Description

A kind of LED shot-light and radiator structure thereof

Technical field

The utility model relates to the LED lighting apparatus, more specifically, relates to a kind of LED shot-light and radiator structure thereof.

Background technology

The LED shot-light is the illuminations that has extensively adopted at present, has advantages such as low power consumption, high light efficiency, safety, environmental protection.Practice shows that the quality of LED shot-light heat dispersion is very big to its influence in service life.Therefore, existing LED shot-light generally is equipped with radiator structure.

Yet the radiator structure that present LED shot-light adopts usually comprises following several: 1. make the heronsbill structure with the stretching aluminium section bar, because the process limitation of aluminium section bar need be carried out the profile that car is made shot-light again, processing link is more.And when the shot-light horizontal positioned, thermal convection current effect extreme difference is unfavorable for heat radiation.2. use the die casting one-shot forming, owing to the die-casting material reason, the thermal conductivity factor of die casting aluminium can be than low a times of stretching aluminium, promptly the thermal resistance of Chan Shenging can increase and is twice, baking vanish technology is used in the surface treatment of die casting aluminium usually, equal to wrap the very low paint vehicle of one deck thermal conductivity on the surface of radiator, can reduce with air contact heat radiation and heat loss through radiation effect.Therefore, the radiator structure that presses for existing LED shot-light improves.

The utility model content

At the deficiencies in the prior art, the utility model provides a kind of LED shot-light, and its radiator structure adopts the petal type fin of band hollow out, has improved the effect of heat loss through convection.

The LED shot-light that the utility model provides comprises: lamp socket, and the LED seat, the LED light-emitting component, lens, cover is characterized in that further comprising a plurality of nested each other petal type fin, described petal type fin all has openwork part.

Preferably, described petal type fin has the chassis, a plurality of heat radiation lobes and the openwork part between the lobe of respectively dispelling the heat.Further preferably, described chassis has perforation.

Preferably, outermost petal type fin engages the shell that forms shot-light with described cover.

Preferably, the thickness of described petal type fin is 0.6mm.

The utility model also provides a kind of radiator structure of LED shot-light, it is characterized in that described radiator structure comprises a plurality of nested each other petal type fin, and described petal type fin all has openwork part.

Preferably, outermost petal type fin engages the shell that forms shot-light with the cover of LED shot-light.

Preferably, the thickness of described petal type fin is 0.6mm.

A kind of LED shot-light of the present utility model and radiator structure thereof adopt the petal type fin of band hollow out, have increased effective area of dissipation, have improved the effect of heat loss through convection, make easily, and economical with materials, and can make the LED shot-light more both artistic and practical.

The specific embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with the specific embodiment and conjunction with figs. are detailed.

Fig. 1 is the LED shot-light of the utility model embodiment and the decomposition chart of radiator structure thereof.LED shot-light of the present utility model comprises lamp socket 1, petal type fin 2, petal type fin 3, petal type fin 4, petal type fin 5, LED seat 6, LED light-emitting component 7, lens 8 and cover 9.Wherein lamp socket 1, LED seat 6, LED light-emitting component 7, lens 8 and cover 9 are the common structure in the existing LED shot-light.The utility model mainly improves the radiator structure that is the LED shot-light.

In the middle of embodiment of the present utility model, the radiator structure of LED shot-light comprises a plurality of nested each other petal type fin 2-5.Figure 1 illustrates from outside to inside totally four petal type fin, those skilled in the art also can adopt other quantity as required certainly.The structure of each petal type fin 2-5 comprises the chassis, a plurality of heat radiation lobes and the openwork part between the lobe of respectively dispelling the heat, for example the chassis 3a of the petal type fin 3 among Fig. 1, heat radiation lobe 3b and the openwork part 3c between the lobe of respectively dispelling the heat.The chassis of each petal type fin has perforation, is used for lead and passes.Openwork part can improve the heat loss through convection effect, has improved radiation stability, particularly is under level, inclination, the different laying states such as vertical at the LED shot-light, can reach same heat loss through convection effect.The end of outermost petal type fin 2 has the joint portion 2a with cover 9, and joint portion 2a is provided with structures such as screw thread or bayonet socket, thereby engages the shell that forms shot-light with described cover 9.

Fig. 2-4 shows the schematic perspective view after the assembling of LED shot-light, and the petal type fin nests together and is superimposed as the flower profile, not only helps heat radiation, and profile is also more attractive in appearance.Further, fin can form different colours through oxidation processes, has strengthened the decorative effect of light fixture.The petal type fin can adopt the punching press aluminium to make thickness 0.66mm.Sheet Metal Forming Technology working (machining) efficiency height, and reduced the aluminium use amount, reduced product cost.

To sum up, LED shot-light of the present utility model has improved the radiator structure of traditional LED shot-light with the petal type fin of band hollow out, has increased effective area of dissipation, has improved the effect of heat loss through convection, and have easy manufacturing, economical with materials, advantages such as good looking appearance practicality.

The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
