Abstract
The invention discloses a short-distance linear light source device based on a linear array scanning camera. The short-distance linear light source device comprises a long-edge outer cover plate, a transparent glass plate, a long-edge inner cover plate, a bar-shaped lens, an aluminum alloy housing, highlighting LED lamps, two-end side cover plates, adjustable fixing bases, a power line inlet and a temperature controller. The highlighting LED lamps are arranged below the bar-shaped lens. The temperature controller is arranged on the outer part of the aluminum alloy housing. By adopting the cylindrical lens, the light source device can make light beams linearly gathered within a three-meter effective working distance and thus enable an illuminated object to locally form narrowband-degree illumination and finally make the illumination on the surface of the illuminated object reach 6000-7000 lumens. The illumination is applied by the linear array scanning camera to acquire image data. The short-distance linear light source device which has the characteristics of low working voltage, low power consumption, high lighting efficiency, extremely short lighting response time, pure light color, and firm structure is suitably applied for detecting printed matters, textile goods, high-precision large workpieces and loading states of railway freight cars, etc. The short-distance linear light source device is suitable for wide popularization.
