As landscape lighting luminaire, the adjustment of ray cast angle is starved of, but the variation of lighting angle more can have influence on the ambient lighting effect.Can know from above-mentioned two China patent specification and to find out that the angular adjustment of existing Projecting Lamp can only be regulated the whole projecting angle degree of LED Projecting Lamp, and can not the illumination angle of LED Projecting Lamp be changed.Therefore, need a kind of brand-new LED Projecting Lamp structure, make said LED Projecting Lamp not only can carry out whole light projector angle and regulate, and can change the illumination angle or the illumination range of said LED Projecting Lamp.

Summary of the invention

The present invention solves that the LED Projecting Lamp is existing in the prior art can only regulate the projectional angle angle; And the problem that can not regulate illumination angle; A kind of simple in structure, angular adjustment multi-angle adjustable LED lines Projecting Lamp flexibly is provided, improves flexibility and the flexibility of lighting of the location arrangements of LED Projecting Lamp.

Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals: a kind of multi-angle adjustable LED lines Projecting Lamp, the lines LED lamp module group and the driving power that comprise support, be made up of some lines LED lamp modules; Said lines LED lamp module is arranged on the said support and with said driving power and is electrically connected; Said support comprises a hollow housing and cover plate, on said hollow housing, is provided with a lamp group installation portion and a horizontal base portion; Said lamp group installation portion is provided with some installation axle hole; Said some lines LED lamp modules independently are rotatably connected in the installation axle hole on the said lamp group installation portion, and the angle of the head and the tail installation axle hole line of said some installation axle hole and said horizontal base portion is less than 90 degree; Said driving power is connected in the said horizontal base portion.Install and separate rotation to carry out the lines LED lamp module group that crevice projection angle is regulated through the installation axle hole that on the lamp group installation portion of said support, is provided with; And the layout of said installation axle hole makes the light projection surface that said some lines led module forms and the angle of said horizontal base portion spend less than 90, thereby the projection light that forms a level or make progress at an angle.Because some lines led modules of being installed on the said support all can independently carry out the adjusting of projectional angle, so, when the angular adjustment of said lines led module is identical, can change the whole crevice projection angle of LED Projecting Lamp; Two ends are when opening gradually under the angular adjustment of said lines led module makes progress from the centre, can change the irradiating angle of LED Projecting Lamp,, can change the illumination range of said LED Projecting Lamp that is; Otherwise, can reduce the illumination range of said LED Projecting Lamp.Solved in the prior art through the present technique scheme and to have solved that the LED Projecting Lamp is existing in the prior art can only regulate the projectional angle angle, and can not be, be i.e. the illumination range problem of regulating illumination angle.

As a kind of preferred version of the present invention, said support is two, is the symmetrical configuration setting, and said some lines LED lamp modules are parallel up and down, independently be rotatably connected between the lamp group installation portion of said two supports.Said support can be one, also can be two; As adopt a support, and said some lines LED lamp modules are installed in the two ends of said support respectively, and structure is comparatively simple, but stability is not good enough.As a kind of preferred version of the present invention; Said support is made as two; Said some lines LED lamp modules are rotatably connected between said two supports, and said some lines LED lamp modules are up and down and are arranged in parallel, thereby form the projection light of certain area.In addition, said driving power is arranged between said two supports, has increased the stability of said support level seat, and the lines LED lamp module group on the said lamp group installation portion is played balanced action, make the placement of said LED Projecting Lamp more stable.

Said some installation axle hole can be straight line on said lamp group installation portion, also can be the even layout that is the camber line of concave or convex.The different arrangement forms of said some installation axle hole make said some lines LED lamp modules be installed in the illumination form that forms on the lamp group installation portion of said support and have diversity.As a kind of preferred version of the present invention; Said some installation axle hole are linearly evenly arranged on said lamp group installation portion; Form illumination projection light more uniformly, can the regulating and change of its illumination range through each lines LED lamp module group being carried out different angles.

As a kind of preferred version of the present invention, said support is L shaped, and said lamp group installation portion and said horizontal base portion are located at respectively on said two L shaped edge strips, and the angle between said lamp group installation portion and the said horizontal base portion is less than 90 degree.Said L bracket has also reduced the support material therefor when to said some lines LED lamp modules stable support being provided, and through L shaped more significantly directionality, makes the layout of LED Projecting Lamp more convenient and flexible.

As a kind of preferred version of the present invention, said driving power comprises a power shell that is provided with pass through openings, and said driving power is tightly connected through said pass through openings and said support.Described power shell adopts section bar to make, and its two ends are provided with the opening of perforation, and the horizontal base portion of this opening through said support be connected and sealed as the end cap of said driving power, has simplified the structure of driving power, has practiced thrift material.

The beneficial effect that brings of the present invention is, it is single to have solved in the prior art the existing angular adjustment of LED Projecting Lamp, and the problem that illumination range can not be regulated makes the angular adjustment of LED Projecting Lamp more flexible, various.Because the setting of L bracket; Said some lines LED lamp modules and said driving power are separately positioned on the said L shaped two ends, make said driving power and the said some lines LED lamp module groups that are installed on the said lamp group installation portion that are installed in the said horizontal base portion produce a good balance.Therefore, said multi-angle adjustable LED lines Projecting Lamp is compared LED Projecting Lamp of the prior art when having more flexible, various light projector angle adjusting, also has convenient, stable structure setting.
