Abstract

The utility model relates to an improvement for the concentration-light rice foam structure, comprising a lamp body, a vacant cavity arranged in the bulb body, and two connection feet arranged on the bulb body. The other end of the connection foot is inserted in to the vacant cavity of the bulb body and the filament is arranged in the bulb body; the front end of the bulb body is provided with a light-concentration body; the vacant cavity body is in the shape of a cylinder, the wall body of the outer circumference is generally of the same thickness, the front end surface is a plane, and the back end is provided with an internal convex body. The vacant cavity body of the utility model is small, the oxidation of the tungsten filament is slow after being vacuumized, and the service life is long; the raw materials consumed in production is relatively small; the back end of the vacant cavity body is internally convex, and the utility model can disperse the lights toward the cavity body, thereby reinforcing the light intensity sent by the light-concentration body; the utility model does not need arrange fixed bead between the connection feet in the vacant cavity.

Description

Light-gathering lamp bulb

Technical field

The utility model relates to a kind of normal lighting utensil, especially relates to a kind of improvement to miniature Light-gathering lamp bulb structure.

Background technology

Present employed lighting bulb, because cell-shell all is a printing opacity, thereby the light that bulb sends also scatters to the zone that does not extremely need light.This is undoubtedly the waste of the energy.In order to address this problem, people often take the whole bag of tricks, as add the method for lampshade, and promptly the inner surface at lampshade adds reflectorized material, owing to lampshade is exposed in the air, easily by contamination by dust.Thereby after a period of time, the reflecting power of reflectorized material will reduce greatly; Have the inwall at bulb to add the optically focused coating material again, but produce this series products cost height, specification requirement is high; " a kind of optically focused christmes lamp bulb " (patent No. is 02225849.3) by name that someone applies for, it comprises bulb, tungsten filament, Dumet wire, and Dumet wire one end connects tungsten filament, and the other end stretches out the bulb outside and makes leg, the top of bulb thickeies thin-walled glass, forms the optically focused head.This patent is made thickening especially with the head of traditional round head lamp bubble, after bulb is lighted, can make light produce the special light that light beam is concentrated through the round focal point of thickening, and brightness is doubled; Someone's name " bulb structure " (patent No. is 01270629.9) of applying for again, this patent is a kind of bulb structure, its structure mainly is that the top with the bulb glass shell is made as the end face with convex lens function, use and make the interior filament of shell when luminous, light can be penetrated the effect that produces optically focused from this end face, thereby provide bulb to obtain special decorative effect.Though, these two patents all reach the effect of optically focused to the improvement of conventional bulb, still, their bodily form is comparatively tall and thin, cavity in the foam is bigger, when being evacuated, remaining oxygen molecule is more relatively, and tungsten filament is easy to oxidation, simultaneously, it is more to produce the material that consumes, and production cost is higher, influences the bulk strength of bulb.

Summary of the invention

The utility model mainly is that solution existing in prior technology spotlight effect is very not good, and useful life is short, and raw materials consumption is big, the technical problem that the bulk strength of bulb is very not high, provide a kind of spotlight effect good, useful life is longer, the Light-gathering lamp bulb that production cost is lower.

It is very not high that the utility model also solves the interior luminous flux of existing in prior technology unit volume simultaneously, and economy is the technical problem of very good grade not.

The utility model also solves existing in prior technology simultaneously and installs unstablely, and fixedly the leg of bulb need be used the technical problem of fixing pearl etc.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: Light-gathering lamp bulb, it comprises lamp body and is located at its interior cavity, two leg thereon are set, in the cavity of the other end in lamp body inserts lamp body of described leg, and be provided with filament betwixt, and be provided with a condensing body at the leading section of described lamp body, described cavity body is cylindric, the wall body of its periphery is uniform thickness substantially, and its front end face is the plane, and its rear end is provided with interior convex body.Like this, promptly significantly reduced the material of making lamp body, improved the bulk strength of lamp body again, and can prolong the oxidized time of filament.

As preferably, the both sides, rear portion of described lamp body are provided with a flat partially body, and described filament is arranged on the lamp body by the transverse plane.Helping lamp body stably is installed on the lamp socket.

As preferably, the fore-and-aft clearance of described cavity body and the diameter ratio of cavity body are 0.6～1.2: 1.Filament closer is placed on the lamp body by the transverse plane.Help the focusing of light like this.

As preferably, the fore-and-aft clearance of described cavity body is 3mm-6mm; The spacing of described two leg is 1mm-2mm, and its end is crooked laterally, and filament provided thereon is curved.The volume of cavity body helps improving the useful life of bulb for a short time and saves the material of making bulb.

Therefore, the utlity model has rational in infrastructurely, cavity body is little, and after being evacuated, remaining oxygen molecule is less, thereby the tungsten filament oxidation is slow, long service life; Overall structure is less, and the raw material that consumed during production are less relatively; The rear end of cavity body is to convex, can be light to the cavity inscattering, and strengthened the intensity of the light launched through condensing body, and need not between leg in cavity fixedly characteristics such as pearl to be set.

Accompanying drawing 2 is another kind of cross-sectional view of the present utility model.

Embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment: Light-gathering lamp bulb comprises lamp body 1 and is located at its interior cavity body 7, two leg 5 thereon are set.The fore-and-aft clearance of described cavity body 7 is slightly less than the diameter of cavity body, and the fore-and-aft clearance of described cavity body 7 is 5mm; The spacing of described two leg is 1.5mm, its end is crooked laterally, filament provided thereon is curved, in the cavity body 7 of the other end in lamp body 1 insertion lamp body of described leg 5, and is provided with filament 3 betwixt, and described filament 3 is arranged on the lamp body by the transverse plane, and be provided with a condensing body 2 at the leading section of described lamp body 1, and described cavity body 7 is cylindric, and the wall body of its periphery is uniform thickness substantially, its front end face is the plane, and its rear end is provided with interior convex body 4 (referring to Fig. 1).The both sides, rear portion of described lamp body 1 are provided with a flat partially body 6 (referring to Fig. 1, Fig. 2).

Filament 3 is arranged on the lamp body by the transverse plane, and its gap is very little, and this will be effectively carry out optically focused with the light of emission by the focus of condensing body 2, more utilize the light of emission.Two leg ends are crooked laterally, make curved filament entire length lengthening provided thereon, in less lamp body, improved the length of luminous element, help the luminous quantity of unit volume.The volume of cavity body 7 is little, thereby the overall volume of lamp body is reduced, and raw-material consumption is reduced, and has reduced production cost; The volume of cavity body 7 is little, and its another advantage is, after lamp body was evacuated, remaining oxygen molecule will be seldom, and what this helped tungsten filament is difficult for oxidizedly, has prolonged useful life.
