The specific embodiment
In order to make technical problem to be solved by this invention, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Please in the lump referring to figs. 1 through Fig. 5, the existing light fixture focusing structure that invention is provided describes.Described light fixture focusing structure is located between the electric box 2 and outer reflector 3 of Gao Dingdeng, comprises focusing body 11 and an annular rotary table 12, and described focusing body 11 is fixedly connected with described electric box 2, and described rotating disk 12 is fixed at the afterbody of the outer reflector 3 of Gao Dingdeng; Described focusing body 11 is hollow structure, its side is provided with at least one group of notch and at least one neutral section 114, each is organized described notch and comprises at least three focusing gear grooves 111 that vertically distribute, the inboard of described rotating disk 12 be provided with can with the clamping boss 121 of described focusing gear groove 111 clampings; On described rotating disk 12, also be provided with the latch assembly 13 that tightens for described rotating disk 12 and described focusing body 11.
Light fixture focusing structure provided by the invention, match with the annular rotary table 12 that is provided with clamping boss 121 and latch assembly 13 by the focusing body 11 that is provided with focusing gear groove 111, control beam angle and brightness value in conjunction with outer reflector 3 again, can make light fixture produce optically focused, three kinds of different light distribution effects of medium luminous intensity distribution and floodlight, thereby realize that a desk lamp tool can be used in the different situations under multiple occasion or the same occasion, satisfies lighting demand under the different operating positions; Simultaneously, this focusing structure so that the focusing of light fixture is simple to operate, quick and accurately.
Further, see also Fig. 2, Fig. 4 and Fig. 5, a kind of optimization embodiment as light fixture focusing structure provided by the invention, described notch is made as two groups, and rightabout is symmetric in the outside of described focusing body 11, described neutral section 114 also is two, and described clamping boss 121 is made as two and be symmetric in described rotating disk 12 inboards.In the present embodiment, it is symmetrical that its notch and clamping boss 121 are circumference, and the stress balance that can be rotating disk 12 after focusing body 11 blocks is difficult for to one side lateral deviation and loosening or come off, so that the focusing positioning stablity of light fixture and accurately.
Further, as a kind of optimization embodiment of light fixture focusing structure provided by the invention, each organizes described notch shared circumference radian on the outer circumference of described focusing body 11 is 45 °～60 °.The purpose of design is like this: on the one hand, in order just not allow clamping boss 121 aim at neutral section 114 and the realization gearshift of focusing body 11 so that rotating disk 12 does not need to rotate very large angle, on the other hand, also in order clamping boss 121 to be done to get wider steadiness to guarantee to connect, so also need with neutral section 114 arrange the wider clamping boss 121 that just can allow by deviating from, to realize gearshift; So, the radian that focusing gear groove 111 takies in the circumference side of focusing body 11 should not be too large; In the present embodiment, the radian that focusing gear groove 111 is taken in the circumference side of focusing body 11 is made as 45 °～60 °, so that each the focusing when shifting gears only needs rotating disk 12 is rotated 45 °～60 ° with respect to focusing body 11, just another gear of precession as required is swift to operate.
Further, referring to Fig. 2 and Fig. 4, a kind of specific embodiment as light fixture focusing structure provided by the invention, each focusing gear groove 111 of organizing described notch is set to three, is followed successively by from front to back optically focused gear groove 1111, medium luminous intensity distribution gear groove 1112 and floodlight gear groove 1113 on vertically.In the present embodiment, the best fit position of rotating disk 12 on focusing body 11 when adjusting out by experiment generation optically focused, medium luminous intensity distribution, three kinds of light efficiencies of floodlight, and leave the gear groove in these three positions respectively; Like this, when focusing at every turn, only need as required light efficiency with the clamping boss 121 on the rotating disk 12 and corresponding focusing gear groove 111 corresponding block mutually to screw get final product, simple, convenient, quick.
Further, see also Fig. 5 to Fig. 7, as a kind of specific embodiment of light fixture focusing structure provided by the invention, described latch assembly 13 comprises handle 131, compact heap 132 and lock bracket 133; Described lock bracket 133 is located on the described rotating disk 11 and is comprised a vertical portion 1331 and a parallel portion 1332, is provided with a step-like through hole 1330 in described vertical portion 1331; Described compact heap 132 has the less tapered end 1322 that pushes against with described focusing body 11 of being used for, and the tapered end 1332 of described compact heap 132 is actively located in described step-like through hole 1330 and exposes to the inner port of described step-like through hole 1330; The inner of described handle 131 is the eccentric cam structure, and the inner of described handle 131 is rotated and is located between the parallel portion 1332 and described rotating disk 11 of described lock bracket 133, and the inner of described handle 131 and described compact heap 132 offset.In the present embodiment, Eccentric earn mechamism on the dependence handle 131 is realized the compression of compact heap 132 and is unclamped, the tapered end 1322 of compact heap 132 compressed focusing body 11 when handle 131 was pressed, pulling handle 131, compact heap 132 unclamps focusing body 11, at this moment, rotating disk 12 just can turn round and open and shift gears; After finishing changing shelves, set lever 131 again, prevent from becoming flexible; Certainly, handle 131 also plays the effect of spanner when rotating.
Further, see also Fig. 5, on the basis of the technical scheme of a upper embodiment, a kind of optimization as light fixture focusing structure provided by the invention, described latch assembly also comprises elastomeric element 134 and pressure pad 135, described elastomeric element 133 is located between described compact heap 132 and the described lock bracket 133, and described pressure pad 135 is located between the inner of described compact heap 132 and described handle 131.In the present embodiment, by setting up elastomeric element 133, like this, when handle 131 unclamps compact heap 132, under the elastic force effect of elastomeric element 133, can guarantee that compact heap 132 all leaves focusing body 11 automatically at every turn, avoid occurring in the step through-hole 1330 that compact heap 132 is stuck in focusing support 133 and can not realize getting loose between rotating disk 12 and the focusing body 11 and can't turn round; Pressure pad 135 can play cushioning effect between handle 131 and compact heap 132, avoid inner directly the contact with compact heap 132 these two hard parts of handle 131 to produce friction and wear and tear, thus the service life of assurance parts.
