Abstract
The utility model discloses a straight tube fluorescent lamp, which comprises a fluorescent tube and a light-transmitting tube sleeved outside the fluorescent tube, wherein a reflective membrane, positioned above the fluorescent tube and curved along the inner wall of the light-transmitting tube, is arranged at the upper part in the light-transmitting tube. The straight tube fluorescent lamp provided by the utility model has the advantage of high light efficiency.
Description
Technical field
The utility model belongs to field of illumination lamp technology, relates in particular to a kind of straight tube fluorescent lamp.
Background technology
In current society, people still are as main lighting with fluorescent lamp.But fluorescent lamp is owing to be mercurous product, and after the fluorescent lamp breakage, mercury directly discharging can cause pollution to environment easily.Afterwards, people had invented the straight tube fluorescent lamp of band outer tube, and it is with a light-transmission tube outside fluorescent tube.Like this, because the airtight of light-transmission tube arranged, even the fluorescent tube breakage can not cause mercury to leak yet.But, because fluorescent lamp is that this light that just causes upwards sending can cause waste to luminous all around.For this reason, the someone can be installed in the straight tube fluorescent lamp of band outer tube in the lampshade, but so, fluorescent tube is distant from the reflecting surface of lampshade, only can reflect limited light, and light efficiency is not very high.
The utility model content
Technical problem to be solved in the utility model provides a kind of straight tube fluorescent lamp that improves light efficiency to greatest extent, to overcome the defective that prior art exists.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of straight tube fluorescent lamp comprises fluorescent tube and is enclosed within the outer light-transmission tube of fluorescent tube, it is characterized in that: described light-transmission tube internal upper part has and is positioned at the fluorescent tube top and along the reflective membrane of light-transmission tube inwall bending.
In the utility model, described light-transmission tube upper inside wall both sides have the fin that extends along the light-transmission tube length direction, and described reflective membrane dual-side is positioned on the described fin.
In order to eliminate the dazzle that produces owing to the overcoat light-transmission tube, and make reverberation more even, described light-transmission tube lower inner wall continuous distribution has the parabola projection.In embodiment of the present utility model, projection can have dual mode, and 1. projection evenly distributes.2. protruding from middle position, outwards fine and close gradually.
Adopt technique scheme, reflective membrane is set directly in the light-transmission tube, reflecting surface is closer apart from the distance of fluorescent tube like this, thereby can as far as possible the light of upwards launching be reflected downwards, thereby can improve light efficiency greatly.In addition, the parabola projection of continuous distribution is set, can eliminates dazzle, and make reverberation more even in the bottom interior wall of light-transmission tube.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Fig. 1 structural representation of the present utility model;
Among the figure:
The 100-fluorescent tube, 200-light-transmission tube, 201-fin, 202-parabola projection, 300-reflective membrane.
Embodiment
As shown in Figure 1, straight tube fluorescent lamp of the present utility model comprises fluorescent tube 100 and the light-transmission tube 200 that is enclosed within fluorescent tube outer 100.
Light-transmission tube 200 upper inside wall both sides have the fin 201 that extends along the light-transmission tube length direction, light-transmission tube 200 internal upper parts have and are positioned at fluorescent tube 100 tops and along the reflective membrane 300 of light-transmission tube 200 inwall bendings, these reflective membrane 300 dual-sides are positioned on the fin 201 of both sides.
In order to eliminate the dazzle that produces owing to overcoat light-transmission tube 200, light-transmission tube 200 lower inner wall continuous distribution have parabola projection 202.
In the utility model, reflective membrane 300 is set directly in the light-transmission tube 200, reflecting surface is just closer apart from the distance of fluorescent tube 100 like this, thereby can as far as possible the light of upwards launching be reflected downwards, thereby can improve light efficiency greatly.In addition, the parabola projection 202 of continuous distribution is set, can eliminates dazzle like this, and make reverberation more even in the bottom interior wall of light-transmission tube 200.
In sum, the utlity model has the high and luminous advantage of uniform of light efficiency.
But, those skilled in the art will recognize that, above-mentioned embodiment is exemplary, be in order better to make those skilled in the art can understand this patent, can not be interpreted as it is the restriction that this patent is comprised scope, so long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
Claims (3)
1. straight tube fluorescent lamp comprises fluorescent tube and is enclosed within the outer light-transmission tube of fluorescent tube, it is characterized in that: described light-transmission tube internal upper part has and is positioned at the fluorescent tube top and along the reflective membrane of light-transmission tube inwall bending.
2. straight tube fluorescent lamp according to claim 1 is characterized in that: described light-transmission tube upper inside wall both sides have the fin that extends along the light-transmission tube length direction, and described reflective membrane dual-side is positioned on the described fin.
