Abstract

The utility model discloses a shadowless luminous pen, and aims at providing the shadowless luminous pen with a light source positioned at the head part of a pen holder. The shadowless luminous pen comprises a pen holder (1), a pen cap (2) and a pen core (3), wherein an annular light source (4), a lead (5), a switch (6) and a battery jar (7) are arranged on the pen holder (1), and the annular light source (4) is arranged at the head part of the pen holder (1). The shadowless luminous pen has the advantages that: 1, a light emitting diode (LED) is adopted for luminescence, and the shadowless illumination effect can be reached; 2, the shadowless luminous pen can be used as a flashlight, and the practicability is high; and 3, the structure is simple, and the manufacture cost is low.

Description

No shadow light pen

Technical field

The utility model relates to a kind of pen, and in particular, it relates to a kind of light pen that does not have shadow.

Background technology

The pen of present use does not have the illumination function mostly, and perhaps light source all is positioned at the penholder afterbody, makes illumination not reach good effect, and the influence of easy formation shadow is write.Up to the present, the no shadow light pen that a kind of light source is positioned at the penholder head does not appear on the market as yet.

Summary of the invention

The purpose of the utility model is that to be difficult to solve illuminating effect bad to existing light pen, be prone to form the problem of shadow, and a kind of light source that provides is positioned at the no shadow light pen of penholder head.

The no shadow light pen of the utility model; Comprise penholder, the cap for brush and pen core, described penholder is provided with annular light source, lead, switch and battery case, and described annular light source is positioned at the penholder head;, be embedded in an annular transparent plastic and form around series connection by four miniature LED.Described lead is positioned at the penholder inwall, is processed by narrow sheet metal, and described switch is positioned near penholder afterbody place, and described battery case is positioned at the penholder afterbody, and the described cap for brush and pen core are the common cap for brush and pen core.

The beneficial effect of the utility model is: (1) is furnished with the LED light-emitting device around being looped around nib top, and the illumination that LED sends can be write it in the dark, and can be reached no shadow effect to paper; (2) pen can be used as simple and easy flashlight use, and is practical; (3) simple in structure, cheap.

Description of drawings

Fig. 1 is the structural representation of the utility model; Fig. 2 is the annular light source vertical view of the utility model; Fig. 3 is that the circuit of the utility model connects sketch map;

Among the figure: penholder 1, the cap for brush 2, pen core 3, annular light source 4, lead 5, switch 6, battery case 7.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further to describe.

In Fig. 1, no shadow light pen is made up of penholder 1, annular light source 4, lead 5, switch 6, battery case 7, the cap for brush 2 and pen core 3 etc., and described annular light source is made up of 4 miniature LED and transparent plastic ring; Lead 5 is narrow sheet metal; Be close to the penholder inwall, described switch 6 can promote up and down, and described battery case 7 can be put 3 miniature button cells; Battery case 7 is separable with penholder 1, and both are by being threaded.

In Fig. 2, four miniature LED are formed in parallel, and are embedded in the transparent plastic ring.

In Fig. 3, annular light source 4, switch 6, battery all are in series.

During use, only need switch is upwards pushed away, can connect circuit, switch is pushed away disconnecting circuit downwards.
