The utility model adopts the following technical scheme:

a deformable flat panel light fixture for use in a classroom, comprising: the central illumination portion is located the central point and puts, be located four peripheral illumination portions all around of central point, central illumination portion and peripheral illumination portion are the rectangle, and one limit of peripheral illumination portion rotates with central illumination portion to be connected, and the top of central illumination portion has the lamp shade, and the lamp shade is the cube unanimous with central illumination portion shape, and the lamp shade is fixed step motor that is provided with respectively in four directions of four peripheral illumination portions, the stay cord, and one end is connected with step motor, the other end and the edge connection of peripheral illumination portion.

Further, the utility model discloses a classroom is with warping dull and stereotyped lamps and lanterns still has such characteristic: the two sides of the two symmetrical peripheral illuminating parts are provided with light blocking sheets, and when the peripheral illuminating parts are turned downwards, the light blocking sheets block the joint of the two adjacent peripheral illuminating parts.

Further, the utility model discloses a classroom is with warping dull and stereotyped lamps and lanterns still has such characteristic: the back of the peripheral illumination part is provided with a limiting rod which limits the upward turning angle of the peripheral illumination part to be on the same plane with the central illumination part.

Further, the utility model discloses a classroom is with warping dull and stereotyped lamps and lanterns still has such characteristic: wherein, the shape of gag lever post is for falling L shape.

Further, the utility model discloses a classroom is with warping dull and stereotyped lamps and lanterns still has such characteristic: wherein, the shape of the light barrier is a flat plate.

Further, the utility model discloses a classroom is with warping dull and stereotyped lamps and lanterns still has such characteristic: wherein, the shape of light barrier is L shape.

Further, the utility model discloses a classroom is with warping dull and stereotyped lamps and lanterns still has such characteristic: the back edge of the peripheral illumination part is provided with a fixing ring, and the pull rope is fixed on the fixing ring.

The beneficial effects of the utility model are that, the utility model discloses a classroom is with warping dull and stereotyped lamps and lanterns is in the expansion state when not using the projecting apparatus, can regard as the flat lamps and lanterns of classroom conventional illumination to use. When the projector is used, the four peripheral illuminating parts are put down to form a spotlight state, and illumination is only performed in the desk range below the lamp. The desk has small influence on illumination of a projector picture at the platform, so that the desk is effectively illuminated while the projector is used.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1, 2 and 3. A deformable flat panel light fixture for use in a classroom 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.

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.

Stepping motors 14 are fixedly provided to the four directions of the lamp housing 14 and the four peripheral illumination portions 12, respectively. One end of the pull cord 16 is connected to the stepping motor, 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 14 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 illuminating part 12, when the switch of the stepping motor 14 is pneumatic in the other direction, the stepping motor rotates backward to release the pull rope to put down the peripheral illuminating part 12 until the state of the spotlight as shown in fig. 3 is achieved.

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.
