The luminous main body of described LED can be made up of two LED lamp pack modules, and wherein the male of a LED lamp pack module interconnects by the female of inserting the 2nd LED lamp pack module.Also can be made up of three LED lamp pack modules, wherein the male of a LED lamp pack module interconnects by the female of inserting the 2nd LED lamp pack module, and the male of the 2nd LED lamp pack module interconnects by the female of inserting the 3rd LED lamp pack module.

More specifically, an end of described lamp socket is provided with the male of projection, and it inserts in the female of a described LED lamp pack module.

Described LED lamp pack module comprises led array, the metallic core printed circuit board (PCB) that is arranged on described fin below that is installed in the fin top, the lens that are arranged on metallic core printed circuit board (PCB) below.

Combined LED lamp of the present utility model can also comprise bulb socket, and the female that an end of this bulb socket is provided with indent is connected with the male of described the 2nd LED lamp pack module or the 3rd LED lamp pack module.

More preferably, the radiating fin on the described fin is the column fin.The better effects if that so just makes heat radiation.

The utility model can carry out independent assortment by the LED lamp pack module that carries male and female, can assemble flexibly according to different requirements of customers like this, thereby satisfy different LED lighting power demands, and cost has also obtained reduction.

For making the utility model easier to understand, further set forth the utility model below in conjunction with accompanying drawing.

The specific embodiment

Description is described embodiment.

With reference to figure 1, Fig. 1 is a kind of combined LED lamp of the utility model structural representation in one embodiment; A kind of combined LED lamp of the present utility model can be divided into three major parts: be used to provide the lamp socket 2 of power supply, the luminous main body 1 of LED, the bulb socket 3 that is connected with this lamp socket.

The luminous main body 1 of above-mentioned LED is combined by two LED lamp pack modules 11.

With reference to figure 2, Fig. 2 is the explosive view after the combined LED lamp partition among Fig. 1, and wherein LED lamp pack module 11 comprises the led array 111 that is installed in fin 112 tops, the metallic core printed circuit board (PCB) (MCPCB) 113 that is arranged on fin 112 belows, the lens 114 that are arranged on metallic core printed circuit board (PCB) 113 belows.The effect of metallic core printed circuit board (PCB) (MCPCB) 113 wherein is in order to improve the heat radiation of circuit board aspect, be that original printed circuit board (PCB) is affixed on (as: aluminium, copper) on the better metal of another thermal conduction effect, come the enhance heat effect with this, and this sheet metal position is in printed circuit board (PCB).Being provided with a power storehouse 21 in lamp socket 2 inside in addition is used to provide LED luminous working power.

With reference to figure 3 and Fig. 4, an end of LED lamp pack module 11 is provided with the male 115 of projection, and the other end is provided with the female 116 of indent.Each LED lamp pack module each other by male and female to fetching the combination that realizes the luminous main body of LED lamp; Fig. 4 is the combination schematic diagram after two LED lamp pack modules connect among Fig. 3; In addition, also be provided with a male of protruding at an end of lamp socket 2 and connect, be communicated with power supply thereby the luminous main body of LED lamp is installed on the lamp socket in order to female with a LED lamp pack module; The female that one end of bulb socket 3 also is provided with an indent connects in order to the male with another LED lamp pack module, and the male of all parts all can be reached zero-clearance with female and cooperate butt joint.By sequential combination lamp socket 2, LED lamp pack module 11, bulb socket 3, by screw rod and nut above assembly is locked again, just can form a complete led street lamp module.

In order to adapt to different occasions or different clients' demand, the power that the LED illumination needs is different, in order to guarantee the service life of LED, along with the increase of lighting power, the area of fin also will increase accordingly, and the utility model is in order to design flexibly, can carry out independent assortment by the LED lamp pack module that carries male and female, can assemble flexibly according to different requirements of customers like this, and because of LED lamp pack module is shared, thereby cost is lower.
