Description

Dazzle the LED lamp

Technical field

The utility model relates to the LED field, especially a kind ofly can provide rotating light and the LED lamp of dazzling simple in structure again.

Background technology

In the ornament lamp field, often as seen the rotation lamp holder generally is installed on dancing hall, KTV etc. and locates, it can provide the hot spot of rotation, has the good effect of dazzling, yet, this kind lamp holder is when providing the rotation hot spot, and whole lamp holder needs together rotation, therefore, the structure of its driving mechanism is comparatively complicated comparatively speaking on the one hand, damage easily, on the other hand, because rotary part is bigger, its mechanical output is also bigger, therefore comparatively power consumption.

Summary of the invention

At the problems referred to above, the purpose of this utility model is to provide a kind of LED lamp of dazzling, and this dazzles the illumination of dazzling that the LED lamp not only can provide rotation, and simple in structure, less energy intensive.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of LED lamp of dazzling, comprise wick, lamp housing, the reflection aluminium flake, drive unit, control circuit, described wick is highlighted light emitting diode, be arranged on lamp housing central authorities, the wick rear is provided with a reflection aluminium flake with smooth reflective concave surface, this reflection aluminium flake is arranged in the rotating shaft of drive unit at self rear, and the reflecting surface that should reflect aluminium flake is asymmetric, described drive unit comprises coil and iron core, iron core be shaped as three boolean's union shapes that are mutually 60 ° identical U-shaped core, coil is divided into first coil, second coil, tertiary coil, respectively on a U-shaped core, and adopt the triangle type of attachment to connect three-phase alternating current, and its direction of winding guarantees to produce rotating excitation field in iron core the place ahead behind each coil electricity, and wick connects the control circuit that is arranged on the lamp housing rear.

As preferably, the lamp housing inner surface is provided with smooth mirror surface.

As preferably, the reflection aluminium flake is a concave surface aluminium flake that is obliquely installed in rotating shaft.

As preferably, the equal turn numbers of first coil, second coil, tertiary coil, and all rotate in the direction of the clock on they pairing separately U-shaped cores.

As preferably, iron core is provided with six hoof pin, the hoof pin is towards the non-reflecting surface of reflection aluminium flake, and all with the shaft parallel that is arranged on iron core central authorities, during coil electricity, these six hoof pin promptly become six magnetic poles, two hoof pin of each U-shaped core are a pair of opposite pole, according to the characteristic of three-phase alternating current, what produce between six magnetic poles closes magnetic field and will pass the reflection aluminium flake, and constantly rotation.

As preferably, control circuit comprises rectification circuit and current-limiting resistance, and this control circuit outside connects three-phase alternating current, inner separated into two parts, and a part is by connecing described wick behind rectification circuit and the current-limiting resistance, and another part directly connects the coil in the drive unit.

The beneficial effects of the utility model are: this dazzles the LED lamp after energising, drive unit produces the rotating excitation field of passing the reflection aluminium flake, this magnetic field produces vortex flow in the reflection aluminium flake, vortex flow is had an effect with magnetic field again, the reflection aluminium flake is constantly rotated, because the reflection aluminium flake has asymmetric reflecting surface, therefore, bigger a part of radiance that it is launched the place ahead wick tilt to reflect away, and externally project asymmetric illumination or hot spot, and in the rotating process of reflection aluminium flake, it outwards the asymmetric illumination or the hot spot of projection also will be followed the rotation of reflection aluminium flake, produce and dazzle effect, whole dazzling in the LED lamp has only the rotation of reflection aluminium flake, therefore, simple in structure, not fragile, to consume mechanical energy few.
