<p>Light sources, e.g. LEDs, are fitted at the ends of the bar shaped reflector (1). The latter consists of a flat reflector (4) along which reflecting prisms are positioned and an elliptical section (12) with reflecting sides (6,7) and light outlet (5). Light reflected from the prisms is concentrated at a focal point (16) whilst light not incident to the prisms is reflected by the sides to focal points (15,17).</p> |
