Description

Pen suitable for use at night or dim place

The utility model belongs to a kind of writing pen that is made of as light source high brightness LED.

The effect of pen is to provide people to put down in writing, copy the instrument of various items, if there is not writing pen, many people, thing, thing will be forgotten thereupon, the preservation of culture, theoretical reckoning and various discovery all by the record of pen as preserving and the basis of development, therefore pen is that people work, indispensable a kind of instrument in the life.But, general night out of doors or in the dark the staff, as the person of checking meter of police, ticket seller, registration ammeter or gas table, hand flashlight lighting mostly and write, therefore brought inconvenience to work, occurred a kind of light emitting diode of making for material by gallium arsenic phosphide (GaAsP) or gallium phosphide (GaP) thus and be applied to placing of pencil lead.Often all seeing nib when using this pen to write, only can look at the luminous place of this light emitting diode again straight owing to the relation at visual angle, thereby the zone of writing forms anti-white effect, so can't know and see the literal of being write, in addition, used light emitting diode is that the gallium arsenic phosphide or the gallium phosphide material of low-light level made, its basic structure is a kind of concentric garden structure, must be fixed on the front end of pencil lead, just be enough to illuminate the near zone that writes, can't change if in a single day this light emitting diode just burns, can not reuse.

The purpose of this utility model is to propose a kind of light emitting diode by high brightness and places in the shaft of a writing brush as light source, the pen that is suitable for night or dark place use that also includes light conductor, interior pipe, pencil lead and conductive pieces and constitute, thus existing visual angle and anti-white problem in the prior art can be solved.

The technical scheme that the utility model adopted is that it is included in a front end is the cone and the shaft of a writing brush that a hole that can wear for pencil lead is arranged, high brightness LED that pipe in, light conductor, one are made by AlGaInP (AlGaInP) material and the electrical conduction member that constitutes by parts such as changeing cap, conducting strip, lead, spring.Wherein the shaft of a writing brush is to be made by conductive material, the center bore of its leading section cone is than the aperture greater than pencil lead, light conductor is the outside that supplies the tip plant of pencil lead and protrude from light conductor, light conductor places the cone inside of shaft of a writing brush front end, the front edge of this light conductor is showed out the hole of shaft of a writing brush front end, and forms a garden ring-type.Interior pipe places shaft of a writing brush inside, pencil lead to place interior pipe central authorities and passes the hole of shaft of a writing brush leading section cone, light emitting diode is placed the leading section of interior pipe, the positive pole of light emitting diode is clamped on the inwall of the shaft of a writing brush, its negative pole is connected in conducting strip through electric lead, and positive pole forms the loop through the shaft of a writing brush, commentaries on classics cap, spring, power supply and conducting strip with negative pole.

The utility model can make the scope of light source direct projection in single font size, can avoid the diverging light of front end and influences the visual angle of writing, and have the brightness height, and power saving and light emitting diode are changed characteristics such as easy, so it has practical value.

Fig. 2 is a profile of the present utility model.

Fig. 3 is an outside drawing of the present utility model.

Fig. 4 is user mode figure of the present utility model.

In conjunction with above-mentioned each accompanying drawing preferred embodiment of the present utility model is described now.The shaft of a writing brush that it is a cone by a leading section (10), it is made by conductive material, and its cone is provided with a hole that can supply pencil lead (40) to pass, and the diameter in this hole is than the diameter greater than the most advanced and sophisticated pencil of pencil lead (40).A light conductor (30) is for the plant of pencil lead (40) point and protrudes in light conductor (30) outside, group is inserted the light conductor (30) and the pencil lead (40) that form to enter from the back stomidium of the shaft of a writing brush (10), make light conductor (30) place in the cone of the shaft of a writing brush (10) front end and make the front edge of light conductor (30) show out the hole of this shaft of a writing brush (10) front end, and form a ring-type.Interior pipe (20) is inserted in the shaft of a writing brush (10) inside, and pencil lead (40) is interval in the shaft of a writing brush (10) inside, and the positive pole of light emitting diode (50) is clamped between the shaft of a writing brush (10) inside and interior pipe (20) outside and is connected on the inwall of the shaft of a writing brush (10), but its negative pole mat power lead (90) is connected on the conducting strip (70) of interior pipe (20) rear end, the contact-making surface rear portion of this conducting strip (70) spring (80) front end inner with changeing cap (60) can install two batteries that are connected in series (100), so, the positive pole of light emitting diode (50) can be by the shaft of a writing brush (10), spring (80), change cap (60) and produce electrical connection, and the negative pole of light emitting diode is connected with conducting strip (70) by power line (90), when changeing cap (60) when rotating forward, the negative pole that makes battery (100) contacts with conducting strip (70) and constitutes the loop, thereby light emitting diode (50) is luminous, otherwise then not luminous for open circuit.The utility model also can be provided with the conductive metal foil of applying on the tube wall of interior pipe (20), and is connected to this conducting strip (70), in order to replace power line (90).

The front end of light emitting diode (50) contacts with light conductor (30), and light source can be guided out from light conductor (30) leading edge and the shaft of a writing brush (10) formation annular gap.Light emitting diode (50) can adopt the light of jaundice light or green light to have easypro purpose effect.The utility model is because the high brightness LED and the employing daylighting degree that adopt the AlGaInP material to make lose the light conductor that little material is made, and therefore the intensity of light source of guiding out is applicable to that night or dark place record write illumination and use.
