ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a combination light pen, and more particularly to such a combination light pen, which comprises a water chamber defined in a lower barrel around an ink cartridge, and display items floating in a liquid in the water chamber.
Conventionally, a pen is simply a writing instrument used in writing with ink. However, it is not practical to write with a pen in the dark. There are commercially available light pens, which provide sufficient illumination when writing in the dark. These light pens commonly comprise a bulb, a battery, and a button controlled to connect/disconnect the circuit between the bulb and the battery. However, because these light pens provide the same effect, a special design or an added function must be provided so as to attract consumers to buy.
SUMMARY OF THE INVENTION
It is the main object of the present invention to provide a combination light pen, which produces an attractive advertising effect when operated to emit light. According to one aspect of the present invention, the combination light pen comprises an upper barrel, a pen cap and a connector fastened to top and bottom ends of the upper barrel, a LED and battery circuit assembly mounted in the upper barrel, a push-button switch mounted in the pen cap and operated to turn on/off the LED, a transparent lower barrel fastened to the connector to hold an ink cartridge and a transparent conical socket, wherein the lower barrel comprises a water chamber disposed around the ink cartridge, a liquid filled in the water chamber, and display items floating in the liquid inside the water chamber. According to another aspect of the present invention, graphic device means is provided at an inside wall of the lower barrel around the longitudinal receiving hole for advertising.
