Abstract
The utility model relates to a highly reflective fluorescent lamp which comprises a lamp housing. The housing is connected with a light tube, a lampshade is also arranged on the housing, and the light tube is arranged in the lampshade; the section of the lampshade is approximately in the shape of M; and the middle part of the M-shaped lampshade is connected to the housing, and two wings thereof extend downwards out of the housing to positions below the center of the light tube arranged in the lampshade. The utility model has the benefits that the lampshade with the approximately M-shaped section is arranged for the light tube and connected to the housing, and the light tube is arranged in the lampshade; and the two wings of the lampshade extend downwards to the positions below the center of the light tube, and are matched with each other to form a reflective radian design of the M-shaped lampshade in a manner that a middle straight line or inwards recessed arc section, a protuberant arc section, a downwards extending arc section and an approximately straight line arc section are tangentially connected, so that light rays emitted from the upper part and the middle-lower part of the light tube are uniformly reflected to the vertically downward direction, thereby increasing the lighting utilization efficiency of the light tube, the uniformity of the light rays and the illumination per unit area, and achieving high practicability and energy conversation of the highly reflective fluorescent lamp.
Description
[technical field]
The utility model relates to a kind of florescent lamp fitting, refers in particular to the high and more uniform florescent lamp fitting of a kind of reflector efficiency.
[background technology]
At present environmental protection notion is subject to people's attention day by day, various environment-friendly and energy-saving lamps also emerge successively, for example in the fluorescent lamp industry, just be converted to T5 formula fluorescent tube more efficient, material-saving by the T8 pipe gradually in recent years, yet in the energy-conservation evolution of fluorescent tube, everybody notices the unit volume luminous efficiency that how further improves fluorescent tube, but ignored the function that light that original florescent lamp fitting sends fluorescent tube lacks focus utilization, promptly existing florescent lamp fitting scarcely is equipped with lampshade, and this has just caused the waste of the luminous scattering of light pipe.Also have seldom the part fluorescent lamp begins to be provided with lampshade for this reason, but this type of lampshade often designs comparatively simple and crude, and structure is very unreasonable, only simply plays an effect of being in the light, there are many shortcomings such as the low and reflection back ray cast of light reflection efficiency is inhomogeneous, can't satisfy application demand.
[summary of the invention]
The purpose of this utility model is to have overcome above-mentioned defective, provides a kind of simple and reasonable, can effectively the light pipe top be reached the high reflecting type florescent lamp fitting of the most of vertical reflection of square on the lower side light to the below.
The purpose of this utility model is achieved in that a kind of high reflecting type florescent lamp fitting, and it comprises lamp casing, and housing is connected with light pipe, and its improvements are: also be provided with lampshade on the housing, the light pipe setting wherein; Described lampshade cross section is approximated to M shape, and the middle part of its M shape lampshade is connected on the housing, and both wings extend downward hull outside;
Be extended down to below the light pipe center that is provided with in the lampshade under the both wings of described M shape lampshade;
Described M shape lampshade is by straightway middle part, and the projection arc section of the tangent connection of both wings, downward arc section and arc section constitute;
Described M shape lampshade is by straightway middle part, and the projection arc section of the tangent connection of both wings, downward arc section and straightway constitute;
Described M shape lampshade is by the arc section middle part of a near linear, and the projection arc section of the tangent connection of both wings, downward arc section and arc section constitute;
Described M shape lampshade is by the arc section middle part of a near linear, and the projection arc section of the tangent connection of both wings, downward arc section and straightway constitute;
Described straightway (or arc section of near linear) becomes 40～55 degree with horizontal line;
The radian of described downward arc section is ￠ 45～￠ 60mm;
The radian of described projection arc section is ￠ 10～￠ 20mm.
Than common florescent lamp fitting, the beneficial effects of the utility model are to be provided with the lampshade that a cross section becomes approximate M shape for light pipe, this lampshade is provided with light pipe in being connected on the housing wherein, be extended down under its both wings below the light pipe center, the middle part straight line or the indent arc section that cooperate the tangent connection that constitutes M shape lampshade, the projection arc section, downward reflective radian design of changing radian and near linear arc section, thereby effectively with the fluorescent tube top and on the lower side the light that distributed of side evenly reflex to vertically downward direction, thereby strengthened the luminous service efficiency of light pipe, improved the light uniformity and unit are illumination, very practical energy-conservation.
[description of drawings]
Below in conjunction with accompanying drawing in detail concrete structure of the present utility model is described in detail
Fig. 1 is a partial structurtes schematic perspective view of the present utility model.
Fig. 2 is a sectional view of the present utility model.
[specific embodiment]
As shown in Figure 1, the utility model relates to 1, a kind of high reflecting type florescent lamp fitting, it comprises that the T8 fluorescent tube changes the lamp casing 1 of T5 fluorescent tube, both sides, housing 1 upper end are T8 fluorescent tube socket 101, the lower end is connected with lampshade 2 and is provided with T5 fluorescent tube socket 102 in both sides, and light pipe 3 inserts on the T5 fluorescent tube socket 102 as in the lampshade 2.
Referring to Fig. 2, lampshade 2 cross sections are approximated to M shape, this M shape lampshade 2 is by the arc section of indent middle part 201 (or directly adopt straightway middle part also can), the projection arc section 202 of the tangent connection of both wings, downward arc section 203 and near linear arc section 204 (or directly adopting straightway) constitute, and are extended down under the both wings of lampshade 2 below light pipe 3 centers that are provided with in the lampshade.The middle part 201 of M shape lampshade 2 is connected on the housing 1, projection arc section 202, downward arc section 203 and the 204 tangent connections of near linear arc section, have separately radian to adapt to reflection with light pipe 2 light, wherein the radian of projection arc section 202 is got ￠ 10～￠ 20mm usually, the radian of corresponding downward arc section is got ￠ 45～￠ 60mm, and be extended down to the following z place, light pipe 3 centers that is provided with in the lampshade under the near linear arc section bottom, and become at w=40～55 degree angles in horizontal line, thereby realize effectively fluorescent tube 3 tops to be reached the purpose that the square on the lower side light that is distributed all reflexes to direction vertically downward, not only strengthened the luminous service efficiency of light pipe, the light uniformity and unit are illumination have also been improved, and lampshade 2 is rational in infrastructure, be fit to aluminium section bar machine-shaping, light province material, whole florescent lamp fitting is particularly suitable for the T8 fluorescent tube changes T5 lampshade formula electricity-saving lamp, the outward appearance light is attractive in appearance, be equipped with high power electronic ballast, can further increase the energy-efficient effect of integral fluorescence lamp light fixture, very practical energy-conservation.
