Summary of the invention
It is inhomogeneous to the present invention is directed to the light that LED lamp that above-mentioned prior art exists penetrates, the technical problem that range of exposures is little provides a kind of range of exposures wide, luminous evenly soft LED tower-shaped lamp, its luminous illumination effect that is similar to conventional incandescent can obtain good illumination and decoration effect.
Technical scheme of the present invention is achieved in that
A kind of LED tower-shaped lamp, comprise lamp holder, lamp socket and lampshade, in lamp socket, be provided with drive circuit board and coupled LED turriform illuminating module, described LED turriform illuminating module comprises base, on base, be provided with at least three LED light-emitting areas and in order to the support of fixed L ED light-emitting area, described LED light-emitting area surrounds a pyramid on support.
As preferably, described support comprises a support column, outwards be evenly distributed with a plurality of gripper shoes radially along the support column sidewall, zone between adjacent two gripper shoes is a LED light-emitting area fixed bit, be provided with a cover plate on the top of support column, extend side shield along the side of gripper shoe downwards by side edge thereof, the two ends, the left and right sides of side shield all exceed the tow sides of gripper shoe, and the two ends, the left and right sides of side shield all bend inwards and form in order to coat the bound edge at LED light-emitting area edge, and LED light-emitting area two ends are located in the slideway of bound edge and side shield formation.After the LED light-emitting area fixes, only expose light-emitting area, bound edge covers the edge of LED light-emitting area, make the LED light-emitting area can not break away from support, side shield props up the edge of LED light-emitting area, skew was become flexible about it can not taken place, thereby had not only improved mechanical strength, also made the fixing more solid and reliable of light-emitting area.
As preferably, be provided with screw in the bottom of support column, correspondence is provided with through hole in the base center, and a screw is screwed in the screw after passing through hole.Support links to each other by screw with base, and convenient disassembly is solid and reliable.
For better location, and prevent that support from rotating, as preferably, the bottom of side shield is provided with card base, the corresponding breach that is provided with ccontaining card base on the base periphery, and card base is plugged in the described breach.
As preferably, in same LED light-emitting area fixed bit, be connected with rib between the upper end of two bound edges, the upper end of last rib connects cover plate.Last rib covers the upper end of LED light-emitting area equally, not only stabilizes the upper end of LED light-emitting area, also makes integral body more attractive in appearance.
As preferably, on the lower surface of base, be provided with printed circuit board (PCB), the LED light-emitting area is provided with two electrode pins, and correspondence is provided with pin bores on base, and electrode pin welds together with printed circuit board (PCB) after passing pin bores.Printed circuit board (PCB) is arranged on the lower surface of base, and is more hidden, and integral body is more attractive in appearance.
Owing to be equipped with circuit on drive circuit board and the base, for preventing that it is short-circuited, as preferably, between drive circuit board and base, be provided with insulating trip, drive circuit board is provided with two electrode pins, correspondence is provided with pin holes on base, and electrode pins is plugged in the pin holes after passing insulating trip, and electrode pins and printed circuit board (PCB) welding.The setting of insulating trip makes compacter the contacting of drive circuit board and base, the space of having saved lamp socket.
As preferably, on each LED light-emitting area, be welded with a plurality of led chips.The power of led chip generally below 5W, so heat is easy to distribute, can not bring influence for illumination.
As preferably, on base, be provided with three LED light-emitting areas, described LED light-emitting area surrounds a triangular cone on support.The present invention is a triangular pyramid turriform illuminator, and its structural design is advantages of simple more.
Adopted the principle of the present invention and the beneficial effect of technique scheme to be:
The present invention is arranged on the LED light-emitting area on the side of pyramid, make its light that sends fully to arrive the upper area of lampshade, can also arrive the lower area of lampshade, so just having guaranteed does not have the brightness blind area in the outer 360 degree scopes of lampshade, and illumination is more even.
In addition, the present invention has also solved the fixation problem of LED light-emitting area, and the LED light-emitting area is arranged on the support, push away get final product on only needing to insert each LED light-emitting area in slideway, install very simply, and can not take place to be shifted and come off, after installing, again support is fixed on the base, very convenient.
The specific embodiment
The specific embodiment of the present invention is as follows:
Embodiment: a kind of LED tower-shaped lamp, as shown in Figure 1 and Figure 2, comprise lamp holder 1, lamp socket 2 and lampshade 3, in lamp socket 2, be provided with drive circuit board 4 and coupled LED turriform illuminating module 5, described LED turriform illuminating module comprises base 6, be provided with three LED light-emitting areas 7 and in order to the support 8 of fixed L ED light-emitting area 7, LED light-emitting area 7 is that class is triangular shaped on base 6, described LED light-emitting area 7 surrounds a triangular cone on support 8.
On each LED light-emitting area 7, be welded with a plurality of led chips 24.
Design main points of the present invention also are the structural design of support 8, before the present invention, once attempted on base, fixing earlier a pyramid, and then the LED light-emitting area that is adhesively fixed on the side of pyramid, but find in using that the LED light-emitting area comes off easily, and inconvenience is installed, causes displacement easily, influence aesthetic measure.So designed support of the present invention through repeatedly improving.
As Fig. 3, shown in Figure 4, described support 8 comprises a support column 9, support column 9 is a cylindrical shape, outwards be evenly distributed with 3 gripper shoes 10 radially along support column 9 sidewalls, zone between adjacent two gripper shoes 10 is a LED light-emitting area fixed bit, be provided with a cover plate 11 on the top of support column 9, extend side shield 12 along the side of gripper shoe 10 downwards by cover plate 11 edges, the two ends, the left and right sides of side shield 12 all exceed the tow sides of gripper shoe 10, the shape of side shield 12 is identical with the shape of LED light-emitting area side, and the two ends, the left and right sides of side shield 12 all bend inwards and form in order to coat the bound edge 13 at LED light-emitting area edge, LED light-emitting area 7 two ends are located in the slideway 25 of bound edge 13 and side shield 12 formation, and the led chip on the LED light-emitting area 7 all exposes outside.The bottom of side shield 12 is provided with card base 16, the corresponding breach 17 that is provided with ccontaining card base 16 on base 6 peripheries, and card base 16 is plugged in the described breach 17.In same LED light-emitting area fixed bit, be connected with rib 23 between the upper end of two bound edges 13, the upper end of last rib 23 connects cover plate 11.
