Abstract

The utility model relates to an electric light pen, particularly an electric light pen which is especially suitable for writing under the condition of dim light and night without other light source. The shape of the utility model is similar to an ordinary ball-point pen or a fountain pen. An illuminative closed circuit which takes a micro cell as the electric source is established firstly. The micro cell is arranged on the tail end of the pen and connected with leading wires of a positive pole and a negative pole. A switch on the end of the pen is communicated with a miniature lamp (or a luminous diode) fixed on the pen head. When the switch is turned on, the lamp bulb can luster to illuminate writing objects directly. Then the purpose of writing under the condition of dim light and night without other light source is reached.

Description

Pen with illuminating device

The utility model belongs to a kind of electric light writing implement, particularly relates to one and is exclusively used in the light darkness and does not have the electric light light pen of writing under other light source situation night.

In the prior art, all kinds of writing implements are for many years wide-spread, and development does not appear at the light darkness as yet and do not have the instrument of writing under other light source situation night so far.

Traditional ball pen, fountain pen, slide core formula plastic tube pencil, writing brush etc. all do not have this function.In recent years, several advanced writing implements appearred on the market once, though these writing implements in various degree to attractive in appearanceization, convenient purification development, but still do not have dark and do not have the function that can write under other light source situation a night at light.Another kind of known " electrical measurement pen " is the specific purpose tool of electrical verification, and be more irrelevant with the utility model.

The purpose of this utility model is: break through traditional mode, proposes a kind ofly to be exclusively used in the light darkness and not have the electric light pen that can write under other light source situation night.

The purpose of this utility model realizes by following scheme: at first set up an illumination closed circuit.This illuminating line is done power supply with minicell, with its by be loaded on the pen tail end, picking out the positive and negative polarities lead-in wire then connects by tip of the brushstyle of a writing or painting switch and the pea lamp (or light emitting diode) that is fixed on the nib place, when closing a switch, bulb just sends light, direct irradiation is being write on the thing, has just reached the purpose that also can write under the situation of not having other light source night.Accompanying drawing and drawing are described as follows:

Fig. 1 is the circuit working schematic diagram of the utility model embodiment 1.

Fig. 2 is a machinery integral cutaway view of the present utility model.Engineer's scale: 2:1, the physical length of pen is 14 centimetres.

With reference to Fig. 1: e is a minicell among the figure, and K is a switch, and R is pea lamp (or light emitting diode), and when closing a switch, line conduction, pea lamp just send light, have satisfied the needs of writing night.The light source of bulb can be any color.

With reference to Fig. 2: (1) is penholder among the figure, pea lamp (or light emitting diode) (2), lead (3), (5), sheet metal (4), minicell (6), compression spring (7), fixed contact (8), bonding jumper (9), form closed lighting circuit, pea lamp on this closed circuit (or light emitting diode) and two leads all become one with penholder, penholder is made with transparent hard plastic or other transparent insulating substrate, not interrupted with the light that guarantees bulb, there is a gummed wire to be connected between sheet metal (4) and the lead (3), to guarantee that sheet metal can take out, the cap for brush (10) is made with duroplasts or other insulant, its type shape is a cylinder and a roundlet pipe assembly, be threaded with the penholder tail end, at the bottom of thread, wear a little bonding jumper along cap for brush diameter, the centre of bonding jumper contacts with the compression spring, and the two ends order is formed rotary switch with contact (8), when cap for brush edge turns clockwise, two engage contacts, circuit turn-on, when cap for brush edge is rotated counterclockwise, two contact separation, circuit is cut off, just reached switching purposes thus, the tail end of pen core (12) has a round pen pad (11), and purpose is in order to guarantee that each parts of pen core tail end keep poised state.

Claims

1, a kind of electric light pen, particularly be exclusively used in the light darkness and do not have the electric light pen of writing under other light source situation night, feature of the present utility model is: have an illumination closed circuit of doing power supply with one group of minicell, minicell is installed in the tail end of pen, anodal by sheet metal (4), lead (3) joins with a utmost point of the pea lamp (or light emitting diode) of nib, negative pole is by compression spring (7), bonding jumper (9), contact (8), lead (5) joins with another utmost point of pea lamp (or light emitting diode).

2,, it is characterized in that, between sheet metal (4) and the lead (3), be connected by a colloid flexible cord by the described electric light pen of claim 1.

3, by the described electric light pen of claim 1, it is characterized in that: the compression spring is installed between the negative pole and the cap for brush of battery, and contacts with bonding jumper (9).
