<p>The present invention relates to a linear beam irradiator, more specifically to a linear beam irradiator for using light conductor, comprising a light conductor having light permeability, a light refraction & reflection area 2 provided on one side face in the longitudinal direction of said light conductor, and a light source 8 provided in a way to cover the light refraction & reflection area 2, as well as a light source disposed at one end or both ends of said light conductor. This construction makes it possible to irradiate a linear light beam from the other side face of the light conductor corresponding to said light refraction & reflection area 2. With this construction, it becomes possible to reduce the deviation of illuminance of said linear light beam, sharply improve the transmission efficiency of light and greatly reduce the number of LED chips disposed at the light source. Moreover, this also enables a cost reduction.</p> |
