Description
Technical field
The utility model relates to LED lamp technical field, is specifically related to a kind of LED bay light.
Background technology
LED bay light is a kind of lighting apparatus that mining industry is commonly used, and existing bulkhead lamp capable adopts solid aluminium or phase-change heat transfer technology to realize the heat radiation of lamp holder.Feature due to bulkhead lamp capable is that light source area is smaller, so thermal source is more concentrated.Facts have proved, solid aluminium is for the power of more than 200W, completely helpless, though lengthen radiator length for heat distribute do not play a part yet large.And Phase cooling, although can effectively conduct heat to radiator outer surface.But cost is high, processed complex.Which limits the power upper limit that in LED bay light, lamp holder can be selected, cause illumination not enough.
Utility model content
For solving the problem, the utility model provides a kind of LED bay light.
Concrete technical scheme of the present utility model is as follows:
A kind of LED bay light, comprises lampshade, lamp holder, heat radiation hollow profile, air inducing fan, ventilating duct and heat dissipation tank; Described heat radiation hollow profile one end connects lamp holder, the other end connects air inducing fan; Described ventilating duct one end connects air inducing fan, other end opening; Described heat dissipation tank is seal case, and described heat radiation hollow profile, air inducing fan and ventilating duct are positioned at heat dissipation tank inside.
By adopting this technical scheme: the heat conduction produced during lamp holder work is on heat radiation hollow profile, simultaneously, air inducing fan unlatching work, drawing airflow guiding blows above heat radiation hollow profile by ventilating duct, accelerated heat is spread to four limits by the hollow profile that dispels the heat, and is finally diffused in extraneous air by the heat transfer of the outer wall of heat dissipation tank.Meanwhile, the thermal air current that heat is formed in four limit diffusion processes by the hollow profile that dispels the heat progressively cools at uphill process and finally gets back in ventilating duct and blows to heat radiation hollow profile, forms optimum empty airflow circulating.Because the thermal conductivity factor of moving air is far above still air, ensure that the radiating rate of heat radiation hollow profile, thus make this LED bay light can select the lamp holder that power is higher.Meanwhile, adopt heat radiation hollow profile compared to traditional solid aluminium, bring the technique effect that lamp body overall weight alleviates, cost declines.
Preferably in above-mentioned LED bay light, described heat radiation hollow profile is provided with equally distributed detent projection.
By adopting this technical scheme: the contact area increasing heat radiation hollow profile and lamp holder, ensure that heat is transmitted to the speed on heat radiation hollow profile by lamp holder, increase the contact area of heat radiation hollow profile and air simultaneously, ensure the speed that heat is spread to surrounding by the hollow profile that dispels the heat.
It is further preferred that in above-mentioned LED bay light, described heat radiation hollow profile comprises and multiple section bar wall scroll, described each section bar wall scroll is all provided with the tenon portion and fourth of the twelve Earthly Branches portion that shape adapts, and each section bar wall scroll is combined by described tenon portion and fourth of the twelve Earthly Branches portion tenon.
By adopting this technical scheme: little mould can be adopted the machine-shaping of section bar wall scroll.Overcome the restriction of the mould tooth density existing for large Mould Machining, make the outer unload of section bar wall scroll very convenient, ensured that the contact external surface area of heat radiation hollow profile and air maximizes.
Compared with prior art, the utility model structure is simple, easy to prepare, alleviates the overall weight of light fixture, significantly reduces assembly cost, improve the power upper limit of light fixture, ensure that service life.

Detailed description of the invention
In order to be illustrated more clearly in the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further described.
Embodiment 1 of the present utility model as Figure 1-5:
A kind of LED bay light, comprises lampshade 1, lamp holder 2, heat radiation hollow profile 3, air inducing fan 4, ventilating duct 5 and heat dissipation tank 6; Described heat radiation hollow profile 3 comprises and multiple section bar wall scroll 32, described each section bar wall scroll 32 is all provided with the tenon portion 321 and fourth of the twelve Earthly Branches portion 322 that shape adapts.Each section bar wall scroll 32 by tenon portion 321 and fourth of the twelve Earthly Branches portion 322 each other tenon close and form.Shaping heat radiation hollow profile 3 is provided with equally distributed detent projection 31.Described heat radiation hollow profile 3 one end connects lamp holder 2, the other end connects air inducing fan 4; Described ventilating duct 5 one end connects air inducing fan 4, other end opening; Described heat dissipation tank 6 is the casing of sealing, and it is inner that described heat radiation hollow profile 3, air inducing fan 4 and ventilating duct 5 are positioned at heat dissipation tank 6.
In practice: the heat conduction produced when lamp holder 2 works is on heat radiation hollow profile 3, simultaneously, work opened by air inducing fan 4, drawing airflow guiding blows above heat radiation hollow profile 3 by ventilating duct 5, accelerated heat is spread to four limits by the hollow profile 3 that dispels the heat, and is diffused in extraneous air by the heat transfer of the outer wall of heat dissipation tank 6.Meanwhile, the thermal air current that heat is formed in four limit diffusion processes by the hollow profile 3 that dispels the heat progressively cools in uphill process, finally gets back in ventilating duct 5 and blows to heat radiation hollow profile 3, forms optimum cross-ventilation circulation.
After testing, its weight of the LED bay light of above-described embodiment 1 is only the 50%-60% of ordinary lamp and lantern, significantly alleviates the heavy burden of industrial and mineral.When adopting the lamp holder of 200W power, the material cost of embodiment 1 is only and adopts 60% of solid aluminium radiator, for adopting 35% of phase-change heat sink cost; When adopting the lamp holder of 300w power, the material cost being only embodiment 1 is only 25% of phase-change heat sink cost.And adopting the structure of embodiment 1, the power upper limit of lamp holder more can break through to 500w.And the LED bay light on existing market, its lamp holder power upper limit is only 300w.
The above; be only specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; the technical staff of any skilled is in technical scope disclosed in the utility model; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with the protection domain of claims.
