Abstract

The invention provides an LED shadowless pen. The LED shadowless pen comprises a pen shell. A power supply battery is arranged at the tail end of the inner portion of the pen shell, an LED luminous body is arranged at the head end of the inner portion of the pen shell, and the LED luminous body, a power switch and the power supply battery are connected into a closed loop circuit through jumper wires. The head end of the pen shell is detachably connected with the pen shell head, a pen core is arranged in the pen shell, and the head of the pen core penetrates through the pen shell head. The penshell head is made of transparent materials. The holding part on the pen shell is arranged outside the mount part of the LED luminous body. According to the LED shadowless pen, by installing an LED lamp on a pen head, a good writing environment can be provided in a low-brightness environment, and comfortable writing conditions can be provided for eyes; when the pen is held in hand, an LED light line is not affected, shadows are not generated, writing comfort is further improved, eye fatigue is reduced, and the shadows caused by light sources are inhibited; and the LED shadowless pen can further be used as a lighting lamp in a short time.
