Abstract

The utility model discloses a radiator for an LED (Light-Emitting Diode) mining lamp. The radiator comprises a strut and an external radiating region surrounding the strut, a circle of radiating holes are arranged on the surface of the strut, an external radiating fin is arranged on the external radiating region, the radiator adopted can conduct inner-layer radiation and outer-layer radiation, thereby more reasonably utilizing the radiating space and being capable of greatly increasing the radiation area. In addition, an airflow channel is arranged on the radiating region, so that the radiation efficiency is improved; a concave radiating clearance is arranged on the airflow channel, vent holes can be communicated with the external radiating clearance after a lamp bead panel is installed well, heat can be carried away through air convection, and the service life of the LED lamp is prolonged.

Description

A kind of LED bulkhead lamp capable radiator

Technical field

The utility model relates to LED floodlight circuit technology, relates in particular to a kind of LED bulkhead lamp capable radiator.

Background technology

Bulkhead lamp capable commonly used has two kinds at present, a kind of is the bulb illumination, and this mode is thrown light on by single bulb, is the first generation product of industrial and mineral illumination, be in absolute leading position in a very long time, but consume energy high, brightness of illumination is looked into, service life is short and be eliminated gradually; Another kind then is the LED illumination, this mode adopts one or more led light sources to throw light on, has very strong illumination brightness, the advantages such as low, the long service life of consuming energy, but, the LED bulkhead lamp capable mainly adopts COB integrated optical source, there is hidden danger in the heat radiation of this light source always, radiator requirement to light fixture is very high, simultaneously, assembles because the driving power of light fixture is direct and radiator is fitted, cause the driving power temperature higher, thereby accelerated the electronic component aging speed of driving power, greatly shortened the life-span that drives, and then shortened the life-span of whole light fixture.

The natural convection radiator that adopts on the LED bulkhead lamp capable mostly is the heronsbill structure, this radiator is by the column structure of centre the heat energy of thermal source to be derived, again by around laminated structure with dissipation of heat in air, the light source that cooperates different capacity by the whole height of adjusting radiator comparatively is fit to the light source that heat generating spot is concentrated.But along with the increase of lamp power, caloric value improves greatly, even constantly increase the volume of radiator, radiating efficiency also can be more and more lower, can not satisfy the heat radiation requirement of large-power lamp, and the heatsink mass of this structure is larger, hangs when installing, and has certain potential safety hazard.

The utility model content

The purpose of this utility model is the problem that solves above-mentioned existence, provides that a kind of radiating effect is fast, simple in structure, a kind of LED bulkhead lamp capable radiator of good reliability.

The purpose of this utility model realizes as follows: a kind of LED bulkhead lamp capable radiator, and the outer radiating area that has pillar and be surrounded on pillar is provided with a circle louvre along described pillar surface, and described outer radiating area is to be provided with outer fin.

Further, described louvre is the chimney type structure.

Further, described outer loose sheet is to be become by the fin collar winding with " Y " type structure, is distributed with the heat radiation gap of concave structure between the described outer fin.

Advantage of the present utility model: the radiator that the utility model adopts is divided into inside and outside double-deck heat radiation, has more reasonably utilized heat-dissipating space, can significantly increase area of dissipation.Simultaneously be provided with gas channel at radiating area, improved radiating efficiency.

2, the heat radiation gap of concave structure between louvre and the outside heat sink makes lamp pearl plate install rear louvre and still can walk heat by groove and extraneous air generation convective zone, has prolonged the service life of LED light fixture.

Description of drawings

Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings

Fig. 1 is structural representation of the present utility model;

Reference numeral: 1, pillar, 2, outer radiating area, 3, louvre, 21, outer fin, 22, the heat radiation gap.

The specific embodiment:

As shown in Figure 1, a kind of LED bulkhead lamp capable radiator, the outer radiating area 2 that has pillar 1 and be surrounded on pillar 1, its pillar 1 is higher than the height of outer radiating area 2.Be provided with a circle along described pillar 1 surface and have chimney type structure louvre 3, described outer radiating area 2 is to be provided with outer fin 21; Described outer loose sheet 21 is to be become by the fin collar winding with " Y " type structure, is distributed with the heat radiation gap 22 of concave structure between the described outer fin 21.

Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
