Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As depicted in figs. 1 and 2, this application discloses a kind of adjustable LED pendent lamps, mainly by 4, two side plates 3 of crossbeam,
One lampshade 1, the second lampshade 2 and LED lamp bead 61 form, wherein 61 emitting linear light beam of LED lamp bead, and two side plates 3 are solid respectively
The both ends of crossbeam 4 are scheduled on, the both ends of two lampshades are fitted on corresponding side plate 3, and the second lampshade 2 can be in two side plates 3
Between move up and down, in actually manufacture, the second lampshade 2 mobile back side panel 3 on the first lampshade 2 can cover both ends, therefore
The end that the area of side plate 3 is greater than the first lampshade 1 and the second lampshade 2 encloses area together；
In conjunction with Fig. 2, the cross section of the first lampshade 1 and the second lampshade 2 parabolically shape, the first lampshade 1 is opening down, and second
Lampshade 2 is opening up, and the opening of the first lampshade 1 is not less than the opening of the second lampshade 2, and the top of the first lampshade 1 is fixed on
On crossbeam 4, the second lampshade 2 is connected to the opening of the first lampshade 1, and the bottom of the second lampshade 2 is fixed with convex lens 5, and convex lens 5 is located at
The underface of LED lamp bead 61 is used for optically focused；The material of first lampshade 1 and the second lampshade 2 is PC plastic, in the process of actual production
In, the second lampshade 2 be located at the lower section of convex lens 5 part need to be it is transparent, the other parts of the first lampshade 1 and the second lampshade 2 can be
Transparent, translucent or opaque (can be realized by adding toner in PC plastic), when the second lampshade 2 is connected to the first lampshade
When on 1, the elasticity having by parabolic structure and PC plastic, the second lampshade 2 can be clamped on the first lampshade 1.
As shown in Figures 2 and 3, the second lampshade 2 realizes the clamping with the first lampshade 1 by card, wherein the first lampshade 1 is open
Horizontally disposed first card 11 is symmetrically arranged on the outer wall at place, and (lamp in the application is pendent lamp, therefore level herein is
Refer to that the first card 11 and following the second cards 21 are horizontal after lamp suspention, that is, are parallel to horizontal ground), the second lamp
Several the second cards 21 for the clamping of the first card 11, the first card 11 and the second card are horizontally fixed on the inner wall of cover 2
The inclined direction of piece 21 is on the contrary, i.e. the first card 11 is towards 1 outside inclined upward of the first lampshade, and the second card 21 is towards the second lampshade 2
Inside inclined downward, wherein the second card 21 is for two groups and symmetrical, every group is arranged different second of height comprising several
Card 22, and then realize that the first lampshade 1 is connected on the different location of the second lampshade 2, realize lens 5 and 61 distance of LED lamp bead
Adjustment, and then realize light beam adjustment.
In conjunction with Fig. 3, the width of the first card 11 is greater than the width of the second card 21, and (horizontal direction is the length of card in Fig. 1
Spend direction), the angle of the first card 11 and the first lampshade 1 is Ω, and the angle of the second card 2 and the second lampshade 2 is β (due to lamp
The wall of cover is curved surface, can approximately think that lampshade wall is plane when angle determines), Ω >=β, to guarantee the second card in clamping
Piece 21 can be pushed against on the first lampshade 1；When the second lampshade 2 is connected on the first lampshade 1, using the parabolic structure of lampshade,
First lampshade 1 can expand outwardly, the second lampshade 2 can to contract, and then generate two horizontal forces (such as arrow f and arrow g),
Under the action of the contraction and expansion of lampshade, two lampshades can generate movement tendency (i.e. arrow e and the arrow h) being relatively distant from；The
The junction of one card 11 and the first lampshade 1 forms contact point b, can be expanded outwardly using the first lampshade 1, and the second lampshade 2 can be to
Contract, generates the movement tendency being relatively distant from, and the first card 11 can be pushed against on the second card 21 and then form contact point a
And generating upward making every effort to promote makes the second card 21 generate bending, and the outer wall shape of the second card 21 and the first lampshade 1 is utilized at this time
The bending of the second card 21 is limited at contact point c, and then power generates counteracting, thereby reduces the bending of the second card 21, and shape
At stable three-legged structure (be respectively a, b, c), guarantee the stability of lampshade clamping at 3 points；
Further, in conjunction with Fig. 4 (force analysis figure), it is assumed that promoting two lampshades to generate the power being relatively distant from is that (F ' is F
The reaction force of F), according to force analysis it can be seen that under the active force of same size, the second card 21 is promoted to generate bending
Power F2It is less than the power F ' for promoting the first card 11 to generate bending2；If the therefore presence of non-contact-point c, in actual use,
Second card 21 is highly susceptible to bend and generate the danger of tripping, and the presence of contact point c to form gusseted at fastening,
And then guarantee stability.
As shown in Figure 4 and Figure 5, the middle part of crossbeam 4 is fixedly installed fixing sleeve 41, and LED lamp bead 61 is by being interspersed in fixation
Electric wire 6 in set 41 is suspended in the first lampshade 1, and end of the fixing sleeve 41 far from crossbeam 4 is tapered, and offers several edges
Circumferentially it is uniformly distributed notch 411 so that the end of fixing sleeve 41 forms multiple lock sheets, when installing lock sleeve 42, lock
Tight piece can shrink under the action of lock sleeve 42 and be pushed against on electric wire 6, and then realize the fixation of electric wire 6.
In use, a hand presses the first lampshade 1 and promotes it when needing for the second lampshade 2 to be mounted on the first lampshade 1
It shrinks, is then caught in the second lampshade 2, so that the first card 11 is caught on the second card of one pair of them 21, and then realize lamp
The installation of cover；When needing to change the position of the second lampshade 2, same first lampshade 1 that presses pushes the second lampshade 2,
The second lampshade 2 can be pushed directly on, the distance between final adjustable LED lamp pearl 61 and convex lens 5 change light beam.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
