Description

A kind of pen cap with illumination functions

Technical field

The utility model relates to a kind of pen cap with illumination functions.

Background technology

People need to write in the dark sometimes, during as operation in the wild or tourism, camp and there is no the place of lamp in the wild, that writes some words will be very difficult, put barn lantern, the battery powered LED of the employing had now in the past, although present LED can maintain and light for a long time, but the reading lamp that LED is not necessarily special sometimes, but a kind of camp lamp are also conveniently to write so in the wild.In addition, often running into the situation that light is strong not, is exactly certain light, but owing to taking pen and radiation direction may blocking by human body or head or hand, drop on the local light write inadequate, someone develops Writing pen suitable for use at night at present, utilizes light emitting diode to light, but limits due to the cost of pen, all can not buy Writing pen suitable for use at night, and child uses pencil, the setting of lamp cannot be carried out, therefore need there is Writing pen suitable for use at night to improve thoroughly existing.

Summary of the invention

The purpose of this utility model solves Writing pen suitable for use at night in prior art only self, cannot be used for the problem existing for pencil, provide a kind of pen cap with illumination functions.A kind of pen cap with illumination functions of the utility model design, comprises the pen cap, it is characterized in that: be provided with battery and lampet and switch at the rear portion of the pen cap, and lampet connects battery by wire and switch, and lampet is connected the guide-lighting ring being positioned at pen cap front end by light-guiding pillar.Guide-lighting ring one lucite system becomes, and the side of its ring is coated with one deck reflector layer.Lampet is light emitting diode.The utility model has the advantages that can be used for various pen in night or compared with writing under dark situation, be the best authoring tool in campsite not by the restriction of place time, can illumination be provided simultaneously.

Accompanying drawing explanation

Accompanying drawing is section of structure of the present utility model.

Detailed description of the invention

A kind of pen cap with illumination functions in figure, comprises the pen cap 1, it is characterized in that: be provided with battery 2 and lampet 3 and switch 4 at the rear portion of the pen cap, and lampet connects battery by wire and switch, and lampet is connected the guide-lighting ring 6 being positioned at pen cap front end by light-guiding pillar 5.Guide-lighting ring one lucite system becomes, and the side of its ring is coated with one deck reflector layer 7.Lampet is light emitting diode.

During use, when needing to write in night darkness place or darker environment, can the pen cap be enclosed within pen, then switch is opened, light lampet, then light is directed to the guide-lighting ring of pen cap front end by light-guiding pillar, because guide-lighting ring is that lucite system becomes, the side of its ring is coated with one deck reflector layer, therefore light casts out from the anchor ring on guide-lighting ring top, around the nib on just in time illuminating pen top, meet light when writing, in order to save battery, can be lampet with light emitting diode, the volume of light emitting diode is little, brightness is large, and it is reliable, power consumption is also little, general button cell just can meet illuminating of long period.

The size dimension of the pen cap, can design according to pen used, by the design of pen cap internal diameter greatly a bit, may be used for different pens, jump ring can be set in pen cap internal diameter, ensure the pen being suitable for different thicknesses, the length of certain pen cap is also wanted suitably, ensures to be inserted in the pen cap by the rear portion of whole pen, only flows a nib part again outside the pen cap, guarantee is be held in pen cap front portion after holding, and the light that can not block the pen cap sends.

Head institute of the present utility model isolychn range of exposures is comparatively large, except writing, also may be used for a small amount of reading.
