摘要：
A lighting device (50) comprises a light source (40) e.g. LED, a convex reflector (43) for receiving light from the LED (40), and a concave reflector (41) for receiving light from the convex reflector (43). A relatively narrow angled light beam from the LED (40) is diverged by the convex reflector (43) and then converged by the concave reflector (41) into a relatively broader parallel light beam. The two reflectors (43 & 41) may be replaced by plano-concave and convex lens (143 & 141) respectively.
