Rotary intelligent light emitting pen

Abstract

The invention provides a rotary intelligent light emitting pen. The rotary intelligent light emitting pen comprises an intelligent light control part and a writing part, wherein the intelligent light control part is composed of a rotary module, a button battery pack, a photosensitive element, a compact circuit board and a light emitting module and achieves the intelligent illuminating function, and the writing part is composed of a penholder, a pen cap and a refill. According to the rotary intelligent light emitting pen, illumination can be automatically regulated through the photosensitive element, and thus proper writing illuminance can be provided for a user when writing luminance is limited; through the rotary module, a user can set three different work modes including the illuminating mode, the writing mode and the writing light ray compensation mode according to needs and set basic light intensity according to personal adaptation conditions; the rotary intelligent light emitting pen is ingenious and compact in design structure, attractive, low in energy consumption, environmentally friendly and long in service life.

Description

technical field [0001] The invention relates to a rotating intelligent luminescent pen, in particular to an intelligent dimming writing pen using LED as a light source. Background technique [0002] The pen is a necessary tool for people to study and work. For thousands of years, people have been using pens to write documents, letters, and record various materials. However, the use of pens at night is accompanied by various lights and candles. Work and study under lighting or weak light conditions. For example, reporters interviewing, plumbers copying water meters, police checking guards at night, etc., if you hold a flashlight in one hand and a pen in the other hand to write, it is extremely inconvenient and the work efficiency is also very low. [0003] With the rapid development of LED technology, there have been many LED luminous pens using LED as the lighting source in the market, but now the LED luminous pen only controls the on and off of the LED through the switch, ...

Problems solved by technology

For example, reporters interviewing, plumbers copying water meters, and police checking guards at night, etc., if you hold a flashlight in one hand and a pen in the other hand to write, it is extremely inconvenient and the work efficiency is also very low.

[0003] With the rapid development of LED technology, there have been many LED luminous pens using LED as the lighting source in the market, but now the LED luminous pen only controls the on and off of the LED through the switch, and simply realizes the lighting function, such as the application number 95108205.1 (publication number CN1140663), a disclosed luminous pen for controlling LED on and off, and application number 200710307578.1 (publication number CN101214767A) of the Chinese invention patent application "a rotating LED luminous pen", disclosed in the prior art A safer luminescent pen, but it is only a simple realization of the LED light on and off, which cannot meet the automatic adjustment of luminosity under different light conditions. When used for writing, the light intensity will not be adjustable, and the user is not suitable. It can only be used for writing. The function of acting as a flashlight cannot meet the needs of intelligence and humanization
