Abstract
The utility model discloses a shade for an electric bulb. The electric bulb is provided with a lighting member, and the shade is a shell body of predetermined thickness, and is made from transparent material. The shade is provided with an inner wall face and a chamber for containing the lighting member, wherein the inner wall face is at least provided with a light guide part for projecting a large portion of light to the outside of the shade.
Description
Technical field
The utility model relates to illumination component, is meant a kind of lampshade that is used for bulb especially.
Background technology
Since bulb came out, the composition structure of bulb all was to coat tungsten filament with the lampshade that glass is made usually, and when the tungsten filament energising is heated to after incandescent state produces light, light can see through lampshade to external exposure.
Though above-mentioned bulb is applied to various illumination occasions very at large, but can convert light to because of the energy that only is lower than 10%, all the other energy of 90% all change into heat energy, thereby has not good and unusual problem of not environmental protection of efficient, recently the existing light emitting diode that utilizes replaces tungsten filament as light-emitting component, uses the energy consumption problem of improving the aforementioned electric bulb.
But, in the structure of aforementioned various bulbs, be all even surface around the inside and outside wall of lampshade of light-emitting component, will produce reflection or scattering phenomenon when making ray cast that light-emitting component sends, influenced the bulb illuminating effect of environment to external world to the internal face of lampshade.
The utility model content
Main purpose of the present utility model is promptly providing a kind of lampshade that is used for bulb, and inner wall surface thereof has light guide structure, and the light that bulb is sent refracts to the external world fully.
Therefore, take off purpose for before reaching, the utility model discloses the lampshade that is used for bulb, this bulb has an illuminating part, this lampshade is the housing of tool predetermined thickness, and made with light-transmitting materials, and this lampshade has the room and an internal face that can hold this illuminating part, this internal face is furnished with a light guide section at least, throws toward this lampshade outside in order to the most of light with this illuminating part.
In embodiment of the present utility model, this light guide section be one from the internal face of this lampshade the light guiding surface toward outer lug, in order to most of ray guidance that will project from this illuminating part to this lampshade outside.
In embodiment of the present utility model, this light guide section is one to be positioned at the projection of the internal face of this lampshade, and this projection has a light guiding surface at least, in order to most of ray guidance that will project from this illuminating part to this lampshade outside.
Described lampshade, wherein, described light guide section is uniformly distributed in the internal face of this lampshade.
Described lampshade, wherein, this light guide section is one to be the light guiding surface of the internal face of being located at this lampshade circular-arcly, in order to most of ray guidance that will project from this illuminating part to this lampshade outside.
A kind of bulb, it includes:
One pedestal has a conductive part;
One illuminating part is located at this pedestal, and this illuminating part is electrically connected at this conductive part; And
One lampshade, be the housing of tool predetermined thickness, and made with light-transmitting materials, this lampshade has a room and an internal face in order to hold this illuminating part, this internal face is furnished with a light guide section at least, throws toward this lampshade outside in order to the most of light with this illuminating part.
Described bulb, wherein, the light guide section of this lampshade be one from this internal face toward the light guiding surface of outer lug, in order to most of ray guidance that will project from this illuminating part to this lampshade outside.
Described bulb, wherein, the light guide section of this lampshade is one to be positioned at the projection of this internal face, this projection has a light guiding surface at least, in order to most of ray guidance that will project from this illuminating part to this lampshade outside.
Described bulb, wherein, described light guide section is uniformly distributed in the internal face of this lampshade.
Described bulb, wherein, this light guide section is one to be the light guiding surface of the internal face of being located at this lampshade circular-arcly, in order to most of ray guidance that will project from this illuminating part to this lampshade outside.
The beneficial effects of the utility model are, the lampshade that is used for bulb that is provided, because inner wall surface thereof has light guide structure, the light that bulb is sent refracts to the external world fully.
Below now with some embodiment and cooperate and graphic the utility model is described further, wherein:
Description of drawings
Fig. 1 is the cutaway view of the utility model first preferred embodiment; And
Fig. 2 is the cutaway view of the utility model second preferred embodiment.
[main element symbol description]
10 bulbs, 20 pedestals
22 conductive parts, 24 electrical contacts
30 illuminating parts, 32 location divisions
40 lampshades, 41 internal faces
42 light guiding surfaces, 43 light guide sections
50 bulbs, 51 light guiding surfaces
53 internal faces
The specific embodiment
At first see also shown in Figure 1ly, the lampshade 40 that the utility model first preferred embodiment is provided is applied to a bulb 10, and bulb 10 has a pedestal 20 and an illuminating part 30 in addition.
The pedestal 20 of bulb 10 has a periphery and is screw-shaped conductive part 22, makes conductive part 22 can be installed in general family expenses tube face (not shown), and the bottom center of pedestal 20 has an electrical contact 24.
Lampshade 40 is for to make with light-transmitting materials, and the spherical shell of tool predetermined thickness.Lampshade 40 has a room 45, lampshade 40 a plurality of light guide sections 43 that are shaped in internal face 41 one of corresponding room 45 and uniformly dispersing ground.Each light guide section 43 can be the projection that is positioned at internal face 41, makes light guide section 43 have the light guiding surface 42 toward outer lug from internal face 41, and whole internal face 41 presents uniform shape diamond structure by light guide section 43.
Lampshade 40 is located at the top of pedestal 20, and is covered with fully and holding illuminating part 30, and each light guide section 43 correspondence of lampshade 40 internal faces 41 are towards illuminating part 30.As shown in Figure 1, light guide section 43 extends to the place, below of close illuminating part 30 from the position, farthest apart from illuminating part 30 in the distribution of internal face 41.
Via the explanation of above-mentioned composition member of the present utility model, as shown in Figure 1, when illuminating part 30 was luminous because of conducting electricity, light can be projected to each light guiding surface 42, the phenomenon that makes light produce refraction fully by light guiding surface 42 is shone towards lampshade 40 outsides, and the light that penetrates lampshade 40 can produce angular deflection.And throw towards different directions respectively via the light that different light guiding surfaces 42 are reflected, light just can be only merely towards single rectilinear direction irradiation, the light that mutually contiguous light guiding surface 42 is reflected also can reciprocation, thereby increase the emitted ray refractive index of lampshade 40, simultaneously also can condense light, improve and spread the briliancy and the brightness of light.
Please consult shown in Figure 2 again, the bulb 50 that is provided for the utility model second preferred embodiment, it is mainly formed member and generally is same as first preferred embodiment, characteristics are that each light guiding surface 51 is and are located at internal face 53 circular-arcly, when light shines in each light guiding surface 51, can reach the creation purpose that makes the light major part reflect the outside equally.
