Abstract

The utility model discloses a heat conducting lampshade of a bulb lamp. The lampshade comprises a metal support and a plurality of shade sheets; each shade sheet is formed by injection molding; a plurality of shade sheets are lapped on the metal support and spliced into the lampshade; and the outer edge of the metal support is exposed. According to the heat conducting lampshade of the bulb lamp, a heat dissipation function is realized through the exposed outer edge of the metal support, and the service life of the bulb lamp can be prolonged; a plurality of shade sheets are spliced into the complete lampshade, and the size and the thickness of each shade sheet can be accurately controlled by injection molding due to certain size of an injection mold, so that the lampshade is small in size error, uniform in thickness and high in light transmission rate; and the hemispheric lampshade can be easily obtained by injection molding, and the irradiation angle of the hemispheric lampshade is large, so that the quality of the lampshade is greatly improved.

Description

But a kind of bulb lamp lampshade of heat conduction

Technical field

The utility model relates to a kind of bulb lamp lampshade, but particularly relates to a kind of bulb lamp lampshade of heat conduction.

Background technology

The lampshade of existing LED bulb lamp adopts all-in-one-piece structure usually, and the radiating effect of all-in-one-piece lampshade is relatively poor, causes the life-span of LED bulb lamp shorter.

The utility model content

In view of this, but the purpose of this utility model is to provide a kind of bulb lamp lampshade with heat conduction of good heat radiating function.

In order to reach above-mentioned purpose, solution of the present utility model is:

But a kind of bulb lamp lampshade of heat conduction comprises metallic support and multi-disc cover sheet, and each covers the cover sheet that sheet is injection mo(u)lding, and multi-disc cover sheet rides on the metallic support and is spliced into lampshade, and the outer edge of metallic support is exposed outside.

Described cover sheet is two.

Described cover sheet is three.

Lampshade is divided into two described cover sheets, and described metallic support is the arc chip architecture with two legs.

Lampshade is divided into three described cover sheets, and described metallic support has the leg of three arc sheets.

Described metallic support is the metallic support of aluminum.

Lampshade is more than half globe holders.

After adopting said structure, but the bulb lamp lampshade of a kind of heat conduction of the present utility model has following beneficial effect: realize heat sinking function by the outer edge that metallic support is exposed, can prolong the service life of bulb lamp; And a plurality of cover sheets are combined into a complete lampshade, because the size of injection mold is certain, can accurately control size and the thickness of each cover sheet by injection mo(u)lding, thereby obtain that scale error is little, even thickness, light transmittance be higher; And can be easy to obtain more than half globe holders by injection mo(u)lding, the irradiating angle of more than half globe holders is larger, has greatly improved the quality of lampshade.

But Fig. 1 is the assembling schematic diagram of the bulb lamp lampshade of a kind of heat conduction of the present utility model;

But Fig. 2 is the decomposing schematic representation of the bulb lamp lampshade of a kind of heat conduction of the present utility model.

Cover sheet 1

Metallic support 2

The specific embodiment

In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.

Shown in Fig. 1 to 2, but the bulb lamp lampshade of a kind of heat conduction of the present utility model comprises multi-disc cover sheet 1, and metallic support 2.

Lampshade is more than half globe holders, and it rides on the metallic support 2 by multi-disc cover sheet 1 and is spliced, and the bottom that connects back cover sheet 1 and metallic support 2 respectively correspondence is installed on the lamp socket, and the outer edge of metallic support 2 is exposed outside.Preferably, metallic support 2 is aluminum products, and is so both light, is easy to again heat radiation, and then prolongs the service life of bulb lamp.Each covers sheet 1 and adopts injection mo(u)lding, can it is divided into two, three or four cover sheets 1 according to the large young pathbreaker of lampshade.

As a preferred embodiment of the present utility model, lampshade is divided into two cover sheets 1, and metallic support 2 be convenient to like this install, and cost is low for to have the arc chip architecture of two legs.

As an again preferred embodiment of the present utility model, lampshade is divided into three cover sheets 1, and metallic support 2 has the leg of three arc sheets, leg can be integral type, also can be split typely, as shown in Figure 2, the top of three legs links together by buckle structure and is three-pawl type.This structure can increase the area of dissipation of metallic support 2, accelerates heat radiation, prolongs the service life of bulb lamp.

And a plurality of cover sheets 1 are combined into a complete lampshade, because the size of injection mold is certain, can accurately control size and the thickness of each cover sheet 1 by injection mo(u)lding, thereby obtain that scale error is little, even thickness, light transmittance be higher; And can be easy to obtain more than half globe holders by injection mo(u)lding, the irradiating angle of more than half globe holders is larger, has greatly improved the quality of lampshade.

Above-described embodiment and accompanying drawing and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
