Description

A kind of LED light pen

Technical field

The utility model relates to a kind of lettering pen with lighting device, and relating to a kind of specifically is the LED light pen of lighting source with LED (light emitting diode).

Background technology

People need writing words in the dark sometimes, though the paper pen is arranged in the hand, but can not make one's wish fulfilled, so, the light pen that has lighting source arises at the historic moment, because this light pen can also doublely be made miniature flashlight, help in the dark to seek article, see other purposes such as wrist-watch or reading letter, therefore be subjected to people's favor.What initial light pen adopted is common bulb, but along with the fast development of white light LEDs in recent years, the LED light pen that with the white light LEDs is lighting source continues to bring out, in Chinese utility model patent, the patent No. is that 02200769.5 (notification number is CN2520256Y) " knock-type special soft cover lamp pen " and the patent No. are that " light pen of the stretching pen cap " of 03253042.0 (notification number is CN2645929Y) all discloses this light pen, but because the luminous voltage of white light LEDs needs more than the 3.6V, add that bulk is limited in the penholder, therefore, disclosed technical scheme all is to adopt the button cell of at least three series connection as power supply in above-mentioned three patents, because the capacitance of button cell is limited, price is high and universal inadequately, thereby just very inconvenient aspect battery altering; On the contrary, common column type batteries such as the dry cell of various models, rechargeable battery are then very universal in the market, can buy with being in big small shop, supermarket, and price is low, capacity is high, but because the diameter and the length of penholder are all limited, can't be with the column type batteries of three joint series connection as power supply, therefore how become the technical problem that the sector is badly in need of solution as the power supply of LED light pen with column type battery.On the other hand, in above-mentioned two patents, battery, light emitting diode and pen core are separately positioned on rear portion, middle part and the front portion of penholder, its shortcoming has two: one, and what light emitting diode illuminated is the middle part and the peripheral position thereof of penholder, rather than concentrate on nib around, so its decoration functions will be more than utility function; The 2nd, pen core needs often to change because the position is limit, and its length printing ink short, that held is few, is easy to use up, thereby also practical inadequately.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of LED light pen that adopts common column type battery as power supply at above-mentioned prior art present situation.

Another technical problem to be solved in the utility model provides a kind of position of throwing light on and concentrates on nib LED light pen on every side.

Another technical problem to be solved in the utility model provides a kind of LED light pen that adopts long size pen core.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this LED light pen includes penholder and is arranged on penholder interior pen core, battery and at least one light emitting diode, wherein battery then is positioned at the top of penholder, it is characterized in that described battery is a column type battery, described light emitting diode is arranged on the bottom of penholder, and between battery and light emitting diode by one in the boost module of dress booster circuit conduct electricity connection mutually, described pen core then runs through and mistake from the central authorities of this boost module.

Described boost module can be a frame-type, promptly include upper surface, lower surface and at least one support that connects upper and lower end face of having centre bore respectively, wherein booster circuit promptly is positioned on the support, and described pen core promptly runs through and mistake from the centre bore of upper and lower end face; Described boost module also can be closed, is the column with a centre bore, and wherein booster circuit is within it packed, and described pen core promptly runs through and mistake from this centre bore.
