Description
Technical field
The utility model relates to a kind of lighting apparatus, particularly a kind of light fixture with rotary spacing function.
Background technology
Compare traditional lighting light fixture, LED light fixture has advantages of that energy consumption is low, light efficiency is high, and therefore LED light fixture is applied rapidly.In order to realize adjustment illumination zone, generally need to adopt rotating mechanism to meet the requirement of different field of illuminations.Light fixture of the prior art generally adopt between securing member and clamp nut sandwiched pad or helical spring locked to prevent this securing member.And generally by tightly firmware of light fixture outer buttons, and tighten the clamp nut coordinating with this securing member in lamp interior, need first by after securing member and clamp nut installation just this installation component be arranged on other fitting structures, make installation process more loaded down with trivial details and be not easy to the installation of closed lamp body.In addition, in general illumination occasion, need the rotational angle of such light fixture to be limited, to prevent that light fixture from significantly rotating and the parts of excessive damage light fixture.But light fixture of the prior art is generally subject to stopping of lamp bracket or lamp body by lamp body and is subject to the slewing area that body of wall, cupboard etc. in installation environment stop to limit this lamp body mutually.Therefore, such light fixture needs installation environment or the lamp bracket of corresponding construction design to realize rotary spacing with cooperation, thereby has limited range of application and the free design space of light fixture.In prior art, also there is light fixture to adopt other outer position-limit mechanisms that are located at light fixture two ends to realize the light fixture of its rotary spacing, but such position-limit mechanism complex structure and do not there is the succinct effect attractive in appearance of entirety.
Summary of the invention
In view of this, the utility model provides a kind of easy for installation and can within the scope of certain angle, rotate to adjust the light fixture of range of exposures, to solve the problems of the technologies described above.
A kind of light fixture, comprises a support with two connecting portions that are oppositely arranged, and two are separately positioned on the end cap at described light fixture two ends, and two wear respectively the securing member of described connecting portion and described end cap.Described end cap offers the internal thread coordinating with described securing member.Described light fixture also comprises two spacing shims that are fixedly installed on respectively on described connecting portion that are located in successively on described securing member and between this securing member and the internal thread of described end cap, two respectively with the co-rotational rotating gasket of described end cap, two contact respectively the bullet pad that prevents that described securing member is locked with described rotating gasket point.Described end cap axially offers an accommodating cavity along described securing member.Described bullet pad is slidably arranged in described accommodating cavity.Described rotating gasket is fixedly installed in described accommodating cavity and is provided with at least one along the axial restraint of described securing member protrudes limiting section.Described spacing shim offers around the central shaft of described securing member at least one coordinates the rotational angle that limits this rotating gasket stopper slot with this protrusion limiting section.
Compared with prior art, the utility model light fixture is opened on end cap the screw thread coordinating with securing member to substitute nut, thereby need to be at lamp interior fastening nut, and then facilitates fitting operation.And prevent that by adopting bullet pad to contact with the point of rotating gasket securing member is locked, rotate with respect to described support taking described securing member as axle and realize described end cap.And bullet pad is less along the axial width of described securing member, the degree of depth that therefore makes to be opened in the accommodating cavity on end cap does not need too dark, can reduce the thickness of end cap to save space and material.And realize within the specific limits adjustable of light fixture irradiating angle the coordinating of the stopper slot of the protrusion limiting section having by rotating gasket and described spacing shim.Above-mentioned modular construction is simple, size is less, is contained in the accommodating cavity of end cap and for the connecting portion of support is blocked, thereby conveniently manufactures, saving cost and having preferably succinctly and the strong effect of globality.
