Description

Lampshade

Technical field

The utility model relates to a kind of lampshade of light fixture, particularly relates to a kind of lampshade of good illumination effect.

Background technology

Various light fixtures of Chu Shouing in the market, no matter be fluorescent lamp or incandescent lamp, the making material of its lampshade body generally adopts metal, plastics or textile article, its profile is roughly hemispherical, semielliptical shape or round table-like, it mainly acts on the light that is light source and gathers certain orientation, generally coats white paint or enamel etc. on the inner surface of cover body for this reason.Because the inner surface of cover body is more coarse, its cover body structure is unreasonable in design in addition, so that the quilt cover bulk absorption of part light or the scattering of light source, the light that light source sends is restricted, light can't shine to specific angle according to needs, reflecting effect is relatively poor, thereby makes illuminating effect desirable not to the utmost, the waste electric energy.

The utility model content

The purpose of this utility model is to provide a kind of lampshade of good illumination effect.

For achieving the above object, the utility model provides a kind of lampshade, and it comprises a cover body with non-light transmittance energy, and cover body is made of a plurality of trapezoidal plates and presents the terrace with edge shape that opening end is little, lower open mouth end is big, is coated with metallic reflector on the inner surface of trapezoidal plate.

Described cover body is made of 5～18 trapezoidal plates and is positive terrace with edge shape.

The angle of two of trapezoidal plate opposite side faceted pebbles is 20～72 degree in the described cover body, and the angle of transverse plane is 110～160 degree on trapezoidal plate inner surface and the cover body.

The top that allows lamp socket that bulb is housed be positioned at cover body can be used.

Adopt after the above structure, owing to be coated with comparatively smooth metallic reflector on the trapezoidal plate inner surface, so the reflecting layer quality obtains bigger raising, guarantee only reflection rather than diffusion, be unlikely and lose, so just improved the reflectivity in reflecting layer, make it have very strong reflective function, again because cover body is made of a plurality of trapezoidal plates and to present opening end little, the terrace with edge shape that lower open mouth end is big, its spatial form is improved, so make the light that sends from light source except that direct light, all the other arrive behind the inner surface of trapezoidal plates all through reflective layer reflects, this part light is reflected back again by certain angle and stack mutually, penetrate by lampshade mouth place, make the utilization rate of light source be improved, thereby increased the illumination in the area to be illuminated territory, good illumination effect has also correspondingly been saved electric energy.

Because the metallic reflector on the trapezoidal plate inner surface is comparatively smooth, so when bulb is lighted, all can occur the image of a bulb on the inner surface of each trapezoidal plate, it is the same to light a plurality of bulbs seemingly simultaneously, can present special visual effect, has novelty.

As improvement of the present utility model, the upper bottom surface of described cover body by trapezoidal plate is connected to one and puts in the cover body, constitute by a plurality of trapezoidal plates, be and be inverted positive terrace with edge shape, last opening end is big, lower open mouth end little and have non-light transmittance can lamp holder, the bottom surface of cover body by trapezoidal plate is connected to one and stretches out, constitute by a plurality of trapezoidal plates, be positive terrace with edge shape, last opening end is little, lower open mouth end big and have non-light transmittance can second layer cover body, the quantity of trapezoidal plate in the lamp holder, the quantity of trapezoidal plate is identical with the quantity of trapezoidal plate in the cover body in the second layer cover body, be coated with metallic reflector on the inner surface of trapezoidal plate on the inner surface of trapezoidal plate and in the second layer cover body in the lamp holder, in the cover body in trapezoidal plate and the lamp holder with corresponding trapezoidal plate that this plate joins between angle be 100～150 degree, in the cover body in trapezoidal plate and the second layer cover body with corresponding trapezoidal plate that this plate joins between angle be 120～170 degree.Lamp holder can play the effect of being convenient to settle lamp socket, and second layer cover body can play and enlarge the effect of area to be illuminated territory with further raising light source utilization rate.

In addition, in the described cover body in trapezoidal plate, the lamp holder in trapezoidal plate, the second layer cover body making material of trapezoidal plate be heat-resisting plate glass, scribble pitch-darkly on the outer surface of trapezoidal plate, the metallic reflector that plates on the inner surface is silver layer or aluminium lamination.

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing preferred forms of the present utility model is specifically described:

Referring to Fig. 1, Fig. 2, the utility model provides a kind of lampshade, and it is made up of lamp holder, cover body and second layer cover body with non-light transmittance energy.

Cover body is made of 6 identical trapezoidal plates 1 of area and presents the positive terrace with edge shape that opening end is little, lower open mouth end is big.The angle of two of trapezoidal plate 1 opposite side faceted pebbles 13 is 60 degree in the cover body, and the angle 5 of transverse plane is 151 degree on trapezoidal plate 1 inner surface and the cover body.

The upper bottom surface 11 of described cover body by trapezoidal plate 1 is connected to one and puts in the cover body, constitute by 6 trapezoidal plates 2, be and be inverted positive terrace with edge shape, last opening end is big, lower open mouth end little and have non-light transmittance can lamp holder, the bottom surface 12 of cover body by trapezoidal plate 1 is connected to one and stretches out, constitute by 6 trapezoidal plates 3, be positive terrace with edge shape, last opening end is little, lower open mouth end big and have non-light transmittance can second layer cover body, be the quantity of trapezoidal plate 2 in the lamp holder, the quantity of trapezoidal plate 3 is identical with the quantity of trapezoidal plate 1 in the cover body in the second layer cover body, the angle 6 that the corresponding trapezoidal plate that joins with this trapezoidal plate 1 in trapezoidal plate 1 and the lamp holder in the cover body is 2 is 113 degree, the angle 7 that the corresponding trapezoidal plate that joins with this trapezoidal plate 1 in trapezoidal plate 1 and the second layer cover body in the cover body is 3 is 162 degree, and the lamp socket 4 that is used for installing bulb is pegged graft with the lower open mouth end of lamp holder.
