Pen with illuminating lamp

Abstract

The invention discloses a pen with an illuminating lamp, and relates to the technical field of illumination. The pen comprises a first end and a second end; a writing part is arranged on the second end; an LED lamp body and a heat dissipation assembly are arranged on the first end; the LED lamp body is composed of a plurality of LED light-emitting devices; and the heat dissipation assembly at least comprises a plurality of protruding heat dissipation parts and is used for guiding out heat emitted by the LED lamp body. According to the pen with the illuminating lamp, the LED lamp body is adopted for illumination so that the pen can be used for writing in an environment with enough light illumination, and the writing requirement can still be met when the ambient light is so dark that human eyes cannot recognize; the pen with the illuminating lamp can not only be used for illumination in the writing process but also be used for other illumination, is convenient to carry and is flexible touse; and when one or more light emitting diodes of the LED lamp body break down, not all light emitting diode arrays of the whole LED lamp body need to be replaced integrally, and therefore waste ofraw materials can be avoided.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a pen equipped with an illuminating lamp. Background technique [0002] In the prior art, pens include various types such as fountain pens, ballpoint pens, pencils, and signature pens, but there is no pen that can realize the lighting function. Therefore, the pen in the prior art can only write in an environment with sufficient light illumination, and cannot meet the writing requirements when the ambient light is so dark that the human eye cannot recognize it. And the pen in the prior art only has this function of writing, does not possess other functions, and has a single function. [0003] In addition, the LED lamps used for lighting in the prior art will generate heat during the working process. If the heat cannot be dissipated as soon as possible, it will cause circuit aging and affect the service life. Therefore, the LED lamps used for lighting in the prior art are general...

AI Technical Summary

Problems solved by technology

However, if one or several light-emitting diodes in the array fail, all the light-emitting diode arrays of the entire LED lamp need to be replaced as a whole, which will obviously cause great waste, because many light-emitting diodes are still intact, far from reaching expected service life

[0004] If a single light-emitting diode is replaced, it is a very complicated work in the prior art (caused by the unreasonable structure of the LED lamp itself in the prior art), it needs to consume a lot of time, and not only the single light-emitting diode needs to be removed from the cooling part Remove it from the control circuit and remove it from the control circuit at the same time
