The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Embodiment 1:

As shown in Figure 1, the rotary built-in power fluorescent lamp of LED provided by the invention, comprise fluorescent tube 1, power supply module 5, lamp plate assembly 4, two go up tube head 3 and two following tube heads 2; All be arranged with lamp base 9 on each on the tube head 3; Power supply module 5 is positioned at fluorescent tube 1 with lamp plate assembly 4, and power supply module 5 is positioned at the upper end of lamp plate assembly 4, and two following tube heads 2 are socketed on fluorescent tube 1 two respectively; Each goes up tube head 3 in all nested one of tube head 2 outsides down; Like Fig. 2, shown in Figure 3, row's pin 6 of realizing that power supply module 5 and lamp plate assembly 4 are electrically connected is installed between power supply module 5 and lamp plate assembly 4, row's pin 6 is provided with the stitch 61 of the corresponding conducting in four groups of both sides; Be equipped with four jointing holes 45 of welding mutually on power supply module 5 and the lamp plate assembly 4 with stitch 61; Jointing holes 45 on power supply module 5 and the lamp plate assembly 4 all with corresponding electrical interconnection conducting, like Fig. 4, shown in Figure 6, tube head 3 openends are equipped with two positioning boss 32 and two positive stop lug boss 31 on two; Two positioning boss 32 and two positive stop lug boss 31 are and are symmetrical set; And distribute along last tube head 3 openend right-angled intersections, to be equipped with 21, six positioning of six positioning blocks 22 and two positive stops blocks 22 be that tube head inwall 45 is spent annular spread under the edge with two positive stops 21 in the junction of tube head 2 inwalls and dividing plate 24 down for each; And six positioning blocks 22 are for be symmetrical set in twos; Two positive stops 21 are for being symmetrical set, and positioning block 22 cooperates with positive stop lug boss 31 with the positioning boss 32 of last tube head 3 openends respectively with positive stop 21, and the concrete number of certain above-mentioned positioning boss 32, positive stop lug boss 31, transpose block 22 and positive stop 21 can be confirmed according to the requirement of real illumination different angles; Just differ one for example at this, also be provided with routing hole 25 on the dividing plate 24.

As shown in Figure 5; On positive stop lug boss 31, be provided with position-limit foot 311; Positive stop 21 is L-shaped, and its lateral part and longitudinal component intersection are to the spacing of the tube head 2 inwalls down thickness greater than positioning boss 32, less than the extension elongation of the position-limit foot that stretches out on the positive stop lug boss 31 311; The height of positive stop 21 is higher than the height of the block 22 of transposing, and last tube head 3 is broken away from positioning block 22 by drawing drawing distance is greater than the height of positioning block 22 and be lower than the height of positive stop 21.

The internal links mode of last tube head 3 and following tube head 2 is described below: it is fixing through the tightening member 7 of scurrying reposition element 8 with following tube head 2 to go up tube head 3; Tightening member can be screw, bolt etc.; Reposition element can be spring, elastic washer etc.; Last tube head 3 is built-in with step installing hole 33; The dividing plate 24 of following tube head 2 is provided with the fixing hole 23 with step installing hole 33 same axis, and the tightening member 7 of scurrying reposition element 8 runs through step installing hole 33 and cooperates with fixing hole 23, and reposition element 8 is positioned at step installing hole 33.Above-mentioned this connected mode good stability.

Power supply module 5 directly is fixedly connected through row's pin 6 with lamp plate assembly 4 in the said structure, makes to be connected firmly that power supply can not rock in the use; And row's pin 6 connects good electric property, and the electric wire in the middle of having substituted connects, and has avoided line ball; Break risk, reduced high temperature, high pressure putting in order the influence of lamp; Simultaneously each down tube head 2 inwalls cooperate the replacement purposes of 0 °, 45 °, 90 ° of realization lighting angles and-45 ° with two positioning boss 32 and two positive stop lug boss 31 that two positive stops 21 and last tube head 3 openends are provided with six positioning blocks 22 that the junction of dividing plate 24 is provided with.

In practical implementation, when power supply module 5 was installed through row's pin 6 with lamp plate assembly 4, stitch 61 upper ends of four groups of corresponding conductings in both sides were inserted in four jointing holes 45 of power supply module 5 on row's pin 6, and weld; Stitch 61 lower ends of four groups of corresponding conductings in both sides are inserted in four jointing holes 45 of lamp plate assembly 4 on row's pin 6, weld equally.Like Fig. 7, shown in Figure 8, in use carry out fluorescent tube 1 rotation adjusting, the user only needs that tube head 3 is rotated in the pull-up; Be connected owing to match with positive stop 21 through transpose boss 32 and positive stop lug boss 31 and the block 22 of transposing between last tube head 3 and the following tube head 2; And the step installing hole 33 of last tube head 3 is built-in with reposition element 8, thus in pulling during tube head 3, the tension force effect of reposition element 8 and under the double condition in tube head 3 and the slit of following tube head 2 junctions; Last tube head 3 will outwards move a segment distance; Rotate next one positioning block 22 places this moment again by hand, aim at the positioning block 22 on the positioning boss 32 gone up on the tube head 3 and the following tube head 2 then, loose one's grip after hearing " click " one; Last tube head 3 is on the snapping with following tube head 2; And reposition element 8 is also just got back to initial position, because reposition element 8 has pretightning force, therefore goes up tube head 3 and can not become flexible with following tube head 2.
