The specific embodiment

Below with reference to accompanying drawing and combine embodiment to specify the utility model.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.

Shown in Fig. 1～4, according to the embodiment of the utility model, lighting comprises power module 10, first light fixture 20, radiating subassembly 30 and second light fixture 50.

Power module 10 is fixedly installed in the shell of water-tight, prevents that power module 10 is by airborne moisture attacks and can't operate as normal.

First light fixture 20 comprises base plate 21 and 12 led light sources 22.Base plate 21 is a cuboid, comprises two planes that are parallel to each other and are oppositely arranged, and one of them is positive, and another is the back side.12 led light sources 22 are installed on the front of base plate 21 jointly, are divided into two rows along the length direction of base plate 21,6 led light sources 22 that evenly are provided with at interval of every row.Parallel with one another between 12 led light sources 22, and through power module 10 power supplies.When one of them led light source 22 breaks down can't throw light on the time, only need this led light source 22 of dismounting to get final product.In order to play waterproof effect, 12 led light source 22 surface coverage layer of transparent watertight composition 23 is arranged, can prevent that under the prerequisite that does not influence illumination led light source 22 from damaging because of meeting water.In addition, the electric wire that connects between led light source 22 and the power module 10 is provided with first water joint, and this first water joint can protect the junction of electric wire and power module 10 not receive moisture attacks, prevents the generation of short circuit accident.

Be provided with through hole 24 at base plate 21 1 ends, the electric wire that connects led light source 22 passes from this through hole 24, is connected with power module 10 from the back side of first light fixture 20, can prevent that like this electric wire from influencing the normal illumination of lighting, also makes things convenient for the arrangement of taking in of electric wire.Four first light fixtures 20 are arranged along the direction perpendicular to base plate 21 length.First light fixture 20 plays main illuminating effect, and the led light source 22 of array can increase illumination intensity effectively.The light source here is not limited to led light source, also can select the light source of other kinds according to actual needs, throws light on like incandescent source.

Radiating subassembly 30 comprises substrate 31 and fin 32.Substrate 31 is a cuboid, comprises two planes that are parallel to each other and are oppositely arranged, and the plane of wherein closing on first light fixture 20 is for positive, is the back side away from the plane of first light fixture 20.Substrate 31 by thermal diffusivity preferably material process so that the heat that produces in first light fixture, 20 lighting process is is in time scattered and disappeared.Substrate 31 has 3 heat radiation through holes 33 along its length.Some fin 32 are arranged on the back side of substrate 31 along the length direction of substrate 31, and the distance between per two fin 32 is identical.

Each first light fixture, 20 back side disposes three radiating subassemblies 30, and the back side of the front of the substrate 31 of one of them radiating subassembly 30 and the base plate 21 of first light fixture 20 fits.All the other two radiating subassemblies 30 lay respectively at the both sides of this radiating subassembly 30, and are connected with this radiating subassembly 30 through bracing frame 40.Promptly three radiating subassemblies 30 are arranged on the back side of the base plate 21 of first light fixture 20, and set gradually along the width of first light fixture 20.Radiating subassembly 30 can produce the led light source 22 in first light fixture 20 effectively when working heat conducts and distributes, and led light source 22 can be damaged because of the gathering of heat.The arrangement mode of three radiating subassemblies 30 can make the led light source 22 in each first light fixture 20 under the situation that number increases, still can dispel the heat preferably, can not reduce radiating effect because of the increase of power.

Second light fixture 50 comprises housing 51 and LED lamp band 52.Housing 51 is looped around around four first light fixtures 20, is connected with power module 10.Be connected through bracing frame 40 between the base plate 21 of housing 51 and first light fixture 20.Housing 51 is provided with groove, is used to place LED lamp band 52.LED lamp band 52 comprises banded flexible PCB or banded printed circuit board, and is welded on the LED lamp pearl on flexible PCB or the printed circuit board.Flexible PCB or printed circuit board are connected with power module 10 through electric wire.In order to play waterproof effect, LED lamp band 52 is arranged in the water-tight layer of being processed by plastic tube 53, water-tight layer 53 is arranged in the groove of housing 51 again.The water-tight layer 53 here is not limited to plastic tube, can select other can play the water-tight layer 53 of waterproof effect according to actual needs.In addition, the electric wire that connects between LED lamp band 52 and the power module 10 is provided with second water joint, can protect the junction of electric wire and power module 10 can not damage because of the erosion of steam.Second light fixture 50 can play the effect of auxiliary first light fixture 20, increases brightness of illumination, simultaneously because housing 51 can be arranged to different shapes according to different needs, therefore can play the effect of decoration, and is both artistic and practical.In the present embodiment, the housing 51 away from second light fixture of an end of power module 10 is semicircle.

From above description, can find out that the utility model the above embodiments increase radiating subassembly through the back side at the LED lamp, very fast the conducting of a large amount of heats with the LED lamp produces when working can not influence normal lighting; Cancelled the lampshade of common covering whole LED lamp, reduced cost; Through water joint, water-tight layer and transparent watertight layer are set, under the prerequisite that does not influence the lighting function, improved the whole water resistance of lighting; Through increasing the floor light assembly of transformable shape, increased illuminating effect and also played decorative effect simultaneously.

More than be merely the preferred embodiment of the utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
