Abstract
The present invention relates to a lamp which utilizes bi-directional light reflection to increase illuminance and an irradiated area, particularly to a bi-directional power-saving reflecting fluorescent lamp in a straight tube shape. By making use of special light alloy extruded section and a reflector which is formed in a way that the inner side of the reflector is provided with a card guiding groove which brings convenience for embedding, attaching and replacing a reflection sheet with a vacuum coating, upward two thirds of a radiation light wave of a light pipe can be effectively reflected to lighting areas. Compared with the prior art, the efficiency of the lamp is enhanced by 3.6 times. Under the same area condition, one lamp of 13W*2 of the lamp can replace three lamps of 40 W in the prior art, and electricity can be saved by 3 to 4 times. The present invention is widely used for indoor illumination.
Description
Technical field
The present invention relates to a kind of bi-directional power-saving straight-tube reflecting fluorescent lamp, be applicable to room lighting.
Technical background
Present fluorescent lighting fixture Fig. 1 and Chinese patent application 89300017.5 Fig. 2 that generally use, its common ground be lampshade vertically downward, the light of fluorescent tube also is irradiation downwards, irradiated area is at 3m
2～4m
2Between, when big or illumination is not enough when daylighting district area light fixture to be installed more, also be the unique way that solves lighting demand, be the ubiquitous problem of present room lighting, also be the update problem of being badly in need of the developmental research novel product.
Summary of the invention
The purpose of this invention is to provide a kind of bi-directional power-saving straight-tube reflecting fluorescent lamp.The radiation light-wave that it can make progress fluorescent tube effectively shines the daylighting district further to both sides.Increase the utilization rate of irradiated area and light fixture light.
The object of the present invention is achieved like this, and bi-directional power-saving straight-tube reflecting fluorescent lamp is by bidirectional reflectance device, end cap and suction top handling attachment mechanism components pie graph 3～5.
The bidirectional reflectance device: adopt the light-alloy extrudate, the inboard is provided with the draw-in groove of leading of being convenient to the attached replacing vacuum coating of embedding reflecting piece, and the sheet base of reflecting piece is the PET synthetic material, thickness 100 μ, and embedding invests leads draw-in groove, is close to reflection R curved surface.The setting of bidirectional reflectance angle is according to environment for use, and the size specification of reflector is drafted, promptly shown in the accompanying drawing 5.Apart from left and right sides reflector center line 5mm～19mm, establishing symmetric points respectively is the center of circle, draw the R curved surface, size range R20mm～R35mm is connected with top inner plane and vertical center line wall, and connects the bidirectional reflectance device that one constitutes by 20 °～40 ° left-right symmetry of angular range that left and right sides reflector center line to vertical center line wall is set.
End cap: with flame-proof ABS synthetic material injection molded, be guard shield reflector two ends fluorescent tube patch lamp socket or ballast, and with inhale top handling attachment mechanism and constitute the decoration and the appearance and modeling of this light fixture.
Inhale top handling attachment mechanism: strengthen the injection mo(u)lding of PP synthetic material with heat-resistant fireproof, described mechanism is by the suspension bracket of laying ballast, be slidingly connected by changeing nail, angular adjustment deck, slide plate and reflector top guide rail.
The present invention and the prior art main performance table of comparisons are as follows:
From the table on as can be seen, compared with the prior art the present invention has following beneficial effect:
1, effectively utilizes the radiation light-wave that makes progress, increased the illuminance in daylighting district.1 13W * 2 surpasses the illumination of 3 40W.
2, because the radiation light-wave that makes progress reflects to both sides by the R curved surface, increased irradiated area, under same illumination requirement and same area environmental condition, prior art must need 3 40W, and the present invention only needs 1 13W * 2 just can surpass the illuminating effect of prior art, can economize on electricity 3～4 times.
3, compared with the prior art Luminaire efficiency and light fixture usage factor have improved 3.6 times.
4, owing to adopted the rare-earth trichromatic energy saving fluorescent tube, colour rendering index reaches more than the 90Ra, obviously improves on color reducibility and visual effect.
