A kind of angle-adjustable high-power LED ceiling lamp
Technical field
The present invention relates to a kind of lighting device, particularly relate to a kind of angle-adjustable high-power LED ceiling lamp.
Background technology
At present, no matter be in family or public place, very general with lamp decoration as decorating, high-power LED ceiling lamp mainly is the ornament that is used for decorating public places such as lounge, banquet hall, square, and in the bar desk in lively shopping plaza hall, exhibition center and bar etc., the show window of its both sides and mural painting are showed, cooperating under the light modification, seem especially noticeable is exactly because so, the collocation of light plays a part very important for setting off of environment.At present used with the pendent lamp of LED as light emitting source, though hanging structure is of all kinds,, the combination form of its lamp body is changeless basically, has tangible uniqueness, therefore, and its function singleness.And in the work of being done aspect being connected of lamp bracket structure and lamp bracket and lamp body just still less, structural change is relatively more dull, and is more fixing after the assembling.In order to prevent that the part on lamp body and the lamp bracket from coming off, such as, the syndeton of lamp bracket and lamp body mostly is to adopt locking device, even it is lamp body and lamp bracket is one-body molded, make that thus the light that sends can only penetrate toward the direction, for around or even for the ceiling, then can seem relatively dim, its decorative effect is more stiff; And adopt messenger wire directly to link to each other with lamp bracket, if meet wind, lamp bracket then can be swung with the wind, exists serious potential safety hazard; Very have adopt cylindrical or the square metal connecting rod as the syndeton between lamp bracket and the erecting by overhang, lamp body can only be arranged on the below of erecting by overhang, can not adjust angle according to actual demand, make the irradiating angle of light fixture be restricted, comparatively inconvenience in the use, seem neither attractive in appearance not generous again, more do not have individual character and can say, be not applicable to the decoration in modernized place.
Be used for controlling four control signal circuits of the general needs of driving control chip of angle-adjustable high-power LED ceiling lamp in the prior art, so when connecting with flexible cord, two input heads are generally arranged, two deliveries, each one of power connection and Signal connector, because joint quantity is more, makes that the joint fault rate is higher, reliability is lower.Adopt four signal lines to carry out cascade, the size of pcb board is had considerable restraint, for little pcb board, cause short circuit easily, problem such as go offline.The mutual interference of four signal phases causes the limited length of cascade.So hence one can see that, the combining structure of above-mentioned traditional pendent lamp in real life is used, still exists inconvenience and shortcoming, remains to be innovated and improve.
Summary of the invention
The present invention is in order to solve deficiency of the prior art, a kind of angle-adjustable high-power LED ceiling lamp to be provided especially.
Technical scheme of the present invention is:
