1. Field of the Invention
The present invention relates to lighting fixture technology and more particularly, to a waterproof outdoor lighting fixture which uses a locating member to lock a waterproof gasket to a lamp holder, avoiding falling of the waterproof gasket during replacement of the lamp bulb.
2. Description of the Related Art
In consideration of numerous factors, such as creating a special atmosphere or for allowing more people to participate, banquet, toastmasters, night market trafficking and many other activities may be held at night. In a night garden, landscape place, or any place for night activities, lighting is quite important. When installing an outdoor lighting fixture, the waterproof measure must be taken into account to avoid an electrical leakage.
To seal the gap between the lamp bulb and lamp socket of an outdoor lighting fixture against water or moisture, a waterproof gasket is usually used. However, when replacing the lamp bulb of an outdoor lighting fixture, the waterproof gasket will be moved out of the lampshade, and the user may forget to put the waterproof gasket back into the inside of the lampshade, resulting in waterproof failure.
The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a waterproof outdoor lighting fixture which uses a locating member to lock a waterproof gasket to a lamp holder, avoiding falling of the waterproof gasket during replacement of the lamp bulb and effectively sealing the lamp holder against outside moisture.
To achieve this and other objects of the present invention, a waterproof outdoor lighting fixture comprises a lamp holder having a front lamp bulb socket for receiving a lamp bulb, an outer shell molded on the periphery of the lamp holder and having locating holes located on an inner wall of a lampshade portion thereof, a waterproof gasket tightly press-fitted into the lampshade portion of the outer shell, and an annular locating member fastened to the lampshade portion of the outer shell to lock the waterproof gasket.
Referring to
The lamp holder 1 comprises a front lamp bulb socket 11, and a plurality of electrode plates 12 backwardly extended from the rear side of the front lamp bulb socket 11 in a parallel manner.
The outer shell 2 molded on the periphery of the lamp holder 1, comprising a body portion 21 surrounding the lamp holder 1, a lampshade portion 22 forwardly extended from the front end of the body portion 21 and shaped like a horn, a plurality of locating holes 221 located on the inner wall of the lampshade portion 22, and a tubular rear guard portion 23 backwardly extended from the rear end of the body portion 21 and spaced around the electrode plates 12 of the lamp holder 1.
The waterproof gasket 3 has a center hole 31 cut through opposite front and back sides thereof at the center. Further, the periphery of the waterproof gasket 3 is tapered, fitting the inner wall of the lampshade portion 22. Further, the waterproof gasket 3 is made of an elastically deformable material, for example, rubber.
The locating member 4 comprises an annular base 41, a center opening 42 surrounded by the annular base 41, and a plurality of locating rods 43 transversely outwardly extended from the annular base 41 corresponding to the locating holes 221 of the outer shell 2. Each locating rod 43 has a beveled guide face 431.
During installation of the waterproof outdoor lighting fixture 10, insert the waterproof gasket 3 into the lampshade portion 22 of the outer shell 2, and then insert the locating plate 4 into the lampshade portion 22 of the outer shell 2 to stop the waterproof gasket 3 against the front end of the lamp holder 1 and to force the locating rods 43 of the locating plate 4 into the respective locating holes 221 of the outer shell 2. By means of the beveled guide faces 431 and elastically deformable material property of the locating plate 4, the locating rods 43 of the locating plate 4 can easily be forced into respective locating holes 221 of the outer shell 2. When assembled, the waterproof gasket 3 is tightly squeezed between the lamp holder 1 and the locating plate 4.

When using the waterproof outdoor lighting fixture 10, connect the electrical plug 61 of the power cable 6 to an electrical outlet or power supply device, and then fasten the pointed pin 652 of the anchor member 65 to the ground 7, and then open the hinged seal cap 63 from the electrical socket 62, and then insert the electrode plates 12 of the lamp holder 1 into the electrical socket 62 to force the tubular rear guard portion 23 onto the periphery of the electrical socket 62 tightly, prohibiting outside water or moisture from entering the inside of the waterproof outdoor lighting fixture 10.
In conclusion, the invention provides a waterproof outdoor lighting fixture 10, which uses the locating member 4 to lock the waterproof gasket 3 to the lamp holder 1, avoiding falling of the waterproof gasket 3 during replacement of the lamp bulb 5 and effectively sealing the front lamp bulb socket 11 of the lamp holder 1 against outside moisture.
Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
