Description

Optical fiber light pen

In the light-emitting pen, the pen nib and LED chip are present side by side to reduce the volume generated by minimizing the inconvenience caused by the production and the user inconvenience.

The present invention relates to a writing pen designed for writing at night or in a dark place. In general, the pens currently in use can only be written under bright lights such as daylights or lamps, and memos can be written at night or in dark places. It is inconvenient to take notes because they are not visible even if you try to write or write, and in some cases, you can take notes while illuminating the portable flashlight, but in this case, you must hold the pen and the note with both hands. Therefore, there was a problem that it is very inconvenient to perform the work of taking notes alone while illuminating the flash.

In order to solve this problem, there are publicly available 96-831 1/2 and practical publication 97-6462 1/3. Since the LED chip should be located directly on the side of the pen nib and emit light on the surface to be written, the pen nib Due to the side-by-side and side-by-side LED chips, there was a problem in reducing the volume of writing instruments, and it was not enough to completely eliminate the blind spots due to the limitation of design and shadow of the pen nib.

In recent years, the number of portable items that an individual carries as needed while traveling is on the rise. As a result, some industries are investing enormously in making small and light in order to satisfy consumer's desire to buy products. The light pen also aims to minimize the size of the pen in order to minimize discomfort in the possession by breathing.

The optical fiber light emitting pen of the present invention for achieving the above object is detachably coupled to the upper and lower cylinders (23. 19), the pen case 21 and the carrier 18 of the lower cylinder is built in the pen As the light transmitting material, one end of the carrier and at least one light emitting material 20 is accommodated in the carrier, and the other end of the at least one light emitting material is inserted into the rear optical fiber fixing opening 24 of the pen core 17. The pen nib support bar 16 is installed between the pen nib and the optical fiber fixing bar 15 to easily attach and detach the upper and lower cylinders.

At the end of the light emitting material fixed in the optical fiber fixing opening, one or more lenses 22 for collecting light are assembled to maintain a distance to collect light, and an LED chip 14 for emitting light to the lens is provided. Located in the lens direction. The LED chip fixing bar 13 is located at the rear of the LED chip, the LED chip fixing and reflecting surface, and the battery 12 is located at the rear of the LED chip fixing bar, and the ON / OFF switch is attached to the rear side of the pen case. When the rear ON / OFF switch is set to ON while having the contacts between the LED chip inside the pen case and the pen chip, the LED chip emits light by the battery power and the emitted light passes through the lens located in front of the LED chip. It is collected and conveyed to one end of the light emitting material fixed to the optical fiber fixing opening. The transmitted light illuminates the other end of the light emitting material contained in the carrier according to the characteristics of the light emitting material.

The optical fiber light-emitting pen of the present invention as described above can reduce the volume of the pen due to the movement of the LED chip to the rear end of the pen nib, making it easy to carry the user as well as setting the design according to manufacturing extensively. You can do it.
