Abstract

The utility model relates to a zigzag refractive glass, wherein, one face of the utility model relates to a plane face, and the other face relates to a zigzag face. The utility model is characterized in that the angle between the inclined face of the zigzag face and the plane face relates to 45 DEG; zigzag depth distance is equal to opening distance, in which case a wedge-shaped notch forms a isosceles right triangle. The utility model has the advantages that the utility model can be used as windows of a building which can effectively prevent the damage to people's study or work due to direct sunlight and enable the light in the room much comfortable, and furthermore, the utility model can be used as glass of windows of office buildings, schools, families, etc.

Description

The spination dioptric glass

The utility model relates to a kind of dioptric glass, particularly a kind of dioptric glass of a surperficial indentation.

Glass is used widely in all trades and professions at present.Particularly the window of various buildingss adopts flat glass nearly all unlimitedly.Though to improving indoor illuminance good effect is arranged, " light pollution " problem that it brings is also more and more outstanding.For example, in office or classroom, when intensive sunlight direct projection window-glass shone on desk or the desk, forceful rays will be very dazzling, and influence is handled official business and study, be in for a long time in this environment to cause myopia, so that colour blindness.Particularly the intensive solar ray also can damage people's spirit, health.For reducing the injury that sunlight directly causes human body, also have many tinted shades to be used for architectural window at present, but its cost is than the simple glass height; Also there are the curtain of use, window shutter to wait and stop the light point-blank, but can influence illuminating effect.

The purpose of this utility model provides and a kind ofly can reduce the light direct projection effectively and do not influence the dioptric glass of illuminating effect.

The purpose of this utility model realizes by following technical solution:

Dioptric glass described in the utility model simultaneously be plane, one side for the spination face, the horizontal plane that is characterized in toothed surfaces and the angle theta on its inclined-plane are that 45 ° and its tooth deep distance equate with the opening distance, make its wedge-formed incision constitute an isosceles right-angle triangle.

The utility model has the advantages that, when with its toothed surfaces to outside window, when install in window on the plane, then there is solar radiation to arrive this when on glass outside window, because its toothed surfaces is made up of some positive bevelled mirrors, therefore, under its effect, part sunlight will be reflected outside the exit window, and its refracted ray will be folded to the top ceiling direction by the plane and reflex to indoor space through top ceiling again; Under the effect of indoor " dust ", form diffusion, make indoor illumination soft.The harm that causes with regard to the direct projection that has prevented sunlight more effectively makes indoor illumination become even relatively like this, and light intensity weakens relatively.Help people's working and learning.

Below in conjunction with an embodiment the technical solution of the utility model is described further:

Fig. 1 is a perspective view of the present utility model;

Fig. 2 is that principle of work synoptic diagram is looked local on the right side of Fig. 1.

1 is the dioptric glass body in Fig. 1, and its back side 4 is the plane, and the front is a toothed surfaces, and this toothed surfaces is made of inclined-plane 2 and horizontal plane 3, and the angle theta between the two (referring to Fig. 2) is 45 °.In Fig. 2, the horizontal plane tooth deep distance of its toothed surfaces is AB, and the opening distance of opening surface is AC, and AB=AC is arranged.Each wedge-formed incision (△ ABC) formation isosceles right angle three that is its toothed surfaces is tangible, and for preventing injury, its tooth-like part is made fillet.During use, with the toothed surfaces of this dioptric glass to outside window, the plane window of in window, packing into, as being reference plane with the horizontal plane, when sunlight (the K light among the figure, α angle) with the time greater than 45 directive window, then as can be known according to the optical property of glass, its light path will be as shown in FIG., and the indoor refracted ray K ' of its directive is directive top ceiling direction, and be not high light about generally in the morning during 5:00-8:00 and at dusk during 16:30-19:00 this moment; As sunlight (M light among the figure, α " angle) with the time less than 45 ° of input angle directive windows, its light path as shown in FIG., its refracted light M ' will directive top ceiling direction, this moment is during about 8:00-during 16:00, be strong sunlight; L light among the figure, the sunlight of angle α ' are the index path of α ' when being 45 °, and L ' is a refracted light.In summary it can be seen, by this dioptric glass, can effectively a part of light be reflected outside window, and refraction is advanced indoor sunlight all with directive top ceiling direction, after the top ceiling reflection, shine indoor, thereby played the effect of soft light, stoped the direct projection of sunlight, overcome sunlight and shone directly into the infringement to human body such as desk or desk.Thereby can be widely used as the window-glass of office, family, school and other communal facilitys.

Claims

1, a kind of spination dioptric glass, one side is the plane, one side is the spination face, it is characterized in that the horizontal plane of toothed surfaces and the angle on its inclined-plane (θ) are 45 °, and its tooth deep distance (AB) equates apart from (AC) with opening, makes its wedge-formed incision constitute isosceles right triangle.
