Description

A kind of lampshade and fluorescent tube

Technical field

The utility model relates to lighting field, relates in particular to a kind of lampshade and fluorescent tube.

Background technology

Present with light emitting diode (Light Emitting Diode, LED) decorative lighting, commercial lighting and office lighting field have been widely used in for the fluorescent tube of light source, the structure of this class fluorescent tube as shown in Figure 1, housing 11 as lampshade has the strip groove 111 that is parallel to lampshade 11 housing short transverses usually, and the inside of fluorescent tube is provided with led light source 12.The main effect of this housing 11 is the luminous secondary light-distributions that carry out to LED, thereby reduces dazzle, and the effect of dust and moisture is also arranged simultaneously.Because the built-in led light source of this class fluorescent tube generally all is a spot light, can not effectively improve the effect of spot light as the housing 11 of lampshade, then need to obtain uniform line source effect in actual the use, present solution is to adopt the vaporific housing 11 of milky, can obtain uniform line source effect, but the vaporific housing 11 of this milky also brings bigger light losing simultaneously, has reduced the brightness of illumination.

The utility model content

Technical problem in view of prior art exists the utility model proposes a kind of lampshade and fluorescent tube, and this lampshade can neither increase light losing, can improve the spot light effect again simultaneously.

In order to solve the problems of the technologies described above, the utility model proposes a kind of lampshade, comprise the first transparent housing, wherein,

Offer a plurality of parallel transverse concave grooves on described first housing.

Correspondingly, the utility model embodiment also proposes a kind of fluorescent tube, comprises above-mentioned lampshade and the light source that is arranged at described lampshade inside.

Implement the utility model embodiment, by offering a plurality of parallel transverse concave grooves on described first housing, this annular recess can converge the light of light source, when many annular recess are side-by-side, can effectively spot light be improved as line source, because the housing of lampshade still keeps pellucidity, with respect to the vaporific lampshade of milky, can reduce light losing, so the lampshade of the utility model embodiment light losing can be neither increased, the spot light effect can be improved again simultaneously.
