Abstract
The utility model discloses an improved LED (Light-Emitting Diode) fluorescent lamp tube, which comprises a lamp tube body, a lampshade, a substrate, LED lamp beads and reflecting bars, wherein the lampshade covers on the lamp tube body; the substrate is arranged in the lamp tube body; the LED lamp beads are fixed on the substrate; the reflecting bars are provided with arc-shaped reflecting surfaces; two reflecting bars are symmetrically arranged on both sides of the substrate; and the arc-shaped reflecting surfaces are convex cambered surfaces projecting towards the sides of the LED lamp beads. The arc-shaped reflecting surfaces are the convex cambered surfaces projecting towards the side ends of the LED lamp beads, so that the uniformity of brightness distribution on the lampshade can be improved to the maximum extent; and light rays can be prevented from being reflected repeatedly on the reflecting bars through the convex cambered surfaces of the reflecting bars, so that the absorption of light on the reflecting surfaces is reduced, the overall brightness of a lamp is improved, and the using quantity of the LED lamp beads can be reduced.
Description
Technical field
The utility model relates to lighting technical field, particularly a kind of improved LED fluorescent tube.
Background technology
The LED fluorescent tube generally adopts the low-power LED lamp pearl as light source, for reaching the illuminating effect identical with the traditional fluorescent lamp pipe, needs to use a large amount of low-power LED lamp pearls, but just causes the waste of material and processing cost to remain high.Afterwards, along with the development of LED technology, the improving constantly of LED light efficiency, the luminous flux of single LEDs increases, a spot of LED lamp pearl before the LED fluorescent tube can use is used the identical luminous flux of fluorescent tube of a large amount of low-power LED lamp pearls before just reaching on the whole.LED fluorescent tube afterwards uses a small amount of LED lamp pearl, though can reduce material and cut down finished cost, but because the minimizing of LED lamp pearl quantity, distance in the fluorescent tube between the LED lamp pearl increases and the dark space occurs, and the luminous flux of single LEDs makes that than increasing in the past the Luminance Distribution on the LED fluorescent lamp shade is more inhomogeneous, and whole lampshade seems in the place near LED lamp pearl can be very bright, and the place in the middle of two LED lamp pearls is very dark, and lampshade integral body seems light and dark.This not only makes ornamental, the comfortableness of fluorescent tube reduce, and can increase dazzle, makes lighting quality descend.In order to increase the uniformity of Luminance Distribution on the LED fluorescent lamp shade, generally can increase the reflection limit on the both sides of LED and redistribute the light distribution.The general method that adopts generally has two kinds at present, and a kind of is to increase straight flange type reflector, but straight flange type reflector control luminous energy power is limited, and is limited to the raising of lampshade luminance uniformity.Another is to increase the inner concave shape reflector, though the effect of inner concave shape reflector increase lampshade luminance uniformity is better slightly than straight flange type effect, can causes part to diffuse and repeatedly reflecting in reflector, makes whole Luminaire efficiency reduce.
The utility model content
The purpose of this utility model is to solve the existing in prior technology problem, inhomogeneous at Luminance Distribution on the present LED fluorescent tube lampshade, the problem that light and dark striped occurs, provide a kind of simple in structure, illuminance distribution on whole lamp brightness height and the lampshade, the good LED fluorescent tube of control light effect.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
LED fluorescent tube of the present utility model, comprise lamp tube body, cover at lampshade on the lamp tube body, be located at the substrate in the lamp tube body, be fixed on the LED lamp pearl on the substrate, and, reflection bar with curved reflecting surface, described reflection bar are two and are symmetricly set in the substrate both sides that this curved reflecting surface is the convex globoidal to LED lamp pearl side projection.
Described curved reflecting surface has at least a curvature.
Described lamp tube body is made of aluminium section bar.
Described reflection bar and lamp tube body are one-body molded.
Described lamp tube body left and right sides end is respectively equipped with end cap.
Compared with prior art, the beneficial effects of the utility model are:
LED fluorescent tube of the present utility model, the reflection bar that has curved reflecting surface in the setting of substrate bilateral symmetry, because curved reflecting surface is the convex globoidal with respect to LED lamp pearl side projection, therefore, after increasing reflection bar, can control light more neatly, redistribute the light to the lower part of brightness on the lampshade, can farthest improve the uniformity of Luminance Distribution on the lampshade; And the cambered surface of this reflection bar projection can be avoided light repeatedly reflection on reflection bar, reduces reflecting surface to the absorption of light, improves the brightness of light fixture integral body, thereby can reduce the use amount of LED lamp pearl.

The specific embodiment
Below in conjunction with accompanying drawing structure of the present utility model is made further explanation and description, but be not to be restriction to the utility model structure.
As shown in Figure 1, LED fluorescent tube of the present utility model comprises lamp tube body 2, cover at lampshade 1 on the lamp tube body, be located at the substrate 4 in the lamp tube body 2, be fixed on the LED lamp pearl 3 on the substrate 4, have the reflection bar 21 of curved reflecting surface, and two left and right sides end caps 5 of lamp tube body.
Shown in Fig. 2～4, reflection bar 21 is two and is symmetricly set in substrate 4 left and right sides that the curved reflecting surface 22 of reflection bar 21 is the convex globoidal to LED lamp pearl side projection, as Fig. 3.This curved reflecting surface has at least a curvature, and in this enforcement, curved reflecting surface tool 22 has a kind of curvature, that is, the cross section of this curved reflecting surface 22 is for any segmental arc on the circle, as Fig. 4.
As Fig. 5, lamp tube body 2 is to be made of aluminium section bar, and reflection bar 21 is one-body molded with lamp tube body, so that processing and manufacturing.
Accompanying drawing 6 shows the trend of light after wherein the curved reflecting surface 22 of a reflection bar reflects that LED lamp pearl 3 sends.By shown in the figure as can be seen, can reflex to any part on the PC lampshade 1 through curved reflecting surface 22 light reflected.Therefore, overcome the defective that straight flange type reflector can only reflex to light the lampshade finite part.Curved reflecting surface 22 catoptrical angular ranges are bigger.Thereby the easiest light and shade striped that occurs is caused lighting tube brightness lampshade bottom pockety, and curved reflecting surface 22 can be invested more rays herein, and therefore, fluorescent tube brightness of the present utility model is very even, does not have light and dark striped.From accompanying drawing 6 as can be seen, light is gone out from the curved reflecting surface whole direct projections in 22 reflection backs, can not cause reflecting surface to the absorption again of luminous energy because of secondary reflection, so, the utility model can improve the brightness of whole light fixture, thereby the LED lamp pearl that can use less amount, reach and reduce the material use amount, lower the effect of manufacturing cost.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or distortion are not broken away from spirit and scope of the present utility model, if these changes and distortion belong within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and distortion.
