A photoradiator has an elongate light conducting member which is supplied with converged light at one end thereof. Light radiating portions are arranged on the light conductor so that the light propagating through the light conductor may stream out in any desired light amount distribution along the axis of the light conductor. The radiating portions comprise spaced annular strips or spiral strips each being made of a material whose refractive index is larger than that of the light conductor. A mirror is positioned at the other end of the light conductor to reflect components of the incoming light which are substantially parallel to the axis of the light conductor, thereby promoting efficient radiation of the incoming light through the radiating portions.

Photoradiator comprising: an elongate light conducting member for conducting converged light from one end to the other end thereof; radiating means for radiating the light therethrough to the ambience radially outwardly of the light conducting member, said radiating means comprising a plurality of radiating means positioned at spaced locations on the light conducting member; and reflecting means for reflecting light incident thereon, said reflecting means being positioned at said other end of the light conducting member with a reflecting surface thereof faced inwardly of the light conducting member; said radiating means being constructed to set up a selective quantity distribution of the radiated light at least along an axis of the light conducting member; said radiating means being constructed such that the total quantity of light si radiated through each of the radiating means after being introduced into the light conducting member and light si′radiated through said radiating means after being reflected by the reflecting means, si+si′, has a specific value relative to the other radiating means, in which a selected amount of light Si to be radiated from the radiating means satisfies the equation: Si=(1+Bi)S where [Figure] n is the number of the radiating means, Bi is a preselected value, and [Figure]
