The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Fig. 1～Fig. 6, the concentric fluorescent lamp of a kind of adjustable light direction that the utility model embodiment provides, comprise that an outer tube 1 and is located at the fluorescent tube 2 in outer tube 1, outer tube 1 and fluorescent tube 2 arrange with one heart, the hollow tube that outer tube 1 is both ends open, the both ends open of outer tube 1 is fixedly connected with a joint 3 respectively, and joint 3 is with one enclosing cover 4 is detachable coordinates;
Described outer tube 1 is transparent or semitransparent glass tube, outer tube 1 can be also transparent or semitransparent plastic tube, in outer tube 1, be installed with a reflection shield (not shown), the cross section of reflection shield is arc, reflection shield is made by aluminium foil, nickel foil or nanometer reflectorized material etc., and reflection shield outwards reflects away for the light that fluorescent tube 2 is sent, to improve the utilization ratio of light, also avoided next reflective at reflection shield of outer tube 1 outer setting simultaneously, saved production cost;
2 liang of tops of described fluorescent tube are respectively equipped with two bronze medal pins 21, two bronze medal pins 21 connect for the both positive and negative polarity of power supply, the energising illumination of realization to fluorescent tube 2, the sidewall on 2 liang of tops of fluorescent tube is respectively equipped with a spline plane 22, the linear composition that the cross section of fluorescent tube 2 at spline plane 22 places is oppositely arranged by two arcs that are oppositely arranged and two;
Described joint 3 comprises one first link 31 and one second link 32, the first link 31 is tightly connected with the opening of outer tube 1, the second link 32 peripheries are provided with some evenly distributed draw-in groove 321(or convex tendons), on joint 3, being also provided with one arranges vertically and can hold the installing hole 33 that fluorescent tube 2 penetrates, installing hole 33 and fluorescent tube 2 interference fit or matched in clearance;
Described enclosing cover 4 inwalls are provided with some evenly distributed convex tendon 41(or draw-in grooves), the convex tendon 41 of enclosing cover 4 coordinates with the draw-in groove 321 of the second link 32, thereby enclosing cover 4 and joint 3 are fixed together, when needs are pulled down enclosing cover 4, directly enclosing cover 4 are outwards extracted; Particularly, the convex tendon 41 of enclosing cover 4 is conical protrusions, the draw-in groove 321 of the second link 32 is cone-shaped groove, adopt conical convex tendon 41 and draw-in groove 321, both the convex tendon 41 of being convenient to enclosing cover 4 inserts in the draw-in groove 321 of the second link 32, make enclosing cover 4 and the second link 32 fixations, the convex tendon 41 of being convenient to again enclosing cover 4 is easily extracted from the draw-in groove 321 of the second link 32 is interior, thereby has improved the dismounting efficiency of enclosing cover 4; Or the draw-in groove of enclosing cover 4 coordinates with the convex tendon of the second link 32, the draw-in groove of enclosing cover 4 is cone-shaped groove, and the convex tendon of the second link 32 is conical protrusions, equally also can realize the object of the dismounting efficiency that improves enclosing cover 4; The end of enclosing cover 4 is provided with a fixing hole 42, fixing hole 42 comprises two curved portions that are oppositely arranged 421 and two linear portion that are oppositely arranged 422, curved portions 421 coordinates with the outer wall of fluorescent tube 2, linear portion 422 coordinates with the spline plane 22 of fluorescent tube 2, after enclosing cover 4 is fixed on the second link 32 of joint 3, fixing hole 42 on enclosing cover 4 can be tightly fixing by fluorescent tube 2, and fluorescent tube 2 cannot be rotated relative to enclosing cover 4.
The operation principle of fluorescent lamp of the present utility model is: in the time need to adjusting the light direction of fluorescent lamp, first fluorescent lamp is removed from mounting bracket (not shown), then enclosing cover 4 is pulled up from the second link 32 of joint 3, then by outer tube 1 with joint 3 after enclosing cover 4 rotates certain angle, again enclosing cover 4 is fixed on the second link 32 of joint 3, finally fluorescent lamp is fixed on mounting bracket, because having produced, outer tube 1 relatively rotates, therefore the reflection shield in outer tube 1 also produces relative rotation thereupon, the light reflection that reflection shield sends fluorescent tube 2 is to other directions, thereby realized the adjusting to fluorescent lamp light direction.If the light direction of fluorescent lamp does not reach required direction, can continue according to the method described above to regulate, until reach required light direction.
In sum, the fluorescent lamp that the utility model provides, can be by regulating the rotational angle of outer tube 1 enclosing cover 4 relative to joint 3, regulate the light direction of fluorescent lamp, thereby expanded the illumination zone of fluorescent lamp, avoid several fluorescent lamps of many installations to expand illumination zone, saved electric energy, reduced use cost.
In addition, by setting draw-in groove 321(or the convex tendon on the second link 32) and enclosing cover 4 on convex tendon 41(or draw-in groove) quantity, can set the degree of regulation of fluorescent lamp light direction.For example, four draw-in grooves 321 can be set on the second link 32, four convex tendons 41 are set simultaneously on enclosing cover 4, so, the degree of regulation of fluorescent lamp light direction is 90 °, and outer tube 1 is with joint 3 relative to the every lattice that rotate of enclosing cover 4, and the light direction of fluorescent lamp changes 90 °.In practice, can, according to different use occasions, set in the manner described above the degree of regulation of fluorescent lamp light direction.
The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
