Apparatus and method for heating at a distance by light radiance includes a support and narrow-beam lamps mounted on the support in a matrix of lines and columns. Each of the lamps produce a luminous beam having a central axis of projection. The lamps in each column can be oriented to make their central axes converge to a first focal area. The lamps in each line can be oriented to make their central axes converge to a second focal area. |
