20080198581 | TOUCH SENSOR TYPE LIGHT-EMISSION WRITING INSTRUMENT - Provided is a touch sensor type light-emission writing instrument such as a ball point pen or an automatic pencil, which includes an LED (Light-Emitting Diode) unit which is turned on or off by a touch sensor without special illumination at dark places or at night. The touch sensor type light-emission writing instrument includes an LED unit having two light-emission portions which are embedded in a leading-end opening portion of a body accommodating a pencil lead or a ball point internal chamber filled with viscous ink, and which emit light. The negative polarity of the LED unit is directly connected to a battery through a metal plate, a spring etc., in the writing instrument, and the positive polarity thereof is linked on an integrated-circuit (IC) board between the LED unit and the battery. The LED unit is turned on or off by detection of a touch sensor. Accordingly, in comparison with the conventional light-emission writing instrument employing the mechanical switching unit, the touch sensor type light-emission writing instrument employing the touch sensor type switching unit is simple in view of the structure, to thus decrease the number of trouble occurrence, and employs the LED unit having two light-emission portions, to thus provide good brightness so that shadow does not occur as well as to thus facilitate a switching operation of the LED unit, to offer a simply manipulative light-emission writing instrument. | 08-21-2008 |
20080205038 | Chalk holding device with light - A chalk holding device for marking up dry walled walls of a building uses a pole that has a chalk holder at one end wherein chalk is received within the holder and. locked in place via a compression ring. The pole may be threadably attached to an additional extension pole on the end opposite the chalk holding end. A light source is attached to the pole either by clamping the light source and attaching the clamp to the pole via another clamp, via adhesion or welding, or other appropriate attachment method, or the light source is an LED ring such that the pole passes through a central opening of the LED ring with the ring attached to the pole. | 08-28-2008 |
20090129065 | PEN WITH MAGNIFIER - A pen is provided with optical magnifying capabilities, and, optionally, further includes an illuminating device. The pen functions as a writing tool so that a user can easily hold it to write. A double prismatic lens is disposed inside a lower casing of the pen and by manipulating a selector switch, a user can control the magnifying level. An LED is disposed inside casing of the pen and a light producing assembly (LPA) is disposed in a lower pen sleeve. Correspondingly, by pushing the selector switch, the LPA is electrically connected to the battery and to a switch to turn on or off an LED. | 05-21-2009 |
20090196021 | DUAL MODE LUMINOUS BALL PEN - A dual mode luminous ball pen is disclosed. The luminous pen includes a pen shaft; a tapered transparent tip portion disposed on a proximal end of the shaft; a refill, a switch portion, a lamp, a control portion, and a button. The switch portion disposed inside the pen shaft and connected to the tip portion for rotating a sleeve. The lamp includes at least a cell, a first light emitting diode (LED), and a second LED, and can be rotated together by the sleeve to supply/cut-off a power supplied by the cell to the LEDs. The control portion is disposed on the switch portion to turn on one of the first and second LEDs. The button is depressed into the pen shaft to rotate the control portion. | 08-06-2009 |
20100103653 | RETRACTABLE LAMP PEN OPERATING IN ALTERNATE MODES - A lamp pen comprises a lower body, an upper body attachable to the lower body, a refill and a lamp disposed in the lower body, a conductive spring disposed about the pen refill, a rotating body assembly disposed in the upper body and having a battery, conductive terminals, and a rotating wheel, a conductive guiding sleeve, a conductive element, and a push button assembly. | 04-29-2010 |
20100265698 | PEN HAVING A DECORATION - A pen having a decoration includes a decoration on a penholder. The decoration contains an illuminator. When the decoration rotates, the illuminator emits light. On the other hand, upon writing with the pen, the illuminator emits the light as well. Therefore, the illuminator will emit the light by this dual switch. | 10-21-2010 |
20110134630 | RETRACTABLE LAMP PEN OPERATING IN ALTERNATE MODES - A lamp pen comprises a lower body, an upper body attachable to the lower body, a refill and a lamp disposed in the lower body, a conductive spring disposed about the pen refill, a rotating body assembly disposed in the upper body and having a battery, conductive terminals, and a rotating wheel, a conductive guiding sleeve, a conductive element, and a push button assembly. | 06-09-2011 |
20110176294 | LIGHTING DEVICE WITH REMOVABLE CLIP - A light producing device, such as a flashlight, may have a clip that is removably attached to a body thereof. The clip may comprise a split ring that substantially encircles the body and has a split therein and may also comprise an elongated portion having a proximal end and a distal end. The elongated portion may be attached to the split ring substantially opposite the split. The clip may be readily removed from the body, such as to better facilitate hand holding of the light producing device, to facilitate maintenance or repair of the light producing device, and/or for storage/transportation of the light producing device. | 07-21-2011 |
20120087112 | WRITING INSTRUMENT PROVIDING ILLUMINATION - A writing instrument providing illumination includes a penholder, a pen core, a solid state lighting source module, and a rotating plate. The rotating plate connects to one end of the penholder. The solid state lighting source module is embedded in the rotating plate which can rotate to a specific angle. A battery providing electrical energy to the solid state lighting source module is arranged inside the penholder. When the rotating plate is turned to a position perpendicular to the penholder the solid state lighting source module is turned on and when the rotating plate is turned to a position adjacent to the penholder the solid state lighting source module is turned off. | 04-12-2012 |
