Abstract
The utility model discloses a kind of illuminating pen cap, comprise for whole device being fixed to support on penholder, be used for judging the control module of light intensity, be used for providing the lighting module of light, be used for controlling the key-press module of whole device switch, provide the power module of power supply as whole device; The output of described control module connects the input of lighting module, and described control module comprises interconnective photo resistance, voltage comparator, potentiometer.The utility model may be used on various types of pen, reusable, has saved resource.Under dim environment, this device can turn on lamp automatically; When light is strong, this device also can be closed lamp automatically, has saved electric energy, when running into dim environment, can directly install on pen, can start to write, effectively very convenient.When family uses, coordinate desk lamp to use the light that can improve better when writing, eliminate the shade that hand blocks.
Description
Technical field
The utility model relates to a kind of illuminating pen cap.
Background technology
The existing cap for brush is as a kind of daily culture articles for use, and a part for pen, only has the effect of general protection pen, thus acts on more single people in the middle of daily study with work, inevitably needs to write with pen.Guarantee there is good lighting condition very important.But also there are problems in existing lighting solutions.
Light pen in the market, its luminous component is connected with pen, cannot take off, and therefore when needs illumination functions time, the personnel that write just use this pen only, can not use other pen.When there is no light pen, write under dim environment, then must have desk lamp.When there being desk lamp, also may because the blocking of hand when writing, occur shadow region, impact is write.
Utility model content
Technical problem to be solved in the utility model is that to provide a kind of structure for the deficiency of background technology simple and automatic sensing light intensity can control light emitting diode light on and off, so solve illumination and light more weak write environment.
The utility model is for solving the problems of the technologies described above by the following technical solutions
A kind of illuminating pen cap, comprises for whole device being fixed to support on penholder, is used for judging the control module of light intensity, is used for providing the lighting module of light, is used for controlling the key-press module of whole device switch, provides the power module of power supply as whole device; The output of described control module connects the input of lighting module.
Preferably, described control module comprise connect successively photo resistance, voltage comparator, potentiometer.
Preferably, described lighting module is light emitting diode.
Preferably, described button is vertical 6*6*7 button by module.
Preferably, described power module is CR2032 button cell.
Preferably, described photo resistance is 5516.
Preferably, described voltage comparator is LM393.
Preferably, described potentiometer is 3296.
The utility model adopts above technical scheme compared with prior art, has following technique effect:
1) the utility model may be used on various types of pen, reusable, has saved resource.
2) under dim environment, this device can turn on lamp automatically; When light is strong, this device also can be closed lamp automatically, has saved electric energy.
3) the utility model is easy to carry, and when running into dim environment, can directly install on pen, can start to write, effectively very convenient.
4) there is this device, when family uses, coordinate desk lamp to use the light that can improve better when writing, eliminate the shade that hand blocks.
Accompanying drawing explanation
Fig. 1 is simulation drawing of the present utility model;
Fig. 2 is system block diagram of the present utility model;
Fig. 3 is the circuit diagram of the utility model control module.
Number in the figure is specific as follows: 1-button, 2-button cell, 3-photo resistance, 4-voltage comparator, 5-light emitting diode.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail:
A kind of illuminating pen cap, comprises for whole device being fixed to support on penholder, being used for judging the control module of light intensity, being used for providing the lighting module of light to select light emitting diode 5, be used for controlling the button 1 of whole device switch, provide the power module of power supply to select button cell 2 as whole device here here; Described support is made up of the cylinder that contains a bottom surface, and described lighting module is light emitting diode 5, and described button is vertical 6*6*7 button by module, and described power module is CR2032 button cell.The output of described control module connects the input of lighting module, and described control module comprises interconnective 5516 photo resistance, LM393 voltage comparator, 3296 potentiometers.
As shown in Figure 1, when the personnel that write prepare to write, this device is enclosed within penholder, and presses "ON" key, device is started working.
As shown in Figure 2, the output of described photo resistance 3 connects voltage comparator 4, the output connecting luminous diode 5 of described voltage comparator, described button is connected between power module button cell 2 and photo resistance 3, for whether controlling the operation of whole device.
As shown in Figure 3, when intensity of illumination dies down, the resistance of photo resistance can rise, the anti-phase input terminal voltage of voltage comparator raises, when being elevated to setting value, the output of voltage comparator just changes high level into by low level, and then makes lighting module work, namely lights light emitting diode, there is provided light to the personnel of writing in time, guarantee that he can clearly see write content.After the personnel of writing write, the personnel of writing press "Off" key, and device is quit work.
This device is applied widely: the utility model can be arranged on all kinds of pen, can reuse.The light on and off of automatic control lamp: this device can automatic sensing light power and control light emitting diode light on and off, therefore, write personnel and only need press "ON" button before the use, after using, press "Off" button.Eliminate shade: this device irradiates the region around hand, eliminates the dash area sheltered from by hand.
