BILLIARD LIGHT

CROSS REFERENCE TO RELATED APPLICATIONS

This application is a non-provisional application which hereby claims priority to U.S. Provisional Application Serial No. 63/239,357 filed on August 31 , 2021 , the disclosure of which is hereby incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

Generally, when lighting a billiard table, the state of the art has been limited either to illuminate with a centrally hung chandelier of some type which typically casts a disproportionate concentrated illumination toward the middle of the playing surface or blankets the entire area above the table with an overly diffused light in an attempt to create an environment of even lighting across the playing surface. In practice, neither of these approaches is optimal for filming, playing or training on a billiard table.

The billiard table surface, unlike a conference room table, has two distinct depths. The table bed sits below the nose of the rail cushion by 35-37mm. To improve playability and enhance the quality of any presentation of the game, the nose of the cushion is an important feature of the table that needs to be carefully and specifically lit in order to be clearly visible from a wide range of perspectives

Employing mirrors and diffusers within light sources in billiard table lighting, scatters rays laterally which softens the shadows and floods light under the rail, which creates a situation where it is difficult to visually discern the “nose” of the cushion against the backdrop of the table bed, because both surfaces become lit equally brightly and both surfaces are covered by the same fabric. Lit with this approach, it becomes extremely difficult to discern the precise location of the rubber “nose” of the cushion against the backdrop of the table bed from a majority of overhead perspectives. When the depth of the cushion boundary is not rendered clearly on television, it is difficult for the fans to follow the action, and the production suffers greatly. In order to solve this problem, a completely opposite objective is required. Instead, there is a need for a lighting system which creates a hard shadow between the nose of the cushion, all around the table perimeter, to contrast its depth against the playing surface behind it. Using mirrors to redirect rays horizontally or employing diffusers designed to scatter the light, does exactly the opposite of what is necessary to achieve which is a hard light line providing a stark demarcation of the nose of the cushion.

SUMMARY OF THE INVENTION

One embodiment of the invention relates to an overhead lighting platform designed to facilitate precise illumination and provide for the aligned mounting of and control of precise LED and laser projections on and around a billiard playing arena. The target projection area is not limited to the top playing surface of the table, but also includes the sides of the table, rails, cushions, and the surrounding flooring in the playing space.

The platform described has precision alignment capability as well as the ability to fine-tune the position and alignment of all mounted components, including perimeter lighting sources and centrally directed light emitting devices (laser points/lines and/or LED projectors, as well as strategically placed sensors to capture light, sound, temperature and humidity. The mounting rig, called a “spine”, uses an integrated laser line to perfectly align and calibrate its base position. Lasers and any other devices that require precision-aligned mounting to be easily centered over the table and fixed into place in a variety of useful and novel applications.

The downward focused light rays directed by the lenses create a hard shadow directly under it, that renders the nose of the cushion very clearly against the table bed. The lens helps to control the spread of light to create an even distribution that falls off relatively narrowly and certainly without flooding light under the rail cushion on the opposite side of the one being directly lit from above. Because of the fact that the adjacent light segments work together to concentrate the light more strongly into the corners. Depending on the height that the fixture is hung above the table, there is a necessity to block different amounts of light, in a controlled fashion, from regions along the various lengths of the perimeter so that, overall, while light rays remain focused to create the hard shadow needed directly below, their output is optimized to reduce hot spots. The exact pattern of the light blocking filter all around the perimeter of the fixture, depends on the spread of the lens being used and the height that the fixture to the table. If the focused lens concentrates too much light into a particular region, the filter is moderated to balance the undesirable contrast. Controlling the focus angle and intensity of the beams is the objective which is very different from a diffuser which spreads light around carelessly which would only serve to diminish the visibly reduce the definition of the subject cushion on the cushion across from the segment directly below the overhead lens. Lit in this way, the billiard table playability and production quality is improved. Thus, filters and lenses are used to sharpen the light instead of diffusers which soften the light.

When filming billiards for live television or streaming production, it is not only necessary to illuminate the playing surface of the table, but also important to control exactly how lighting is projected onto the entire stage - including where the athletes walk around and shoot from. The platform and rig allows for LED sources and devices to be mounted, not only inside the bounds of the frame, but also extended outwards (via telescoping extensions to the “spine” and “ribs”) and outside of it as well. In addition, inward and outward-facing scoreboard displays are mountable to enable an immersive and interactive gaming experience for the users and fans.

The overhead platform described is flexible enough to handle a wide range of use cases where extremely precise positioning of overhead projections are needed. In a billiard application, exactly placed points, lines, and images using devices/sources including (laser diodes, lines, or LED projectors) are useful and desirable to have but extremely time-consuming and difficult to deploy, align and calibrate. For any billiard game, it is critical to mark the playing surface with specific key points and lines on the surfaces of the table to support a variety of games played as well as for training purposes. A host of applications on a billiard table would benefit by augmenting the table to support the attachment of precisely targeted overhead light sources. LED laser projectors (or 3D laser ray scan projection devices) can be used to project still or animated images of event logos, sponsors, gameplay indicators or scoring information, can also be projected onto the table surface and/or onto the floor area surrounding the table, pre or post-game, or presented during half-time or commercial break, for example - to be seen by fans and players.

For training purposes, carefully aligned projectors can be calibrated to focus light (images) directly on top of specific billiard table surfaces such as the rails, cushions to measure bank shots and kick shots for training and visualization purposes. Coupled with interactive software, extremely effective remote coaching can be facilitated. Projections can be static or dynamically generated and animated to support visualizations of ball positions and ball paths over time.

The projections help to make possible a number of interactive and digitally enhanced experiences on a billiard table. One application and implementation includes virtual gameplay with a remote player where the motions of the balls at one venue are recorded, forwarded, and projected remotely onto a table surface at their opponent's remote location - and visa versa - so that the two opponents can more directly visualize each other’s plays and responses and thus simulate the experience of actually playing them in person by watching their opponents remote actions unfold in front of them as projections atop their local equipment.

Another application includes remote (or local) instruction by a coaching where helpful and instructive lines are drawn onto a tablet device by a mentor, which is rendered directly onto a remote student’s table to convey the correct guidance to be studied. Such direct guides would drastically augment the real experience of playing billiards while facilitating accelerated learning.

When playing billiards, there are always a number of important markings permanently installed on the table (generally, either adhered with a pressure sensitive sticker, inked-in with a pen, or written-in, less permanently, using a fabric pencil, for example ) Table markings are customary and often specific to certain games commonly played on a billiards table. For example, for all games currently played, the “foot spot” is a point on the “foot” side (racking side) of the table to indicate where one should rack the balls. The “head string” is the horizontal line that spans the width of the table which usually designates where the player should break from (“behind the line”). In 14.1 straight pool, the outer boundary of the rack outline is etched onto the table so that players can plan ahead to prepare the positioning of their last ball and continue their continuous runs.

In carom billiards, certain games require specific “balk lines” to be present on the table in order to regulate legal zones during plays in the game. A set of 5 to 9 spot markings are commonly used to designate where to position balls at the start of the game or during certain moments when balls need to be re-spotted.

Temporarily drawn markings and lines can be extremely useful training and practice tools. Usually, such markings never get drawn permanently on publicly used tables and are only seen on home-tables or in training centers

The downside to physically drawing these markings are numerous: Once inked, they cannot be removed. Certain games require different markings and some markings are irrelevant or distracting when playing other games. - When obligated to place a ball directly onto a marking, one’s vision is naturally obstructed by the ball, so precise positioning is extremely challenging. - Cloth often stretches and shifts over time and cause the position of the markings to shift and/or fade away.

- Sticker markings often disrupt the path of the balls rolling over them. - It is not possible to easily configure. Lasers and projection patterns presented from directly above are useful to: - Precisely position a ball onto a designated spot. - Determine the winner of the lag. - Visualize lines and aiming points during practice - Organize training regimen and exercises - Can be reconfigured to adapt to whatever game or format is currently being played.

Players spend decades learning to understand exactly how to see and align themselves straight behind their shots before they can learn to shoot straight. It is a challenge and a struggle to understand the perspectives of each eye and position their bodies accordingly. Coupled together with the overhead mounted laser alignment line, a glass sphere, the size of a billiard ball, interacts with the laser beam overhead and provides an extremely clear and unique feedback to the player about precisely where their head is in relationship to the balls.

A glass (or acrylic) cue ball acts as a prism when interacting with the overhead light and refracts the light in a unique way to provide revealing alignment indications which are beneficial to help the practitioner understand the relationship of their head and eyes to the cue ball

DETAILED DESCRIPTION

Referring to the drawings, FIG. 1A is a plan view of the first embodiment which includes a light frame 10 which includes a center extending arm 19 having a coupling 19.1 which is axially slidable on rails of the frame 10. This arm 19 includes an extension section 19.2 which has inside a power and control feed 19.3. There is a first light 19.4 which is an optional light which extends up above towards the ceiling which indicates that the device is “on”. In addition, there is a light 19 5 which is a laser light which shines down on ball maker 17.2 and which is used to either allow the placement of a triangle rack 21 or the marking of the cue ball on that spot.

The billiard table 14 includes a plurality of pockets 9.1 , 9.2, 9.3, 9.4, 9.5, .and 9.6. This table also includes another ball marker 17.1. There are also a plurality of side ball placement markers on the rails of the table 15 including markers 15.1 , 15.2, 15.3, 15.4, 15.5, 15.6, 15.7, 15.8, 15.9.

FIG. 1 B shows a plan view of the frame 10 which includes the arm 19. In this case the pool table or billiard table 14 is shown in dashed dotted lines. The frame 10 includes sides 7, 11 , 12 and 13. The arm 19 obtains power from the power lines inside of the frame 10 such as shown in FIG. 1 C which shows the cross-sectional view of these sections. For example, power line 19.3 obtains power from power supply 36 housed in frame 10. It may be remotely switched via the power controller 36c housed within the frame.

FIG. 1 C shows a cross-sectional view of a frame which houses at least one LED light. The light frame 10 comprises a frame 20 which comprises a lid 26 with a groove for sliding clamps. There is a lip groove 22 for holding the lens 40 and filter which includes a corner connection to a lens 40. There is also a segmented lid 26 to allow for containing various power drivers wiring and power distribution, computer controllers, and an exit hole 33 for RF antenna 34 to extend control of lighting (power, lumens, or color temperature) wirelessly in the remote range. A spacer bracket 29 comprising an aluminum heat sink 28 formed integral therein is positioned inside of the frame 20. The heat sink can optionally have grooves or fins for adding surface area for aiding in cooling, wherein the spacer bracket is configured to support the LED circuit board 32 for housing the LED’s 30. The LEDs 30 are LED chips forming a light source. There is an AC/DC power supply driver 36 having an AC power cord 36a which is configured to be plugged into a power supply (AC power supply). At the opposite end of the driver are low voltage DC power cables 35 to feed into the circuit board 32.

One or more additional AC power cords 36b tap from the external power line to provide power to any of the mounted peripherals (e.g., lasers, projects, etc.). Each powered peripheral device can be remotely switched via a wireless control unit 36c. Full control of the LED lights as well as the laser and projectors onto the table surface can be coordinated and balanced wirelessly via remotely running control software.

The lens 40 is a downlight lens configured to focus the light provided by the LED’s so that a focused beam is presented or produced from the frame 20. In certain sections, there are light blocking filters 40b which are configured to regulate the concentration of light on regions of the table, potentially applied to balance or compensate for external lighting conditions. For example, in this design, light blocking filters 40b are positioned on the periphery of the lens.

FIG. 1 C also shows a transceiver 36c disposed along line 36b to control the output of line 36b. In addition there is also shown transceiver 36d disposed inside of power box 36 to control the power being fed to the LED’s to control the brightness of the LED’s. In addition, there is also a controller 136 such as a smartphone which is configured to send instructions to these transceivers 36c and 36d. These instructions can be in the form of wireless instructions such as via WIFI, cellular, Bluetooth or any other suitable form of communication.

FIG. 2 is a side view of the light positioned over a table. In this view there is shown a cross-sectional view of frames 11 and 12 which produce the light for a table such as a billiard table. These frames 11 and 12 are positioned above the nose/ bumpers of the table. The billiard table 14 comprises bumpers 16. These bumpers 16 are wooden rails with a rubber cushion facing the inside of the table. Because a focused light is produced on these bumpers it creates a shadow from these bumpers thereby showing the presence of these bumpers more prominently because of the hard shadows that are produced by the lens 40 In previous different designs, a frame would be coupled to a diffuser and not a lens. When a diffuser is used instead of a lens, the diffuser “diffuses” or softens and spreads the light rather than focusing the light thereby causing a softening of the contours of the bumpers which makes the bumpers less visible. Therefore, in order to accentuate the presence of the bumpers, a lens is used instead of a diffuser. This allows for the creation of shadow areas 16.1 and 16.2 underneath bumpers 16. In addition, blocking filters such as blocking filters 40a and 40b are also used.

FIG. 3 is a plan view of another embodiment of the light which includes a rectangular frame 50. The rectangular frame 50 is a light base platform having longitudinal extension 52 and latitudinal extension 51 for forming a substantially rectangular light. The frame has a lid 59 which is segmented for access to power distribution lines and RF antenna wires. There is a center beam 58 which is coupled at each end via clamps 53 and 63 to the latitudinal (shorter) extensions 51 . Coupled to this center beam 58 is a laser line projector 54 and a laser 60. Laser 60 is coupled to coupler 60.1 .

This laser line projector 54 housed in a coupling 54.1 and is adjustable fore/and aft can sway have a fan angle. In at least one embodiment this laser line 14b extends latitudinally. The laser line which is sent from the laser line projector 69 is for an extended line 14i extending across the length of the table and which is used for alignment of the light. The laser dot coupler 60.1 is for setting a laser light 60 for the rack point of the triangle. In essence these laser light sources are positioned over a center region of the table and are used for dispersing light to the table so that the outer frame 50 can be positioned above the table to create a substantially even distribution of light while still providing for substantial shadowing of the bumpers on the billiard or pool table. There are slidable mounts such as mount 65 or 63 which can be slidable along the latitudinal expanse 51 of the frame 50. There is also a rib 66 which is coupled to the outer frame 50 via sliding bracket or mount 57 as well. The frame 50 is formed from the individual frames 7, 11 , 12, and 13 shown in FIG. 1 B. with each of the latitudinal expanse 51 and the longitudinal expanse 52 formed from these frames 20 (See FIG. 1 C) to create a substantially rectangular light frame housing LED lights which are configured to shine down on a table.

This frame can be embedded into a ceiling such as a drop ceiling or hung from a ceiling as well. Rib 66 is coupled to center beam 58 via locking couplers 55 and 56, with rib also being slidable on the longitudinal expanse 52 via sliding mount 57. The locking couplers comprise a tubular spine coupling section (telescopic) with locking mechanism

56. The center beam forms 58 forms a spine section with power/control which has wire holes for wire management. All of these wires are hidden inside the tubular spine for a clean and neat look. There is also a tubular spine segment protrusion 63.1 for coupling/locking extension arms at foot of the table. In addition, there are tubular spine segment protrusion for coupling/locking extension arms at head of table 65 as well. Tubular rib segment 66 shows a protrusion for coupling/locking extension arms outside of table. In addition, there is a laser line projector 69 coupled to coupling 61 .1 and which is for projecting a laser line 14i.

FIG. 4A is a top view of a pocket billiards table showing the lighting effects that can be created on the table with the laser line projected by the laser line projector 54 (See FIG. 3) on the table. For example, line 14i is a laser projection line created by laser projector 69 positioned below laser 61 . This laser line 14i is projecting onto the floor and ending on the table from laser line creator 54. This line is used for footwork training. In addition, triangle 14a is used as a three-segment set of lines using three-line drawing lasers (See laser 61 which is three separate line lasers forming a triangle 14a) with cut off filters to control the length of the line laser. Line 14b can be created by laser 54 is a laser line projection to form the head-string which is the line where the player is required to place the cue ball behind. This line is produced by an overhead laser line producer 61 using beam limiters or filters to cut off the beam at the edge of the bumpers.

FIG. 4B is another top view of a pocket billiards table having extending arms 19 and 29 extending from frame 20 (See FIG. 1 B showing frame 20).. These arms 19 and 29 are coupled to the frame 20. Arm 29 is used to mount laser line producer 29.4 which is used to mark the head-string 14b, or zone from where the opening break shot is taken. Arm 19 is used to mount laser line producer 19.6 and project a useful line for aligning the racking device 14.1 on the opening shot as well as re-spot balls during play. A laser line producer 19 7 is also positioned on arm 19 to create laser line 14i. Essentially these line components are defined as follows:

14b: Head-string laser projection produced by a single laser line producer 29.4.

14h: Rack alignment laser projection produced by a single laser line producer 19.6 spanning from the center marker of the end-rail to the foot-spot. This line acts as a guide to coincide with the centered markings 149a and 149b of a specially marked ball racking device 149 (e.g., triangle frame or template) to ensure that the arrangement of the racked balls at the start of each game is symmetrical to the table.

14i: center line extending lengthwise along the center of the table created by the line laser 29.3

There is also a laser 19.8 coupled to arm 19, which creates a spot or marking

(temporary) 14k to mark the location of the placement of the cue ball on this end of the table. Each of these arms is fed with an electrical input from frame 20 and is configured to be controlled by the controller 136 communicating with transceivers 36d and 36c.

FIG. 40 is top view of a pocketless carom billiard table having a “spine” beam 58 extending arm 58 wherein the laser lines can show balk lines 14d for special games. In this view there are multiple extending arms 29.1 , 29.2, 29.6, 29.7. These arms each have laser line projectors 129.1 , 129.2, 129.6, and 129.7 respectively, for producing balk lines 14d to mark playing zones within each comer of the carom billiards table.

On extending arm 58 the laser dot producer 141.1 can be used to show one or more spots such as the head spot(s) 14e, (produced by a single laser dot) the center spot 14f, as well as the foot spot 14g. Other useful ball-marking spots 141 may be projected onto fixed positions on the table by mounting laser beam dot producers onto any number of tubular ribs 66 that are coupled to the spine and frame.

Essentially these components are defined as follows:

14d: Balkline line projection produced by laser line producer 129.1 , 129.2, 129.6, and 129.7 directly mounted overhead (on arms with beam limiters).

14e: Head spot laser projection produced by single laser beam dot 141.1 mounted onto the spine directly over the head-spot.

14f: Center spot laser projection produced by single laser beam dot 141.2 mounted onto the spine directly over the center-spot.

14g: Foot spot laser projection produced by single laser beam dot 141.3 mounted onto the spine directly over the foot-spot.
