Abstract
The utility model discloses an universal integrating sphere test fixture. The universal integrating sphere test fixture comprises a circular locating disc. The locating disc is uniformly provided with multiple sets of installation units which are composed of several screw holes in the circumferential direction, wherein the screw holes are located on a same radius, and distances between the screw holes and the center of the locating disc are different. The locating disc is connected with a plurality of fixing supporting pieces through the screw holes and locating screws matched with the screw holes. The number of the fixing supporting pieces is the same as the number of the installation units. An electrical connecting element is fixed and arranged on the central portion of the locating disc. The universal integrating sphere test fixture of the utility model has the advantage of wide application range, is applicable to various lamps, and has the advantage of low fixture cost; and the fixture does not need to be replaced during tests, so the advantage of convenient utilization can be realized.
Description
Technical field
The utility model relates to a kind of General integral ball test fixture, belongs to light fixture field tests.
Background technology
Large-scale integration ball is the most frequently used light fixture testing apparatus, and light fixture is fixed in integrating sphere, and the illumination curve of light fixture is tested, and can carry out comparatively comprehensive, objective appraisal to the performance of light fixture.
Light fixture is often fixed in integrating sphere by test fixture, and because light fixture is all kinds of various at present, size differs, traditional integrating sphere is to fix different all kinds of light fixtures, have to prepare the fixture of a large amount of different sizes, increase testing cost, reduced the dirigibility of test.
Utility model content
The utility model, for solving prior art problem, provides a kind of universal integrating sphere measurement fixture.
The technical solution of the utility model is: a kind of General integral ball test fixture, comprise circular positioning disk, on described positioning disk, be along the circumferential direction evenly provided with some groups by several in same Radius and the installation unit that forms from screw not etc. with this positioning disk distance of center circle; Described positioning disk is connected with some fixedly supporting springs by described screw and the positioning screw that matches with this screw, and the quantity of described fixedly supporting spring equates with described installation unit quantity; The center of described positioning disk is fixedly installed electrical fitting.
As preferably, described fixedly supporting spring is curved, and the center of described arc has for connecting the through hole of described positioning screw; Described positioning screw is fixed described fixedly supporting spring by nut.
As preferably, described electrical fitting comprises the thread head that is fixedly installed on described positioning disk center, and with the external connection of this thread head electrical connection.
As preferably, described installation unit is provided with four groups.
As preferably, described positioning disk consists of the lightweight circular metal plate with described electrical fitting mutually insulated.
As preferably, described thread head is E26 thread head.
As preferably, the electrical connection of the termination of described external connection has electric folder.
The utility model fixture is mainly used at various LED Down lamps on the market, in the market LED Down lamp heat sink size, height all kinds of extremely many, the utility model is by regulating the position of positioning screw screw of living in, and by setting nut the position with respect to screw rod, can realize the fixed installation of the LED Down lamp of various height and diameter.E26 is the most frequently used lamp installation mouth, is widely used in a large amount of integrating spheres, adopts E26 as electrical fitting, applicable to more integrating spheres.And adopt the external connection of electric folder, make E26 thread head and the electrical connection of LED Down lamp more convenient, quick.
In sum, the utlity model has following advantage:
1, applied range, applicable multiple light fixture, fixture cost is low;
While 2, testing, do not need to change fixture, easy to use.
Accompanying drawing explanation
Fig. 1 is the utility model scheme of installation.
In figure, 1, positioning disk, 2, screw rod, 3, screw, 4, nut, 5, thread head, 6, fixing supporting spring, 7, LED Down lamp.
Embodiment
With embodiment, the utility model is described in further detail below.
Embodiment mono-:
A ball test fixture, comprises circular positioning disk 1, on positioning disk 1, be along the circumferential direction evenly provided with four groups by four in same Radius and the installation unit that forms from screw 3 not etc. with this positioning disk 1 distance of center circle; Positioning disk 1 is connected with four fixedly supporting springs 6 by screw 3 and the positioning screw 2 that matches with this screw 3, and fixedly supporting spring 6 is curved, and the center of arc has for connecting the through hole of positioning screw 2; Positioning screw 2 is by the fixing fixedly supporting spring 6 of nut 4.The center of positioning disk 1 is fixedly installed electrical fitting, electrical fitting comprises the thread head 5 that is fixedly installed on positioning disk 1 center, thread head 5 is E26 thread head 5, and with the external connection of this thread head 5 electrical connections, the termination electrical connection of external connection has electric folder.Positioning disk 1 consists of the lightweight circular metal plate with electrical fitting mutually insulated.
During installation, as shown in Figure 1, screw rod 2, successively through screw 3 and through hole, is put in LED Down lamp 7 to the center of positioning disk 1, the electric folder on external connection is clamped the power supply of LED Down lamp 7; Fixedly supporting spring 6 is pushed down LED Down lamp 7, and nut 4 is threaded onto on screw rod 2, and fixedly supporting spring 6 is fastening.After fixing, E26 thread head 5 is threaded onto on the threaded connector of integrating sphere.
