New description: [New technical field] The present invention relates to a lampshade, and more particularly to a lampshade that can be mounted on a lamp tube and can be clamped to a lamp tube. [Prior Art] The general lighting fixture is mainly composed of three parts: the illumination source, the lampshade and the accessory. Among them, the selection and design of the selected (4) illumination source and lampshade will directly affect the efficiency and quality of the illumination. The material-like lamps are mostly made of a more rigid type of cloth, but are suitable for rooms without fixed guarding areas, or with densely distributed working areas, or places with relatively low requirements for lighting quality, such as offices. Classrooms, etc., therefore, the requirements for the hood are usually lower. The light source installed in the room is mostly a long lamp type and usually does not match the lampshade, or although it is equipped with a lampshade, the (4) used is only simple. The function of blocking and concentrating the light source is not reflective. If it is able to achieve a better brightness distribution and uniform illumination, it is necessary to use a lamp with a power of 咼 to provide better illumination efficiency. Although the general luminaires are not matched with the lampshade or the materials that are easy to use with the non-reflective function type are still expected to provide the photo (4), but the following are missing: ·, in order to achieve the predetermined lighting quality, the number of lamps is usually increased. Dong either uses high-power money, but this practice usually has a large power consumption and a lack of wasted energy. Second, the general lighting is mostly assembled. If you want to change the design, for example, if you install a lampshade or modify the reflector with reflective function to improve the lighting quality, then M336381. Need to replace or disassemble the whole set, which is more troublesome than the modification program. And the inconvenience is shortcoming. • [New Content] Therefore, the purpose of the present invention is to provide a lampshade that can be easily assembled and positioned in a lamp tube to enhance overall lighting quality and efficiency. Thus, the lampshade that can be clamped to the lamp tube is removably positioned in the lamp holder, includes a cover body, and a clamping unit disposed at least two spaced apart from the cover body. The cover body includes a two-arc end surface which is spaced apart from the longitudinal direction of the lamp tube, and an outer cover surface and an inner reflection surface which are connected between the two curved end faces and are spaced apart from each other. The clamping units are disposed on the inner reflective surface of the cover body at intervals along the length direction, and each of the clamping units includes two spaced apart and correspondingly outwardly away from the inner reflective surface. Further bending inwardly and terminating the elastic clamping arm portion of a bottom end edge, and the maximum spacing between the two clamping arm portions is smaller than the diameter of the tube and the bottom of the second clamping arm portion The edge also cooperates with the boundary to define a gap that is smaller than the diameter of the tube. In use, the two elastic central arm portions can be directly opened by the light tube to enlarge the gap, and the light tube can be easily passed through the gap when the light tube is accommodated in the space between the two clamp arms The two clamping arms are reset by their elastic restoring force, because the maximum spacing between the two clamping arms is smaller than the control of the lamp, so that the two clamping arms can be firmly clamped to the lamp a circumferential surface, wherein the lamp cover is clamped to the lamp tube without falling off. At this time, the lamp cover can be rotated relative to the lamp 6 M336381 to a predetermined orientation. When the lamp tube is used for illumination, the light is emitted. Light can be projected through a reflection of the inner reflecting surface of the cover toward a predetermined orientation and achieve an effect of enhancing illumination brightness. The utility model has the beneficial effects that the clamping unit of the lampshade can conveniently clamp the lampshade to the lamp holder without complicated assembly work, and can directly pass through when the lamp tube is activated. The inner reflective surface of the cover enhances the projected illumination light to enhance the illumination brightness and efficiency, and the same illumination requirement can be achieved by using a lower power lamp, so that the novel is relatively easy to wear and can improve illumination. Efficiency, which in turn saves the characteristics and advantages of lighting power. [Embodiment] The above-mentioned and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the drawings. /n
