Abstract

The utility model relates to a radiator of an LED (light-emitting-diode) bulb lamp, which comprises a body and a radiating platform, wherein the body is in a frustum-shaped hollow structure and is provided with a side wall and a larger annular end face, and the radiating platform is matched with the larger annular end face of the body, is arranged in the inner ring of the larger annular end face and is higher than the periphery. The radiator is made of high heat conductivity aluminum alloy and adopts a high radiating platform structure, and upper windows and lower windows of the radiator adopt a passive natural thermal convection design, so that the whole LED bulb lamp has a higher radiating effect, and the structure is optimized and simplified, thereby reducing the size and lowering the cost; besides, with the novel six-petal appearance, the radiator looks more beautiful.

Description

LED bulb lamp radiator

Technical field

The utility model relates to a kind of LED bulb lamp radiator.

Background technology

The LED bulb lamp is the novel energy-conserving light fixture that substitutes the conventional incandescent bulb, and becomes the only choosing of novel green illumination gradually along with the technological high speed development LED of LED throws light on.Yet one of them key factor that influences LED light fixture quality is heat radiation; The heat accumulative total of LED light fixture not only influences the electric property of LED; Also possibly finally cause LED to lose efficacy, therefore, in order to guarantee the life-span of LED light fixture; Heat radiation becomes the key technology that white light LEDs is used, and the heat that minimizing or rapid dissipation LED produce becomes the matter of utmost importance of white light LEDs aspect Application Design.

So following improvement technology occurred to LED bulb lamp radiator structure: the mount pad as at the LED bulb lamp connects fin; This mount pad is established the fin inserting groove; Fin and inserting groove are realized interference fit so that the fin card ends in inserting groove through the mode of external pressurized, to reduce thermal resistance, enlarge contact area; Reach radiating effect, reduce the little and heat abstractor weight of volume simultaneously.Though this structure volume reduces to some extent, and is still not ideal enough.

In view of the shortcoming of above-mentioned prior art, to the further perfect necessity of still having of LED bulb lamp radiator structure.

Summary of the invention

Not good enough, the comparatively complicated problem that causes cost and volume to be difficult to reduce of structure of heat dispersion that the utility model exists in order to solve prior art, and propose a kind ofly can optimize heat dispersion and LED bulb lamp radiator simple in structure.

The utility model is realized through following scheme:

Above-mentioned LED bulb lamp radiator comprises body and cooling platform, and said body is the hollow structure that profile is frustum roughly, has sidewall and big annular end face; The big annular end face of said cooling platform and said body is complementary, and is positioned at the ring of this big annular end face, and around being higher than.

Described LED bulb lamp radiator, wherein: the said radiator structure that is formed in one, said body and said cooling platform are structure as a whole.

Described LED bulb lamp radiator, wherein: said sidewall is concave-convex shaping radially, forms to have a plurality of convexities and the groove that is uniformly distributed with vertically, and described convexity and groove are laid at interval; The inboard of said convexity be recessed to form heat dissipation channel, the two ends of said groove are shorter than convexity slightly, form window.Said sidewall is six valve structures.

Described LED bulb lamp radiator, wherein: have a plurality of pilot holes on the said cooling platform.

Beneficial effect:

The LED bulb lamp heat sink applications of the utility model is in energy-saving LED ball bubble type lamp, and body is the important component part of whole bulb lamp outward appearance, also is the LED radiator simultaneously; Material adopts the high thermal conductivity aluminium alloy, adopts high cooling platform structure, utilizes the radiator passive Natural Heat Convection design of window up and down simultaneously; Make the heat radiation of whole lamp more efficient; Structure also is able to optimize simultaneously, and is more simple, reduced cost thereby reduced volume; Six novel lobe profiles make outward appearance have more aesthetic feeling.

Description of drawings

Fig. 1 is the stereogram of the LED bulb lamp radiator of the utility model;

Fig. 2 is another visual angle stereogram of the LED bulb lamp radiator of the utility model.

The specific embodiment

Like Fig. 1, shown in Figure 2, the LED bulb lamp radiator of the utility model structure that is formed in one has body 1 and cooling platform 2.

Body 1 is integrated hollow structure, and profile is frustum roughly, has sidewall 11 and big annular end face 12;

Sidewall 11 is concave-convex shaping radially, forms to have a plurality of protruding 111 and the groove 112 that is uniformly distributed with vertically, and convexity 111 is laid with groove 112 at interval; It is protruding 111 that the protruding 111 inboard heat dissipation channels that are recessed to form, the two ends of groove 112 are shorter than slightly, forms window 113,114; Utilize this window 113,114, form cross-ventilation, realize heat radiation with this convexity 111 and groove 112.

What in the present embodiment, this sidewall 11 was selected is six valve structures.

The material of body 1 adopts the aluminium of high thermal conductivity.Body 1 is the important component part of whole bulb lamp outward appearance, also is the thermal component of whole bulb lamp, is used for fixing light source, aluminium base, a plurality of parts such as lampshade screw socket glue spare.

Cooling platform 2 is complementary with body 1 big annular end face 12, and is positioned at the ring of this big annular end face 12, and is one-body molded with body 1, and around being higher than.Have a plurality of screw pilot holes on the cooling platform 2, be used to install the aluminium base of different size, and some hole wherein is used for through power line.Design around this cooling platform 2 is higher than is conveniently carried out secondary operations to the plane of platform, and flatness can be controlled less than 0.02mm, and cooling platform is contacted with led module fully, in time conducts led module and produces heat, prolongs LED service life.

The heat exchange pattern of this radiator is through cooling platform 2 heat of led die to be transmitted to body 1, through 1 heat radiation of aluminium alloy body, utilizes window 113,114 up and down simultaneously, makes full use of cross-ventilation and dispels the heat.

This heat sink applications is in energy-saving LED ball bubble type lamp, and body is the important component part of whole bulb lamp outward appearance, also is the LED radiator simultaneously; Material adopts the high thermal conductivity aluminium alloy, adopts high cooling platform structure, utilizes the radiator passive Natural Heat Convection design of window up and down simultaneously; Make the heat radiation of whole lamp more efficient; Structure also is able to optimize simultaneously, and is more simple, reduced cost thereby reduced volume; Six novel lobe profiles make outward appearance have more aesthetic feeling.

The protection domain of non-so limitation the utility model so use the equivalence techniques variation that the utility model specification and diagramatic content do such as, all is contained in the protection domain of the utility model.
