The specific embodiment
Below in conjunction with the drawings and specific embodiments, embodiment of the present utility model is elaborated.
Contrast accompanying drawing, a kind of LED Projecting Lamp circulation radiating structural design, its structure is as passing through U-shaped support 13 fixedly left plate 9, right plate 10 on the dual-side of the heat radiation module 3 of main structure body; The front of heat radiation module 3 is provided with some groups of LED luminescence components 2; Power supply module 6 is fixed on upper cover plate 8 inner sides; Front lens 1 is arranged on the dead ahead of LED luminescence component; Inter panel 7, upper cover plate 8 are mounted on heat radiation module 3 by draw-in groove successively and form the whole cavity of Projecting Lamp below; Fan 4, circulation dividing plate 5 be arranged on heat radiation module 3 after, 6 of the heat radiation module 3 in Projecting Lamp cavity and power supply modules separate by circulation dividing plate 5 and leave air-flow through hole 14 for making air-flow that fan the produces heat radiation module 3 of flowing through smoothly; On left plate 9, right plate 10, all leave ventilating opening 11, lower ventilating opening 12.
On described upper cover plate 8, establish connection line,
Some groups of described LED luminescence components 2 are located on heat radiation module 3 and are electrically connected to power supply module 6.
Described heat radiation module comprises heat-radiating substrate and radiating fin.
Described power supply module is positioned at whole lamp cavity and is fixed on upper cover plate inner side, and and the radiating fin of heat radiation module between leave space.
Described fan is mounted on the place, space between power supply module and radiating fin, can carry out forced convertion heat radiation to heat radiation module, produces the power of whole circulation.
Between described fan and radiating fin, there is circulation dividing plate, and on circulation dividing plate, have air-flow through hole 14 for making electric fan air port gas flow to smoothly heat radiation module.
Described fan can be parallel shape and places up and down with heat radiation module, saves space, is beneficial to the later stage to install and use, but do not get rid of fan, is not other modes of emplacement with heat radiation module.
Left and right side plate is equipped with in Projecting Lamp both sides, is equipped with upper vent hole and lower passage on left and right side plate, and two passages play respectively air inlet and air outlet, make Projecting Lamp internal cavity air-flow and the external world be connected to form respectively circulation.
By the effect of circulation dividing plate, in conjunction with the ventilating opening on left and right side plate, in the inner circulation effect that produces of lamp body, make power supply module, heat radiation module all well on gas channel, strengthened the effect of fan forced convection heat radiation.
In order to make the integral heat sink effect of Projecting Lamp better, at heat radiation module 3, being added with fan 4 carries out forced convertion heat radiation below, if but only have fan, easily there is whirlpool shape in the air-flow in whole cavity, be difficult to the inner heat that produces of whole lamp to take away smoothly, if by fan with dispel the heat that module is vertical to be placed, air-flow can be easy to flow through radiating fin and reach radiating effect, but it is larger that such placement can make whole Projecting Lamp take up room, be unfavorable for installing and using of later stage.For head it off, fan is to parallel shape with heat radiation module to be placed up and down, make to take up room and greatly reduce, between fan and heat radiation module, add circulation dividing plate, cavity is divided into two-layer up and down, fan blows upper strata air-flow and enters heat radiation module district by circulation dividing plate overdraught through hole, afterwards by left, lower ventilating opening 12 on right plate flows out to surrounding environment, because making the air pressure of top regions, fan effect reduces, ambient atmosphere is by left, upper ventilating opening 11 on right plate enters cavity, so just, formed from a left side, ventilating opening air inlet on right plate, from a left side, the whole circulation channel that under right plate, ventilating opening is given vent to anger.In the situation that fan is parallel shape and places up and down with heat radiation module, both reduce whole lamp body long-pending like this, saved space, reached again the object that increases radiating effect.
The heat radiation module of fan, power supply module and luminescence component lays respectively at circulation dividing plate both sides, by the effect of circulation dividing plate, in conjunction with the ventilating opening on left and right side plate, make air-flow produce circulation effect, make power supply module, heat radiation module all well on gas channel, strengthened the effect of fan forced convection heat radiation.
After heat radiation module, be added with fan and carry out forced convertion heat radiation, fan can be parallel shape with heat radiation module and place up and down, between fan and heat radiation module, add circulation dividing plate, cavity is divided into two-layer up and down, fan blow upper strata air-flow by circulation dividing plate overdraught through hole enter heat radiation module district, after by the lower ventilating opening on left and right side plate, flow out to surrounding environment; Because fan effect makes the air pressure of top regions, reduce, ambient atmosphere enters cavity upper strata by the upper ventilating opening on left and right side plate, has so just formed ventilating opening air inlet from left and right side plate, the whole circulation channel that ventilating opening is given vent to anger from left and right side plate.
The above; it is only a specific embodiment of the present utility model; not the utility model to be done to the restriction of other form; common variation and the replacement for those skilled in the art, within the scope of technical scheme, carried out; do not departing under the prerequisite of the utility model creation design, any improvement of making all should be included in protection domain of the present utility model.
