Description

A kind of rotating LED illuminating pen

Technical field

It is the lettering pen of lighting source with LED (light emitting diode) that the utility model relates to a kind of, relates to a kind of rotating LED illuminating pen specifically.

Background technology

In recent years along with the fast development of LED technology, in the market, having occurred many is the LED light pen of lighting source with LED, this LED light pen is because of having lighting source, and make original common pen can be used as miniature flashlight, help in the dark to write, seek article, see other purposes such as wrist-watch or reading letter, thereby be subjected to many consumers' favor.But many LED light pens all are to utilize the shell of pen core as a conductive component, in the luminous loop of LED, the pen core top directly contacts with a utmost point of battery, another utmost point of battery contacts with switch module again, when reality is used, people write with the nib of pen core, and pen core is upwarded pressure, this pressure directly is transferred to battery from pen core, then be transferred to the switch module that is positioned at the battery top, because people's size of exerting oneself has difference when writing, and power thrusts is also indefinite, many times needs deflection, the indefinite pressure of this activity just causes the relative penholder activity of switch module easily, this will influence switch module and penholder, perhaps with penholder in the good conducting of contact, cause when writing the light-emitting flash of LED indefinite, can not stabilized illumination.Therefore, power on some pen cores can not conduct on the battery and can guarantee that the luminous stable LED light pen of LED is invented, as application number is the Chinese invention patent application " a kind of LED light pen " of 200710068049.0 (publication number is CN101032907A), discloses a solution.This LED light pen makes pen core not participate in the luminous loop of LED by parts such as metal pen core cap on power spring, the pen core, negative spring are set, and the power that acts on the pen core can't upwards conduct on the battery because of metal pen core cap.The pen core of this LED light pen is to control its relative penholder and move up and down by being arranged on the outer rotary components of pen core, and LED controls by being arranged on switch module on the battery that it is luminous, also be the knockout of pen core and the luminous separately independent control of LED, this makes LED light pen inside that parts such as luminescence component need be set and makes structure become complicated, and has increased manufacturing cost.

On the other hand, go out the LED light pen of pen core in the market with knock-type and drawing mode, its parts that participate in conduction are more, and structure and parts cooperate more complicated, and cost is not low yet.And also do not have a kind of power that can prevent to act on the pen core to be transmitted on the battery at present, can control the luminous LED light pen of knockout and LED by rotation simultaneously again.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of structure simple more rotating LED illuminating pen at above-mentioned prior art present situation, it can realize simultaneously that by rotation the knockout of pen core and LED's is luminous, the power that can also prevent to act on the pen core simultaneously is transmitted on the battery, guarantees that LED is luminous stable.
