Embodiment
As shown in the figure, the utility model comprises the unit that is in the light, lamp installation unit and elevating mechanism.
The unit that is in the light of light fixture comprises baffle plate 12 and baffle plate slot 7, and baffle plate 12 has two kinds of structures, is respectively at the circular baffle plate of circular luminaire with at the square baffle plate of square light fixture.When light fixture is circle, select the circular baffle plate of same diameter perforate for use according to the light-emitting area diameter of circular luminaire, insert baffle plate slot 7 and get final product.When light fixture when being square, insert successively in the baffle plate slot 7 according to the order of lower baffle plate 124, right baffle-plate 122, right baffle plate 123, after treating that lamp installation finishes, insert overhead gage 124 at last, according to the perforate size that the light-emitting area of square light fixture is regulated square baffle plate, guarantee that the light-emitting area of square light fixture can be exposed in the perforate fully.The inwall of baffle plate 12 adopts the coating identical with integrating sphere, reduces the absorption of 12 pairs of light fixture luminous fluxes of baffle plate.
After baffle plate 12 installs, just can begin light fixture has been installed.
The lamp installation unit comprises light fixture depression bar 17, location wedge 18, light fixture support bar 19, wedge chute 20, depression bar set nut 21, and wedge set nut 22.When light fixture is installed, light fixture is placed between two pairs of location wedges 18, and the edge of the light-emitting area of light fixture is placed on the light fixture support bar 19.Regulate the spacing of two wedge chutes, make the lamp luminescence face perpendicular to surface level.Regulate simultaneously over against location wedge 181 and location wedge 182, location wedge 183 and location wedge 184, the light-emitting area of light fixture is exposed in the perforate of baffle plate 12.Tighten wedge set nut 22 and depression bar set nut 21 at last, guarantee that lamp installation is stable.
Regulate the height of hoistable platform 6 according to the height of integrating sphere 2 π openings, the perforate of baffle plate 12 and the aperture position of integrating sphere 2 π are matched.
Pedestal and lifting unit branch comprise pulley 1, clamp base 2, and rising button 3, decline button 4, power switch 5, pushes away handle 8, guide pole 9, lifting screw 10 and goes up locating rack 11 hoistable platform 6.In pedestal 2 inside a motor is arranged, turn on the power switch 5, press rising button 3 or decline button 4 according to the position of integrating sphere 2 π openings, then lifting screw 10 will forward rotation or backward rotation, thereby drive hoistable platform 6 and under the restriction of four guide poles 9, do rising or descending motion, baffle plate 12 position of opening and integrating sphere 2 π openings are matched.Last locating rack 11 is fixed four guide poles 9 and lifting screw 10, makes this five bar keeping parallelisms, thereby reduces the resistance of hoistable platform 6 in process of rising or falling.Firmly push-and-pull pushes away handle 8, and then whole test fixture can be arbitrarily mobile under the support of four pulleys 1.This structure that can lifting is fit to the integrating sphere of various models.
The above is the utility model preferred implementation only, is not to limit practical range of the present utility model, and the equivalence of doing in protection domain of the present utility model changes and modifies in every case, all should think to have fallen in the protection domain of the present utility model.
