Abstract
The utility model relates to a high-power LED illumination device with dustproof function, which comprises a LED chip, a connecting wire, a cathode, a lens, a cooling fin and an external encapsulation. The cooling fin is provided with a self-cleaning layer. The utility model uses the lotus leaf effect in bionics so that the cooling fin has the self-cleaning function, the influence of dust and rain water on cooling performance is effectively prevented and consequently the service life of products can be prolonged and the use cost is reduced.
Description
Technical field
The utility model relates to a kind of LED lighting apparatus, particularly relates to a kind of high-power LED illuminating device with dust reduction capability.
Background technology
In recent years, high-power LED (light emitting diode) lighting equipment is based on the advantage at aspects such as energy-conservation, efficient, environmental protection, obtains application more and more widely and constantly improves.And 80% be converted to heat energy owing to have an appointment in the electric energy that consumed of LED luminaire, therefore, improving heat dispersion is the technical essential of LED lighting device, especially for high-power LED illuminating device, and the good and bad luminosity attenuation rate and the service life that directly influences device of heat dissipation design.
See also Fig. 1, shown in Figure 2, be existing a kind of high-power LED (light emitting diode) lighting equipment, it mainly is made up of led chip 1, connecting line 2, negative electrode 3, lens 4, fin 5 and outer package 6.Wherein fin 5 adopts Natural Heat Convection, has advantages such as cooling system is simple, reliability is high, long service life, noiselessness.But, because fin is exposed in the environment, adhere to dust, rainwater etc. easily, therefore, the long-time back radiating effect that uses reduces, and has also therefore shortened the service life of lighting apparatus.
This shows that above-mentioned existing high-power LED illuminating device obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.How to found a kind of good heat dissipation effect, long service life and the high-power LED illuminating device with dust reduction capability waterproof, the dustproof new structure, the current industry utmost point of real genus needs improved target.
The utility model content
The technical problems to be solved in the utility model provides a kind of high-power LED illuminating device with dust reduction capability, makes its good heat dissipation effect, long service life and waterproof, dustproof, thereby overcomes the deficiency of existing high-power LED illuminating device.
For solving the problems of the technologies described above, the utlity model has the high-power LED illuminating device of dust reduction capability, comprise led chip, connecting line, negative electrode, lens, fin and outer package, described fin is provided with the automatically cleaning layer.
As a kind of improvement of the present utility model, described automatically cleaning layer is micron or nano particle sprayed coating.
Described automatically cleaning layer is surface treated super-hydrophobic layer.
After adopting such design, the utility model utilizes the lotus leaf effect in the bionics, makes fin have self-cleaning function, effectively prevents the influence to heat dispersion of dust, rainwater, thereby can prolong service life of product, reduces use cost.
Description of drawings
Above-mentioned only is the general introduction of technical solutions of the utility model, and for can clearer understanding technological means of the present utility model, the utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment.
Fig. 1 is the structural representation of existing high-power LED illuminating device.
Fig. 2 is the cutaway view of Fig. 1.
Fig. 3 is a kind of heat radiating fin structure schematic diagram with high-power LED illuminating device of dust reduction capability of the utility model.
The specific embodiment
See also shown in Figure 3ly, a kind of high-power LED illuminating device with dust reduction capability of the utility model comprises led chip 1, connecting line 2, negative electrode 3, lens 4, fin 5 and outer package 6, and has set up automatically cleaning layer 51 on the outer surface of fin 5.This automatically cleaning layer 51 can be surface treated super-hydrophobic layer, also can be the sprayed coating of hydrophobic micron or nano particle.
Find after deliberation, lotus leaf all has more coarse surface than other blades, feather than other furs, thereby make the globule that is positioned on lotus leaf, the feather have bigger contact angle, the globule can roll on lotus leaf blade or feather, not only take away surperficial dust, also can not stay stain.The utility model utilize exactly process for treating surface or the micron, the nano-spray technology, make fin surface have micron order even the nanoscale projection similar with lotus leaf, thereby can avoid dust attached on the spreader surface, even spreader surface has speckled with small amount of dust, also can be pulled away with dew or raindrop.
The fin of high-power LED illuminating device that the utlity model has dust reduction capability is according to bionics principle, utilized lotus leaf effect, make fin have self-cleaning function, radiating efficiency is higher, stability is better, be beneficial to the service life that prolongs lighting apparatus, is suitable for extensively promoting the use of.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in the protection domain of the present utility model.
