Lampshade structure

Technical field

The relevant a kind of lampshade of the utility model aims to provide a kind of light emitting diode bulb that is applicable to especially, to increase the lampshade structure of light emitting diode bulb range of exposures.

Background technology

More ferment and national governments will forbid under the policy of incandescent lamp bulb future successively in the energy-conservation subject under discussion in whole world day, present optimal mode promptly is to utilize light emitting diode (LED) as light emitting source, light emitting diode (LED) is held its high efficiency under the arm, advantage energy-conservation and adjustable optical activity forms agitation gradually in illumination market, and it has been the focus of attracting attention in the whole world in application such as street lamp, car light, outdoor lighting, situation illuminations.

Have at present and utilize the light emitting diode bulb of light emitting diode (LED), adopt the power supply kenel of general incandescent lamp bulb, can directly be installed on the conventional bulb seat and use as light emitting source; Only, when the similar light emitting diode bulb of commonly using is lighted, LED source as light emitting source belongs to direct light, the light source that whole light emitting diode bulb produced can only towards light emitting diode over against area illumination, and fail the outer peripheral areas of light emitting diode avris is produced illuminating effect.

Moreover, commonly use the employed lampshade of light emitting diode bulb and be as shown in Figure 1 circular-arc more, it commonly uses lampshade 10 does not only have appropriate design and planning for the light source irradiating angle or the light projector scope of light emitting diode 20, even if the quantity of the power of raising light emitting diode 10 or increase light emitting diode still can't solve the problem of LED light source device irradiating angle deficiency; Especially, the bright spot that is produced from lampshade 10 outside direct-view light emitting diodes 20 thereby make us not feeling well easily.

The utility model content

The technical problem that the utility model solved is promptly providing a kind of lampshade structure that is applicable to light emitting diode bulb especially, to increase the light projector scope of light emitting diode bulb.

The technical solution of the utility model is: a kind of lampshade structure, be provided with an opening for and the light source set of bond, and include: one first refraction part, be located at this lampshade relatively near the inboard section around the light source group, constituted by the corner angle of some protrusions; One first surface is located at this lampshade relatively near the outside section around the light source group, for being the curved surface that concaves one day.

Wherein, this lampshade is one to be half elliptic shell-like structure body.Other has one second curved surface to be connected between this first surface and this lampshade top, and second curved surface is to be a curved surface that protrudes toward the outer side, and its thickness also successively decreases towards this lampshade top-direction.This lampshade inside top is provided with one second refraction part, and this second refraction part is made of the protruding grain of some protrusions.This lampshade is the Merlon lampshade.This lampshade is the acryl resin lampshade.This lampshade is the polyvinyl chloride lampshade.

The beneficial effects of the utility model are:

1, lampshade of the present utility model is for be half elliptic shell-like structure body without exception, its except have an opening for the light source set of bond, be provided with first refraction part of some corner angle in addition near the inboard section around the light source group at it, be provided with the first surface that concaves one day at it near the outside section around the light source group, and be provided with second curved surface that the relative orientation outside protrudes and be connected in first surface and extend between the lampshade top, the thickness-tapered of its second curved surface also successively decreases towards the lampshade top-direction.When using, can reflect towards first surface by the light of first reflecting part light source group periphery, and intersect at a point after under the effect of first surface, making light ejaculation lampshade, and then allow part light directly towards the irradiation of the outside of lampshade, and allow light partly via the reflex of first surface outer sidescattering towards lampshade, promote the light source irradiating angle and increase the light projector scope.

2, under the effect of second curved surface, can avoid looking at the bright spot that the light source group is produced straight by the lampshade outside.

3, be provided with some protruding second granular refraction part at lampshade inside top section,, make the integrated light source group produce uniform brightness expression effect, and can prevent dazzle by the diffusion effect and the atomizing face of causing that second refraction part is produced.

The specific embodiment

Lampshade of the present utility model is used the light range of exposures that increases light emitting diode bulb mainly as the optics mechanism of light emitting diode bulb; As shown in Figure 2, this lampshade 30 can be made by Merlon (PC), acryl resin or polyvinyl chloride materials such as (PVC), and it is except being provided with an opening 31 confessions and the light source group 40 of light emitting diode bulb engages; Other includes following structure: one first refraction part 32, be located at this lampshade 30 relatively near the inboard section around the light source group 40, and constituted by the corner angle 311 of some protrusions.

One first surface 33 is located at this lampshade 30 relatively near the outside section around the light source group 40, for being the curved surface that concaves one day.

One second curved surface 34 is connected between this first surface 33 and this lampshade 30 tops, and for being a curved surface that protrudes toward the outer side, its thickness also successively decreases towards these lampshade 30 top-direction.In the specific implementation, lampshade 30 of the present utility model is good generally to be half elliptic shell-like structure body, and is provided with one second refraction part 35 in its inside top, and this second refraction part 35 is made of 351 of the protruding grains of some protrusions.

As shown in Figures 2 and 3, under lampshade 30 effects of the present utility model, the light of these light source group 40 avris can be via this first reflecting part 32 towards these first surface 33 refractions, and intersect at a point after under the effect of this first surface 33, making light ejaculation lampshade 30, and then allow part light directly towards the irradiation of the outside of lampshade 30, and allow light partly then via the reflex of first surface 33 outer sidescattering towards lampshade, the light source that light source group 40 is produced is contained 300 ° range of exposures (as shown in Figure 4), and reaches the purpose that promotes the light source irradiating angle and increase the light projector scope.

And the bright spot that under the effect of this second curved surface 34, can avoid the light emitting diodes 41 by the outside direct-view of lampshade 30 light source groups 40 to be produced, avoid causing the discomfort of use; Especially, as shown in Figure 5, under the refraction action of this second refraction part 35, can make the light that passes through form the diffusion and the atomizing face of causing, make the integrated light source group produce uniform brightness expression effect, and can prevent dazzle.
