Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1, 2, 3 and 4. Deformable light fixture for classroom use comprising: the central illumination portion 11 is located at the center, the four peripheral illumination portions 12 are located at the four sides of the center, and the central illumination portion 11 and the peripheral illumination portions 12 are rectangular.
One side of the peripheral illumination unit 12 is rotatably connected to the central illumination unit 11 via a rotation shaft 23.
As shown in fig. 2, a globe 14 is provided above the central lighting unit 11, and the globe 14 has a cubic shape conforming to the shape of the central lighting unit. The lamp housing 14 is mounted to the ceiling of a room by means of mounting posts 18.
The four directions of the lampshade 14 and the four peripheral illuminating parts are respectively provided with a pulley 20, the top center inside the lampshade 14 is fixedly provided with a stepping motor 15, and the stepping motor 15 extends out of the motor shaft downwards.
One end of the pull rope 16 is fixedly connected with a motor shaft of the stepping motor 15, one end is connected with the stepping motor 15, and the other end is wound on the pulley 20 and then connected with the edge of the peripheral illumination part.
One end of the pull cord 16 is connected to the stepping motor 15, and the other end is connected to the edge of the peripheral illumination section 12. The peripheral illumination portion 12 has a fixing ring 17 at its edge, and the pull cord 16 is fixed to the fixing ring 17. Of course, in other embodiments, the fixing of the string to the edge of the peripheral illumination portion 12 may be performed by bolt fixing or welding. The fixing ring 17 is adopted for fixing, and the beneficial effect is that the pull rope is convenient to replace in the later maintenance.
The stepping motor 15 and the lighting part of the lamp respectively adopt different wall switches, and the lighting and the motor electrification are controlled through two lines. The light switch is a form of switch commonly used in the art and will not be described in detail herein. The switching of the stepper motor 14 is also a common form. When the switch of the stepping motor 14 is twisted in one direction, the stepping motor rotates forward to drive the pull rope to pull up the peripheral illumination part 12, when the switch of the stepping motor 14 is twisted in the other direction, the stepping motor rotates backward to release the pull rope to put down the peripheral illumination part 12 until the spotlight state shown in fig. 3 is achieved. The utility model discloses only use a step motor can accomplish the lift operation to four periphery illumination portions, the cost is reduced on the one hand, and on the other hand is still more energy-conserving.
The lower end of the motor shaft of the motor 15 is provided with a stopper 22 which is disposed perpendicular to the motor shaft to prevent the pulling rope 16 from being pulled out from the lower end of the motor shaft when wound.
The back of the peripheral illuminating part 12 is provided with a limiting rod 19, and the limiting rod 19 limits the upward turning angle of the peripheral illuminating part to be on the same plane with the central illuminating part. The limiting rod is in an inverted L shape, the distance between the limiting rod and the rotating shaft is short, when the peripheral lighting part turns upwards to the same horizontal plane as the central lighting part, the transverse part on the L shape just abuts against the upper surface of the lampshade 14, and therefore the peripheral lighting part is limited to continue to turn upwards.
As shown in fig. 1, both sides of two peripheral illuminating portions symmetrical to each other have light blocking sheets 13, and when the peripheral illuminating portions 12 are turned downward, the light blocking sheets 13 block at the seams of two adjacent peripheral illuminating portions. Typically one of the sets of light barriers 13 should be located on the peripheral illumination portion of the side facing the projector picture to further reduce light emanating therefrom and to reduce light interference with the projector picture. As shown in fig. 3, the light blocking sheet 13 may be a flat plate, as shown in fig. 4, the light blocking sheet may also be an L-shaped sheet, and preferably, the L-shaped sheet may block light exposed in another direction.
