The illuminated backboard comprises a frame and a translucent front panel, both of which have the general outline of a conventional basketball backboard. A lamp inside the frame and proximate the basketball hoop illuminates the front panel. Planar ribs of translucent material extend between the front panel and the back wall of the frame. The front panel glows with less intensity in the areas in front of the ribs. The ribs can be located to radiate from the region of the hoop, so when the lamp illuminates the front panel the ribs appear as darker rays emanating from the hoop. The illuminated backboard may be an independent and separate backboard having its own mounting to a pole or roof, or it may be made to fasten to a conventional backboard. In the latter case, the hoop is joined to the conventional backboard to eliminate all stresses on the illuminated backboard. ## Claims ### Claim 1 An illuminated backboard comprising: a. an opaque frame having a flat back wall and a peripheral wall upstanding from the back wall, the peripheral wall having a predetermined outline, a front surface, and a bottom portion; b. a translucent front panel attached to the front surface of the frame peripheral wall and having an outline substantially similar to the outline of the frame peripheral wall, the front panel cooperating with the frame to define a cavity; c. a hoop joined to the frame; and d. light means secured to the frame in the cavity proximate the hoop for illuminating the front panel. ### Claim 2 (depends on 1) The illuminated backboard of claim 1 wherein: a. the frame is fabricated with a platform that is spaced a predetermined distance from the bottom portion of the peripheral wall and with wall means for joining the platform to the bottom portion of the frame peripheral wall, the platform, wall means, and peripheral wall bottom portion having respective front surfaces that cooperate to form a mounting surface; and b. the hoop is joined to the frame mounting surface. ### Claim 3 (depends on 2) The illuminated backboard of claim 2 wherein the light means is secured to the frame platform. ### Claim 4 (depends on 1) The illuminated backboard of claim 1 further comprising at least one rib made of translucent material within the cavity and lying in a plane that extends between the front panel and the frame back wall. ### Claim 5 (depends on 4) The illuminated backboard of claim 4 wherein: a. there are a plurality of ribs; and b. the ribs lie in respective planes that intersect in the region of the light means. ### Claim 6 (depends on 5) The illuminated backboard of claim 5 wherein the ribs have unequal lengths. ### Claim 7 (depends on 2) The illuminated backboard of claim 2 wherein the front panel is interposed between the hoop and the frame mounting surface. ### Claim 8 Apparatus for playing a basketball game comprising: a. a translucent planar front panel having the outline of a basketball backboard; b. a frame attached to the front panel and cooperating therewith to define a cavity, the frame having an outline of a basketball backboard; c. a hoop joined to the frame; and d. light means in the cavity for illuminating the front panel. ### Claim 9 (depends on 8) The apparatus of claim 8 wherein: a. the frame comprises: i. a peripheral wall having a front surface that attaches to the front panel; and ii. platform means for cooperating with the peripheral wall front surface to define a mounting surface; and b. the hoop is joined to the frame mounting surface. ### Claim 10 (depends on 9) The apparatus of claim 9 wherein the light means is secured to the platform means. ### Claim 11 (depends on 8) The apparatus of claim 8 further comprising a plurality of translucent planar ribs located in the cavity and extending generally perpendicular to the plane of the front panel. ### Claim 12 (depends on 11) The apparatus of claim 11 wherein the ribs lie in respective planes that intersect in the region of the light means. ### Claim 13 (depends on 9) The apparatus of claim 9 wherein the front panel is interposed between the hoop and the frame mounting surface. ### Claim 14 In combination with a basketball backboard, an illuminated backboard comprising: a. a frame having a peripheral surface with an outline that is substantially identical to the outline of the basketball backboard, the frame being attached to the basketball backboard; b. a translucent planar front panel attached to the frame and cooperating therewith to define a cavity; c. light means inside the cavity for selectively illuminating the front panel; d. a basketball hoop; and e. bracket means secured to the basketball backboard for supporting a hoop at a predetermined location relative to the illuminated backboard, so that the illuminated backboard is not subjected to any stresses from the hoop. ### Claim 15 (depends on 14) The combination of claim 14 further comprising a plurality of translucent ribs located in the cavity and lying in respective planes that extend generally perpendicular to the plane of the front panel. ### Claim 16 (depends on 15) The combination of claim 15 wherein the planes of the ribs intersect in the region of the light means. ### Claim 17 (depends on 16) The combination of claim 16 wherein the light means is located in the cavity proximate the hoop. ### Claim 18 A method of illuminating a basketball backboard comprising the steps of: a. providing a conventional basketball backboard with a hoop; b. removing the hoop from the conventional basketball backboard; c. attaching a frame to the conventional basketball backboard; d. attaching a translucent front panel to the frame and forming a cavity by the cooperation of the front panel with the frame; e. securing a bracket to the conventional basketball backboard; f. joining the hoop to the bracket proximate the front panel; and g. energizing a source of illumination in the cavity and illuminating the front panel. ### Claim 19 (depends on 18) The method of claim 18 comprising the further steps of: a. providing a plurality of planar translucent ribs; and b. locating the ribs within the cavity with their respective planes intersecting. ### Claim 20 (depends on 19) The method of claim 19 comprising the further step of locating the ribs within the cavity with their respective ribs intersecting in the region of the hoop.
