PATTERN DISPLAYING DEVICE

摘要

A pattern displaying device includes a light path changing element, a first light source, a second light source, and a control module. The light path changing element has first inclined surfaces to reflect light and arranged into a first predetermined pattern, and second inclined surfaces to reflect light and arranged into a second predetermined pattern. The first light source is operable to emit light toward the first inclined surfaces to display the first predetermined pattern. The second light source is operable to emit light toward the second inclined surfaces in order to display the second predetermined pattern. The control module is electrically connected to the first and second light sources to control the first and second light source to emit light or not.

主权项

1. A pattern displaying device, comprising:
a light path changing element having a plurality of first inclined surfaces that are configured to reflect light incident from a first direction toward a display direction and that are arranged into a first predetermined pattern, and a plurality of second inclined surfaces that are configured to reflect light incident from a second direction toward the display direction and that are arranged into a second predetermined pattern, the first, second, and display directions being different from one another; a first light source that is disposed at a first side of said light path changing element and that is operable to emit light toward said first inclined surfaces in the first direction in order to display said first predetermined pattern toward the display direction; a second light source that is disposed at a second side of said light path changing element and that is operable to emit light toward said second inclined surfaces in the second direction in order to display said second predetermined pattern toward the display direction; and a control module that is electrically connected to said first and second light sources and that is operable to simultaneously control one of said first and second light sources to emit light and the other one of said first and second light sources not to emit light.
