Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, and propose a kind of LED street lamp with integrated radiating structure, this LED street lamp has good radiating effect.
The purpose of this utility model realizes by following technical proposal: a kind of LED street lamp with integrated radiating structure, comprise housing, several LED chip plates and several lens, in described housing, electrically-controlled component is installed, described LED chip plate is electrically connected with electrically-controlled component, it is characterized in that, described housing forward end has a heat sink extended forward, described LED chip plate is arranged on the lower surface of heat sink, described lens and LED chip plate one_to_one corresponding, and lens cover on LED chip plate, the upper surface of described heat sink has several fin, described fin, heat sink and housing are the integral structure that aluminum is made.
In the technical program, fin, heat sink and housing are integral type structure, the electrically-controlled component being built in enclosure interior comprises the parts such as sensor, delay switch, voltage-stablizer, heat that electrically-controlled component produces also can be distributed by heat sink and fin, in addition LED chip plate is connected directly between on the lower surface of heat sink, and radiating effect is better.
Have in the LED street lamp of integrated radiating structure above-mentioned, the rear end of described heat sink has some air vents running through type.Air vent vertically runs through the plate face of heat sink, is conducive to ventilation and heat.
Have in the LED street lamp of integrated radiating structure above-mentioned, described fin is vertically connected on heat sink, and the spacing between each fin is all equal.Evenly, result of ventilating heat dissipation is good for vertical setting and the equal fin heat radiation of spacing.
Have in the LED street lamp of integrated radiating structure above-mentioned, described fin is made as strip, and the upper edge of fin is curved, the rear end, upper edge of described fin flushes with the upper edge of housing forward end, and the front end, upper edge of fin and the front of heat sink are along flushing.Fin flushes with the edge of housing and heat sink respectively, and fin arranges along the length direction of housing and heat sink is marked off several heat dissipation cavity, increasing heat radiation area and result of ventilating heat dissipation is better.
Have in the LED street lamp of integrated radiating structure above-mentioned, described LED chip plate is strip rectangular slab, and the length direction of LED chip plate and the setting direction of fin perpendicular.Fin is arranged with LED chip plate is mutually vertical, and the heat that LED chip plate can be made to produce is distributed faster.
Have in the LED street lamp of integrated radiating structure above-mentioned, the thickness of described fin is 2mm ~ 5mm, and the distance between adjacent two fin is 8cm ~ 20cm.Distance between the thickness of fin and adjacent two fin all has influence on radiating effect, is also associated with the overall size dimension of housing simultaneously.
Compared with prior art, the utility model has the following advantages:
1, because fin, heat sink and housing all adopt aluminum to make, aluminum has good heat conductivility, and is designed by integrative-structure, the heat on housing can fast, seamless delivery is on fin, heat is avoided to assemble on housing and heat sink, good heat dissipation effect.
2, because heat sink collects the heat having electrically-controlled component and LED chip plate to produce near electrically-controlled component one end, therefore the fin height at this place is higher, flush with the upper edge of housing forward end, the fin at this place is made to have larger area of dissipation, and away from the heat that electrically-controlled component one end produces owing to only having LED chip plate, therefore the fin height at this place reduces gradually, reduces the overall volume of housing, has taken into account the overall size dimension of radiating effect and housing.
