Rotating LED illuminating pen

Abstract

The invention discloses a rotary LED light-emitting pen, which comprises a pen holder (1), a pen core (2), a rotating assembly (6), a battery (3), a light-emitting circuit board (4) and a light-emitting diode (5), wherein the pen holder The upper penholder (11) in (1) can rotate relative to the middle penholder (12), and the positive end (31) of the battery (3) is electrically connected with the positive input terminal (41) of the light-emitting circuit board (4), and the battery (3) ) negative terminal (32) is electrically connected to the negative input terminal (42) of the light-emitting circuit board (4) through the lower negative conductive spring (95), and the lower rotating member (62) in the rotating assembly (6) is connected to the middle An insulating rotary bushing (7) is tightly arranged between the penholders (12), and a metal sheet (8) is arranged on the insulating rotary bushing (7), and the upper penholder (11) and the metal sheet (8) are connected through conductive parts conduction. Compared with the prior art, the present invention achieves the core out of the pen core and the light of the LED through the ingenious design of the upper pen holder, the conductive part and the metal sheet by rotating the pen holder. Simple.

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.
