Detailed Description

The present invention will be described in further detail with reference to the following drawings and examples.

Refer to fig. 2. The utility model provides a projection lamp, includes base 1, installs connecting piece 2 on base 1, installs 2 lamp shade 3 on the connecting piece and installs lamp plate 4 in lamp shade 3, is provided with LED light source 40 on lamp plate 4.

Refer to fig. 2 to 4. Base 1 is connected by two sections diameter different drum and is constituteed, including the great installation department of diameter 11 and the direct less first connecting cylinder 12, can place the drive power supply of LED light source in the 11 holes of installation department, first connecting cylinder 12 is used for being connected with connecting piece 2. The connecting piece 2 is formed by connecting a second connecting cylinder 22 and a third connecting cylinder 23 which have different diameters, and a limiting ring 21 is arranged on the outer side of the joint of the second connecting cylinder 22 and the third connecting cylinder 23. The second connecting cylinder 22 is inserted into the inner hole of the first connecting cylinder 12, and the two are fixed by screws or threads. The lamp shade 3 can be made by metal materials with good heat-conducting property such as aluminium, a section of thick bamboo, iron, the utility model discloses the preferred aluminum product die-casting that adopts forms. The lampshade 3 is overall spherical and comprises a round bottom ring 31 and a round top plate 32 which are arranged in parallel, and the bottom ring 31 and the top plate 32 are connected through a plurality of radiating fins 33 which surround the outsides of the bottom ring 31 and the top plate 32. The plurality of heat dissipation fins 33 have heat dissipation gaps 34 therebetween, and a projected pattern may be installed in the heat dissipation gaps 34 or the heat dissipation gaps 34 directly form the projected pattern. The lampshade 3 is fixedly connected to the external thread of the third connecting cylinder 23 through the internal thread of the inner hole of the bottom ring 31, and the limit ring 21 limits the screwing depth of the bottom ring 31. The lamp panel 4 can be installed in the inner hole of the bottom ring 31, and the light emitting direction of the lamp panel faces the top plate 32; or on the top plate 32 with its light exit direction towards the bottom ring 31. The utility model discloses the preferred installation more does benefit to the heat dissipation like this on roof 32, and lamp plate 4 is farther apart from base installation department 11, and the drive power supply in its heat is difficult for conducting to installation department 11, and drive power supply is more durable. The utility model discloses also can not set up connecting piece 2 the 12 outsides of first connecting cylinder set up the external screw thread, directly fix in the internal thread of 3 end rings 31 holes of first connecting cylinder 12 screw in lamp shade.

The utility model discloses a lamp shade is made to the good material of heat conduction, sets up the heat dissipation space on the lamp shade and constitutes the projection figure, and the lamp shade has the function of heat dissipation and projection figure concurrently, abandons traditional special radiator, has auxiliary component still less, and the structure is simpler, advantages such as product appearance design degree of freedom is bigger.

The above description of the specific embodiments is only the preferred embodiments of the present invention, and does not represent the limitation of the protection contents of the present invention, and any technical solutions that can be obtained by normal reasoning of the ordinary technicians in the spirit of the present invention are the protection scope of the present invention.
