Abstract
The utility model provides an eye-protection lamp assisting a calligraphy practice. The eye-protection lamp comprises a module used for projecting a copy book for the calligraphy practice and an eye-protection lamp tube which is arranged on the module in a sleeved mode. According to the eye-protection lamp assisting the calligraphy practice, the module used for projecting the copy book for the calligraphy practice is additionally arranged on the basis of an existing eye-protection lamp, the copy book for the calligraphy practice is projected on a piece of practice paper through the module, and the eye-protection lamp assisting the calligraphy practice has no requirement for paper and is convenient to use.
Description
Technical field
The utility model relates to a kind of optical devices, is specifically related to a kind of eye-protecting lamp of auxiliary drills to improve one's handwriting.
Background technology
Calligraphy is China's tradition exercise project, can improve practitioner's body and mind quality.Recently the rise of China's national literature heat makes drills to improve one's handwriting again in China's prosperity.Recently, China is in order to keep traditional culture, and drills to improve one's handwriting are set to pupil's required course.The traditional calligraphy exercising method comprises learns to write by tracing over characters printed in red and imitative shadow.Learn to write by tracing over characters printed in red and need write in the red cutline font exercise of special printing, imitative shadow is thin paper to be placed on the copybook imitate, and learning to write by tracing over characters printed in red needs special paper, and imitative shadow then needs thin especially paper, and is all not too convenient in exercise.
The utility model content
The purpose of this utility model is to provide a kind of eye-protecting lamp of auxiliary drills to improve one's handwriting.
For achieving the above object, the utility model has adopted following technical scheme:
This eye-protecting lamp comprises for the module of projection copybook and the eye-protecting lamp fluorescent tube that is sheathed on the ring-type on the described module.
Described module is digital projector or film projection assembly.
Described film projection assembly comprises light source and the light-collecting lens, copybook film and the projection magnifier that set gradually along the light path of light source.
Described eye-protecting lamp also comprises power supply, and described module and eye-protecting lamp fluorescent tube are parallel between the two ends of power supply.
Described eye-protecting lamp also comprises adjustable for height support and base, and an end of support links to each other with described module, and the other end links to each other with base, and base is provided with power switch and projection eye-protecting lamp change-over switch.
The beneficial effects of the utility model are embodied in:
The utility model increases the module that is used for the projection copybook at existing eye-protecting lamp, utilizes this module that copybook is projected on the exercise paper, and paper is not required, and is easy to use.
Further, if adopt digital projector and in conjunction with electronic copybook, then can dynamically represent the detailed process of learning calligraphy, as gesticulate, order of strokes observed in calligraphy exercise, not only use more conveniently, and practice effect also is further enhanced.
Description of drawings
Fig. 1 is structural representation of the present utility model (realization of film projection copybook);
Fig. 2 is that power supply control of the present utility model and function are switched synoptic diagram;
Among the figure: 1 is light source, and 2 is light-collecting lens, and 3 is the copybook film, and 4 are the projection magnifier, and 5 is the eye-protecting lamp fluorescent tube, and 6 is support, and 7 is power switch, and 8 is the copybook projection, and 9 are projection eye-protecting lamp change-over switch, and 10 is power supply, and 11 for being used for the module of projection copybook.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 1 and Fig. 2, eye-protecting lamp described in the utility model comprises for the module 11 of projection copybook and the eye-protecting lamp fluorescent tube 5 that is sheathed on the ring-type on the described module, described module is digital projector or film projection assembly, described film projection assembly comprises light source 1 and the light-collecting lens 2 that sets gradually along the light path of light source 1, copybook film 3 and projection magnifier 4, described eye-protecting lamp also comprises power supply 10, described module and eye-protecting lamp fluorescent tube 5 are parallel between the two ends of power supply 10, described eye-protecting lamp also comprises adjustable for height support 6 and base, one end of support 6 links to each other with described module, the other end links to each other with base, and base is provided with power switch 7 and projection eye-protecting lamp change-over switch 9.
Principle of work of the present utility model is:
After connecting power switch, utilize the projection eye-protecting lamp change-over switch will be for module and the power connection of projection copybook, font pattern behind the light source luminescent on the copybook film projects to be used to the paper that practices calligraphy, copy use for the practitioner, rotate projection eye-protecting lamp change-over switch, then light source is closed, and eye-protecting lamp fluorescent tube and power connection use for the study illumination.
Embodiment
The calligraphy projecting optical device has two kinds of implementations, and the one, adopt traditional film projection, the 2nd, adopt the electronic projection technology.
The course of work is: produce light behind optical concentration mirror optically focused by the LED cold light source, irradiation copybook film then amplifies through the optical loupes head, projects to and waits to write on the paper.If do not adopt film projection, and adopt the electronic projection technology, then can adopt electronic projection chips such as DLP or LCos, adopt cold light source equally, and need microcomputer system to assist, store and realize the electronic copybook function.Other forms with scheme one similar, just will be replaced by little display projection system by the optical devices that light source, condenser, copybook film, enlarging lens are formed, and increase control and use microcontroller in order to store font, the projection of realization font.This scheme cost is higher, but can realize dynamic electronic copybook, can observe the order of strokes observed in calligraphy and write order, has lively characteristics directly perceived, and has avoided the process of manual transpose card film.
Because the angle of inclination exists, projection film and projected image all need to carry out deformation design in advance.Change the optical loupes head and can obtain bigger enlargement factor.
This device is ibidemed the science of law with optical technology, modern electronic technology and is practised combination, makes learning calligraphy be more prone to interesting, simultaneously with this function and eye-protecting lamp or desk lamp combination, makes this device also can be used as general eye-protecting lamp and uses.
Principle of work of the present utility model is similar to traditional photographic enlarger, but innovates with regard to following place:
(1) for fear of the people's that writes head and blocking of hand, adopted the oblique-angle projection technology of left front, about 15 degree (being that projecting direction is not orthogonal to desktop).
(2) the oblique-angle projection mode has caused the distortion of projected image on paper, designs the projection copybook accordingly, makes it through projection, forms the font of standard at paper.
(3) projection section can adopt traditional film projection technology, also can adopt the micro projection chip, and the latter can store a large amount of copybooks, and can dynamic demonstration order of strokes observed in calligraphy writing process, realizes dynamically facing the effect of subsides.
(4) the utility model can be regulated height within the specific limits, makes that the copybook projected size is adjustable, adapts to the demand of different big small fonts.
