Definitions

  • the present invention relates to the field of decorative light systems such as those utilized for holiday decorations and those used in year-round displays frequently seen at restaurants, shops, or hotels, and more particularly to programmable decorative light systems capable of displaying a vast selection of colors and flashing patterns.
  • large-bulb incandescent light sets generate appreciable amounts of heat which can lead to fire hazards. For this reason, large-bulb incandescent light sets are not properly usable indoors. Finally, large-bulb light sets are costly both to purchase and to maintain.
  • miniature incandescent light set Another option for outdoor lighting available in the current market is known as a miniature incandescent light set. While this type of light set can be used indoors and out-of-doors and is less expensive to purchase and maintain than the large-bulb incandescent light set, there are several drawbacks associated with miniature light sets.
  • Lamps on miniature light sets may be connected in series and can be extremely difficult to maintain. In some sets, a single burned-out lamp results in an open circuit that prevents operation of other lamps in the strand until the defective lamp is replaced. In newer sets, a shunt may be present to allow current to pass to the rest of the strand even when a bulb burns out, but the shunt does not prevent malfunction of the entire strand where a bulb becomes slightly dislodged from its socket. In that case, the user must locate the loose bulb and either secure or replace it. This may mean systematically checking each lamp on the strand, which can be both time-consuming and frustrating. Most users are likely to conduct such a search while the strand remains plugged into the power source, thereby risking electrical shock.
  • the lamps themselves are small, difficult to grasp, difficult to remove, and delicate to handle. Consequently, time spent searching for a defective lamp and the associated risk of injury from shock or from crushing the glass portion of the lamps while removing and replacing them is burdensome at best. Sometimes, entire light sets are often discarded even if only a single lamp is defective, making repeated purchases of conventional decorative light sets less cost effective than their price would indicate.
  • the lamps in miniature incandescent light sets are typically driven by low voltage alternating current (AC), which is usually achieved through a step-down transformer that converts standard 120 volt AC power to 12 volt AC power. While this reduces potential danger from voltage as compared to the large-bulb incandescent light systems, it also means that a user must have access to an AC outlet, necessarily limiting the use of conventional light sets to certain applications where AC power is convenient. Further, if multiple extension cords are necessary, a display can quickly become both unattractive and hazardous with respect to circuit overload and fire.
  • AC alternating current
  • miniature light sets allow a user to connect multiple strands of lamps to one another to create longer strands for more extensive applications or for the convenience of avoiding multiple extension cords in a single application, a user is still constrained by high current draws that could overload the circuit and permanently damage the light set.
  • Another practical problem with miniature light sets is the difficulty of creating dense or intricate light displays because the lamps on miniature light sets have a fixed space, usually 4 to 6 inches or more from one another.
  • a user In order to create clusters of lights or complex light displays, a user must re- wrap or double back on multiple times to achieve the desired results. This often leads to problems with tangling and breakage, especially if a bulb is loose or needs replacing or if the light strands must be taken down often, such as in a seasonal or temporary applications.
  • extending the string to extend the power to the next object removes the ability to eliminate the presence of lights between obj ects.
  • a further issue with miniature light sets is the limited range of available light colors. Even assuming that a user might be satisfied with the few lamp colors available on the market for miniature light sets, changing the color scheme on even a single strand of conventional lights is problematic, and more so for multiple strands of lights. Again, because the lights are small, delicate, and difficult to remove and replace, a user is likely to decide against changing color schemes to avoid the extra effort required to change colors. Further, a change in color scheme would require that a user separately purchase as many lamps as he desires to change, since most miniature light sets only come with 2 or 3 extra replacement bulbs. Although the cost of purchasing all-new replacement lamps is not necessarily prohibitive, the difficulty of finding enough replacement lamps in the desired replacement color is often difficult if not impossible. Practically, then, a user is more likely to purchase an entire new light set when new colors are desired, but even then, the selection of available colors remains small.
  • Flashing patterns in miniature light sets are generally pre-set and cannot be overridden or changed by the user. In fact, in many light sets, the user may have only two choices, either full-on or blinking. In the more basic miniature light sets, the blinking pattern is usually be achieved by replacing a regular lamp with a "flasher" lamp containing a bi-metallic strip. The strip responds to the heat of the bulb's filament and either closes or opens the circuit, turning on or off the bulbs, respectively. Unfortunately, the strand will not light at all when the blinker bulb burns out.
  • any defect or damage to the flasher bulb may further limit a user's options with respect to flashing patterns. Even in the more advanced miniature light sets run by a controller, available flashing patterns are usually preset and the selection is limited.
  • a sculptable, decorative light system includes a number of modules or capsules of differing lengths which can respond to commands either in parallel or time delay to create pre-selected light colors and sequences.
  • Three miniature connectors are used to create a direct current fed system which has the potential to even out a current demand.
  • Interconnectable light modules or capsules are provided in sets of 1, 2, 3, 4, and more lengths to create decorative light displays.
  • Each light module or string of modules or capsules may include a male/plug end and a female/receptacle end.
  • the complementary ends of adjacent connectors or strings of connectors may be joined to one another directly. Where it is desired for power to be extended to another structure without lights an extension connector can be used.
  • the interconnectable light modules or capsules can be manufactured to rely upon their interconnector conductors and insulation as a string support, or for interconnection using a series of short lengths of flexible tubing encasing the internal wiring and the light module.
  • the flexible tubing can help to ensure flexibility throughout the entire light system when the light modules or capsules are connected to one another, to thus avoiding breakage and allowing for a wider range of applications.
  • each light module facilitates a parallel connection of the light module with at least 2 other light modules or capsules.
  • junction connectors in the shape of either a "Y" or "T” can enable multiple light modules or capsules to be connected together to form unusual or complex shapes. Because all components of the present invention are standardized construction of the basic module is simple, and several embodiments will be demonstrated. Further, where a user is provided with different lengths having different numbers of modules or capsules, a user can easily expand a light system of any size or complexity at any time to any extent by simply purchasing additional module sets. Thus, the user can avoid the often protracted search for compatible components that is commonly associated with any attempt to expand or modify conventional light sets.
  • each light module may contain up to three incandescent light sources such as or light emitting diodes (LEDs), and a micro control unit (MCU). Either or both the MCU or LEDs can be mounted on a small printed circuit board (PCB) within the light module.
  • PCB printed circuit board
  • the light source for the light modules or capsules will herein be referred to simply as LEDs.
  • the MCU inside each light module may be as simple as a flip-flop or as complex as a microprocessor.
  • the resulting strand of light modules or capsules may be ultimately connectable to a master unit which houses both the power source for the light system and, in advanced embodiments, a controller.
  • the master unit is capable of simultaneously accommodating and powering numerous strands of interconnected light modules or capsules, the number and size of strands limited only by the capabilities of the power source.
  • each module having a microprocessor assumes a "default program" when it powers up and either fails to sense another source of control or fails to have its control ability overridden.
  • the present invention is direct current driven.
  • the lights may be controlled by the timing of a master unit with passive or natural reaction of the light modules or capsules.
  • module microprocessors may be able to receive instructions on timing, actuation, color, sequence, and the like.
  • the master controller may be enabled to automatically determine the number of modules or capsules connected to the master controller, as well as the lengths of the branching connections.
  • an extended control is facilitated by providing a sets of modules or capsules with an identifiable master module and a number of designated slave modules or capsules.
  • an identifiable master module By designating a small number of slave modules or capsules, a slightly lesser degree of independence can be exchanged for less computational capability and expense for the slave units.
  • the overall light system "sculptability" will not suffer as any string can be finished with independent units or groups of independent units. It may be preferable, for example to provide a home sculpting kit having a cluster one independent master module with three slave modules or capsules permanently wired to it, especially where the users will make more intricate patterns with more "Y" connectors and the like.
  • a sculpting kit having a cluster with one independent master module with nineteen or thirty nine slave modules or capsules permanently wired to it, to save workers the time necessary to make up extended strings, as well as to provide more connective integrity for commercial applications which are more likely to be subjected to wind, longer strings and more stress over a longer period of time.
