Abstract
The utility model discloses a novel LED street lamp radiating device with a membrane circuit. The novel LED street lamp radiating device comprises a shell, an LED bead, a membrane circuit board and an aluminum radiator. Lead pins on two sides of the LED bead are welded on the membrane circuit board, a protruding radiating point is arranged on the upper surface of the aluminum radiator, the membrane circuit board is pasted on a plane of the aluminum radiator which is fixedly mounted in the shell, and a layer of copper foil is coated on the upper surface of the radiating point of the aluminum radiator. The novel LED street lamp radiating device with the membrane circuit is simple in structure and low in cost, can omit heat conduction process for heat generated when the LED bead works, thus radiating effect is improved, and service life of the LED street lamp is prolonged.
Description
Technical field
The utility model relates to LED street lamp field, relates in particular to a kind of novel thin film circuit LED heat radiating device of road lamp.
Background technology
Present traditional LED road lamp cap radiating mode is that LED lamp pearl is coated conduction estersil and is welded on the aluminium base again, on aluminium base, coats conduction estersil then, is close to aluminium base to be fixed on the aluminium radiator, through shell heat-dissipating fin and cross-ventilation heat radiation again.Heat transfer needs four processes like this, the link of how conducting heat together, and heat conduction efficiency reduces once, adds that the thermal conductivity factor of conduction estersil is little, and heat-conducting effect obviously reduces, and causes LED lamp holder radiating effect low, and LED street lamp light decay is big, the life-span short.
Summary of the invention
For solving the problems of the technologies described above, the utility model technical scheme provides a kind of LED lamp pearl directly to be connected with aluminium radiator, reduces the LED heat radiating device of road lamp of heat transfer link, raising radiating effect.
In order to achieve the above object, the technical scheme of the utility model is: a kind of novel thin film circuit LED heat radiating device of road lamp comprises shell; LED lamp pearl, film circuit board, aluminium radiator; The pin of said LED lamp pearl both sides is welded on the described film circuit board; Said aluminium radiator upper surface is provided with the heat radiation point of protrusion, and described film circuit board sticks on the aluminium radiator plane, and aluminium radiator fixedly mounts in the enclosure.
The further improvement of the utility model is: described heat radiation point upper surface plating one deck Copper Foil; Heat radiation point and Copper Foil are inserted in that circular hole corresponding on the film circuit board is interior to become matched in clearance; The protrusion height of heat radiation point and Copper Foil and thin film circuit plate thickness coupling are so that film circuit board and aluminium radiator are fitted.
The beneficial effect of the utility model is: the heat that LED lamp pearl is produced passes to aluminium radiator through Copper Foil and heat radiation point; Again through shell and air exchange; Not only simple in structure, cost is low, and service life because of having reduced the heat transfer link, having improved radiating effect and LED street lamp.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is further described below, this embodiment only is used to explain the utility model, does not constitute the qualification of the utility model protection domain.
As shown in Figure 1: a kind of novel thin film circuit LED heat radiating device of road lamp of the utility model comprises shell 1, LED lamp pearl 2; Film circuit board 4, aluminium radiator 8, the pin 3 of said LED lamp pearl 2 both sides is welded on the film circuit board 4; Said aluminium radiator 8 upper surfaces are provided with the heat radiation point 7 of protrusion; Described film circuit board 4 all is fixedly mounted in the shell 1 with said aluminium radiator 8, and 7 upper surfaces plating one deck Copper Foil 6 is put in described heat radiation, and heat radiation point 7 and Copper Foil 6 are inserted in that circular hole corresponding on the film circuit board 45 is interior to become matched in clearance; The protrusion height of heat radiation point 7 and Copper Foil 6 and film circuit board 4 thickness coupling are so that film circuit board 4 is fitted with aluminium radiator 8.
During the enforcement of the utility model; The heat that LED lamp pearl 2 is produced passes to aluminium radiator 8 through Copper Foil 6 and heat radiation point 7, again through shell 1 and air exchange; Not only simple in structure, cost is low, and service life because of having reduced the heat transfer link, having improved radiating effect and LED street lamp.
