一种 LED发光笔 LED light pen

技术领域 Technical field

本发明涉及一种带照明装置的书写笔，具体的说是涉及到一种以 LED (发光二极管)为照明光源的 LED发光笔。背景技术 The present invention relates to a writing pen with a lighting device, and more particularly to an LED lighting pen with an LED (Light Emitting Diode) as an illumination source. Background technique

人们有时会需要在暗处书写文字，手中虽有纸笔，却不能如愿以偿，于是，带有照明光源的发光笔应运而生，由于这种发光笔还可以兼做微型手电筒，帮助在暗处寻找物品、看手表或阅读书信等其它用途，因此受到人们的青睐。最初的发光笔采用的是普通灯泡，但随着近几年来白光 LED的迅猛发展，以白光 LED为照明光源的 LED发光笔不断涌现，如中国实用新型专利中，专利号为 ZL02200769.5(公告号为 CN2520256Y)的《揿动式特软套灯笔》和专利号为 ZL03253042.0 (公告号为 CN2645929Y)的《拉伸笔套的发光笔》都公开有这种发光笔，但由于白光 LED的发光电压需要 3.6V以上，加上笔杆内空间尺寸有限，因此，上述三个专利中所公开的技术方案都是采用至少三颗串联的纽扣电池作为电源，由于纽扣电池的电容量有限，价格高且不够普及，因而在电池更换方面就十分不便；相反，目前市场上各种型号的干电池、充电电池等普通柱式电池则十分普及，可随处在在大小商店、超市中买到，而且价格低、容量高，但是由于笔杆的直径和长度都有限，无法用三节串联的柱式电池作为电源，因此如何用柱式电池作为 LED发光笔的电源成为该行业急需解决的一个技术问题。另一方面，在上述两个专利中，电池、发光二极管和笔芯被分别设置在笔杆的后部、中部和前部，其缺点有二：一是发光二极管照亮的是笔杆的中部及其周边部位，而不是集中在笔尖的周围，因此其装饰功能要多于实用功能；二是笔芯由于位置所限，其长度短、所容纳的油墨少，很容易用尽，需要经常更换，因而也不够实用。发明内容 People sometimes need to write words in the dark, but they have paper and pen in their hands, but they can't get what they want. Therefore, a light-emitting pen with an illumination source comes into being. Because this light pen can also be used as a miniature flashlight to help find it in the dark. Other uses, such as items, watches, or reading letters, are therefore favored by people. The original illuminating pen used ordinary light bulbs, but with the rapid development of white LEDs in recent years, LED illuminating pens with white LEDs as illumination sources continue to emerge. For example, in Chinese utility model patents, the patent number is ZL02200769.5 (announcement) No. CN2520256Y) "Pulse-type special soft-sleeve lamp pen" and patent number ZL03253042.0 (publication number CN2645929Y) "Hybrid pen with stretch pen holder" are all disclosed with this kind of illuminating pen, but due to white LED The illuminating voltage needs to be 3.6V or more, and the space inside the pen holder is limited. Therefore, the technical solutions disclosed in the above three patents all use at least three series of button batteries as power sources, because the capacity of the button battery is limited, and the price is high. It is not popular enough, so it is very inconvenient in battery replacement. On the contrary, various types of dry batteries, rechargeable batteries and other common column batteries are widely used in the market, and can be purchased everywhere in large and small shops and supermarkets, and the price is low. High capacity, but due to the limited diameter and length of the pen, it is impossible to use three column batteries in series. Power, so as How column battery power LED light pen becomes a technical problem to be solved urgently needed in the industry. On the other hand, in the above two patents, the battery, the light-emitting diode and the refill are respectively disposed at the rear, the middle and the front of the sheath, and have the disadvantages of two: one is that the light-emitting diode illuminates the middle of the sheath and The peripheral part, instead of being concentrated around the nib, has more decorative functions than the practical function. Second, the refill is short in length and contains less ink. It is easy to use and needs to be replaced frequently. Not practical enough. Summary of the invention

本发明所要解决的技术问题是针对上述现有技术现状而提供一种采用普通柱式电池作为电源的 LED发光笔。 The technical problem to be solved by the present invention is to provide an LED illuminating pen using a common column type battery as a power source in view of the above state of the art.

本发明所要解决的另一个技术问题是提供一种照明部位集中在笔尖周围的 LED发光笔。 Another technical problem to be solved by the present invention is to provide an LED illuminating pen whose illumination portion is concentrated around the tip of the pen.

本发明所要解决的再一个技术问题是提供一种可采用长尺寸笔芯的 LED发光笔。本发明解决上述技术问题所釆用的技术方案为：该 LED发光笔包括有笔杆及设置在笔杆内的笔芯、电池和至少一个发光二极管，其中电池则位于笔杆的上部，其特征在于所述的电池为柱式电池，所述的发光二极管设置在笔杆的下部，并且在电池和发光二极管之间通过一内装升压电路的升压模块相导电连接，而所述的笔芯则从该升压模块的中央贯穿而过。 Still another technical problem to be solved by the present invention is to provide an LED illuminating pen that can employ a long refill. The technical solution for solving the above technical problem is: the LED light-emitting pen includes a pen holder and a refill disposed in the pen holder, a battery and at least one light-emitting diode, wherein the battery is located at an upper portion of the pen holder, and is characterized in that The battery is a column battery, the light emitting diode is disposed at the lower part of the pen holder, and is in the battery and the hair The photodiodes are electrically connected to each other through a boosting module having a built-in booster circuit, and the refills pass through the center of the boosting module.

所述的升压模块可以是框架式，即包括有分别具有中心孔的上端面、下端面以及至少一根连接上、下端面的支架，其中升压电路即位于支架上，而所述的笔芯即从上下端面的中心孔贯穿而过；所述的升压模块也可以是封闭式，呈具有一中心孔的柱状，其中升压电路即被封装在其内，而所述的笔芯即从该中心孔贯穿而过。 The boosting module may be of a frame type, that is, including an upper end surface having a central hole, a lower end surface, and at least one bracket connecting the upper and lower end surfaces, wherein the boosting circuit is located on the bracket, and the pen is The core is passed through the central hole of the upper and lower end faces; the boosting module may also be closed, in the shape of a column having a central hole, wherein the boosting circuit is encapsulated therein, and the refill is Pass through the center hole.

所述的柱式电池可以是一节，也可以是相互串联的二节。 The column battery may be a section or two sections connected in series.

为了便于安装，所述的发光二极管的发光头部可以封装在一带中央孔的透明块中，而所述的笔芯则从该透明块的中央孔中贯穿而过；并且，所述发光二极管的引脚可以直接升压模块的下端面相电连接，从而将两个部件合二为一，以进一步方便安装。 For ease of installation, the light-emitting head of the light-emitting diode may be encapsulated in a transparent block with a central hole, and the refill penetrating through the central hole of the transparent block; and The pins can be electrically connected to the lower end of the direct boost module, thereby combining the two components into one for further ease of installation.

所述的发光二极管的通断可以简单地通过改变电池与升压模块上触点之间的离合状态来实现，可以借鉴现有 LED手电筒中的结构，最简单的办法就是通过旋紧或旋松笔杆的前后两段来实现，也可以另外设置旋转式开关机构和揿动式开关机构； The on/off of the LED can be realized simply by changing the clutch state between the battery and the contact on the boost module. The structure of the existing LED flashlight can be used for reference. The easiest way is to tighten or loosen. The front and rear sections of the pen holder are realized, and a rotary switch mechanism and a tilting switch mechanism may be additionally provided;

其中，对于采用旋动式开关机构的，可以借鉴现有金属 LED手电筒的设计方案，具体结构为：所述的笔芯采用金属壳体，所述的笔杆包括上笔杆、中笔杆和下笔杆，其中上笔杆、中笔杆为金属材质，下笔杆为透明非金属材质，所述的封装有发光二极管的透明块即设置在下笔杆内，在中笔杆的上端嵌设一绝缘内螺套，上笔杆即通过与该绝缘内螺套的螺紋连接而与中笔杆相连接，柱式电池设置在中笔杆内，电池的上端电极通过一贯穿绝缘内螺套之中心孔的导电杆与上笔杆相连，电池的下端电极与则与笔芯的上端相接触，笔芯的上部套有一弹簧，该弹簧的上端与笔芯的上端膨起部相抵，下端则与升压模块的上端面相抵； Wherein, for the rotary switch mechanism, the design scheme of the existing metal LED flashlight can be borrowed, and the specific structure is as follows: the refill adopts a metal casing, and the pen holder includes an upper pen, a middle pen and a lower pen. The upper pen and the middle pen are made of metal, and the lower pen is made of transparent non-metal material. The transparent block enclosing the light emitting diode is disposed in the lower pen, and an insulating inner screw is embedded in the upper end of the middle pen. Connected to the middle pen holder by screwing with the insulating inner nut sleeve, the column battery is disposed in the middle pen rod, and the upper end electrode of the battery is connected to the upper pen rod through a conductive rod penetrating through the central hole of the insulating inner screw sleeve, the battery The lower end electrode is in contact with the upper end of the refill, the upper part of the refill is sleeved with a spring, the upper end of the spring is opposite to the upper end of the refill, and the lower end is opposite to the upper end surface of the boosting module;

这样，当上笔杆旋动到位直至与中笔杆的上端面相接触时， LED的电路即为通路，而只要旋松上笔杆使其与中笔杆的上端面相分离， LED的电路即为断路； Thus, when the upper pen is rotated into position until it contacts the upper end surface of the middle pen, the circuit of the LED is a through path, and as long as the upper pen is loosened to be separated from the upper end surface of the middle pen, the circuit of the LED is an open circuit;

上述结构如果应用于自动出芯铅笔上时，即所述的笔芯为具有自动出芯机构的自动铅笔芯，还可作以下结构调整，在所述的上笔杆上端再增设一具有复位弹簧支承的笔罩，所述的导电杆截面设计成 "十"字型，导电杆的上端穿出上笔杆的中心孔并与笔罩相抵，导电杆的下部则套设有复位弹簧，复位弹簧的下端抵在所述的绝缘内螺套上，如果需要出芯，就先旋松上笔杆，使上笔杆具有上下活动的余地，此时，只要揿动上笔杆伸缩，就能通过导电杆、柱式电池使自动铅笔芯发生伸缩，从而实现自动出芯；同时，由于此时上笔杆已处于旋松状态，即 LED的电路为断路状态，因此更适合在无需 LED照明的白天使用，而需要 LED照明时，只要简单地旋紧上笔杆即可。 If the above structure is applied to the automatic core pencil, that is, the refill is a automatic pencil core having an automatic core-out mechanism, the following structural adjustment can be performed, and a return spring support is further added to the upper end of the upper pen holder. The pen cover is designed to have a "ten" shape, the upper end of the conductive rod passes through the center hole of the upper pen and abuts against the pen cover, and the lower part of the conductive rod is sleeved with a return spring, and the lower end of the return spring On the insulating inner threaded sleeve, if the core needs to be cored, first loosen the upper rod to make the upper rod have the space for up and down movement. At this time, as long as the upper rod is tilted, the conductive rod and the column can be passed. The battery causes the automatic pencil lead to expand and contract, thereby achieving automatic core-out; at the same time, since the upper pen is in a loose state, that is, the LED circuit is in an open state, it is more suitable for daytime use without LED illumination, and LED illumination is required. When you simply tighten the upper pen.

而对于揿动式笔，可以采用最常见的由揿座、揿芯及转芯构成揿动式旋转伸缩机构；所述的该揿动式旋转伸缩机构可以设置在笔杆的中部，具体采用如下结构- 所述的笔芯采用金属壳体，所述的笔杆包括上笔杆、中笔杆和下笔杆，其中上笔杆、中笔杆为金属材质，下笔杆为透明非金属材质，所述的封装有发光二极管的透明块即设置在下笔杆内，上笔杆的上端设置有一带回复弹簧的金属按钮，并由封盖住上笔杆的金属帽限位，所述的柱式电池即位于该金属按钮之下，并且电池的上端电极与金属按钮的下端相接触，电池的下端电极则与笔芯的上端相接触，笔芯的上部套设有由绝缘材质的揿座、揿芯和转芯构成的揿动式旋转伸缩机构，其中转芯的下端设置有金属套，该金属套的内壁具有簧片与笔芯始终保持接触，下端具有向一侧外伸的触片，而位于揿动式旋转伸缩机构之下的升压模块则在其上端面则具有对应的凸起触点，在升压模块之下还设置有一套在笔芯外的弹簧，弹簧的另一端抵在中笔杆下部的内台阶上； For the swaying pen, the most common slewing type rotary telescopic mechanism is composed of the sley, the core and the rotating core; The swaying rotary telescopic mechanism may be disposed in the middle of the pen holder, and specifically adopts a structure in which the refill adopts a metal casing, and the pen holder includes an upper pen, a middle pen and a lower pen, wherein the upper pen, The middle pen is made of metal, and the lower pen is made of transparent non-metal.

The other end of the booster module is further provided below the outer cartridge set spring, the spring abuts the step in the inner lower portion of the sheath;

所述的中笔杆与上笔杆之间可以直接以螺紋连接方式连接，但为了便于制造和装配，所述的中笔杆与上笔杆之间可以通过一金属连接套相连接，该金属连接套的下端插固在中笔杆内，金属连接套的上端则与上笔杆螺纹连接； The middle pen and the upper pen can be directly connected by a screw connection, but for the convenience of manufacture and assembly, the middle pen and the upper pen can be connected by a metal connecting sleeve, and the lower end of the metal connecting sleeve Inserted in the middle pen, the upper end of the metal connecting sleeve is screwed with the upper pen;

同样为了便于制造和装配，笔杆的结构还可以有以下改进：所述的中笔杆内可以紧配一底部带内台阶的金属衬套，所述的弹簧下端即抵在该金属衬套的内台阶上；所述的上笔杆上部可以紧配一底部带内台阶的金属弹簧座，所述的复位弹簧下端即抵在该金属弹贊座的内台阶上； Similarly, in order to facilitate the manufacture and assembly, the structure of the pen holder may also have the following improvements: The middle pen holder may be tightly fitted with a metal bushing with a stepped bottom portion, and the lower end of the spring is placed against the inner step of the metal bushing. The upper part of the upper pen can be tightly fitted with a metal spring seat with a step inside the bottom, and the lower end of the return spring is placed on the inner step of the metal bullet seat;

上述这种结构，通过合理设定每笔芯伸缩一次的转芯旋转角度及金属衬套之中央孔的局部内凸数量，还可以有笔芯出芯时 LED发光或不发光两种状态；比如，设定为每笔芯伸缩一次，转芯旋转 90° ，而金属衬套之中央孔的局部内凸为呈 180° 相对设置的两个，则每次笔芯伸出时 LED发光，每次笔芯缩回时 LED熄灭；又如，仍然设定为每笔芯伸缩一次，转芯旋转 90° ，而金属衬套之中央孔的局部内凸只有一个时，则第一次揿动后笔芯伸出时 LED发光，第二次揿动后笔芯回缩时 LED熄灭，第三次揿动后笔芯伸出时 LED不发光，第四次揿动后笔芯回缩时 LED也不发光，而第五次揿动则与第一次相同，如此循环往复。 In the above structure, by reasonably setting the rotation angle of the core of each of the reels and the number of local concavities of the central hole of the metal bushing, it is also possible to have two states of LED illumination or no illumination when the refill is out; , set to retract each core once, the core rotates 90°, and the local inner convex of the metal bushing is 180° relative to each other, then the LED shines each time the refill is extended, each time When the refill is retracted, the LED is extinguished; for example, it is still set to retract each reel once, the core is rotated by 90°, and the central inner hole of the metal bush has only one local convexity, then The LED is illuminated when the refill is extended after one tilting. When the refill is retracted after the second tilting, the LED is extinguished. After the third retraction, the LED does not emit light after the refill is extended. After the fourth reel, the refill is returned. The LED does not emit light when it is time-lapsed, and the fifth time is the same as the first time, and so on.

与现有技术相比，本发明由于采用了升压模块，因此只用一节 1.5V的普通柱式电池就能使白光 LED发光，发光二极管设置在笔杆的下部使得照明部位集中在笔尖周围，而笔芯从升压模块的中央贯穿而过的设计，则使得长笔芯在 LED发光笔中的使用成为可能。附图说明 Compared with the prior art, the present invention adopts a boosting module, so that a white LED can be illuminated by only one 1.5V ordinary column battery, and the LED is disposed at the lower part of the sheath so that the illumination portion is concentrated around the nib. The design of the refill from the center of the boost module makes it possible to use a long refill in the LED illuminating pen. DRAWINGS
