Abstract
The utility model provides a laser for an interactive projecting hand-written inductive light curtain, and the laser comprises a housing, a laser module group disposed in the housing along the axial direction, a total reflection device disposed at the right end of the housing and disposed on an emergent light path of an exit pupil of the laser module group, and a conic mirror which is disposed on the right end of the housing and on the reflected light path of the total reflection device, and can generate laser rays with field angles more than 180 degrees. The laser provided by the utility model employs the conic mirror for generating laser rays with field angles more than 180 degrees through reflection, and the laser rays can cover the whole curtain or the whole cloth cover or wall surface of a curtain wall. Moreover, during installation, the laser just needs to be installed at the center of the top of the curtain or the curtain wall. Without any try, the laser can be installed in place, saves time and labor, and is convenient to use.
Description
Technical field
The utility model belongs to laser application technique field, is specifically related to the hand-written induction light curtain of a kind of interactive projection laser instrument.
Background technology
The hand-written induction light curtain of existing interactive projection uses at least two laser projecting apparatuss that are arranged on curtain or curtain wall top to carry out transmission, there is the zone of intersection of two bundle laser, the zone of intersection exists without Ear Mucosa Treated by He Ne Laser Irradiation region, can produce dark space, affect drop shadow effect, for fear of this kind of phenomenon, general higher to the installation requirement of laser projection instrument, each installation all needs to attempt repeatedly just fixing best installation site, takes time and effort inconvenience.
Summary of the invention
The purpose of this utility model is to overcome the hand-written induction light curtain of existing interactive projection can not realize separately the full wood of projected area and cover (irradiation) and cause installing loaded down with trivial details and awkward problem.
For this reason, the utility model provides the hand-written induction light curtain of a kind of interactive projection laser instrument, comprise housing and the laser module in holder housing vertically, also comprise total reflection device on the emitting light path that goes out pupil that is arranged on housing right-hand member and is placed in laser module, be arranged on housing right-hand member and be placed in the conical surface mirror that produced subtended angle on the reflected light path of this total reflection device is greater than the laser rays of 180 °.
The optical axis angle at 45 ° of above-mentioned total reflection device and laser module.
On the reflecting surface of above-mentioned total reflection device, be coated with total reflection film.
Above-mentioned total reflection device is completely reflecting mirror.
The setting of above-mentioned conical surface mirror impinges perpendicularly on the conical surface mirror reflected light path of total reflection device.
Above-mentioned housing comprises end face and bottom surface, end face is equilateral triangle, this leg-of-mutton drift angle is placed in the rear end of laser module, and the axis of the center line of this drift angle and laser module is parallel and be on same vertical plane, and bottom surface is that right-hand member end is the rectangle of circular arc.
The hand-written induction light curtain of the interactive projection laser instrument that the utility model provides, adopt the reflection of conical surface mirror to produce the laser rays that subtended angle is greater than 180 °, can cover whole cloth cover or the metope of whole curtain or curtain wall, and while installation, only need to be arranged on curtain or curtain coping middle position place, can be in place without any trial, time saving and energy saving, easy to use.
Below with reference to accompanying drawing, the utility model is described in further details.

Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is that the B of Fig. 1 is to view.
Description of reference numerals: 1, housing; 2, laser module; 3, total reflection device; 4, conical surface mirror; 5, reflecting surface; 6, end face; 7, bottom surface; 8, right-hand member end; 9, screw; 10, the strong point.
Embodiment
The full curtain that can not realize separately projected area in order to overcome the hand-written induction light curtain of existing interactive projection covers (irradiation) and causes installing loaded down with trivial details and awkward problem, the present embodiment provides the hand-written induction light curtain of the interactive projection shown in a kind of Fig. 1 laser instrument, comprise housing 1 and the laser module 2 in holder housing 1 vertically, also comprise the total reflection device 3 on the emitting light path that goes out pupil that is arranged on housing 1 right-hand member (being positioned at one end of person's with the aid of pictures right-hand side in figure) and is placed in laser module 2, be arranged on housing 1 right-hand member and be placed in the conical surface mirror 4 that produced subtended angle on the reflected light path of this total reflection device 3 is greater than the laser rays of 180 °.For the ease of installing and realize as much as possible all the utilizing of shoot laser of laser module 2, in the present embodiment, the optical axis angle at 45 ° (incident angle that is laser is 45 °) of total reflection device 3 and laser module 2.On the reflecting surface 5 of total reflection device 3, be coated with total reflection film.Conventional total reflection device 3 is completely reflecting mirrors, certainly, can be according to design and application occasion needs, select other materials of plating reflectance coating on reflecting surface as total reflection device 3, as aluminium alloy, steel plate etc., these materials can cause the loss of more light certainly.
In order to ensure all reflected light all or be parallel to curtain or curtain wall projection, in the present embodiment, the setting of conical surface mirror 4 impinges perpendicularly on conical surface mirror 4 reflected light path of total reflection device 3.
By finding out in Fig. 2,3, housing comprises end face 6 and bottom surface 7, end face 6 is equilateral triangle, this leg-of-mutton drift angle is placed in the rear end (i.e. left end shown in figure) of laser module 2, and the axis of the center line of this drift angle and laser module 2 is parallel and be on same vertical plane, bottom surface 7 is rectangles that right-hand member end 8 is circular arc.When use, fixing by triangle and the fixing composite of end face 6.
In sum, be not difficult to find out, the hand-written induction light curtain of the interactive projection laser instrument that the present embodiment provides, adopt the reflection of conical surface mirror to produce the laser rays that subtended angle is greater than 180 °, can cover whole cloth cover or the metope of whole curtain or curtain wall, and install time only need to be arranged on curtain or curtain coping middle position place, can be in place without any trial, time saving and energy saving, easy to use.
More than exemplifying is only to illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, within the every and same or analogous design of the utility model all belongs to protection domain of the present utility model.
