Abstract

The utility model relates to a pair of head-type amplifying glasses for watching TV, which is composed of a cap with a visor, a glasses frame and eyeglasses, wherein, the eyeglasses are convex prisms, the visor is movably connected with the glasses frame, the numeric area of the convex edge angles of the eyeglasses is from one DEG to ten DEG, and the numeric area of the radii of the circular arcs of the convex surfaces is from 30 to 50 cm. The utility model has the characteristics of simple structure, convenient wearing, easy production and low cost with affecting others to watch TV, and makes people watch large-sized stereoscopic TV programs at comfortable home so as to truly achieve the goal of a home cinema.

Description

Wear-type TV magnifying spectacles

The utility model relates to magnifying spectacles, relates in particular to a kind of wear-type TV magnifying spectacles.

Television image amplifier in the past adopts convex lens to amplify more, promptly places convex lens more much bigger than TV screen between TV screen and eyes, utilizes lens to be close to one-tenth reason principle in the focal length one and obtains an amplification and put television image far away (virtual image).The convex lens area that this amplification method needs is very big, not only be difficult for processing, and involve great expense, use extremely inconvenient, and the number of watching is very limited, because only watch the people of TV just can obtain normal enlarged image in the center, what the bystander saw is the trapezoidal image of distortion.

That the purpose of this utility model is to provide is a kind of simple in structure, cheap, have relief wear-type TV magnifying spectacles.

The technical solution of the utility model is: by movable connection method one magnifying spectacles is set on the bongrace of capful, two eyeglasses are convex prism.

The fin angle angle span of convex prism of the present utility model is 1 degree～10 degree, and best value is 6 degree～8 degree; Its convex surface arc radius span is 30～150 centimetres, and optimum value is 70 centimetres.

The utility model is when seeing big screen film at the cinema, two principles with great visual angle that constitute to eyes to formed mitre between the screen and big screen, utilize the light refraction rule of two convex prisms, increase two angle and visual angles artificially to television screen, formation is as the sensation of watching film at the cinema, to realize amplifying purpose; Also have strong stereoscopic sensation simultaneously, especially watch the image (as distant view scenery with hills and waters, sky, ocean, forest, open country etc.) of distant view.The utlity model has simple in structure, wear conveniently, make easy, cheap, do not influence the characteristics that other people watch TV, in comfortable family, just can see the large stereo TV programme, really realize the purpose of home theater.

Fig. 1: be the utility model structural representation.

Fig. 2: be imaging schematic diagram of the present utility model.

Below in conjunction with accompanying drawing the utility model is further elaborated.

The utility model comprises that cap 1, picture frame 2 and eyeglass 3, two eyeglasses 3 are convex prism, and its corner angle value is 6 degree, the convex surface arc radius is 70 centimetres, bongrace 4 tops are provided with web member 5, and picture frame 2 positive middle parts are provided with corresponding web member 6, and web member 5 can be realized flexibly connecting with web member 6.

Amplification principle of the present utility model as shown in Figure 2.The light of CD image has produced refraction behind left convex prism, changed original incident direction, and the image xy that left eye A is seen has been offset some distances left than real image CD.In like manner the CD image light has also produced refraction behind right convex prism, changed original incident direction, the image SH that right eye B is seen also has been offset some distances to the right than actual figure CD, because two convex prism parameter unanimities, so two soon to image just become two pairs have been offset certain distance a little than actual image equal-sized image, if the skew of this two sub-picture apart from the distance of summation less than two eyeballs, the FE point imaging that crosses a long way off of the visual angle extended line of this two sub-picture, because the amalgamation of two eyes, what be presented in ours at the moment promptly is that image far away is put in the amplification that a pair is extended to the TV the inside.Because television image extends inwards,, and has stereoscopic sensation so not only image is big when wearing these glasses and seeing TV.

Claims
