Description

A kind of cross-ventilation Combined LED illumination lamp

Technical field

The utility model is related to a kind of headlamps, and in particular to a kind of cross-ventilation Combined LED illumination lamp.

Background technology

With the development of LED illumination lamp science and technology, the illumination of novel energy-saving LED replacement typical high power has been inexorable trend, But the huge heat that LED illumination lamp generates when working, constrains the application range of high-power LED illuminating lamp, how to solve LED light The heat dissipation problem of tool is that LED illumination lamp is marched toward the key factor in high-power epoch.

The heat dissipation performance of LED lamp is contact area size by lamp body and air and the stream that air passes through lamp body radiator What speed was determined.Conventional lamp uses dorsal fin-form heat spreader structures, since bottom plate uses enclosed construction, dorsal fin air circulation performance Bad, cold air cannot be supplemented quickly, and hot-air is unable to Quick diffusing, to leverage the integral heat sink performance of lamps and lanterns.

Utility model content

The purpose of this utility model is to be directed to deficiency in the prior art, provides a kind of cross-ventilation combined LED illumination Lamp improves the heat dissipation performance of LED lamp.

To achieve the above object, the utility model discloses following technical solutions：

A kind of cross-ventilation Combined LED illumination lamp, is all made of heat radiation fin structure before and after LED lamp.

Further, front and back radiating fin is through-hole type structure.

Further, the light source part integration packaging LED lamp bead of the LED illumination lamp.

Further, the encapsulation LED lamp bead uses round convergent bowl.

Further, the attachment device being connect with other LED lamps is surrounded by LED lamp.

Further, the radiating fin of LED lamp front is shorter than the radiating fin at LED lamp rear portion.

Further, the lamp body is formed using ADC12 aluminum material die casting.

Further, the lampshade uses glass material.

Further, silica gel waterproof sealing gasket is equipped in the lampshade.

A kind of cross-ventilation Combined LED illumination lamp disclosed by the utility model, has the advantages that：

The utility model, using hot-air convection principle, accelerates the effect of heat transfer and heat dissipation, drop by changing radiator structure The low weight of lamps and lanterns, reduces the volume of lamps and lanterns, improves the heat dissipation performance of LED lamp.

Specific implementation mode

Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described Embodiment is only the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to The range of the utility model protection.

Refer to Fig. 1-Fig. 4.

As specific embodiment, to ensure that radiating efficiency, front and back radiating fin are through-hole type structure.

As specific embodiment, the light source part integration packaging LED lamp bead 1 of the LED illumination lamp, the encapsulation LED light Pearl 1 uses round convergent bowl, and the purpose is to aluminium alloy radiators to have more and air contact surfaces, increases the cold heat-exchange surface of air Product, is more conducive to heat dissipation effect.

As specific embodiment, the attachment device being connect with other LED lamps, attachment device are surrounded by LED lamp Can be mounting, magnetic suck or other forms.

As specific embodiment, the front radiating fin 2 of LED lamp is shorter than the rear portion radiating fin 3 of LED lamp.

As specific embodiment, the lamp body is formed using ADC12 aluminum material die casting, thermal coefficient：96.2 (W/m.K), Its intensity is high, and resistance to pressure is good, anticorrosion, and water resistance is excellent.

As specific embodiment, the lampshade uses glass material, is equipped with silica gel waterproof sealing gasket in the lampshade, reaches The purpose of water proof and dust proof.

Compared to the content introduced in background technology, the utility model utilizes hot-air convection original by changing radiator structure Reason accelerates the effect of heat transfer and heat dissipation, hot-air that can quickly move through through-hole convection current and distribute, and is more in line with cross-ventilation original Reason, the heat that central source generates can be transmitted to quickly through front and back fin and not survey, accelerate air and lamp radiator Flow velocity effectively raises the heat dissipation performance of lamps and lanterns.The weight for reducing lamps and lanterns reduces the volume of lamps and lanterns, has unit quick Merge, flexibly forms the LED illumination device of various different capacities.

In identical lamp power, radiated using traditional dorsal fin using the LED lamp ratio of front and back fin through-hole heat dissipation LED lamps cooling performance improve 30% or more, lamps and lanterns volume weight decline 30% or more, improve the performance of product, save Production cost.

The above is only the preferred embodiment of the utility model, rather than its limitations；Although should be pointed out that with reference to upper Each embodiment is stated the utility model is described in detail, it will be understood by those of ordinary skill in the art that, it still can be with It modifies to the technical solution recorded in the various embodiments described above, or which part or all technical features is equally replaced It changes；And these modifications and replacement, so that the essence of corresponding technical solution is detached from various embodiments of the utility model technical solution Range.
