Abstract

A cooling fin-type lamp cup structure comprises a hollow cup body and a plurality of cooling fins; wherein, a space for containing a bulb is provided inside the cup body; the cooling fins are circularly arranged beside the outer edge of the cup body and extend along the axial direction of the cup body; each cooling fin faces one side of the cup body and is connected with the outer wall surface thereof and is curled at the tail end of the other side away from the cup body. By curing each cooling fin, the utility model has increased heat radiation area without increasing the occupation area of the lamp cup.

Description

Heat radiating fin chip Lamp cup structure

Technical field

The utility model relates to a kind of light fixture, relates in particular to a kind ofly can assemble Lamp cup bulb and that have radiating fin in it.

Background technology

Be used for all can having designed radiating fin usually so that heat radiation as the Lamp cup of golf calorific values such as Halogen lamp LED.A kind of like this heat abstractor of Lamp cup is disclosed in the prior art, it comprises radiating seat and Lamp cup, Lamp cup is placed in the radiating seat, and be used to assemble light-emitting device, as bulb etc., and be provided with the fin that a plurality of radiation are arranged outside this radiating seat, thereby the light-emitting device that can help to be assemblied in the Lamp cup dispels the heat.

Like this, because above-mentioned Lamp cup has the fin that a plurality of radiation are arranged outward, under the prerequisite of considering the Lamp cup size, the area of dissipation that can not at random increase each fin is with its radiating effect of further lifting, therefore, having produced the bulb with more high brightness and golf calorific value can't dispel the heat or problem such as radiating effect is not good by above-mentioned Lamp cup heat abstractor.

Therefore, need a kind of reasonable in design and effectively improve the Lamp cup structure of above-mentioned defective.

Summary of the invention

Main purpose of the present utility model is to provide a kind of heat radiating fin chip Lamp cup structure, and it further curls into position that each radiating fin extends the back and increased, and like this, not only can increase area of dissipation, but also can not make that glass lamp takies excessive space.

In order to achieve the above object, the utility model provides a kind of heat radiating fin chip Lamp cup structure, comprises hollow cup body and a plurality of radiating fin; Wherein, the inside of described cup body has the accommodation space of the bulb that is used to pack into, each radiating fin around being formed at outside the edge of glass body with arranging, and extend axially along the cup body, each radiating fin is connected towards a side of this glass body outside wall surface with the cup body, then is curling shape away from the end of the opposite side of cup body.

The utility model not only can increase area of dissipation, but also can not make that glass lamp takies excessive space.

The specific embodiment

In order to make those skilled in the art further understand feature of the present utility model and technology contents, see also followingly about detailed description of the present utility model and accompanying drawing, accompanying drawing only is used to provide reference and explanation, is not to be used for limiting the utility model.

With reference to figure 1, Fig. 2 and Fig. 3 is respectively three-dimensional exploded view, three-dimensional combination figure and the top plan view of the present utility model of the utility model and bulb.The utility model provides a kind of heat radiating fin chip Lamp cup structure, and in being used for being assemblied in for the bulb 2 as Halogen lamp LED etc., Lamp cup 1 comprises hollow cup body 10 and a plurality of radiating fin 11, wherein:

Cup body 10 be a cup, and its inside has accommodation space 100, and accommodation space 100 matches with bulb 2, is installed in the accommodation space 100 for bulb 2, and light that bulb 2 shines is throwed and goes out (promptly as shown in Figure 4).Cup body 10 contacts with bulb 2 at the inward flange wall of accommodation space 100, is transmitted on glass body 10 with the heat that bulb 2 is produced because of irradiation.

Radiating fin 11 is around being formed at outside the edge of glass body 10 with arranging, and extends axially along cup body 10, and its vertical view is radial (as shown in Figure 3).Each radiating fin 11 is connected towards a side of cup body 10 outside wall surface with cup body 10, is transmitted to heat on glass body 10 with further absorption bulb 2, again by each radiating fin 11 heat radiation; End away from the opposite side of cup body 10 then forms curling shape, increases the area of dissipation of each radiating fin 11 by the kenel of curling, and don't can make the shared space of Lamp cup 1 excessive because stretch out, and problem such as is difficult for thereby cause to install.

The utility model for embodiment in, the cup body 10 by the vicinity one lateral bending system of each radiating fin 11 after circular row constitute.Wherein, a lateral buckling of each radiating fin 11 has flanging 110, and each flanging 110 is curved, after arranging and engaging in regular turn, constitutes cup body 10, also forms accommodation space 100 simultaneously in each flanging 110.The number of turns that the opposite side of each radiating fin 11 curls can be decided according to radiating requirements; As shown in Figure 3, its curling multi-turn; And as shown in Figure 5, its number of turns then be one the circle or even less than a circle.

By above-mentioned contexture, can obtain heat radiating fin chip Lamp cup structure of the present utility model.

Use the utility model heat radiating fin chip Lamp cup structure, can behind cans, reach the increase area of dissipation, not cause a glass lamp to take effects such as excessive space again by increase each radiating fin 11 of area of dissipation because of extension.

The above is a preferred embodiment of the present utility model only, is not so promptly limits claim of the present utility model, and every other equivalence of being done in the utility model characteristic range changes or modifies, and all should be included in the claim of the present utility model.
