Abstract
An illuminated logo unit (300) includes a reflective board (320), a pattern panel (301), an illuminating device (310), and a reflective film (305). The pattern panel is arranged over the reflective board, and the reflective film is disposed under the pattern panel opposite to the reflective board. Much light emanating from the illuminating device is reflected more than once by the reflective film and the reflective board before it reaches the pattern panel. This enhances the overall brightness and uniformity of light beams of the illuminated logo unit. Even at night, the illuminated logo unit can be clearly viewed. The illuminated logo unit may be used for applications such as in a billboard, a logo displayed on a vehicle, and so on.
