Abstract

The utility model relates to a high definition wordpad, wherein one edge of a transparent glass is tightly and parallel provided with a cold cathode light tube which is covered by sunshade materials, therefore the cold cathode light tube only can emit light to the transparent glass, two ends of the cold cathode light tube are connected with wires, a rectifying booster is connected with the wires, a power line is connected with the rectifying booster, a backplane of the area same as a common square transparent glass is parallel provided at the back of the transparent glass, users can write on the transparent glass and the letters contain phosphor powders, the light of the cold cathode light tube radiates the transparent glass to excite the phosphor powders in the letters to emit visible lights and make the letters more clear. The utility model can make letters emit light for high definition, having simple operation and easy use.

Description

A kind of high definition board

Technical field

The utility model relates to a kind of board, specifically a kind of high definition board that writes with the fluorescent material ink specially.

Background technology

Existing various board mainly adopts background color and other mode of ink colors phase region to show writing, as blank surplus or blackboard wrongly written or mispronounced character, and the clear line-of-sight distance with the people of writing has substantial connection, remembering that the school-days sits in the last row at lyceum is difficult to see clearly teacher's content that writes on the blackboard, open-air large-scale teaching just more need not have been said, unless write word greatly especially, and cause the reason that does not see Chu is that people's sight line has limitation, and the difficult more difference of light of scenery far away more reflection is because light light injects people's eyes but the people can see light in far place.Font itself enlightened by this, if just can luminously just can overcome the problem that does not see Chu.

The utility model content

Technical problem to be solved in the utility model provides the luminous a kind of high definition board of font itself energy on the board.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of high definition board, form by common square clear glass, cold cathode light pipe, rectification stepup transformer, backboard, lead, power line, pen, common square clear glass is an adjacent cold cathode light pipe arranged side by side on one side, cold cathode light pipe two ends are connected with lead, rectifier is connected with lead, power line is connected with rectifier, backboard is parallel with common square clear glass and be positioned at common square clear glass back, and backboard is suitable with common square clear glass area.

The further improvement project that the utility model is done is: remove adjacent common square clear glass other areas of cold cathode light pipe on one side and wrapped up by light-locking material, make the cold cathode light pipe light can only directive glass, the cold cathode optical tube length is suitable with adjacent common square clear glass one edge lengths arranged side by side, pen writes on common square clear glass, writing contains fluorescent powder, the light of cold cathode light pipe shines the fluorescent powder that excites on the common square clear glass in the writing, fluorescent powder sends visible light, writing is obviously outstanding more, the ink of pen contains fluorescent powder, and power line can be provided with power switch.

The beneficial effects of the utility model are that the writing on the board is more prone to be seen clearly Chu because of luminous, and people's eyes are not had any infringement, and is simple to operate and easy to use.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.Wherein:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a construction profile of the present utility model;

1. common square clear glasses among the figure, 2. cold cathode light pipe, 3. rectification stepup transformer, 4. light-locking material, 5. lead, 6. power line, 7. power switch, 8. backboard, 9. light, 10., 11. fluorescent powders.

The specific embodiment

The utility model is by common square clear glass 1, cold cathode light pipe 2, rectification stepup transformer 3, backboard 8, lead 5, power line 6 compositions such as grade, common square clear glass 1 is an adjacent cold cathode light pipe 2 arranged side by side on one side, cold cathode light pipe 2 two ends are connected with lead 5, rectification stepup transformer 3 is connected with lead 5, power line 6 is connected with rectification stepup transformer 3, backboard 8 and common square clear glass 1 are parallel and be positioned at common square clear glass 1 back, backboard 8 is suitable with common square clear glass 1 area, removing adjacent common square clear glass 1 cold cathode light pipe 2 other areas is on one side wrapped up by light-locking material 4, make the light 9 of cold cathode light pipe 2 can only the common square clear glass 1 of directive, cold cathode light pipe 2 length are suitable with adjacent common square clear glass 1 one edge lengths arranged side by side, pen 10 writes on common square clear glass 1, writing contains fluorescent powder 11, the light 9 of cold cathode light pipe 2 shines the fluorescent powder 11 that excites on the common square clear glass 1 in the writing, fluorescent powder 11 sends visible light, writing is obviously outstanding more, the ink of pen 10 contains fluorescent powder 11, and power line 6 can be provided with power switch 7.

When starting power switch 7, power line 6 conveys electrical current to rectification stepup transformer 3, rectification stepup transformer 3 is adjusted to cold cathode light pipe 2 needed current values with electric current, be sent to cold cathode light pipe 2 two ends by lead 5, cold cathode light pipe 2 emits beam 9, because removing adjacent common square clear glass 1 cold cathode light pipe 2 other areas is on one side wrapped up by light-locking material 4, light 9 can only the common square clear glass 1 of directive, pen 10 writes on common square clear glass 1, writing contains fluorescent powder 11, the light 9 of cold cathode light pipe 2 shines and excites the fluorescent powder 11 in the writing to send visible light on the common square clear glass 1, and writing is obviously outstanding more.

Claims
