Abstract

The invention discloses a novel heat radiating device with a thin film circuit for a light emitting diode (LED) street lamp. The novel heat radiating device comprises a housing, an LED lamp bead, a thin film circuit board and an aluminum heat radiator, wherein pins on the two sides of the LED lamp bead are welded on the thin film circuit board; a protruding heat radiating point is formed on the upper surface of the aluminum heat radiator; the thin film circuit board is stuck to a flat surface of the aluminum heat radiator; the aluminum heat radiator is fixedly mounted in the housing; and a layer of copper coil is plated on the upper surface of the heat radiating point of the aluminum heat radiator. The novel heat radiating device has the advantages that the structure is simple, the cost is low, and a heat transfer link of heat produced when the LED lamp bead works can be further reduced, so as to improve the heat radiating effect and prolong the service life of the LED street lamp.

Description

A kind of novel thin film circuit LED heat radiating device of road lamp
Technical field
The present invention relates to LED street lamp field, relate 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, technical scheme of the present invention 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, technical scheme of the present invention 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.
Further improvement of the present invention 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 invention has the beneficial effects as follows: 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 a structural representation of the present invention.
The specific embodiment
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is further described below, this embodiment only is used to explain the present invention, does not constitute the qualification of protection domain of the present invention.
As shown in Figure 1: a kind of novel thin film circuit LED heat radiating device of road lamp of the present invention 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 enforcement of the present invention; 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.
