Time display device
View Patent ↗A time display device which utilizes light beams to display time is disclosed. The time display device at least comprises a timetable panel, an illuminant module, a counter unit, and a control unit. When the counter unit sends a counting result to the control unit, the control unit controls the illuminant module to respectively emit three color light beams projected on the timetable panel through the shielding of at least one shielding structure to form three color image areas with different distances to represent a second, a minute and a hour corresponding to the counting result.
1. A time display device, comprising:
a timetable panel being a concave panel having a center area;
an illuminant module having three light emitting elements, and the three light emitting elements arranged in a vertical sequential order;
a control unit positioned under the timetable panel;
a counter unit positioned on the control unit, and for sending a counting result to the control unit; and
wherein while receiving the counting result, the control unit controls the three light emitting elements to respectively emit three color light beams projected on the concave panel through the shielding of at least one shielding structure to form three color image areas with different distances to represent a second, a minute and a hour corresponding to the counting result.
2. The time display device according to claim 1 , wherein the timetable panel is carved with timing indicators.
3. The time display device according to claim 1 , wherein the illuminant module is a LED module.
4. The time display device according to claim 1 , wherein the shielding structure prevents color light beams of the illuminant module from interfering with each other.
5. The time display device according to claim 1 , wherein the counter unit and the control unit are positioned beneath the center area of the timetable panel.
6. The time display device according to claim 1 , wherein the three light emitting elements are respectively a red LED, a blue LED and a green LED.
7. The time display device according to claim 1 , wherein the counting result is a real time.
8. The time display device according to claim 1 , wherein the vertical sequential order is that the three light emitting elements are respectively positioned at the top of the illuminant module, at the middle of the illuminant module and the bottom of the illuminant module.
9. The time display device according to claim 1 , wherein the three light emitting elements further include a yellow LED, a purple LED and a magenta LED.
10. The time display device according to claim 1 , wherein the different distances are that the three color light beams projected on the concave panel respectively have a longest distance, a shorter distance and a shortest distance to represent the second, the minute and the hour.
11. The time display device according to claim 1 , wherein the three color image areas includes a red image area, a blue image area and a green image area.
12. The time display device according to claim 1 , wherein the timetable panel has a funnel-like shape with a wide board and a narrow area.
13. The time display device according to claim 12 , wherein the wide board and the narrow area are formed a ramp area, and three color image areas are respectively projected on a top portion of the ramp area, a middle portion of the ramp area and a lowest portion of the ramp area.
