Description

Tunnel dome light source

Technical Field

The utility model relates to a light source, especially a tunnel dome light source.

Background

Dome light source and oblique light source among the prior art are separately, and not only the space that occupies the board is great, and oblique light source can not filter the light column moreover, can't be to conventional gold card paper, silver-colored cardboard, highlight post bottom paper and radium-shine paper formation of image, because there is the light column to disturb during the formation of image, causes the false retrieval. Meanwhile, a dome light source in the prior art can only support one camera to capture images, and different imaging effects cannot be met.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the tunnel dome light source combines the dome light source and the oblique light source, can support two cameras to pick pictures on the same light source, and can filter the interference of light columns.

The utility model provides a technical scheme that its technical problem adopted is: a tunnel dome light source comprises a shell, wherein an arch diffuse reflection plate is arranged in an inner cavity of the shell, an opening is formed in the bottom of the shell, light emitting sources are arranged on two sides of the opening in the bottom of the shell, light rays emitted by the light emitting sources irradiate the arch diffuse reflection plate, and the arch diffuse reflection plate refracts the light rays; the side of the shell is provided with a strip-shaped light inlet hole, a support is fixed on the outer surface of the shell, a reflector is rotatably arranged on the support, and the reflector reflects light through the light inlet hole to form an imaging point in the shell.

Further say, arch diffuse reflection board surface be provided with the diffuse reflection coating, the light that the light pearl sent shines on the diffuse reflection coating like this, through refraction many times, on shining the product again, can eliminate the shadow completely to reach the effect of filtering the light post.

Still further say, the light emitting source be LED lamp pearl for luminous the product that shines the bottom, let the camera can clearly adopt the picture.

Still further say, the side of light emitting source and top of casing top, arch diffuse reflection board all be provided with heat abstractor, heat abstractor be fin and radiator fan, can effectively dispel the heat to the light source inside and outside.

The utility model has the advantages that the defects in the background technology are solved, light is taken from the dome light source from a special angle, and is reflected and imaged by the reflector, irradiated on the surface of a product, and light beams are filtered; two cameras can be supported above the light source for imaging, so that two different imaging effects are met; the product applicability of the product inspection machine is improved, and the special detection requirements of the light beam product are met.

Detailed Description

The invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

A tunnel dome light source as shown in fig. 1-2, comprising a housing 1, wherein an arch diffuse reflection plate 2 is arranged in an inner cavity of the housing 1, an opening 3 is arranged at the bottom of the housing, light sources are arranged at two sides of the opening at the bottom of the housing, light emitted by the light sources irradiates the arch diffuse reflection plate, and the arch diffuse reflection plate refracts the light; the surface of the arched diffuse reflection plate is provided with the diffuse reflection coating, so that light emitted by the light beads irradiates the diffuse reflection coating, and after multiple refractions, the light irradiates a product, the shadow can be completely eliminated, and the effect of the light filtering column is achieved. The light emitting source is an LED lamp bead 4 for emitting light to irradiate the product at the bottom, so that the camera can clearly pick pictures.

The side of the shell is provided with a strip-shaped light inlet hole 5, the outer surface of the shell is fixed with a support 6, and the support is rotatably provided with a reflector 7. The fixing mode of the bracket is as shown in figure 1, the bracket can be fixed on the front end surface and the rear end surface of the shell, and the reflector is clamped with the bracket through a rotating pin, so that the multi-angle adjustment of the reflector can be realized; the reflector reflects the light through the light inlet hole, the camera makes an imaging point under the dome light through the reflection of the reflector, and the position of the imaging point can be changed by adjusting the angle of the reflector.

Two cameras can be supported above the shell for imaging, and two different imaging effects are met.

The side surfaces of the light beads, the top of the shell and the upper part of the arched diffuse reflection plate are provided with heat dissipation devices, and the heat dissipation devices are heat dissipation fins and heat dissipation fans 9 and can effectively dissipate heat inside and outside the light source.

The dome light source is used for diffusion and uniform illumination, and shadow can be completely eliminated by multiple reflections of the hemispherical inner wall. The reflector is utilized, one side of the dome light source is provided with the light inlet hole, and the imaging point is reflected in the dome through the light inlet hole, so that the shadow generated by the light column is eliminated. The structure that this light source used is to make up the dome with the oblique reflection, can realize that a light source is compatible two kinds of formation of image effects simultaneously, saves the cost, saves installation space, and the formation of image point adjustable range is great. Compared with the prior art, can realize compatible white card paper, grey card paper formation of image, and can compatible conventional gold card paper, silver card paper, strong light column base stock, radium-shine paper formation of image.

While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
