Description
Technical field
The present invention relates to a kind of lettering pen with lighting device, 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.At present, having occurred many on the market is the LED light pen of lighting source with the white light LEDs, 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 these patents, and be difficult to adopt the dry cell of various models on the market, common column type battery such as rechargeable battery is as power supply, and 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.
At this problem, I have patent of invention in first to file, and application number is " a kind of LED light pen " of 200510107778.3 (publication number is CN1785691A), discloses a solution.This LED light pen be between battery and light emitting diode by one in the dress booster circuit boost module be electrically connected, pen core then runs through and mistake from the central authorities of this boost module, wherein battery is a column type battery.This patent application is owing to adopted boost module, therefore only can make white light LEDs luminous with common column type battery once joint 1.5V, and the bottom that light emitting diode is arranged on penholder makes the illumination position concentrate on around the nib, and pen core runs through and design excessively from the central authorities of boost module, makes that then the use of long pen core in the LED light pen becomes possibility; But, also Just because of this, just can't adopt the more thick pen core of same storage China ink, and because boost module is arranged on the position near the penholder head, the manufacturing and the assembling of penholder all brought extra requirement.
On the other hand, the LED illuminator is except the most basic lighting source of conduct, some can be used as SOS distress signal lamp because of having flashing function, some can be used as the currency examine lamp because of having cash examining function, some band laser is then as laser indicator lamp, in some special occasions and unexpected environment, except needs illuminations, also need this LED with specific function luminous.And existing LED light pen all has only a luminous loop, be that light emitting diode can only be arranged on the place in the penholder, can not be provided with many places, be that existing technology is difficult to make two light emitting diodes that are separately positioned in the penholder two ends up and down simultaneously luminous, therefore, common LED light pen, its LED is only as lighting source, himself do not possess second LED illuminator, special light source can't be provided again, thereby be unsuitable for practical application.
Summary of the invention
