Rotating LED illuminating pen

Abstract

The invention discloses a rotary LED luminescent pen, comprising a pen holder(1), a refill(2), a rotary component(6), a battery(3), a luminescent circuit board(4) and an LED(5); wherein, the upper pen holder(11) of the pen holder(1) can rotate oppositely to a central pen holder(12), the positive pole(31) of the battery(3) is connected with the positive input end(41) of the luminescent circuit board(4), the negative pole(32) of the battery(3) is connected with the negative input end(42) of the luminescent circuit board(4) through the conducting spring(95) of the negative pole and an insulating rotary sleeve(7) is arranged between a lower rotary component(62) of the rotary component(6) and the central pen holder(12); the insulating rotary sleeve(7) is provided with a metal sheet(8); the upper pen holder(11) is communicated with the metal sheet(8) through a conducting part. Compared with the prior art, the invention can realize the knock out of the refill and the luminescence of LED through the subtle match and design of the upper pen holder, the conducting part, the metal sheet and the rotary pen holder, which has the advantages of subtle and compact structure design and simpler structure.

Description

technical field [0001] The invention relates to a writing pen with an LED (light emitting diode) as a light source, in particular to a rotating LED light emitting pen. Background technique [0002] In recent years, with the rapid development of LED technology, many LED luminous pens with LED as the light source have appeared on the market. This kind of LED luminous pen has a light source, so that the original ordinary pen can be used as a miniature pen. Flashlights help to write in the dark, find items, watch watches or read letters and other purposes, so they are favored by many consumers. However, many LED light-emitting pens use the shell of the refill as a conductive part. In the LED light-emitting circuit, the top of the refill is directly in contact with one pole of the battery, and the other pole of the battery is in contact with the switch assembly. When people write with the nib of the refill, the refill is subjected to upward pressure, and this pressure is directl...

AI Technical Summary

Problems solved by technology

The refill of the LED luminescent pen is controlled to move up and down relative to the pen holder through the rotating assembly arranged outside the refill, and the LED is controlled to emit light through the switch assembly arranged on the battery, that is, the refill and the refill. The light emission of the LED is controlled separately and independently, which makes it necessary to install light emitting components and other components inside the LED light pen, which makes the structure complicated and increases the manufacturing cost.

[0003] On the other hand, currently on the market, the LED luminescent pens that use push-type and stretch-type refills have many parts involved in conduction, the structure and parts are more complicated, and the cost is not low.

At present, there is no LED luminous pen that can prevent the force acting on the pen core from being transmitted to the battery, and can simultaneously control the core and LED luminescence by rotating.
