Compared with prior art, the beneficial effect of the utility model is:
(1) improved the fixing problem that can not regulate of LED fluorescent tube and conventional fluorescent pipe light projector direction; The light projector angle of the said fluorescent tube of the utility model can be regulated arbitrarily in adjustable extent; To reach best daylighting state, overcome the light efficiency waste, make full use of light source; Mounting means is consistent with traditional fluorescent tube simultaneously, need not change support and increase other part, changes convenient and swift;
(2) said housing adopts the PC cover to be connected with the aluminium section bar buckle; Utilization plastic cement characteristic and aluminium section bar organically combine; Buckle structure is reasonable, can alleviate the internal stress that the deformation of PC cover own produces, and recovers the stress of strain; Avoid the PC cover to be in for a long time under the great internal stress effect of stress, thereby prolong the life-span of PC cover;
(3) driving power adopts the tubular type suit, avoids the use of the fish paper binding, reduces volume, simplifies assembling procedure, enhances productivity, and practices thrift cost.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done detailed explanation.
The utility model is based on a kind of package assembly of LED fluorescent tube; Like accompanying drawing 1-2, this fluorescent tube comprises lamp body and is installed in the lamp socket 6 at lamp body two ends, lampholder cover assembly that the lampholder cover assembly is installed in the lamp socket outside; Pcb board is set in the lamp body; LED lamp pearl is installed on the pcb board, and lamp body can rotate with respect to lamp socket with the lampholder cover assembly, thereby realizes the adjustment of the light projector angle of lamp.
Like Fig. 6-10,Said lampholder cover assembly comprises lampholder cover 2 and rotatable lamella 5 and centring ring 4, and rotatable lamella 5 is installed in the lampholder cover and is fixed on the lampholder cover 2 through screw; Centring ring 4 reinstalls lampholder cover 2, and centring ring 4 lower ends are provided with bayonet socket 41, and lampholder cover 2 correspondences are provided with screens 21, and the corresponding connection with screens of this bayonet socket is fixed centring ring and lampholder cover; Centring ring 4 upper ends are that salient point is established at annular flake and annular flake edge, annular flake position, back is installed is exposed to lampholder cover 2, pack in the lamp socket 6 in this extending part, and this salient point is corresponding with the groove of lamp socket 6 inner peripherys; When lamp body rotated relative to the lampholder cover assembly, the annular flake position of centring ring 4 produced elastic deformation, and salient point is around the groove rotation of lamp socket 6; The salient point revolution is gone into the then light projector change in location certain angle of lamp body of a groove; Then can send the sound of " ticking ", when lamp body is realized rotating relative to the lampholder cover assembly, can hear the sound of " ticking "; Make the operator that tangible feel and sense of hearing arranged, be convenient to accurate adjusting angle.In the present embodiment, on the rotatable lamella 5 of lampholder cover assembly, establish a limited post, establish stopper slot on the lamp body 2, being used of limited post and stopper slot defines the lampholder cover assembly anglec of rotation and be 180 degree, and be shown in figure 11.
The lamp body 2 of the LED fluorescent tube that light projector angle described in the present embodiment is adjustable covers 8 buckles by aluminium section bar 9 with PC to be formed, and establishes pcb board in it, and pcb board 10 is pressed between aluminium section bar 9 and the PC cover 8 fixing; Pcb board 10 can not be moved up and down, and lamp body 2 left and right directions have lamp socket 6 fixing, like accompanying drawing 3; On the PC cover, be provided with button bit and presser feet, button bit is used for being interlockingly connected with aluminium section bar, and presser feet is used for the crimping pcb board; Button bit and presser feet form a pair of active force and reaction force; Act on the PC cover 8, make its fastening on aluminium section bar 9, relative fixed." people " font design of button bit and presser feet, utilization mechanics decomposition principle is in conjunction with PC plastic cement strain principle; PC cover and aluminium section bar power that links closely each other and the power that compresses pcb board are comprehensively decomposed, the PC cover is linked closely with aluminium section bar, can pcb board be fixed on the aluminium section bar on the other hand; Alleviate the internal stress that the deformation of PC cover own produces; Recover the stress of strain, avoid the PC cover to be in for a long time under the great internal stress effect of stress, thereby prolong the life-span of PC cover.
When lamp body and lampholder cover assembly and lamp socket assembling, earlier lamp socket 6 usefulness screws 7 are fixed on the aluminium section bar 9, lamp body and lamp socket 6 are fused; As shown in Figure 5; Screw 7 adopts from the merit screw, avoids machining screw on aluminium section bar 9, directly can fixed lamp-socket 6 on aluminium section bar 9 with 7 dozens on screw.
In the present embodiment, power supply assembling is as shown in Figure 4, and power supply module is hidden in the power supply sleeve pipe 14 fully, and termination lid 13 is blocked two ends, form one close-shaped; Termination lid 13 is reserved four apertures, and four apertures also have the effect of vented exhaust except that confessing line and lambda line; The heat conduction that accelerating power source self produces; Promote radiating efficiency, the heat that lets power supply produce conducts fast, reduces power supply and causes the power supply decay aging owing to temperature is too high.Power supply module has a style of one's own, and is easy to assembly, flexibly, avoids the end of a thread frequent bending solder joint when assembling can effectively be enhanced productivity by the phenomenon that fractures, and avoids the generation of defective products.Driving power adopts the tubular type suit, and does not use the fish paper binding, the hidden danger of distortion and dislocation when having solved electronic devices and components and fish paper, heat-shrink tube binding.
The foregoing description is merely the preferred implementation of the utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the utility model design, any conspicuous replacement all should fall within the protection domain of the utility model.
