Abstract
The utility model discloses a pulse type semiconductor laser pen which is composed of a cylindrical housing, a light outlet cover, a laser module, a drive circuit, an insulation block, a battery, a battery cover, etc., wherein the laser module is a semiconductor pumping solid laser tube driven by a pulsed drive circuit. Continuous current voltage output by a button cell arranged behind the insulation block is converted by the pulsed drive circuit into impulse current voltage to be input into the laser module to cause the laser module to work. The utility model adopts the pulse working mode to drive a green laser tube of a semiconductor pumping solid, and the laser tube can be driven by the button cell. The disadvantage that an almost 200 mA electric current is needed to drive the laser tube in the prior art is overcome. Compared with the laser pen adopting two AAA batteries in the present market, the utility model has the characteristics of small volume, light weight and electricity saving. Not only is the heating quantity of the laser tube in working reduced by the laser tube adopting the pulse working mode, but also the occurrence of the problem of degraded performance of the laser tube caused by heat effect is avoided.
Description
Technical field
The utility model relates to a kind of laser pen that is used for aspects such as projector, lantern slide indication picture, literal, amusement, education and teaching.
Background technology
(output light is for green to be used for green glow laser pens such as projector, lantern slide indication picture, literal at present on the market, it is radium-shine to call green glow in the following text), mainly comprise the radium-shine power valve of green glow, optical module and employing two joint AAA batteries, adopt the mode driving laser tube of power supply continuously luminous by driving circuit, the radium-shine not only body of this green glow is big, and does not economize on electricity.
Summary of the invention
The utility model provides a kind of volume little at the above-mentioned defective that prior art exists, and is light and handy, the semiconductor pumped solid green glow of power saving isopulse formula laser pen.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of pulse type semiconductor pumping solid green glow laser pen, form by cylinder shell, bright dipping flap, radium-shine module, driving circuit, insulating spacer, battery, threaded block and battery cover etc.It is characterized in that described radium-shine module is a semiconductor pumped solid green glow laser tube that is driven by pulse driving circuit, described pulse driving circuit is the continuous current voltage that is contained in the button cell output behind the insulating spacer to be changed into pulse current voltage be input to radium-shine module, makes module work (exporting green laser light).
The utility model has following beneficial effect than prior art.
The utility model adopts pulsed mode to drive semiconductor pumped solid green glow laser tube, can use the button cell driving laser tube.The continuous discharge of 3pcs button cell is fed to the driving circuit of laser tube, after IC chip effect in the laser tube driving circuit, the continuous electric signal is converted into pulse signal, simultaneously the electric current of battery is amplified, as long as make battery that the continuous current input of 60～80mA is provided, promptly 3pcs button cell (1.5v/pcs) serves as just energy driving laser tube work of power supply.Therefore having overcome prior art need provide 200mA electric current nearly could drive the defective of Nt.It is little, light and handy to have more volume than the laser pen that adopts two joint AAA batteries on the market at present, characteristics such as power saving.Simultaneously, the laser tube that adopts this pulsed mode to drive has reduced the thermal value of laser tube when work, makes laser tube avoid causing because of thermal effect the problem of degradation.
