LUMINAIRE |
摘要 |
A luminaire for projecting an image comprises a housing (1) having a light emission window (2). The housing (1) accommodates a light source (3), an optical system (4) for directing light originating from the light source (3) along a longitudinal axis (5), and an image-forming surface (6) which is positioned orthogonally with respect to the longitudinal axis (5). According to the invention, the light source is a LED (3), and the optical system (4) comprises a collimating element (14) for collimating the light originating from the LED (3). Preferably, the luminaire comprises only one LED (3) which, during operation, has a luminous flux of at least 5 lm. Preferably, the housing (1) also comprises a focusing lens (15) for focusing the collimated light originating from the collimating element (14) on the image-forming surface (6) and, preferably, a projection lens (7, 7') for projecting an image of the image-forming surface (6). Preferably, parts of the collimating element show total internal reflection. The luminaire according to the invention is a compact, lightweight, low-energy and low-maintenance luminaire. |
