Abstract
The utility model discloses an LED lamp providing with a stepping motor and precisely changing light range, which comprises a rotating shaft, the stepping motor, a high-power LED, a moveable reflecting plane equipped with LEDs, and a fixed reflecting plane equipped with LEDs. The LED lamp is characterized in that the rotating shaft is connected on the moveable reflecting plane equipped with the LEDs, and drives the moveable reflecting plane to rotate together for precisely adjusting the light range, so as to further change the irradiation direction of the lamplight; and the stepping motor is used for automatically driving the rotating shaft to work when receiving signals sent out by a control terminal. By adopting the scheme that a stepping motor is fixed on the LED lamp, not only the lamp has simple structure, good stability and high precision, but also the technical problems in the conventional lamps that the light irradiation direction and the light range are difficult to precisely adjust can be solved.
Description
Technical field
The utility model relates to a kind of light fixture that changes illumination range, relates in particular to a kind of LED light fixture that stepper motor can accurately change illumination range that is provided with.
Background technology
The light fixture that now is used to throw light on often can not change according to user's demand aspect illumination range and irradiating angle accurately.Light fixture is in case install with regard to being difficult to accurately change light-struck angle and scope, as the lighting (garden lamp, street lamp, underground lamp, car light etc.) of existing use.And existing on the market the light fixture of performance usefulness, part is by the collocation of colour that changes light, the light on and off of light fixture, realize light-illuminating range visually, its shortcoming is: changing the light coloring collocation needs the quantity of light fixture many, its service life has been shortened in the frequent light on and off of light fixture to a great extent, design and installation complexity, financial cost height; Can not adjust the direction of illumination and the scope of light fixture in essence accurately.Therefore how with a kind of stable, practical, device changes illumination range and angle becomes the problem that prior art need solve accurately.
Summary of the invention
In order to solve the problem that illumination range under the prior art condition and angle are difficult to change, the utility model provides a kind of light fixture that stepper motor can accurately change illumination range that is provided with.
The technical solution of the utility model is: a kind ofly be provided with the LED light fixture that stepper motor can accurately change illumination range, comprise the movable reflecting surface of stepper motor, rotating shaft, great power LED, outfit LED, the fixed reflection surface of outfit LED, great power LED is fixed on the movable reflecting surface, movable reflecting surface is mounted in thereafter the rotating shaft, and stepper motor is connected to movable reflecting surface by rotating shaft.Axes of rotation skew or vertically or level be installed on the back-up block, back-up block remains unchanged with respect to the position of lamp outer casing.Fixed reflection surface is fixed with respect to lamp outer casing.Stepper motor changes movable reflecting surface by the rotation that drives rotating shaft, and then changes illumination range and lighting angle.
Stepper motor is by receiving the signal that control end sends, automatically driving rotating shaft rotates, movable reflecting surface is connected in the rotating shaft, and the accurate rotation of rotating shaft drives movable reflecting surface in a certain direction, rotate with accurate speed, and then obtains the adjustment of direction of illumination and the change of scope.
The beneficial effects of the utility model are: by having used the LED light fixture that has stepper motor, can effectively solve illumination range and angle and be difficult to the accurately problem of change, after adopting stepper motor, advantages such as noise was low when light fixture had work, stationarity good, the compact conformation volume is little adopt stepper motor and rotating shaft can change light-struck angle accurately.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated;
Fig. 1 looks schematic diagram for master of the present utility model;
Fig. 2 is a schematic rear view of the present utility model;
In Fig. 1, Fig. 2,1, rotating shaft; 2, fixed reflection surface; 3, movable reflecting surface; 4, great power LED; 5, back-up block; 6, stepper motor.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind ofly be provided with the light fixture that stepper motor can change illumination range and angle, the stepper motor 6 that comprise rotating shaft 1, fixed reflection surface 2, movable reflecting surface 3, be installed in the great power LED 4 on fixed reflection surface 2 and the movable reflecting surface 3, the back-up block 5 that is used for supporting revolving shaft 1, control rotating shaft 1 rotates.The light that fixed reflection surface 2 and movable reflecting surface 3 can both send the great power LED 4 that is equipped thereon reflects illumination is provided, the signal drive installation that the user sends by control end is at movable reflecting surface 3 stepper motor 6 behind, the drive rotating shaft is rotated, make movable reflecting surface 3 rotate with rotating shaft 1, thereby change the direction of movable reflecting surface 3, finally reach the purpose that changes illumination range and direction.
With reference to Fig. 1, a kind of light fixture that stepper motor can change illumination range that is provided with of the present utility model, rotating shaft 1 is installed on the back-up block 5, and rotating shaft also can be tilted or level is installed; Movable reflecting surface 3 is installed in the rotating shaft; Fixed reflection surface 2 is fixed with respect to lamp outer casing, can be installed in any position around the reflecting surface 3, and fixed reflection surface 2 has been fixed after the installation, and the radiation direction and the illumination range of its reflection are determined; Back-up block 5 is positioned at the two ends of rotating shaft, fix with respect to the lamp outer casing position, guarantee to be equipped with the movable reflecting surface 3 of great power LED 4 to do to become tens rotations of spending angles with respect to lamp outer casing with rotating shaft 1, corresponding change also takes place in the direction of emergent ray and illumination range.
With reference to Fig. 2, a kind of light fixture that stepper motor can change illumination range that is provided with of the present utility model, the stepper motor 6 that is positioned at movable reflecting surface 3 back changes speed by mechanical device, when stepper motor 6 work, can drive the rotation that movable reflecting surface 3 carries out tens degree angular regions, to change the purpose of illumination range.
