Therefore not having technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing this reality
With under novel the effect of can be generated and the purpose that can reach, should all still falling in the revealed technology contents institute of the utility model
In the range of capable of covering.Meanwhile it is cited such as "upper", "lower", "left", "right", " centre " and " one " in this specification
Term is merely convenient to being illustrated for narration, rather than to limit the enforceable range of the utility model, the change of relativeness
Or adjustment, in the case where changing technology contents without essence, when being also considered as the enforceable scope of the utility model.
Fig. 1-3 shows one embodiment of the utility model LED lamp.The LED lamp includes LED light source module 2, electricity
Source module 3 and radiator 1.
Radiator 1 includes heat sink 11, and power module 3 is mounted on 11 back side of heat sink, is located in 11 back side of heat sink
Between position, in specific installation process, mode shown in Fig. 1 may be used, power module 3 is mounted in power pack 31, then will
Power pack 31 is fixed on the back side of heat sink 11, and power supply sealing ring 32 can be arranged between power module 3 and heat sink 11.Heat sink
11 back sides may also include several cooling fins 12, to enhance heat dissipation effect.
LED light source module 2 includes multiple, is 6 in the present embodiment, and each LED light source module 2 includes substrate and is located at
Lamp bead on substrate.This 6 LED light source modules are mounted on the front of heat sink 11, such as are fixed by screw or heat conduction gluing
Patch, and positioned at the both sides of the position of installation power module 3.Several through-holes 13 are offered on heat sink 11, through-hole 13 opens up position
It sets between LED light source module 2 and between LED light source module 2 and power module 3, i.e., as shown in Figures 2 and 3, LED light source mould
Some mechanical connection is formed by heat sink 11 between group 2 and between LED light source module 2 and power module 3 in structure, not
Junction is through-hole.Each LED light source module 2 is connect with 3 circuit of power module respectively, such as each LED light source module 2 can divide
It is not connect with shared adapter plate for circuit 33, adapter plate for circuit 33 is connect with 3 circuit of power module.
Each LED light source module 2 may also include lampshade component 21, including cover on the lens or light-transmitting plate on substrate and lamp bead
And the appurtenances such as surface frame, protection network.The composition of above-mentioned lampshade component 21 and its existing LED light can be selected with assembly method
Existing design can be used in the structure of tool, the in other words combination of light source module group and lampshade component, and difference lies in by pacifying in existing design
One mounted in heat sink becomes mutually independent multiple.
As shown in Figure 1, LED lamp may also include holder 4, for lamps and lanterns in the installation using position, also by the holder 4
The irradiating angle of adjustable luminaire.
Above-described embodiment is the exemplary illustration to the utility model LED lamp, and plurality of feature can be by alternative
It realizes, such as：
The shape of through-hole can be various, be not limited to strip shown in figure；
Power module can be the standalone module recorded such as above-described embodiment, be fixed by power pack and heat sink, also may be used
By be it is existing in the form of, i.e., by power module be mounted on heat sink on power source cavity body in；Light source module group, radiator and heat sink
It is not limited to rectangular or rectangle, can be the other shapes such as circle；
Distribution of the light source module group on heat sink is not limited to form shown in Fig. 2, can also be for example, by using from all around
Around the form of power module, it is clear that the quantity of light source module group is also not necessarily limited to 6；
Cooling fin can be straight panel shape shown in Fig. 1 and 3, can also be the other shapes such as corrugated, can be such as Fig. 3 institutes
Show and is arranged in parallel within the cooling fin back side, it also can be for example, by using other forms such as annular spreads from inside to outside.
