An illumination device (10) has an elongated array of point light sources (12), a focusing rod (14), and a diffusing rod (16). The focusing rod (14) is positioned adjacent and along the array of point light sources (12), for focusing light into an elongated light distribution pattern. The diffusing rod (16) is positioned adjacent and along the focusing rod (14) for receiving the focused light and diffusing the light into an essentially uniform light intensity distribution pattern, for simulating a tubular lamp having a uniform light intensity distribution. The illumination device may further have a color-converting member (52) for converting a light of a first color emitted by the array of point light sources (12) to a light of a second color, such that the light emitted by the illumination device is of a color that is a combination of the light of a first color and the light of a second color. |
