LUMINOUS MODULE AND VISUAL INSPECTION SYSTEM USING THE SAME

摘要

The present invention relates to a lighting module capable of obtaining an image by uniformly irradiating light onto entire surface to be inspected of an object to be inspected. According to an embodiment of the present invention, the lighting module comprises: a housing having a dome shaped inner surface; and a lighting unit which is arranged in the housing to indirectly irradiate light onto an object to be inspected by reflecting the light through the inner surface of the housing. The lighting unit includes at least one light source having a wavelength of an ultraviolet area, and the housing includes a dome shaped reflection unit to reflect the light irradiated by the lighting unit and a light source arrangement unit which is formed to protrude toward the inside from the lower end of the domed shape reflection unit. In the light source arrangement unit, one surface where the lighting unit is arranged is formed as an inclination surface, and an angle between the horizontal surface and the inclination surface is in a range of 0° ~ 45°. The object to be inspected has a size in a range of 0.1mm ~ 60mm, and the dome shaped reflection unit has the radius in a range of 20mm to 200mm.
