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.Find out as can be known that from above-mentioned two China patent specification 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 described 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 described 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 the flexibility of location arrangements of LED Projecting Lamp and the flexibility of lighting.

Above-mentioned technical problem of the present invention is mainly solved by 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; Described lines LED lamp module is arranged on the described support and with described driving power and is electrically connected; Described support comprises a hollow housing and cover plate, is provided with a lamp group installation portion and a horizontal base portion on described hollow housing; Described lamp group installation portion is provided with some installation axle hole, described some lines LED lamp modules independently are rotatably connected in the installation axle hole on the described lamp group installation portion, and the angle of the head and the tail installation axle hole line of described some installation axle hole and described horizontal base portion is less than 90 degree; Described driving power is connected in the described horizontal base portion.Install and separate rotation to carry out the lines LED lamp module group that crevice projection angle is regulated by the installation axle hole that on the lamp group installation portion of described support, is provided with, and the layout of described installation axle hole makes the light projection surface that described some lines led module forms and the angle of described 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 described support all can independently carry out the adjusting of projectional angle, so, when the angular adjustment of described lines led module is identical, can change the whole crevice projection angle of LED Projecting Lamp; When the angular adjustment of described lines led module from the centre up and down two ends be when opening gradually, can change the irradiating angle of LED Projecting Lamp, that is, can change the illumination range of described LED Projecting Lamp; Otherwise, can reduce the illumination range of described LED Projecting Lamp.Solved in the prior art by the technical program 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 preferred embodiment of the present invention, described support is two, is the symmetrical configuration setting, and described some lines LED lamp modules are parallel up and down, independently be rotatably connected between the lamp group installation portion of described two supports.Described support can be one, also can be two; As adopt a support, and described some lines LED lamp modules are installed in the two ends of described support respectively, and structure is comparatively simple, but stability is not good enough.As a preferred embodiment of the present invention, described support is made as two, described some lines LED lamp modules are rotatably connected between described two supports, and described some lines LED lamp modules are up and down and are arranged in parallel, thereby form the projection light of certain area.In addition, described driving power is arranged between described two supports, has increased the stability of described support level seat, and the lines LED lamp module group on the described lamp group installation portion is played balanced action, make the placement of described LED Projecting Lamp more stable.

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

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

As a preferred embodiment of the present invention, described driving power comprises a power shell that is provided with pass through openings, and described driving power is tightly connected by described pass through openings and described 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 by described support be connected and sealed as the end cap of described driving power, has simplified the structure of driving power, has saved 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, described some lines LED lamp modules and described driving power are separately positioned on the described L shaped two ends, make described driving power and the described some lines LED lamp module groups that are installed on the described lamp group installation portion that are installed in the described horizontal base portion produce a good balance.Therefore, the LED Projecting Lamp of described multi-angle adjustable LED lines Projecting Lamp in compared to existing technology also has convenient, stable structure setting having when more flexible, various light projector angle regulates.
