Description

A kind of LED is without shadow pen

Technical field

The present invention relates to the LED write on a kind of tool more particularly to a kind of paper without shadow pen.

Background technique

Pen is the common necessity of office worker.Conventional pen when in use, it is enough bright to need to guarantee that use environment has Degree.Under environment or special low-light level environment of the night without illumination, such as bar, dark staircase etc., user because It is very inconvenient to be invisible so can only write while with flashlight.

The research and development of Vehicles Collected from Market writing implement are only dedicated to reinforcing for comfortable writing sense, fluent writing degree etc. Research, and most people is ignored for the demand of vision.The writing under low-light level environment how is coped with, allows the eyes of user The writing under adverse circumstances can be more cosily coped with, is merited attention.

In addition, the different influences for writing condition of light source position are huge under different illumination conditions, how hand is avoided The shade and a urgent need to solve the problem of light source irradiation and generation are blocked when holding pen.

Summary of the invention

The technical problem to be solved by the present invention is to how cope with the writing under low-light level environment, at the same avoid hand hold pen when The shade for blocking light source irradiation and generating, allows the eyes of user that can more cosily cope with the writing under adverse circumstances.

In order to solve the above-mentioned technical problem, the technical solution of the present invention is to provide a kind of LED without shadow pen, it is characterised in that: Including a shell, shell inner tail end is equipped with supplying cell, and head end is equipped with LED illuminator inside shell, and LED illuminator, power supply are opened It closes and one closed loop circuit is connected by wire jumper with supplying cell；

Shell head end and shell head are detachably connected, and pen core is set in a shell, and pen core head passes through a shell head；Shell Head is made of clear material；Holding area is set on the outside of LED illuminator installation place on shell.

Preferably, described shell inner tail end is equipped with battery holder, and the supplying cell is set on battery holder.

It is highly preferred that the battery holder is equipped with battery case, the supplying cell is set in battery case.

Preferably, described shell tail portion, which is equipped with, is easy to open the end cap for replacing the supplying cell.

Preferably, aperture at corresponding power switch on described shell, the control terminal of power switch pass through the hole and are exposed to a shell It is external.

Preferably, described shell head end lower edge forms external thread structure, forms internal thread structure, shell head in shell head End lower edge is connect with shell head by helicitic texture.

It preferably, further include pen cap match with shell structure, for protecting pen core injury-free.

It is highly preferred that the pen cap side is equipped with for the pen clip fixed with external structure.

Compared with prior art, LED provided by the invention has the following beneficial effects: without shadow pen

1, by having mounted LED lamp on head in pen, good writing environment can be provided under low-light level environment, be eyes There is provided it is comfortable write condition, the visual fatigue due to caused by insufficient light is effectively relieved, for for a long time under low-light level environment There is extraordinary effect for the people of work.

2, when hand holds pen, LED light light is not influenced, does not generate shade, comfortable writing degree is further improved, reduces Eye strain, it is inhibited to the shade as caused by light source.

3, the headlamp that can be used as in the short time uses.

Detailed description of the invention

Fig. 1 is LED provided in this embodiment without shadow structural schematic diagram.

Specific embodiment

Present invention will be further explained below with reference to specific examples.

Fig. 1 is LED provided in this embodiment without shadow structural schematic diagram, and the LED is made of without shadow pen such as lower component:

Supplying cell 1, the corresponding button cell of optional setting are continued a journey, and provide electricity for illuminator.

Shell 2, is made, diameter 2.2cm or more, thickness 0.5cm or more, long 20cm or so by market common materials.

The luminous lamp bead of LED patch, LED or other luminescent materials can be selected in LED illuminator 3.

Shell head 4, this part use transparent material, penetrate visible light and illuminate.

Wire jumper 5 is market common materials, for powering for LED illuminator.

Pen core 6 is the common pen core in market.

Power switch 7, for controlling the opening and closing of LED illuminator 3.

Pen cap 8, for protecting pen core injury-free.

Pen clip 9 is market common materials, for fixing pen tool.

2 inner tail end of shell is equipped with battery holder, and battery holder is equipped with battery case, electricity of the supplying cell 1 on battery holder In the slot of pond, equipped with the end cap to match with 2 structure of shell on the outside of supplying cell 1.Open end cap, i.e., conveniently replaced supplying cell 1。

2 inside head end of shell is equipped with LED illuminator 3.LED illuminator 3, power switch 7 and supplying cell 1 pass through wire jumper 5 Connect into a closed loop power supply circuit.Aperture at corresponding power switch 7 on shell 2, the control terminal of power switch 7 pass through the hole and are exposed to Outside shell 2, convenient for users to controlling the opening and closing of LED illuminator 3 by the control terminal of the power switch 7.

2 head end lower edge of shell forms external thread structure, forms internal thread structure, 2 head end lower edge of shell in shell head 4 It is connect with a shell head 4 by helicitic texture.For pen core 6 in shell 2, the tail portion of pen core 6 resists battery holder, the head of pen core 6 Across a shell head 4.

Shell head is made of transparent material, and the visible light for enabling LED illuminator 3 to issue, which penetrates, to be illuminated.It is held on shell 2 It holds position to be set on the outside of 3 installation place of LED illuminator, when such hand holds pen, does not influence LED light light and penetrate a shell head 4, no Generate shade.

Pen cap 8 matches with 2 structure of shell, for protecting pen core injury-free.The design of 8 side of pen cap has pen clip 9, is used for LED is fixed without shadow pen with external structure.

After power switch 7 is opened, connection supplying cell 1 and LED illuminator 3, light shine book by a transparent shell head 4 Carrier surface is write, good writing environment is provided.

This product when not used, covers pen cap 8, reduces the damage of pen core 6.

It when pen core is replaced, can be replaced by unloading low pen shell head 4 and the connection of shell 2, compatible pens all types of on the market Core.

The above, only presently preferred embodiments of the present invention, not to the present invention in any form with substantial limitation, It should be pointed out that under the premise of not departing from the method for the present invention, can also be made for those skilled in the art Several improvement and supplement, these are improved and supplement also should be regarded as protection scope of the present invention.All those skilled in the art, Without departing from the spirit and scope of the present invention, when made using disclosed above technology contents it is a little more Dynamic, modification and the equivalent variations developed, are equivalent embodiment of the invention；Meanwhile all substantial technologicals pair according to the present invention The variation, modification and evolution of any equivalent variations made by above-described embodiment, still fall within the range of technical solution of the present invention It is interior.
