Pen with lamp

Abstract

The invention discloses a pen with a lamp. The pen comprises a first end and a second end, and a writing part is arranged on the second end. An LED lamp is arranged on the first end and comprises a battery, a light emitting circuit board, a buckle connecting piece, a plug pin, an LED light emitting device and a raised heat dissipation component. The light emitting circuit board is electrically connected with the battery, the buckle connecting piece and the plug pin respectively, and the buckle connecting piece is electrically connected with the LED light emitting device and is used for fixingthe LED light emitting device to one side of the light emitting circuit board. The LED light emitting device comprises a plurality of light emitting diodes. The raised heat dissipation component is fixedly arranged on the back of the LED light emitting device, and an annular groove is formed between the raised heat dissipation component and the LED light emitting device. The raised heat dissipation component is used for deducing the heat emitted by the LED light emitting device. The light emitting surface of the LED light emitting device is connected with an optical fiber, and the optical fiber extends to the direction of the second end along the first end of the pen. The light emitted by the LED light emitting device is guided to the second end of the pen through the optical fiber.

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...

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
