Description

A kind of annular is lamp under water

Technical field

The utility model belongs to underwater illuminating device, is specially a kind of lamp under water that is used for regional decorative lighting under water.

Background technology

At present, along with the raising of people's living standard, the construction in city also further improves; Many cities are decorative beautifying environment, enrich people's spare-time cultural life, often are equipped with in places such as fountain, water scenery sculpture, waterfall and the swimming pool of park plaza, river courses with the pond to want the decoration light that cooperates.Existing underwater lamp is LED lamp, swimming pool lamp etc. under water again, mainly is the LED illuminating product that is used for water scenery zone decorative lighting, also can be used for illuminating fountain or shine tree, and it is used sizable flexibility equally.

Existing underwater lamp is installed in the side of fountain water pipe mostly; During use, because side lamp can not be beaten the water of bright fountain ejection fully, caused illumination and water spray not to reach perfect the cooperation, light is not concentrated, and utilization rate is low, and illuminating effect is bad.In addition, be installed in the inconvenience that the side not only can cause lamp to install and fix, and damaged artificially or steal easily.At present, also do not address this problem better technical scheme.

The utility model content

Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and the improvement of lamp under water of a kind of annular is provided, this under water lamp should have easy for installation firmly, the characteristics of good, the good illumination effect of theftproof performance.

The technical solution adopted in the utility model is:

A kind of annular is lamp under water, comprise lamp housing and loam cake, it is characterized in that: described lamp housing is connected the back and forms sealed cavity with loam cake, in cavity, be provided with one group of LED lamp, be provided with the through hole that runs through both in the center of described lamp housing and loam cake, above-mentioned LED lamp is evenly distributed on the periphery of through hole, is provided with the screw thread that is spirally connected with the cabling water pipe on the through hole at lamp housing place.Be provided with the screw thread that is connected with the cabling water pipe thread by middle part, during installation, water pipe can be passed in the middle of lamp body, thereby reach characteristics easy for installation, close and firm at lamp body.Simultaneously, because water pipe is fixed on the middle part of lamp body, the light that lamp body is sent is concentrated evenly, and in the parallel coincidence of water spray, good illumination effect, utilization rate height.

As preferably, the inside of described lamp housing is provided with aluminium base, and described one group of LED lamp is evenly distributed on the aluminium base.

As preferably, described aluminium base is provided with several and is distributed in constant-current driven chip between the LED lamp; By constant-current driven chip evenly is set on aluminium base, the current constant of the feasible LED lamp of flowing through is constant, has not only increased the stability of LED lamp, but also has improved the service life of LED lamp.

As preferably, the upper surface of described aluminium base evenly is coated with one deck water-proof silica-gel.Described water-proof silica-gel is coated on the upper surface of constant-current driven chip and LED lamp socket, has increased light fixture ground water resistance, has avoided causing short circuit, burning LED lamp and interlock circuit thereof because of the light fixture infiltration.

As preferably, evenly be shaped on one group of concave shaped heat radiation ring recess that is parallel to each other on the outer wall of described lamp housing; Concave shaped heat radiation ring recess can increase area of dissipation, improves the thermal diffusivity of light fixture integral body, thereby prolongs the service life of light fixture.

As preferably, described loam cake by the annular upper end lid that is threaded in the lamp housing top outer edge, be connected to the ring cowling of lamp housing middle part inner recess and the safety glass that is arranged between annular upper end lid, the ring cowling constitutes, all link to each other between described annular upper end lid, safety glass and the ring cowling by the water proof rubber circle.Be connected with the tight of lamp housing for increasing loam cake, on described ring cowling, also itself and lamp housing fixed by screw.

As preferably, be provided with the water proof rubber circle between described annular upper end lid and the lamp housing top outer edge.The purpose that the water proof rubber circle is set is that further anti-sealing infiltrates in the lamp body, influences the service life of light fixture.

The beneficial effects of the utility model are:

1, easy for installation, good anti-theft effect, because this annular lamp under water is that the cabling water pipe is passed at the lamp body middle part when mounted, owing in lamp body, be provided with shaft-like screw thread on the ring outer wall, making lamp body can rotate socket is fixed on the water pipe, easy for installation, and do not need to use other connector, reduced installation cost; Because this lamp body passes water pipe and is fixed on the water pipe, the constant intensity height artificially damages and removes difficulty, has reduced unnecessary expenses in addition.

2, the lamp socket under water of this annular is fixed on the water pipe, makes lighting concentrate evenly, and the water of shower nozzle ejection is beaten fully bright, and good illumination effect, utilization rate height make illumination and water spray reach perfect and cooperate.

The specific embodiment

Below by specific embodiment the technical solution of the utility model is done and to be described further.

Shown in Fig. 1-5, present embodiment comprises lamp body 1, and lamp body is made of lamp housing 4 with cable turnover linear sealing

mouth

2,3 and the loam cake 12 that is threaded in the lamp housing top outer edge.The inside of lamp housing is provided with aluminium base 5, and the aluminium base upper surface is 12 LED lamps of distribution (the LED lamp constitutes by being arranged on the LED particle 19 in the lamp socket and the outer peripheral lens 18 of lamp socket being set) evenly.Lamp body is a loop configuration, and the center of lamp housing and loam cake is provided with the through hole 7 that runs through both, and the LED lamp is evenly distributed on the periphery of through hole, is provided with the screw thread 8 that is spirally connected with the cabling water pipe on the through hole at lamp housing place.Be provided with the screw thread that is connected with the cabling water pipe thread by middle part, during installation, water pipe can be passed in the middle of lamp body, thereby reach characteristics easy for installation, close and firm at lamp body.Simultaneously, because water pipe is fixed on the middle part of lamp body, the light that lamp body is sent is concentrated evenly, and in the parallel coincidence of water spray, good illumination effect, utilization rate height.

Described aluminium base is provided with 12 constant-current driven chips 9 between the distribution LED lamp, by constant-current driven chip evenly is set on aluminium base, the current constant of the feasible LED lamp of flowing through is constant, has not only increased the stability of LED lamp, but also has improved the service life of LED lamp.
