Abstract
The utility model discloses an LED illuminating tube, comprising a tube, lamp holders disposed at two ends of the tube, tube electrode pins arranged in each lamp holder and a strip-shaped LED lamp bar installed in the tube. The strip-shaped LED lamp bar is composed of a PCB board or a MCPCB board and an LED welded on the PCB board or the MCPCB board. The tube, consisting of a reflection layer and a translucent layer, is an integral plastic tube formed by integral injection moulding. Two symmetric notches capable of fixing the strip-shaped LED lamp bar are disposed along the length direction of an inner wall of the tube and comprise two tenons with a cross section of the tube as a plane of symmetry. Compared with a LED illuminating tube of the prior art, the LED illuminating tube of the utility model is not only compact in structure, simple in assembly, easy in manufacturing process and low in cost, but also well overcomes the problem of LED point-like light spots and glare.
Description
Technical field:
The utility model relates to a kind of LED illuminating lamp tube, particularly a kind of with LED as light source and the LED fluorescent tube that is used to throw light on.
Background technology:
Along with people are more and more higher to the requirement of green illumination, LED illuminating lamp tube with plurality of advantages such as low energy consumption, high light efficiency, long service life replaces traditional fluorescent tube gradually, and is widely used in the room lighting in places such as dwelling house, office, railway car; Because the body thermal conductivity factor of existing LED fluorescent tube is lower, do not possess good heat sinking function, the heat that causes LED lamp bar to be produced can't distribute effectively apace and accumulate among body, make the operating temperature in the body too high easily, particularly work as the LED fluorescent tube under the situation of long time continuous working, thereby quicken the aging of LED, influence the service life of LED fluorescent tube; Existing LED illuminating lamp tube complex structure, assembling is inconvenient, and complex manufacturing technology makes shortcomings such as production cost height.
The utility model content:
Technical problem to be solved in the utility model is the defective that overcomes prior art, provides a kind of junction structure compactness, assembling is simple, manufacture craft simple, it is cheap to produce, and the fine LED illuminating lamp tube that has overcome LED point shaped laser spot and glare problem.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED illuminating lamp tube, comprise fluorescent tube, be arranged on the lamp holder of lamp tube ends, each lamp holder is provided with the lamp tube electrode pin, be installed in the bar-shaped LED lamp bar in the fluorescent tube, the bar-shaped LED lamp bar by pcb board or MCPCB plate and be welded on pcb board or the MCPCB plate on LED form, fluorescent tube is made up of reflector layer and photic zone, it is characterized in that: described fluorescent tube is that one is towards molded monoblock type plastic tube, be provided with two fixing draw-in grooves of bar-shaped LED lamp bar symmetrically along tube inner wall length to direction, draw-in groove is that the trip of the plane of symmetry is formed by two with the fluorescent tube cross section.
In above-mentioned LED illuminating lamp tube, the described tube inner wall first half is reflector layer and is provided with reflectorized material; Described fluorescent tube Lower Half inwall is photic zone and irregular striped internal layer is set that the outside is smooth body surface.
Prior art is compared relatively, the utlity model has following advantage:
1, the spare and accessory parts of LED illuminating lamp tube few and can a blow molding, manufacture craft is simple, it is cheap to produce.
2, the LED fluorescent tube directly replaces fluorescent tube to use, and need not to change other parts in the existing fluorescent lamp disc apparatus, and dismounting and installation are all very convenient.
Description of drawings
Fig. 1 is the assembling schematic diagram of the utility model embodiment 1.
Fig. 2 is the decomposing schematic representation of the utility model embodiment 1.
Fig. 3 is the cutaway view of the utility model embodiment 1.
The specific embodiment:
As shown in Figure 1 and Figure 2, the LED illuminating lamp tube of the utility model embodiment, comprise that a fluorescent tube 1, two lamp holders 4, lamp tube electrode pin 5, the bar-shaped LED lamp bar 2 that is installed in the fluorescent tube 1 form, bar-shaped LED lamp bar 2 comprise pcb board or MCPCB plate and be welded on pcb board or the MCPCB plate on LED3 form; Fluorescent tube 1 mainly comprises luminescent layer 101 and hyaline layer 102, and luminescent layer 101 and photic zone 102 are circular arc here, and reflector layer 101 corresponding angles are identical with photic zone 102, and reflector layer 101 is a reflectorized material in addition, and it has good heat-conducting; The irregular striped internal layer of photic zone 102 processing makes it have good semi-transparency, so that the light that LED3 produces can penetrate by the striped internal layer of fluorescent tube 1 inwall; Be provided with two fixing draw-in grooves 6 of bar-shaped LED lamp bar 2 symmetrically along fluorescent tube 1 inwall length to direction, draw-in groove 6 is that the trip of the plane of symmetry is formed by two with fluorescent tube 1 cross section, can bar-shaped LED lamp bar 2 is fixing by this draw-in groove 6; And fluorescent tube 1 two ends also are provided with lamp tube electrode pin 5 respectively by 4 sealings of two lamp holders on each lamp holder 4, and this electrode pin 5 is electrically connected with the bar-shaped LED lamp bar 2 of fluorescent tube 1 inside.
As shown in Figure 3, expression is the cutaway view of fluorescent tube.Be equipped with LED lamp bar 2 in the fluorescent tube 1 inwall draw-in groove 6 among the figure, this LED lamp bar 2 is a rectangle; This LED lamp bar 2 by pcb board or MCPCB plate and be welded on pcb board or the MCPCB plate on LED3 form, can weld a plurality of LED3s on wherein said pcb board or the MCPCB plate here, and these LED3 are and are connected in series, wherein according to the size of LED fluorescent tube 1 and the difference of LED3 power, the quantity of series LED 3 is also inequality.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
