Description
Technical field
The utility model belongs to technical field of lighting fixtures more particularly to a kind of adjustable optical reading plate of eyeshield LED.
Background technique
With the development of the times with science and technology progress, electronic equipment it is universal make people with eye be accustomed to it is more and more worse,
Along with the learning tasks burdensome of student, eyes cause damage, visual impairment.With the development of science and technology, going out on the market
Existing some reading plates, are placed on books surface illumination.General to read what plate was made of plate body and illumination region, plate body is as light
The disseminule of line is similar to guiding fiber, and only when the side wall of cylinder receives damage, light can just propagate from guiding fiber.And it is existing
Plate body surface be it is smooth, the light source of plate body surrounding side account for propagate light source 80 or so percent, really act as in this way
It is lower with the light utilization illuminated to books.
Chinese patent Authorization Notice No. CN204729945U, authorized announcement date on October 28th, 2015, it is entitled " a kind of just
Take formula and read plate " to disclose a kind of by plate body material be PVC, easy to carry, which is disadvantageous in that: the table of plate body
Face be it is smooth, the distribution of the light source of plate body surrounding side is lower, and the light on plate body surface is less, light utilization rate is lower.
Utility model content
The purpose of this utility model is that solve the above-mentioned problems and simple, the design reasonable one that provides a kind of structure
The kind adjustable optical reading plate of eyeshield LED, increases the light for being distributed in plate body surface, and can be used as flashlight use.
The utility model achieves the above object through the following technical schemes:
A kind of adjustable optical reading plate of eyeshield LED, it includes illumination region and plate body, and illumination region includes shell, the side of shell
It is provided with notch, is equipped with LED patch in notch, plate body is located in notch, and LED patch is connected with battery by control switch, described
Several grooves are provided on plate body；Groove allows light to be distributed in the side of groove on plate body, to increase plate body surface
The light of distribution, principle is damaged similar to the outer wall of optical fiber, and light is propagated from breakage；The shell is equipped with diode, and battery
For diode power supply, it is in series with switch between the battery and diode, the function of illumination may be implemented by LED lighting,
The reading plate can be used as flashlight lighting use.
As the technical solution that the utility model advanced optimizes, for the ease of the carrying of this reading plate, the plate body is
PVC soft glass is made, and without using in the case where the reading plate, can reduce transport space by rolling up on the shell plate body.
As the technical solution that the utility model advanced optimizes, the battery is rechargeable lithium batteries.
As the technical solution that the utility model advanced optimizes, USB interface is additionally provided on the shell, the battery is
USB interface power supply, may be implemented supplying power for outside by USB interface, is inserted directly into the small fan etc. of USB interface.
As the technical solution that the utility model advanced optimizes, an electricity is in series between the LED patch and battery
Position device, potentiometer is slide rheostat, passes through the brightness of the adjustable LED patch of slide rheostat.
As the technical solution that the utility model advanced optimizes, the groove is circle, and the depth of groove is from centre
It gradually deepens around, and then makes have reeded plate body part formation convex lens, the scattering according to convex lens to light is similar to put
Big mirror makes the word under plate body become larger, and reads convenient for user.
The utility model has the beneficial effects that:
1) the utility model allows light to be distributed in the side of groove by the groove on plate body, to increase plate body
The light of surface distribution, and then the distribution of the light of plate body side is reduced, increase the utilization rate of light；
2) function of illumination may be implemented by LED lighting for the utility model, which can be used as flashlight photograph
Bright use；
3) the utility model structure is simple, and stability is high, and design rationally, is easy to implement.
