Abstract
The utility model provides a laser screen system, comprising a reception screen, a laser and a conical mirror which is used for reflecting the emission laser of the laser to generate laser rays with a field angle not less than 180 DEGs. The laser rays are parallel to the reception screen. According to the laser screen system, the emission laser of the laser is reflected by the conical mirror, the laser screen with a field angle not less than 180 DEGs is obtained, which is parallel to the reception screen, the laser screen emits light to the whole reception screen from up to down, no dark zone without light exists, and the laser rays possess good continuity and consistency.
Description
Technical field
The utility model relates to a kind of laser light curtain system.
Background technology
Existing laser light curtain system, comprise that mainly the laser rays that is arranged on two laser instruments generations that receive place, centre position, screen top is parallel with the reception screen, subtended angle factor due to the shoot laser line of laser instrument, its exist laser rays irradiation less than the dark space, also can because assembly relation overlaps discontinuous, inconsistent situation, need to expend time in and adjust simultaneously.
Summary of the invention
The purpose of this utility model be overcome existing laser light curtain system have the dark space and easily overlap discontinuous, inconsistent, the problem that need to expend time in and adjust.
For reaching above-mentioned purpose, the utility model provides a kind of laser light curtain system, comprise receiving screen and a laser instrument, its special character is, also comprises one in order to the shoot laser that reflects described laser instrument, to produce a subtended angle large or equal the conical surface mirror of the laser light curtain of 180 °; This laser rays is parallel with described reception screen.
Above-mentioned conical surface mirror is fixed on the top of described reception screen so that described laser light curtain from the top of described reception screen to downward-extension.
Above-mentioned laser instrument is arranged on the Axis Extension line of described conical surface mirror, its pupil and this conical surface mirror over against.
Above-mentioned laser instrument is fixed on the below of the Axis Extension line of this conical surface mirror, and its pupil is towards the conical surface that is in its axis below of this conical surface mirror.
Above-mentioned reception screen is projection screen or display screen or metope.
Be provided with a junction between the top of the top of above-mentioned laser instrument and described conical surface mirror, realize that by this connecting portion this laser instrument is connected with the one of conical surface mirror, this connecting portion is annular.
The utility model has the advantages that: by the shoot laser of conical surface mirror reflection laser, obtain a subtended angle more than or equal to the laser light curtain of 180 °, it is parallel with the reception screen, and shine downwards above certainly receiving screen, can be according to complete whole reception screen, do not exist irradiation less than the dark space, and this laser rays has good continuity and consistance.

Embodiment
For being overcomes existing laser light curtain system to have the dark space and easily overlap the problem that discontinuous, inconsistent needs expend time in and adjust, the present embodiment provides the laser light curtain shown in a kind of Fig. 1,2 system, comprise receiving screen 1 and a laser instrument 4, also comprise a shoot laser 5 in order to reflection laser 4, to produce a subtended angle large or equal the conical surface mirror 3 of the laser light curtain 2 of 180 °; This laser light curtain 2 is parallel with reception screen 1; This conical surface mirror 3 is fixed on the top that receives screen 1, so that laser light curtain 2 is from receiving the top of screen 1 to downward-extension; Laser instrument 4 is arranged on the Axis Extension line of conical surface mirror 3, its pupil and this conical surface mirror 3 over against.
Certainly, the below that laser instrument 4 can also be fixed on the Axis Extension line of this conical surface mirror 3 (is that laser instrument 4 and conical surface mirror 3 must not be coaxially set, as long as guarantee the shoot laser 5 of conical surface mirror 3 energy reflection lasers 4, forming laser light curtain 2 get final product), its pupil guarantees namely that towards the conical surface 6 that is in its axis below of this conical surface mirror 3 shoot laser 5 incides on reflecting surface below the axis of conical surface mirror 3.
The reception screen 1 here can be TV screen, the LD screen of projection screen or display screen such as oversize etc., certainly can also be directly can receive the face of projection as the reception screen with metope etc.
Be provided with a junction 7 between the top of the top of laser instrument 4 and conical surface mirror 3, realize that by this connecting portion 7 this laser instrument 4 is connected with the one of conical surface mirror 3, this connecting portion 7 is annular.
High-visible by Fig. 3, laser instrument 4 mainly is made of the circuit board 11 that is arranged on laser tube 9, the lens combination 10 in housing 8 and is arranged on housing 8 left ends, and conical surface mirror 3 is connected with its right-hand member by connecting portion 7.
Shoot laser 5 by conical surface mirror 3 reflection lasers 4, obtain a subtended angle more than or equal to the laser light curtain 2 of 180 °, as shown in Fig. 4 (in figure, annular broken is laser light curtain 2), it is parallel with reception screen 1, and certainly receive screen 1 top and shine (extension) downwards, can be according to complete whole reception screen 1, do not exist irradiation less than the dark space, and this laser light curtain 4 has good continuity and consistance.Between bottom surface 12 shown in Fig. 4 and reception screen 1, a segment distance is arranged when practical application, designed, designed gets final product according to actual needs.
