Abstract
The utility model relates to a reflecting-proof blackboard with a light source, which is composed of a panel made of light conducting material such as glass, organic glass, a plastic plate with high transparency or a fibre-optic plate, etc., a tie plate, edge frames which are installed on the peripheries of the panel and the tie plate and are provided with a light source and a reflecting plate. The outline form of the utility model is similar to that of a common blackboard; because the light source is arranged in the edge frame and irradiates the blackboard by carrying out sidelight and is matched with the reflecting plate, the blackboard can achieve the effect of no reflecting no matter seeing from any angles. The utility model has bright and clear panel, and can prevent students' vision and enhance teaching quality. The utility model is especially suitable for classroom with insufficient light ray at cloudy day or at night. The utility model can also be applied to occasions such as advertisement columns, newspaper columns, etc.
Description
The utility model belongs to school supply and stationery, is a kind of reflection prevention blackboard with light source.
Various, each has something to recommend him at the blackboard type of various occasions uses at present, all there is defective in varying degrees.Especially for the blackboard of teaching, though several times improve to upgrade, but still exist than distinct issues: at first be dark, especially in bad weather, perhaps class hour in the top class in a kindergarten, it is gruelling to look at the blackboard away from the place of blackboard, even does not see.It not only influences teaching efficiency, and causes myopia of student easily.Next is reflective, among the student who looks at the blackboard from different perspectives, always has a certain angle not see writing on the blackboard, be shifted temporarily and just can see writing on the blackboard clearly.Especially top class in a kindergarten's impact effect especially on class.
The purpose of this utility model is at present teaching with existing topic of blackboard, design a kind of simple in structure, easy to use, plate face light is clear, the band light source of no-reflection phenomenon, reflection prevention blackboard.
The purpose of this utility model reaches by following measure:
A kind of reflection prevention blackboard of the band light source of forming by panel, frame and backing plate, it is characterized in that adopting panel that optical material makes and backing plate around the frame of band light source and reflector is housed.
This reflector can replace with the inboard burnishing surface of stainless steel frame when frame adopts stainless steel to make, and when frame adopts plastic production, can replace with the inboard metal-plated membrane of plastic frame; Parabola reflecting metal plate or reflective metal film can also be housed in frame.The light source of employing fluorescent lamp or white light source lamp also can select three sides or two sides or the side that are put in blackboard arbitrarily around can being positioned over blackboard along frame.The material of making panel can adopt glass or lucite or optical materials such as high grade of transparency plastic plate or fibre optic plate.
The utility model is compared with existing blackboard has following outstanding advantage:
1, profile and normal blackboard are similar, and light source carries out the sidelight irradiation at frame to blackboard, improves the brightness of plate face, thereby has improved the definition of writing on the blackboard.
2, because panel adopts glass or lucite, or making such as high grade of transparency plastic plate or fibre optic plate, so can inspire high brightness.It is under the cooperation of light source and reflector, and no matter from what angle looking at the blackboard to reach the effect of no-reflection.
3, can set what and size of light source according to actual service conditions, convenient and reasonable.
4, be with the reflection prevention blackboard of light source, can reduce the fatigue of student's eyes, vision protection is improved the quality of teaching.Be specially adapted to the classroom of insufficient light, cloudy day or evening.
5, the utility model can also be applied to occasions such as advertisement, newpapers and periodicals hurdle.
Fig. 1 is the structural representation of the reflection prevention blackboard of band light source;
Fig. 2 is the circular frame cross section structure schematic diagram of the reflection prevention blackboard of band light source;
Fig. 3 is the square frame cross section structure schematic diagram of the reflection prevention blackboard of band light source.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is further described:
As shown in Figure 1,1 is the panel of blackboard among Fig. 1, and it can adopt optical materials such as glass or lucite or high grade of transparency plastic plate or fibre optic plate to make.Equitant with panel 1 is the backing plate 3 of blackboard, and it can adopt plank or plastic opaque plate or sheet metal to make.Be equipped with around the backing plate 3 of blackboard and the panel 1 by stainless steel or plastics etc. make, cross sectional shape can be the frame 2 of circular, square or rectangle, ellipse etc.When frame 2 is that the inboard can metal-plated membrane when making for plastic material; When frame 2 was the stainless steel making, the inboard must be a burnishing surface.The 4th, light source.
The partial enlarged drawing of circular frame cross section structure as shown in Figure 2.The panel 1 of blackboard and backing plate 3 are inserted on the framework of circular frame 2 among the figure, light source 4 is housed in the framework of circular frame 2 light source side illumination is penetrated, and do not have outer exposure.Circular frame 2 can be a stainless steel products, and its inboard is a burnishing surface.Circular frame 2 can also be plastic products, and its inboard then needs metal-plated membrane.Light source 4 can be fluorescent lamp or white light source lamp, can be positioned over blackboard along frame 2 around, also can put three sides or bilateral or any side.Place what of light source, decide by the daylighting situation of actual field of employment.
The partial enlarged drawing of square frame cross section structure as shown in Figure 3.The panel 1 of blackboard and backing plate 3 are inserted on the framework of square frame 2 among the figure, and parabola reflecting metal plate 5 or reflective metal film 5 are housed in the framework of square frame 2, in reflecting metal plate (film) 5 light source 4 are housed.Light source 4 can be fluorescent lamp or white light source lamp, can be positioned over blackboard along frame 2 around, also can select three sides or two sides or the side that are put in blackboard arbitrarily.Relation between other structure and the structure thereof is with embodiment 1.
Claims (5)
