Abstract
The utility model provides a kind of semiconductor laser light resource, comprise housing, be arranged on the semiconductor laser module in housing and be arranged on the light-emitting window of housing forward end, the cross sectional shape of light-emitting window is the shape after the circular arc of the symmetry clipping round upper and lower end parts in the horizontal direction, and the short optical axis intersection of the shoot laser of this circular arc and described laser module.The utility model has the advantages that: by the design of the cross sectional shape to light-emitting window, light on the short optical axis of effective interception, Output of laser is gathered, the uniformity of the light improved in effective aperture, take full advantage of luminous energy, decrease the waste of luminous energy and the interference to sight line.
Description
Technical field
The utility model belongs to laser technology field, is specifically related to a kind of semiconductor laser light resource.
Background technology
Current semiconductor laser light resource, as semiconductor laser takes aim at tool, the apparatus such as torch, its light-emitting window is all circular mostly, and the light spot shape that the light-emitting window of this circle and semiconductor laser light resource produce differs, the shape approximation rectangle of the laser facula that semiconductor laser light resource produces, and based on the circular light-emitting window of current light source apparatus, the laser of the short optical axis direction of laser is not gathered, its border along circular light-emitting window is caused to be penetrated, especially the emergent light of the upper and lower of direction of illumination is in, almost do not help much for the object that people will be illuminated, validity is very poor, all slattern, but also interference can be caused to the sight line of people.Tracing it to its cause, is that the design of light-emitting window causes the optical uniformity in effective aperture poor.
Utility model content
The purpose of this utility model is the light beam by tackling short optical axis direction, to improve the uniformity of light in effective aperture, improves the utilization of light and reduces without using up interference to sight line.
For this reason, the utility model provides a kind of semiconductor laser light resource, comprise housing, be arranged on the semiconductor laser module in housing and be arranged on the light-emitting window of housing forward end, its special character is, the cross sectional shape of described light-emitting window is the shape after the circular arc of the symmetry clipping round upper and lower end parts in the horizontal direction, and the short optical axis intersection of the shoot laser of this circular arc and described laser module.
The utility model has the advantages that: by the design of the cross sectional shape to light-emitting window, light on the short optical axis of effective interception, Output of laser is gathered, the uniformity of the light improved in effective aperture, take full advantage of luminous energy, decrease the waste of luminous energy and the interference to sight line.
Accompanying drawing explanation
Fig. 1 is the cutaway view of a kind of semiconductor laser torch that embodiment one provides.
Fig. 2 is the schematic cross-section of the light-emitting window of the torch of semiconductor laser shown in Fig. 1.
Description of reference numerals: 1, housing; 2, semiconductor laser module; 3, light-emitting window.
Embodiment
For the light beam by the short optical axis direction of interception, to improve the uniformity of light in effective aperture, improve the utilization of light and reduce without using up interference to sight line, present embodiments provide the semiconductor laser torch shown in a kind of Fig. 1, comprise housing 1, be arranged on the semiconductor laser module 2 in housing 1 and be arranged on the light-emitting window 3 of housing 1 front end, composition graphs 2 is visible, the cross sectional shape of this light-emitting window 3 is the shape after the circular arc of the symmetry clipping round upper and lower end parts in the horizontal direction, and the short optical axis intersection of the shoot laser of this circular arc and laser module 2, be about to the circular arc be on short optical axis direction clip, thus shorten the path of short optical axis in light-emitting window 3, light on short optical axis is exported in advance relative to existing circular light-emitting window, the light on short optical axis direction is equivalent to compress, make these light more concentrated, thus effectively reduce the diffusion of the light on short optical axis direction, decrease the luminous energy distributed in light exit direction, improve the outgoing luminous energy of the left and right directions of light, enhance the illuminance of the object that will illuminate for people, decrease light on the light beam above-below direction that exists in prior art to the interference of people simultaneously.
In sum, be not difficult to find out, this semiconductor laser light resource that the present embodiment provides is by the design to the cross sectional shape of light-emitting window, light on the short optical axis of effective interception, Output of laser is gathered, the uniformity of the light improved in effective aperture, take full advantage of luminous energy, decrease the waste of luminous energy and the interference to sight line.
More than exemplifying is only illustrate of the present utility model, does not form the restriction to protection range of the present utility model, everyly all belongs within protection range of the present utility model with the same or analogous design of the utility model.
