When using above-mentioned leading 700, when opening tap 700, water sequentially passes through Down lamp body interior and tap 700, and flows out.Flow through Down lamp body flowing water to cool LED down 60.
Above-mentioned LED down 60 can not only be thrown light on when washing one's hands, and radiating effect is better, long service life.And quantity and the position of LED luminescence unit 200 can being regulated as required, meet the different user demands of people, strengthening the brightness of LED down 60 by increasing LED luminescence unit 200, and then increase its modulability further, expand the scope of application.
According to actual conditions, Down lamp body has the first opening, and tap 700 has connector, and the first opening is connected with the connector of tap 700.In the present embodiment, the connector bolt of the first opening and tap 700.In other embodiments, the first opening also can with leading 700 clampings etc.
In order to increase the sealing of the first opening and connector, such as, LED down 60 also comprises sealed tube, the sheathed connector of sealed tube and the first opening, and hides the join domain of connector and the first opening.For another example, the free end of the first opening and the free end of connector all offer standing groove, and sealed tube is placed in standing groove.Wherein, free end refers to also can be understood as the end that the first opening is connected with connector, and the first opening and connector are step structure.
Sealed tube enhances the sealing of LED down 60, make its stability and security better.
It is pointed out that the water resistance in order to increase LED down 60, such as, LED down 60 also comprises bucker, and bucker and Down lamp body surround host cavity, and mount pad 110 and LED luminescence unit 200 are all positioned at host cavity.Such as, Down lamp body offers chute, bucker part is placed in chute, and slip is arranged on Down lamp body.For another example, the Down lamp inner body wall of hollow is coated with water-repellent paint.Which increase the water proofing property of LED down 60, increase safety in utilization, and the service life of LED down 60.
In addition, in order to increase the versatility of LED down 60, such as, Down lamp body is also provided with rack.Rack is multiple, and multiple rack both can be arranged in parallel, can distribute radially again.
Rack adds the versatility of LED down 60, makes it place the article such as towel, increases its scope of application further.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this description is recorded.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
