Abstract

The utility model relates to a luminous pen with light-emitting diodes (LED), which comprises a pen cap, a pen holder, a pen tube and a pen core. The lower portion of the pen holder is provided with a battery assembly and a switch. The luminous pen with the LED is characterized in that the LEDs are arranged on two sides of the front end of the pen tube or in triangle mode, and the LEDs are integrated with the pen tube. Therefore, luminous efficiency is greatly improved, a clear lighting source with moderate light intensity is formed around a pen point, no shade is formed, and work and life of users is facilitated.

Description

A kind of luminous pen of LED that has

Technical field

The utility model relates to cultural tools, particularly a kind of pen that has led light source can be luminous.

Background technology

People are in work and life; usually can run into the situation of environment than dark or insufficient light; particularly in some special industries; as field work, the down-hole of no illumination condition, underwater operation; work at night and power failure etc. occurs; in the time of need writing or write down with pen, can be dark very inconvenient because of light, even dally over one's work and cause damage.Existing light pen is to have adopted the lighting circuit that is composed in series successively by lamp pearl, battery, metal spring leaf and switch a bit, some has set up lighting device on one side or on the cap for brush at penholder, because all there is the bigger problem of volume in these modes, can not be directly arranged in the nib place, it is convenient inadequately to use, light-emitting component all is arranged on penholder one side mostly, can produce shade in writing, and illuminating effect is undesirable.Current, comprise that the led light source of light emitting diode is little, in light weight with its volume, light even, the advantage of economize on electricity environmental protection is widely used, constantly enter in every way in people's the life.

Summary of the invention

The purpose of this utility model is the needs of writing under specific conditions such as light dark for satisfying, and proposes a kind of luminous pen of LED that has.

The technical solution adopted in the utility model is: a kind of luminous pen of LED that has, comprise the cap for brush, penholder, the shaft of a writing brush and pen core, in the bottom of penholder battery component and switch are housed, it is characterized in that in shaft of a writing brush front end both sides or be triangularly arranged being provided with the LED light emitting diode.

Described LED light emitting diode adopts envelope to mould mode and the shaft of a writing brush is made one.

Described switch is by being located at the control knob control of penholder tail end.

The beneficial effects of the utility model are: by the shaft of a writing brush front end at the nib rear portion LED light emitting diode is set, its luminous efficiency is improved greatly, form moderate, the lighting source clearly of brightness in the use around the nib, shadow-free provides convenience for people's work and life; Overall volume is little, simple in structure, easy to carry, and is of many uses, in people go out work and tourism, both can be used as pen and has been used to write, and dark at night unglazed place also can be used as miniature torch and uses.

Description of drawings

Fig. 1 is the structural representation of one of the utility model embodiment;

Number in the figure is represented respectively: the 1-cap for brush, 2-nib, 3-LED light emitting diode, the 4-shaft of a writing brush, 5-battery component, 6-switch, 7-control knob, 8-penholder.

The specific embodiment

As shown in Figure 1 and Figure 2, have the luminous pen of LED and comprise the cap for brush 1, penholder 8, the shaft of a writing brush 4 and pen core, pen core is contained in the shaft of a writing brush 4, battery component 5 and switch 6 are housed in the bottom of penholder 8, be provided with LED light emitting diode 3 in the shaft of a writing brush 4 front end both sides, also can adopt three light emitting diodes, be symmetrical arranged by rounded projections arranged, 360 ° form uniform source of light around nib.LED light emitting diode 3 adopts envelope to mould mode and the shaft of a writing brush 4 is made one.Its battery component 5 comprises the button cell of at least two joint series connection, power supply is connected with LED light emitting diode 3 by the interior plain conductor of establishing electric wire or being preset in the shaft of a writing brush 4 assemblies, LED light emitting diode 3 can be selected small-sized white light LED or high-brightness white-light LED for use, improves luminosity and makes light more even.

Control knob 7 controls of switch 6 by being located at penholder 8 tail ends, control mode can be the knob mode, also can adopt the button mode.
