Abstract
An illuminated logo unit (300) includes a reflective device (320), a pattern panel (301), and an illuminator (311). The reflective device includes a bottom portion (323) and a circumferential portion (321). The circumferential portion defines a concavity (360). The pattern panel is disposed over the reflective device, and includes a pattern (304) and a transparent body (302). The illuminating means illuminator is received in the concavity. The illuminated logo unit further includes a transflective film (305) disposed under the pattern panel opposite to the bottom portion. Virtually all light emitting from the illuminating means illuminator is reflected more than once by the circumferential portion, the bottom portion and/or a transflective film before it reaches the pattern, This improves the overall brightness of the illuminated logo unit.
