On the case panel of light-emitting window both sides, two reflectors are provided with the housing, two reflectors are respectively arranged on corresponding
On the beam projecting angle of light source.
According to above scheme, the light source is the bar shaped illuminator of unidirectional light extraction, and the reflective surface of reflector is in the arc of indent
Shape face, the reflective surface of reflector corresponding to the beam projecting mouth sensing of light source, and then make the focal spot of two reflectors in inspection
On the center vertical line of viewport and light-emitting window.
According to above scheme, the light source is provided with rotary shaft, and the both ends of rotary shaft are connected with the side plate of housing respectively, and
The adjuster that driving light source rotates is provided with housing.
According to above scheme, the reflector includes some reflecting strips, and reflecting strips are provided with rotary shaft, the both ends of rotary shaft
It is connected respectively with the side plate of housing, and the adjuster for driving some reflecting strips to rotate is provided with housing.
According to above scheme, prism is provided with the light-emitting window, the both ends of prism are flexibly connected with the side plate of housing respectively,
The up and down adjuster of driving prism is provided with housing.
The present invention has the beneficial effect that：The present invention is rational in infrastructure, and light source and reflector are integrated in housing, pass through regulation
Light source, reflector and refracting prisms obtain the change of exposure focal length, ensure the coverage rate and the irradiation uniformity of light, can improve
Determination details definition, obtain contrast height, the image without speck dazzle；Overall structure is simple, easy to adjust, can meet existing
Line sweep observation system requirement.

Embodiment
Technical scheme is illustrated with embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of light supply apparatus for Surface testing of the present invention, including housing 1, the housing 1
Backboard on offer inspection door 11 between two parties, offered on the panel of housing 1 corresponding to light-emitting window 12；It is provided with the housing 1
Two light sources 2, two light sources 2 are symmetrically provided with two instead on the panel of housing 1 of the both sides of light-emitting window 12, in the housing 1
Tabula rasa 3, two reflectors 3 are respectively arranged on the beam projecting angle of corresponding light source 2；The inspection door 11 is formed with light-emitting window 12
CCD camera scan channel, two light sources 2 project light in the case where corresponding reflector 3 focuses on reflex, below light-emitting window 12
Realize and focus on, so as to improve brightness and the uniformity that line clears off source 2, ensure time for exposure and the imaging effect of CCD camera；It is built-in
Light source 2 and the structure of reflector 3 can realize that quick ground structure is expanded and angle, focus adjustment according to scanning demand.
The light source 2 of the present invention is the bar shaped illuminator of unidirectional light extraction, and the reflective surface of reflector 3 is in the arc of indent
Face, the reflective surface of reflector 3 corresponding to the beam projecting mouth sensing of light source 2, and then make the focal spot of two reflectors 3 in inspection
On the center vertical line of viewport 11 and light-emitting window 12；The light that the light source 2 is sent reflects on the curved reflection year of reflector, from
And form and focused on to improve exposure brightness and the uniformity below light-emitting window 12.
