A lighting module, particularly for a portable lamp, including an array of light emitting diodes (LEDs) (15), and a transparent cover (12) arranged in front of the LEDs (15), the cover (12) having plurality of lenses (16) on the inner surface thereof providing a respective lens (16) in the light emission field of each LED (15), and a diffuser screen (17) is positioned between the LEDs (15) and the cover (12) and can be moved linearly across the LEDs (15) so as to diffuse the light emission from at least some of the array or all of the array as is desired. The diffuser screen (17) comprises a flexible polymeric material which is stored around a roller (18) located to one side of the cover (12). |
