Description
Technical field:
The utility model relates to LED light fixture manufacturing technology field, is specifically related to a kind of LED light fixture high heat dispersion circuit board arrangement.
Background technology:
Under the background that Present Global energy starved worry raises once again, saving the energy is the important problem that we shall face future, at lighting field, the application of LED luminous product is just attracting common people's sight, LED has the many merits such as light efficiency is high, long service life, energy-saving and environmental protection, is more and more widely used in various fields.It is the new type light source of 21 century, has advantages of that efficiency is high, the life-span is long, the conventional light source such as cracky cannot not compare with it.While adding forward voltage, light-emitting diodes physical efficiency is sent monochrome, discontinuous light, and this is the one of electroluminescent effect.The chemical composition that changes the semi-conducting material adopting, can make light-emittingdiode be emitted near ultraviolet ray, visible ray or ultrared light.Due to LED, to make voltage low, can active illuminating and have certain brightness, and brightness can be used again voltage-regulation, shock-resistant, anti-vibration again itself, life-span are long, therefore play increasing application in demonstration field, especially utilized in fluorescent lamp field, there is the technological merit that brightness is high, the life-span is long.Circuit board all can be installed in LED light fixture; but the circuit board in some specific LED light fixture often can be damaged; and in LED light fixture, to hold flimsy be most exactly circuit arrangement; will bother very much once damage maintenance and change; and the most reasons that cause circuit board damage to be all circuit board overheated and burn out circuit, be therefore that LED industry is endeavoured the problem solving for the heat radiation of circuit board always.
Utility model content:
Technical problem to be solved in the utility model is to provide a kind of LED light fixture high heat dispersion circuit board arrangement stable, excellent radiation performance of installing.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
A kind of LED light fixture high heat dispersion circuit board arrangement, comprise shell, circuit board, induced-draught fan and cooling fan, described circuit board is arranged on the centre position of the inside of shell, portion and circuit board two ends connecting position are provided with spiral shell plate in the enclosure, described spiral shell plate is tightly fixed on by screw on the inwall at enclosure two ends, bottom in the left side of shell is provided with induced-draught fan, the air port of described induced-draught fan extends to the inside of shell, and the air port place of enclosure is unenclosed construction, induced-draught fan can be blown into rapidly enclosure by cold wind in carrying out air draught like this, like this cold wind in the enclosure portion up flow circuit board is dispelled the heat, on the top on shell right side, cooling fan is installed simultaneously, linking part and the outer casing inner wall of described cooling fan and shell flush, the object of cooling fan is installed is like this also for when induced-draught fan is from bottom by distinguished and admirable blowing into time, the cooling fan at top can be pumped by the very fast thermal current by enclosure outward, just the hot blast of enclosure being pumped away at any time and is delivered into cold wind by a circulation like this, thereby to ensure that the temperature of circuit board can not rise too high, ensure the normal work of circuit board.
The beneficial effects of the utility model are: simple in structure, reasonable in design, installation is stablized, excellent radiation performance, are of value to the service life of holding circuit plate prolongation circuit board.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Wherein: 1-shell; 2-circuit board; 3-spiral shell plate; 4-induced-draught fan; 5-cooling fan.
Detailed description of the invention:
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of LED light fixture high heat dispersion circuit board arrangement, comprise shell 1, circuit board 2, induced-draught fan 4 and cooling fan 5, described circuit board 2 is arranged on the centre position of the inside of shell 1, be provided with spiral shell plate 3 in shell 1 inside with circuit board 2 two ends connecting positions, described spiral shell plate 3 is tightly fixed on by screw on the inwall at shell 1 inner two ends, in the bottom in the left side of shell 1, induced-draught fan 4 is installed, the air port of described induced-draught fan 4 extends to the inside of shell 1, and the air port place of shell 1 inside is unenclosed construction, induced-draught fan 4 can be blown into cold wind rapidly shell 1 inside in carrying out air draught like this, cold wind can up flow circuit board 2 is dispelled the heat in shell 1 inside like this, on the top on shell 1 right side, cooling fan 5 is installed simultaneously, described cooling fan 5 flushes with linking part and shell 1 inwall of shell 1, the object of cooling fan 5 is installed is like this also for when induced-draught fan 3 is from bottom by distinguished and admirable blowing into time, the cooling fan 5 at top can be very fast the thermal current by shell 1 inside pump outward, just the hot blast of shell 1 inside being pumped away at any time and is delivered into cold wind by a circulation like this, thereby to ensure that the temperature of circuit board 2 can not rise too high, ensure the normal work of circuit board 2.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
