Abstract

A method and apparatus for integrating an illuminated sign system with a dasher board in a hockey rink. The illuminated sign system includes an outer frame with an impact resistant transparent sheet secured to a front surface of the outer frame. The sign system includes a display panel member having a white front surface and a plurality of apertures therein. The display panel member includes a circuit board assembly having a plurality of LED trios positioned proximate the rear surface of the display panel member so that LED trios register and protrude through a corresponding aperture in the display panel member. The illuminated sign system includes a power supply and a controller for controlling the power supplied to specific LEDs in each of the LED trios. In addition, the controller controls the intensity emitted by the LEDs to thereby manipulate the color contrast with the white front surface of the display panel member. The illuminated sign system also includes shock absorbers for absorbing the impact of hockey play to the outer frame and the transparent sheet.

Claims

1. An LED illuminated dasher board assembly comprising:

a thin display panel member having a white front surface and a rear surface, said panel member having a plurality of apertures therein to accommodate LEDs;

an outer frame support for said panel member, said frame being rectangular in shape and protruding away from the front surface of said panel member;

a rigid transparent sheet contiguous with a front surface of said outer frame; and

a circuit board assembly having printed circuitry on at least one surface thereof and LED receptacles for said LEDs, said LED receptacles numbered and grouped to be at the same spacing as the apertures in said panel member so that LEDs provided in said receptacles are in register and protrude through said panel member apertures whenever said circuit board is in a proximate position to said rear surface of said panel member.

2. The assembly of claim 1, wherein said LEDs comprise a plurality of LED trios individually grouped as trio clusters, wherein said trio clusters are arranged in a matrix.

3. The assembly of claim 2, wherein each of said LED trios comprises a red LED, a green LED and a blue LED.

4. The assembly of claim 2, wherein each LED trio collectively comprises a white light source.

5. The assembly of claim 2, wherein said plurality of LED trios are spaced vertically and horizontally to form a matrix of pixels.

6. The assembly of claim 1, further comprising a power supply and a controller configured to control said power supply to said LEDs.

7. The assembly of claim 6, wherein said controller is configured to control said LEDs in at least one of an on position and an off position so that said LEDs collectively emit a predetermined image.

8. The assembly of claim 7, wherein said LEDs comprise a plurality of LED trios, wherein said LED trios not needed for said predetermined image each emit white light.

9. The assembly of claim 6, wherein said controller is configured to control said LEDs required to collectively emit a predetermined image comprising red light, green light and blue light and wherein said controller is configured to control an illuminated intensity emitted from each of said LEDs.

10. The assembly of claim 9, wherein said controller is configured to provide contrast between said predetermined image and said white front surface of said panel member by adjusting said illuminated intensity.

11. The assembly of claim 1, wherein said outer frame includes a sub-frame for supporting said thin display panel member and said circuit boards.

12. The assembly of claim 11, wherein said sub-frame comprises an upper sign support and a lower sign support.

13. The assembly of claim 1, wherein said outer frame support comprises at least one shock absorber for absorbing impact to said outer frame support and said transparent sheet.

14. The assembly of claim 13, wherein said at least one shock absorber is positioned between said outer frame support and said panel member to substantially protect said panel member and said circuit board assembly from impact vibration.

15. The assembly of claim 13, wherein said at least one shock absorber comprises at least one of a resilient member and a rigid member.

16. The assembly of claim 15, wherein said resilient member comprises rubber.

17. The assembly of claim 1, wherein said transparent sheet is substantially impact resistant.

18. The assembly of claim 1, wherein said transparent sheet is spaced from said panel member a distance greater than the length of said LEDs protruding through said apertures of said panel member.

19. The assembly of claim 1, wherein said circuit board assembly includes a plurality of circuit boards, wherein each circuit board edge abuts with at least another circuit board edge when in said proximate position of said rear surface of said panel member.

20. The assembly of claim 19, wherein said LED receptacles in each of said plurality of circuit boards are each substantially equally spaced a uniform distance in said rows and columns.

21. The assembly of claim 20, wherein a distance from a corner receptacle of one circuit board to an adjacent corner receptacle of an abutting adjacent second circuit board is substantially equal to said uniform distance.

22. The assembly of claim 1, wherein said panel member comprises a plurality of panel members, wherein each panel member abuts end to end to form a continuous matrix display of said LEDs protruding through said apertures of each panel member, wherein said LEDs are spaced a distance substantially uniform from one another over said continuous matrix display formed from said plurality of panel members.

26. The method of claim 25, wherein said controlling comprises controlling visual contrast between said illuminated LEDs and said white front surface by gamma correction of said LEDs.

27. The method of claim 25, wherein said controlling comprises increasing said intensity illuminated from said LEDs.

28. The method of claim 25, wherein said controlling comprises adjusting said intensity illuminated from said LEDs to visually contrast with said white front surface.

23. A dynamic image display assembly comprising:
