Abstract
The present invention provide a kind of can global flag blackboard, including in most front side transparency carrier, the transparency carrier surface is available for chalk and writes；The rear side of the transparency carrier is provided with one layer of luminous plate；The luminous plate is red or green luminous plate；The glow color identical color filter plate of one layer and luminous plate is additionally provided between luminous plate and transparency carrier.The blackboard can allow laser flashlight carry out global flag, so as to improve teaching convenience.
Description
Technical field
The present invention relates to realia field, especially, is related to a kind of blackboard.
Background technology
Blackboard is realia the most basic, and at present in teaching process, generally using laser flashlight on blackboard
Content remotely indicated；This facilitate that teacher is being given lessons under blackboard larger distance；However, laser flashlight can only
Form, on blackboard, the hot spot that a hot spot follows laser head to move, can not make marks on common blackboard；Obviously, impart knowledge to students
Convenience has still been short of.
Content of the invention
For the problems referred to above, it is an object of the invention to provide a kind of can global flag blackboard, the blackboard can allow sharp
Light torch carries out global flag, so as to improve teaching convenience.
The technical solution adopted for the present invention to solve the technical problems is：This can the blackboard of global flag include before most
The transparency carrier of side, the transparency carrier surface are available for chalk and write；The rear side of the transparency carrier is provided with one layer of luminous plate.
Preferably, the rear side of the luminous plate is provided with a layer depth color base plate, to set off the white powder that is write on blackboard
Word.
Preferably, the luminous plate is red or green luminous plate；One layer is additionally provided between luminous plate and transparency carrier
Glow color identical color filter plate with luminous plate；So that light and daylight are declined to a great extent for the impact of luminous plate, and not
The glow color identical laser flashlight of impact and luminous plate is for the effect of luminous plate；Further, on rear side of the luminous plate
One layer of minute surface is additionally provided with, so that the aura formed on luminous plate all invests front, to improve the brightness of optical markings.For this
Preferred version, the present invention also provide a kind of laser flashlight, and the laser flashlight can provide two different colors of laser rays, and only
One of which laser rays is identical with the color of the color filter plate；The laser flashlight is also configured with for described two kinds different face
The switching switch of the laser rays of color, makes the laser flashlight synchronization get a kind of laser rays of color；Described two kinds
The laser rays of different colours is parallel to each other, and is smaller than 1cm.
Above-mentioned can the beneficial effect of blackboard of global flag be：In teaching process, using laser flashlight to the blackboard
It is irradiated where mark needed for upper, then the intensity of the laser rays for being produced due to laser flashlight is much larger than ambient lighting, therefore,
Obvious aura will be formed on luminous plate where laser rays is passed slowly, and the path of the aura constitutes required mark；
As can be seen here, the blackboard can allow laser flashlight carry out global flag, to improve teaching convenience.
Description of the drawings
Fig. 1 be originally can global flag blackboard embodiment one schematic diagram.
Fig. 2 be originally can global flag blackboard embodiment two schematic diagram.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples：
Embodiment one：
In the embodiment one shown in Fig. 1, this can global flag blackboard include in most front side transparency carrier 1, described
1 surface of bright substrate is available for chalk and writes；The rear side of the transparency carrier 1 is provided with one layer of luminous plate 2；The rear side of the luminous plate 2
A layer depth color base plate 3 is additionally provided with, to set off the white letter written with chalk that is write on blackboard.
Blackboard in the present embodiment one in teaching process, using laser flashlight to entering where mark needed on the blackboard
Row irradiates, and e.g., for the keyword of required line, laser rays can be made slowly to be moved in the lower section of the keyword from left to right；
The intensity of the laser rays for then being produced due to laser flashlight is much larger than ambient lighting, therefore, passes slowly in laser rays on luminous plate 2
Where will form obvious aura, the path of the aura constitute needed for mark；As can be seen here, the blackboard can allow laser
Torch carries out global flag, to improve teaching convenience.
Embodiment two：
In the embodiment two shown in Fig. 2, this can global flag blackboard include in most front side transparency carrier 1, described
1 surface of bright substrate is available for chalk and writes；The rear side of the transparency carrier 1 is provided with one layer of luminous plate 2；The luminous plate 2 is redness
Or green luminous plate；And between luminous plate 2 and transparency carrier 1, it is additionally provided with the glow color identical colour filter of a layer and luminous plate 2
Plate 4；So that light and daylight are declined to a great extent for the impact of luminous plate 2（In the ambient lights such as light, daylight, shared by monochromatic light
Intensity very small）；And do not affect the work with the glow color identical laser flashlight of luminous plate 2 for luminous plate 2
With（Laser flashlight produces strong monochromatic light）.Further, since the presence of the color filter plate 4, it is no longer necessary to the dark color in embodiment one
Base plate 3, you can set off the white letter written with chalk on blackboard.In the present embodiment two, 2 rear side of the luminous plate is additionally provided with one layer of minute surface 5,
So that the aura formed on luminous plate 2 all invests front, to improve the brightness of optical markings.
The present embodiment two is directed to, the present invention also provides a kind of laser flashlight, the laser flashlight can provide two kinds of different face
The laser rays of color, and only one of which laser rays is identical with the color of the color filter plate 4；It is right that the laser flashlight is also configured with
Switch in the switching of described two different colors of laser rays, make the laser flashlight synchronization get a kind of color
Laser rays；Described two different colors of laser rays is parallel to each other, and is smaller than 1cm.For the laser flashlight, it is being not required to
When being marked to the content on blackboard, then can be indicated using the laser rays different from 4 color of the color filter plate, then
The laser rays cannot pass through color filter plate 4, it is impossible to so that luminous plate 2 below is lighted, so as to forming optical markings on blackboard；
And after the laser rays different from 4 color of color filter plate moves to the original position of required mark, switch to face identical with color filter plate 4
The laser rays of color, then accurately can be marked to the key content on blackboard, to avoid laser rays from moving to mark
Original position before, just on blackboard haul out optics vestige（Although thin）.
In addition, it is noted that laser flashlight usually said at present, actually not sharp in real physical meaning
Light device, is typically made up of the lens group of monochromatic highlighted LED wafer and its front, actually by monochromatic highlighted LED wafer institute
The monochromatic light of generation is converged forward to be in line and is formed.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
Within principle, any modification for being made, equivalent, should be included within the scope of the present invention.
