevent the fluid 22 from leaking out and maintain the sealed state of the tank body 21 . there is no specific limitation to the type of light source 30 . it may be an incandescent light bulb , a fluorescent tube , a halogen lamp , or a light - emitting diode . the color of the light is not limited to white or yellow ; other colors may apply . the number of the light source 30 is not limited , either . it may be single or plural . please refer to fig2 again . when assembling the lighting device with fluid wave projection of the present invention , first , the first power supply cord 233 , which is connected to the pump 23 , is connected with the second power supply cord 31 , which is connected to the light source 30 . then the light source 30 and wave - generating apparatus 20 are installed in sequence to the fixing member 11 and the bearing member 12 , respectively . thus the assembly of the lighting device with fluid wave projection is rather simple . a lampshade 32 may be further installed around the light source 30 to enhance the aesthetics of the lighting device and soften the light emitted . the design of the lampshade 32 is not limited to the drawing . it may be varied to fit the lamp support 10 or to fulfill the lighting requirement . fig4 is a schematic view of the projection by the embodiment of the present invention . when the lighting device with fluid wave projection is assembled , the power supply may be switched on to turn the light source 30 on and actuate the pump 23 . in the present embodiment , the fluid 22 fills only part of the tank body . after drawn in , the fluid is discharged toward the cover 211 located at the top of the tank body 21 and forms unique wave marks at the cover 211 before it falls down , which results in the desired irregular variations of wave marks . the light emitted by the light source 30 passes through the irregular wave marks generated by the wave - generating apparatus 20 and forms projection of aforementioned wave marks at the other side . the installation position and discharge direction of the pump 23 is not limited and may be varied depending on the desired effect . the aforementioned wave mark projection may be cast on the wall or on the ceiling to variegate the lighting effect and enhance the uniqueness of the aesthetics . furthermore , the waves of the fluid 22 are generated in the sealed tank body 21 , which overcomes the disadvantage associated with conventional water lamp caused by the fluid circulation in an open environment . fig5 is a second embodiment of the present invention . referring to fig5 , the wave - generating unit is a vibrator 24 instead of the aforementioned pump 23 . the vibrator 24 may be installed at the center of the tank body 21 of the wave - generating apparatus 20 , but not limited thereto . the vibrator 24 is capable of generating a predetermined frequency . the vibration thereof enables the fluid 22 to produce concentric ripples with the vibrator 24 as the center . through the projection of the light source 30 , another unique lighting effect is achieved . although the present invention has been described with reference to the preferred embodiment thereof , it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims .
a lighting device capable of producing fluid wave projection is disclosed herein . the lighting device includes a lamp support having a bearing member , a wave - generating apparatus , and at least one light source . the wave - generating apparatus is installed on the bearing member and includes a translucent tank body within which a translucent fluid is contained as well as a wave - generating unit immersed in the fluid and installed in the tank body . the light sources are installed at one side of the wave - generating apparatus so that the light emitted therefrom travels through the wave - generating apparatus and produces wave projection .
