Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of multifunctional electric torch that can measuring distance is provided.
The present invention realizes like this, a kind of flashlight that can measuring distance, comprise lamp body and the lamp holder being connected with described lamp body, in described lamp body, be provided with power supply, in described lamp holder, be provided with reflector, in described reflector, be provided with the lighting source being electrically connected to described power supply, in described reflector, be also provided with the range finding light source being electrically connected to described power supply, described range finding light source is electrically connected to a control panel that is positioned at described lamp body, the display screen that described control panel and is positioned at described lamp body outside is electrically connected to, described control panel comprises receiver and the controller being electrically connected to each other, described controller is electrically connected to described display screen, described receiver is for receiving light that described range finding light source the sends light after object reflection, described controller is for measuring light that described range finding light source sends from being transmitted into the time of reception and calculating the distance from described range finding light source to object, described display screen is for showing the distance from described range finding light source to object calculating through described controller.
Further, described lamp body outside is provided with one for switching on and off the first switch of circuit between described lighting source and power supply.
Further, described lamp body outside is provided with one for switching on and off the second switch of circuit between described range finding light source and power supply.
Particularly, described lighting source is LED light source.
Particularly, described range finding light source is infrared light sources or LASER Light Source.
Particularly, described power supply is rechargeable battery.
Particularly, described reflector is bowl-type.
Further, the opening part of described lamp holder is provided with transparent panel.
Particularly, described transparent panel and described lamp holder removably connect or are one-body molded.
In sum, flashlight provided by the invention, not only can play the effect of night illumination, can also be for testing the distance between user and object, and according to the distance of measuring, user knows also to be needed how long could arrive object.
Accompanying drawing explanation
In order to be illustrated more clearly in technical scheme of the present invention, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the stereogram of a kind of flashlight that can measuring distance that the embodiment of the present invention provides;
Fig. 2 is the cutaway view of doing along the axis of the flashlight in Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
As depicted in figs. 1 and 2, the embodiment of the present invention provides a kind of flashlight that can measuring distance, comprise lamp body 1 and the lamp holder 2 being connected with lamp body 1, in lamp body 1, be provided with power supply 3, in lamp holder 2, be provided with reflector 4, in reflector 4, be provided with lighting source 5 and range finding light source 6, lighting source 5 and range finding light source 6 are electrically connected to power supply 3 respectively, the opening part of lamp holder 2 is provided with transparent panel 7, the control panel 8 that range finding light source 6 and is positioned at lamp body 1 is electrically connected to, the display screen 9 that control panel 8 and is positioned at lamp body 1 outside is electrically connected to, control panel 8 specifically comprises receiver and the controller being electrically connected to each other, controller is electrically connected to display screen 9, receiver is for receiving the light of the light that sends of range finding light source 6 after object reflection, controller is for measuring the light that sends of range finding light source 6 from being transmitted into the time of reception and calculating the distance from range finding light source 6 to object, the distance from range finding light source 6 to object of display screen 9 for showing that via controller calculates.
Further, lamp body 1 outside be provided with one for the first switch 11 and of switching on and off circuit between lighting source 5 and power supply 3 for switching on and off the second switch 12 of circuit between range finding light source 6 and power supply 3.
Particularly, lighting source 5 is LED light source or other light sources, and range finding light source 6 is infrared light sources or LASER Light Source, and power supply 3 is rechargeable battery or other conventional batteries, the outside shape of reflection ray such as reflector 4 is bowl-type.
Particularly, transparent panel 7 removably connects with lamp holder 2 or is one-body molded.
When using flashlight night illumination of the present invention, first to press the first switch 11, the first switches 11 and connect circuit between lighting source 5 and power supply 3, power supply 3 gives lighting source 5 power supplies, and lighting source 5 starts luminous, and for night, user provides illumination.
In the time need to measuring user to distance between object, first press second switch 12, second switch 12 is connected circuit between range finding light source 6 and power supply 3, power supply 3 gives range finding light source 6 power supplies, range finding light source 6 sends infrared ray or laser, infrared ray or laser are reflected back after arriving object, receiver on control panel 8 receives infrared ray or laser, controller on control panel 8 is measured infrared ray or laser from being transmitted into the time t of reception, and the distance d=c * t/2(c calculating from range finding light source 6 to object is infrared ray or the aerial spread speed of laser), the distance d that controller calculates shows through display screen 9 again, user is by observing display screen 9, just can find out the position at its place and the distance between object.
