Description

The structural improvement of light fixture

Technical field

The utility model relates to a kind of light fixture, especially, relates to a kind of structural improvement that is arranged at the light fixture in the water.

Background technology

The open air is because of gardening or make the needed lighting decoration lamp of scape source, in order to be embedded on the ground or to be installed in the water, generally all can adopt the light fixture with water-proof function.Known light fixture 1 sees also shown in Figure 1ly, mainly is made of a body 11, loam cake 12, light-transmitting component 13, lamp source 14, waterproof washer 15.

Body 11 is a cylindrical shell, is provided with a ring seat 111 above body 11, and the surface of this ring seat 111 is provided with several screws 112, then is provided with one in the inboard of ring seat 111 and sets portion 113.

Loam cake 12, it is the annular cover of a hollow, this loam cake 12 can be covered on the ring seat of body 11, this loam cake 12 is provided with a loophole 121, the inboard of this loophole 121 is provided with a scrobicular ring 1211, the annular surface of loam cake 12 then is provided with the screw 112 corresponding through holes 122 with body 11 ring seats 111, and this loam cake 12 can combine with body 11 by the solid assembly S of spiral shell.

Light-transmitting component 13, normally make with light-transmitting materials such as glass, acryl, the upper end of this light-transmitting component 13 is a fitting portion 131, this fitting portion 131 can be embedded in the loophole 121 of loam cake 12, the lower end of light-transmitting component 13 then is a base 132, this base 132 can be embedded in the scrobicular ring 1211 of loam cake 12, and this base 132 has a waterproof washer 15, and this waterproof washer 15 can place in the portion that sets 113 of body 11 just.

Lamp source 14 provides this water proof lamp 1 required illumination to originate, and can be bulb or LED bulb usually.

Known light fixture 1 is when assembling, at first, be power line L to be passed to do with lamp source 14 by the bottom of body 11 connect, when lamp source 14 with power line L connect finish after, again lamp source 14 is fixedly arranged in the body 11, afterwards waterproof washer 15 is placed in the portion that sets 113 of body 11, again light-transmitting component 13 is placed on the waterproof washer 15, then loam cake 12 is covered on the ring seat 111 of body 11, with the solid assembly S of spiral shell loam cake 12 is locked in the ring seat 111 of body 11 at last, light fixture 1 after the assembling, as shown in Figure 2.

Above-mentioned known light fixture 1 is when using, it can be installed in the water or as the Recessed light on floor, yet via long use, waterproof washer 15 in the light fixture 1 is aging easily, sclerosis, cause the waterproof effect of sealing not good, therefore the waterproof washer 15 of light fixture 1 of getting off for a long time hardens because of plastics rotten, causes body 11 to be subjected to the capillarity of water or negative pressure easily and seeps water, and the moisture content that infilter in the body 11 then can cause the damage in lamp source 14.

Summary of the invention

Main purpose of the present utility model, be to provide a kind of structural improvement of light fixture, this light fixture has a body, a loam cake, a lamp source and a packing ring at least, this body has the portion of setting, and this lamp source is covered with a diffuser, and this diffuser has a flange, be arranged with packing ring on this flange, and place the setting in the portion of body, and and the bottom of diffuser has an opening, this opening is to insert for the lamp source to insert in the body after with glue the bottom being sealed again; This loam cake is the annular cover of a hollow, and this loam cake is to screw togather by solid assembly of spiral shell and body locking, and the opening with diffuser gives involution with glue in addition, when avoiding light fixture to insert in the water, in water infiltration body, causes the damage in lamp source.
