Abstract

The utility model relates to an auxiliary learning tool which is convenient to write, in particular to a night writing board. The writing board comprises a transparent board body which is made of a hard material and a light-emitting device, wherein the light-emitting device comprises light-emitting diode (LED) lamp tubes which are connected in series, a switch, a wire and a storage-battery power supply, wherein the lamp tubes are arranged in a parallel mode inside the board body; the switch and the storage-battery power supply are both arranged side faces of the board body; and a transparent heat insulating layer and a transparent cushion body are arranged sequentially on the upper surface of the board body, and clamping pieces which are used for fixing paper are arranged at four top corners. Light rays emitted by the lamp tubes shine on the paper from bottom to top. Therefore shadows cannot occur, and thereby the problem of writing difficulty caused by the shadows or insufficient light rays is solved. The heat insulating layer is arranged, and therefore obvious rising of the surface temperature of the night writing board is avoided. The cushion body which is used for writing is arranged so as to be convenient to write. The board body, the heat insulating layer and the cushion body are all made of transparent materials and cannot block the light rays.

Description

The ight clipboard

Technical field

The utility model relates to a kind of study aid of conveniently writing, and relates in particular to a kind of ight clipboard.

Background technology

When write night, light source always vertical irradiation, hand or other body parts can bring shade unavoidably.So, shade or all can give to write at insufficient light and bring difficulty.Especially light source fixing the classroom in self-study at night, can not solve by changing writing position the problem of light shade.And in area relatively large classroom, there is unavoidably insufficient light or has the position of shade.Therefore, be in the classmate of this position, will run at night the problem of dysgraphia.

Summary of the invention

In order to solve the problem of the dysgraphia that shade or insufficient light cause, the utility model provides a kind of ight clipboard that can improve the paper light intensity.

The technical solution of the utility model:

A kind of ight clipboard comprises transparent plate body and the light-emitting device made by hard material; Described light-emitting device comprises LED fluorescent tube, switch, electric wire and the storage source of 15-30 series connection; Fluorescent tube is set in parallel in plate body inside, and the distance between any two fluorescent tubes is 1cm; Switch and storage source all are located at the side of plate body; The length of described fluorescent tube is that 20-22cm, its diameter are 05-0.8cm; Described plate body, its upper surface are provided with transparent thermal insulation layer and transparent pad successively, and its four drift angle places are provided with for the fixing holder of paper.During use, four angles of individual sheets are fixed with holder, then with switch opens, lamp luminescence; The light that fluorescent tube sends is radiated on paper from bottom to top, therefore shade can not occur.

For the environment that adapts to different light rays intensity and the people different requirements to light intensity, above-mentioned ight clipboard, preferred, comprise that also one is arranged on that plate body is the side, adjuster that be used for regulating lighting tube brightness.According to light intensity and the own requirement to light intensity of environment, regulate the brightness of fluorescent tube; Thereby can satisfy various brightness demands.

The beneficial effects of the utility model:

Can effectively improve the bright intensity of paper and shade can not occur, thereby having solved the problem of the dysgraphia that shade or insufficient light cause.Be provided with heat insulation layer, so the surface temperature of ight clipboard is not significantly higher, be provided with write use pad conveniently to write.Plate body, heat insulation layer and pad all adopt transparent material to make, and can not stop light.Ight clipboard of the present utility model, simple in structure, easy to use.

Description of drawings

Fig. 1 is the structural representation of ight clipboard;

In figure, 1. plate body, 2. heat insulation layer, 3. pad, 4. fluorescent tube, 5. switch, 6. storage source, 7. holder, 8. adjuster.

The specific embodiment

Further illustrate below in conjunction with accompanying drawing.

Ight clipboard of the present utility model comprises plate body 1, heat insulation layer 2, pad 3, holder 7 and light-emitting device.Described plate body 1, heat insulation layer 2 and pad 3, compound successively from below to up.Described plate body 1 is made by hard transparent material, and described heat insulation layer 2 is made by the transparent thermal insulation material, and described pad 3 is made by the soft transparent material.Four drift angle places of described plate body 1 arrange 4 holders 7 that are used for fixing paper.Described light-emitting device comprises 17 fluorescent tubes 4, switch 5, storage source 6, adjuster 8 and electric wire.Series connection between fluorescent tube 4; Switch 5 is connected between storage source 6 and fluorescent tube 4, is used for controlling fluorescent tube 4; Adjuster 8 is connected between storage source 6 and fluorescent tube 4, is used for regulating the brightness of fluorescent tube 4.Fluorescent tube 4 is the LED lamp, and length is that 20-22cm, its diameter are 05-0.8cm.Fluorescent tube 4 is set in parallel in plate body 1 inside, and the distance between any two fluorescent tubes 4 is 1cm.Switch 5, storage source 6, adjuster 8 all are located at the side of plate body 1.

Claims

1. an ight clipboard, is characterized in that, comprises transparent plate body and the light-emitting device made by hard material; Described light-emitting device comprises LED fluorescent tube, switch, electric wire and the storage source of 15-30 series connection; Fluorescent tube is set in parallel in plate body inside, and the distance between any two fluorescent tubes is 1cm; Switch and storage source all are located at the side of plate body; The length of described fluorescent tube is that 20-22cm, its diameter are 05-0.8cm; The upper surface of described plate body is provided with transparent thermal insulation layer and transparent pad successively.
