Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1,2,3, 4, a kind of LED light module, comprises LED 2, six the first pcb board 1, second pcb boards 3 and connecting line (not indicating in figure); Described second pcb board 3 is arranged on the bottom of the first pcb board 1, and is welded to connect by connecting line and the first pcb board 1; It is characterized in that: described every two of six the first pcb boards 1 are welded together, and combination is in positive hexa-prism; Described second pcb board 3 is regular hexagon pcb board; Described first pcb board 1 and the second pcb board 3 are welded and fixed, and form pcb board integrative-structure; Described integrative-structure in tubular construction;
The whole pcb board of the utility model adopts stereoscopic arrangement, and namely six piece of first pcb board 1 is combined in positive hexa-prism by a part, forms a ventilation shaft; Second pcb board is arranged to regular hexagon shape by another part, and hexagonal length of side is less than the length of side of six prisms, is welded on the bottom of six prism pipelines by solid copper enamel-covered wire, the effect played conduction simultaneously and support;
Described first pcb board 1 is rectangle pcb board, six rectangle first pcb boards 1 are welded to connect between two, combine and form positive hexagon prism-shaped, and the PCB combining structure of this positive hexagon prism-shaped is Kong Zhu, form a ventilation shaft up and down, make PCB combining structure itself form a heat dissipation channel;
Described connecting line is solid copper enamel-covered wire, adopts solid copper enamel-covered wire the second pcb board to be welded on the bottom of six rear positive six prism pipelines of a PCB combination, so both plays and firmly connect and supporting role, play again the effect of conduction;
The centre position of described second pcb board 2 is provided with manhole 4, utilizes this through hole 4 to make whole light emitting module through, form a through heat dissipation channel, and the passage formed can realize convection current, substantially increases the radiating effect of light emitting module;
Described first pcb board 1 and the second pcb board 2 include copper clad plate and Copper Foil, and described Copper Foil is arranged on described copper clad plate; Adopt monoblock Copper Foil to be coated on copper clad plate, so just make whole PCB use Copper Foil to connect, realize outside good connection, also maximum area ground realizes heat radiation, makes pcb board itself have heat sinking function, further increases the radiating effect of total; Described copper clad plate is the double-deck copper clad plate of FR4, and thickness is 0.3mm; The thickness of described Copper Foil is 20Z;
The double-deck copper clad plate of FR4 of what the first pcb board 1, second pcb board 2 of the present utility model adopted is 0.3mm thickness, copper thickness 2OZ(70 μm); Simultaneously in order to make PCB increasing heat radiation area, in the design of pcb board, do not adopt line and curve connection, but adopt monoblock Copper Foil to connect, maximum magnitude utilize Copper Foil as fin;
First pcb board 1, second pcb board 2 of the present utility model also can directly adopt the aluminium base of tubular type macrostructure to form;
Described LED 2 is straight cutting F8 lamp pearl, and power is 0.5W; The nominal power of F8 light emitting diode is 0.5W, and rated current is 120MA, points out in the operation instruction that supplier provides, this LED is when without radiator, long operating current does not exceed 60 milliamperes, and during without radiator, LED can not work long hours in 120 milliamperes of situations;
