Abstract
The invention relates to a parallel light source. The parallel light source comprises a paraboloid base; the upper surface of the paraboloid base is a smooth paraboloid with high reflectivity; a linear light source is placed in the paraboloid focal point at the left side of the paraboloid; light emitted by the linear light source is horizontally emitted to the paraboloid at the left side; a light path from the linear light source to the paraboloid is provided with light homogenizing pieces and slot gap diaphragms for controlling parallel light emitting angles in sequence; the light emitted by the linear light source is homogenized by the light homogenizing pieces, and irradiates to the paraboloid through the slot gap diaphragms; and the light irradiating to the paraboloid is reflected by the paraboloid to upwards emit parallel light. The invention discloses the parallel light source formed by a method of the linear light source and the paraboloid; and the light source has the characteristics of small volume and low cost.
Description
Technical field
The invention belongs to Automated condtrol technical field of machine vision, particularly a kind of source of parallel light.
Background technology
In Automated condtrol field of machine vision, source of parallel light has the application of its uniqueness.Current source of parallel light is all make with spot light+lens, spot light is positioned at the focus place of lens, and when when requiring visual field larger, equalization is higher, the relative aperture of lens is comparatively large and focal length is also long, cause the volume ratio of whole light source comparatively large, cost is also higher.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, and propose a kind of source of parallel light.
The present invention solves its technical problem and takes following technical scheme to realize:
A kind of source of parallel light, comprise parabola base, the upper surface of this parabola base is smooth and the parabola of high reflectance, parabolic focus place on the left of parabola is mounted with a linear light sorurce, parabola on the left of the light horizontal sheaf that linear light sorurce sends, linear light sorurce to paraboloidal light path is mounted with the slit diaphragm of even mating plate and the control directional light angle of divergence successively, the light that linear light sorurce sends, by being irradiated on parabola by slit diaphragm again after the even light of even mating plate, is irradiated to light on parabola through the backward upper injection directional light of parabolic reflector.
And, be mounted with for the protection of paraboloidal cover glass plate above paraboloidal.
And, be provided with between slit diaphragm and cover glass plate and prevent stray illumination to be mapped to paraboloidal light barrier.
Advantage of the present invention and good effect are:
The present invention proposes one linear light sorurce+paraboloidal method and form a kind of source of parallel light, the feature of this light source is that volume is little, and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Be further described the invention process below in conjunction with accompanying drawing, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of source of parallel light, as shown in Figure 1, comprise parabola base 7, the upper surface of this parabola base is smooth and the parabola 1 of high reflectance, parabolic focus place on the left of parabola is mounted with a linear light sorurce 5, parabola on the left of the light horizontal sheaf that linear light sorurce sends, linear light sorurce to paraboloidal light path is mounted with the slit diaphragm 6 of even mating plate 4 and the control directional light angle of divergence successively, the light that linear light sorurce sends is by being irradiated on parabola by slit diaphragm again after the even light of even mating plate, be irradiated to light on parabola through the backward upper injection directional light of parabolic reflector.
In specific embodiment of the invention, be mounted with for the protection of paraboloidal cover glass plate 2 above paraboloidal, certainly, this cover glass plate can replace by the PE plate of material of high-transmission rate.
In specific embodiment of the invention, be provided with between slit diaphragm and cover glass plate and prevent stray illumination to be mapped to paraboloidal light barrier 3.
